Driving safety systems
59ESP
®
(Electronic Stability Program)
ESP ®
monitors driving stability and traction,
i.e. power transmission between the tyres
and the road surface.
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle.
The engine output is also modified, if
necessary, to keep the vehicle on the desired
course within the scope of the laws of phys-
ics. ESP ®
assists the driver when pulling away
on wet or slippery roads. ESP ®
can also sta-
bilise the vehicle during braking.
When ESP ®
intervenes, the v warning
lamp flashes in the instrument cluster. G
Risk of accident
If the v
warning lamp in the instrument
cluster flashes, proceed as follows:
R
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 the vehicle is to be towed with the front
or rear axle raised, the ignition must be
switched off (key in position 0 or 1 in the
ignition lock). Application of the brakes by
ESP ®
could otherwise destroy the brake
system on the front or rear axle.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
To deactivate/activate 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 Engine torque is not limited and the drive
wheels are able to spin. The spinning
wheels produce a cutting effect for better
traction.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
i If ESP ®
is deactivated and one or more
wheels start to spin, the v warning lamp
in the instrument cluster flashes. ESP ®
does not, stabilise the vehicle. Safety

Tyres and wheels
198 Tyres and wheels
Points to remember
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle. These tyres have been specially adap-
ted for use with the control systems, such
as
ABS or ESP ®
, and are marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(with run-flat characteristics)*
Mercedes-Benz Original Extended tyres*
should only be used on wheels that have
been specifically approved by Mercedes-
Benz.
If you use other tyres and wheels,
Mercedes-Benz cannot accept any respon-
sibility for damage that may result from
this. Further information about tyres,
wheels and approved combinations can be
obtained from any Mercedes-Benz Service
Centre.
If you use tyres other than those tested and
recommended for Mercedes-Benz vehi-
cles, characteristics such as handling, vehi-
cle noise emissions and fuel consumption may be adversely affected. In addition, the
wheels may come into contact with the
body

or axle components when heavily loa-
ded or when driving with snow chains. This
could result in damage to the tyres or the
vehicle.
! 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. Operation

Risk of accident
If the tyre pressure is now lower than
1.3 bar, the tyre is too badly damaged. 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 rec-
ommends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, work relevant to safety or on safety-
related systems must be carried out at a
qualified specialist workshop.9 Pressure release button

G Risk of accident
Do not exceed the maximum speed of 80
km/h.
The “max. 80 km/h” sticker must be affixed
within the driver's field of vision.
The vehicle's handling characteristics may
be affected.
H Environmental note
Have the used TIREFIT kit disposed of pro-
fessionally, e.g. at a Mercedes-Benz
Service Centre.
X Have the TIREFIT kit replaced every four
years at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
Changing a wheel and fitting the spare
wheel*
G Risk of accident
The wheel dimensions and tyre size of the
spare wheel*, the emergency spare
wheel* and standard wheels may differ
from one another.
Your vehicle's handling characteristics will
be altered when a "Minispare"/collapsible
emergency spare wheel* is fitted. Adapt
your style of driving accordingly.
The “Minispare”/collapsible emergency
spare wheel* must only be used as a tem-
porary measure. Do not exceed the maxi-
mum speed of 80 km/h and do not
deactivate ESP ®
.
Never drive the vehicle with more than one
“Minispare”/collapsible emergency spare
wheel* fitted.
G Risk of accident
Have the “Minispare”/collapsible emer-
gency spare wheel* or the spare wheel*
replaced with a new wheel as soon as pos-
sible at a qualified specialist workshop
which has the necessary specialist knowl-
edge and tools to carry out the work

X Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indica-
ted ( 1 to 5). The tightening torque must
be 130 Nm. G
Risk of accident
Have the tightening torque checked imme-
diately after a wheel is changed. The wheels
could work loose if they are not tightened
to a tightening torque of 130 Nm.
X Turn the jack back to its initial position and
store it and the rest of the vehicle tool kit
in the boot.
Vehicles with the "Minispare"/collapsible
emergency spare wheel*:
