The air conditioner operates most effectively
with the windows and the panoramic 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 quick-
ly by opening the windows and the panoram-
ic sliding sunroof briefly.

lowing:
● The engine is not running.
● The fan is switched off.
● The air conditioner fuse has blown.
● The outside temperature is lower than ap-

coolant temperature is too high.
● Another fault in the vehicle. Have the air
conditioner chec
ked by a specialised work-
shop. Special Characteristics
If the humidity and t
emperature outside the

Auxiliary heater (additional
he at
er)*
Intr
oduction The auxiliary heater runs on fuel from the ve-
hicl
e's
tank and can be used while you are
driving and when the vehicle is stationary.
The auxiliary heater can be switched on using
the fast heating button of the air condition-
ing controls, with the remote control or by
previously programming a departure time in
the auxiliary heater menu of the infotainment
system.
In winter, with the auxiliary heater switched
on, you can defog the windscreen and leave
it free of ice and snow (if it is a thin layer) be-
fore you start driving.
If the outside temperature is very high, the
vehicle interior can be ventilated with the en-
gine off using the auxiliary heater. WARNING
Swallowing a battery with a 20 mm diameter
or any other b
utton battery can cause serious
and even fatal injuries within a very short
time.
● Always keep the remote control, keyrings
with batt
eries, the spare batteries, button
batteries and all other batteries over 20 mm
out of reach of children. ●
If y
ou suspect that someone may have
swallowed a battery, seek immediate medical
attention. WARNING
The auxiliary heater exhaust fumes contain
c arbon mono x
ide, an odourless and colour-
less toxic gas. Carbon monoxide can cause
people to lose consciousness. It can also
cause death.
● Never switch on the auxiliary heater or
leav
e it running in enclosed spaces or areas
with no ventilation.
● Never programme the auxiliary heater so
that it
switches itself on and is running in an
enclosed space or an area with no ventila-
tion. WARNING
The components of the auxiliary heater are
extr emely
hot and could cause a fire.
● Always park your vehicle so that no part of
the exhau
st system can come in contact with
easily flammable materials that might be be-
low the vehicle, such as dried grass. CAUTION
Never place food, medicines or other temper-
atur e-
sensitive objects close to the air vents.
Food, medicines and other objects sensitive
to heat or cold may be damaged or made un- suitable for use by the air coming from the

Operation
● Sec ur
e the
vehicle as usual by applying the
electronic parking brake firmly and putting it
in 1st gear. WARNING
● Tak e me
asures to reduce the risk of injury
when you leave your vehicle unattended.
● Never park where the hot exhaust system
coul
d ignite inflammable materials, such as
dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in
the vehic
le when it is locked. They would be
unable to open the vehicle from the inside,
and could become trapped in the vehicle in
an emergency. In the event of an emergency,
locked doors will delay assistance to vehicle
occupants.
● Never leave children alone in the vehicle.
They cou
ld set the vehicle in motion, for ex-
ample, by releasing the electronic parking
brake or the gearshift lever, which would
cause the vehicle to move, but uncontrolla-
bly.
● Depending on weather conditions, it may
become extr
emely hot or cold inside the vehi-
cle. This can be fatal. Information on the brakes
New brake pads
F
or the fir s
t 400 km (250 miles), new brake
pads have not yet reached their maximum
braking capacity, and need to be “run in” first. However, you can compensate for the
slightly r
educed braking effect by applying
more pressure on the brake pedal. Avoid
overloading the brakes while running them
in.
Wear
The rate of wear on the brake pads depends
a great deal on how you drive and the condi-
tions in which the vehicle is operated. This is
a particular problem in urban traffic and
short stretches, or with very sporty driving.
Depending on the speed, the braking force
and the environmental conditions (for exam-
ple, the temperature, air humidity, etc.)
noises may be produced on braking.
Wet roads or road salt
In certain situations (for example, on driving
through flooded areas, in severe downpours
or after washing the vehicle) the braking ac-
tion could be delayed if the discs and pads
are damp, or frozen in winter. In this case the
brakes should be “dried” by pressing the
brake pedal several times.
At high speed and with the windscreen wip-
ers activated, the brake pads will briefly
touch the brake discs. This takes place, al-
though unnoticeable to the driver, at regular
intervals to improve the response time of the
brakes when they are wet. The effectiveness of the brakes can also be
temporari
ly reduced if the vehicle is driven
for some distance without using the brakes
when there is a lot of salt on the road in win-
ter. The layer of salt that accumulates on the
discs and pads can be removed by gently ap-
plying the brakes a few times.
Corrosion
There may be a tendency for corrosion to
form on the discs and dirt to build up on the
brake pads if the vehicle is used infrequently
or the brakes are not used very often.
If the brakes are not used frequently, or if
rust has formed on the disks, it is advisable
to clean off the pads and disks by braking
firmly a few times at a moderately high speed
››› .
F au
lt
in the brake system
If the brake pedal travel should ever increase
suddenly, this may mean that one of the two
brake circuits has failed. Drive immediately
to the nearest specialised workshop and
have the fault repaired. Drive there slowly
and remember that you will have to apply
more pressure on the brake pedal and allow
for longer stopping distances.

Operation
the other driven wheel. This function is active
up t o ap
pr
oximately 100 km/h (62 mph).
To prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automati-
cally if subjected to excessive loads. The ve-
hicle can still be driven. The EDL will switch
on again automatically when the brake has
cooled down.
Tractor-trailer sway mitigation*
If the vehicle is pulling a trailer, it will control
the following: Tractor-trailers tend to sway.
When the swaying of the trailer is felt by the
vehicle and detected by the ESC, it will auto-
matically brake the towing vehicle within the
limits of the system and mitigate the sway.
Tractor-trailer sway mitigation is not available
in all countries.
Electronic torque management (XDS)
When taking a curve, the driveshaft differen-
tial mechanism allows the outer wheel to turn
at a higher speed than the inner wheel. In
this way, the wheel that is turning faster (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving a lower drive torque than it could
transmit. This causes an overall loss of lateral
grip on the front axle, resulting in understeer
or “lengthening” of the trajectory. The XDS system can detect and correct this
effect
via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise.
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected, or the ESC in
Sport mode or disconnected.
Multi-collision brake
In an accident, the multi-collision brake can
help the driver by braking to avoid the risk of
skidding during the accident, which could
lead to further collisions.
The multi-collision brake works for front, side
or rear accidents, when the airbag control
unit records its activation level and the acci-
dent takes place at a speed of over 10 km/h
(6 mph). The ESC automatically brakes the
vehicle, as long as the accident has not dam-
aged the ESC, the brake hydraulics or the on-
board network
The following actions control automatic brak-
ing during the accident:
● When the driver presses the accelerator,
the automatic
braking does not take place.
● When the braking pressure through press-
ing the brak
e pedal is greater than the sys- tem’s braking pressure the vehicle will brake
automatic
ally.
● Multi-collision braking will not be available
if ESC
is malfunctioning. WARNING
● The ESC, ABS, ASR, ED S
and the electronic
torque control system cannot exceed the lim-
its imposed by the laws of physics. Always
bear this in mind, especially on wet or slip-
pery roads. If you notice the systems cutting
in, you should reduce your speed immediate-
ly to suit the road and traffic conditions. Do
not be encouraged to take risks by the pres-
ence of more safety systems. If you do, an ac-
cident may occur.
● Please remember that the accident risk al-
way
s increases if you drive fast, especially in
corners or on a slippery road, or if you follow
too close behind the vehicle in front of you.
The ESC, ABS, brake assist, EDS and the elec-
tronic torque control system cannot prevent
accidents: risk of accidents!
● Accelerate with caution on slippery surfa-
ces
(for example, icy or snow-covered). De-
spite the control systems, the driven wheels
could spin, affecting the stability of the vehi-
cle: risk of accident! Note
● The ABS and ASR w i
ll only operate correctly
if the four wheels have identical tyres. Any
differences in the rolling radius of the tyres 190

The engine stops when the selector lever is in
the positions P, D, N and S, in addition to
when in manual mode. With the selector lev-
er in position P, the engine will also remain
switched off when you take your foot off the
brake pedal. In order to start the engine up
again the accelerator must be pressed, or an-
other gear engaged or the brake released.
If the selector lever is placed in position R
during the stopping phase, the engine will
start up again.
Change from position D to P to prevent the
engine from accidentally starting when
changing and passing by position R.
Additional information about vehicles with
Adaptive Cruise Control (ACC)
In vehicles with ACC function, the engine will
start up again in certain operating conditions
if the radar sensor detects that the vehicle
ahead drives off again. Note
● In v ehic
les with an automatic gearbox, you
can control whether the engine should switch
off or not by reducing or increasing the brake
force applied. While the vehicle remains stop-
ped, the engine will not stop if the brake ped-
al is slightly pressed, in traffic jams with fre-
quent stopping and starting for example. As soon as strong pressure is applied to the
brak
e ped
al, the engine will stop.
● In vehicles with manual gearbox, during
the stop
ping phases the brake pedal must re-
main depressed to prevent the vehicle from
moving.
● If the engine “stalls” in vehicles with man-
ual g
earbox, it can be directly started up
again by immediately pressing the clutch
pedal. General notes
