Several warning and control lamps should light up for a few seconds when
the ignition is sw
itched. This signals that the lamp is working properly. They
will switch off after a few seconds.
Checking the bulbs of a trailer
For vehicles with the factory fitted trailer system, certain trailer lights are al-
so controlled if the socket is correctly connected.
A fault on a trailer turn indicator is indicated on the instrument panel by the
indicator blinking twice as fast ( or ) ⇒ page 95.
● General fault of all indicators on one side.
● Fault in one tail light (on some models, also the registration light).
● Fault in two brake lights. WARNING
If the warning lamps and messages are ignored, the vehicle may stall in
traffic, or m a
y cause accidents and severe injuries.
● Never ignore the warning lamps or text messages.
● Stop the vehicle safely as soon as possible. CAUTION
Failure to heed the warning lamps and text messages when they appear
ma y
result in faults in the vehicle. Note
A fault in the LED on the tail lights will not be indicated. However, if the fault
affects al
l the LEDs then this will be indicated by the indicator . Information for replacing bulbs Checklist
To r
ep
lace a bulb, carry out the following operations always in the order giv-
en ⇒ :
Park the
vehicle a safe distance from traffic and on suitable ground.
Connect the electronic parking brake ⇒ page 183.
Turn the light switch to position 0 ⇒ page 95.
Move the gear lever into the neutral position ⇒ page 95.
Automatic gearbox: Move selector lever to position P ⇒ page 174.
Stop the engine and remove the key from the ignition ⇒ page 170.
Manual gearbox: Select a gear ⇒ page 174.
Wait until all of the passenger compartment lights are turned off
⇒ page 95.
Allow the corresponding bulb to cool. Visually inspect fuses to see if any are blown ⇒ page 322.
Replace the bulb according to the instructions ⇒ . Bulbs should only
be rep l
aced by new identical models. Bulb information is displayed on
the bulb socket or on the bulb itself.
In general, never touch the bulb glass directly. The heat of the bulb
would cause the fingerprint to evaporate and condense on the reflector.
This will impair the brightness of the headlight.
Check if the new bulb is working. If the bulb is not working, it may not
have been correctly fitted, it could be damaged or the connector may
not be correctly connected.
Every time a bulb for the headlights is replaced, visit a specialised
workshop to check the headlights.
