Towing and tow-starting the vehicle
General information
Points to observe when tow-starting or towing away If you use a tow rope:
Notes for the driver of the towing vehicle
– The tow rope must be taut before you drive off.
– Release the clutch very carefully when starting the vehicle
(manual gearbox), or accelerate gently (automatic gearbox).
Notes for the driver of the towed vehicle
– The ignition should be switched on so that the turn signals,
horn, windscreen wipers and washers can be used. Please en-
sure that the steering wheel is unlocked when you switch on the
ignition, and that it moves freely.
– Put the gearbox lever in neutral (manual gearbox) or move the
selector lever to position N (automatic gearbox).
– The brake servo only works when the engine is running. Consid-
erably more effort is required on the brake pedal when the en-
gine is switched off.
– Remember that the brake servo only works when the ignition is
switched on and the vehicle is moving 1)
. Otherwise, considera-
bly more strength than usual will be required when steering. –
Ensure that the tow rope remains taut at all times.
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 avoid damage to both vehicles. It is
advisable to use a tow rope made of synthetic fibre or similarly elastic mate-
rial.
Only attach the tow rope or the tow bar to the towing rings ⇒ page 245.
Driving style
Towing requires some experience, especially when using a tow rope. Both
drivers should be familiar with the technique required for towing. Inexper-
ienced 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 always a risk of
overloading and damaging the anchorage points.
WARNING
If the vehicle has no electrical power, the brake lights, turn signals and
all other lights will no longer function. Do not have the vehicle towed
away. Failure to do so could result in an accident.
CAUTION
If there is no oil in the gearbox or no lubricant in the automatic transmission
the car may only be towed with the driven wheels lifted clear of the road, or
transported on a special car transporter or trailer. 

Important: the battery must be correctly charged.

250Fuses and bulbs
–Unlock the fuse cover ⇒ Fig. 132.
– Remove the clips from the fuse cover.
– Use the plastic clip to pull out the fuse and replace the blown
fuse with a fuse of the same rating.
The individual electrical circuits are protected by fuses. Fuses are located
under a cover below the steering wheel on the left side of the engine com-
partment.
WARNING
Do not repair fuses, and never replace a blown fuse with a higher amper-
age fuse. The electrical system could be damaged, with risk of fire.
CAUTION
● Multiple fuse values on the same line (for example, 5/10/20) in the fol-
lowing tables indicate equipment-related differences. Replace the blown
fuse with a fuse of the same amperage.
● If a newly replaced fuse blows again after a short time, the electrical sys-
tem must be checked by a specialised workshop as soon as possible.
Note
● Positions are not occupied by a fuse do not appear in the following ta-
bles.
● Some of the equipment listed in the tables below pertain only to certain
versions of the model or are an optional extra. Fuses in the vehicle interior

The electric windows and electric seats* are protected by circuit breakers.
These switch on again automatically after a few seconds when the overload
(caused for example by frozen windows) has been corrected.

Bulbs
Changing a bulb
Changing bulbs requires a certain degree of practical skill. If you choose to change engine compartment lamps yourself, remember
that it is a dangerous area ⇒ 
in Working on components in the engine
compartment on page 209.
Always use identical bulbs with the same designation. The name can be
found on the base of the bulb holder.
Depending on how equipped the vehicle is, there are different sets of head-
lights and tail lights:
● Halogen headlights
● Full-LED main headlights*
● Rear bulb light
● LED rear light* Full-LED headlight system*
Full-LED headlights handle all light functions (daylight, side light, turn sig-
nal, dipped beam and route light) with light emitting diodes (LEDs) as a
light source.
Full-LED headlights are designed to last the lifetime of the car and light
bulbs cannot be replaced. In case of headlight failure, go to an authorised
workshop to have it replaced.

hicle must be checked. Never fill with incorrect fluids, other-
wise serious damage to the engine may be caused.
