The essentials
Driving style
T o
w
ing requires some experience, especially
when using a tow rope. Both drivers should
realise how difficult it is to tow a vehicle. In-
experienced drivers should not attempt to
tow.
Do not pull too hard with the towing vehicle
and take care to avoid jerking the tow rope.
When towing on an unpaved road, there is al-
ways a risk of overloading and damaging the
anchorage points.
Switch on the ignition so that the turn sig-
nals, windscreen wipers and windscreen
washer can work. Ensure that the steering
wheel is unlocked and moves freely.
Place the gear lever in neutral on vehicles
with a manual gearbox. With an automatic
gearbox, place the lever in N.
To brake, press the brake pedal firmly. The
brake servo does not work when the engine
is switched off.
The power steering only works when the igni-
tion is switched on and the vehicle is moving,
provided that the battery is sufficiently charg-
ed. Otherwise, it will need more force.
Ensure that the tow rope remains taut at all
times. ››› in Instructions for tow-starting on

In general, the vehicle should not be started
by
t

owing. Jump-starting is much more pref-
erable ››› page 43.
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 en

gine control unit does not operate
correctly.
However, if your vehicle must absolutely be
tow-started (manual gearbox):
● Put it into second or third gear.
● Keep the clutch pressed down.
● Switch on the ignition and the hazard warn-
ing lights.
● Rel

ease the clutch when both vehicles are
movin
g.
● As soon as the engine starts, press the
clutc
h and move the gear lever into neutral.
This helps to prevent a collision with the tow-
ing vehicle. How to jump start
Jump lea
ds If the engine fails to start because of a dis-
ch
ar

ged battery, the battery of another vehi-
cle can be used to start the engine. Before
starting, check the magic eye on the battery
›››  page 196.
For starting assistance, jump lead cables con-
forming to the standard DIN 72553 are re-
quired (see the cable manufacturer instruc-
tions). The cable section in vehicles with pet-
rol engine must be at least 25 mm 2
. WARNING
Incorrect use of jump leads and incorrectly
jump st ar

ting could cause the battery to ex-
plode resulting in serious injury. Please ob-
serve the following rules to minimise the risk
of a battery explosion:
● The battery providing current must have
the same v
oltage (12V) and approximately
the same capacity (see markings on battery)
as the flat battery.
● Never charge a frozen or recently thawed
batter
y. A flat battery can also freeze at tem-
peratures close to 0°C (+32°F).
● If a battery is frozen and/or has been frozen
then it mus
t be replaced.
● A highly explosive mixture of gases is re-
lea
sed when the battery is being charged. Al-
ways keep lit cigarettes, flames, sparks and » 43

The essentials
Start the engine of the vehicle with the
fl at
b
attery and wait for 2 or 3 minutes
until the engine is running.
Removing the jump leads Before you remove the jump leads,
switch off the dipped beam headlights if
they are switched on.
Turn on the heater blower and heated
rear window in the vehicle with the flat
battery. This helps minimise voltage
peaks which are generated when the
leads are disconnected.
When the engine is running, disconnect
the leads in reverse order to the details
given above.
Make sure the battery clamps have sufficient
metal-to-metal contact with the battery termi-
nals.
If the engine fails to start after about 10 sec-
onds, switch off the starter and try again after
about 1 minute. WARNING
● Ple a

se note the safety warnings referring to
working in the engine compartment
›››  page 187.
● The battery providing assistance must have
the same v
oltage as the flat battery (12V) and
approximately the same capacity (see imprint 8.

on battery). Failure to comply could result in
an exp
lo

sion.
● Never use jump leads when one of the bat-
teries
is frozen. Danger of explosion! Even af-
ter 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
awa
y from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufact
urer of the jump leads.
● Do not connect the negative cable from the
other vehic
le directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion.
● Never attach the negative cable to fuel sys-
tem component
s or the brake lines in the oth-
er vehicle.
● The non-insulated parts of the battery
clamp
s must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot c
ome into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult
in chemical burns. Note
The vehicles must not touch each other, oth-
erw i

se electricity could flow as soon as the
positive terminals are connected. Changing the wiper blades
