Driving safety sys
tems 49R
do not deactivate ESP ®
under any cir-
cumstances.
R only depress the accelerator pedal as far
as necessary when pulling away.
R adapt your driving style to suit the pre-
vailing road and weather conditions.
The vehicle could otherwise go into a skid.
ESP ®
cannot reduce the risk of an accident
if you drive too fast. ESP ®
cannot override
the laws of physics.
! If:
R the vehicle is being towed with the front
or rear axle raised,
R the parking brake is being tested using a
dynamometer,
the ignition must be switched off (key in
position 0or 1in the ignition lock). Other-
wise, application of the brakes by ESP ®
could destroy the brake system on the front
or rear axle.
! A function or performance test should
only be carried out on a twin-axle dyna-
mometer. If you wish to operate the vehicle
on such a dynamometer, please consult a
Mercedes-Benz Service Centre in advance. You could otherwise damage the drive train
or the brake system.
i If differential locks are switched on, ABS,
BAS and ESP ®
switch themselves off auto-
matically.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
Activating/deactivating ESP ® ESP
®
is activated automatically when the
engine is running.
It may be best to deactivate ESP ®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel G
Risk of accident
Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilise the vehi-
cle if the vehicle starts to skid or a wheel
starts to spin. If you deactivate ESP
®
:
R ESP ®
no longer improves driving stability.
R the engine's torque is no longer limited and
the drive wheels can spin. Spinning of the
wheels results in a cutting action, which
provides better grip.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
R and are driving at above 60 km/h, ESP ®
still intervenes when one wheel reaches its
grip limit even though it is switched off.
i If ESP ®
is deactivated and one or more
wheels start to spin, the vwarning lamp
in the instrument cluster flashes. In such
situations ESP ®
will not stabilise the vehi-
cle. Safety

!
Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tyres are fitted. Do not
fit used tyres if you have no information
about their previous usage. G
Risk of accident
If wheels or tyres other than those which
have been tested are fitted:
R the brakes or chassis components could
be damaged.
R wheel and tyre clearances can no longer
be guaranteed.
This could cause an accident.
Modification work on the brake system and
wheels is not permitted, nor is the use of
spacer plates or brake dust shields. This inva-
lidates the General Operating Permit for the
vehicle. Notes on selecting, fitting and replacing
tyres R
only fit tyres and wheels of the same type
and make.
R only fit tyres of the correct size onto the
wheels.
R after fitting new tyres, run them in at mod-
erate speeds for the first 100 km as they
only reach their full performance after this
distance.
R fit new tyres on the front wheels first if tyres
of the same size are required on the front
and rear wheels.
R replace the tyres after six years at the lat-
est, regardless of wear. This also applies to
the spare wheel.
R do not drive with tyres which have too little
tread depth, as this significantly reduces
the traction on wet roads (aquaplaning).
! Store tyres that are not being used in a
cool, dry and preferably dark place. Protect
the tyres against oil, grease, petrol and die-
sel. Notes on regularly inspecting wheels
and tyres R
regularly check the wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bumps on tyres and deforma-
tion, cracks or severe corrosion on wheels),
at least every 14 days, as well as after driv-
ing off-road or on rough roads. Damaged
wheels could cause a loss of tyre pressure.
R regularly check the tyre tread depth and the
condition of the tread across the whole
width of the tyre (Y page 164). If neces-
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
R all wheels must have a valve cap to protect
the valve against dirt and moisture.
R regularly check the pressure of all your
tyres including the spare tyre, particularly
prior to long trips, and correct the pressure
as necessary (Y page 164).
Notes on driving R
while driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi-
cate that the wheels or tyres are damaged.
If you suspect that a tyre is defective, Operation

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 164).
X Make sure that the key is in position 2in
the ignition lock.
The standard display appears in the multi-
function display (Y page 101).
X Press the jork button to select the
Tyre pressure function on the multi-func-
tion steering wheel or wait until the follow-
ing message appears:
Tyre pressure displayed only after
driving a few mins.
X Press the reset button on the left of the
instrument cluster (Y page 96).

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 on the multi-func-
tion steering wheel.
The tyre pressure values stored at the last
restart will continue to be monitored. 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 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. Front tyres
typically wear more on the shoulders and the
rear tyres in the centre.
Interchange the wheels 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.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and
reactivate the tyre pressure monitor* if nec-
essary. Operation
* optional

Care
183H
Environmental note
Dispose of empty packaging, cleaning
cloths and polishing wads in an environ-
mentally responsible manner.
! Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces, otherwise you could
damage the paintwork. 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 without
brushes.
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.
! Make sure that the side windows are com-
pletely closed, that the ventilation/heater
blower is fully turned off and that the wind-
screen wiper switch is set to 0. The rain
sensor may otherwise be activated, trig-
gering unintended wiper movements. This
could cause damage to the vehicle.
After using an automatic car wash, wipe any
wax and drying agents off 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 or ― especially ― the tyres.
Otherwise, you could 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 lights
R seals
Damaged seals or electrical components
can lead to failures or leaks. Operation

warning lamps at a suitable distance.
Observe legal requirements. Changing a wheel and fitting the spare
wheel G
Risk of accident
If the spare wheel is more than six years
old, or it does not correspond to the regular
wheel type: have the spare wheel replaced
by a new wheel at the nearest qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
Never drive the vehicle with more than one
spare wheel fitted.
Vehicles with different tyre dimensions on
the front and rear axles: wheel and tyre size
of the spare wheel and normal wheel are
different. When using the spare wheel, the
handling characteristics are compromised.
Do not exceed the maximum speed of 80
km/h. G
Risk of accident
Vehicles with AMG equipment: when you fit
the spare wheel, make sure you observe the
following:
R the maximum speed of 80 km/h
R the prescribed tyre pressure
Preparing the vehicle X
Prepare the vehicle as described
(Y page 243).
X If a trailer is coupled, uncouple it.
X Remove the vehicle tool kit and the jack
(Y page 191).
X Remove the spare wheel from the spare
wheel bracket (Y page 192).
X Secure the vehicle to prevent it from rolling
away.
On level ground: place chocks or similar
items under the front and rear of the wheel
that is diagonally opposite the wheel you
wish to change.
X On downhill gradients: place chocks or
similar items under both wheels of the
other axle. Raising
the vehicle G
Risk of injury
The jack is designed only to raise the vehi-
cle for a short time while a wheel is being
changed.
The vehicle must be placed on stands if you
intend to work under it.
Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar items as jacking supports.
Otherwise, the jack will not be able to ach-
ieve its load-bearing capacity due to the
restricted 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. when starting the engine, opening
or closing a door or the tailgate) and you
could be seriously injured. G
Risk of accident
If you fail to position the jack correctly, the
vehicle may: Practical advice
