248Sunroof light– Carefully remove the lamp, using the flat side of the screwdriver,
as shown in the figure ⇒fig. 179 . – Remove the lamp, moving it in the direction of the arrow and
outwards ⇒fig. 179 .
– Installation is done in the reverse order.
Jump-startingJump leads
The jump lead must have a sufficient wire cross section.If the engine fails to start because of a discharged battery, the battery can be
connected to the battery of anot her vehicle to start the engine.
Jump leads
Jump leads must comply with the standard DIN 72553 (see manufacturer's
documentation). The wire cross section must be at least 25 mm
2 for petrol
engines and at least 35 mm
2 for diesel engines.
Note
•
The vehicles must not touch each other, otherwise electricity could flow as
soon as the positive terminals are connected.
•
The discharged battery must be properly connected to the vehicles elec-
trical system.

How to jump startIn ⇒ fig. 180, the flat battery is and the charged battery .
Jump lead terminal connections
– Switch off the ignition on both vehicles ⇒.
1. Connect one end of the red jump lead to the positive ⇒fig. 180
terminal of the vehicle with the flat battery ⇒.
2. Connect the other end of the red jump lead to the positive terminal in the vehicle providing assistance.
3. Connect one end of the black jump lead to the negative terminal on the battery of the vehicle providing assistance. 4. Connect the other end of the black jump lead to a solid metal
component which is bolted on to the engine block, or onto the
engine block itself of the vehicle with the flat battery. Do not
connect it to a point near the battery ⇒.
5. Position the leads in such a way that they cannot come into contact with any moving parts in the engine compartment.
Starting
6. Start the engine of the vehicle with the boosting battery and let
it run at idling speed.
7. Start the engine of the car with the flat battery and wait one or two minutes until the engine is “running”.
Removing the jump leads
8. Before you remove the jump leads, switch off the headlights (if they are switched on).
9. Turn on the heater blower and rear window heater in the vehicle with the flat battery. This helps minimise voltage peaks that are
generated when the leads are disconnected.
10. When the engine is running, disconnect the leads in reverse order to the details given above.
Connect the battery clamps so they ha ve good metal-to-metal contact with
the battery terminals.
If the engine fails to start, switch off the starter after about 10 seconds and
try again after about half a minute.

WARNING
•
Please note the safety warnings referring to working in the engine
compartment ⇒page 198, “Working in the engine compartment”.
•
The battery providing assistance must have the same voltage as the flat
battery (12V) and approximately the same capacity (see imprint on
battery). Failure to comply could result in an explosion.
•
Never use jump leads when one of the batteries is frozen. Danger of
explosion! Even after 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 away from batteries, danger
of explosion. Failure to comply could result in an explosion.
•
Observe the instructions provided by the manufacturer of the jump
leads.
•
Do not connect the negative cable from the other vehicle directly to the
negative terminal of the flat battery. The gas emitted from the battery could
be ignited by sparks. Danger of explosion.
•
Do not attach the negative cable from the other vehicle to parts of the
fuel system or to the brake line.
•
The non-insulated parts of the battery clamps must not be allowed to
touch. The jump lead atta ched to the positive battery terminal must not
touch metal parts of the vehicle, this can cause a short circuit.
•
Position the leads in such a way that they cannot come into contact
with any moving parts in the engine compartment.
•
Do not bend over the batteries. This could result in chemical burns.Note
The vehicles must not touch each other, otherwise electricity could flow as
soon as the positive terminals are connected.

Towing and tow-startingTo w - s t a r t i n g
The use of jump leads is preferable to tow-starting.We recommend that you do not tow-start your vehicle. Jump-starting
is preferable ⇒page 248.
However, if your vehicle has to be tow-started:
– Engage the 2nd or the 3rd gear.
– Keep the clutch pressed down.
– Switch on the ignition.
– Once both vehicles are mo ving, release the clutch.
– As soon as the engine starts, press the clutch and move the gear lever into neutral. This helps to prevent driving into the towing
vehicle.
WARNING
The risk of accidents is high when tow-starting. The vehicle being towed
can easily collide with the towing vehicle.
Caution
When tow-starting, fuel could enter the catalytic converter and damage it.
Towing eyesPlease observe the following points if you use a tow-rope:

section of the vehicle:

towing eye to the rear of
the vehicle

Notes for the driver of the towing vehicle
– Drive slowly at first until the to w-rope is taut. Then accelerate
gradually.
– Begin and change gears cautiously. If you are driving an auto- matic vehicle, accelerate gently.
– Remember that the brake servo and power steering are not working in the vehicle you are towing. Brake earlier than you
would normally, but with a more gentle pressure on the brake.
Notes for the driver of the towed vehicle
– Ensure that the tow-rope remains taut at all times when towing.
Fitting the towing eye
– Take the towing ring from the onboard tools.
– Pull the lower front cover down and leave the cover hanging on the vehicle.
– Remove the cover of the screw hole, insert a screwdriver into the lower slot and lever gently.
– Screw the towing eye as shown by arrow anti-clockwise to the
limit position in the front ⇒page 251, fig. 181 or rear
⇒ page 251, fig. 182 threaded hole.Tow-rope or tow-bar
It is easier and safer to tow a vehicle with a tow-bar. You should only use a
tow-rope if you do not have a tow-bar.
A tow-rope should be slightly elastic to reduce the loading on both vehicles.
It is advisable to use a tow-rope made of synthetic fibre or similarly elastic
material. Attach the tow-rope or the tow-bar only to the towing eyes provided or a
towing bracket.
Driving style
Towing requires some experience, espec
ially when using a tow-rope. Both
drivers should be familiar with the te chnique required for towing. Inexperi-
enced drivers should not attempt to tow-start or tow away another vehicle.
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 always a risk of over-
loading and damaging the anchorage points.
The ignition of the vehicle being towed must be switched on to prevent the
steering wheel from locking and also to allow the use of the turn signals,
horn, windscreen wipers and washers.
As the brake servo does not work if the engine is not running, you must apply
considerably more pressure to the brake pedal than you normally would.
As the power assisted steering does not work if the engine is not running, you
will need more strength to steer than you normally would.
Towing vehicles with an automatic gearbox
•
Put the selector lever into position “N”.
•
Do not drive faster than 50 km/h when towing a vehicle.
•
Do not tow further than 50 km.
•
If a breakdown vehicle is used, the vehicle must be towed with the front
wheels raised.Note
•
Observe legal requirements when towing or tow-starting.
•
Switch on the hazard warning lights of both vehicles. However, observe
any regulations to the contrary.
•
For technical reasons, vehicles with an automatic gearbox must not be
tow-started.
