204Vehicle care
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.
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.
Vehicle care205Tyre chains
Use tyre chains only on front wheels.
Tyre chains are permitted on tyres of
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).
9 Warning
Damage may lead to tyre blowout.
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.
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 box under the
floor cover in the load compartment.
Vehicle care209
■ Do not start the vehicle when it israised on the jack.
■ Clean wheel nuts and thread with a
clean cloth before mounting the
wheel.9 Warning

remove. To protect the wheel,
place a soft cloth between the
screwdriver and the alloy wheel.
Alloy wheels with centre wheel
bolt cap: Disengage centre cap by
inserting and pulling the extractor
3 199 in the recess of the brand
emblem.
2. Install the wheel wrench ensuring that it locates securely and looseneach wheel nut by half a turn.
The wheels might be protected by
locking wheel nuts. To loosen
these specific nuts first attach the key adapter onto the head of the
nut before installing the wheel
wrench. The key adapter is
located in the glovebox.
Vehicle care213
9. Insert the strap through thespokes of the wheel as shown in
the illustration.
10. Mount the hook to the right rear lashing eye.
11. Tighten the strap and secure it using the buckle.
12. Deposit the floor cover on the wheel.
13. If equipped, secure coupling ball bar in the bag at a lashing eye in
the load compartment.
14. Fold out the load compartment partition before opening the soft
top.
Stowing the spare wheel back in
the well after replacing the
damaged wheel
1. Close the soft top and fold in the load compartment partition.
2. Remove floor cover, untwist and remove wing nut and conus.
3. Stow the tools in the tool box and the bag.
4. Place spare wheel outside up in the well.
5. Insert and turn the excentricconus in the recess of the spare
wheel so that the wheel is
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
214Vehicle carecould 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 3 205.
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.
■ Never expose the battery to naked flames or sparks.
■ A discharged vehicle battery can already freeze at a temperature of
0 °C. Defrost the frozen battery
before connecting jump leads.
■ Wear eye protection and protective
clothing when handling a battery.
■ Use a booster battery with the same voltage (12 Volts). Its
capacity (Ah) must not be much less than that of the discharged
battery.
■ Use jump leads with insulated terminals and a cross section of at
least 16 mm 2
(25 mm 2
for diesel
engines).
■ Do not disconnect the discharged battery from the vehicle.
■ Switch off all unnecessary electrical
consumers.
■ Do not lean over the battery during jump starting.
■ Do not allow the terminals of one lead to touch those of the other
lead.
222Service and maintenance
Make sure that the Service and
Warranty Booklet is completed
correctly as continuous proof of
service is essential if any warranty or goodwill claims are to be met, and is
also a benefit when selling the
vehicle.
Service interval with remaining
engine oil life duration The service interval is based on
several parameters depending on
usage.
The service display lets you know
when to change the engine oil.
Service display 3 85.Recommended fluids,
lubricants and parts
Recommended fluids and lubricants Only use products that meet the
recommended specifications.
Damage resulting from the use of
products not in line with these
specifications will not be covered by
the warranty.9 Warning
Operating materials are
hazardous and could be
poisonous. Handle with care. Pay
attention to information given on
the containers.
Engine oil
Engine oil is identified by its quality
and its viscosity. Quality is more
important than viscosity when
selecting which engine oil to use. The oil quality ensures e.g. engine
cleanliness, wear protection and oil
aging control, whereas viscosity
grade gives information on the oil's
thickness over a temperature range.
Dexos is the newest engine oil quality
that provides optimum protection for gasoline and diesel engines. If it is
unavailable, engine oils of other listed qualities must be used.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 226.
Topping up engine oil
Engine oils of different manufacturers
and brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use of engine oil with only
ACEA A1/B1 or only A5/B5 quality is
prohibited, since it can cause long-
term engine damage under certain
operating conditions.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 226.
