343
If and when
2. Connect one end of the red jump lead to the positive +
termi-
nal of the vehicle with the flat battery A ⇒ Fig. 219.
3. Connect the other end of the red jump lead to the positive ter-
minal +
in the vehicle providing assistance B.
4. For vehicles without Start-Stop system: Connect one end of the
black jump lead to the negative terminal –
of the vehicle pro-
viding assistance B ⇒ Fig. 219.
– For vehicles with Start-Stop system: Connect one end of the
black jump lead X
to a suitable ground terminal, a solid piece
of metal in the engine block, or to the engine block ⇒ Fig. 220.
5. Connect the other end of the black jump lead X
to a solid met-
al component bolted to the engine block or to the engine block
itself of the vehicle with the flat battery. However, connect it to
a point as far as possible from the battery A
.
6. Position the leads in such a way that they cannot come into contact with any moving parts in the engine compartment.
Starting
7. Start the engine of the vehicle with the boosting battery and let it run at idling speed.
8. Start the engine of the vehicle with the flat battery and wait two or three 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 vehi-
cle with the flat battery. This helps minimise voltage peaks
which are generated when the leads are disconnected.
11.When the engine is running, disconnect the leads in reverse or- der 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 starter after about 10 seconds and
try again after about half a minute.
WARNING
● Please note the safety warnings referring to working in the engine
compartment ⇒ page 281.
● The battery 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 batteries is frozen. Danger of
explosion! Even after 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, dan-
ger of explosion. Failure to comply could result in an explosion.
● 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.

If and when
● Vehicles with an automatic gearbox.
● Vehicles with an electronic parking brake, given that it is possible that
the brake will not be disengaged.
● If the vehicle battery is flat, it is possible that the engine control units do
not operate correctly.
However, if your vehicle must absolutely be tow-started (manual gearbox):
● Engage the 2nd or 3rd gear.
● Keep the clutch pressed down.
● Switch on the ignition and the hazard warning lights.
● Release the clutch when both vehicles are moving.
● As soon as the engine starts, press the clutch and move the gear lever
into neutral. This helps to prevent a collision with the towing vehicle.
CAUTION
When tow-starting, fuel could enter the catalytic converter and damage it.
Towing instructions
Tow rope or tow bar
When towing, the tow bar is the safest and vehicle friendly way. You should
only use a tow rope if you do not have a tow bar.
A tow rope should be slightly elastic to avoid damage to both vehicles. It is
advisable to use a tow rope made of synthetic fibre or similarly elastic mate-
rial.
Only secure the tow rope or tow bar to the towline anchorage or specially
designed fitting.
Vehicles with a factory fitted towing device , can only be used for towing
with a tow bar, specially designed to fit on a tow hitch ball ⇒ page 237.Towing vehicles with an automatic gearbox
Note the following for a towed vehicle:
●
Make sure the gear selector lever is in the N position.
● Do not drive faster than 50 km/h (30 mph).
● Do not tow further than 50 km (30 miles).
● If a breakdown truck is used, the vehicle must be towed with the front
wheels raised. Note the following instructions for towing four all-wheel drive
vehicles.
Instructions for towing all-wheel drive vehicles
All-wheel drive vehicles can be towed using a toolbar or tow rope. If the ve-
hicle is towed with the front or rear axle raised, the engine must be turned
off to avoid transmission damage.
For vehicles with a double clutched DSG ®
(direct shift gearbox) the instruc-
tions for towing vehicles with an automatic gearbox apply ⇒ page 345.
Situations in which the vehicle should not be towed
In the following cases, the vehicle should not be towed but transported on a
trailer or special vehicle:
● If the vehicle gearbox does not contain lubricant due to a fault.
● If the vehicle battery is flat and, as a result, the electronic steering lock
and electronic parking brake cannot be disengaged if applied.
● If the vehicle to be towed has an automatic gearbox and the distance to
be covered is greater than 50 km (30 miles).
Note
The vehicle can only be towed if the electronic parking brake and steering
lock are deactivated. If the vehicle has no power supply or there is an elec-
tric system fault, the engine must be started using jump leads to deactivate
the electronic parking brake and electronic steering lock.

If and when
● Screw in the towline anchorage into its position anticlockwise as far as
it will go ⇒
. Use a suitable tool to firmly tighten the towline anchorage in
its location.
● After towing, remove the towline anchorage by turning it clockwise and
put the cover back in place.
CAUTION
● The towline anchorage must always be completely and firmly tightened.
Otherwise, it could be released while towing and tow-starting.
● Vehicles with a factory fitted towing bracket, can only be used for towing
with a tow bar, specially designed to fit on a tow hitch ball. Otherwise, the
tow hitch ball and the vehicle may be damaged. Otherwise, a tow rope
should be used.
Towing advice
Towing requires some experience, especially when using a tow rope. Both
drivers should be familiar with the technique required for towing. For this
reason, inexperienced drivers should abstain.
While driving, avoid excessive traction forces and jerking. When towing on
an unpaved road, there is always a risk of overloading and damaging the
anchorage points.
If the vehicle is towed, with the hazard warning lights on and the ignition
switched on, the turn signal may be used to indicate changes of direction.
Simply operate the turn signal lever as usual. Meanwhile, the hazard warn-
ing lights will go off. When the turn signal lever is returned to the rest posi-
tion, the hazard warning lights will be turned on automatically. Notes for the driver of the towed vehicle
●
Leave the ignition on to avoid locking the steering wheel, to release the
electronic parking brake and to activate the turn signals, the horn as well as
the window wipers and window washers.
● As the power assisted steering does not work if the engine is not run-
ning, you will need more strength to steer than normally.
● The brake must be depressed must harder as the brake servo does not
operate. Avoid hitting the towing vehicle.
● Note the instructions and information contained in the Instruction Man-
ual for the vehicle to be towed.
Notes for the driver of the towing vehicle
● Accelerate gently and carefully. Avoid sudden manoeuvres.
● Brake well in advance than usual and brake gently.
● Note the instructions and information contained in the Instruction Man-
ual for the vehicle to be towed.
