248Vehicle careChanging tyre and wheel
size If tyres of a different size than thosefitted 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.
Tyre 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

■ Never change more than one wheel
at once.
■ 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.
■ Take heavy objects out of the vehicle before jacking up.
■ 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 vehicle when it is raised on the jack.
■ Clean wheel nuts and thread with a
clean cloth before mounting the
wheel.9 Warning

nut and wheel nut cone.
1. Disengage wheel nut caps with a screwdriver and remove. Pull off
the wheel cover. Vehicle tools
3 242.
Alloy wheels: Disengage wheel
nut caps with a screwdriver and
remove. To protect the wheel,
place a soft cloth between the
screwdriver and the alloy wheel.
2. Fold out the wheel wrench and install ensuring that it locates
securely and loosen each 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 care257
4. Insert the strap through thespokes of the wheel as shown in
the illustration.
5. Mount the hook to the rear left 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.
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, looseequipment could strike someone.
Always store jack and tools 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
The use of the temporary spare wheel
could affect driveability. Have the
defective tyre renewed or repaired as soon as possible.
Only mount one temporary spare
wheel. Do not drive faster than
80 km/h. 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 3 248.
Spare wheel with directional tyre
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.
258Vehicle careJump startingDo not start with quick charger.
A vehicle with a discharged battery
can be started using jump leads and the 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 battery can alreadyfreeze 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.
■ The vehicles must not come into contact with each other during the
jump starting process.■ Apply the parking brake, transmission in neutral, automatictransmission in P.
■ Open the positive terminal protection caps of both batteries.
Lead connection order:
1. Connect the red lead to the positive terminal of the booster
battery.
2. Connect the other end of the red lead to the positive terminal of the
discharged battery.
266Service and maintenance
Confirmations
Confirmation of service is recorded in the Service and Warranty Booklet.The date and mileage is completed
with the stamp and signature of the servicing workshop.
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 3 105.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
ageing 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 have to be used.
Recommendations for gasoline
engines are also valid for
Compressed Natural Gas (CNG),
Liquified Petroleum Gas (LPG) and
Ethanol (E85) fuelled engines.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 270.
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.
