Do not start with quick charger.
A vehicle with a discharged vehicle
battery can be started using jump leads and the vehicle battery of
another vehicle.9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact of the battery with
eyes, skin, fabrics and painted
surfaces. The fluid contains
sulphuric acid which can cause
injuries and damage in the event
of direct contact.
● Never expose the vehicle battery
to naked flames or sparks.
● A discharged vehicle battery can already 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.

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 five minutes, start the other engine. Start attempts should be
made for no longer than 15 s at an interval of 1 min.
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.Towing
Towing the vehicle
Wrap a cloth around the tip of a flat
screwdriver, for example, to prevent
paint damage. Insert the screwdriverin the slot at the lower part of the cap.
Release the cap carefully.

Page 245 of 281

Vehicle care243
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.
Caution
Deactivate the driver assistance
systems like active emergency

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.
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 with the flange into the
recess and fix cap by pushing.

Vehicle care245Appearance 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.
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.
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.
Do 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.
Page 248 of 281

246Vehicle carePlastic body parts must not be treatedwith 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.
Underbody
Some 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.
Liquid gas system9 Danger
Liquid gas is heavier than air and
can collect in sink points.
Take care when performing work
at the underbody in a pit.
For painting work and when using a
drying booth at a temperature above
60 °C, the liquid gas tank must be
removed.
Do not make any modifications to the
liquid gas system.
