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 instructions of the jumper lead manufactur-
er.
Positive cable – colour coding in the majority of cases is red.
Negative cable – colour coding in the majority of cases is black.
Jump-starting in vehicles with the START-STOP system
First read and observe the introductory information and safety warn-
ings
on page 243.
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

Vehicles with manual transmission may be towed in with a tow bar or a tow rope
or with the front or rear wheels raised.
Vehicles with automatic transmission may 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 used.
›
Take the vehicle out of gear or move the selector lever into position N if the ve-
hicle 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 – there is a risk of damaging the engine and the
■
catalytic converter. The battery from another vehicle can be used as a jump-start
aid
» page
243, Jump-starting.
If the gearbox no longer contains any oil because of a defect, your vehicle must
■
only be towed with the driven wheels raised clear of the ground or on a special
breakdown vehicle or trailer.
The vehicle must be transported on a special breakdown 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.
