Tools
The jack, wheel wrench, adapters (for
spare wheel removal), hub cap hook
and towing eye are contained in a
unit, stowed under the front seat.
Notice
Depending on vehicle, there may be multiple adapters for spare wheel
removal.

Vehicles with Rear-wheel drive: A
hydraulic jack and a set of extension
pieces for use with the jack are also
included.
To access this unit, slide the seat fully forwards and fold down the backrest.

Wheel changing 3 184.
Spare wheel 3 185.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.
We recommend not swapping the
front wheels with the rear wheels and vice versa, as this can affect vehicle
stability. Always use less worn tyres
on the rear axle.
Tyres Factory-fitted tyres are matched to
the chassis and offer optimum driving comfort and safety.

176Vehicle careWinter tyresWinter 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 maximum speed sticker in the driver's field of view.
Tyre designations

Speed code letter:

Fit directional tyres such that they roll
in the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
The tyre pressure information label
on the driver's door frame indicates
the original equipment tyres and the
correspondent tyre pressures.
Always inflate tyres to the pressures
shown on the label.
Tyre pressures 3 219.
The tyre pressure data refers to cold
tyres. It applies to summer and winter
tyres.
Always inflate the spare tyre to the
pressure specified for full load.Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 201.
2. Identify the respective tyre.
The tyre pressure tables show all possible tyre combinations 3 219.
For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.

178Vehicle careAfter inflating, some driving may be
required to update the tyre pressure
values in the DIC. During this time w
may illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for
approaching a low tyre pressure
condition. Check tyre pressure of all
four tyres.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w flashes for
several seconds then illuminates
continuously together with control
indicator A 3 85 and a
corresponding message appears in
the DIC.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. TPMS is not operational for
these wheels. For the further three
wheels, TPMS remains operational.Control indicator w and the
corresponding message appears at
each ignition cycle until the tyres are
inflated to the correct tyre pressure.
Driver Information Centre (DIC) 3 89.
Vehicle messages 3 90.
Puncture A puncture or severely under-inflated
tyre is indicated by illumination of
control indicator w together with C
3 85 and a corresponding message
appears in the DIC. Stop vehicle and
switch off engine.
Tyre pressure 3 219, Tyre repair kit
3 180, Spare wheel 3 185, Wheel
changing 3 184.
Temperature dependency Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
Tyre pressure values provided on the tyre information label and tyre
pressure chart are valid for cold tyres,
which means at 20 °C. The pressure
increases by nearly 1.5 psi for a10 °C temperature increase. This
must be considered when warm tyres
are checked.
The tyre pressure value displayed in
the DIC shows the actual tyre
pressure. A cooled down tyre will show a decreased value, which does
not indicate an air leak.
Relearn function
After changing the wheels, TPMS
needs to recalculate.
With the vehicle stationary, select the tyre pressure menu in the DIC by
pressing button on end of wiper lever. Press and hold button for approx.

180Vehicle 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.
Tyre chains
Tyre chains are only permitted on the
drive wheels.
On vehicles with twin rear wheels,
tyre chains are only permitted on the
outer wheels.
Always use fine mesh chains that add no more than 15 mm to the tyre tread
and the inboard sides (including chain lock).
9 Warning
Damage may lead to tyre blowout.
Wheel covers on steel wheels may
come into contact with parts of the
chains. In such cases, remove the
wheel covers.
Tyre chains may only be used at
speeds up to 30 mph and, when
travelling on roads that are free of
snow, they may only be used for brief
periods since they are subject to rapid wear on a hard road and may snap.
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 the tyre's sidewall near the rim
cannot be repaired with the tyre repair kit.

184Vehicle careWheel changingSome vehicles are equipped with a
tyre repair kit instead of a spare wheel
3 180.
Make the following preparations and
observe the following information:
● Park the vehicle on a level, firm and non-slippery surface. The
front wheels must be in the
straight-ahead position.
● Apply the parking brake and engage first gear or reverse gear
(manual transmission) or N
(manual transmission
automated).
● Switch off the air suspension system 3 122.
● Remove the spare wheel 3 185.
● Never change more than one wheel at a time.
● 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.
● 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 engine when the vehicle is raised on the jack.
● Clean wheel bolts/nuts and their threads before mounting thewheel.9 Warning
Do not grease wheel bolt, wheel
nut and wheel nut cone.
1. Remove the wheel cover using the hook supplied. Vehicle tools
3 174.
2. Install the wheel wrench ensuring that it locates securely and loosen
each wheel bolt/nut by half a turn.
3. Vehicles with Front-wheel drive:
Raise vehicle by placing lifting
pad spigot of the jack under the
jacking hole located nearest the
wheel concerned.
