Practical information
Starting assistance
Introduction
If the engine fails to start because of a discharged battery, the battery of an-
other vehicle can be used to start the engine. Before starting, check the
magic eye on the battery ⇒ page 193.
For starting assistance, jump lead cables conforming to the standard
DIN 72553 are required (see the cable manufacturer instructions). The cable
section in vehicles with petrol engine must be at least 25 mm 2
.
Additional information and warnings:
● Working in the engine compartment ⇒ page 180
● Vehicle battery ⇒ page 193
WARNING
Incorrect use of jump leads and incorrectly jump starting could cause the
battery to explode resulting in serious injury. Please observe the follow-
ing rules to minimise the risk of a battery explosion:
● All work involving the vehicle battery and electrical system can cause
corrosion, fire and serious electric shocks. Always read and take into ac-
count the safety warnings and standards before beginning work on the
battery ⇒ page 193, Vehicle battery.
● The battery providing current must have the same voltage (12V) and
approximately the same capacity (see markings on battery) as the flat
battery.
● Never charge a frozen or recently thawed battery. A flat battery can al-
so freeze at temperatures close to 0 °C (+32 °F).
● If a battery is frozen and/or has been frozen then it must be replaced.
WARNING (Continued)
● A highly explosive mixture of gases is released when the battery is
being charged. Always keep lit cigarettes, open flames, sparks and fire
far from the battery. Never use a mobile telephone when connecting and
removing the jump leads.
● Charge the battery only in well ventilated areas given that when the
battery is charged by outside assistance, it creates a mix of highly explo-
sive gases.
● Jump leads should never enter into contact with moving parts in the
engine compartment.
● Never switch the positive and negative poles or connect the jump
leads incorrectly.
● Note the Instruction Manual provided by the manufacturer of the
jump leads.
CAUTION
To avoid considerable damage to the vehicle electrical system, note the fol-
lowing carefully:
● If the jump leads are incorrectly connected, this could result in a short
circuit.
● The vehicles must not touch each other, otherwise electricity could flow
as soon as the positive terminals are connected. 

– Connect one end of the black jump lead to the negative terminal
–
of the vehicle providing assistance B ⇒ Fig. 159.
– 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
.
3. For vehicles with Start-Stop system :
– Connect one end of the red jump lead to the positive +
termi-
nal of the vehicle with the flat battery A ⇒ Fig. 160.
– Connect the other end of the red jump lead to the positive ter-
minal +
in the vehicle providing assistance B.
– 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 en-
gine block ⇒ Fig. 160.
– 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
.
4. Position the leads in such a way that they cannot come into contact with any moving parts in the engine compartment. 

Practical information
Starting
5. Start the engine of the vehicle with the boosting battery and let it run at idling speed.
6. Start the engine of the vehicle with the flat battery and wait one or two minutes until the engine is “running”.
Removing the jump leads
7. Before you remove the jump leads, switch off the headlights (if they are switched on).
8. 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 182.
● 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.
WARNING (Continued)
● 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 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 bend over 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. 

Practical information
Instructions for tow starting
In general, the vehicle should not be started by towing. Jump-starting is
much more preferable ⇒  page 273.
For technical reasons, the following vehicles can not be tow started:
● Vehicles with an automatic gearbox.
● If the vehicle battery is flat, it is possible that the engine control unit
does 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. 
Notes on towing
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 tow ring or specially designed
fitting.
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) when towing a vehicle.
● 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.
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 battery is flat as the steering cannot be unlocked, as a result, the
electronic steering lock and electronic parking brake cannot be disengaged.
● 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 steering lock electronic gearbox lock is
deactivated. If the vehicle has no power supply or there is an electric system
fault, the engine must be started using jump leads to deactivate the steer-
ing column electronic gearbox lock. 

Practical information
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 signals 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
● Keep the ignition running to prevent the steering wheel from locking
and also to allow the use of the turn signals, horn, windscreen wipers and
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. 
