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
WARNING
Activate ESP ®
as soon as the situations
describe dabove no longer apply. ESP ®
will
otherwis enot be abletos tabilise the vehicle
if the vehicle starts to skid or awhee lstarts
to spin.
When 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. The spinning of
the wheels results in acutting action, which
provide sbetter grip.
R traction control is still activated.
R ESP ®
still provide ssupport when you
brake.
If ESP ®
is deactivated and one or more wheels
start to spin, the ÷ESP®
warning lamp in
the instrument cluster flashes. In such situa-
tions, ESP ®
willn ot stabilise the vehicle.
X To deactivate: (Ypage 223).
The å ESP®
OFF warning lamp in the
instrument cluster lights up. G
WARNING
ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ouslyw hen the engine is running.
If the ÷ warning lamp and åwarning
lamp are lit continuously, ESP ®
is not availa-
ble due to amalfunction.
There is an increased risk of yourv ehicle skid-
ding in certain situations.
You should alway sadapt your driving style to
suit the prevailing road and weather condi-
tions. X
To activate:(Y page 223).
The å ESP®
OFF warning lamp in the
instrument cluster goes out.
ESP ®
trailer stabilisation If your vehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilise the vehicle/trailer combination by
depressing the brake firmly.
In this situation ,ESP ®
assists you and can
detec tifthe vehicle/trailer combination
begins to lurch. ESP ®
slows the vehicle down
by braking and limiting the engine output until
the vehicle/trailer combination has stabi-
lised.
Trailer stabilisation is active above speeds of
about 65 km/h. G
WARNING
If road and weather conditions are poor,
trailer stabilisation will not be able to prevent
the trailer from swerving and will thus be
unable to reduce the risk of an accident. Trail-
ers with ahigh centre of gravity can tip over
before ESP ®
can detect this.
Trailer stabilisation does not work if ESP ®
is
deactivated or disabled because of amal-
function. EBD (electronic brake force distribu-
tion)
i Observe the "Important safety notes" sec-
tion (Y page 61).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. G
WARNING
If EBD has malfunctioned, the braking system
remains available with full brake boosting
effect.H owever, the rear wheels can still lock,
e.g. under full braking. This could cause you
to lose control of your vehicle and cause an
accident .You should therefor eadapt your Driving safety systems

not drive the vehicle any further. Consult a
qualified specialist workshop which has the
necessary specialist knowledge and tools to
carry out the work required. Mercedes-Benz
recommends that you use aMercedes-Benz
Service Centr eorService 24h for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop. G
WARNING
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been
approved for Mercedes-Benz vehicles and the
respective wheel. Other wheel bolts could
work loose or damage the brake system.
Do not tighten the wheel bolts completely
while the vehicle is still jacked up. The vehicle
could topple off the jack.

the work required
.Mercedes-Benz recom-
mend stha tyou use aMercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at aqualified spe-
cialist workshop.
The wheels could work loose if they are not
tightened to atorque of 130 Nm.
For safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts of the
correc tsize which have been approved for
Mercedes-Ben zvehicles.
The wear patterns on the fron tand rea rtyres
differ ,dependin gontheoperatin gconditi ons.
Interchange th ewheels befor eaclear wear

rea rtyre sint he centre.
On vehicle sthat have the same size front and
rea rwheels, you can interchange the wheels
every 5000 km to 10,000 km depending on
the degree of tyre wear. Do not reverse the
direction of tyre rotation.
Cleant he contact surfaces of the wheel and
the brake disc thoroughly every time awheel
is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss
warning system or the tyre pressure monitor.
! On vehicles fitted with atyre pressure
monitor, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Always have the tyres changed at aquali-
fied specialist workshop, e.g. aMercedes-
Benz Service Centre. Direction of rotation
Tyres with aspecified direction of rotation
have additional benefits, e.g. if there is arisk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed. An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
You may fit an emergency spare wheel/spare
wheel against the direction of rotation.
Observe the time restriction on use as well as
the speed limitation specified on the emer-
gency spare wheel/spare wheel.
Storing wheels
Storew heels that are not being used in acool,
dry and preferably dark place. Protect the
tyres against oil, grease, petrol and diesel. Cleaningt

WARNING
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent. Wheel and tyrec
