Emergencies
Jump starting Jump leads The jump lead must have a sufficient wire
cross section.
If the engine fails to start because of a dis-
charged battery, the battery can be connec-
ted to the battery of another vehicle to start
the engine.
Jump leads
Jump leads must comply with standard
DIN
72553 (see cable manufacturer's instruc-
tion s).
The wire cross section must be at least
25 mm 2
for petrol engines and at least
35 mm 2
for diesel engines. Note
● The vehicles must not touch each other,
otherwise electricity could flow as soon as
the positive terminals are connected.
● The discharged battery must be properly
connected to the on-board network. How to jump start: description

8. Start the engine of the vehicle with the flat battery and wait 2 or 3 minutes until the
engine is “running”.
Removing the jump leads
9. Before you remove the jump leads, switch off the dipped beam headlights (if they
are switched on).
10.Turn on the heater blower and heated rear window in the vehicle with the flat battery.
This helps minimise voltage peaks which
are generated when the leads are discon-
nected.
11. When the engine is running, disconnect
the l e
ads in reverse order to the details
given above.
Connect the battery clamps so they have
good metal-to-metal contact with the battery
terminals.
If the engine fails to start, switch off the start-
er after about 10 seconds and try again after
about 1 minute. WARNING
● Please note the safety warnings referring to
working in the engine compartment
››› page 198.
● The b att

ery providing assistance must have
the same voltage as the flat battery (12V) and
approximately the same capacity (see imprint on battery). Failure to comply could result in
an explosion.
●
Never use jump leads when one of the bat-
teries is frozen. Danger of explosion! Even af-
ter the battery has thawed, battery acid could
leak and cause chemical burns. If a battery
freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes
away from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufacturer of the jump leads.
● Do not connect the negative cable from the
other vehicle directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion.
● Do not attach the negative cable from the
other vehicle to parts of the fuel system or to
the brake line.
● The non-insulated parts of the battery
clamps must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot come into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult in chemical burns. Note
The vehicles must not touch each other, oth-
erwise electricity could flow as soon as the
positive terminals are connected. Towing and tow-starting the
vehicle
General information Read the additional information carefully
›››  page 35
Points to observe when tow-starting or tow-
ing away
If you use a tow rope:
Notes for the driver of the towing vehicle
– The tow rope must be taut before you drive
off.
– Release the clutch very carefully when start-
ing the vehicle (manual gearbox), or accel-
erate gently (automatic gearbox).
Driving style
Towing requires some experience, especially
when using a tow rope
. Both drivers should
be f
amiliar with the technique required for
towing. Inexperienced drivers should not at-
tempt to tow.

Advice
Vehicles with towline anchorage
On the right of the rear bumper there is a cov-
er which covers a threaded hole. – Take the towline anchorage out of the vehi-
cle tool set ››› page 220 .
– To r
emove the bumper cover, just press the
upper side of the cover inwards (arrow) and
remo

ve the cover by levering on the lower
››› Fig. 192 side.
– Scr

ew the towline anchorage into the screw
connection as far as it will go ››› Fig. 193
and tighten with the wheel brace.
After use, unscrew the towline anchorage
and put it back in the vehicle tool kit. Replace
the cover on the bumper. The towline anchor-
age should always be kept in the vehicle. WARNING
● If the towline anchorage is not screwed in
as far as the stop, there is a risk of the screw
connection shearing off during towing (acci-
dent risk).
● If your car has a towing bracket, only use
special towing ropes. Risk of accident! CAUTION
In vehicles fitted with a towing bracket, only
use special tow bars to prevent damage to
the ball joint. These tow bars have been spe-
cially approved for use with towing brackets. Tow-starting
As a general rule, tow-starting is not recom-
mended.
– Engage 2nd or 3rd gear before moving off.
– Press the clutch and hold the pedal down.
– Switch the ignition on.
– Once both vehicles are moving, release the
clutch.
– As soon as the engine has started, press
the clutch and move the gear lever to neu-
tral.
If the engine will not start, it is best to try
starting it using the battery of another vehi-
cle ›››
page 223 before attempting to tow
s t

art. You should only try to tow-start the en-
gine if jump starting is not successful. Tow-
starting is an attempt to start the engine via
the movement of the wheels.
When tow-starting a vehicle with a petrol en-
gine
, do not tow it more than a short dis-
tance, otherwise unburned fuel can enter the
catalytic converter. WARNING
The risk of accidents is high when tow-start-
ing, for example, the towed vehicle can easily
be driven into the towing vehicle. CAUTION
Do not tow vehicles for more than 50 km. Risk
of damage to the catalytic converter. Towing vehicles with a manual
gearbox
Towing is relatively straightforward.
Please observe the relevant instructions
››› page 224.
The v

ehicle can be towed using a tow bar or
tow rope in the normal way, with all four
wheels on the road; it can also be towed with
either the front or rear wheels lifted off the
road. The maximum towing speed is 50 km/h
(30 mph).
To

wing a vehicle equipped with
automatic gearbox Certain restrictions must be observed when
towing your vehicle.
Please observe the relevant instructions
››› page 224 .
The v

ehicle can be towed with a tow bar or
tow rope in the normal way, with all four
wheels on the ground. When doing so,
please note the following points:
226

Emergencies
● Make sure the selector lever is in the N
po-
s ition.
● The
vehicle must not be towed faster than
50 km/h (30 mph).
● The v

ehicle must not be towed further than
50 km (30 miles)
. Reason: when the engine
is not running, the gearbox oil pump does
not work and the gearbox is not adequately
lubricated for higher speeds or longer distan-
ces.
If the vehicle has to be towed with a break-
down truck
, it must only be suspended at the
front wheels. Reason: the drive shafts are lo-
cated on the front wheels. If the car is towed
with the rear wheels lifted off the road (I.e.
travelling backwards), the drive shafts also
turn backwards. The planetary gears in the
aut

omatic gearbox then turn at such high
speeds that the gearbox will be severely
damaged in a short time. Note
● If it is not possible to tow the vehicle in the
normal way, or if it has to be towed further
than 50 km (30 miles), it must be transported
on a special car transporter or trailer.
● Should the power supply to the selector
lever be interrupted in position P, the selector
lever will be locked. Before the vehicle can be
recovered/manoeuvred you must manually
release the selector lever ››› page 229. Emergency locking and
unlocking
Introduction The doors, rear lid and panoramic tilting sun-
roof can be locked manually and partially
opened, for example if the key or the central
locking is damaged.
WARNING
Opening and closing doors carelessly can
cause serious injury.
● If the vehicle is locked from outside, the
doors and windows cannot be opened from
the inside.
● Never leave children or disabled people
alone in the car. They could be trapped in the
car in an emergency and will not be able to
get themselves to safety.
● Depending on the time of the year, temper-
atures inside a locked and closed vehicle can
be extremely high or extremely low resulting
in serious injuries and illness or even death,
particularly for young children. WARNING
Getting in the way of the doors and the rear
lid is dangerous and can lead to serious in-
jury.
● Open and close the doors and the rear lid
only when there is nobody in the way. CAUTION
When opening and closing in an emergency,
carefully disassemble components and then
reassemble them carefully to avoid damage
to the vehicle. Locking or unlocking the driver door
Fig. 194
Driver door lever: hidden lock cylin-
der. If the central locking system should fail to op-
erate, the driver door can still be locked and
unlocked by turning the key in the lock.
As a general rule, when the driver door is
locked all other doors are locked. When the
vehicle is unlocked manually, only the driver
door opens. Please observe the instructions
relating to the anti-theft alarm system

gine is warm. Risk of burns.
● Bulbs are highly sensitive to pressure. The
glass can break when you touch the bulb,
causing injury.
● When changing bulbs, please take care not
to injure yourself on sharp edges, in particu-
lar on the headlight housing. CAUTION
● Remove the ignition key before working on
the electric system. Otherwise, a short circuit
could occur. ●
Switch off the lights and the parking light
before changing a bulb.
● Take good care to avoid damaging any com-
ponents. For the sake of the environment
Please ask your specialist retailer how to dis-
pose of used bulbs in the proper manner. Note
● Please check at regular intervals that all
lighting (especially the exterior lighting) on
your vehicle is functioning properly. This is
not only in the interest of your own safety,
but also that of all other road users.
● Before changing a bulb, make sure you
have the correct new bulb.
● Do not touch the glass part of the bulb with
your bare hands, use a cloth or paper towel
instead, since the fingerprints left on the
glass will vaporise as a result of the heat gen-
erated by the bulb, they will be deposited on
the reflector and will impair its surface. 234
