WARNING
•
The non-insulated parts of the terminal clamps must never make contact
with each other. Furthermore, the cable connected to the positive terminal of the battery must not come into contact with electrically conducting parts of the vehicle - risk of a short circuit!•
Do not affix the jump starting cables to the negative terminal of the
discharged 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.
•
Run the jump-start cables so that they cannot be caught by any rotating
parts in the engine compartment.•
Do not bend over the batteries - risk of caustic burns!
•
The vent screws of the battery
cells must be tightened firmly.
•
Keep any sources of ignition (naked
flame, smouldering
cigarettes etc.)
away from the battery - risk of an explosion!•
Never jump-start the batteries which have a too low electrolyte level - risk
of explosion and caustic burns!Tow-starting and towing vehicleGeneralPlease pay attention to the following instru
ctions if you are going to use a tow rope:
Driver of the towing vehicle– Do not drive off until
the tow rope is taught.
– Release the clutch particularly gently wh
en starting off or depress the accelerator
particularly gently if yo
ur vehicle is fitted wi
th an automatic gearbox.
Driver of the towed vehicle– Switch the ignition on so that the steer
ing wheel is not blocked and you can also
operate the turn signal lights, the headlight flasher, the windscreen wipers and windscreen washer system.
– Take the vehicle out of gear or move the selector lever into position
N if your
vehicle is fitted with an automatic gearbox.
– Note that the brake servo unit and power steering only operate if the engine is
running. You will require significantly greater physical force to depress the brake pedal and to steer the vehicle
if the engine is not running.
– Ensure that the tow rope is always kept taught. Tow rope or tow bar A tow
bar
is safest way of towing a vehicle and also minimizes any shocks. You can use
a tow
rope
only if a suitable tow bar is not available.
The tow rope must be elastic to protect the
vehicle. Thus one shou
ld only use plastic
fibre rope or a rope made out
of a similarly elastic material.
Only attach the tow rope to the
towing eyes
provided for this purpose
⇒page 231
and
⇒page 231.
Driving style Towing another vehicle requires a certain am
ount of practice. Both drivers should be
familiar with the particular points about to
wing a vehicle. Unskilled drivers should not
attempt to tow in another vehicle or to be towed in. One should be constantly vigilant not to
allow impermissibly high
towing forces or
jerky loadings. There is always a risk of excessive stresses and damage resulting at the points to which you attach the tow rope or
tow bar when you attempt to tow a vehicle
which is not standing on a paved road.
Caution
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.
Note
•
Please comply with any national legal provisions particularly regarding the
switched on signal systems, when towi
ng in or tow-starting another vehicle.
•
The tow rope must not be twisted as it may in certain circumstances result in the
front towing eye being unscrewed out of your vehicle.
