Miscellaneous situations

Jump start: description

WARNING

Jump start

Worn or dirty windscreen wiper blades re-

duce visibility and increase the risk of acci-

dent and serious injury.

Introduction

If the engine fails to start because of a dis-

charged 12-volt battery, the battery can be

connected to the battery of another vehicle to

start the engine.

●

Always replace damaged or worn wind-

screen wiper blades or blades that no longer

clean the windscreen properly.

Jump leads complying with the DIN 72553

standard are needed for starting (see cable

manufacturer's instructions). The wire cross

section must be at least 25 mm²for petrol en-

gines and at least 35 mm²for diesel engines.

NOTICE

●

Damaged or dirty windscreen wipers could

scratch the glass.

Fig. 163 Wiring diagram for vehicles without a

start/stop system.

●

If products containing solvents, rough

sponges or sharp objects are used to clean

the blades, the graphite layer will be dam-

aged.

NOTICE

To avoid considerable damage to the vehicle

electrical system, note the following care-

fully:

Never use fuel, nail varnish remover, paint

thinner or similar products to clean the win-

dows.

wiper blades are not frozen to the glass be-

fore using the wipers. In cold weather, it may

help to leave the vehicle parked with the wip-

●

Use only jump leads with fully insulated

clamps.

●

Do not allow the vehicles to come into con-

tact with each other, otherwise current may

start to ﬂow as soon as the positive poles are

connected.

(30 miles).

Towing the vehicle

Tow cable and tow bar

Introduction

It is safer for the vehicle to be towed using a tow

bar, avoiding damage to the vehicle. The tow

cable should only be used if a tow bar is not

available.

It takes practice to tow a vehicle, especially

when using a tow cable. Both drivers should be

well informed of the special features of towing.

Inexperienced drivers should refrain from tow-

ing.

●

If the vehicle runs out of power during tow-

ing, stop the process immediately and seek

the assistance of specialised personnel.

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 material.

During towing, make sure at all times that no

inadmissible traction forces or jolts are gener-

ated. On roads without a ﬁrm surface there is

always the danger of overloading the attach-

ment parts.

NOTICE

Towing the vehicle with a tow cable or a tow

bar can cause damage to the vehicle.

Tow with a tow truck

If a breakdown lorry is used, vehicles with au-

tomatic transmission are only allowed to be

towed with the front wheels suspended.

●

If possible, have the vehicle transported on

a tow truck.

Tow start

WARNING

Tow starting means starting a vehicle's engine

while another puts it in motion by pulling it.

During the towing of a vehicle, the driving

behaviour and braking capacity change con-

siderably.

The vehicle can be towed with a tow bar or

cable

Towing

Towing means a vehicle pulling another vehicle

that is not in a condition to run.

254

MisTcoewllianngetohuesvseithuicalteions

If the vehicle cannot be towed on its wheels for

any of the reasons mentioned above, request

assistance from specialised personnel and, if

necessary, have the vehicle transported with-

out the wheels touching the ground.

Instructions for tow-starting and

towing

NOTICE

If the vehicle is pushed by hand, the tail light

units, the side spoilers of the rear window

and large sheet metal surfaces may be dam-

aged. In addition, the rear spoiler could be

detached.

During towing, the change of direction can be

signalled on the towed vehicle even when the

hazard warning lights are on. To do so, at the

same time, the turn signal lever must be oper-

ated with ignition switched on. During this time

the hazard warning lights remain disconnected.

When the turn signal lever is returned to the

rest position, the hazard warning lights will be

automatically reactivated.

Steps to be taken prior to tow starting

Vehicles with an automatic gearbox: Due to

technical reasons, tow starting the vehicle is not

allowed. Attempt to start the engine using the

starting aid ››› page 252.

Cases where tow starting and towing the ve-

hicle are not permitted

Removing and attaching the cover and the

is not recommended to tow start the vehicle. If

the engine does not start, try the starting aid

as a light source. They have been designed to

last the lifetime of the vehicle and the bulbs

cannot be replaced. In case of headlight fail-

●

Depending on weather conditions (cold or

wet), the front lights, the fog lights, the tail

lights and the turn signals may be tempora-

rily misted. This has no inﬂuence on the use-

ful life of the lighting system. By switching on

the lights, the area through which the beam

of light is projected will quickly be demisted.

However, the edges may continue to be mis-

ted.
