344If and when
WARNING (Continued)
● 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 vehicle, 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 result in chemical burns.
Note
The vehicles must not touch each other, otherwise electricity could flow as
soon as the positive terminals are connected.
Towing and tow starting Introduction
When towing, always respect legal requirements.
For technical reasons, it is not possible to tow a vehicle if the battery is flat.
Additional information and warnings:
● Electronic power control and exhaust gases purification system
⇒ page 232
WARNING
A vehicle with a flat battery should never be towed.
● Never remove the key from the ignition lock. The electronic steering
lock could engage. Then the vehicle will be uncontrollable. You may lose
control of the vehicle and there is a risk of serious accident.
WARNING
When towing the vehicle, the handling and braking efficiency change
considerably. Please observe the following instructions to minimise the
risk of serious accidents and injury:
● As the driver of the vehicle being towed:
– The brake must be depressed must harder as the brake servo does
not operate. Always remain aware to avoid collision with the towing
vehicle.
– More strength is required at the steering wheel as the power steer-
ing does not operate when the engine is switched off.
● As the driver of the towing vehicle:
– Accelerate gently and carefully.
– Avoid sudden braking and manoeuvres.
– Brake well in advance than usual and brake gently.
CAUTION
● Carefully fit and remove the towline anchorage and its cover to avoid
damage to the vehicle (for example, paintwork).
● When towing, fuel could enter the catalytic converter and cause dam-
age!
Instructions for tow starting
In general, the vehicle should not be started by towing. Jump-starting is
much more preferable ⇒ page 341.
For technical reasons, the following vehicles can not be tow started:
345
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.
