Introduction
Operating safety
Warning! G
Work improperly carried out on electronic components and associated software could cause them to cease functioning. Because the vehicle’s electronic components are interconnected, any modifications made may produce an undesired effect on other systems. Electronic malfunctions could seriously impair the operating safety of your vehicle.
See an authorized Mercedes-Benz Center for repairs or modifications to electronic components.
Other improper work or modifications on the vehicle could also have a negative impact on the operating safety of the vehicle.
Some safety systems only function while the engine is running. You should therefore never turn off the engine while driving.
Warning! G
Heavy blows against the vehicle underbody or tires / wheels, for example when running over an obstacle, road debris or a pothole, may cause serious damage to and impair the operating safety of your vehicle. If you feel a sudden significant vibration or ride distur­bance, or you suspect that damage to your vehicle has occurred, you should turn on your hazard warning flashers, carefully slow down, and drive with caution to an area which is a safe distance from the road.
Inspect the vehicle underbody and tires / wheels for possible damage. If the vehicle appears unsafe, have it towed to the nearest authorized Mercedes-Benz Center or other qualified maintenance or repair facility for further inspection or repairs.

Proper use of the vehicle

Proper use of the vehicle requires that you are familiar with the following information and rules:
the safety precautions in this manual
the “Technical data” section in this
manual
traffic rules and regulations
motor vehicle laws and safety
standards
Warning! G
Various warning labels are attached to your vehicle. These warning labels are intended to make you and others aware of various risks. You should not remove any of these warning labels unless explicitly instructed to do so by information on the label itself. Removal of any of these labels may cause you and others to be unaware of certain risks which may result in an accident and/or personal injury.

Adjusting
Getting started
Adjusting
Warning! G
All seat, head restraint, steering wheel, and rear view mirror adjustments, as well as fas­tening of seat belts, must be done before the vehicle is put into motion.
Seats
Warning! G
Do not adjust the driver’s seat while driving. Adjusting the seat while driving could cause the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat back in an excessively reclined position as this can be dangerous. You could slide un­der the seat belt in a collision. If you slide under it, the belt would apply force at the ab­domen or neck. That could cause serious or fatal injuries. The seat back and seat belts provide the best restraint when the wearer is in a nearly upright position and belts are properly positioned on the body.
Warning! G
Your seat must be adjusted so that you can correctly fasten your seat belt.
Observe the following points:
Adjust the backrest until your arms are
slightly angled when holding the steer­ing wheel.
Adjust the seat to a comfortable seating
position that still allows you to reach the accelerator/brake pedal safely. The po­sition should be as far back as possible with the driver still able to operate controls properly.
Adjust the head restraint so that it is as
close to the head as possible and the center of the head restraint supports the back of the head at eye level.
Never place hands under the seat or
near any moving parts while a seat is be­ing adjusted.
Failure to do so could result in an accident and/or serious personal injury.
Warning! G
When leaving the vehicle, always remove the SmartKey or SmartKey with KEYLESS-GO* from the starter switch, take it with you, and lock the vehicle.
Even with the SmartKey or SmartKey with KEYLESS-GO* removed from the starter switch, or the SmartKey with KEYLESS-GO* removed from the vehicle, the power seats can be operated when the respective door is open. Therefore, do not leave children unat­tended in the vehicle, or with access to an unlocked vehicle. Unsupervised use of vehi­cle equipment may cause an accident and/or serious personal injury.
41

Adjusting
Warning! G
According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seat­ing position. Thus, we strongly recommend that children be placed in the rear seats whenever possible. Regardless of seating position, children 12 years old and under must be seated and properly secured in an appropriate infant, or toddler restraint, or booster seat recommended for the size and weight of the child. For additional information, see “Children in the vehicle” (
page 83).
A child’s risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and/or the child is not properly secured in the child restraint.

Warning! G
For your protection, drive only with properly positioned head restraints.
Adjust the head restraint so that it is as close to the head as possible and the center of the head restraint supports the back of the head at eye level. This will reduce the po­tential for injury to the head and neck in the event of an accident or similar situation.

The head restraint returns to its previ­ous position.
In addition to the front seat backrests, the
i
front seat cushions can also be shifted forward to permit easy access to the rear whenever the seat is located in the rear half of its adjustment range. Pivot backrest forward by pulling the re­lease lever until the seat moves in a combined forward and upward movement.
When moving the seat, make sure there are
!
no items in the footwell or behind the seats. Oth­erwise you could damage the seats.
Warning! G
The seat belts provide protection only with the backrest locked in place. Therefore, the backrest must be locked in place with the vehicle in motion. Do not drive the vehicle when the backrest is not locked in place.
When leaving the vehicle, always remove the SmartKey or SmartKey with KEYLESS-GO* from the starter switch, take it with you, and lock the vehicle.
The power seats can also be operated with the driver’s or passenger door open. Do not leave children unattended in the vehicle or with access to an unlocked vehicle. Unsu­pervised use of vehicle equipment may cause an accident and/or serious personal injury.
Never place hands under seat or near any moving parts during a seat adjustment procedure.
For information on additional convenience features permitting easy entry and exit, see “Easy-entry/exit feature” (
page 45).

Steering wheel

Warning! G
Do not adjust the steering wheel while driv­ing. Adjusting the steering wheel while driv­ing could cause the driver to lose control of the vehicle.
When leaving the vehicle, always remove the SmartKey or SmartKey with KEYLESS-GO* from the starter switch, take it with you, and lock the vehicle.
Even with the SmartKey or SmartKey with KEYLESS-GO* removed from the starter switch, or the SmartKey with KEYLESS-GO* removed from the vehicle, the steering wheel adjustment feature can be operated when the driver’s door is open. Therefore, do not leave children unattended in the ve­hicle, or with access to an unlocked vehicle. Unsupervised use of vehicle equipment may cause an accident and/or serious personal injury.

Driving
Warning! G
Make sure absolutely no objects are ob­structing the pedals’ range of movement. Keep the driver’s footwell clear of all obsta­cles. If there are any floormats or carpets in the footwell, make sure the pedals still have sufficient clearance.
During sudden driving or braking maneu­vers, the objects could get caught between or beneath the pedals. You could then no longer brake or accelerate. This could lead to accidents and injury.
Fastening the seat belts
Warning! G
Always fasten your seat belt before driving off. Always make sure your passengers are properly restrained, even those sitting in the rear.
Failure to wear and properly fasten and po­sition your seat belt greatly increases your risk of injuries and their likely severity in an accident. You and your passengers should always wear seat belts.
If you are ever in an accident, your injuries can be considerably more severe without your seat belt properly buckled. Without your seat belt buckled, you are much more likely to hit the interior of the vehicle or be ejected from it. You can be seriously injured or killed.
In the same crash, the possibility of injury or death is lessened if you are wearing your seat belt. The air bags can only provide the protection they where designed to afford if the occupants are using their seat belts (
page 64).
Warning! G
According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seat­ing position. Thus, we strongly recommend that children be placed in the rear seats. Regardless of seating position, children 12 years old and under must be seated and properly secured in an appropriate infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. For additional information, see “Chil­dren in the vehicle” (
A child’s risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and/or the child is not properly secured in the child restraint.
page 83).
48
Page 50
Warning! G
Never let more people ride in the vehicle than there are seat belts available. Be sure everyone riding in the vehicle is correctly restrained with a separate seat belt. Never use a seat belt for more than one person at a time.
Warning! G
Never ride in a moving vehicle with the seat backrest in an excessively reclined position as this can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the belt would apply force at the ab­domen or neck. This could cause serious or even fatal injuries. The seat backrest and seat belt provide the best restraint when the wearer is in a nearly upright position and the belt is properly positioned on the body.
Warning! G
Read and observe the additional warning no­tices printed in the “Safety and Security” section (
page 68).
The seat belt presenter for driver and pas­senger makes it easier to put on the seat belt.

Place the shoulder portion of the belt
across the top of your shoulder and the lap portion across your hips.
Push latch plate 1 into buckle 3 until
it clicks.
If necessary, tighten the lap portion to
a snug fit by pulling shoulder portion up.
Proper use of seat belts
Do not twist the belt when fastening.
Adjust seat belt so that the shoulder
portion is located as close as possible to the middle of the shoulder (it should not touch the neck). Never pass the shoulder portion of the belt under your arm.
Position the lap belt as low as possible
on your hips (over hip joint) and not across the abdomen.
Place the seat backrest in a position
that is as upright as possible.
Never use a seat belt for more than one
person at a time.
Do not fasten a seat belt around a
person and another object at the same time.
When using a seat belt to secure i nfant
restraints, toddler restraints or chil­dren in booster seats, always follow the child seat manufacturer’s instructions.
Check your seat belt periodically
during travel to make sure it is properly positioned.
Make sure the seat belt is always fitted
snugly. Take special care of this when wearing loose clothing.
Warning! G
Do not pass belts over sharp edges. They could tear.
Do not allow the belt to get caught in the door or in the seat adjustment mechanism. This could damage the belt.
Never attempt to make modifications to seat belts. This could impair the effective­ness of the belts.
Do not bleach or dye seat belts as this may severely weaken them. In a crash they may not be able to provide adequate protection.
Damaged seat belts or belts that were highly stressed in an accident must be replaced. Contact an authorized Mercedes-Benz Center.

The SRS system conducts a self-test when the ignition is switched on and in regular intervals while the engine is running. This facilitates detection of system malfunc­tions. The 1 indicator lamp in the in­strument cluster comes on when the ignition is switched on and goes out no lat­er than a few seconds after the engine has been started.
The SRS components are in operational readiness if the 1 indicator lamp is not lit when the engine is running.

Occupant safety
Warning! G
Modifications to or work improperly con­ducted on restraint systems (such as seat belts and anchors, emergency tensioning devices, seat belt force limiters or air bags) or their wiring, as well as tampering with in­terconnected electronic systems, can lead to the restraint systems no longer function­ing as intended.
Air bags or emergency tensioning devices, for example, could deploy inadvertently or fail to deploy in accidents although the de­celeration threshold for air bag deployment is exceeded. Therefore, never modify the re­straint systems. Do not tamper with elec­tronic components or their software.
Warning! G
In the event that the 1 indicator lamp comes on during driving or does not come on at all, the SRS self-check has detected a malfunction. For your safety, we strongly
recommend that you visit an authorized Mercedes-Benz Center immediately to have the system checked; otherwise the SRS may not deploy when needed in an accident, which could result in serious or fatal injury, or it might deploy unexpectedly and unnec­essarily which could also result in injury.
In addition, improper repair work on the SRS creates a risk of rendering the SRS inopera­tive or causing unintended air bag deploy­ment. Work on the SRS must therefore only be performed by qualified technicians. Con­tact an authorized Mercedes-Benz Center.
If it is necessary to modify an air bag system to accommodate a person with disabilities, contact your local authorized Mercedes-Benz Center or call our Customer Assistance Center at 1-800-FOR-MERCedes (1-800-367-6372) for details.

Air bags

Warning! G
Air bags are designed to reduce the poten-
tial of injury and fatality in certain frontal im-
pacts (front air bags) or side impacts (CLK
coupe: front side impact air bags, rear side
impact air bags*, and window curtain air
bags. CLK cabriolet: head-thorax air bags
and rear side impact air bags*). However, no
system available today can completely elim-
inate injuries and fatalities.
The deployment of the air bags temporarily
releases a small amount of dust from the air
bags. This dust, however, is neither injurious
to your health, nor does it indicate a fire in
the vehicle. The dust might cause some tem-
porary breathing difficulty for people with
asthma or other breathing trouble. To avoid
this, you may wish to get out of the vehicle
as soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle after the air bag inflates, then get
fresh air by opening a window or door.
65
Page 67
Safety and Security
Occupant safety
Warning! G
To reduce the risk of injury when the front air bags inflate, it is very important for the driver and front passenger to always be in a properly seated position and to wear their respective seat belts.
For maximum protection in the event of a collision always be in normal seated position with your back against the backrest. Fasten your seat belt and make sure it is properly positioned on your body.
Since the air bag inflates with considerable speed and force, a proper seating and hands on steering wheel position will help to keep you at a safe distance from the air bag. Occupants who are unbelted, out of position or too close to the air bag can be seriously injured or killed by an air bag as it inflates with great force in the blink of an eye:
Sit properly belted in a position that is
as upright as possible with your back against the seat backrest.
Adjust the driver’s seat as far as possi-
ble rearward, still permitting proper op­eration of vehicle controls. The distance from the center of the driver’s breast­bone to the center of the air bag cover on the steering wheel must be at least 10 in (25 cm) or more. You should be able to accomplish this by a combina­tion of adjustments to the seat and steering wheel. If you have any prob­lems, please see an authorized Mercedes-Benz Center.
Do not lean your head or chest close to
the steering wheel or dashboard.
Keep hands on the outside of steering
wheel rim. Placing hands and arms in­side the rim can increase the risk and potential severity of hand/arm injury when driver’s front air bag inflates.
Adjust the front passenger seat as far as
possible rearward from the dashboard when the seat is occupied.
Occupants, especially children, should
always sit as upright as possible, properly use the seat belts and use an appropriately sized infant restraint, toddler restraint, or booster seat recom­mended for the size and weight of the child.
Failure to follow these instructions can re­sult in severe injuries to you or other occupants.
If you sell your vehicle, it is important that you make the buyer aware of this safety information. Be sure to give the buyer this Operator’s Manual.

Occupant safety
Warning! G
CLK coupe:
Accident research shows that the safest place for children in an automobile is in the rear seat.
There is a possibility for a side impact air bag related injury if occupants, especially children, are not properly seated or re­strained when next to a front side impact air bag and/or rear side impact air bag* which needs to deploy rapidly in a side impact in order to do its job.
To help avoid the possibility of injury, please follow these guidelines:
(1) Occupants, especially children, should
never place their bodies or lean their heads in the area of the door or the rear side trim panel where the front side im­pact air bag and/or the rear side impact air bag* inflates.
This could result in serious injuries or death should the front side impact air bag and/or the rear side impact air bag* be deployed.
(2) Always sit as upright as possible,

(3) Always wear seat belts properly.
If you believe that, even with the use of these guidelines, it would be safer for your rear seat occupants to have the rear mount­ed side impact air bags* deactivated, then deactivation can be accomplished upon your written request to do so at an autho­rized Mercedes-Benz Center at an additional cost.
Please contact your local authorized Mercedes-Benz Center or call our Customer Assistance Center at 1-800-FOR-MERCedes (1-800-367-6372) for details.
Warning! G
CLK cabriolet:
Accident research shows that the safest
place for children in an automobile is in the
rear seat.
There is a possibility for a head-thorax air
bag or rear side impact air bag* related inju-
ry if occupants, especially children, are not
prop er ly seat ed or rest rain ed wh en n ext to a
head-thorax air bag and/or rear side impact
air bag* which needs to deploy rapidly in a
side impact in order to do its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Always sit as upright as possible,
properly use the seat belts and for children 12 years old and under, use an appropriately sized infant restraint, toddler restraint or booster seat recom­mended for the size and weight of the child.
(2) Always wear seat belts properly.

Air bags are designed to deploy only in cer-
i
tain frontal impacts (front air bags) and in side impacts (CLK coupe: front side impact air bags, rear side impact air bags*, and window curtain air bags. CLK cabriolet: head-thorax air bags and rear side impact air bags*) which exceed preset thresholds. Only during these events will they provide their supplemental protection.
The driver and passenger should always wear their seat belts. Otherwise it is not possible for the air bags to provide their supplemental protection.
In case of other types of impacts and impacts be­low air bag deployment thresholds, air bags will not deploy. The driver and passenger will then be protected to the extent possible by a properly fastened seat belt. A properly fastened seat belt is also needed to provide the best possible protection in a rollover.
We caution you not to rely on the presence of the air bags in order to avoid wearing your seat belt.
It is important to your safety and that of your pas­sengers that you replace deployed air bags and repair any malfunctioning air bags to make sure the vehicle will continue to provide supplemental crash protection for occupants.
Safety guidelines for the seat belt, emergency tensioning device and air bag
Warning! G
Damaged seat belts or belts that were
highly stressed in an accident must be replaced and their anchoring points must also be checked. Only use belts in­stalled or supplied at an authorized Mercedes-Benz Center.
Air bags and Emergency Tensioning
Devices (ETDs) contain Perchlorate material, which may require special han­dling and regard for the environment. Check with your local government’s dis­posal guidelines. California residents, see http://www.dtsc.ca.gov/Hazard­ousWaste/Perchlorate/index.cfm.
Air bags and emergency tensioning de-
vices (ETDs) are designed to function on a one-time-only basis. An air bag or ETD that is deployed must be replaced.
Do not pass belts over sharp edges.
They could tear.
Do not make any modification that could
change the effectiveness of the belts.
Do not bleach or dye seat belts as this
may severely weaken them. In a crash they may not be able to provide ade­quate protection.
No modifications of any kind may be
made to any components or wiring of the SRS. This includes changing or removing any component or part of the SRS, the installation of additional trim material, badges, seat covers (CLK cabriolet) etc. over the steering wheel hub, front passenger front air bag cover, outboard sides of the front seat backrest (CLK cabriolet), door trim pan­els (CLK coupe), door frame trims (CLK coupe), or rear side trim panels, and in­stallation of additional electrical/elec­tronic equipment on or near SRS components and wiring. Keep area be­tween air bags and occupants free from objects (e.g. packages, purses, umbrel­las, etc.).

Occupant safety
CLK coupe: Do not hang items such as
coat hangers from the coat hooks or handles over the door. These items may turn into projectiles and cause head and other injuries when the window curtain air bag is deployed.
Air bag system components will be hot
after an air bag has inflated. Do not touch.
Never place your feet on the instrument
panel, dashboard, or on the seat. Always keep both feet on the floor in front of the seat.
In addition, improper repair work on the
SRS creates a risk of rendering the SRS inoperative or causing unintended air bag deployment. Work on the SRS must therefore only be performed by qualified technicians. Contact an authorized Mercedes-Benz Center.
For your protection and the protection
of others, when scrapping the air bag unit or emergency tensioning device, our safety instructions must be fol­lowed. These instructions are available from any authorized Mercedes-Benz Center.
Given the considerable deployment
speed, required inflation volume, and the textile structure of the air bags, there is the possibility of abrasions or other, potentially more serious injuries resulting from air bag deployment.
Warning! G
CLK cabriolet: Only use seat covers which
have been tested and approved by
Mercedes-Benz for your vehicle model. Us-
ing other seat covers may interfere with or
prevent the deployment of the head-thorax
air bags. Contact your authorized
Mercedes-Benz Center for availability.
When you sell your vehicle, we strongly urge you to give notice to the subsequent owner that it is equipped with an SRS by alerting them to the applicable section in the Operator’s Manual.

Front air bags
1 Driver air bag 2 Passenger air bag
Driver and front passenger front air bags are deployed:
in the event of certain frontal impacts
if impact exceeds a preset deployment
threshold
independently of the front side impact
air bag (CLK coupe), head-thorax air bag (CLK cabriolet) and/or the rear side impact air bag*
The front air bags in this vehicle have been
i
designed to inflate in two stages. This allows the air bag to have different rates of inflation that are based on the rate of relevant vehicle decelera­tion as assessed by the air bag control unit.
On the front passenger side, the front air bag de­ployment is additionally influenced by the pas­senger’s weight category as identified by the Occupant Classification System (OCS) (
page 72).
The lighter the front passenger side occupant, the higher the vehicle deceleration rate required for the second stage inflation of the air bag.
The air bags will not deploy in impacts which do not exceed the system’s deploy­ment thresholds. You will then be protect­ed by the fastened seat belts.
The front passenger front air bag will only be deployed if:
the system, based on OCS weight sen-
sor readings, senses that the front pas­senger seat is occupied
the 56 indicator lamp in the
center console is not lit (

Occupant Classification System
The O
ccupant Classification System (OCS) automatically turns the front passenger front air bag on or off based on the classi­fied occupant weight category determined by weight sensor readings from the front passenger seat.
CLK coupe: The system does not deactivate
i
the front passenger side impact air bag, the win­dow curtain air bag and the emergency tension­ing device.
CLK cabriolet: The system does not deactivate the head-thorax air bag and the emergency ten­sioning device.
Occupants must sit properly belted in a position that is as upright as possible with their back against the seat backrest and feet on the floor to be correctly classified. If the occupant's weight is transferred to another object in the vehicle (e.g. by leaning on armrests), the OCS may not be able to properly approximate the occupant’s weight category.
If your seat, including your trim cover and
i
cushion needs to be serviced in any way, take the vehicle to an authorized Mercedes-Benz Center.
Only seat accessories approved by Mercedes-Benz may be used.
Both driver and the front passenger should always use the 56 indicator lamp as an indication of whether or not the front passenger is properly positioned.

Warning! G
According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seat­ing position. Thus, we strongly recommend that children be placed in the rear seats whenever possible. Regardless of seating position, children 12 years old and under must be seated and properly secured in an appropriate infant or child restraint recom­mended for the size and weight of the child.
The infant or child restraint must be properly secured with the vehicle’s seat belt, the seat belt and top tether strap (CLK coupe), or lower anchors and top tether strap (CLK coupe), or seat belt and lower anchors (CLK cabriolet), fully in accordance with the child seat manufacturer’s instructions.
Children can be killed or seriously injured by an inflating air bag. Note the following important information when circumstances require you to place a child in the front passenger seat:
Your vehicle is equipped with air bag
technology designed to turn off the front passenger front air bag in your vehicle when the system senses the weight of a typical 12-month-old child or less along with the weight of a standard appropri­ate child restraint on the front passen­ger seat.
A child in a rear-facing child restraint on
the front passenger seat will be seriously injured or even killed if the front passenger front air bag inflates in a collision which could occur under some circumstances, even with the air bag technology installed in your vehicle. The only means to completely eliminate this risk is to never place a child in a rear-facing child restraint in the front seat. We therefore strongly recommend that you always place a child in a rear-facing child restraint in the back seat.
74
Page 76
If you must install a rear-facing child
restraint on the front passenger seat because circumstances require you to do so, make sure the 56 indica­tor lamp is illuminated, indicating that the front passenger front air bag is deac­tivated. Should the 56 indicator lamp not illuminate or go out while the restraint is installed, please check in­stallation. Periodically check the 56 indicator lamp while driving to make sure the 56 indicator lamp is illuminated.
If the 56 indicator lamp goes out or remains out, do not transport a child on the front passenger seat until the system has been repaired. A child in a rear-facing child restraint on the front passenger seat will be seriously injured or even killed if the front passenger front air bag inflates.
If you have to place a child in a
forward-facing child restraint on the front passenger seat, move the seat as far back as possible, use the proper child restraint recommended for the age, size and weight of the child, and secure child restraint with the vehicle’s seat belt according to the child seat manufacturer’s instructions. For children larger than the typical 12-month-old child, the front passenger front air bag may or may not be activated (
page 73).
Safety and Security
Occupant safety
Deployment of the driver front air bag does
i
not mean that the front passenger front air bag also should have deployed.
The Occupant Classification System ( may have determined:
that the seat was empty or occupied by the
weight up to or less than that of a typical 12-month-old child seated in a standard child restraint – both instances where the system suppresses deployment of the front passenger front air bag even though the im­pact met the criteria and was of sufficient severity to deploy the driver front air bag.
that the seat was occupied by a small individ-
ual (such as a young teenager or a small adult) or a child weighing more than the weight of a typical 12-month-old child in a standard child restraint – instances where the system may suppress deployment of the front passenger front air bag even though the impact met the criteria and was of suffi­cient severity to deploy the driver front air bag.

The 56 indicator lamp 1 will be illuminated, except with the SmartKey removed from the starter switch or with the starter switch in position 0.
Warning! G
If the 1 indicator lamp and the 56 indicator lamp are lit at the same time, there is a malfunction in the Occupant Classification System. The front passenger front air bag will be deactivated in this case.
Have the system checked as soon as possi­ble by qualified technicians. Contact an au­thorized Mercedes-Benz Center.
Only have the seat repaired or replaced at an authorized Mercedes-Benz Center.
In order to ensure proper operation of the air bag system and OCS:
Sit properly belted in a position that is
as upright as possible with your back against the seat backrest.
While seated, an occupant should not
position him/herself in such a way as to cause the occupant’s weight to be lifted from the seat bottom as this may result in the OCS being unable to correctly ap­proximate the occupant’s weight category.
Read and observe all warnings in this
chapter.
Self-test Occupant Classification System
After turning the SmartKey in the starter switch to position 1 or 2 or pressing the KEYLESS-GO* start/stop button once or twice, the 56 indicator lamp located in the center console illuminates. If an adult occupant is properly sitting on the front passenger seat and the system senses the occupant as being an adult, the 56 indicator lamp will illuminate and go out after approximately 6 seconds.
If the seat is not occupied and the system senses the front passenger seat as being empty, the 56 indicator lamp will illuminate and not go out.
76
Page 78
Warning! G
If the 56 indicator lamp should not illuminate, the system is not functioning. You must see an authorized Mercedes-Benz Center before seating any child on the front passenger seat.
More information can be found in the “Practical hints” section (
page 390).
Warning! G
Never place anything between seat cushion and child seat (e.g. pillow), since it reduces the effectiveness of the Occupant Classifi­cation System. The bottom of the child seat must make full contact with the passenger seat cushion. An incorrectly mounted child seat could cause injuries to the child in case of an accident, instead of increasing protec­tion for the child.
Follow the manufacturer’s instructions for installation of child seats.

Seat belts

The use of seat belts and infant and child restraint systems is required by law in all 50 states, the District of Columbia, the U.S. territories and all Canadian provinces.
Even where this is not the case, all vehicle occupants should have their seat belts fastened whenever the vehicle is in motion.
For more information, see “Fastening the seat belts” (
For information on infants and children trav-
i
eling with you in the vehicle and restraint sys­tems for infants and children, see “Children in the vehicle” (

Safety and Security
Occupant safety
Warning! G
Always fasten your seat belt before driving off. Always make sure all of your passengers are properly restrained, including those sit­ting in the rear.
Failure to wear and properly fasten and position your seat belt greatly increases your risk of injuries and their likely severity in an accident. You and your passengers should always wear seat belts.
If you are ever in an accident, your injuries can be considerably more severe without your seat belt properly buckled. Without your seat belt buckled, you are much more likely to hit the interior of the vehicle or be ejected from it. You can be seriously injured or killed.
In the same crash, the possibility of injury or death is lessened if you are properly wearing your seat belt. Air bags can only protect as they are designed if the occupants are properly wearing their seat belts.
77
Page 79
Safety and Security
Occupant safety
Warning! G
Never ride in a moving vehicle with the seat backrest in an excessively reclined position as this can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the belt would apply force at the abdomen or neck. That could cause serious or even fatal injuries. The seat backrest and seat belt provide the best restraint when the wearer is in a position that is as upright as possible and the belt is properly positioned on the body.
Warning! G
Never let more people ride in the vehicle than there are seat belts available. Make sure everyone riding in the vehicle is correctly restrained with a separate seat belt. Never use a seat belt for more than one person at a time.
Warning! G
Damaged seat belts or seat belts that were highly stressed in an accident must be re­placed and their anchoring points must also be checked.
Only use seat belts which have been approved by Mercedes-Benz.
Do not make any modifications to the seat belts. This can lead to unintended activation of the ETDs or to their failure to activate when necessary.
Do not bleach or dye seat belts as this may severely weaken them. In a crash they may not be able to provide adequate protection.
Have all work carried out only by qualified technicians. Contact an authorized Mercedes-Benz Center.
Warning! G
USE SEAT BELTS PROPERLY
Seat belts can only work when used
properly. Never wear seat belts in any other way than as described in this section, as that could result in serious injuries in case of an accident.
Each occupant should wear their seat
belt at all times, because seat belts help reduce the likelihood of and potential severity of injuries in accidents, includ­ing rollovers. The integrated restraint system includes SRS (driver air bag, passenger front air bag, CLK coupe: front side impact air bags, rear side im­pact air bags*, and window curtain air bags, CLK cabriolet: head-thorax air bags and rear side impact air bags*), ETD (seat belt emergency tensioning de­vice), and front seat knee bolsters. The system is designed to enhance the pro­tection offered to properly belted occu­pants in certain frontal (front air bags and ETD)

and side (CLK coupe: front side impact air bags, rear side impact air bags*, and window curtain air bags. CLK cabriolet: head-thorax air bags and rear side im­pact air bags* and ETD) impacts which exceed preset deployment thresholds.
Never wear the shoulder belt under your
arm, against your neck or off your shoul­der. In a frontal crash, your body would move too far forward. That would increase the chance of head and neck injuries. The belt would also apply too much force to the ribs or abdomen, which could severely injure internal or­gans such as your liver or spleen.
Never wear belts over rigid or breakable
objects in or on your clothing, such as eyeglasses, pens, keys, etc., as these might cause injuries.
Position the lap belt as low as possible
on your hips and not across the abdo­men. If the be lt is positioned across your abdomen, it could cause serious injuries in a crash.
Never use a seat belt for more than one
person at a time. Do not fasten a seat belt around a person and another person or other objects.
Belts should not be worn twisted. In a
crash, you wouldn’t have the full width of the belt to distribute impact forces. The twisted belt against your body could cause injuries.
Pregnant women should also always use
a lap-shoulder belt. The lap belt portion should be positioned as low as possible on the hips to avoid any possible pressure on the abdomen.
Never place your feet on the instrument
panel, dashboard, or on the seat. Always keep both feet on the floor in front of the seat.
When using a seat belt to secure infant
restraints, toddler restraints or children in booster seats, always follow the child seat manufacturer’s instructions.
Enhanced seat belt reminder system
When the engine is started, the seat belt telltale < will always illuminate for 6 seconds to remind you and your pas­sengers to fasten your seat belts.
If the driver’s seat belt is not fastened when the engine is started, an additional warning chime will also sound for a maxi­mum of 6 seconds or until the driver’ s seat belt is fastened.
If after these 6 seconds the driver’s or the front passenger’s seat belt (with the front passenger seat occupied) is not fastened with both doors closed,
the seat belt telltale < remains illu-
minated for as long as either the driv­er’s or front passenger’s seat belt is not fastened.

intensity for a maximum of 60 seconds or until the driver’s and the front pas­senger’s seat belt are fastened. If you and/or your passenger release the seat belt during driving, the seat belt telltale < starts flashing and a warning chime sounds as described be­fore.
If the driver’s or the front passenger’s seat belt remains unfastened after 60 seconds, the warning chime stops sounding, the seat belt telltale < stops flashing but continues to be illu­minated. After a vehicle standstill, the warning chime is reactivated and the seat belt telltale < is flashing again if the ve­hicle speed once exceeds 15 mph (25 km/h).
The seat belt telltale < will only go out if both the driver’s and the front passen­ger’s seat belt (with the front passenger seat occupied) are fastened, or the vehicle is standing still and a door is opened.
For more information, see “Practical hints” (
page 385).
Emergency tensioning device (ETD), seat belt force limiter
The seat belts are equipped with emergen­cy tensioning devices and belt force limiters.
The ETD is designed to activate in the following cases:
in frontal or rear-end impacts
exceeding the system deployment threshold
if the restraint systems are operational
and functioning correctly, see 1 indicator lamp (
The ETDs for the front seats will only acti-
i
vate if the front seat belts are fastened (latch plate properly inserted into buckle).
The ETDs for the rear seats will activate with or without the respective seat belts fastened.
page 64)
When activated, emergency tensioning devices remove slack from the belts. Belt force limiters reduce the force exerted by the seat belts on occupants during a crash.
Warning! G
An emergency tensioning device (ETD) that was activated must be replaced.
When disposing of the emergency tension­ing device, our safety instructions must be followed. These are available at any authorized Mercedes-Benz Center.

Active head restraints

The active front seat head restraints are in­tended to offer the driver and front passen­ger increased protection from whiplash type injuries in rear-end collisions. In the event of a rear-end collision exceeding the systems’ deployment threshold, the active head restraints on the driver’s and front passenger’s seats are designed to move forward in the direction of travel, providing the head with increased support earlier on in the collision sequence. The active head restraints activate whether the seat is oc­cupied or not.
Warning! G
For your protection, drive only with properly positioned head restraints.
Adjust the head restraint so that it is as close to the head as possible and the center of the head restraint supports the back of the head at eye level. This will reduce the
potential for injury to the head and neck in the event of an accident or similar situation.
Do not drive the vehicle without the seat head restraints. Head restraints are intend­ed to help reduce injuries during an accident.
Warning! G
Only use seat or head restraint covers which have been tested and approved by Mercedes-Benz for your vehicle model. Using other seat or head restraint covers may interfere with or prevent the activation of the active head restraints. Contact an authorized Mercedes-Benz Center for availability.
Do not attach any objects (e.g. hangers) to the head restraint posts. Otherwise, the ac­tive head restraints may not be able to func­tion properly or offer the intended degree of protection in the event of an accident.
You cannot remove the active head re­straint on the driver’s and front passen­ger’s seat. For removal of the active head restraints we recommend that you contact an authorized Mercedes-Benz Center.

The roll bars are integrated into the rear head restraints.
The roll bars raise automatically in an acci­dent or in a critical driving situation.
When the roll bars are raised automatically,
i
you will hear a ratcheting sound and the rear head restraints will also rise.
You can manually lower the roll bars again when the soft top is open (

Children in the vehicle

If an infant or child is traveling with you in the vehicle:
Secure the child using an infant or child
restraint appropriate to the age and size of the child.
Make sure the infant or child is proper-
ly secured at all times while the vehicle is in motion.
Warning! G
Do not leave children unattended in the vehicle, even if they are secured in a child restraint system. The children could
injure themselves on parts of the vehicle
be seriously or fatally injured through
excessive exposure to extreme heat or cold
If children open a door, they could
injure other persons
get out of the car and injure themselves
or be injured by oncoming traffic
Do not expose the child restraint system to direct sunlight. The child restraint system’s metal parts, for example, could become very hot, and the child could be burned on these parts.
Do not carry heavy or hard objects in the passenger compartment or trunk unless they are firmly secured in place. For more in­formation, see “Loading” ( see “Useful features” ( “Controls in detail” chapter.

Infant and child restraint systems
We recommend all infants and children be properly restrained at all times while the vehicle is in motion.
All lap-shoulder belts except the driver’s seat belt have special seat belt retractors for secure fastening of child restraints.
To fasten a child restraint, follow child restraint instructions for mounting. Then pull the shoulder belt out completely and let it retract. During seat belt retraction, a ratcheting sound can be heard to indicate that the special seat belt retractor is acti­vated. The belt is now locked. Push down on child restraint to take up any slack.
To deactivate, release seat belt buckle and let seat belt retract completely. The seat belt can again be used in the usual manner.
Warning! G
Never release the seat belt buckle while the vehicle is in motion, since the special seat belt retractor will be deactivated.

Infants and small children should be seat­ed in an appropriate infant or child restraint system properly secured in accor­dance with the manufacturer's instruc­tions for the child restraint, that complies with U.S. Federal Motor Vehicle Safety Standards 213 and 225 and Canadian Mo­tor Vehicle Safety Standards 213 and
210.2.
A statement by the child restraint manu­facturer of compliance with these stan­dards can be found on the instruction label on the restraint and in the instruction manual provided with the restraint.
When using any infant, or toddler restraint, or booster seat, be sure to carefully read and follow all manufacturer’s instructions for installation and use.
Please read and observe warning labels affixed to the inside of the vehicle and to infant or child restraints.
Warning! G
According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seat­ing position. Thus, we strongly recommend that children be placed in the rear seats whenever possible. Regardless of seating position, children 12 years old and under must be seated and properly secured in an appropriate infant or child restraint recom­mended for the size and weight of the child.
The infant or child restraint must be properly secured with the vehicle’s seat belt, or:
CLK coupe: the seat belt and top tether
strap, or lower anchors and top tether strap,
CLK cabriolet: the seat belt and lower
anchors,
fully in accordance with the child seat manufacturer’s instructions. Occupants, especially children, should nev­er place their bodies or lean their heads in the area of the door or the rear side trim panel where the front side impact air bag (CLK cabriolet: head-thorax air bag) and/or the rear side impact air bag* inflates. This could result in serious injuries or death should the air bag be triggered. Always sit as upright as possible, properly use the seat belts and use an appropriately sized infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. Children can be killed or seriously injured by an inflating air bag. Note the following important information when circumstances require you to place a child in the front passenger seat:

Safety and Security
Occupant safety
Your vehicle is equipped with air bag
technology designed to turn off the front passenger front air bag in your vehicle when the OCS senses the weight of a typical 12-month-old child or less along with the weight of a standard appropriate child restraint on the front passenger seat.
A child in a rear-facing child restraint on
the front passenger seat will be seriously injured or even killed if the front passenger front air bag inflates in a collision which could occur under some circumstances, even with the air bag technology installed in your vehicle. The only means to completely eliminate this risk is to never place a child in a rear-facing child restraint in the front seat. We therefore strongly recommend that you always place a child in a rear-facing child restraint in the back seat.
If you must install a rear-facing child
restraint on the front passenger seat because circumstances require you to do so, make sure the 56 indica­tor lamp is illuminated, indicating that
the front passenger front air bag is deac­tivated. Should the 56 indicator lamp not illuminate or go out while the restraint is installed, please check in­stallation. Periodically check the 56 indicator lamp while driving to make sure the 56 indicator lamp is illuminated. If the 56 indicator lamp goes out or remains out, do not transport a child on the front pas­senger seat until the system has been repaired. A child in a rear-facing child re­straint on the front passenger seat will be seriously injured or even killed if the front passenger front air bag inflates.
If you have to place a child in a
forward-facing child restraint on the front passenger seat, move the seat as far back as possible, use the proper child restraint recommended for the age, size and weight of the child, and secure child restraint with the vehicle’s seat belt according to the child seat manufacturer’s instructions.
For children larger than the typical 12-month-old child, the front passenger front air bag may or may not be activated (
page 73).
Warning! G
Infants and small children should never share a seat belt with another occupant. During an accident, they could be crushed between the occupant and seat belt.
A child’s risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and/or the child is not properly secured in the child restraint.
Children too big for a toddler restraint must ride in seats using regular seat belts. Posi­tion shoulder belt across chest and shoul­der, not face or neck. A booster seat may be necessary to achieve proper belt positioning for children over 41 lbs until they reach a height where a lap/shoulder belt fits properly without a booster.

When the child restraint is not in use, remove it from the vehicle or secure it with the seat belt to prevent the child restraint from becoming a projectile in the event of an accident.
Do not leave children unattended in the vehicle, even if the children are secured in a child restraint system. Unsupervised children in a child restraint system may use vehicle equipment and may cause an accident and/or serious personal injury.

ESP
(Electronic Stability Program)
Warning! G
The following factors increase the risk of accidents:
Excessive speed, especially in turns
Wet and slippery road surfaces
Following another vehicle too closely

®
is only
ABS
Warning! G
Do not pump the brake pedal. Use firm, steady brake pedal pressure instead. Pump­ing the brake pedal defeats the purpose of the ABS and significantly reduces braking effectiveness.
The Antilock Brake System (ABS) regulates the brake pressure so that the wheels do not lock during braking. This allows you to maintain the ability to steer your vehicle.
The ABS is functional above a speed of approximately 5 mph (8 km/h) indepen­dent of road surface conditions.
On slippery road surfaces, the ABS will respond even to light brake pressure.
The - indicator lamp in the instrument cluster (
page 28) comes on when you
switch on the ignition. It goes out when the engine is running.

Driving safety systems
Braking
At the instant one of the wheels is about to lock up, a slight pulsation can be felt in the brake pedal, indicating that the ABS is in the regulating mode.
Keep firm and steady pressure on the
brake pedal while experiencing the pulsation.
Continuous, steady brake pedal pressure yields the advantages provided by the ABS, namely braking power and the ability to steer the vehicle.
The pulsating brake pedal can be an indication of hazardous road conditions and functions as a reminder to take extra care while driving.
Emergency brake maneuver
Keep continuous full pressure on the
brake pedal.

Warning! G
The ABS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking or steering efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction avail­able on the road surface. The ABS cannot prevent accidents, including those resulting from excessive speed in turns, following an­other vehicle too closely, or hydroplaning. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ABS equipped vehicle must never be exploit­ed in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.

Driving safety systems
BAS
The Brake Assist System (BAS) operates in emergency situations. If you apply the brakes very quickly, the BAS automatically provides full brake boost, thereby poten­tially reducing the braking distance.
Apply continuous full braking pressure
until the emergency braking situation is over.
The ABS will prevent the wheels from locking.
When you release the brake pedal, the brakes function again as normal. The BAS is then deactivated.
Warning! G
If the BAS is malfunctioning, the brake sys­tem is still functioning normally, but without the additional brake boost available that BAS would normally provide in an emergen­cy braking maneuver. Therefore, the braking distance may increase.
Warning! G
The BAS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction. The BAS cannot prevent accidents, including those resulting from excessive speed in turns, fol­lowing another vehicle too closely, or hydro­planing. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of a BAS equipped vehicle must never be exploited in a reckless or danger­ous manner which could jeopardize the user’s safety or the safety of others.
®
ESP
The Electronic Stability Program (ESP®) is operational as soon as the engine is run­ning and monitors the vehicle’s traction (force of adhesive friction between the tires and the road surface) and handling.
The ESP
