198Vehicle care
Temperature dependencyTyre 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
remains the same.
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.
Vehicle care199
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.
Steel wheels: When using locking
wheel bolts, do not attach wheel
covers.
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
Damage may lead to tyre blowout.
Tyre chains are only permitted on
tyres of size 195/65 R15,
205/55 R16 and 225/45 R17.
Tyre chains are not permitted on tyres of size 225/40 R18.
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 near the rim
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.
Vehicle care205
Make the following preparations and
observe the following information:
■ Park the vehicle on a level, firm and
non-skid surface. The front wheels
must be in the straight-ahead
position.
■ Apply the parking brake and engage first gear, reverse gear or
P .
■ Remove the spare wheel 3 208.
■ 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.
■ Before screwing in the wheel bolts,
clean them and lightly coat the
taper of each wheel bolt with
commercially available grease.9 Warning
Do not grease the thread of the
wheel bolt.
1. Pull off the wheel cover.
For wheel covers with visible
wheel bolts: The cover can remain
on the wheel. Do not remove the
retaining rings on the wheel bolts.
Alloy wheels: Disengage wheel
bolt caps with a screwdriver and
remove. To protect the wheel,
place a soft cloth between the
screwdriver and the alloy wheel.
2. Variant 1:
Install the wheel wrench ensuring
that it locates securely and loosen
each wheel bolt by half a turn.
Variant 2:
Vehicle care209
■Insert the strap through the spokes
of the wheel as shown in the
illustration.
■ Mount the hook to the rear lashing eye.
■ Tighten the strap and secure it using the buckle.
Storing a replaced wheel in the
spare wheel well using an
extension bar Use the extension bar placed in the
tool box. Vehicle tools 3 192.
■ Turn the wing nut anticlockwise and
remove temporary spare wheel.■ Take the extension bar from the tool box and screw it on the bolt.
■ Store the damaged wheel and secure it by turning the wing nut
clockwise.
The floor cover can be placed on the
projecting wheel.
Remove the extension bar before
fitting the spare wheel in the well after
renewing or repairing the defective
wheel.
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.
Store jack and tools always in the
respective storage compartments
and secure them by fixing.
Place the damaged wheel always
in the load compartment secured
by the strap or in the spare wheel
well secured by the wing nut.
Temporary spare wheel
Caution
The use of the temporary spare
wheel could affect driveability.
Have the defective tyre renewed
or repaired as soon as possible.
210Vehicle care
Only mount one temporary spare
wheel. The permissible maximum
speed on the label on the temporary
spare wheel is only valid for the
factory-fitted tyre size.
If your vehicle gets a flat tyre in the
rear while towing another vehicle,
mount the temporary spare wheel in the front and the full tyre in the rear.
Tyre chains 3 199.
Spare wheel with directional tyre
If possible, 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 vehicle battery explosion or
damage to the electrical systems
of both vehicles.
9 Warning
Avoid contact of the vehicle
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 vehicle 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 vehicle
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.
218Service 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 91.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 compliant 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 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
3 222.
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.
