Wheels and tiresVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Tire inflation pressure Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:▷The service life of the tires.▷Road safety.▷Driving comfort.
Checking the pressure
Tires have a natural, consistent loss of pres‐
sure.
Check the tire inflation pressure regularly
Regularly check the tire inflation pres‐
sure, and correct it as needed: at least twice a
month and before a long trip. If you fail to ob‐
serve this precaution, you may be driving on
tires with incorrect tire pressures, a condition
that may not only compromise your vehicle's
driving stability, but also lead to tire damage
and the risk of an accident.◀
Tires heat up during driving, and the tire infla‐
tion pressure increases along with the temper‐
ature of the tire. The tire inflation pressure
specifications relate to cold tires or tires with
the ambient temperature.
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been parked for at least 2 hours.
After correcting the tire inflation pressure:▷Reinitialize the Flat Tire Monitor.▷Reinitialize the Tire Pressure Monitor.
Pressure specifications The tire inflation pressure table, refer to
page 167, contains all pressure specifications
for the specified tire sizes at the ambient tem‐
perature. Pressure specifications apply to ap‐
proved tire sizes and recommended tire
brands. This information can be obtained from
your service center.
To identify the correct tire inflation pressure,
please note the following:
▷Tire sizes of your vehicle.▷Maximum permitted driving speed.
Tire inflation pressures up to
100 mph/160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure
values in the tire inflation pressure table, refer
to page 167, and adjust as necessary.
These pressure values can also be found on
the tire inflation pressure label on the driver's
door pillar.

Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.
Run-flat tires
Label
RSC label on the tire sidewall.
The wheels are composed of special rims and
tires that are self-supporting, to a limited de‐
gree.
The support of the sidewall allows the tire to
remain drivable to a restricted degree in the
event of a pressure loss.
Continued driving with a damaged tire, refer to
page 103.
Continued driving with a damaged tire, refer to
page 100.
Changing run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire.
Your service center will be glad to advise you.
Snow chains
Fine-link snow chains
Only certain types of fine-link snow chains
have been tested by the manufacturer of the
vehicle, classified as road-safe and approved.
Information about the approved snow chains
are available from the service center.
Use
Use only in pairs on the rear wheels, equipped
with the tires of the following size:▷205/55 R 16.▷205/50 R 17.▷225/45 R 17.
Follow the chain manufacturer's instructions.
Make sure that the snow chains are always
sufficiently tight. Retighten as needed accord‐
ing to the chain manufacturer's instructions.
Do not initialize the Flat Tire Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
Do not initialize the Tire Pressure Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
When driving with snow chains, briefly activate
Dynamic Traction Control if necessary.
Maximum speed with snow chains Do not exceed a speed of 30 mph/50 km/h
when using snow chains.

bumper area. In addition to the two outer
fasteners, there is another inner fastener.4.Grasp the handle with one hand, arrow 1,
and brace with the free hand on the out‐
side, arrow 2. Carefully pry out the tail
lamp, arrow 3, until the rubber mount re‐
leases from the inner fastener.5.Remove the plug from the bulb holder.
Replacing the bulbs
1.Loosen the six fasteners on the tail lamp
and remove the tail lamp from the lamp
holder.2.Press the defective bulb gently into the
socket, turn counterclockwise and remove.3.Proceed in the reverse order to insert the
new bulb and attach the bulb holder to the
tail lamp. Make sure that the bulb holder
engages in all fasteners.
Installing the tail lamp
1.Connect the plug to the bulb holder.2.Insert the tail lamp straight in and press it
in, arrow 1, until the rubber mount latches
in the inner fastener. Make sure when in‐
serting the tail lamp that the rubber lip, ar‐
row 2, on the top side of the tail lamp does
not fold over. Screw on the two nuts, ar‐
row 3, and close covers.
Central brake lamp and license plate
lamp
Follow the general instructions on lamps and
bulbs, refer to page 183.
These lamps are made using LED technology.
Contact your service center in the event of a
malfunction.
Changing wheels
Hints
The vehicle equipment does not include a
spare tire.
When using run-flat tires or tire sealants, a tire
does not need to be changed immediately in
the event of pressure loss due to a flat tire.
The tools for changing wheels are available as
accessories from your service center.

CareVehicle equipmentAll standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Car washes Hints Steam jets or high-pressure washers
When using steam jets or high-pressure
washers, hold them a sufficient distance away and use a maximum temperature of
140 ℉/60 ℃.
If the vehicle has a glass sunroof, ensure that a distance of at least 31.5 inches/80 cm is main‐
tained. Holding them too close or using exces‐
sively high pressures or temperatures can
cause damage or preliminary damage that may
then lead to long-term damage.
Follow the user's manual for the high-pressure
washer.◀
Cleaning sensors/cameras with high-
pressure washers
When using high-pressure washers, do not
spray the exterior sensors and cameras, e.g., Park Distance Control, for extended periods of
time and only from a distance of at least
12 in/30 cm.◀▷Regularly remove foreign items such as
leaves in the area below the windshield
when the hood is raised.▷Wash your vehicle frequently, particularly
in winter.Intense soiling and road salt can damage
the vehicle.
Automatic car washes
Hints
▷Give preference to cloth car washes or
those that use soft brushes in order to
avoid paint damage.▷Make sure that the wheels and tires are not
damaged by the transport mechanisms.▷Fold in the exterior mirrors; otherwise, they
may be damaged, depending on the width
of the vehicle.▷Deactivate the rain sensor, refer to
page 69, to avoid unintentional wiper acti‐
vation.▷In some cases, an unintentional alarm can
be triggered by the interior motion sensor
of the alarm system. Follow the instruc‐
tions on avoiding an unintentional alarm,
refer to page 44.
Guide rails in car washes
Avoid car washes with guide rails higher
than 4 in/10 cm; otherwise, the vehicle body
could be damaged.◀
Before driving into a car wash In order to ensure that the vehicle can roll in a
car wash, take the following steps:
Manual transmission:
1.Drive into the car wash.2.Shift to neutral.3.Switch the engine off.4.Switch on the ignition.
Automatic transmission:
1.Drive into the car wash.Seite 199CareMobility199
