There are red warning symbols (priority 1)
and yellow warning symbols (priority 2).
Warning messages, Priority 1 (red)
If one of these faults occurs, the warning
lamp will light up or flash and will be accom-
panied by three audible warnings. This is a
danger warning. Stop the vehicle and switch
off the engine. Check the fault and correct it.
Obtain professional assistance if necessary.
If several priority 1 faults are detected at the
same time, the symbols will be displayed one
after the other for about 2 seconds at a time
and will continue until the fault is corrected.
No menus will be shown in the display for the
duration of a priority 1 warning message.
Examples of priority 1 warning messages

Warning messages, Priority 2 (yellow)
If one of these faults occurs, the correspond-
ing warning lamp lights up and is accompa-
nied by an audible warning. Check the corre-
sponding function as soon as possible al-
though the vehicle may be used without risk.
If several priority 2 warning messages are de-
tected at the same time, the symbols are dis-
played one after the other for about 2 sec-

Pollution filter
The pollution filter (a combined particulate
filter and active carbon filter) serves as a bar-
rier against impurities in the outside air, in-
cluding dust and pollen.
For the climate control system to work with
maximum efficiency, the pollution filter must
be replaced at the specified intervals in the
Maintenance Programme.
If the filter loses efficiency prematurely due
to use in areas reaching very high pollution
levels, the pollen filter must be changed
more frequently than stated in the Service
Schedule. WARNING
Reduced visibility through the windows in-
cr e

ases the risk of serious accidents.
● Always ensure that all windows are free of
ice and sno
w, and that they are not fogged, so as to maintain good visibility of everything
outs
ide.
● The m

aximum heat output required to de-
fros
t windows as quickly as possible is only
available when the engine has reached its
normal running temperature. Only drive when
you have good visibility.
● Always ensure that you use the heating
syst
em, fresh air system, air conditioner and
the heated rear window to maintain good visi-
bility to the outside.
● Never leave the air recirculation on for a
long period of time. If
the cooling system is
switched off and air recirculation mode
switched on, the windows can mist over very
quickly, considerably limiting visibility.
● Switch air recirculation mode off when it is
not requir
ed. WARNING
Stuffy or used air will increase fatigue and re-
duce driv er c

oncentration possibly resulting
in a serious accident.
● Never leave the fresh air fan turned off or
use the air rec
irculation for long periods of
time; the air in the vehicle interior will not be
refreshed. CAUTION
● If y

ou suspect that the air conditioner is
damaged, switch it off with the A/C button to prevent further damage and have it checked
by
a s

pecialised workshop.
● Repairs to the air conditioner require spe-
cia
list knowledge and special tools. There-
fore, we recommend you to take the vehicle
to a specialised workshop. Note
● If the humidity and t

emperature outside the
vehicle are high, condensation can drip off
the evaporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak.
● Keep the air intake slots in front of the
winds
creen free of snow, ice and leaves to en-
sure heating and cooling are not impaired,
and to prevent the windows from misting
over.
● The air from the vents flows through the ve-
hicle int
erior and is extracted by slots in the
luggage compartment designed for this pur-
pose. Therefore, you should avoid obstruct-
ing these slots with any kind of object.
● The air conditioner operates most effective-
ly with the w
indows closed. However, if the
temperature inside the vehicle is excessive
because of the sun, the air inside can be
cooled faster by opening the windows for a
short time.
● Do not smoke while air recirculation mode
is on, a
s smoke drawn into the air condition-
ing system leaves residue on the evaporator,
producing a permanent unpleasant odour. 158

Air conditioning
●
At lo w out
side temperatures, the compres-
sor switches off automatically and cannot be
switched on even with the AUTO button.
● It is advisable to turn on the air condition-
ing at l

east once a month, to lubricate the
system gaskets and prevent leaks. If a de-
crease in the cooling capacity is detected, a
Technical Service should be consulted to
check the system.
● To ensure correct operation, the grilles on
both sides
of the screen must not be obstruc-
ted. ●
When the engine i s

under extreme strain,
switch off the compressor for a moment. Economic use of the air conditioning
When the air conditioning is switched on, the
compr
e

ssor consumes engine power and has
influence on fuel consumption. Consider the
following points in order to have the system
operating in the minimum possible time. ●
If the v

ehicle interior has overheated due to
an excessive solar radiation, it is best to
open the windows or doors to allow the hot
air to escape.
● While in motion, the air conditioning
should not
be switched on if the windows are
open.

Introduction The power steering is not hydraulic but elec-
tromec
h

anical. The advantage of this steer-
ing is that it foes not need flexible hydraulic
pipes, hydraulic oil, pump, filter or other
parts. The electromechanical system saves
fuel. Whereas a hydraulic system needs con-
tinuous oil pressure, electromechanical
steering only needs power when it is used.
In vehicles with electromechanical steering,
the assisted steering function automatically
adjusts according to vehicle speed, steering
wheel torque and wheel orientation. The
power steering only works when the engine
is running. WARNING
If the power steering does not work, you will
need much mor e s

trength to turn the wheel.
This has a considerable effect on vehicle
safety.
● The power steering only works when the
engine is
running.
● Never allow the vehicle to move when the
engine is
switched off.
● Never remove the key from the ignition
while the
vehicle is moving. The steering lock could be engaged and vehicle steering would
not w
ork. Note
The ignition of the vehicle being towed must
be sw itc

hed on to prevent the steering wheel
from locking and also to allow the use of the
turn signals, horn, windscreen wipers and
washers. Control lamp

a great extent on the conditions under which
the v
ehic
le is operated and the way the vehi-
cle is driven. If you often drive in town, drive
short distances or have a sporty driving style,
we recommend that you have the thickness
of your brake pads checked by technical serv-
ices more frequently than recommended in
the Maintenance Programme.
If you drive with wet brakes, for example, af-
ter crossing areas of water, on days of heavy
rainfall or even after washing the car, the ef-
fect of the brakes is reduced as the brake
discs are wet or even frozen (in winter): in
this case, the brakes should be “dried” by
pressing the brake pedal several times. WARNING
Longer braking distances and faults in the
brak e sy

stem increase the risk of accidents.
● New brake pads must be run in and do not
have the c
orrect friction during the first
200 km. This reduced braking capacity may
be compensated for by pressing on the brake
pedal a little harder, which also applies when
the brake pads have to be changed further
on.
● If brakes are wet or frozen, or if you are
driving on r
oads which have been salted,
braking power may be lower than normal.
● On steep slopes, if brakes are excessively
used, they w
ill overheat. Before driving down
a long steep slope, it is advisable to reduce
speed and change down into a lower gear or range (depending on the type of transmis-
sion).
Thu

s, make use of engine braking and
relieve the brakes.
● Never let the brakes “drag” by applying
light pre
ssure. Continuous braking will cause
the brakes to overheat and the braking dis-
tance will increase. Apply and then release
the brakes alternately.
● Never let the vehicle run with the engine
switc
hed off. The braking distance is in-
creased considerably when the brake servo is
not active.
● If the brake fluid loses its viscosity and is
subj
ected to heavy use, vapour bubbles can
form in the brake system. This reduces the ef-
ficiency of the brakes.
● Non-standard or damaged front spoilers
coul
d restrict the airflow to the brakes and
cause them to overheat. Before purchasing
accessories please observe the relevant in-
structions ››› page 255, Modifications.
● If a brake system circuit fails, the braking
dist
ance will be increased considerably. Con-
tact a specialised workshop immediately and
avoid unnecessary journeys. Control lamp

Braking and stability systems El ectr
onic
Stability Control (ESC)*This Electronic Stability System reduces the
risk
of

skidding and improves the vehicle's
stability and ability to hold the road.
The Electronic Stability Control (ESC) contains
the electronic differential lock (EDL) and the
traction control system (ASR). The ESC works
together with the ABS. Both control lamps
will light up if the ESC or ABS systems are
faulty.
The ESC system is started automatically
when the engine is started.
The ESC system is always active and cannot
be switched off. With the Easy Connect sys-
tem it is only possible to deactivate the ASR
or else select Sport mode.
The ASR can be deactivated when wheel spin
is desirable ›››
page 178.
For example:
● When driving with snow chains.
● When driving in deep snow or on loose sur-
fac e

s.
● When the vehicle is stuck, to rock it back-
ward
s and forwards.
Press the button to switch the ASR back on
when you no longer need wheel spin. Electronic Stability Control (ESC)*
The ESC r

educes the risk of skidding by brak-
ing the wheels individually.
The system uses the steering wheel angle
and road speed to calculate the changes of
direction desired by the driver, and constant-
ly compares them with the actual behaviour
of the vehicle. When irregularities occur, for
example, if the vehicle begins to skid, the
ESC brakes the appropriate wheel automati-
cally.
The forces acting on the braked wheel bring
the vehicle back to a stable condition. If the
vehicle tends to oversteer (the rear end
slides out), the system will act on the front
wheel on the outside of the turn.
Control lamp
There are two control lamps for the electronic
stability control. The lamp  provides infor-
mation concerning function and  disconnec-
tion status.
Both control lamps light up together when
the ignition is switched on and should turn
off after approximately 2 seconds. This is the
time taken for the function check.
This programme includes the ABS, EDL and
ASR. It also includes emergency braking as-
sistance (BAS). The control lamp
 has the following func-
tions:
● It flashes whilst driving when the ASR/ESC
is activ
ated.
● It will light up if there is a fault in the ESC.
● As the ESC operates in conjunction with the
ABS, the ESC light
will also come on if a fault
should occur in the ABS.
If the ESC control lamp  lights up and stays
on after the engine is started, this may mean
that the control system has temporarily
switched off the ESC. In this case the ESC can
be reactivated by switching the ignition off
and then on again. If the control lamp goes
out, this means the system is fully functional.
The  lamp provides information about the
disconnection status of the system:
● It stays lit when the ASR is disconnected or
if y
ou select ESC Sport mode, only by means
of Easy Connect. WARNING
● Do not f or

get that the electronic stability
control ESC cannot defy the laws of physics.
This should be kept in mind, particularly on
slippery and wet roads and when towing a
trailer.
● Always adapt your driving style to suit the
condition of the r
oads and the traffic situa-
tion. The greater safety provided by the ESC
should not encourage you to run any risks. » 177

Operation
CAUTION
● To en s
ure that the ESC works correctly, all
four wheels must be fitted with the same
tyres. Any differences in the rolling radius of
the tyres can cause the system to reduce en-
gine power when this is not desired.
● Any modifications made to the vehicle (for
examp
le, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS, EDL, ESC and ASR. Traction control system (ASR)
The traction control system prevents the driv-
en wheel
s
fr

om spinning when the vehicle is
accelerating.
Description and operation of the traction
control system during acceleration (ASR)
The ASR system intervenes by reducing en-
gine power and preventing the driven wheels
from slipping during acceleration.
TCS helps the car to start moving, accelerate
and climb a gradient in slippery conditions
where this may otherwise be difficult or even
impossible.
The ASR automatically switches on when the
engine is started. If necessary, it could be
switched on or off using the Easy Connect
system*. When the ASR is off, the warning lamp lights
up . The ASR shoul

d normally be left on.
Only in exceptional circumstances, when
wheel spin is required, it can be turned off
using the Easy Connect system menu, for ex-
ample:
● With compact temporary spare wheel.
● When using the snow chains.
● When driving in deep snow or on soft ter-
rain.
● When the v

ehicle is bogged-down, to free it
“by r
ocking it.”
The ASR should be switched on again as
soon as possible.
Control lamp
There are three control lamps for the traction
control system:  (for vehicles equipped
with M-ABS),  (for vehicles equipped with
ESC) and . Both control lamps light up to-
gether when the ignition is switched on and
should turn off after approximately 2 sec-
onds, which is the time taken for the function
check.
The  or  lamp has the following function:
● It flashes when the ASR is working if the ve-
hicle i
s moving.
If the system is deactivated or if it has any
fault, the warning lamp will remain lit. The warning lamp will also light up if a fault
should oc

cur in the ABS because the ASR op-
erates in conjunction with the ABS. For fur-
ther information, see ››› page 178.
The  lamp provides information about the
disconnection status of the system:*
● It stays lit when the ASR is disconnected
via E
asy Connect.
By means of Easy Connect, the ASR function
is reactivated and the warning lamp switched
off. WARNING
● Remember th at

not even the ASR can defy
the laws of physics. This should be kept in
mind, particularly on slippery and wet roads
and when towing a trailer.
● Always adapt your driving style to suit the
condition of the r
oads and the traffic situa-
tion. The greater safety provided by the ASR
should not encourage you to run any risks. CAUTION
● To en s

ure that the ASR works correctly,
identical tyres should be fitted on all four
wheels. Any differences in the rolling radius
of the tyres can cause the system to reduce
engine power when this is not desired.

Driving
a deliberate warning to the driver that one or
mor e of
the wheel
s is tending to lock and the
ABS control function has intervened. In this
situation it is important to keep the brake
pedal fully depressed so the ABS can regu-
late the brake application. Do not “pump”.
If you brake hard on a slippery road surface,
the best possible control is retained as the
wheels do not lock.
However, ABS will not necessarily guarantee
shorter braking distances in all conditions.
Braking distance could even be further if you
brake on gravel or on fresh snow on a slip-
pery surface.
Control lamp
The control lamp  lights up for a few sec-
onds when the ignition is switched on. It
goes out again after the system has run
through an automatic test sequence.
There is a fault in the ABS if:
● The control lamp  does not
light up when
the ignition is switched on.
● The control lamp does not go out again af-
ter a few sec
onds.
● The control lamp lights up when the vehicle
is mo
ving.
The vehicle can still be braked in the normal
way, without the ABS function. Take the vehi- cle to a specialised workshop as soon as
poss

ible.
If there is a fault in the ABS, the ESC* and the
tyre pressure control lamp will also light up.
Brake system fault
If the ABS warning lamp  lights up together
with the brake warning lamp , there is a
fault in the ABS function and in the brake
system ››› .
WARNING
● The anti-lock br

ake system cannot defy the
laws of physics. Slippery and wet roads are
dangerous even with ABS! If you notice that
the ABS is working (to counteract locked
wheels under braking), you should reduce
speed immediately to suit the road and traffic
conditions. Do not let the extra safety fea-
tures tempt you into taking any risks when
driving.
● The effectiveness of ABS is also determined
by the ty
res fitted ››› page 278.
● If the running gear or brake system is modi-
fied, the effectivene
ss of the ABS could be se-
verely limited. WARNING
● Bef or

e opening the bonnet, read and ob-
serve the warnings ››› page 267, Working in

If the br ak

e system warning lamp  should

the brake fluid level in the reservoir
››› page 275, Brake fluid. If the brake fluid
level has dropped below the “MIN” mark you
must not drive on. Risk of accident. Obtain
technical assistance.
● If the brake fluid level is correct, the fault in
the brake sy
stem may have been caused by a
failure of the ABS system. This could cause
the rear wheels to lock quickly when you
brake. This could cause the rear to break
away. Risk of skidding. Stop the vehicle and
seek technical assistance. Electronic differential lock (XDS)*
When taking a curve, the driveshaft differen-
ti
al
mec

hanism 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
