Incorrect wheel and tire combinations impair
the function of a variety of systems such as
ABS or DSC.
To maintain good handling and vehicle re‐
sponse, use only tires with a single tread con‐
figuration from a single manufacturer.
Following tire damage, have the original wheel
and tire combination remounted on the vehicle
as soon as possible.
WARNING
Wheels and tires which are not suitable
for your vehicle can damage parts of the vehi‐
cle, e. g. due to contact with the body due to
tolerances despite the same official size rating.
There is risk of an accident.◀
Recommended tire brands
For each tire size, the manufacturer of your ve‐
hicle recommends certain tire brands. These
can be identified by a star on the tire sidewall.
New tires
Tire traction is not optimal due to manufactur‐
ing circumstances when tires are brand-new;
they achieve their full traction potential after a
break-in time.
Drive conservatively for the first
200 miles/300 km.
Retreaded tires
The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
WARNING
Retreated tires can have different tire
casing structures. With advanced age the serv‐
ice life can be limited. There is risk of an acci‐
dent. Do not use retreated tires.◀
Winter tires
Winter tires are recommended for operating on
winter roads.
Although so-called all-season M+S tires pro‐
vide better winter traction than summer tires,
they do not provide the same level of perform‐
ance as winter tires.
Maximum speed of winter tires If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then a respective symbol is displayed in your
field of vision. The plate is available from a
dealer’s service center or another qualified
service center or repair shop.
With mounted winter tires, observe and adhere
to the permissible maximum speed.
Run-flat tires If you are already using run-flat tires, for your
own safety you should replace them only with
the same kind. No spare tire is available in the
case of a flat tire. A dealer’s service center or
another qualified service center or repair shop
will be glad to answer additional questions at
any time.
Rotating wheels between axles Different wear patterns can occur on the front
and rear axles depending on individual driving
conditions. The tires can be rotated between
the axles to achieve even wear. A dealer’s
service center or another qualified service cen‐
ter or repair shop will be glad to answer addi‐
tional questions at any time. After rotating,
check the tire pressure and correct if needed.Seite 191Wheels and tiresMobility191

Information CAUTION
Improper use of the socket for Onboard
Diagnosis can lead to vehicle malfunctions.
There is risk of property damage. The manu‐
facturer of your vehicle strongly recommends
access to the socket for Onboard Diagnosis be
limited to a dealer's service center, another
qualified service center or repair shop or other

checking the primary components in the vehi‐
cle's emissions.
Emissions
▷The warning lamp lights up:
Emissions are deteriorating. Have
the vehicle checked as soon as
possible.▷The warning lamp flashes under certain
circumstances:
This indicates that there is excessive mis‐
firing in the engine.

service center or another qualified service cen‐
ter or repair shop.
WARNING
Bulbs can get hot during operation. Con‐
tact with the bulbs can cause burns. There is
risk of injuries. Only change bulbs after they
have cooled off.◀
WARNING
Work on switched-on lighting systems
can cause short circuits. There is risk of inju‐
ries or risk of property damage. When working
on the lighting system, switch off the lamps in
question. If necessary, heed the bulb manufac‐
turer's instructions.◀
CAUTION
Contaminated bulbs reduce their service
life. There is risk of property damage. Do not
hold new bulbs with your bare hands. Use a
clean cloth or something similar, or hold the
bulb by its base.◀
Light-emitting diodes (LEDs)
Some items of equipment use light-emitting
diodes installed behind a cover as a light
source.
These light-emitting diodes, which are related
to conventional lasers, are officially designated
as Class 1 light-emitting diodes.
WARNING
Too intensive brightness can irritate or
damage the retina of the eye. There is risk of
injuries. Do not look directly into the headlights
or other light sources for an extended period of
time. Do not remove the LED covers.◀
Headlight glass
Condensation can form on the inside of the ex‐
ternal lights in cool or humid weather. When
driving with the lights switched on, the con‐
densation evaporates after a short time. The
headlight glass does not need to be changed.If despite driving with the lights switched on,
increasing humidity forms, e. g. water droplets
in the lamp, the manufacturer of your vehicle
recommends having it checked by a dealer’s
service center or another qualified service cen‐
ter or repair shop.
Headlight setting
The headlight adjustments can be affected by
changing lights and bulbs. After the headlight
adjustment was changed, have it checked and,
if necessary, corrected by a dealer’s service
center or another qualified service center or re‐
pair shop.

Safety measures
▷Park the vehicle as far away as possible
from passing traffic and on solid ground.
Switch on the hazard warning system.▷Set the parking brake and engage lever in
position P P.▷Have all vehicle occupants get out of the
vehicle and ensure that they remain out‐
side the immediate area in a safe place,
such as behind a guardrail.▷If necessary, set up a warning triangle or
portable hazard warning lamp at an appro‐
priate distance.▷Perform wheel change only on a flat, solid
and slip-resistant surface. On soft or slip‐
pery ground, e.g., snow, ice, tiles, etc., the
vehicle or vehicle jack can slip away to the
side.▷Do not place wood blocks or similar items
under the vehicle jack; otherwise, it cannot
reach its carrying capacity because of the
restricted height.▷If the vehicle is raised, do not lie under the
vehicle and do not start the engine; other‐
wise, a fatal hazard exists.Seite 213Replacing componentsMobility213
