will be answered by Mercedes-Benz Customer Assistance Representatives 24 hours a day, 365 days a year.
Roadside assistance will be provided in accordance with standard program guidelines which include providing service
to the vehicle up to a reasonable distance from a paved roadway. We will make every effort to assist in a breakdown
situation, however, the accessibility of your vehicle will be determined by our authorized Mercedes-Benz Light Truck

Additional charges may be applicable for a breakdown location determined not to be a reasonably accessible roadside
location as determined by our authorized technician and tow service provider.
For additional information refer to the Mercedes-Benz Roadside Assistance Program brochure in your glove box.

If you change your address, be sure to send in the “Change of Address Notice” found in the Service and Warranty
Information Booklet, or simply call the Mercedes-Benz Customer Assistance Center (in the USA) at

We continuously strive to improve our product, and ask for your understanding that we reserve the right to make
changes in design and equipment. Therefore, information, illustrations and descriptions in this Operator’s Manual
might differ from your vehicle.
Optional equipment is also described in this manual, including operating instructions wherever necessary. Since they
are special-order items, the descriptions and illustrations herein may vary slightly from the actual equipment of your
vehicle.
If there are any equipment details that are not shown or described in this Operator’s Manual, your authorized
Mercedes-Benz Light Truck Center will be glad to inform you of correct care and operating procedures.
The Operator’s Manual and Service Booklet are important documents and should be kept with the vehicle.
Wa rn in 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 were 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, do not overload it. And, always wear your seat belts at all times. In a rollover crash, an
unbelted person is significantly more likely to die than a person wearing a seat belt.

its safe operation, we urge you to immediately contact your authorized Mercedes-Benz Light Truck

Antitheft alarm system
The indicator lamp is located in the center console.
The antitheft alarm is automatically armed or disarmed
with the remote control by locking or unlocking the
vehicle.
The antitheft alarm is armed within approximately
15 seconds after locking the vehicle with the remote
control.
A blinking lamp in the center console indicates that the
alarm is armed.

Use of the mechanical key in the front door locks does
not arm or disarm the antitheft alarm system.
The alarm sounds when unlocking the driver’s door
with the mechanical key. Cancel alarm by turning key in
steering lock to position 1, or with the remote control by
pressing button Œ or ‹.
If the vehicle battery voltage falls below 10 volts, the
alarm is automatically canceled and the antitheft alarm
system is disarmed. When the voltage is above this
value again, the antitheft alarm system is armed again.
Operation:
Once the alarm system has been armed, the turn signal
lamps will flash rapidly (approximately 3 minutes) and
the horn will sound intermittently (approximately
30 seconds) when someone:
• opens a door,
• opens the liftgate,
• opens the hood,
• breaks a window,
• attempts to raise the vehicle.
The alarm will stay on even if the activating element
(a door, for example) is immediately closed.
If the alarm stays on for more than 20 seconds, an
emergency call is initiated automatically. See Tele Aid
on page 166.
Note:
The alarm system will cycle three times when triggered.
The interior lights are automatically switched on when

Once the alarm system has been armed, the turn signal
lamps will flash rapidly and the horn will sound when
someone attempts to raise the vehicle, or breaks a
window and reaches into the passenger compartment.
The alarm will last approximately 3 minutes in the form
of rapidly flashing turn signal lamps. At the same time
the horn will sound for approximately 30 seconds. The
alarm will stay on even if the vehicle is immediately
lowered.
If the alarm stays on for more than 20 seconds, an
emergency call is initiated automatically. See Tele Aid
on page 166.

Seat belts and integrated restraint system
Your vehicle is equipped with seat belts for all seats,
emergency tensioning retractors for front and second
row outboard seat belts, dual front airbags and door
mounted side impact airbags. Their protective functions
are designed to complement one another.
Seat belts
Important!
Laws in most states and all Canadian provinces require
seat belt use.
All states and provinces require use of child restraints
that comply with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor Vehicle Safety
Standard 213.
All child restraint systems are designed to be secured in
vehicle seats by lap belts or the lap belt portion of a lapshoulder belt.
For your safety and that of your passengers we strongly
recommend their use.
Warn ing!
Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmart
which operates with the BabySmart
TM
compatible child seat,
TM
system
installed in the vehicle to deactivate the passenger
side front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury will result.
According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in back seats
and be seated in an appropriate infant or child
restraint system, which is properly secured with
the vehicle’s seat belt, fully in accordance with the
child seat manufacturer’s instructions.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints are
not properly secured in the vehicle and the child is
not properly secured in the child restraint.
Wa rn in g!
Never ride in a moving vehicle with the backrest
reclined. Sitting in an excessively reclined position
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
backrest and seat belt provide the best restraint
when the wearer is in an upright position and the
belt is properly positioned on the body.
Note:
For cleaning and care of the seat belts, see page 302.
Seat belt nonusage warning system
After starting the engine, a warning sounds and the seat
belt warning lamp < remains illuminated for
approximately 6 seconds if the driver’s seat belt is not
fastened.
Warn ing!
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 for injury or
death is lessened if you are wearing your seat belt.
Warn ing!
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.

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 airbag, front passenger airbag, front
and rear door mounted side impact airbags),
“ETR” (seat belt emergency tensioning
retractors for the outboard passenger seats
[except in the optional 3rd row seats]), and
front seat knee bolsters. The system is
designed to enhance the protection offered to
properly belted occupants in certain frontal
(front airbags) and side (side impact airbags)
impacts which exceed preset deployment
thresholds.
Techni cal
data
• Never wear the shoulder belt under your arm,
against your neck or off your shoulder. In a
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 belt is
positioned across your abdomen, it could cause
serious injuries in a crash.
• Each seat belt should never be used 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
manage impact forces. The twisted belt against
your body could cause injuries.
• Pregnant women should also use a lapshoulder 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
or on the seat. Always keep both feet on the
floor in front of the seat.

injury will result.
According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in back seats
and be seated in an appropriate infant or child
restraint system, which is properly secured with
the vehicle’s seat belt, fully in accordance with the
child seat manufacturer’s instructions.
Warn ing!
USE CHILD RESTRAINTS PROPERLY.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints are
not properly secured in the vehicle and the child is
not properly secured in the child restraint.
Children too big for child restraint systems must
ride in back seats using regular seat belts. Position
shoulder belt across chest and shoulder, not face or

Supplemental restraint system (SRS)
Airbags are intended as a supplement to seat belts.
Airbags alone cannot protect as well as airbags plus
seat belts in impacts for which the airbags were
designed to operate, and do not afford any protection
whatsoever in crashes for which the airbags are not
designed to deploy.
The SRS uses two crash severity levels (thresholds) to
activate either the Emergency Tensioning Retractor
(ETR) or front airbag or both. Activation depends on the
direction and severity of the impact exceeding the
preset thresholds and whether the seat belt is fastened.
Seat belt fastened
• first threshold exceeded: ETR activates
• second threshold exceeded: airbag also activates
Seat belt not fastened
Front seats:
• first threshold exceeded:
airbag activates, but not ETR
Rear outer seats:
• first threshold exceeded:
ETR activates
Driver, front passenger and rear outer seat systems
operate independently of each other.
Emergency tensioning retractor (ETR)
The seat belts for the outboard passenger seats (except
in the optional 3rd row seats) are equipped with
emergency tensioning retractors. These tensioning
retractors are located in each belt’s inertia reel and
become operationally ready with the key in steering
lock position 1 or 2.
The emergency tensioning retractors are designed to
activate only when the seat belts are fastened during
frontal impacts exceeding the first threshold of the SRS
and in rear impacts exceeding a preset severity level.
They remove slack from the belts in such a way that the
seat belts fit more snugly against the body restricting its
forward movement as much as possible.
In cases of other frontal impacts, angled impacts, rollovers, certain side impacts, or other accidents without
sufficient frontal or rear impact forces, the emergency
tensioning retractors will not be activated. The driver
and passengers will then be protected by the fastened
seat belts and inertia reel in the usual manner.
For seat belt and emergency tensioning retractor see
page 66.
Note:
The front passenger ETR activates only if the front
passenger seat is occupied.
Heavy objects on the front passenger seat can appear to
the “SRS” to indicate the presence of an occupant in
that seat which causes the passenger front airbag to
deploy and the ETR to activate in a crash exceeding the
appropriate threshold.

Important!
The operational readiness of the airbag system is
verified by the indicator lamp “SRS” in the instrument
cluster when turning the key in steering lock to
position 1 or 2. If no fault is detected, the lamp will go
out after approximately 5 seconds; after the lamp goes
out, the system continues to monitor the components
and circuitry of the airbag system and will indicate a
malfunction by coming on again. If the lamp does not
come on at all or if it fails to extinguish after
approximately 5 seconds or if it comes on thereafter,
a malfunction in the system has been detected.
The following system components are monitored or
undergo a self-check: crash-sensor(s), airbag ignition
circuits, front seat belt buckles, emergency tensioning
retractors, seat sensor.
Initially, when the key is turned from steering lock
position 0 to positions 1 or 2, malfunctions in the
crash-sensor are detected and indicated (the “SRS”
indicator lamp stays on longer than 5 seconds or does
not come on).
Have the system checked at your authorized
Mercedes-Benz Light Truck Center immediately.
In the operational mode, after the indicator lamp has
gone out following the initial check, interruptions or
short circuits in the airbag ignition circuit and in the
driver and front passenger seat belt buckle harnesses,
and low voltage in the entire system are detected and
indicated.
Wa rn in g!
In the event a malfunction of the “SRS” is indicated
as outlined above, the “SRS” may not be
operational. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Light Truck 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, or it might
deploy unexpectedly and unnecessarily which
could also result in injury.
Front airbags
The driver and front passenger front airbags are
designed to activate only in certain frontal impacts
exceeding a preset threshold.
The front passenger airbag deploys only if the front
passenger seat is occupied and the ü indicator lamp
in the instrument cluster is not illuminated.
Note:
Heavy objects on the front passenger seat can appear to
the “SRS” to indicate the presence of an occupant in
that seat which causes the passenger front airbag to
deploy in a crash exceeding the appropriate threshold.
Side impact airbags, window curtain airbags
Side impact airbags
The side impact airbags are designed to activate only in
certain side impacts exceeding a preset threshold. Only
the side impact airbags on the impacted side of the
vehicle deploy.
The side impact airbag for the front passenger deploys
only if the front passenger seat is occupied.

Side impact airbags operate best in conjunction with a
properly positioned and fastened seat belt.
Note:
Heavy objects on front passenger seat can appear to the
“SRS” to indicate the presence side of an occupant in
that seat which causes the side impact airbag to deploy
in a crash exceeding the appropriate threshold.
Window curtain airbags
The window curtain airbags are designed to activate
only in certain side impacts exceeding a preset
threshold. Only the head protection window curtain
airbag on the impacted side of the vehicle deploys.
Important!
Airbags are designed to activate only in certain
frontal (front airbags) impacts, or side (side impact
and head protection window curtain airbags)
impacts which exceed preset thresholds.
Only during these types of impacts, if of sufficient
severity to meet the deployment thresholds, will
they provide their supplemental protection.
The driver and passenger should always wear their
seat belts, otherwise it is not possible for the airbags
to provide their intended supplemental protection.
In cases of other frontal impacts, angled impacts,
roll-overs, other side impacts, rear collisions, or
other accidents in which the airbags are not
designed to deploy, the airbags will not be activated.
The driver and passenger will then be protected by
the fastened seat belts.
We caution you not to rely on the presence of the
airbags in order to avoid wearing your seat belt.
Wa rn in g!
Airbags are designed to reduce the potential of
injury in certain frontal (front airbags) impacts,
and side (side impact and head protection window
curtain airbags) impacts which may cause
significant injuries, however, no system available
today can totally eliminate injuries and fatalities.
The activation of the “SRS” temporarily releases a
small amount of dust from the airbags. This dust,
however, is neither injurious 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
airbag inflates, then get fresh air by opening a
window or door.
Your vehicle was originally equipped with airbags
which are designed to activate in certain impacts
exceeding a preset threshold to reduce the potential
and severity of injury. It is important to your safety
and that of your passenger that you replace deployed
airbags and repair any malfunctioning airbags to
ensure the vehicle will continue to provide crash
protection for occupants.
Warn ing!
To reduce the risk of injury when the front airbags
inflate, it is very important for the driver and front
passenger to always be in a properly seated
position and to wear their 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
ensure that it is properly positioned on your body.
Since the airbag 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 airbag. Occupants who are
unbelted, out of position or too close to the airbag
can be seriously injured by an airbag as it inflates
with great force in the blink of an eye:

• Sit properly belted in an upright position with
your back against the backrest.
• Adjust the driver’s seat as far as possible
rearward, still permitting proper operation of
vehicle controls. The distance from the center
of the driver’s breastbone to the center of the
airbag cover on the steering wheel must be at
least ten inches (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 your
authorized Mercedes-Benz Light Truck Center.
• Do not lean with 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 the driver front airbag
inflates.
• Adjust the front passenger seat as far as
possible rearward from the dashboard when
the seat is occupied.
• Occupants, especially children, should never
lean their heads in the area of the door where
the side airbag inflates. This could result in
serious injuries or death should the airbag be
triggered. Always sit upright, properly use the
seatbelts and appropriate size infant or child
restraint system.
• 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
TM
system installed in the vehicle to
TM
deactivate the passenger side front airbag
when it is properly installed. Otherwise they
will be struck by the airbag when it inflates in
a crash. If this happens, serious or fatal injury
can result.
Failure to follow these instructions can result in
severe or fatal injuries to you or other occupants.
Wa rn in g!
Accident research shows that the safest place for
children in an automobile is in the rear seat.
Should you choose to place a child 12 years old or
under in the front passenger seat of your vehicle,
you must properly use a BabySmart
restraint which will turn off the passenger side
front airbag. BabySmart
TM
will not, however, turn
TM
child
off the vehicle’s side impact airbag.
It should be noted that with respect to both front
and rear side impact airbags there is a possibility
for a side airbag related injury if occupants,
especially children, are not properly seated or
restrained when next to a side airbag 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 where the side
airbag inflates. This could result in serious
injuries or death should the side airbag be
activated; (2) always sit upright, properly use the
seat belts and use an appropriately sized infant or
child restraint system for all children 12 years old
or under; and (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 both rear door mounted side
airbags deactivated, then deactivation can be
accomplished upon your written election to do so at
your 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.

Safety guidelines for the seat belt,
emergency tensioning retractor and airbag
Wa rn in g!
• Damaged seat belts or belts that were highly
stressed in an accident must be replaced and
their anchoring points must also be checked.
Use only belts installed or supplied by an
authorized Mercedes-Benz Light Truck Center.
• Do not pass belts over sharp edges.
• Do not make any modification that could
change the effectiveness of the belts.
• Airbags and ETR’s are designed to function on
a one-time-only basis. An airbag or emergency
tensioning retractor (ETR) that was activated
must be replaced.
• 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 curtain airbag is
deployed.
• An airbag system component within the
steering wheel gets hot after the airbag has
inflated. Do not touch.
• Improper work on the system, including
incorrect installation and removal, can lead to
possible injury through an unintended
activation of the “SRS”.
• 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 etc. over the
steering wheel hub, front passenger airbag
cover, or front door trim panels, and
installation of additional electrical / electronic
equipment on or near “SRS” components and
wiring. Keep area between airbags and
occupants free of objects (e.g. packages,
purses, umbrellas, etc.).
• In addition, through improper work there is
the risk of rendering the “SRS” inoperative or
causing unintended airbag deployment. Work
on the “SRS” must therefore only be performed
by an authorized Mercedes-Benz Light Truck
Center.
• For your protection and the protection of
others, when scrapping the airbag unit or
emergency tensioning retractor, our safety
instructions must be followed. These
instructions are available at your authorized
Mercedes-Benz Light Truck Center.
• Given the considerable deployment speed and
the textile structure of the airbags, there is the
possibility of abrasions or other injuries
resulting from airbag deployment.
When you sell the vehicle we strongly urge you to give
notice to the subsequent owner that it is equipped with
an “SRS” by alerting him to the applicable section in the
Operator’s Manual.

Infant and child restraint systems
We recommend that 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 routing. Then pull shoulder belt out
completely and let it retract. During the 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.
Note:
For child seats with mounting fittings for tether
anchorages refer to page 70 (installation of infant and
child restraint systems).
Warn ing!
Never release the seat belt buckle while vehicle is
in motion, since the special seat belt retractor will
be deactivated.
Important!
The use of infant or child restraints is required by law in
all 50 states and all Canadian provinces.
Infants and small children should be seated in an
appropriate infant or child restraint system properly
secured by a lap-shoulder belt, and that complies with
U.S. Federal Motor Vehicle Safety Standard 213 and
Canadian Motor Vehicle Safety Standard 213.
A statement by the child restraint manufacturer of
compliance with this standard can be found on the
instruction label on the restraint and in the instruction
manual provided with the restraint.
When using any infant or child restraint system, be sure
to carefully read and follow all manufacturer’s
instructions for installation and use.
Please read and observe warning labels affixed to inside
of vehicle and to infant or child restraints.
Wa rn in g!
Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmart
which operates with the BabySmart
TM
compatible child seat,
TM
System
installed in the vehicle to deactivate the passenger
front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury can result.
According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in back seats
and be seated in an infant or child restraint system,
which is properly secured with the vehicle’s seat
belt, fully in accordance with the child seat
manufacturer’s instructions.
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.
Children too big for child restraint systems must
ride in back 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 from 41 lbs. to
the point where a lap/ shoulder belt fits properly
without one.
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
serious personal injury.

Outside temperature indicator (2)
The temperature sensor is located in the front bumper
area. Due to its location, the sensor can be affected by
road or engine heat during idling or slow driving. This
means that the accuracy of the displayed temperature
can only be verified by comparison to a thermometer
placed next to the sensor, not by comparison to external
displays (e.g. bank signs etc.).
Adaptation to ambient temperature takes place in steps
and depends on the prevailing driving conditions (stopand-go or moderate, constant driving) and amount of
temperature change.
Wa rn in g!
The outside temperature indicator is not designed
to serve as an Ice-Warning Device and is therefore
unsuitable for that purpose. Indicated
temperatures just above the freezing point do not
guarantee that the road surface is free of ice.
Tachometer (11)
The tachometer displays the present engine speed in
revolutions per minute (RPM).
To help protect the engine, the fuel supply is interrupted
if the engine is operated above its specified limit.

Flexible service system (FSS)
(service indicator)
The FSS permits a flexible service schedule that is
directly related to the operating conditions of the
vehicle.
The symbol 9 or ´ appears in the main odometer
field prior to the next suggested service. Depending on
operating conditions throughout the year, the next
service is calculated and displayed in days or distance
remaining.
The symbols 9 or ´ indicate the type of service
to be performed:
9 Service A
´ Service B
The message is displayed for approximately 10 seconds
when turning the key in steering lock to position 2, or
while driving when reaching the service warning
threshold.
The message can be canceled manually by pressing
button (1).
The next service due date is displayed either in days or
in miles, depending on your driving style.
Once the suggested term has passed, the symbol 9
or ´ plus message, preceded by a – (minus symbol)
blinks every time when turning the key in steering lock
to position 2.
Calling up service indicator manually:
Activate the instrument cluster, see page 86.
Within 1 second press button (1) twice to call up the
FSS display for approximately 10 seconds.
Important!
The FSS indicator is not an engine oil level indicator.
See page 96 for engine oil level indicator.
Notes:
When disconnecting vehicle battery for one or more
days at a time, such days will not be counted. Any such
days not counted by the FSS can be added by your
Mercedes-Benz Light Truck Center.
The interval between services is determined by the type
of driving for which the vehicle is used. For example,
driving at extreme speeds, and cold starts combined
with short distance driving in which the engine does not
reach normal operating temperature, reduce the interval
between services.
Following a completed A or B service the MercedesBenz Light Truck Center sets the counter mileage to
10 000 miles (Canada: 15 000 km).
The counter can also be set by any individual. To do so:
1. Turn the key in steering lock to position 2.
2. Immediately press button (1) twice within one
second.
3. The present status for days or distance is displayed.
Within 10 seconds turn key in steering lock to
position 0.
4. Press and hold button (1), while turning key in
steering lock to position 2 again. The present status
for days or distance is displayed once more.
Continue to hold button (1).
After approximately 10 seconds a signal sounds, and
the display shows 10 000 miles (Canada: 15 000 km)
for approximately 10 seconds.
5. Release button (1).
If the FSS counter was inadvertently reset, have it
corrected at a Mercedes-Benz Light Truck Center.
Note:
However you choose to set your reference numbers, the
scheduled services as posted in the Service Booklet
must be followed to properly care for your vehicle.
