!Make sure that the automatic car wash is
suitable for the size of the vehicle. Fold in the
exterior mirrors before the vehicle is washed.
The exterior mirrors could otherwise be dam-
aged.
!Make sure that the automatic transmission
is in position Nwhen washing your vehicle in
a tow-through car wash. The vehicle could be
damaged if the transmission is in another
position.
!Make sure that:
Rthe side windows and sliding sunroof are
closed completely.
Rthe blower for the ventilation/heating is
switched off (airflow control is turned to
position 0/the à andÁ buttons are
switched off).
Rthe windshield wiper switch is at position 0.
The vehicle could 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 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.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
When washing the vehicle underbody, also clean the inside of the wheels.
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.
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.
!Always maintain a distance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information about the
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
Rbattery
Rconnectors
Rlights
Rseals
Rtrim
Rventilation slots
Damaged seals or electrical components can
lead to leaks or failures.
Cleaning the wheels
!Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
!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

Maintenance and care

Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate if the
system is not operating properly. The TPMS
malfunction indicator is combined with the
low tire pressure telltale. When the system
detects a malfunction, the warning lamp will
flash for approximately a minute and then
remain continuously illuminated. This
sequence will be repeated every time the vehi-
cle is started as long as the malfunction
exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons,
including the mounting of incompatible
replacement or alternate tires or wheels on
the vehicle that prevent the TPMS from func-
tioning properly. Always check the TPMS mal-
function telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels
allow the TPMS to continue to function prop-
erly.
It is the driver's responsibility to set the tire
pressure to the recommended cold tire pressure
suitable for the operating situation
(
Ypage 265). Note that the correct tire pressure
for the current operating situation must first be
taught-in to the tire pressure monitor. If there is
a substantial loss of pressure, the warning
threshold for the warning message is aligned to
the reference values taught-in. Restart the tire
pressure monitor after adjusting to the cold tire
pressure (
Ypage 270). The current pressures
are saved as new reference values. As a result, a
warning message will appear if the tire pressure
drops sign ificant
ly.
The tire pressure monitor does not warn you of
an incorrectly set tire pressure. Observe the
notes on the recommended tire pressure
(
Ypage 265).
The tire pressure monitor is not able to warn you
of a sudden loss of pressure, e.g. if the tire is
penetrated by a foreign object. In the event of a
sudden loss of pressure, bring the vehicle to a
halt by braking carefully. Avoid sudden steering
movements.
In order to check the tire pressure, the vehicle's
wheels are installed with sensors that monitor the tire pressure in all four tires. The tire pres-
sure monitor warns you if the pressure drops in
one or more of the tires. The tire pressure mon-
itor only functions if the correct sensors are
installed on all wheels.
The tire pressure monitor has a yellow warning
lamp in the instrument cluster for indicating
pressure loss/malfunctions (USA) or pressure
loss (Canada). Whether the warning lamp
flashes or lights up indicates whether a tire
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.
RUSA only: if the warning lamp flashes for
around a minute and then remains lit con-
stantly, the tire pressure monitor is malfunc-
tioning.
Information on tire pressures is displayed in the
multifunction display. After a few minutes of
driving, the current tire pressure of each tire is
shown in the multifunction display.
USA only: the tire pressure warning lamp will
inform you of a malfunc
tion in the tire pressure
monitor by flashing for approximately one
minute and then remaining lit. It may take more
than ten minutes before the data menu is dis-
played. When the malfunction has been recti-
fied, the tire pressure warning lamp goes out
after a few minutes of driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at a gas station with a pressure gauge. 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 gauge 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 interference from radio transmit-
ting equipment (e.g. radio headphones, two-way
radios) that may be being operated in or near the
vehicle.

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 a few minutesmessage appears.
After a teach-in process, the tire pressure mon-
itor automatically detects new wheels or new
sensors. As long as a clear allocation of the tire
pressure value to the individual wheels is not
possible, theTire
PressureMonitorActivedisplay message is shown instead of the tire
pressure display. The tire pressures are already
being monitored.
iIf a spare wheel is mounted, the system may
continue to show the tire pressure of the
wheel that has been removed for a few
minutes. Observe that the displayed value is
not the same as the current tire pressure of
the emergency spare wheel.
Tire pressure monitor warning mes-
sages
If the tire pressure monitor detects a significant
pressure loss on one or more tires, a warning
message is shown in the multifunction display. A
warning tone also sounds and the tire pressure
warning lamp lights up in the instrument cluster.
Each tire that is affected by a significant loss of
pressure is highlighted in the pressure display.
XIf the Correct Tire Pressuremessage
appears in the multifunction display, check
the tire pressure on all four wheels and cor-
rect it if necessary.
XIf the Check Tiresmessage appears in the
multifunction display, the tire pressure in one
or more tires has dropped significantly and
the tires must be checked.
XIf the Tire Press. Warning CautionTire Malfunctionmessage appears in the
multifunction display, the tire pressure in one
or more tires has dropped suddenly and the
tires must be checked.
iIf the wheel positions on the vehicle are
rotated, the tire pressures may be displayed
for the wrong positions for a short time. This is
rectified after a few minutes of driving, and
the tire pressures are displayed for the cor-
rect positions.
Restarting the tire pressure monitor
When you restart the tire pressure monitor, all
existing warning messages are deleted and the
warning lamps go out. The monitor uses the cur-
rently set tire pressures as the reference values for monitoring. In most cases, the tire pressure
monitor will automatically detect the new refer-
ence values after you have changed the tire
pressure. However, you can also define refer-
ence values manually as described here.
XSet the tire pressure to the value recommen- ded for the corresponding driving situation on
the Tire and Loading Information placard on
the driver's side B-pillar (
Ypage 265).
Additional tire pressure values for different
loads can also be found on the tire pressure
table on the inside of the fuel filler flap
(
Ypage 265).
XMake sure that the tire pressure is correct on
all four wheels.
