Tools
Vehicles with spare wheel Open the floor cover of the load
compartment 3 72.
Remove the cover of the tool box.
The jack, the towing eye, chocks and
the tools are located in the tool box.
234Vehicle care3. Connect the black lead to thenegative terminal of the booster
battery.
4. Connect the other end of the black
lead to a vehicle grounding point
of your vehicle in the engine
compartment.
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.
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
Remove the cap.
The towing eye is stowed with the
vehicle tools 3 219.
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.
Switch on ignition to release steering
wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Vehicle care235Caution
Deactivate the driver assistance
systems like active emergency
braking 3 170, otherwise the
vehicle may automatically brake during towing.
Switch 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.
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 80 km/h nor further than 100 km. 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 with the flange into the
recess and fix cap by pushing.
Towing another vehicle
Remove the cap.
The towing eye is stowed with the
vehicle tools 3 219.
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 better still a tow
rod – to the towing eye.
The towing eye must only be used for towing and not for recovering a
vehicle.
236Vehicle careCaution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
After towing, unscrew the towing eye.
Insert cap with the upper flange into
the recess and fix cap by pushing.
Appearance care
Exterior care LocksThe locks are lubricated at the factoryusing a high quality lock cylinder
grease. Use a de-icing agent only
when absolutely necessary, as this
has a degreasing effect and impairs
lock function. After using a de-icing
agent, have the locks regreased by a
workshop.
WashingThe 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.If using a vehicle wash, comply with
the vehicle wash manufacturer's instructions. The windscreen wiperand rear window wiper must be
switched off. Remove antenna and
external accessories such as roof
racks etc.
If you wash your vehicle by hand,
make sure that the insides of the
wheel housings are also thoroughly
rinsed out.
Wax painted parts of the vehicle regularly.
Clean edges and folds on opened
doors and the bonnet as well as the
areas they cover.
Clean bright metal mouldings with a
cleaning solution approved for
aluminium to avoid damages.Caution
Always use a cleaning agent with
a pH value of 4 to 9.
Do not use cleaning agents on hot surfaces.
Vehicle care237Do not clean the engine compartment
with a steam-jet or high-pressure jet
cleaner.
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.
Have the door hinges of all doors
greased by a workshop.
Do not use hard objects to remove
spots of tar. Use tar removal spray on painted surfaces.
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 wiper blades
Switch off wipers before handling in
their areas.
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.
Remove dirt residues from smearing
wiper blades by using a soft cloth and window cleaner. Also make sure to
remove any residues such as wax,
insect residues and similar from the
window.Ice residues, pollution and continuous
wiping on dry windows will damage or
even destroy the wiper blades.
Glass panel
Never clean with solvents or abrasive
agents, fuels, aggressive media e.g.
paint cleaner, acetone-containing
solutions, acidic or highly alkaline
media or abrasive pads.
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 with
a touch-up pen before rust forms.
Have more extensive damage or rust areas repaired by a workshop.
