Vehicles with tyre repair kit
Some tools and the towing eye are
located together with the tyre repair
kit in a tool box in the load
compartment below the floor cover.
Vehicles with tyre repair kit and
flat load compartment floor
Some tools and the towing eye are
located together with the tyre repair
kit in a bag, which is fixed at the front left lashing eye in the load
compartment.
Wheels and tyres
Wheels
On vehicles with Diesel engines no
steel rims and only special, for this
vehicle approved alloy wheels are
permitted.
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 should
therefore be fitted on all wheels.
All tyre sizes are permitted as winter
tyres 3 236.
Vehicle care203
Use tyre size 225/55 R17 only as
winter tyres.
On vehicles with Diesel engines, no
steel rims and only special, vehicle-
approved alloy wheels are permitted.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.
Tyre designationsE.g. 235/55 R 17 99 V235=Tyre width, mm55=Cross-section ratio (tyre
height to tyre width), %R=Belt type: RadialRF=Type: RunFlat17=Wheel diameter, inches99=Load index e.g. 99 is
equivalent to 775 kgV=Speed code letter
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 mphTyre 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 3 236.
The tyre and loading information label on the left door frame indicates the
original equipment tyres and the
correspondent tyre pressures.
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.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
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 3 231.
2. Identify the respective tyre.
The tyre pressure tables show all possible tyre combinations 3 236.
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.
206Vehicle care
Select:■ Light for comfort pressure up to
3 people
■ Eco for Eco pressure up to
3 people
■ Max for full loading
Auto learn function
After changing wheels, the vehicle
must be stationary for approx.
20 minutes, before the system
recalculates. The following relearn process takes up to 10 minutes of
driving with a minimum speed of
12 mph. In this case, $ can be
displayed or pressure values can
swap in the Driver Information Centre.
If problems occur during the relearn
process, a warning message is
displayed in the Driver Information
Centre.
Temperature dependency Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
The tyre pressure value displayed in
the Driver Information Centre 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.
214Vehicle care
The spare wheel has a steel rim.Caution
The use of a spare wheel that issmaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
Removing the spare wheel and
stowing a damaged wheel in the load compartment
The spare wheel is located in the
spare wheel well beneath the floor
cover.
The spare wheel well is not designed
for other tyre sizes than spare wheel.
To remove: 1. Close the soft top and fold in the load compartment partition by
pushing at the loop area upwards
to the inside 3 71.
2. Remove the floor cover.
3. The spare wheel is secured with a
wing nut in the well. Untwist nut,
remove conus and take out the
spare wheel.
Under the spare wheel there is a
box and a bag with vehicle tools.
4. Change the damaged wheel 3 211 and stow the tools back in
the tool box and the bag. Remove
the strap from the box and put
aside.
5. Secure the tool box by turning right back the wing nut with the
conus. Put the bag in the well.
6. Stow the damaged wheel outside up in the well.
216Vehicle care
positioned as far as possible to
the front. Secure the wheel by
turning the wing nut clockwise.
6. Insert and close floor cover.9 Warning
Storing a jack, a wheel or other
equipment in the load
compartment could cause injury if they are not fixed properly. During a sudden stop or a collision, loose
equipment could strike someone.
Store jack and tools always in the
respective storage compartments
and secure them by fixing.
Damaged wheel placed in the load
compartment must always be
secured by the strap.
Temporary spare wheel
Caution
The use of a spare wheel that is smaller than the other wheels or in combination with winter tyres
could affect driveability. Have thedefective tyre replaced as soon as
possible.
Only mount one temporary spare
wheel. Do not drive faster than
50 mph. Take curves slowly. Do not
use for a long period of time.
If your vehicle gets a flat tyre on the
rear while towing another vehicle,
mount the temporary spare wheel in
the front and the full tyre in the rear.
Tyre chains 3 207.
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.
The following applies to tyres fitted
opposing the rolling direction:
■ Driveability may be affected. Have the defective tyre renewed or
repaired as soon as possible.
■ Drive particularly carefully on wet and snow-covered road surfaces.
Jump starting
Do not start with quick charger.
A vehicle with a discharged vehicle
battery can be started using jump
leads and the vehicle battery of
another vehicle.9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact of the battery with
eyes, skin, fabrics and painted
surfaces. The fluid contains
sulphuric acid which can cause
injuries and damage in the event
of direct contact.
