Introduction
This chapter contains information on the following subjects:
Jump-starting 165
Jump-starting in vehicles with the START-STOP system 166
The battery of another vehicle can be used to jump-start your vehicle if the en-
gine will not start because the battery is flat. Jump-start cables are required for
this purpose.
Both batteries must have a rated voltage of 12 V. The capacity (Ah) of the battery
supplying the power must not be significantly less than the capacity of the dis-
charged battery in your vehicle.
Jump-start cables
Only use jump-start cables which have an adequately large cross-section and in-
sulated terminal clamps. Observe the manufacturer's instructions.
Positive cable - colour coding in the majority of cases is red.
Negative cable - colour coding in the majority of cases is black. WARNING
■ A discharged vehicle battery may already freeze at temperatures just below
0 °C. In case of frozen battery carry out no jump-starting - risk of explosion! ■ Pay attention to the warning instructions relating to working in the engine
compartment »
page 138, Engine compartment .
■ The non-insulated parts of the terminal clamps must never make contact
with each other. In addition, the jump-start cable connected to the positive
terminal of the battery must not come into contact with electrically conduct-
ing parts of the vehicle - risk of short circuit! ■ Do not clamp the jump-start cable to the negative terminal of the dis-
charged battery. There is the risk of detonating gas seeping out the battery
being ignited by the strong spark which results from the engine being started. ■ Route the jump-start cables so that they cannot be caught by any rotating
parts in the engine compartment. ■ Do not bend over the battery - risk of caustic burns!
■ The vent screws of the battery cells must be tightened firmly. WARNING (Continued)
■ Keep any sources of ignition (naked flame, smouldering cigarettes, etc.)
away from the battery - risk of an explosion! ■ Never jump-start vehicle batteries with an electrolyte level that is too low -
risk of explosion and caustic burns. Note
■ There must not be any contact between the two vehicles otherwise current
may flow as soon as the negative terminals are connected. ■ The discharged battery must be properly connected to the system of the vehi-
cle. ■ We recommend you buy jump-start cables from a car battery specialist. Ð Jump-starting

Attach the other end 4
to a solid metal part which is connected firmly to the
engine block, or to the engine block itself.
Starting engine
› Start the engine on the vehicle providing the power and allow it to idle.
› Now start the engine of the vehicle with the discharged battery.
› If the engine does not start, terminate the attempt to start the engine after
10 seconds and wait for about 30 seconds before repeating the process.
› Disconnect the cables in exactly the
reverse order to the one described above. ÐJump-starting in vehicles with the START-STOP system
Fig. 139
Jump-starting - START-STOP
system
First read and observe the introductory information and safety warn-
ings on page 165.
On vehicles with the START-STOP system, the jump-start cable of the charger
must never be connected directly to the negative pole of the vehicle battery, but
only to the engine earth » Fig. 139. ÐTowing the vehicle
ä
Introduction
This chapter contains information on the following subjects:
Front towing eye 167
Rear towing eye 167
Vehicles with manual transmission can be towed in with a tow bar or a tow rope
or with the front or rear wheels raised.
ä Vehicles with automatic transmission can be towed in with a tow bar or a tow
rope or with the front wheels raised. If the vehicle is raised at rear, the automatic
gearbox is damaged!
A tow bar
is the safest way of towing a vehicle and also minimises any shocks.
Only use a tow rope if a suitable tow bar is not available.
When towing, the following guidelines must be observed.
Driver of the tow vehicle
› Release the clutch particularly gently when starting off or depress the accelera-
tor particularly gently if the vehicle is fitted with an automatic gearbox.
› On vehicles with a manual transmission, only push down on the accelerator
pedal once the rope is taught.
The maximum towing speed is 50 km/h.
Driver of the towed vehicle
› Switch on the ignition so that the steering wheel is not blocked and so that the
turn signal lights, horn, windscreen wipers and windscreen washer system can
be switched on.
› Take the vehicle out of gear or move the selector lever into position
N if the
vehicle is fitted with an automatic gearbox.
Please note that the brake servo unit and power steering only operate if the en-
gine is running. If the engine is not running, significantly more physical force is re-
quired to depress the brake pedal and steer the vehicle.
If using a tow rope, ensure that it is always kept taught. CAUTION
■ Do not tow start the engine - danger of damaging the engine! On vehicles with
a catalytic converter, unburnt fuel may get into the catalytic converter where it
may ignite. This in turn may damage or destroy the catalytic converter. The bat-
tery from another vehicle can be used as a jump-start aid » page 165, Jump-start-
ing .
■ If the gearbox of your vehicle no longer contains any oil because of a defect,
your vehicle must only be towed in with the driven wheels raised clear of the
ground, or on a special vehicle transporter or trailer.
■ The vehicle must be transported on a special vehicle or trailer if it is not possible
to tow in the vehicle in the way described or if the towing distance is greater than
50 km. ■ To protect both vehicles when tow-starting or towing, the tow rope should be
elastic. Thus one should only use plastic fibre rope or a rope made out of a simi-
larly elastic material. £
