250Vehicle 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 V). Its capacity
(Ah) must not be much less than
that of the discharged vehicle
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 vehicle 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,
automatic transmission in P.
Open the positive terminal protection
caps of both vehicle batteries.
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 boosterbattery.
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. three 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.

Vehicle care251Towing
Towing the vehicle
Press in the middle of the cover plate
and slide to the upper left corner to
unclip it.
The towing eye is stowed with the vehicle tools 3 234.
Screw in the towing eye clockwise as
far as it will go until it stops in a
horizontal position.
Attach a tow rope – or better 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.
Caution
Deactivate the driver assistance
systems like active emergency
braking 3 188, otherwise the
vehicle may automatically brake during towing.
Switch the selector lever to neutral.
Release the parking brake.
Caution
Never tow a vehicle equipped with All Wheel Drive (AWD) with the
front or rear tyres on the road. If
you tow a vehicle equipped with
AWD while the front or rear tyres
are rolling on the road, the drive
system in the vehicle could be
severely damaged. When towing
vehicles equipped with AWD, all
four tyres must not be in contact
with the road.

254Vehicle careDo not clean the engine compartmentwith 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.
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.
Use only water-repellent products
approved for the vehicle.
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 damageRectify minor paintwork damage witha touch-up pen before rust forms.
Have more extensive damage or rust
areas repaired by a workshop.
