Vehicle care191Tread depthCheck 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.
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
nominal tyre pressure and make
other vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.
Tyre pressure monitoring system
3 189.9 Warning
The use of unsuitable tyres or
wheels may lead to accidents and will invalidate the vehicle
operating permit.
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.

192Vehicle careTyre 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 215/60 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 50 km/h 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 four 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 80 km/h.
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 3 186.
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.

Vehicle care195Seek 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.
Note
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
3 192.
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 3 197.
● 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.
● 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.
● Remove 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.
● Clean wheel bolts / nuts and thread with a clean cloth before
mounting the wheel.9 Warning
Do not grease wheel bolt, wheel
nut and wheel nut cone.
1. Remove the wheel cover (using the hook supplied).
Vehicle tools 3 186.

Vehicle care199● 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.
Note
If present, the additional battery is automatically connected to the main vehicle battery only when the engine
is running. It does not need to be manually disconnected before jump
starting the vehicle.
Vehicle battery 3 172.
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 vehicle 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
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 five 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.

200Vehicle careTowingTowing the vehicle
The towing eye is stowed with the
vehicle tools 3 186.
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 32.
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.
Note
Depending on version, it may be
necessary to switch on the engine to
permit operation of brake lights.
Move the selector lever to neutral.
Release the parking brake.
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.
Switch on hazard warning flashers
3 113.
To prevent the entry of exhaust fumes
from the towing vehicle, switch on the air recirculation system 3 119 and
close the windows.
Seek the assistance of a workshop.
After towing, unscrew the towing eye
and replace cap.
