X Press the abutton.
The tyre pressure values stored at the last
restart will continue to be monitored. Tyre pressure monitor*
If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that
monitor the tyre pressures in all four tyres.
The tyre pressure monitor warns you when
the pressure drops in one or more of the
tyres. The tyre pressure monitor only func-
tions if the correct wheel electronics units are
fitted to all wheels. G
Risk of accident
The tyre pressure monitor does not warn you
of an incorrectly set tyre pressure. The table
on the inside of the fuel filler flap will help you
decide whether the tyre pressures should be
corrected.
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tyre is penetrated by a foreign body. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Do not
make any sudden steering movements when
doing so.
i The operation of the tyre pressure moni-
tor can be affected by interference from
radio transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.
Checking tyre pressure electronically X
Make sure that the key is in posi-
tion 2(Y page 182) in the ignition lock.
X Press the =or; button to select the
Service menu.
X Press the 9or: button to select
Tyre pressure.
X Press the abutton. The current tyre pressure for each wheel will
be displayed.
If the vehicle has been parked for longer than
20 minutes or if you have not driven faster
than 25 km/h since starting the vehicle, the

i
The tyre pressure values indicated by the
on-board computer may differ from those
measured at a filling station with a pressure
gauge. The tyre pressures shown by the on-
board computer refer to those measured at
sea level. The tyre pressure values indica-
ted by a pressure gauge when the vehicle
is at high altitude are higher than those
shown by the on-board computer. In this
case, do not reduce the tyre pressures.
i After a teach-in period, the tyre pressure
monitor automatically recognises new
wheels or new sensors. As long as a clear
allocation of the tyre pressure values to the
individual wheels is not possible, the dis-
play message Tyre Pressure Monitor
Active is shown instead of the tyre pres-
sure display. The tyre pressures are already
being monitored.
Restarting the tyre pressure monitor When you restart the tyre pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tyre pressures as the speci-
fied values for monitoring.
In most cases, the tyre pressure monitor will
automatically detect the new reference val-
ues, e.g. if you have:
R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
i You will find the menu overview on
(Y page 214).
If you wish to define the new reference values
manually:
X Use the table on the inside of the fuel filler
flap to ensure that the tyre pressure is set
correctly in all four tyres for the current
operating conditions. Also observe the notes in the section on
tyre pressures (Y
page 298).
X Make sure that the key is in position 2in
the ignition lock.
X Press the =or; button to select the
Service menu.
X Press the 9or: button to select
Tyre pressure.
X Press the abutton.
The current pressure in each individual tyre
is displayed, or the following message
appears:

driving a few minutes
X Press the :button.
The following message appears in the
multi-function display:

X Press the abutton.
The following message appears in the
multi-function display:

After a few minutes of driving, the current
pressures are adopted as the new monitor-
ing values.
Cancelling the restart X
Press the %button.
or
X Press the 9button to leave the menu.

display If in multi-function display the following mes-
sages appear:

R
Vehicles with a key:
Do not remove the key from the ignition
lock. Do not open the driver's or front-
passenger door when the engine is
switched off, as this automatically shifts
the automatic transmission to park posi-
tion Pand locks the wheels, unless you
have previously shifted the automatic
transmission to N.
R Vehicles with KEYLESS GO*:
Do not open the driver's or front-
passenger door when the engine is
switched off, as this shifts the automatic
transmission to park position Pand locks
the wheels.
! Make sure that the side windows are com-
pletely closed, that the ventilation/heater
blower is turned off and that the wind-
screen wiper switch is set to 0. Otherwise,
the rain/light sensor may be activated, trig-
gering unintended wiper movements. This
could cause damage to the vehicle.
After using an automatic car wash, wipe off
wax and drying agents from the windscreen
and the wiper blades. This will prevent smears
and reduce wiping noises caused by residue
on the windscreen.
High-pressure cleaners G
Risk of accident
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent.
! Observe the instructions issued by the
equipment manufacturer concerning the
distance to be maintained between the
nozzle of the high-pressure cleaner and the
vehicle (at least 30 cm).
Move the high-pressure cleaner nozzle
around when cleaning your vehicle. Do not aim directly at any of the following:
R
tyres
R door joint
R electrical components
R battery
R connectors
R lights
R seals
R trim elements
Damaged seals or electrical components
can lead to failures or leaks.
Matt finish care* Your vehicle has a clear matt finish. For this
reason, you should make sure that you
adhere to the following instructions to avoid
damage to paintwork due to improper treat-
ment.
! Under no circumstances should you pol-
ish the vehicle. Polishing will make the
paintwork shine.
! When caring for your paintwork, do not
use paint cleaner, grinding or polishing
products, or gloss preservers such as wax.
These products are only suitable for high-
gloss finishes. Using them on a vehicle with
a matt finish results in serious damage to
the surface (gleaming, spotted areas).
Always have paintwork repairs carried out
at a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
i From the range of available Mercedes-
Benz care products, use only the insect
remover and the car shampoo.
Cleaning the paintwork Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-308

Cleaning the sensors*
X
Clean sensors :for the driving systems
with water, car shampoo and a soft cloth.
! If you clean the sensors using a high-pres-
sure cleaner or steam cleaner, observe the
manufacturer's information on maintaining
the correct distance between the vehicle
and the high-pressure cleaner.
Cleaning the reversing camera* X
Use clear water and a soft cloth to clean
camera lens :.
! Do not clean the camera lens and the area
around the reversing camera with a high-
pressure cleaner. Cleaning the exhaust tail pipes Impurities combined with the effects of road
grit and corrosive environmental factors may
cause flash rust to form on the surface. Reg-
ular care of the exhaust tail pipes will ensure
that their original shine is restored.
!
Do not clean the exhaust tail pipes with
alkaline-based cleaning agents such as
wheel cleaner.
X Clean the exhaust tail pipes with a chrome
care product approved by Mercedes-Benz. Interior care
Cleaning the steering wheel boss and
dashboard G
Risk of injury
Do not use cleaners and cockpit care sprays
containing solvents to clean the cockpit and
steering wheel boss. Cleaners containing sol-
vents cause the surface to become porous
and in the event of an airbag being triggered,
plastic parts that have become loose could
cause considerable injuries.
X Wipe the dashboard and steering wheel
boss with a damp, lint-free cloth (e.g. a
microfibre cloth) and cleaning agent.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
Cleaning the COMAND display X
Before cleaning the display, make sure that
it is switched off and has cooled down.
X Clean the display surface using a commer-
cially-available microfibre cloth and TFT/
LCD display cleaner.
X Dry the display surface using a dry micro-
fibre cloth.
! For cleaning, do not use any of the fol-
