The warning lights in the instrument cluster indicate the status of certain
functions or the presence of faults.
Some warning lights can be accompanied by acoustic signals and messages in
the display of the instrument cluster if required.
After switching on the ignition, some warning lights light up briefly as a func-
tion test. If the tested systems are OK, the corresponding warning lights extin-
guishes for a few seconds after switching on the ignition or after starting the
engine.
WARNING■ Ignoring light-up indicator lamps in the instrument cluster and the control
symbols in the display may cause serious injury or damage to the vehicle.■
If you have to stop for technical reasons, then park the vehicle at a safe
distance from the traffic, switch off the engine and activate the hazard
warning light system » page 52. Place the warning triangle at the prescri-
bed distance.
■
The engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en-
gine compartment » page 120, Engine compartment .
Handbrake

on page 32 first.
lights up – the hand brake has been applied.
An audible warning is also given if you drive the vehicle for at least 3 seconds
at a speed of more than 6 km/h.
Braking system
Read and observe
on page 32 first.
lights up - the brake fluid level in the brake system is too low or there is an
ABS fault.
▶ Stop the vehicle, switch off the engine, and check the level of the brake fluid
» page 125 .
WARNING■
If the warning light lights up at the same time as warning light
» page 34 , Anti-lock braking system (ABS) , do not continue your
journey! Seek help from a specialist garage.■
A fault to the ABS system or the braking system can increase the vehi-
cle's braking distance – risk of accident!
Front seat belt warning light
Read and observe
on page 32 first.
lights up - the driver or front passenger has not fastened their seat belt.
At a speed of over 20 km/h the warning light flashes and an audible warning
sounds at the same time.
The warning signal is switched of and the indicator light is permanently lit if
the driver and front passenger have not fastened their seat belts within the
next 90 seconds.
Alternator
Read and observe
on page 32 first.
lights up – the battery is not being charged whilst the engine is running.
32Using the system
▶Seek help from a specialist garage.
Disconnecting the vehicle battery
If the vehicle's battery has been disconnected and reconnected, the warning
light comes on after switching on the
ignition.
The warning light should go out after driving a short distance.
If, after a short drive, the indicator light does not go out, there is a system er-
ror.
▶ Seek help from a specialist garage.
Other incidents
The following reasons can explain the warning light being illuminated.
▶ The vehicle is loaded on one side. Distribute the load evenly.
▶ The wheels of one axle are loaded more heavily (e.g. 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 in the instrument cluster can be delayed or does
not light up at all.

An acoustic warning signal will sound when the driver's door is opened if the
lever is not in the middle position after removing the ignition key from the igni-
tion lock. The acoustic warning signal will stop just as soon as the driver's door
is closed. 50Using the system
Automatic driving light controlFig. 40
Light switch: AUTO position
The light switch is in position
» Fig. 40 then depending on the equipment
the automatic switch on / off the lights corresponding to the light or weather
conditions (rain) takes place.
Automatic driving light control during rain
The daytime running lights are switched on automatically if the following con-
ditions are met.
The light switch is in the position .
The windscreen wipers are on for more than 15 s.
The light turns off automatically about 4 minutes after turning off the wipers.
CAUTION
Poorer visibility is evaluated by a sensor mounted below the windscreen in the
holder of the rear-view mirror. Do not cover the sensor - the system function
can be disrupted.

If the vehicle is not fitted with fog lights, the rear fog light is switched on by
pulling out the light switch to the only possible setting.
The fog lights/rear fog light are switched off in the reverse order.
COMING HOME / LEAVING HOME
The function COMING HOME ensures that the vehicle's environment is illumi-
nated after switching off the ignition and opening the driver's door.
The function LEAVING HOME ensures that the vehicle's environment is illumi-
nated after unlocking the vehicle with the radio remote control unit.
The function switches the light on only if there is poorer visibility and the light
switch is in the position .
Switching on the COMING HOME function
›
Switch off the ignition and press the control lever briefly to position
» page 50
.
After closing the door or the boot lid, the light remains on for another 15 s.
CAUTION
■ Poorer visibility is evaluated by a sensor mounted below the windscreen in
the holder of the rear-view mirror. Do not cover the sensor - the system func-
tion can be disrupted.■
If this option is always enabled, then the battery is heavily loaded.
51Lights and visibility
The system can, for example, be affected in the following situations or not
be available. ▶ When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
▶ Driving around “sharp” bends.
▶ When fully pressing down the accelerator pedal.
▶ When the laser sensor is dirty or obscured.
▶ When the vehicles are very dirty and have a low level of reflection.
If the system is not available or there is a system malfunction, the message
and the warning light appears on the display of the instrument cluster
flashes in a slow sequence.WARNINGDo not cover the windscreen in the area of the laser sensor. This can lead
to impaired function of the sensor - risk of accidents!WARNINGThe laser beam from the laser sensor can cause serious eye injuries. The la-
ser beam is not visible to the human eye.■
Never use optical devices, e.g. a range-finder camera or magnifying glass
to look into the laser sensor.
■
The laser beam can also be active when the system is disabled or is not
available.
CAUTION
■ Remove any snow from the windscreen in the area of the laser sensor using
a hand brush and any ice with a solvent-free de-icing spray.■
If the laser sensor range on the windscreen has scratches, cracks, etc., re-
place the windscreen.
Note
■ If an automatic brake intervention is triggered by the system, the pressure in
the brake system increases and the brake pedal cannot be operated with the
normal pedal stroke.■
Automatic braking interventions by the emergency brake function can be ter-
minated by pressing the clutch or the accelerator or by moving the steering
wheel.

147Fuses and light bulbs
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 or high beam unit or the fog lamp.
Visit a specialist garage if an LED diode is faulty.WARNING■ Always read and observe the warnings before completing any work in the
engine compartment » page 120.■
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.
■
Bulbs H4, HB4 and H7 are pressurised and may burst when changed –
There is a 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.
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.
