258Features
Stowage and features

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 clean-
ing. 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 rec-
ommended 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 the HOLD function is activated, the vehi-
cle brakes automatically in certain situa-
tions.
To prevent damage to the vehicle, deacti-
vate 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.
!When washing your vehicle in a tow-
through car wash, make sure that the selec- tor lever is in position N, otherwise the
vehicle could be damaged.
!Make sure that:
Rthe side windows are fully closed.
Rthe ventilation/heating is switched off
(the OFF button has been pressed/the
airflow control is set to position 0).
Rthe windshield wiper switch is at position
0.
The vehicle may otherwise be damaged.
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 wind-
shield.
Washing by hand
In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements in each coun- try.
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 towardsthe air inlet.
XUse plenty of water and rinse out the
sponge frequently.

Important safety notes
GWARNING
Functions relevant to safety are restricted or
no longer available if:
Rthe ignition is switched off
Rthe brake system or the power steering is
malfunctioning
Rthere is a malfunction in the power 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
You can no longer steer the vehicle if the
steering wheel lock has been engaged. There
is a risk of an accident.
Always switch off the ignition when towing the
vehicle with a tow cable or a tow bar.
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 identification plate (
Ypage 334).
!When COLLISION PREVENTION ASSIST

be damaged.
!Observe the following points when towing
with a tow rope:
RSecure the tow rope on the same side on
both vehicles.
REnsure that the t ow cable is not longer
than legally permitted. Mark the tow
cable in the middle, e.g. with a white

towed.
ROnly secure the tow cable to the towing
eye.
RObserve the brake lamps of the towing
vehicle while driving. Always maintain a
distance so that the tow rope does not
sag.

age the vehicle.
!Do not use the towing eyes for recovery
purposes as this could damage the vehicle. If in doubt, recover the vehicle with a crane.
294Towing
Breakdown assistance

!When towing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles could be damaged.
!The vehicle can be towed a maximum of
30 miles (50km). The towing speed of
30 mph (50km/h) must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the front axle must be
raised or the entire vehicle raised and
transported.
!Do not tow with sling-type equipment.
This could damage the vehicle.
!To tow vehicles with KEYLESS-GO, use
the SmartKey instead of the Start/Stop
button. The transmission may otherwise
shift to position Pwhen you open the driv-
er's or front-passenger door, which could
damage the transmission.
Observe the legal requirements for the rele-
vant countries when towing away.
Make sure that no charging cable is plugged
in. The parking lock cannot be released if a
charging cable is plugged in.
It is better to have the vehicle transported
