2009 MERCEDES-BENZ E-CLASS SALOON steering wheel

The tyre pressure loss warning system does
not replace the need to regularly check your
vehicle's tyre pressures, since an even loss of
pressure on several tyres at the same time
cannot be detected by the tyre pressure loss
warning system.
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.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's
tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt a very sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration).
R you are towing a very heavy or large trailer.
R you are driving with a heavy load (in the
vehicle or on the roof).
Restarting the tyre pressure loss warn-
ing system Restart the tyre pressure loss warning system
if you have:
R
changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, consult the table of tyre
pressures on the inside of the fuel filler flap
to ensure that the tyre pressure in all four
tyres is set correctly for the respective
operating conditions.
X Observe the notes in the section on tyre
pressures (Y page 225). G
Risk of accident
The tyre pressure loss warning system can
only give reliable warnings if you have set the
correct tyre pressure.
If an incorrect tyre pressure is set, these
incorrect values will be monitored.
A tyre with insufficient pressure results in
vehicle instability when driving, thus increas-
ing the risk of an accident.
X Make sure that the key is in position 2in
the ignition lock.
In the multi-function display you will see the
standard display (Y page 119).
X Press the =or; button to select the
Service menu.
X Press the 9or: button to select

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).

R snow chains must not be fitted to emer-
gency spare wheels, e.g. a "Minispare"
emergency spare wheel.
R Only fit snow chains in pairs and to the rear
wheels, even on vehicles with 4MATIC*.
Comply with the manufacturer's installa-
tion instructions.
On vehicles with AIRMATIC*, if snow chains
have been fitted, you may only drive at raised
vehicle level (Y page 154).
Do not exceed the maximum permissible
speed of 50 km/h.
i You may wish to deactivate ESP ®
when
pulling away with snow chains fitted
(Y page 60). This way, you can allow the
wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action). Winter driving
G
Risk of accident
Do not shift down for additional engine brak-
ing on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission: engage
neutral.
X Vehicles with automatic transmission*:
shift the selector lever to N.
X Try to bring the vehicle under control by
using corrective steering. Driving tips
Rolling with the engine switched off
G
Risk of accident
Never switch the engine off while the vehicle
is in motion.
There is no power assistance for the steering
and the service brake when the engine is not
running.
You will require considerably more effort to
steer and brake and you could therefore lose
control of the vehicle and cause an accident. Brakes
G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
Risk of accident
Make sure that other road users are not
endangered by your braking.
Downhill gradients On long and steep downhill stretches, espe-
cially if the vehicle is laden or towing a trailer,
you must shift to a lower gear in good time or,
on vehicles with automatic transmission*,
select shift range 1,2or 3.
i This also applies if you have activated
cruise control, Speedtronic or Distronic
Plus*.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously. Driving tips

Risk of injury
Do not use cleaning agents and cockpit care
spray containing solvents to clean the dash-
board and the steering wheel boss. If cleaning
agents containing solvents are used the sur-
faces become porous, then if an airbag is
deployed the disintegrating plastic parts may
cause serious injury.
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-
lowing: R
alcohol-based solvents or petrol
R abrasive cleaning agents
R commercially-available household clean-
ing agents
These may damage the display surface. Do
not exert pressure when cleaning the dis-
play surface as this may lead to irreversible
damage.
Cleaning the seat covers !
Do not use microfibre cloths to clean gen-
uine leather, artificial leather or
Alcantara ®
covers, as these are too aggres-
sive and, if used often, may damage the
cover.
! Clean:
R genuine leather covers with a damp
cloth, then wipe the covers down with a
dry cloth. Make sure that the leather
does not become soaked. For leather
care, use a leather care agent recom-
mended by Mercedes-Benz. You can
obtain information about this from any
Mercedes-Benz Service Centre.
R artificial leather covers with a cloth mois-
tened with a solution containing 1%
detergent (e.g. washing-up liquid).
R cloth covers with a microfibre cloth mois-
tened with a solution containing 1%
detergent (e.g. washing-up liquid). Rub
carefully and always wipe entire seat sec-
tions to avoid leaving visible lines. Leave
the seat to dry afterwards. Cleaning
results depend on the type of dirt and
how long it has been there.
R Alcantara ®
