%
The yellow ABS warning
lamp is lit while the
engine is running.
ABS (Anti-lock Braking System) is deactivated due to a
malfunction. For this reason, BAS (Brake Assist), BAS PLUS,
ESP®(Electronic Stability Program), PRE-SAFE®, PRE-SAFE®
Brake, COLLISION PREVENTION ASSIST, the HOLD function, hill
start assist, crosswind driving assistance and ESP®trailer
stabilization are also deactivated, for example.
ATTENTION ASSIST is deactivated.
GWARNING
The brake system continues to function normally, but without the
functions listed above. The wheels could therefore lock if you
brake hard, for example.
The steerability and braking characteristics may be severely
affected. The braking distance in an emergency braking situation
can increase.
If ESP®is not operational, ESP®is unable to stabilize the vehicle.
There is an increased risk of skidding and an accident.
XObserve the additional display messages in the multifunction
display.
XDrive on carefully.
XVisit a qualified specialist workshop.
If the ABS control unit is faulty, there is also a possibility that other
systems, such as the navigation system or the automatic
transmission, will not be available.

Ruse in mountainous terrain or on poor road
surfaces
Rif the engine is often left idling for long
periods
Under these or similar conditions, have, for
example, the air filter, engine oil and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must
be checked more often. Further information
can be obtained at a qualified specialist
workshop, e.g. an authorized Mercedes-Benz
Center.
Driving abroad
An extensive Mercedes-Benz Service network
is also available in other countries. You can
obtain further information from any
authorized Mercedes-Benz Center.
Care
General notes
HEnvironmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible
manner.
!For cleaning your vehicle, do not use any
of the following:
Rdry, rough or hard cloths
Rabrasive cleaning agents
Rsolvents
Rcleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film.
!Do not park the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after
cleaning. Braking heats the brake discs and
the brake pads/linings, thus drying them.
The vehicle can then be parked.
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents
recommended and approved by Mercedes-
Benz.
Washing the vehicle and cleaning the
paintwork
Automatic car wash
GWARNING
Braking efficiency is reduced after washing
the vehicle. There is a risk of an accident.
After the vehicle has been washed, brake
carefully while paying attention to the traffic
conditions until full braking power is restored.
!If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes
automatically in certain situations. To
prevent damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or other similar situations:
Rwhen towing the vehicle
Rin the car wash
!Never clean your vehicle in a Touchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
!Make sure that:
Rthe side windows and the sliding sunroof
are fully closed.
Rthe ventilation/heating is switched off
(the OFF button has been pressed).
Rthe windshield wiper switch is in position
0.
Otherwise, the vehicle might be damaged.
!In car washes with a towing mechanism,
make sure that the automatic transmission
376Care
Maintenance and care

is in transmission positionN, otherwise the
vehicle could be damaged.
RVehicles with a SmartKey:
Do not remove the SmartKey from the
ignition lock. Do not open the driver's
door or front-passenger door when the
engine is switched off. Otherwise, the
automatic transmission selects park
positionPautomatically and locks the
wheels. You can prevent this by shifting
the automatic transmission toN
beforehand.
RVehicles with KEYLESS-GO:
Do not open the driver's door or front-
passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park positionP
automatically and locks the wheels.
Observe the following to make sure that the
automatic transmission stays in positionN:
XMake sure the vehicle is stationary and the
ignition is switched off.
XTurn the SmartKey to position
2(Ypage 167) in the ignition lock.
Use the SmartKey instead of the Start/
Stop button on vehicles with KEYLESS-GO.

positionN.
XRelease the brake pedal.
XRelease the electric parking brake.
XSwitch off the ignition and leave the
SmartKey in the ignition lock.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off
wax from the windshield and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the
windshield.
Washing by hand
In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements in all
countries concerned.
XDo not use hot water and do not wash the
vehicle in direct sunlight.
XUse a soft sponge to clean.
XUse a mild cleaning agent, such as a car
shampoo approved by Mercedes-Benz.
XThoroughly hose down the vehicle with a
gentle jet of water.
XDo not point the water jet directly towards
the air inlets.
XUse plenty of water and rinse out the
sponge frequently.
XRinse the vehicle with clean water and dry
thoroughly with a chamois.
XDo not let the cleaning agent dry on the
paintwork.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
Power washers
GWARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components.
Components damaged in this way may fail
unexpectedly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced
immediately.
!Always maintain a distance of at least
11.8 in (30 cm) between the vehicle and the

Information on 4MATIC vehicles
!Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised,
as doing so will damage the transmission.
If the vehicle has transmission damage or
damage to the front or rear axle, have it
transported on a transporter or trailer.
In the event of damage to the electrical
system
If the battery is defective, the automatic
transmission will be locked in positionP. To
shift the automatic transmission to position
N, you must provide power to the vehicle's
electrical system in the same way as when
jump-starting (Ypage 395).
Have the vehicle transported on a transporter
or trailer.
Recovering a vehicle that has become
stuck
!When recovering a vehicle that has
become stuck, pull it as smoothly and
evenly as possible. Excessive tractive
power could damage the vehicles.
If the drive wheels have become stuck in
loose or muddy ground, pull the vehicle out
with extreme caution, especially so if the
vehicle is loaded.
Never attempt to recover a vehicle with a
trailer attached.
Pull out the vehicle backwards, if possible
using the tracks it made when it became
stuck.
Tow-starting (emergency engine
starting)
!Vehicles with automatic transmission
must not be tow-started. You could
otherwise damage the automatic
transmission.
iYou can find information on "Jump-
starting" under (Ypage 395).
Fuses
Important safety notes
GWARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher
amperage, the electric cables could be
overloaded. This could result in a fire. There
is a risk of an accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
!For the fuse boxes in the engine
compartment and under the rear bench
seat, only use fuses with the suffix "S".
Otherwise, components or systems could
be damaged.
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the
components on the circuit and their functions
stop operating.
Blown fuses must be replaced with fuses of
the same rating, which you can recognize by
the color and value. The fuse ratings are listed
in the fuse allocation chart.
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
Before changing a fuse
