Note
If it is not possible to tow the vehicle as described above, or if it has
to be towed further than 50 km, it must be transported on a special
car transporter or trailer.Towing a vehicle with automatic gearbox and four-wheel drive
Certain restrictions must be observed when towing your
vehicle.Please observe the notes ⇒page 295.
The vehicle can be towed with a towbar or towrope in the normal
way, with all four wheels on the ground. When doing so, please note
the following points:•
Release the parking brake ⇒page 121.
•
Make sure the selector lever is in the N position.
•
The vehicle must not be towed faster than 50 km/h.
•
The vehicle must not be towed further than 50 km. The reason
for this is: when the engine is not running, the gearbox oil pump
does not work and the gearbox is not adequately lubricated for
higher speeds or longer distances.
The vehicle must not be towed with the wheels lifted at either the
front or rear.Note
If it is not possible to tow the vehicle as described above, or if it has
to be towed further than 50 km, it must be transported on a special
car transporter or trailer.

Fuses and bulbs 304BulbsChanging bulbs
Changing bulbs requires a certain degree of practical
skill.You can change the following bulbs for exterior lights yourself:•
Halogen headlights: Bulb for dipped headlights
•
Halogen headlights: Bulb for main beam headlights
•
Bulb for fog light
•
Bulbs for rear lights in boot lid
•
Bulbs for rear lights in side panel
•
Bulbs for number plate light
The following bulbs should only be changed by a qualified work-
shop:
•
Halogen headlights: Bulb for turn signals
•
Halogen headlights: Bulb for side lights
•
Xenon headlights*: Bulb for turn signals
•
Xenon headlights*: Light source for daytime running
lights/parking lights
•
Bulb for headlights: Bi-xenon lights ⇒
•
Light source for turn signal in exterior mirror housing
•
Light source for high-level brake light
As a rule, you require a certain degree of practical skill to change
defective bulbs. This applies in particular to those bulbs which are
only accessible from the engine compartment.
If in doubt, we recommend that you have defective bulbs changed
by a qualified workshop or qualified mechanic.
If you do decide to change bulbs in the engine compartment your-
self, be aware of the safety risks involved ⇒page 255 ⇒.
Types of bulbs
You must only replace a bulb with a bulb of the same type. Informa-
tion regarding e.g. the wattage can be found on the base of the
bulb.

WARNING
•
Take particular care when working on components in the
engine compartment if the engine is warm - risk of burns!
•
Bulbs are sensitive to pressure. The glass can break when you
touch the bulb, causing injury.
•
Incorrect handling of the high-voltage element of xenon gas-
discharge bulbs* can have potentially fatal consequences.
•
When changing bulbs, please take care not to injure yourself on
sharp edges, in particular on the headlight housing.Caution
•
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.For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in
the proper manner.
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.
•
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.
Bulbs with a bayonet fastenerBulbs with a bayonet fastener must be changed as follows:
Removing the bulb
– Lightly press the defective bulb into the bulb holder, then
turn it anti-clockwise and remove it.
– Do not touch the glass part of the new bulb with your
bare hands, use a cloth or paper towel instead.
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.
