chamber of the box in the load
compartment 3 64.On version with subwoofer box, the
tools and the towing eye are located
together with the tyre repair kit and
the warning triangle in the box below
the floor cover. To gain access,
remove floor cover: fold rear part to
the front and pull out the cover to the
rear 3 66.
Vehicles with spare wheel
The jack, the wheel bolt wrench, the
tools and two straps for securing a
damaged wheel are in the tool box below the load compartment floor
cover 3 66.

Vehicle care175Wheels and tyresTyre 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.
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.Tyre designations
E.g. 195/55 R 16 95 H195=tyre width, mm55=cross-section ratio (tyre height
to tyre width), %R=belt type: RadialRF=type: RunFlat16=wheel diameter, inches95=load index e.g. 95 is equivalent

Speed code letter:
Q=up to 100 mphS=up to 112 mphT=up to 118 mphH=up to 130 mphV=up to 150 mphW=up to 168 mph
Directional tyres
Directional tyres must be mounted so
that they rotate in the correct
direction. The proper rotation
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.
Unscrew the valve cap.
Tyre pressure 3 214.
The tyre pressure information label
on the right door frame indicates the original equipment tyres and the
correspondent tyre pressures.

Press the MENU button to select the
Vehicle Information Menu X.
Turn the adjuster wheel to select the
tyre pressure monitoring system.
System status and pressure warnings
are displayed by a message with the
corresponding tyre flashing in the
Driver Information Centre.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 87.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 214.
If w flashes for 60-90 seconds and
then illuminates continuously, there is
a fault in the system. Consult a
workshop.
After inflating, driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after driving, this
could be an indicator for getting low
pressure. Check tyre pressure.
Vehicle messages 3 96.
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
illuminates continuously.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these tyres. Control indicator w
illuminates. For the further three tyres the system remains operational.

178Vehicle care
The use of commercially-availableliquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced, tyre pressure monitoring system sensors
must be dismounted and serviced.
For the screwed sensor; replace
valve core and sealing ring. For the
clipped sensor; replace complete
valve stem.
Vehicle loading status Adjust tyre pressure to load condition according tyre information label or
tyre pressure chart 3 214, and select
the according setting in the menu Tire
Load in the Driver Information Centre,
Vehicle Information Menu 3 89.
Select:
■ Light for comfort pressure up to
3 people.
■ Eco for Eco pressure up to
3 people.
■ Max for full loading.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code must be matched to a new tyre/
wheel position after rotating the tyres
or exchanging the complete wheel set
and if one or more TPMS sensors
were replaced. The TPMS sensor
matching process should also be
performed after replacing a spare tyre with a road tyre containing the TPMS
sensor.
The malfunction light and the warning
message or code should go off at the
next ignition cycle. The sensors are
matched to the tyre/wheel positions,
using a TPMS relearn tool, in the
following order: left side front tyre,
right side front tyre, right side rear tyre and left side rear tyre. The turn light
at the current active position is
illuminated until sensor is matched.
Consult your workshop for service or
to purchase a relearn tool. There are
two minutes to match the first tyre/
wheel position, and five minutes
overall to match all four tyre/wheel
positions. If it takes longer, the
matching process stops and must be
restarted.
The TPMS sensor matching process is:
1. Apply the parking brake.
2. Turn the ignition on.

Vehicle care181Tyre chains
Tyre chains are only permitted on the
front wheels.
Always use fine mesh chains that add no more than 10 mm to the tyre tread
and the inboard sides (including chain lock).
9 Warning
Damage may lead to tyre blowout.
Tyre chains are only permitted on
tyres of size 175/70 R 14,
185/70 R 14, 185/60 R 15,
185/65 R 15 and 195/55 R 16.
Tyre chains are not permitted on tyres of size 215/45 R 17 and 225/35 R 18 .
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 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.
If you have a flat tyre:
Apply the parking brake and engage
first gear.
The tyre repair kit is in the tool box
under the floor cover in the load
compartment.

Spare wheel If mounting a spare wheel, which is
different from the other wheels, this
wheel might be classified as a
temporary spare wheel and the
corresponding speed limits apply,
even though no label indicates this.
Seek the assistance of a workshop to
check the applicable speed limit.
The spare wheel has a steel rim.
Caution
The use of a spare wheel that is smaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
The spare wheel is located in a holder
beneath the vehicle floor.
1. Open the load compartment floor 3 66.
Remove storage box if equipped
3 64.
2. Remove the wheel wrench from the tool box.

3. Fit the wheel wrench on thehexagon bolt near the tool box
and turn it anticlockwise until a
resistance is noticeable.
4. Lift the spare wheel holder slightly
by hand and unhook the catch.
5. Lower the spare wheel holder.
6. Lift the spare wheel holder slightly
by hand and detach the safety
cable.
7. Lower holder all the way and remove spare wheel.
8. Change the wheel 3 185.
The damaged wheel must be
secured in the load compartment,
see below.
9. Lift the empty spare wheel holder and insert the safety cable.
10. Lift the spare wheel holder farther
and engage in catch. The open
side of the catch must point in the direction of travel.
