Caution  
Never attempt to “repair” a fuse or replace it by fitting a fuse with a  
higher rating - risk of fire! It could also cause damage to other parts  
of the electrical system.  
Changing a fuse  
If a fuse has blown it must be replaced.  
Note  
If a newly replaced fuse blows again after a short time, the electrical  
system must be checked by a qualified workshop as soon as  
possible.  
Fuses on the driver's side  
Fig. 241 Left side of  
dash panel: Fuse cover  
– Identify the fuse for the failed component.  
– Switch off the ignition and the component concerned.  
– Remove the fuse box cover ⇒ fig. 241.

drive vehicle)  
– Replace the blown fuse (which will have a melted metal  
strip) with a new fuse of the same amp rating.  
Some of the items listed are only fitted on certain models or are  
optional extras.  
The various electrical circuits are protected by fuses. The fuse boxes  
are located behind covers on the left and right sides of the dash  
panel and in the compartment on the right side of the boot.  
Please note that the following list, while correct at the time of  
printing, is subject to alterations. If discrepancies should occur,  
please refer to the sticker on the inside of the fuse cover for the  
correct information for your vehicle.  
A plastic clip for removing the fuses is provided in the fuse cover on  
the left side of the dash panel. There is also a sticker listing the fuses  
in each of the fuse boxes in the dash panel.

Bulbs with a bayonet fastener  
WARNING (continued)  
• Incorrect handling of the high-voltage element of xenon gas-  
Bulbs with a bayonet fastener must be changed as follows:  
discharge bulbs* can have potentially fatal consequences.  
Removing the bulb  
• When changing bulbs, please take care not to injure yourself on  
sharp edges, in particular on the headlight housing.  
– Lightly press the defective bulb into the bulb holder, then  
turn it anti-clockwise and remove it.  
Caution  
– Do not touch the glass part of the new bulb with your  
bare hands, use a cloth or paper towel instead.  
• Always remove the ignition key before carrying out any work on  
the electrical system - danger of short circuiting!  
• Switch off the lights or parking lights before you change a bulb.  
• Take good care to avoid damaging any components.  
• Removing the lights in particular can lead to the paintwork  
becoming damaged. This is another reason why we recommend  
having the bulbs changed by a qualified workshop.  
Fitting the bulb  
– Fit the new bulb, pressing it into the bulb holder, and turn  
it clockwise as far as it will go.  
– If necessary, use a cloth to remove any fingerprints from  
the glass part of the bulb.  
For the sake of the environment  
Please ask your specialist retailer how to dispose of used bulbs in  
the proper manner.  
Bulb holders with a bayonet fastener  
Note  
Place the parts you have removed on a soft cloth so that they do not  
become scratched.  
• Please check at regular intervals that all lighting (especially the  
exterior lighting) on your vehicle is functioning properly. This is not  
only in the interest of your own safety, but also in that of all other  
road users.  
• Before changing a bulb, make sure you have the correct new  
bulb.  
Fig. 245 Diagram: Bulb  
holder with a bayonet  
fastener  
• Do not touch the glass part of the bulb with your bare hands, use  
a cloth or paper towel instead. Otherwise, the fingerprints left on  
the glass will vaporise as a result of the heat generated by the bulb,  
be deposited on the reflector and impair its surface.

is correctly installed, check that it is aligned flush with adjacent  
body parts (such as the wing panel).  
Ensure that the rubber cap is seated correctly so that no water can  
enter the unit.  
Changing bulb for front fog lights
