Tyres and wheels
233
Restarting the tyre pressure monitor 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
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 229).
X Make sure that the key is in position 2in
the ignition lock.
The standard display appears in the multi-
function display (Y page 125).
X Press the jork button to select the
Tyre pressure function or wait until the
following message appears:
Tyre pressure displayed only after
driving for a few minutes X
Press the reset button on the left of the
instrument cluster (Y page 243).
The following message appears in the
multi-function display: Check current
tyre pressure?
X Press the æbutton.
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 çbutton. Interchanging the wheels
G
Risk of accident
Interchange the front and rear wheels only
if they have the same dimensions: for exam-
ple size, offset, etc.
After every wheel interchange/change,
have the tightening torque checked at a
qualified specialist workshop that has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes- Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
The wheels could work loose if they are not
tightened to a torque of 130 Nm.
For safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts of the
correct size which have been approved for
Mercedes-Benz vehicles.
The wheels may be interchanged every
5,000 km to 10,000 km depending on the
degree of tyre wear, provided that the vehicle
has the same size front and rear tyres. Do not
reverse the direction of tyre rotation.
The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear wear
pattern has formed on the tyres. The front
tyres typically wear more on the shoulders
and the rear tyres in the centre.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss
warning system or the tyre pressure moni-
tor*. Operation

Driving
tips 236 Driving tips
Rolling with the engine switched off
G
Risk of accident
Do not switch off the engine while the vehi-
cle is in motion.
There is no power assistance for the steer-
ing or the service brake when the engine is
not running.
Steering and braking require significantly
more effort and you could lose control of
the vehicle and cause an accident as a
result. 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 automatic transmission*,
select shift range
1,2or 3.
i This also applies if you have activated
cruise control, Speedtronic or Distronic*.
This uses the braking effect of the engine and
you will not have to brake to such an extent
to maintain the same speed. This relieves the
load on the brake system and prevents the
brakes from overheating 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
the braking distance and can lead to the
brakes failing completely.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet roads If driving in heavy rain for a prolonged period
of time without braking, there may be a
delayed reaction from the brakes, when brak-
ing for the first time. You must brake harder.
You must therefore maintain a greater dis-
tance from the vehicle in front.
Brake firmly after driving on a wet road. This
way the brake discs will become warm, drying
more quickly, which will protect them against
corrosion. Operation

Where will I find...?
254 Vehicle tool kit, jack and spare
wheel*
The vehicle tool kit is located in a stowage
compartment underneath the floor of the
boot/luggage compartment. G
Risk of injury
The jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed.
If you are carrying out work on the vehicle,
you must use stands.
Make sure that the jack is placed on a firm,
non-slip and level surface. Do not use
wooden blocks or similar objects as a jack
underlay. Otherwise, the jack will not be
able to achieve its load-bearing capacity
due to the restricted height.
Do not start the engine at any time while a
wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise
the vehicle as described, it could slip off the
jack (e.g. if the engine is started or a door
or the boot lid/tailgate is opened or closed)
and you could be seriously injured. i
When using the jack, you should also
observe the safety notes in the "Flat tyre"
section (Y page 324).

Notes on changing bulbs
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that all bulbs function correctly at all times. G
Risk of injury
Bulbs and lamps can be very hot. You
should therefore allow them to cool down
before you change them. Otherwise, you
could be burned if you touch them.
Keep bulbs out of the reach of children.
Otherwise, they could damage them, for
example, and injure themselves.
Never use a bulb which has been dropped.
Such a bulb may explode and injure you.
H7 bulbs are pressurised and could explode
when you change them, particularly if they
are very hot. You should therefore wear eye
protection and gloves when you are chang-
ing them. G
Risk of injury
Xenon bulbs are under high voltage. You
could get an electric shock and be seriously
or even fatally injured if you touch the elec-
tric contacts on xenon bulbs. Do not, there-
fore, remove the cover on xenon bulbs. Practical advice

Flat tyre
318 Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar as jacking supports. Oth-
erwise, the jack will not be able to achieve
its load-bearing capacity due to the restric-
ted height.
Do not start the engine at any time while
the wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise
the vehicle as described, it could slip off the
jack (e.g. if the engine is started or a door
or the boot lid/tailgate is opened or closed)
and you could sustain serious injuries. Using the TIREFIT kit
You can use the TIREFIT kit to seal small
punctures, particularly those in the tyre tread.
You can use TIREFIT in outdoor temperatures
down to -20 °C. G
Risk of accident
In the following situations, your safety is at
particular risk and TIREFIT is unable to pro-
vide breakdown assistance: R
if there are cuts or punctures in the tyre
greater than 4 mm
R if the wheel rim is damaged
R if you have driven at very low tyre pres-
sures or on a flat tyre
Do not drive any further. Consult a qualified
specialist workshop which has the neces-
sary specialist knowledge and tools to carry
out the work required.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist work-
shop.
X Do not remove any foreign objects which
have penetrated the tyre, e.g. screws or
nails.
X Remove TIREFIT, the accompanying "max.
80 km/h "sticker and the electric air pump
from the stowage well underneath the
boot/luggage compartment floor
(Y page 254). 1

Brake fluid
Over a period of time, the brake fluid absorbs
moisture from the air; this lowers its boiling
point. G
Risk of accident
If the boiling point of the brake fluid is too
low, vapour pockets may form in the brake
system when the brakes are applied hard
(e.g. when driving downhill). This would
impair braking efficiency. Have the brake fluid renewed every two
years with a brake fluid that has been
approved by Mercedes-Benz and have this
confirmed in the Service Booklet.
i There is usually a notice in the engine
compartment to remind you when the next
brake fluid change is due. Windscreen washer system
The washer fluid reservoir holds approxi-
mately 4.5 litres; on vehicles with the head-
lamp cleaning system* it holds 7 litres.
The headlamp cleaning system* and the
windscreen washer system are both supplied
from the washer fluid reservoir.
X At temperatures above freezing point:
Top up the washer fluid reservoir with a
mixture of water and windscreen washer
concentrate (Y page 226).
X At temperatures below freezing point: Technical data
