Jump-starting
Before starting the engine
If
necessary,
the engine can be started by con­
necting it to the battery of another vehicle.
If the engine fails to start because of
a
dis­
charged battery, the vehicle battery can be
con­

nected to the battery of another vehicle to start
the engine. Suitable jump leads are required.
Both vehicle batteries must be rated at 12 V. The
capacity (Ah) of the booster battery should not
be significantly lower than that of the discharged
battery.
Jump leads
The jump Leads must be heavy enough to carry
the starter current. Refer to the details given by
the manufacturer.
Only
use
jump leads with insulated battery
clamps.
Positive cable - usually red.
Negative cable - usually black.
WARNING
- When it is discharged the vehicle battery
can freeze at temperatures around 0°C. A
frozen vehicle battery must first be thawed
out before connecting the jump leads - risk
of explosion and chemical burns! After
jump-starting the vehicle, drive to a quali­
fied workshop without delay and have the
vehicle battery checked.
- The engine compartment is a potentially
hazardous area and working here can lead
to serious injuries. Before carrying out any
work in the engine compartment please
read and observe the warnings
*page
295.
- Incorrect handling of the jump leads may
result in the vehicLe battery exploding (risk
of serious injury). Please observe the follow­
ing rules to minimise the risk of injury:
- The non-insulated parts of the battery
clamps must not be allowed to touch. The
jump lead attached to the positive terminal
must not touch metal parts of the vehicle:
this can cause short circuiting.
- Position the jump leads in such a way that
they cannot come into contact with any
moving parts in the engine compartment.
- Do not lean over the vehicle battery - risk of
chemical burns!
- The screw plugs on the battery cells must be
screwed in firmly.

If one of the axles has to be raised in order to
tow the vehicLe, please refer to the following ta­
ble to determine the appropriate axle
for
your
gearbox/drive combination:
Manual
gearbox
Automatic
gearbox
Front-wheel
drive
Front or rear
axle
Front axle
Four-wheel
drive
Front or rear
axle
Front axle
Applies to vehicles with four-wheel drive: If the
vehicle is to be towed with one of the axles

raised,
the ignition must be switched off; other­
wise the drive train can be damaged.
Notes on tow-starting
Applies to vehicles with automatic gearbox: For
technical reasons, your vehicle must not be tow-

started.

Applies to vehicles with manual gearbox: As a
general rule, tow-starting is not recommended.
If the engine will not start, it is best to try start­
ing it using the battery of another vehicle

*>page
326 before attempting to tow start. If
this is not possible, you can try to push-start or
tow-start the vehicle
*page
330, Tow-starting.
A WARNING
There is a high risk of accidents when towing/
tow-starting, as the towed vehicle can easily
be driven into the towing vehicle.

UTION

- If it is not possible to tow the vehicle as de­
scribed above (e.g. due to a gearbox failure
or if the vehicle has to be towed further
than 50 km), it must be transported on a
special car transporter or trailer.
- Towing a vehicle with the wrong axle raised
can cause serious damage to the gearbox.
- Applies to vehicles with automatic gearbox:
It is not possible to move the selector lever
out of position
P
if the electrical power sup­
ply fails. Before the vehicle can be recov­
ered/manoeuvred you must manually re­
lease the selector lever; left-hand drive
vehicles
*page
93, right-hand drive

towing anchorages provided
for
this purpose

opage
330,
*page
331.
• Please ensure that the tow-rope is not twisted
as it could otherwise unscrew the towline an­
chorage while the vehicle is being towed.
• The hazard warning lights of both vehicles
must normally be switched on
*page
52. How­
ever, observe any regulations to the contrary.
Towing vehicle (front)
• Ensure that the tow-rope is taut before you
drive off.
• Manual gearbox: Engage the clutch very gently
when starting to move and accelerate with par­
ticular care.
• Automatic gearbox: Accelerate slowly and
grad­

ually.
• Avoid unnecessary braking and manoeuvres.
Vehicle being towed (rear)
• Ensure that the ignition is switched on, the
steering wheel is not locked, and
that
you can
operate the turn signals, horn or windscreen
wipers if necessary

Mobility
the ignition is on and the vehicle is moving1'.
Otherwise you will need to press the brake
ped­

al significantly harder and apply more force to
move the steering wheel.
• Please ensure that the steering wheel is un­
locked and that it moves freely.
• Release the parking brake
*page
82.
• Applies to vehicles with manual gearbox: Put
the gear lever in neutral.
• Applies to vehicles with automatic gearbox:
Move the selector lever to position N.
• Ensure that the tow-rope remains taut at all
times when towing.
© CAUTION
A WARNING
If the vehicle has no electrical power, do NOT
use a tow-bar or tow-rope to tow the vehicle
© Note
You can use the turn signals to indicate a
change of direction (or lane) even when the
hazard warning lights are on. The hazard
warning lights will be interrupted temporari-

Ly.

Tow-starting
Please observe the important safety warnings on

*page
328.
Important: Your vehicle must be fitted with a
manual gearbox. If your vehicle has a petrol en­

gine,
it must not be towed further than 50 me­
tres
*(J).

• Attach the tow-rope or the tow-bar only to the
towing anchorages provided
for
this purpose

*page
330,
*
page 331.
• Engage second or third gear before moving off.
• Press the clutch and hold the pedal down.
• Switch on the ignition.
• Once both vehicles are moving, release the

clutch.

• As soon as the engine starts, press the clutch
pedal and put the gear lever in neutral.
