!Lock the car if you wash it in an automatic
car wash. Otherwise, the vehicle might be
damaged.
!Never clean your vehicle in aTouchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
If you have your vehicle cleaned in ahigh-
pressure automatic car wash, small amounts
of water may enter the vehicle.
!Make sure that the automatic transmission
is in position Nwhen washing your vehicle in
at ow-through car wash. The vehicle could be
damagedift he transmission is in another
position.
!Make sure that:
Rthe side windows and the roof are com-
pletely closed
Rthe climate control blower is switched off
Rthe windshieldw iper switch is at position 0
The vehicle could otherwise be damaged.
You can clean the vehicle at an automatic car
wash from the very start.
Preferably clean the vehicle at automatic car
washes that use textile washing elements with-
out brushes. This prevents fine scratches from
forming on the paintwork and film.
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 windshielda nd the wiper blades. This
will prevent smears and reduce wiping noises
caused by residue on the windshield.
iVehicles with decorative film: select awash
program without hot wax at the automatic car
wash.
Washing by hand
In some countries, washing by hand is only
allowed at speciallye quipped washing bays.
Observe the legal requirements in each country.
XDo not use hot water and do not wash the
vehicle in direct sunlight.
XUse asoft sponge to clean.
XUse amild cleaning agent, such as acar
shampoo approved by Mercedes-Benz.
XThoroughly hose down the vehicle with agen-
tle jet of water.
XDo not point the water jet directly towards the
air inlet or the edges of decorative foils.
XUse plenty of water and rinse out the sponge
frequently.
XRinse the vehicle with clean water and dry
thoroughly with achamois.
XDo not let the cleaning agent dry on the paint-
work or the decorative foils.
Carefully remove all deposits of road salt as
soon as possible when driving in winter.
Powerw ashers
GWARNING
The water jet from acircular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nentsd amagedint his way may fail unexpect-
edly.T here is arisk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis componentsr eplaced imme-
diately.
!Vehicles with decorative foil: parts of your
vehicle are covered with decorative foil. Main-
tain adistance of at least 27.5 in (70 cm)
between the foil-wrappedp arts of the vehicle
and the nozzle of the high pressure cleaner.
Information aboutt he correct distance is
available from the equipment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
The water temperature of the high-pressure
cleaner must not exceed 140 °F (60 °C).
!Alwaysm aintainadistance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information aboutt he
correct distance is available from the equip-
ment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
Do not aim directly at any of the following:
Rtires
Rdoor gaps, roof gaps, joints, etc.
Relectrical components

The tire pressure monitor hasayellow warning
lamp in the instrument cluster for indicating
pressure loss or amalfunction. Whether the
warning lamp flashes or lights up indicates
whether atire pressure is too low or the tire
pressure monitor is malfunctioning:
Rif the warning lamp is lit continuously, the tire
pressure on one or more tires is significantly
too low. The tire pressure monitor is not mal- functioning.
Rif the warning lamp flashes for approximately
am inute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
In addition to the warning lamp, amessage
appears in the multifunction display.O bserve
the information on display messages
(
Ypage 196).
It may take up to ten minutes for amalfunction
of the tire pressure monitor to be indicated. A
malfunction will be indicated by the tire pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
malfunction has been rectified, the tire pressure
warning lamp goes out after afew minutes of
driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at agas station with apressure gage. The
tire pressures shown by the on-board computer
refer to those measured at sea level. At high
altitudes, the tire pressure values indicated by a pressure gage are higher than those shown by
the on-board computer. In this case, do not
reduce the tire pressures.
The operation of the tire pressure monitor can
be affected by interferenc efrom radio transmit-
ting equipment (e.g. radio headphones, two-way
radios) that may be being operated in or near the vehicle.
Checking the tire pressur eelectroni-
cally
XMake sure that the SmartKey is in position 2
(Ypage 116) in the ignition lock.
XPress the =or; button on the steering
wheel to select the Serv.menu.
XPress the9or: button to select
Tire Pressure.
XPress a.
The current tire pressure of each tire is shown
in the multifunction display. If the vehicle has been parked for over
20 minutes, the
Tire pressure will be
displayed after driving afew minutesmessage appears.
After ateach-in process, the tire pressure mon-
itor automatically detect snew wheels or new
sensors. As long as aclear allocation of the tire
pressure value to the individual wheels is not
possible, the Tire
PressureMonitorActivedisplay message is shown instead of the tire
pressure display.T he tire pressures are already
being monitored.
If an emergencys pare wheel is mounted, the
system may continue to show the tire pressure
of the wheel that has been removed for afew
minutes. Be aware that the value displayed for
the position where the emergencys pare wheel
is fitted is not the same as the current tire pres-
sure of the emergencys pare wheel.
Tire pressuremonitor warning mes-
sages
The tire pressure monitor detect sapressure
loss in one or more tires:
RIf the tire pressure monitor detect sapressure
loss in one or more tires, awarning message
is shown in the multifunction display.T he yel-
low tire pressure warning lamp then lights up.
RIf the Please Correct Tire Pressuremessage appears in the multifunction display,
the tire pressure in at least one tire is too low.
The tire pressure must be corrected when the
opportunit yarises.
RIf the Check Tiresmessage appears in the
multifunction display,t he tire pressure in at
least one tire has dropped significantly. The
tires must be checked.
RIf the WarningTireMalfunctionmessage
appears in the multifunction display,t he tire
pressure in at least one tire has dropped sud-
denly. The tires must be checked.
Observe the instructions and safety notes in the
display messages in the "Tires" section
(
Ypage 196).
If the wheel positions on the vehicle are rotated,
the tire pressures may be displayed for the
wrong positions for ashort time. This is rectified
after afew minutes of driving, and the tire pres-
sures are displayed for the correctp ositions.
