!NThe yellow ABS warning lamp is lit while the engine is running.
ABS (Anti-lock Braking System) is deactivated due to a malfunction.
Other driving systems and driving safety systems may also malfunction.
In addition, the ÷andå warning lamps may light up in the instrument
cluster.
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 immediately.
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.

To avoid damage to the vehicle, deactivate
Distance Pilot DISTRONIC and the HOLD
function in the following or 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.
Rthat the blower of the ventilation/heating
system is switched off (OFF button has
been pressed).
Rthe windshield wiper switch is at position
g.
The vehicle may otherwise be damaged.
!In car washes with a towing mechanism,
make sure that the automatic transmission is
in transmission position i; otherwise, the
vehicle could be damaged.
RVehicles with a SmartKey:
Do not remove the SmartKey from the igni-
tion lock. Do not open the driver's door or
front-passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park position jauto-
matically and locks the wheels. You can
prevent this by shifting the automatic trans-
mission to ibeforehand.
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 position jauto-
matically and locks the wheels.
Observe the following to make sure that the
automatic transmission stays in position i:
XMake sure the vehicle is stationary and the
ignition is switched off.
XTurn the SmartKey to position in the ignition
lock2(Ypage 135).
Use the SmartKey instead of the Start/Stop
button on vehicles with KEYLESS-GO.
XDepress and hold the brake pedal.
XShift the automatic transmission to position
i.
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 t
he 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 gen-
tle 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 paint-
work.
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. Compo-
nents damaged in this way may fail unexpect-
edly. 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 imme-
diately.

Towing and tow-starting
Important safety notes
Plug-in hybrid: be sure to read the separate
Operator's Manual. You could otherwise fail to
recognize dangers, e.g. due to high voltage.
GWARNING
Functions relevant to safety are restricted or
no longer available if:
Rthe engine is not running.
Rthe brake system or the power steering is
malfunctioning.
Rthere is a malfunction in the voltage supply or the vehicle's electrical system.
If your vehicle is being towed, much more
force may be necessary to steer or brake.
There is a risk of an accident.
In such cases, use a tow bar. Before towing,
make sure that the steering moves freely.
GWARNING
When towing or tow-starting another vehicle
and its weight is greater than the permissible
gross weight of your vehicle, the:
Rthe towing eye could detach itself
Rthe vehicle/trailer combination could roll-
over.
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the per- missible gross weight of your vehicle.
Details on the permissible gross vehicle weight
of your vehicle can be found on the vehicle iden-
tification plate (
Ypage 382).
!When Active Brake Assist, Distance Pilot
DISTRONIC or the HOLD function is activated,
the vehicle brakes automatically in certain
situations. To avoid damage to the vehicle, deactivate
these systems in the following or similar sit-
uations:
Rwhen towing the vehicle
Rin the car wash
!Make sure that the electric parking brake is
released. If the electric parking brake is faulty,
visit a qualified specialist workshop.
!Only secure the tow rope or tow bar at the
towing eyes, or the trailer tow hitch, if availa-
ble. You could otherwise damage the vehicle.
!Observe the following points when towing
with a tow rope:
RSecure the tow rope on the same side on
both vehicles.
RMake sure that the tow rope is not longer
than legally permitted. Mark the tow rope in
the middle, e.g. with a white c
loth
(11.8 x 11.8 in). This will make other road
users aware that a vehicle is being towed.
ROnly secure the tow cable to the towing
eyes or, if available, to the trailer tow hitch.
RObserve the brake lamps of the towing
vehicle while driving. Always maintain a dis-
tance a distance so that the tow rope does not sag.
RDo not use steel cables or chains to tow
your vehicle. You could otherwise damage
the vehicle.
!Do not use the trailer tow hitch for recovery
or towing. Do not use the towing eye for
recovery. this could damage the vehicle. If in
doubt, have the vehicle recovered using a
crane.
!When towing, pull away slowly and
smoothly. Pull the towed vehicle as straight as
possible and not at an acute angle. Excessive
tractive power could damage the vehicles.
When towing, it is preferable to use a rigid tow-
ing bar as opposed to a tow rope. A rigid towing bar helps to keep the tractive power low.
!When towing away vehicles with KEYLESS-
GO, use the key instead of the Start/Stop
button. The automatic transmission may oth-
erwise shift to position jwhen you open the
