WARNING
If the warning lamps and messages are ignored, the vehicle may stall in
traffic, or may cause accidents and severe injuries.
● Never ignore the warning lamps or text messages.
● Stop the vehicle safely as soon as possible.
● Park the vehicle at a suitable distance away from the traffic ensuring
that the exhaust system is not in contact with inflammable material, for
example, dry grass, fuel, oil, etc.
● A faulty vehicle represents a risk of accident for the driver and for oth-
er road users. If necessary, switch on the hazard warning lamps and put
out the warning triangle to advise other drivers.
CAUTION
Failure to heed the control lamps and text messages when they appear may
result in faults in the vehicle.

Air conditioning
Instructions for use of the air conditioner
The interior cooling system only works when the engine is running and fan
is switched on.
The air conditioner operates most effectively with the windows and the pan-
oramic sliding sunroof closed. However, if the vehicle has heated up after
standing in the sun for some time, the air inside can be cooled more quickly
by opening the windows and the panoramic sliding sunroof briefly.
Setting for conditions of optimal visibility
When the air conditioning is switched on, the temperature and the air hu-
midity in the vehicle interior drop. Hence, when the outside air humidity is
high, the windows do not mist over and comfort for the vehicle occupants is
improved:
With manual air conditioning
● Switch off air recirculation.
● Set the fan to the required setting.
● Turn the temperature control to the centre position.
● Open and direct all the air outlets in the dash panel.
● Turn the air distribution control to the required position.
● Press the button
to switch on the cooling system. The button will
light up.
With Climatronic
● Press button
.
● Set the temperature to +22 °C (+72 °F).
● Open and direct all the air outlets in the dash panel.
Climatronic: change the temperature unit on the screen of the radio or on
the factory-fitted navigation system
Changing the temperature display from Celsius to Fahrenheit on radio or on
the factory-fitted navigation system is done using the menu on the instru-
ment panel ⇒ page 73. The cooling system cannot be activated
If the air conditioning system cannot be switched on, this may be caused by
the following:
●
The engine is not running.
● The fan is switched off.
● The air conditioner fuse has blown.
● The outside temperature is lower than approximately +3 °C (+38 °F).
● The air conditioner compressor has been temporarily switched off be-
cause the engine coolant temperature is too high.
● Another fault in the vehicle. Have the air conditioner checked by a speci-
alised workshop.
Special Characteristics
If the humidity and temperature outside the vehicle are high, condensation
can drip off the evaporator in the cooling system and form a pool under-
neath the vehicle. This is normal and does not indicate a leak!
Note
After starting the engine, any residual humidity in the air conditioner could
mist over the windscreen. Switch on the defrost function as soon as possi-
ble to clear the windscreen of condensation.

200Driver assistance systems
Overtaking
When the turn signal comes on before overtaking, the ACC accelerates the
vehicle automatically and thus reduces the distance between it and the ve-
hicle ahead.
When you move into the overtaking lane, if the ACC does not detect any ve-
hicle in front it accelerates until it reaches the stored speed and keeps it
constant.
The acceleration can be interrupted at any time by stepping on the brake
pedal or pulling back on the lever ⇒ page 193.
Driving through a bend
On entering or coming out of a bend, the radar sensor may no longer detect
the vehicle ahead of it or may react before a vehicle in the adjacent lane
⇒ Fig. 136 A. In such situations the vehicle may brake unnecessarily or may
cease to react with regard to the vehicle ahead. In this case, the driver has
to act by accelerating or interrupting the braking process by stepping on the
brake pedal or pulling the third lever backwards ⇒ page 193.
Driving in tunnels
When going through tunnels, the radar sensor function may be limited.
Switch off the ACC in tunnels.
Narrow vehicles or vehicles not driving straight
The radar sensor can only detect narrow vehicles or those that are not driv-
ing straight within its range ⇒ Fig. 136 B. This is particularly applicable to
narrow vehicles such as motorbikes. In these cases, brake yourself as nec-
essary.
Vehicles with loads and special accessories
The load and special accessories of other vehicles that jut out over the side,
backwards or forward may be outside the range of the ACC.
Switch off the ACC when driving behind vehicles with loads or special acces-
sories, as well as when overtaking these vehicles. In these cases, brake
yourself as necessary. Other vehicles changing lanes
Vehicles changing lanes not far away from the vehicle can only be detected
when they fall within the range of the sensors. Consequently, the ACC will
take longer to react
⇒ Fig. 137 C. In these cases, brake yourself if necessary.
Stationary vehicles
During driving, the ACC does not detect stationary objects, such as the end
of a jam or damaged vehicles.
If a vehicle detected by ACC turns or moves over and there is another sta-
tionary vehicle in front of it, the ACC will not react ⇒ Fig. 137 D. In these ca-
ses, brake yourself if necessary.
Vehicles travelling in the opposite direction and vehicles changing lanes
The ACC does not react to vehicles approaching in the opposite direction or
vehicles changing lanes.
Metal objects
Metal objects, e.g. rails on the road or the panels used on work sites, may
confuse the radar sensor and cause wrong reactions in the ACC.
Factors that may affect the operation of the radar sensor
If the operation of the radar sensor were affected by heavy rain, water mist,
snow or mud, the ACC is switched off temporarily. The relevant message ap-
pears on the instrument panel display. If necessary, clean the radar sensor.
When the radar sensor works properly again, the ACC will be automatically
available again. The message on the instrument panel display will go off
and the ACC can be switched on again.
In the event of a heavy reverse reflection of the radar signal, for example, in
a closed parking, ACC operation may be affected.
Trailer towing
When driving with a trailer, the ACC controls less dynamically.

Fuses and bulbs
Fuses and bulbs Fuses
Introduction
Due to the constant update of vehicles, fuse assignments depending on
equipment and the use of the same fuse for various electrical components,
at the time of printing this manual it is not possible to provide an up-to-date
summary of the electrical components fuse positions. For detailed informa-
tion about the fuse positions, please consult a Technical Service.
In general, a fuse can be assigned to various electrical components. Like-
wise, an electrical component can be protected by several fuses.
Only replace fuses when the cause of the problem has been solved. If a
newly inserted fuse blows after a short time, you must have the electrical
system checked by a specialised workshop as soon as possible.
Additional information and warnings:
● Working in the engine compartment ⇒ page 251
WARNING
The high voltages in the electrical system can give serious electrical
shocks, causing burns and even death!
● Never touch the electrical wiring of the ignition system.
● Take care not to cause short circuits in the electrical system.
WARNING
Using unsuitable fuses, repairing fuses or bridging a current circuit with-
out fuses can cause a fire and serious injury.
● Never use a fuse with a higher value. Only replace fuses with a fuse of
the same amperage (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple or similar.
CAUTION
● To avoid damage to the vehicles electric system, before replacing a fuse
turn off the ignition, the lights and all electrical elements and remove the
keys from the ignition.
● If you replace a fuse with higher-rating fuse, you could cause damage to
another part of the electrical system.
● Protect the fuse boxes when open to avoid the entry of dust or humidity.
Dirt and humidity inside fuse boxes can cause damage to the electrical sys-
tem.
Note
● One single consumer could have more than one fuse.
● Several consumers could run over one single fuse.

Fuses and bulbs
Note
In the vehicle, there are more fuses than those indicated in this chapter.
These should only be changed by a specialised workshop.
Replacing a blown fuse
Fig. 179 Image of a
blown fuse
Preparation
● Switch off the ignition, lights and all electrical equipment.
● Open the corresponding fuse box ⇒ page 292.
Identifying a blown fuse
A fuse is blown if its metal strip is ruptured ⇒ Fig. 179.
Point a lamp at the fuse. This will make it easier to see if the fuse is blown. To replace a fuse
●
Remove the fuse.
● Replace the blown fuse by one with an identical amperage rating (same
colour and markings) and identical size ⇒
.
● Replace the cover again or close the fuse box lid.
CAUTION
If you replace a fuse with higher-rating fuse, you could cause damage to an-
other part of the electrical system.
Bulbs
Changing a bulb
Changing bulbs requires a certain degree of practical skill. If you choose to change engine compartment lamps yourself, remember
that it is a dangerous area ⇒
in Working on components in the engine
compartment on page 251.
Always use identical bulbs with the same designation. The name can be
found on the base of the bulb holder.
Depending on how equipped the vehicle is, there are different sets of head-
lights and tail lights:
● Halogen headlights
● Full-LED main headlights*
● Rear bulb light
● LED rear light*
