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.
Tyre chains
Tyre chains are only permitted on the
front wheels.
Always use fine mesh chains that add no more than 15 mm to the tyre tread
and the inboard sides (including chain lock).
For tyre size 215/65 R16, consult a
workshop.
9 Warning
Damage may lead to tyre blowout.

Replace the used sealant bottle.
Dispose of the sealant bottle as
prescribed by applicable laws.
Wheel changing
Some vehicles are equipped with a
tyre repair kit instead of a spare wheel 3 154.
Make the following preparations and
observe the following information:
■ Park the vehicle on a level, firm and
non-slippery surface. The front wheels must be in the straight-ahead position.
■ Apply the parking brake and engage first gear or reverse gear.
■ Remove the spare wheel 3 158.
■ Never change more than one wheel
at a time.
■ Use the jack only to change wheels
in case of puncture, not for a
seasonal winter or summer tyre
change.
■ 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 engine when the vehicle is raised on the jack.
1. Remove the wheel cover (using the hook supplied). Vehicle tools
3 148.
2. Loosen each of the wheel bolts by
half a turn using the wheel
wrench. Ensure the wrench
locates securely. The wrench
should turn anticlockwise to
loosen the bolts. Invert the wrench if necessary.
3. Place lifting pad spigot of the jack
under the jacking hole located
nearest the wheel concerned.
Ensure the jack is positioned
correctly. The jack base must be
on the ground directly below the
jacking hole in a manner that
prevents it from slipping.
4. Install wrench onto the jack and raise the vehicle by turning the
wrench until the wheel is clear of
the ground.

158Vehicle care
5. Unscrew wheel bolts completelyby turning anticlockwise and wipe
clean with a cloth.
Put wheel bolts somewhere
where the threads will not be
soiled.
6. Change the wheel. Spare wheel 3 158.
7. Screw in the wheel bolts.
8. Lower the vehicle and remove jack.
9. Tighten each of the wheel bolts in
a crosswise sequence using the
wheel wrench. Ensure the wrench
locates securely. The wrench
should turn clockwise to tighten
the bolts. Invert the wrench if
necessary.
Tightening torque is 160 Nm.
10. Replace the wheel cover, ensuring that the valve hole in thewheel cover is aligned with the
tyre valve before installing.11. Stow the replaced wheel 3 158
and the vehicle tools 3 148.
12. Have the new wheel balanced on the vehicle.
Check the tyre pressure of the
installed tyre 3 178.
Check the wheel bolt torque.
Have the defective tyre renewed or
repaired as soon as possible.
Spare wheel
Some vehicles are equipped with a tyre repair kit instead of a spare wheel 3 154.
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.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.
It may be necessary to jack the
vehicle up to gain access to the spare
wheel on a fully loaded vehicle with a
flat rear tyre.

160Vehicle care
■ A discharged vehicle battery canalready 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 vehicle 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 thejump starting process.■ Apply the parking brake, transmission in neutral.
■ Open the positive terminal protection caps of both batteries.
The battery is located in the engine
compartment.
Remove cover to access the battery.
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.
3. Connect the black lead to the negative terminal of the booster
battery.
4. Connect the other end of the black
lead to a vehicle grounding point,
such as the engine block or an
engine mounting bolt. Connect as

far away from the discharged
vehicle battery as possible,
however at least 60 cm.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump start.
2. After 5 minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of
1 minute.
3. Allow both engines to idle for approx. 3 minutes with the leads
connected.
4. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle
Release cap by using a screwdriver.
The towing eye is stowed with the
vehicle tools 3 148.
Screw the towing eye fully into the
front towing point.
Attach a tow rope - or better still a tow
rod - to the towing eye, never to the
bumper or front suspension units.
Caution
Do not tow the vehicle from the
rear. The front towing eye must
only be used for towing and not
recovering a vehicle.
Caution
Activate the child locks in the rear
doors if the rear seats are
occupied. Child locks 3 28.
Switch on ignition to release steering
wheel lock and to permit operation of
brake lights, horn and windscreen
wipers.
Transmission in neutral.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
Page 164 of 189

162Vehicle care
To prevent the entry of exhaust fumesfrom the towing vehicle, switch on the
air recirculation system and close the windows.
Seek the assistance of a workshop.
After towing, unscrew the towing eye and replace cap.
Towing another vehicle
The fixed towing eye is located under the rear bumper.
Attach a tow rope - or better still a tow
rod - to the rear towing eye, never to
the rear axle and suspension units.
The rear towing eye must only be
used for towing and not recovering a
vehicle.Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
Trailer hitch 3 129.
Appearance care
Exterior care LocksThe locks are lubricated at the factory
using a high quality lock cylinder
grease. Use de-icing agent only when absolutely necessary, as this has a
degreasing effect and impairs lock
function. After using de-icing agent,
have the locks regreased by a
workshop.
Washing The paintwork of your vehicle is
exposed to environmental influences.
Wash and wax your vehicle regularly.
When using automatic vehicle
washes, select a programme that
includes waxing.
Bird droppings, dead insects, resin,
pollen and the like should be cleaned
off immediately, as they contain
aggressive constituents which can
cause paint damage.
