Sport Utility Vehicle

Warning!
G
This Sport Utility Vehicle is designed for both on-road and off-road use. It can go places and perform tasks for which conventional 2-wheel drive passenger cars are not intended. This vehicle will handle and maneuver differently from conventional passenger cars in driving conditions which may occur on streets, highways and off-road use.
This vehicle has a higher ground clearance and a higher center of gravity than many passenger cars. As with other vehicles of this type, if you make sharp turns at excessive speeds or abrupt maneuvers, the vehicle may roll over or may go out of control and crash. Utility vehicles have a significantly higher rollover rate than other types of vehicles. Failure to operate this vehicle safely may result in an accident, rollover of the vehicle, and severe or fatal injury.
Before you start to drive this vehicle, read the Operator’s Manual. Take time to become familiar with the driving characteristics of this vehicle. Be sure you are familiar with all vehicle controls. Learn how your vehicle handles on different road surfaces. Do not attempt sharp turns at excessive speeds or abrupt maneuvers or other unsafe driving actions that can cause loss of vehicle control. When driving off-road or working the vehicle hard, do not overload it. And, always wear

SRS indicator lamp

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 SRS indicator lamp 6 in the instrument cluster comes on when the ignition is switched on. It goes out no later than a few seconds after the engine has been started.
The SRS components are in operational readiness when the SRS indicator lamp 6 is not lit while the engine is running.
Although the systems are independent, their protective functions work in conjunction with each other.

For your safety, we strongly recommend that you contact an authorized Mercedes-Benz Center immediately to have the system checked. Otherwise the SRS may not be activated when needed in an accident, which could result in serious or fatal injury. The SRS might also deploy unexpectedly and unnecessarily which could also result in injury as well.
In addition, improper 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 an authorized Mercedes-Benz Center. USA only: 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 potential of injury and fatality in certain
R
frontal impacts (front air bags)
R
side impacts (side impact air bags and window curtain air bags)
R
rollovers (window curtain air bags)
However, no system available today can completely eliminate injuries and fatalities.
Deployment of the air bags temporarily releases a small amount of dust from the air bags. This dust, however, is neither harmful to your health, nor does it indicate a fire in the vehicle. The dust might cause some temporary 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.
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 belt.
For maximum protection in the event of a collision always be in normal seated position with your back against the seat 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 position and correct positioning of the hands on the steering wheel will help to keep you at a safe distance from the air bag. Occupants who are not wearing their seat belt, are not seated properly or are too close to the air bag can be seriously injured or killed by an air bag as it inflates with great force instantaneously:
R
Sit with the seat belt properly fastened in a position that is as upright as possible with your back against the seat backrest.
R
Move the driver’s seat as far back as possible, still permitting proper operation of vehicle controls. The distance from the center of the driver’s chest to the center of the air bag cover on the steering wheel must be at least 10 inches (25 cm) or more. You should be able to accomplish this by adjusting the seat and steering wheel. If
Safety and security
Z
Page 40
Occupant safety
38
you have any difficulties, please contact an authorized Mercedes-Benz Center.
R
Do not lean your head or chest close to the steering wheel or dashboard.
R
Keep hands on the outside of the steering wheel rim. Placing hands and arms inside the rim can increase the risk and potential severity of hand/arm injury when the driver front air bag inflates.
R
Adjust the front passenger seat as far as possible rearward from the dashboard when the seat is occupied.
R
Occupants, especially children, should
Safety and security
never place their bodies or lean their heads in the area of the door where the side impact air bag inflates. This could result in serious injuries or death should the side impact air bag be deployed. Always sit as upright as possible, wear the seat belt properly and use an appropriately sized infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child.
R
Canada only: Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized BabySmart™ compatible child seat, which operates with the BabySmart™ air bag deactivation system installed in the vehicle to deactivate the front passenger front air bag when it is installed properly. Otherwise they will be struck by the air bag when it inflates in a crash. If this happens, serious or fatal injury will result.
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.
Warning!
G
Accident research shows that the safest place for children in an automobile is in a rear seat.
There is a possibility for a side impact air bag­related injury if occupants, especially children, are not properly seated or restrained when next to a 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,
wear the seat belt properly, 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 certain
R
frontal impacts (front air bags)
R
side impacts (side impact and window curtain air bags) if the system determines the need for air bag deployment
R
rollovers (window curtain air bags)
Only in the event of such a situation will they provide their supplemental protection.
The driver and passengers 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 passengers 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.
Air bags are not a substitute for seat belts. Always wear your seat belt, regardless of whether or not your vehicle is equipped with air bags.
It is important to your safety and that of your passengers to have deployed air bags replaced and to have any malfunctioning air
Page 41
Occupant safety
39
bags repaired. This will help to make sure the air bags will continue to provide supplemental crash protection for occupants.
Safety guidelines for the seat belt, Emergency Tensioning Device (ETD) and air bag
Warning!
G
R
Damaged seat belts or seat belts that have been subjected to stress in an accident must be replaced. Their anchoring points must also be checked. Only use seat belts installed or supplied by an authorized Mercedes-Benz Center.
R
Air bags and pyrotechnic 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
www.dtsc.ca.gov/HazardousWaste/ Perchlorate/index.cfm.
R
Air bags and ETDs are designed to function on a one-time-only basis. An air bag or ETD that has deployed must be replaced.
R
Do not pass seat belts over sharp edges. They could tear.
R
Do not make any modification that could change the effectiveness of the seat belts.
R
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.
R
No modifications of any kind may be made to any components or wiring of the SRS.
R
Do no change or remove any component or part of the SRS.
R
Do not install additional trim material, seat covers, badges, etc. over the steering wheel hub, front passenger front air bag cover, outboard sides of the seat backrests, door trim panels, or door frame trims.
R
Do not install additional electrical/ electronic equipment on or near SRS components and wiring.
R
Keep area between air bags and occupants free of objects (e.g. packages, purses, umbrellas, etc.).
R
Do not hang items such as coat hangers from the coat hooks or handles over the door. These items may be thrown around in the vehicle and cause head and other injuries when the window curtain air bag is deployed.
R
Air bag system components will be hot after an air bag has inflated. Do not touch them.
R
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.
R
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.
R
For your protection and the protection of others, when scrapping the air bag unit or ETD, our safety instructions must be followed. These instructions are available from any authorized Mercedes-Benz Center.
R
Given the considerable deployment speed, required inflation volume, and the material of the air bags, there is the possibility of abrasions or other, potentially more serious injuries resulting from air bag deployment.
If you sell your vehicle, we strongly recommend that you inform the subsequent owner that the vehicle is equipped with SRS. Also refer them to the applicable section in the Operator’s Manual.

The front air bags in this vehicle have been designed to inflate in two stages. This allows the air bags to have different rates of inflation. The rate of inflation is based on the vehicle deceleration rate as assessed by the air bag control unit.
Vehicles with OCS, USA only: The front passenger front air bag deployment is additionally influenced by the passenger’s weight category as identified by the Occupant Classification System (OCS) (Y page 42).
Vehicles with OCS, USA only: The lighter the front passenger-side occupant, the higher the vehicle deceleration rate required for second stage inflation of the front passenger front air bag.
The air bags will not deploy in impacts which do not exceed the system’s preset deployment thresholds. You will then be protected by the fastened seat belts.
The front air bags will not deploy in the event of a rollover unless the vehicle’s rate of longitudinal deceleration or acceleration exceeds the preset deployment threshold for the front air bags.
The front passenger front air bag will only be deployed if
R
vehicles with OCS, USA only: the system, based on OCS weight sensor readings, detects that the front passenger seat is occupied

!
Vehicles with BabySmart™ air bag deactivation system (Canada only): Do not place objects heavier than 20 lb (9 kg) on the front passenger seat. This could cause the front or side impact air bag on the front passenger side to deploy in a crash which exceeds the system’s deployment threshold.
Side impact air bags
Observe Safety notes, see page 37.
G
Warning!
G
The pressure sensors for side impact air bag control are located in the doors. Do not modify any components of the doors or door trim panels including, for example, the addition of door speakers.
Improper repair work on the doors or the modification or addition of components to the doors create a risk of rendering the side impact air bags inoperative or causing unintended air bag deployment. Work on the doors must therefore only be performed by

Occupant Classification System

Safety and security
The Occupant Classification System (OCS) is standard equipment in USA.
The OCS activates or deactivates the front passenger front air bag automatically. The respective status is based on the classified occupant weight category determined by weight sensor readings from the front passenger seat.
The system does not deactivate
R
the front passenger side impact air bag
R
the window curtain air bag
R
the Emergency Tensioning Devices (ETDs)
To be classified correctly, the front passenger must sit
R
with the seat belt properly fastened
R
in a position that is as upright as possible with the back against the seat backrest
R
with the feet on the floor
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 the trim cover and 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 the driver and the front passenger should always use the 45 indicator lamp as an indication of whether or not the front passenger is properly positioned.
Warning!
G
If the 45 indicator lamp illuminates when an adult or someone larger than a small individual is in the front passenger seat, have the front passenger reposition himself or herself in the seat until the 45 indicator lamp goes out.
In the event of a collision, the air bag control unit will not allow front passenger front air bag deployment when the OCS has classified the front passenger seat occupant as weighting as much as or less than a typical 12-month­old child in a standard child restraint or if the front passenger seat is classified as being empty.
When the OCS senses that the front passenger seat occupant is classified as being up to or less than the weight of a typical 12-month-old child in a standard child restraint, the 45 indicator lamp will illuminate when the engine is started and remain illuminated, indicating that the front passenger front air bag is deactivated.
When the OCS senses that the front passenger seat is classified as being empty, the 45 indicator lamp will illuminate when the engine is started and remain illuminated, indicating that the front passenger front air bag is deactivated.
When the OCS senses that the front passenger seat occupant is classified as being heavier than the weight of a typical 12-month-old child seated in a standard child restraint or as being a small individual (such as a young teenager or a small adult), the 45 indicator lamp will illuminate for approximately 6 seconds when the engine is started and then, depending on occupant weight sensor readings from the seat, remain

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 restraint, toddler restraint, or booster seat 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, or lower anchors and top tether strap, fully in accordance with the child seat manufacturer’s instructions.
Occupants, especially children, should always sit as upright as possible, wear the seat belt properly 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:
R
Your vehicle is equipped with air bag technology designed to deactivate 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.
R
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 a backseat.
R
If you must install a rear-facing child restraint on the front passenger seat because circumstances require you to do so, make sure the 45 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated. Should the 45 indicator lamp not

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-month­old child, the front passenger front air bag may or may not be activated.
Deployment of the driver front air bag does not mean that the front passenger front air bag also should have deployed.
The OCS may have determined
R
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 of which are 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
R
that the seat was occupied by a small individual (such as a young teenager or a small adult) or a child who weighs more than the weight of a typical 12-month-old child in a standard child restraint – both of which are 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

Warning!
G
If the red SRS indicator lamp 6 in the instrument cluster and the 45 indicator lamp are lit at the same time, there is a malfunction in the OCS. The front passenger front air bag will be deactivated in this case. Have the system checked by qualified technicians as soon as possible. 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:
R
Sit with the seat belt properly fastened in a position that is as upright as possible with your back against the seat backrest.
R
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

45
approximate the occupant’s weight category.
R
Read and observe all warnings in this chapter.
OCS Self-test
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 45 indicator lamp illuminates. If an adult occupant is properly sitting on the front passenger seat and the system classifies the occupant as an adult, the 45 indicator lamp will illuminate and go out after approximately 6 seconds.
If the seat is not occupied and the system classifies the front passenger seat as being empty, the 45 indicator lamp will illuminate and not go out.
Warning!
G
If the 45 indicator lamp does not illuminate, the system is not functioning. You must contact an authorized Mercedes-Benz Center before seating any child on the front passenger seat.
For more information, see the “Practical hints” section (Y page 298).
Warning!
G
Never place anything between seat cushion and child seat (e.g. pillow), since it reduces the effectiveness of the OCS. The bottom and back of the child seat must make full contact with the passenger seat cushion and backrest.
If necessary, adjust the tilt of the passenger seat backrest.
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.

Warning!
G
The BabySmart™ air bag deactivation system will ONLY work with a special child seat designed to operate with it. It will not work with child seats which are not BabySmart™ compatible.
Never place anything between seat cushion and child seat (e.g. pillow), since it reduces the effectiveness off the BabySmart™ air bag deactivation system. The bottom of the child seat must make full contact with the front passenger seat cushion. An incorrectly mounted child seat could cause injuries to the child in case of an accident, instead of protecting the child.
Follow the manufacturer’s instructions for installation of special child seats.

Seat belts

Safety notes
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.
i
See “Children in the vehicle” (Y page 53) for information on
R
infants and children traveling with you in the vehicle
R
restraint systems for infants and children
Warning!
G
Always fasten your seat belt before driving off. Always make sure all of your passengers are properly restrained. You and your passengers should always wear seat belts.
Failure to wear and properly fasten and position your seat belt greatly increases your risk of injuries and their likely severity in an accident.
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. The air bags can only protect as intended if the occupants are properly wearing their seat belts.
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 seat belt would apply force at the abdomen or neck. That could cause serious or even fatal injuries. The seat backrest and

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 have
Safety and security
been subjected to stress in an accident must be replaced. Also, the seat belt anchoring points must 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.
Proper use of seat belts
Warning!
G
USE SEAT BELTS PROPERLY
R
Seat belts can only protect 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.
R
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 front air bag, front passenger front air bag, side impact air bags, window curtain air bags for door windows), Emergency Tensioning Devices (ETDs), seat belt force limiters, 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 ETDs) and side (side impact air bags, window curtain air bags, and ETDs) impacts which exceed preset deployment thresholds and in certain rollovers (window curtain air bags and ETDs).
R
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 seat belt would also apply too much force to the ribs or abdomen, which could severely injure internal organs such as your liver or spleen.
Adjust the seat belt so that the shoulder section 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 seat belt under your arm. For this purpose, you can adjust the height of the seat belt outlet.
R
Position the lap belt as low as possible on your hips and not across the abdomen. If the lap belt is positioned across your abdomen, it could cause serious injuries in a crash.
R
Never wear seat belts over rigid or breakable objects in or on your clothing, such as eyeglasses, pens, keys etc., as these might cause injuries.
R
Make sure the seat belt is always fitted snugly. Take special care of this when wearing loose clothing.
R
Never use a seat belt for more than one person at a time. Do not fasten a seat belt
Page 51

49
around a person and another person or other objects at the same time.
R
Seat belts should not be worn twisted. In a crash, you would not have the full width of the seat belt to distribute impact forces. The twisted seat belt against your body could cause injuries.
R
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.
R
Place the seat backrest in a position that is as upright as possible.
R
Check your seat belt during travel to make sure it is properly positioned.
R
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.
R
When using a seat belt to secure infant restraints, toddler restraints, or children in booster seats, always follow the child seat manufacturer’s instructions.
children 12 years old and under must be seated and properly secured in an appropriately sized 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.
Warning!
G
Vehicles with BabySmart™ air bag deactivation system, Canada only: Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized BabySmart™ compatible child seat, which operates with the BabySmart™ system installed in the vehicle to deactivate the front passenger front air bag when it is installed properly. Otherwise they will be struck by the air bag when it inflates in a crash. If this happens, serious or fatal injury will result.

R
the seat belt telltale 7 remains illuminated for as long as either the driver’s or front passenger’s seat belt is not fastened.
R
and if the vehicle speed once exceeds 15 mph (25 km/h), the seat belt telltale 7 starts flashing and a warning chime sounds with increasing intensity for a maximum of 60 seconds or until the driver’s and front passenger’s seat belt are fastened.
If you and/or your passenger release the seat belt during driving, the seat belt telltale 7 starts flashing and the 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 7 stops flashing but continues to be illuminated.
After a vehicle standstill, the warning chime is reactivated and the seat belt telltale 7 is flashing again if the vehicle speed once exceeds 15 mph (25 km/h).
The seat belt telltale 7 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 front door is opened.
For more information, see “Practical hints” (Y page 292).
Emergency Tensioning Device (ETD), seat belt force limiter
The seat belts for the front seats and rear outer seats are equipped with ETDs and seat belt force limiters.
The ETDs are designed to activate in the following cases:
R
in frontal or rear-end impacts exceeding the system’s preset deployment threshold
R
in side impacts exceeding the system’s preset deployment threshold on the far side of the impact
R
in certain vehicle rollovers
R
if the restraint systems are operational and functioning correctly, see “SRS indicator lamp” (Y page 36)
The ETDs for the front seats will only activate if the front seat belts are fastened (latch plate properly inserted into buckle).
The ETDs for the rear outer seats will activate with or without the respective seat belts fastened.
In an impact, the ETDs remove slack from the seat belts in such a way that the seat belts fit more snugly against the body. Seat belt force limiters, when activated, are employed to help reduce the peak force exerted by the seat belts on occupants during a crash.

The use of infant or child restraints is required by law in all 50 states, the District of Columbia, the U.S. territories and all Canadian provinces.
Infants and small children should be seated in an appropriate infant or child restraint system. They must be properly secured in accordance with the manufacturer’s instructions for the child restraint. All infant or child restraint systems must comply 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 restraint, toddler restraint, or booster seat, make 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 restraint, toddler restraint, or booster seat 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, or lower anchors and top tether strap, fully in accordance with the child seat manufacturer’s instructions.
Occupants, especially children, should always sit as upright as possible, wear the seat belt properly 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:
R
USA only: Your vehicle is equipped with air bag technology designed to deactivate 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.
R
USA only: For children larger than the typical 12-month-old child, the front passenger front air bag may or may not be activated. Always make sure the 45 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated.
R
Canada only: Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized BabySmart™ compatible child seat, which operates with the BabySmart™ system installed in the vehicle to deactivate the front passenger front air bag when it is installed properly. Otherwise they will be struck by the air bag when it inflates in a crash. If this happens, serious or fatal injury will result.
R
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 a backseat.

R
If you must install a rear-facing child restraint on the front passenger seat because circumstances require you to do so, make sure the 45 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated. Should the 45 indicator lamp not illuminate or go out while the restraint is installed, please check installation. Periodically check the 45 indicator lamp while driving to make sure the 45 indicator lamp is illuminated. If the 45 indicator lamp goes out or remains out, do not transport a child on the
Safety and security
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.
R
If you have to place a child in a forward­facing 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.
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 seat belt positioning for children over 41 lb (18 kg) 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.

Safety notes
Warning!
G
The following factors increase the risk of accidents:
R
Excessive speed, especially in turns
R
Wet and slippery road surfaces
R
Following another vehicle too closely
The driving safety systems described in this section cannot reduce these risks or prevent
Safety and security
the natural laws of physics from acting on the vehicle. They cannot increase braking or steering efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction afforded.
Only a safe, attentive, and skillful driver can prevent accidents.
The capabilities of a vehicle equipped with the driving safety systems described in this section must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.
Always adjust your driving style to the prevailing road and weather conditions and keep a safe distance to other road users and objects on the street.
If a driving system malfunctions, other driving safety systems may also switch off. Observe indicator and warning lamps that may come on as well as messages in the multifunction display that may appear.
ABS
X
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 malfunctions, the brake system still functions, but without the additional brake boost available that the BAS would normally provide in an emergency braking maneuver. Therefore, the braking distance may increase.
BAS
Observe Safety notes, see page 60.
G
The Brake Assist System (BAS) operates in emergency situations. If you apply the brakes very quickly, the BAS provides full brake boost automatically, thereby potentially reducing the braking distance.
X
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!

The Brake Assist System (BAS) operates in emergency situations. If you apply the brakes very quickly, the BAS provides full brake boost automatically, thereby potentially reducing the braking distance.
EBP
Observe Safety notes, see page 60.
G
The Electronic Brake Proportioning (EBP) enhances braking effectiveness by allowing the rear brakes to supply a greater proportion
Page 63
Driving safety systems
61
of the braking effort in straight-line braking without a loss of vehicle stability.
Warning!
G
If the EBP malfunctions, the brake system will still function with full brake boost. However, the rear wheels could lock up during emergency braking situations, for example. You could lose control of the vehicle and cause an accident.
Adapt your driving style to the changed driving characteristics.
®
ESP
Observe Safety notes, see page 60.
G
The Electronic Stability Program (ESP®) is operational as soon as the engine is running. It monitors the vehicle’s traction (force of adhesive friction between the tires and the road surface) and handling.
The ESP® recognizes that the vehicle deviates from the direction of travel as intended by the driver. By applying brakes to individual wheels and by limiting the engine output, the ESP® works to stabilize the vehicle. The ESP® is especially useful while driving off and on wet or slippery road surfaces. The ESP
®
also stabilizes the vehicle during braking and steering maneuvers.
The ESP® warning lamp d in the instrument cluster comes on when you switch on the ignition. It goes out when the engine is running.
The ESP® warning lamp d in the instrument cluster flashes when the ESP® is
engaged.
Warning!
G
Never switch off the ESP® when you see the ESP® warning lamp d flashing in the instrument cluster. In this case proceed as follows:
R
When driving off, apply as little throttle as possible.
R
While driving, ease up on the accelerator pedal.
R
Adapt your speed and driving style to the prevailing road conditions.
Failure to observe these guidelines could cause the vehicle to skid. The ESP® cannot prevent accidents resulting from excessive speed.
!
Vehicles with 4MATIC: Only conduct operational or performance tests on a two-axle dynamometer. If such tests are necessary, contact an authorized Mercedes-Benz Center. You could otherwise seriously damage the brake system or the transfer case which is not covered by the Mercedes-Benz Limited Warranty.
!
Because the ESP® operates automatically, the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS-GO start/stop button in position 0 or 1) when
R
the parking brake is being tested on a brake test dynamometer
R
towing the vehicle with the front or rear axle raised (not permissible for vehicles with 4MATIC)
Active braking action through the ESP may otherwise seriously damage the brake system which is not covered by the Mercedes-Benz Limited Warranty.

as specified in the “Technical data” section of this Operator’s Manual.
i
The cruise control switches off
automatically when the ESP® engages.
Electronic Traction System (ETS/4-ETS)
Observe Safety notes, see page 60.
G
The ETS (Electronic Traction System) and 4-ETS (four-wheel Electronic Traction System, vehicles with 4MATIC only) are components of the ESP®. The ETS/4-ETS improves the vehicle’s ability to utilize
Safety and security
available traction, especially under slippery road conditions by applying the brakes to a spinning wheel. Vehicles with 4MATIC also transfer more power to the wheel(s) with traction.
When you switch off the ESP®, the ETS/4-ETS is still enabled.
Switching off the ESP
Warning!
G
The ESP® should not be switched off during normal driving other than in the circumstances described below. Disabling the system will reduce vehicle stability in driving maneuvers.
Do not switch off the ESP® when a spare wheel is mounted.
®
anymore. Otherwise the ESP® will not stabilize the vehicle when it is starting to skid or a wheel is spinning.
When you switch off the ESP®,
R
the ESP® does not stabilize the vehicle
R
the engine output is not limited, which allows the drive wheels to spin and thus cut into surfaces for better grip
R
the ETS/4-ETS will still apply the brakes to a spinning wheel
R
the ESP® continues to operate when you are braking
R
the cruise control cannot be activated
R
the cruise control switches off if activated
i
When the ESP® is switched off and one or
more drive wheels are spinning, the ESP warning lamp d in the instrument
cluster flashes. However, the ESP® will then not stabilize the vehicle.
®
To improve the vehicle’s traction, switch off the ESP®. This allows the drive wheels to spin and thus cut into surfaces for better grip, for example
R
when driving with snow chains
R
in deep snow
R
in sand or gravel
Warning!
G
Switch on the ESP® immediately if the aforementioned circumstances do not apply
X
With the engine running, press ESP switch : until the ESP® warning lamp d in the instrument cluster comes on. The ESP® is switched off.
Warning!
G
When the ESP® warning lamp d is
illuminated continuously, the ESP® is switched off or is not operational due to a malfunction. Vehicle stability in standard driving maneuvers is reduced.

Avoid spinning of a drive wheel for an extended period with the ESP® switched off. This may cause serious damage to the drivetrain which is not covered by the Mercedes-Benz Limited Warranty.
Switching on the ESP
X
Press ESP® switch : until the ESP
®
®
warning lamp d in the instrument cluster goes out. You are now again in normal driving mode with the ESP® switched on.
ESP® trailer stabilization
If the trailer you are towing should begin to sway, the rig can only be stabilized by immediately applying the brakes hard. Steering during this maneuver will not help to stabilize the rig.
The ESP® will assist you in such situations. The ESP® recognizes when the trailer starts swaying.It will apply the brakes and limit engine output and thus allow the vehicle­trailer combination to stabilize.
The ESP® trailer stabilization is functional at vehicle speeds above approximately 40 mph (65 km/h) when the ESP® is switched on.
Warning!
G
The system will not be able to assist when the trailer jackknifes
R
if the ESP® has switched off due to a malfunction

Warning!
G
Controls in detail
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 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 seat belt would apply force at the abdomen or neck. That could cause serious or fatal injuries. The seat backrest and seat belts provide the best restraint when the wearer is in a position that is as upright as possible and seat 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:
R
Adjust the seat backrest until your arms are slightly angled when holding the steering wheel.
R
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 the controls properly.
R
Adjust the head restraint so that it is as close to the head as possible. The center of the head restraint must support the back of the head at eye level.
R
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
The power seats can be operated at any time. Therefore, do not leave children unattended in the vehicle, or with access to an unlocked vehicle. A child’s unsupervised access to a vehicle could result in an accident and/or serious personal injury.
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 appropriately sized 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.
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.
Page 81
Do not drive the vehicle without the seat head restraints. Head restraints are intended to help reduce injuries during an accident.

Safety notes

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 under the pedals. You could then no longer brake or accelerate. This could lead to accidents and injury.
Warning!
G
With the engine not running, there is no power assistance for the brake and steering systems. In this case, it is important to keep in mind that a considerably higher degree of effort is necessary to brake and steer the vehicle. Adapt your driving accordingly.

Starting the engine

Warning!
G
Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide (CO), and inhaling it can cause unconsciousness and possible death.
Do not run the engine in confined areas (such as a garage) which are not properly ventilated. If you think that exhaust gas fumes are entering the vehicle while driving, have the cause determined and corrected immediately. If you must drive under these conditions, drive only with at least one window fully open at all times.
