Driving
tips 183
X
Vehicles with manual transmission: engage
neutral.
X Vehicles with AUTOTRONIC*: shift the
selector lever to N.
X Try to bring the vehicle under control using
corrective steering. Driving tips
Rolling with the engine switched off
G
Risk of accident
Never switch the engine off while the vehi-
cle is in motion.
There is no power assistance for the steer-
ing 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. Braking
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 AUTOTRONIC*, select shift
range
1,2or 3.
i This also applies if you have activated
cruise control* or Speedtronic*.
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.
Heavy and light loads If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the air-
flow to cool the brakes more quickly.
G
Risk of accident
Never depress the brake pedal continu-
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying
constant slight pedal pressure. This causes
the brake system to overheat, increases Operation

Driving ab
road 185Driving on wet roads
If water has accumulated to a certain depth
on the road surface, there is a danger of aqua-
planing occurring, even if:
R you drive at low speeds
R the tyres have adequate tread depth
For this reason, do not drive in tyre ruts, and
brake carefully. Driving on flooded roads
If you have to drive on stretches of road on
which water has collected, please bear in
mind that:
R the maximum permitted still water depth is
25 cm.
R you should drive no faster than at walking
pace.
! Bear in mind that vehicles travelling in
front or in the opposite direction create
waves. This may cause the maximum per-
missible water depth to be exceeded.
Failure to observe these notes may result
in damage to the engine, electrical systems
and transmission. Driving abroad
Points to remember
An extensive Mercedes-Benz Service network
is also available in other countries. The
Service Hotline's current telephone numbers
for use when you are abroad are to be found
in the "Service24h" chapter of the Service
Booklet.
Only low-octane fuel is available in certain
countries.
You can find further information about fuel
grades on (Y page 168). Symmetrical dipped beam
If your journey takes you to countries where
vehicles are driven on sides of the road oppo-
site to the country in which the vehicle is reg-
istered, your headlamps must be switched to
symmetrical dipped beam. Oncoming traffic
will be dazzled less.
X Have the headlamps switched over at a
qualified specialist workshop, e. g. a
Mercedes-Benz Service Centre. G
Risk of accident
Remember to set the headlamps back to
asymmetrical dipped beam when you return to driving on the same side of the
road as that of the country in which your
vehicle was registered. You may otherwise
dazzle the oncoming traffic and could cause
an accident. Operation

Environmental note
Dispose of empty packaging, cleaning
cloths and polishing wads in an environ-
mentally responsible manner.
! Do not affix to painted surfaces or plastic
surfaces:
R stickers
R films
R magnetic plates
R scented oil bottles or similar items
Otherwise, you could damage the paint fin-
ish or plastic.
! Clean the water drainage channels of the
windscreen and the rear window at regular
intervals. Under certain circumstances,
deposits such as leaves, petals and pollen
may prevent water from draining away
leading to corrosion damage. Vehicle care
! Do not park the vehicle for a long period
of time directly after cleaning, especially if
the wheels have just been cleaned with a
wheel cleaner. Wheel cleaners could cause
rapid corrosion of the brake discs and
brake pads/linings. After cleaning, park
the vehicle when it is at normal operating
temperature.
Automatic car wash You can wash the vehicle in an automatic car
wash from the beginning.
!
Do not use a touch-free automatic car
wash that uses chemical agents to wash
the vehicle.
Preferably use automatic car washes with
high-pressure jets for pre-washing.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
X Remove the radio/telephone aerial.
! If you do not remove the radio/telephone
aerial, the automatic car wash may damage
it or the vehicle.
! 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 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 sensor may be activated, triggering
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 cir-
cular-jet nozzles (dirt grinders) to clean
your vehicle, in particular the tyres. Other-
wise, you could damage the tyres and
cause an accident.

from the windscreen when vertical. Other-
wise, you will damage the bonnet.
X Fold the wiper arms away from the wind-
screen.
X Wipe the windscreen and wiper blades with
a damp, lint-free cloth (e.g. a microfibre
cloth) and cleaning agent.
X Fold the wiper arms back on to the wind-
screen before the ignition is switched on.
! Do not clean the wiper blades too often
as this will result in damage to the surface
coating, leading to 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 plastic lenses of the headlamps
with a damp sponge.
