ary vehicle for up to 30 minutes after the
engine has been switched off. The heating
time depends on the set interior temperature.
i The blower will run at a low speed regard-
less of the airflow setting.

Risk of injury
Never leave children unsupervised in the
vehicle. They could operate the sliding/tilt-
ing sunroof and injure themselves. Always
take the key with you when leaving the
vehicle, even if you only leave it for a short
time. G
Risk of injury
Make sure that nobody can become trap-
ped when you are opening and closing the
sliding/tilting sunroof. If danger threatens,
release the switch and push it briefly in any
direction to stop the sliding/tilting sunroof. G
Risk of injury
The glass in the sliding/tilting sunroof
could break in an accident. If you are not
wearing a seat belt, there is a risk that you
could be thrown through the opening in the
event of the vehicle overturning. Therefore,
always wear a seat belt to reduce the risk
of injuries. !
Only open the sliding/tilting sunroof if it
is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding/tilting sunroof. The seals could oth-
erwise be damaged.
i Resonance noises can occur in addition
to the usual airflow noises when the slid-
ing/tilting sunroof is open. They are caused
by minor pressure fluctuations in the vehi-
cle interior.
Change the position of the sliding/tilting
sunroof or open a side window slightly to
reduce or eliminate these noises.
i It is also possible to open and close the
sliding/tilting sunroof from the outside
using the "Summer opening" ( Y page 100)
and "Convenience closing" ( Y page 100)
features respectively. Controls

The following message appears in the
multi-function display:
Tyre pressure monitor restarted
The tyre pressure monitor has stored the
pressure of the tyres as a new reference
value.
If you wish to cancel the restart:
X Press the ç button. Winter driving
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. at a Mercedes-Benz
Service Centre, at the onset of winter.
! Do not use a sharp object to remove snow
or ice from the trim on the B-pillar between
the side windows. Winter tyres
Use
winter tyres at temperatures below +7 °
C and on snow or ice-covered roads. Only
then can the effect of the ABS and ESP ®
driv-
ing systems be ensured in winter too.
Use winter tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
Risk of accident
You must replace winter tyres with a tread
depth
of less than 4 mm immediately. They
are no longer suitable for winter use, in par-
ticular because they do not provide suffi-
cient grip. This could cause you to lose
control of your vehicle and cause an acci-
dent. Always observe the maximum permitted
speed

specified for the winter tyres you have
fitted. If you fit winter tyres which have a
lower maximum permitted speed than that of
the vehicle, affix an appropriate warning sign
in the driver's field of vision. This can be
obtained at a qualified specialist workshop,
e.g. from a Mercedes-Benz Service Centre.
In such circumstances, you should also
restrict the maximum speed of the vehicle
using permanent Speedtronic 26
to the maxi-
mum permissible speed for winter tyres
(Y page 144).
Once you have fitted the winter tyres:
X Restart the tyre pressure moni-
tor* (Y page 202). G
Risk of accident
If you fit the spare wheel* when driving with
winter tyres, bear in mind that driving sta-
bility will be impaired owing to unstable
cornering

characteristics caused by the dif-
ferent tyres. You should therefore adapt
your driving style and drive carefully.
Have the spare wheel* replaced at the
nearest qualified specialist workshop
which has the necessary specialist knowl-
edge and tools to carry out the work

Automatic car wash G
Risk of accident
The vehicle is braked when HOLD is activa-
ted. Therefore, deactivate HOLD before the
vehicle is washed in an automatic car wash.
You can wash the vehicle in an automatic car
wash from the very start.
! Do not use a touch-free automatic car
wash that uses chemical agents to wash
the vehicle.
Preferably use one with high-pressure jets for
prewashing.
If the vehicle is very dirty, prewash 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.
! Make sure the side windows are com-
pletely closed, the ventilation/heater
blower is fully turned off and the wind-
screen wiper switch is set to 0. The rain
sensor may otherwise be activated, for
instance, leading to inadvertent wiper sweeps being triggered. This could cause
damage to the vehicle.
After using an automatic car wash, wipe off
wax from the windscreen and the wiper
blades. This will prevent smears and reduce
wiping

noises caused by residue on the wind-
screen.
High-pressure cleaners G
Risk of accident
Do not use high-pressure cleaners with cir-
cular-jet nozzles (dirt grinders) to clean
your vehicle or - especially - the tyres. You
could otherwise damage the tyres and
cause an accident.
! 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 Bulbs
R Seals
Damaged seals or electrical components
can lead to failures or leaks.
Cleaning the wiper blades and the out-
side of the windscreen G
Risk of injury
Turn the key to position 0 in the ignition
lock
before cleaning the windscreen or the
wiper blades. There is otherwise a risk of
the windscreen wipers being set in motion
and causing injury.
X Turn the key to position 1 in the ignition
lock (Y page 74).
X Set the windscreen wipers to the u
position on the combination switch
(Y page 97).
X Turn the key to position 0
or remove it when
the wiper arms are vertical ( Y page 74). Operation

!
Only fold the windscreen wipers away
from the windscreen when vertical, other-
wise you will damage the bonnet.
X Fold the wiper arms away from the wind-
screen until you feel them engage.
X Clean the windscreen and the wiper blades.
X Fold the windscreen wipers back again
before the ignition is switched on.
! Do not clean the wiper blades too often,
as otherwise the coating may come off.
This could cause wiper noise.
Cleaning the windows !
Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows.
Clean the insides of the windows with a
damp cloth or commercially-available glass
cleaner. Avoid touching the inside of the
rear windscreen and the side windows with
hard objects, e.g. ice scrapers or rings. You
could otherwise cause damage to the win-
dows, rear window heating or aerial on the
rear window. i
Anti-glare
film retrofitted to the insides of
the windows could interfere with radio or
mobile phone reception, especially if it is
conductive or metal-coated film. Informa-
tion about anti-glare film can be obtained
from any Mercedes-Benz Service Centre.
Cleaning the headlamps X
Clean the headlamp lenses with a wet
sponge.
! Only use washer fluid which is suitable
for plastic lenses. Unsuitable washer fluid
could damage the plastic lenses of the
headlamps.
Therefore, do not use the following:
R dry cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvent
You

could otherwise scratch or damage the
surface of the lenses. Plastic trim !
Do
not use dry, coarse or hard cloths and
do not scrub. Doing so will scratch or dam-
age the surfaces.
X Wipe plastic parts with a damp, lint-free
cloth (e.g. a microfibre cloth).
X Light soiling:
use a low-foaming soap (e.g.
a light liquid hand soap) diluted in water.
X Heavy soiling:
use a cleaning agent that is
solvent-free and non-corrosive. Mercedes-
Benz recommends that you use a
Mercedes-Benz cleaning product for this
purpose.
Cleaning the steering wheel boss and
dashboard X
Moisten a clean lint-free cloth with water.
X Clean the plastic parts and the dashboard.
X If particularly dirty, use a mild detergent. G
Risk of injury
Do not use cleaners and cockpit care
sprays containing solvents to clean the
cockpit and steering wheel boss. Cleaners
containing solvents cause the surface to
become porous and in the event of an air- Operation
