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.
The built-in safety valve opens at a
pressure of 7 bar.
Note the expiry date of the kit. After
this date its sealing capability is no
longer guaranteed. Pay attention to
storage information on sealant
bottle.
Replace the used sealant bottle.
Dispose of the bottle as prescribed
by applicable laws.
The compressor and sealant can be used from approx. -30 °C.
The adapters supplied can be used
to pump up other items e.g.
footballs, air mattresses, inflatable
dinghies etc. They are located on the
underside of the compressor. To
remove, screw on compressor air
hose and withdraw adapter.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-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 3 198.
■ 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.
■ If the ground on which the vehicle is standing is soft, a solid board
(max. 1 cm thick) should be placed
under the jack.
■ 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.
1. Pull off the wheel cover with the hook. Vehicle tools 3 188.
For wheel covers with visible
wheel bolts: The cover can remain
on the wheel. Do not remove the
retaining rings on the wheel bolts.

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
Disengage cap at bottom and removedownwards.
The towing eye is stowed with the
vehicle tools 3 188.
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
The towing eye must only be used for towing and not for recovering the
vehicle.
Caution
Activate the child lock in both rear
doors if the rear seats are
occupied. Child locks 3 24.
Page 205 of 237

Vehicle care203
Switch on ignition to release steering
wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
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.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation and close the
windows.
Vehicles with automatic transmission: The vehicle must be towed facing
forwards, not faster than 50 mph nor further than 60 miles. In all other
cases and when the transmission is
defective, the front axle must be
raised off the ground.
Seek the assistance of a workshop. After towing, unscrew the towing eye.
Insert cap at the bottom and close
cap.
Towing another vehicle
Disengage the cap at the bottom and
remove downwards.
The towing eye is stowed with the
vehicle tools 3 188.
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
The lashing eye at the rear
underneath the vehicle must never be used as a towing eye.
Attach a tow rope – or even better a
tow bar – to the towing eye.
The towing eye must only be used for
towing and not for recovering a
vehicle.

Vehicle care205
Thoroughly rinse and leather-off the
vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Exterior lights Headlight and other light covers are
made of plastic. Do not use any
abrasive or caustic agents, do not use
an ice scraper, and do not clean them dry.
Polishing and waxing
Wax the vehicle regularly (at the
latest when water no longer beads).
Otherwise, the paintwork will dry out.
Polishing is necessary only if the paint
has become dull or if solid deposits
have become attached to it.
Paintwork polish with silicone forms a
protective film, making waxing
unnecessary.
Plastic body parts must not be treated with wax or polishing agents.Windows and windscreen wiper
blades
Use a soft lint-free cloth or chamois
leather together with window cleaner and insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Clean smearing wiper blades with a
soft cloth and window cleaner.
Moonroof
Never clean with solvents or abrasive
agents, fuels, aggressive media (e.g.
paint cleaner, acetone-containing
solutions etc.), acidic or highly
alkaline media or abrasive pads. Do
not apply wax or polishing agents to
the middle part of the moonroof.
Wheels and tyres
Do not use high-pressure jet
cleaners.Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.
Paintwork damage Rectify minor paintwork damage witha touch-up pen before rust forms.
Have more extensive damage or rust
areas repaired by a workshop.
UnderbodySome areas of the vehicle underbody
have a PVC undercoating while other
critical areas have a durable
protective wax coating.
After the underbody is washed, check
the underbody and have it waxed if
necessary.
Bitumen/rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.
