The box contains a towing eye and a
tyre repair kit.
Tyre repair kit 3 240.
Wheels and tyres
Tyre condition, wheel condition Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
Winter tyres
Winter tyres improve driving safety at temperatures below 7 °C and should
therefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.
All tyre sizes are permitted as winter
tyres 3 271.Tyre designations
E.g. 225/55 R 18 98 V225:tyre width, mm55:cross-section ratio (tyre height

Choose a tyre appropriate for the
maximum speed of your vehicle.
Refer to the EEC Certificate of
Conformity provided with your vehicle
or other national registration
documents. Optional equipment
could reduce the maximum speed of
the vehicle.

238Vehicle careTyre deflation detection
system
The tyre deflation detection systemcontinually checks the rotation speed
of all four wheels and warns on low
tyre pressure condition once vehicle
is driving. This is achieved by
comparing tyre rolling circumference
with reference values and further
signals.
If a tyre loses pressure the control
indicator q illuminates, a warning
chime is given and a warning
message is displayed in the Driver
Information Centre.
In this case reduce speed, avoid
sharp cornering and strong braking.
Stop at next safe opportunity and
check tyre pressure.
Control indicator q 3 113.
After adjusting tyre pressure initialise
system to extinguish the control
indicator and restart system.Caution
Deflation detection system warns
just about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
In case of a system malfunction, the
control indicators q and R
appear at the same time or a
message is displayed in the Driver
Information Centre. Set correct tyre
pressure and reinitialise system. If the
failure continues to be displayed,
contact a workshop. The system is
inoperable when ABS or ESC has a
malfunction or a temporary spare
wheel is used. Once the road tyre has
been refitted, check the tyre pressure with cold tyres and initialise the
system.
System initialisation
After tyre pressure correction or
wheel change, the system must be
initialised to learn new circumference reference values:
1. Always ensure that all four tyres have correct tyre pressure
3 271.
2. Apply parking brake. 3. Start the initialisation procedure:
a) Vehicles without Infotainment
system: Press button q for 3
seconds. A chime confirms the
start.
b) Vehicles with Infotainment
system: Initialise the deflation
detection system in the vehicle
personalisation 3 123.
4. Reset is confirmed by pop-up indication.

240Vehicle careWheel coversWheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Vehicles with steel wheels: When
using locking wheel nuts, do not
attach wheel covers.
Tyre chains
Tyre chains are only permitted on the
front wheels.
Always use fine mesh chains that add no more than 9 mm to the tyre tread
and the inboard sides (including chain
lock).
9 Warning
Damage may lead to tyre blowout.
Tyre chains are permitted on all tyres
sizes allowed for the vehicle.
Temporary spare wheel
The use of tyre chains is not permitted on the temporary spare wheel.
Tyre repair kit
Minor damage to the tyre tread can be
repaired with the tyre repair kit.
Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that
is at tyre's sidewall cannot be repaired with the tyre repair kit.9 Warning
Do not drive faster than 50 mph.
Do not use for a lengthy period.
Steering and handling may be
affected.
In the case of a flat tyre:
Apply the parking brake and engage
first gear, reverse gear or P.
The tyre repair kit is located in the tool
box underneath the left front seat.
Tool box 3 234.

244Vehicle care3. Pull pipe assembly out slightly,then disconnect connector from
the air hose by turning it a quarter
turn anticlockwise.
4. Remove air hose.
Keep the kit vertical and unscrew
the cartridge from the bottom.
5. To fit the new cartridge and new pipe, carry out these operations in
reverse order.
Wheel changing
Make the following preparations and
observe the following information:
● Park the vehicle on a level, firm and non-skid surface. The front
wheels must be in the straight-
ahead position.
● If necessary, place a chock under
the wheel diagonally opposite the
wheel to be changed.
● Apply the parking brake and engage first gear, reverse gear or
P .
● If the ground on which the vehicle
is standing is soft, a solid board
(max. 1 cm thick) should be
placed under the jack.
● Take heavy objects out of the vehicle before jacking up.
● No people or animals may be in the vehicle when it is jacked-up.
● Never crawl under a jacked-up vehicle.
● Do not start the vehicle when it is
raised on the jack.
● Before screwing in the wheel bolts, clean them.9Warning
Do not grease wheel bolts.
Tightening torques
Caution
If the vehicle is equipped with alloy
wheels, tighten the wheel bolts
manually at least for the first five
turns.
There are two different types of
wheels with two different bolts and tightening torques.
Tightening torque for alloy wheels is
125 Nm.
Page 249 of 289

Vehicle care247Only mount one temporary spare
wheel. The permissible maximum
speed on the label on the temporary
spare wheel is only valid for the
factory-fitted tyre size.
Fitting the spare wheel
Make the following preparations and
observe the following information:
● Park the vehicle on a level, firm and non-skid surface. The front
wheels must be in the straight- ahead position.
● If necessary, place a chock under
the wheel diagonally opposite the wheel to be changed.
● Apply the parking brake and engage first gear, reverse gear or
P .
● Remove the spare wheel 3 245.
● Never change more than one wheel at once.
● Use the jack only to change wheels in case of puncture, not
for seasonal winter or summer
tyre change.
● The jack is maintenance-free.● If the ground on which the vehicle
is standing is soft, a solid board
(max. 1 cm thick) should be
placed under the jack.
● Take heavy objects out of the vehicle before jacking up.
● No people or animals may be in the vehicle when it is jacked-up.
● Never crawl under a jacked-up vehicle.
● Do not start the vehicle when it is
raised on the jack.
● Before screwing in the wheel bolts, clean them.9Warning
Do not grease wheel bolts.
9Warning
Ensure to use always the correct
wheel bolts if changing the
wheels. When installing the spare
wheel, the bolts for alloy wheels can also be used.
● Note that the spare wheel is secured by the conical contact ofeach bolt if the wheel bolts for the
alloy wheels are used. In this
case, the washers do not come
into contact with the spare wheel.
1. Steel wheels with cover: Pull off the wheel cover with the
designated tool 3 234.
Alloy wheels: Disengage wheel
bolt caps with the designated tool
3 234.
