2009 MERCEDES-BENZ E-CLASS SALOON sensor

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 object. 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 75) in the ignition lock.
X Press the =or; button to select the
Service menu.
X Press the 9or: button to select
Tyre press.
X Press the abutton.
The current tyre pressure for each wheel will
be displayed in the multi-function display. 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
following message appears:
Tyre pressures will be displayed
after a few minutes of driving
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. At high altitudes, the tyre pres-
sure values indicated by a pressure gauge
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 120).

If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! 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. There is otherwise a risk of dam-
age to the exterior mirrors.
! When washing your vehicle in a tow-
through car wash, make sure that the auto-
matic transmission* is in position N. The
vehicle could otherwise be damaged.
R Vehicles with DIRECT SELECT lever and
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 DIRECT SELECT lever and
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
closed completely, that the blower for the
ventilation/heating is switched off and that
the windscreen wiper switch is in position
0. The rain/light sensor could otherwise be
activated and thereby cause unintentional
wiping. This could result in 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
R ventilation slots
Damaged seals or electrical components
can lead to failures or leaks.
Care and treatment of matt paint-
work* 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 Care

!
Only use washer fluid or cleaning cloths
suitable for plastic lenses. Unsuitable
washer fluid or cleaning cloths could
scratch or damage the plastic lenses of the
headlamps.
Cleaning the sensors* Saloon (example)
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* Saloon (example) 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.
Trailer coupling* The ball coupling must be cleaned if it
becomes dirty or corroded.
X
Remove any rust using a wire brush.
X Remove dirt with a clean, lint-free cloth or
a brush.
! Do not clean the ball coupling with a high-
pressure cleaner. Do not use solvents. Saloon (example)
X
After cleaning, lightly oil or grease ball cou-
pling :.
X Check that the vehicle's trailer coupling is
working properly. Care
