Other incidents
The illumination of the warning light can have the following reasons.
▶ The vehicle is loaded on one side. Distribute the load evenly.
▶ The wheels of one axle are loaded more heavily (e.g. when towing a trailer or
when driving uphill or downhill).
▶ Snow chains are mounted.
▶ A wheel has been changed.
CAUTION
Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the warning light can be delayed or does not light up at all.

If there is a fault in the turn signal system, the warning light flashes at twice
its normal rate (does not apply when towing).
When the hazard warning light system is switched on, this will cause all of the turn signal lights as well as both warning lights to flash.

38Operation

›To
use , fold up the cover of the socket in the direction of arrow » Fig. 118 and
plug the electrical appliance plug into the socket.
An automatic deactivation of the socket can take place, for example, for the
following reasons. ▶ Excessive current.
▶ Low state of charge of the battery.
▶ High outlet temperature.
If disabling reasons no longer exist, the automatic activation of the socket can
be done.
Should no automatic activation of the socket take place, the connected devi-
ces must be disconnected from the power outlet and reconnect after a short
time.WARNING■ Make sure that no liquid or moisture enters into the socket - it can be fa-
tal! If fluid does manage to get into the power socket, completely dry out
the socket before reuse.■
The child lock on the power socket is unlocked when using adapters and
extension cables which carry volts – risk of injury!
■
Do no insert any objects (e.g. knitting needles) into the contacts of the
power socket – risk of death!
CAUTION
■ The power socket can only be used for connecting approved electrical acces-
sories with a two-pin 230V plug, with a total power uptake of up to 150 watt.■
The plug of the electrical appliance must be plugged in up to the stop, other-
wise the child safety lock can be unlocked and the socket may be activated but
the electric appliance is still not receiving power.
■
Do not connect bulbs with neon tubes in the socket - there is a risk of dam-
aging the lamp.
■
For appliances with an independent power source (e.g. such as notebooks),
first connect the power source itself and only after that connect the appliance.

Individual electrical circuits are protected by fuses. A blown fuse is recognisa-
ble by the molten metal strip » Fig. 367.
WARNINGAlways read and observe the warnings before completing any work in the
engine compartment » page 278.
CAUTION
■
Replace the faulty fuse with a new one of the same amperage.■If a newly inserted fuse blows after a short time, then seek the assistance of
a specialist garage.■
Do “not repair” the fuses and do not replace them with stronger ones - it can
cause a fire and could damage parts of the electrical system.
Note
■ We recommend always carrying replacement fuses in the vehicle.■There can be several power consuming devices for one fuse. Multiple fuses
may exist for a single power consuming device.Fuses in the dashboard - LHDFig. 368

This chapter contains information on the following subjects:

Change bulb for low beam (halogen headlight)

Replace bulb for main beam and side light switch (halogen headlight)

312
For this reason, we recommend having bulbs replaced by a specialist garage or
seeking other expert help in the event of any uncertainties.
▶ Switch off the ignition and all of the lights before replacing a bulb.
▶ Faulty bulbs must only be replaced with the same type of bulbs. The designa-
tion is located on the light socket or the glass bulb.
We recommend having the headlight settings checked by a specialist garage
after replacing a bulb in the low, high or fog beam.
308Do-it-yourself

In the case of failure of an LED lamp or an LED, visit a specialist garage.WARNING■Always read and observe the warnings before completing any work in the
engine compartment » page 278.■
Accidents can be caused if the road in front of the vehicle is not suffi-
ciently illuminated and the vehicle cannot or can only be seen with difficul-
ty by other road users.
■
H7 and H8 bulbs are pressurised and may burst when changing the bulb -
risk of injury! We therefore recommended wearing gloves and safety
glasses when changing a bulb.
CAUTION
■ Do not take hold of the glass bulb with naked fingers (even the smallest
amount of dirt reduces the working life of the light bulb). Use a clean cloth,
napkin, or similar.■
The cap of the filament bulb must always be seated correctly in the head-
light, otherwise this may allow water and debris to enter the headlight - risk of
damage to the headlights.
Note
■ This Owner's Manual only describes the replacement of bulbs where it is pos-
sible to replace the bulbs on your own without any complications arising. Other
bulbs must be replaced by a specialist garage.■
We recommend that a box of replacement bulbs always be carried in the ve-
hicle.
