This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features 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 tire inflation pressure
WARNING
A tire with low or missing tire inflation
pressure impacts handling, such as steering
and braking response. There is risk of an acci‐
dent. Regularly check the tire inflation pres‐
sure, and correct it as needed, e.g., twice a
month and before a long trip.◀
Tires have a natural, consistent loss of tire in‐
flation pressure.
Tires heat up while driving, and the tire infla‐
tion pressure increases along with the tire's
temperature. The tire inflation pressure speci‐
fications 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.
The displays of inflation devices may under-
read by up to 0.1 bar/2 psi.
For Flat Tire Monitor: after correcting the tire
inflation pressure, reinitialize the Flat Tire
Monitor.
For Tire Pressure Monitor: after correcting the
tire inflation pressure, reset the Tire Pressure
Monitor.
Tire inflation pressure specifications
The tire inflation pressure table, refer to
page 169, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. The tire inflation pres‐
sure values apply to tire sizes approved by the
manufacturer of the vehicle for the vehicle
type.
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 169, and adjust as necessary.

Tire treadSummer tires
Do not drive with a tire tread depth of less than
0.12 inches/3 mm.
There is an increased danger of hydroplaning if
the tire tread depth is less than 0.12 in‐
ches/3 mm.
Winter tires
Do not drive with a tire tread depth of less than
0.16 inches/4 mm.
Below a tread depth of 0.16 inches/4 mm, tires
are less suitable for winter operation.
Minimum tread depth
Wear indicators are distributed around the
tire's circumference and have the legally re‐
quired minimum height of 0.063 in‐
ches/1.6 mm.
They are marked on the side of the tire with
TWI, Tread Wear Indicator.
Tire damage
General information
Inspect your tires regularly for damage, foreign
objects lodged in the tread, and tread wear.
Information Driving over rough or damaged road surfaces,
as well as debris, curbs and other obstacles
can cause serious damage to wheels, tires and
suspension parts. This is more likely to occur
with low-profile tires, which provide less cush‐
ioning between the wheel and the road. Be
careful to avoid road hazards and reduce your
speed, especially if your vehicle is equipped
with low-profile tires.
Indications of tire damage or other vehicle mal‐
functions:▷Unusual vibrations while driving.▷Unusual handling such as a strong ten‐
dency to pull to the left or right.
Damage can, e. g., be caused by driving over
curbs, road damage, or similar things.
WARNING
Damaged tires can lose tire inflation
pressure, which can lead to loss of vehicle
control. There is risk of an accident. If tire dam‐
age is suspected while driving, immediately re‐
duce speed and stop. Have wheels and tires
checked. For this purpose, drive carefully to
the nearest dealer’s service center or another
qualified service center or repair shop. Have
vehicle towed or transported as needed.◀
WARNING
Damaged tires can lose tire inflation
pressure, which can lead to loss of vehicle
control. There is risk of an accident. Do not re‐
pair damaged tires, but have them replaced.◀
Changing wheels and tires
Mounting Have mounting and wheel balancing carriedout by a dealer’s service center or another
qualified service center or repair shop.
Wheel and tire combination
You can ask the dealer’s service center or an‐
other qualified service center or repair shop
about the right wheel/tire combination and
wheel rim versions for the vehicle.

Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.
Repairing a flat tire
Safety measures▷Park the vehicle as far away as possible
from passing traffic and on solid ground.▷Switch on the hazard warning system.▷Secure the vehicle against rolling away by
setting the parking brake.▷Turn the steering wheel until the front
wheels are in the straight-ahead position
and engage the steering wheel lock.▷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 at an
appropriate distance.
Mobility System
The concept
With the Mobility System, minor tire damage
can be sealed temporarily to enable continued
travel. To accomplish this, sealant is pumped
into the tires, which seals the damage from the
inside.
The compressor can be used to check the tire
inflation pressure.
Information
▷Follow the instructions on using the Mobi‐
lity System found on the compressor and
sealant container.▷Use of the Mobility System may be ineffec‐
tive if the tire puncture measures approx.
1/8 in/4 mm or more.▷Contact a dealer’s service center or an‐
other qualified service center or repair
shop if the tire cannot be made drivable.▷If possible, do not remove foreign bodies
that have penetrated the tire.▷Pull the speed limit sticker off the sealant
container and apply it to the steering
wheel.▷The use of a sealant can damage the TPM
wheel electronics. In this case, have the
electronics checked at the next opportu‐
nity and have them replaced if needed.
DANGER
If the exhaust pipe is blocked or ventila‐
tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases con‐
tain carbon monoxide, an odorless and color‐
less but highly toxic gas. In enclosed areas, ex‐
haust gases can also accumulate outside of
the vehicle. There is danger to life. Keep the
exhaust pipe free and ensure sufficient ventila‐
tion.◀
Storage
The Mobility System is located under the cargo floor panel.
Sealant container
▷Sealant container, arrow 1.▷Filling hose, arrow 2.

Filling the tire with sealant
1.Shake the sealant container.2.Pull the connection hose fully out of the
compressor housing. Do not kink the hose.3.Screw the connection hose onto the con‐
nector of the sealant container.4.Insert the sealant container on the com‐
pressor housing in an upright position.5.Screw the filling hose of the sealant con‐
tainer onto the tire valve of the nonworking
wheel.Seite 174MobilityWheels and tires174

6.With the compressor switched off, insert
the plug into the power socket inside the
vehicle.7.With the ignition turned on or the engine
running, switch on the compressor.
ATTENTION
The compressor can overheat during ex‐
tended operation. There is a risk of damage to
property. Do not run the compressor for more
than 10 min.◀
Let the compressor run for approx. 3 to 8 mi‐
nutes to fill the tire with sealant and achieve a
tire inflation pressure of approx. 2.5 bar.
While the tire is being filled with sealant, the
tire inflation pressure may sporadically reach
approx. 5 bar. Do not switch off the compres‐
sor at this point.
If a tire inflation pressure of 2 bar is not
reached:
1.Switch off the compressor.2.Unscrew the filling hose from the wheel.3.Drive 33 ft/10 m forward and back to dis‐
tribute the sealant in the tire.4.Inflate the tire again using the compressor.If a tire inflation pressure of 2 bar cannot be
reached, contact your dealer’s service cen‐
ter or another qualified service center or
repair shop.
Stowing the Mobility System
1.Unscrew the filling hose of the sealant con‐
tainer from the wheel.2.Unscrew the connection hose of the com‐
pressor from the sealant container.3.Connect the filling hose of the sealant con‐
tainer previously connected to the tire
valve with the available connector on the
sealant container.
This prevents leftover sealant from escap‐
ing from the container.4.Wrap the empty sealant container in suita‐
ble material to avoid dirtying the cargo
area.5.Stow the Mobility System back in the vehi‐
cle.
Distributing the sealant
Immediately drive approx. 5 miles/10 km to en‐
sure that the sealant is evenly distributed in the
tire.
Do not exceed a speed of 50 mph/80 km/h.
If possible, do not drive at speeds less than
12 mph/20 km/h.
To correct the tire inflation pressure
1.Stop at a suitable location.2.Screw the connection hose of the com‐
pressor directly onto the tire valve stem.3.Insert the connector into the power socket
inside the vehicle.4.Correct the tire inflation pressure to
2.5 bar.▷Increase pressure: with the ignition
turned on or the engine running, switch
on the compressor.Seite 175Wheels and tiresMobility175

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.

service center or another qualified service cen‐
ter or repair shop.
Changing wheels/tires General information
When sealants are used, an immediate wheel
change when there is a loss of tire inflation
pressure in the event of a flat tire is unneces‐
sary.
No spare tire is provided with your vehicle.
If needed, the tools for changing wheels are
available as accessories from a dealer’s service
center or another qualified service center or re‐
pair shop.

service life of the battery.
More information about the battery can be re‐
quested from a dealer’s service center or an‐
other qualified service center or repair shop.
Battery replacement ATTENTION
Vehicle batteries that are not compatible
can damage vehicle systems and impair vehi‐
cle functions. There is a risk of personal and
property damage. Only vehicle batteries that
are compatible with your vehicle type should
be installed in your vehicle. Information on
compatible vehicle batteries is available at your
dealer’s service center.◀
