168Vehicle care
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.
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).
Vehicle care169For tyre size 215/60 R17, consult a
workshop.9 Warning
Damage may lead to tyre blowout.
Wheel covers on steel wheels may
come into contact with parts of the
chains. In such cases, remove the
wheel covers.
Tyre chains may only be used at
speeds up to 30 mph and, when
travelling on roads that are free of
snow, they may only be used for brief
periods since they are subject to rapid wear on a hard road and may snap.
The use of tyre chains is not permitted on the temporary spare wheel.
Tyre repair kit Minor damage to the tyre tread or
sidewall 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 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 the vehicle has a flat tyre:
Apply the parking brake and engage
first gear or reverse gear.
The tyre repair kit is located under the
driver's seat. Vehicle tools 3 163.
1. Remove the compressor and sealant bottle from the tyre repairkit case.
2. Remove the electrical connection cable and air hose from the
compartments on the underside
of the compressor.3. Screw the air hose to the connection on the sealant bottle.
4. Fit the sealant bottle into the retainer on the compressor.
Set the compressor near the tyre
in such a way that the sealant
bottle is upright.
5. Unscrew valve cap from defective
tyre.
Vehicle care171Drain excess tyre pressure with
the button beside the pressure
indicator.
Do not run the compressor for
longer than 15 minutes.
13. Detach the tyre repair kit.
14. Remove any excess sealant using a cloth.
15. Take the label indicating maximum permitted speed from
the tyre repair kit and affix in the driver's field of view.
16. Store the sealant bottle in the plastic bag. Return tyre repair kit
to case and stow under the driver's seat.17. Continue driving immediately so that the sealant is evenlydistributed throughout the tyre.
After driving approx. 6 miles, but
no more than 10 minutes, stop
and check tyre pressure using the
compressor. Screw air hose from
compressor directly onto tyre
valve when doing this.
18. If the tyre pressure is more than 2.2 bar (220 kPa/31 psi), set it to
the correct value. Repeat the
procedure until there is no more
loss of pressure.
If the tyre pressure has fallen
below 2.2 bar (220 kPa/31 psi),
the vehicle must not be driven.
Seek the assistance of a
workshop.
19. Detach the tyre repair kit, return to
case and stow under the driver's
seat.9 Warning
Do not allow the sealant to contact
skin, eyes or clothing. If swallowed seek medical assistance
immediately.
Notice
The driving characteristics of the
repaired tyre is severely affected,
therefore have this tyre replaced.
If unusual noise is heard or the
compressor becomes hot, turn
compressor off for at least
30 minutes.
Pay attention to storage information
and expiry date on sealant bottle. Its
sealing capability is not guaranteed
after this time.
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
3 169.
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.
Vehicle care175● 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
the jump 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 (1) of the booster
battery.
2. Connect the other end of the red lead to the positive terminal (2) of
the discharged battery.
3. Connect the black lead to the negative terminal (3) of the
booster battery.
4. Connect the other end of the black
lead to a vehicle grounding point
(4), such as the engine block or an
engine mounting bolt. Connect as
176Vehicle carefar 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 The towing eye is stowed with thevehicle tools 3 163.
Release cap using a suitable tool.
Screw the towing eye clockwise into
the front towing point and tighten fully
using the wheel wrench.
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 29.
Switch on ignition to permit operation
of brake lights, horn and windscreen
wipers, and move the steering wheel
slightly to release the steering wheel
lock.
Transmission in neutral.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
Vehicle care177When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust fumes
from the towing vehicle, switch on the
air recirculation system 3 104 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.

Appearance care
Exterior care
Locks The locks are lubricated at the factoryusing a high quality lock cylinder
grease. Use de-icing agent only when absolutely necessary, as this has adegreasing effect and impairs lockfunction. After using a 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. Restrictions for
filmed or matt painted body parts or decor tapes, see "Polishing and
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.
Service and maintenance183Engine oil viscosity grades
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade depending on the minimum ambient
temperature 3 186.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only silicate-free long life coolant (LLC) antifreeze approved for thevehicle. Consult a workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C.
This concentration should be
maintained all year round. The use of additional coolant additives that
intend to give additional corrosionprotection or seal against minor leaks
can cause function problems. Liability
for consequences resulting from the
use of additional coolant additives will be rejected.
Brake fluid
Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should therefore be replaced at the specified interval.
AdBlue Only use AdBlue to reduce the
nitrogen oxides in the exhaust
emission 3 123.
