Variant 3: 4-door notchback
The jack and the tools are in the tool
box below the spare wheel in the load
compartment. The wheel wrench, the towing eye and an extension bolt for
securing a damaged wheel (only
vehicles with temporary spare wheel)
are in the tool bag located in the spare wheel well near the tool box. Spare
wheel 3 272.
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 attemperatures below 7 °C and shouldtherefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.
OPC Version: Tyres of size 235/45
R18 are only permitted as winter tyres.Tyre designations

Directional tyres
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.

Vehicle care263
Temperature dependencyTyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
The tyre pressure value displayed in
the DIC shows the actual tyre
pressure. Therefore it is important to
check tyre pressure with cold tyres.
Tread depth Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and
rear wheels periodically. Ensure that
the direction of rotation of the wheels
is the same as before.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel
size
If tyres of a different size than those
fitted at the factory are used, it may be necessary to reprogramme the
speedometer as well as the nominal
tyre pressure and make other vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
Wheel covers
Wheel 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.

264Vehicle care
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, the wheel
covers might not be attached to the
steel wheels.
Tyre chains
Use tyre chains only on front wheels.
9 Warning
Damage may lead to tyre blowout.
5-door hatchback, 4-door notchback

and the inboard sides (including chain
lock).

size 225/55 R 17. Always use fine
mesh chains that add no more than
10 mm to the tyre tread and the
inboard sides (including chain lock).
Tyre chains are also permitted on
tyres of size 245/45 R 18. Always use fine mesh chains that add no more
than 7 mm to the tyre tread and the
inboard sides (including chain lock).OPC Version

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 80 km/h.
Do not use for a lengthy period.
Steering and handling may be
affected.
If you have a flat tyre:
Apply the parking brake and engage
first gear, reverse gear or P.
The tyre repair kit is in a compartment under the floor cover in the load
compartment or, on version with rear
carrier system, in the drawer under
the passenger seat 3 62.The illustrations show different
versions.

Vehicle care273
To remove:1. Open the floor cover.
2. Only 3-door hatchback: remove rear storage by pressing both
buttons. Fold down cover and
extract storage upwards.
3. The spare wheel is secured with a
wing nut. Untwist nut, remove
conus (only 3-door hatchback) to
take out the spare wheel.
Under the spare wheel there is the box with vehicle tools.
4. When, after a wheel change, no wheel is placed in the spare wheel
well, secure the tool box by
turning right back the wing nut and close floor cover.
Stowing a damaged full size wheel in the load compartment,3-door and 5-door hatchback
The spare wheel well is not designed for other tyre sizes than the spare
wheel. A damaged full size wheel
must be stowed in the load
compartment and secured with a
strap. Vehicle tools 3 256. To secure
the wheel:
1. Position the wheel outside up close to one sidewall of the load
compartment.
2. Place the loop end of the strap through the front lashing eye on
the appropriate side.
3. Place the hook end of the strap through the loop and pull it until
the strap is fastened securely to
the lashing eye.

274Vehicle care
4. Insert the strap through thespokes of the wheel as shown in
the illustration.
5. Mount the hook to the rear lashing
eye.
6. Tighten the strap and secure it using the buckle.
9 Danger
Always drive with folded up and
engaged rear seat backrests when stowing a damaged full size wheel
in the load compartment.
Stowing a damaged full size
wheel in the spare wheel well,
Sports Tourer and 4-door
notchbackVehicles equipped with a full size
spare wheel:
A damaged full size wheel must be
stowed outside up in the spare wheel
well secured with the wing nut.
The floor cover can be placed on the
projecting wheel.
Vehicles equipped with a temporary
spare wheel:
Secure a damaged full size wheel
outside up with the wing nut in the spare wheel well after exchanging the
thread bolt by an extension bolt,
placed in the tool bag 3 256. To
replace the bolt:
1. Install the hexagon key of the wheel wrench ensuring that it
locates securely on the bolt.
2. Turn the wheel wrench anticlockwise to loosen the bolt.
Remove the bolt.
