Operation
●
Never clo se the ti
lting sunroof without first
checking that there are no obstructions. Risk
of serious injury to you or others. Make sure
that no one is in the path of the tilting sun-
roof.
● Always take the vehicle key with you when
you leav
e the vehicle.
● Never leave children or disabled persons in
the vehicl
e, particularly if they have access to
the keys. Unsupervised use of a key could
mean that the engine is started or that elec-
trical equipment is used (e.g. electric tilting
sunroof) with a risk of accident. The doors
can be locked using the remote control key.
This could become an obstacle for assistance
in an emergency situation.
● The tilting sunroof continues to function
until one of
the front doors is opened and the
key removed from the ignition.
● Ensure that no object and/or end is be-
tween the glas
s and the sunroof when the
one-touch opening/closing function is reset. Convenience closing*
Using the door lock
– Hold the key in the door lock of the driver
door in the loc k
in g po

sition until the tilting
sunroof is closed.
– Release the key to interrupt this function. Using the remote control
– Push the lock button on the remote control
for appro

ximately 3 seconds. The tilting
sunroof closes.
– Press the unlock button to interrupt the
function.

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-
cre a

ses the risk of serious accidents.
● Always ensure that all windows are free of
ice and snow
, and that they are not fogged, so as to maintain good visibility of everything
outside.
●
The m ax

imum heat output required to de-
frost
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
system, fr
esh 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 c
ooling 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 required. WARNING
Stuffy or used air will increase fatigue and re-
duce driver c onc

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

uspect 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
pec

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

ature 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
windsc
reen 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 interior and i
s 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 windo
ws and the sliding/tilting
sunroof* 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, as
smoke drawn into the air condition-
ing system leaves residue on the evaporator,
producing a permanent unpleasant odour. 140

Air conditioning
●
At low out s
ide 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 e

ast 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 is u

nder extreme strain,
switch off the compressor for a moment. Economic use of the air conditioning
When the air conditioning is switched on, the
compre
s

sor 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 ehic

le 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 sw
itched on if the windows or
the sunroof* are open.

Introduction The power steering is not hydraulic but elec-
tromech
anic

al. 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 more s tr

ength to turn the wheel.
This has a considerable effect on vehicle
safety.
● The power steering only works when the
engine is ru
nning.
● Never allow the vehicle to move when the
engine is sw
itched off.
● Never remove the key from the ignition
while the v
ehicle is moving. The steering lock could be engaged and vehicle steering would
not work.
Note
The ignition of the vehicle being towed must
be sw itched on t

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

es are ignored when they light up, the
vehicle may stall in traffic and cause acci-
dents and severe injuries.
● Never ignore the warning lamps or messag-
es.
● Stop the v

ehicle at the next opportunity
and in a safe pl
ace. Note
Failure to heed the control lamps and corre-
sponding t e

xt messages when they light up
may result in damage to the vehicle. Information relating to different vehi-
cle pr
oc

esses. In order to make the vehicle more difficult to
ste
al,

you should always lock the steering be-
fore leaving the vehicle.
Mechanical steering lock
The steering column is locked when the key
is removed from the ignition lock and the ve-
hicle is stationary.
Activating the steering lock
● Park the vehicle ›››

p
age 152.
● Remove the ignition key.
● Turn the steering wheel slightly until the
steering loc
k has engaged.
Deactivating the steering lock
● Turn the steering wheel slightly to release
the lock.
● Insert

ectromechanical steering
In vehicl
es 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.
You should take into account that you will
need considerably more power than normal
to steer the vehicle if the power steering is
not working correctly or at all.
Power-assisted steering
Power-assisted steering helps the driver in
critical situations. In counter-steering, it as-
sists by applying additional torque ››› .
WARNING
Power-assisted steering, together with the
ESC, helps the driv

er to control vehicle steer-
ing in critical situations. However, the driver
is ultimately responsible for steering the ve-
hicle at all times. Power-assisted steering
does not remove this responsibility. 149

After starting a very hot engine, you may
need to slightly press down the accelerator.
When starting a cold engine, it may be a little
noisy for the first few seconds until oil pres-
sure has built up in the hydraulic valve com-
pensators. This is quite normal, and no cause
for concern.
If the engine does not start immediately,
switch the starter off after 10 seconds and try
again after half a minute. If the engine still
does not start, the fuel pump fuse should be
checked ›››
page 81, Fuses. WARNING
● Never st ar

t or run the engine in unventila-
ted or closed rooms. The exhaust gases con-
tain carbon monoxide, an odourless and col-
ourless poisonous gas. Risk of fatal acci-
dents. Carbon monoxide can cause loss of
consciousness and result in death.
● Never leave the vehicle unattended if the

Driving
of your brake pads checked by technical serv-
ic e
s mor
e 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
brake sy s

tem increase the risk of accidents.
● New brake pads must be run in and do not
have the corr
ect 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 ro
ads which have been salted,
braking power may be lower than normal.
● On steep slopes, if brakes are excessively
used, they wi
ll 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). Thus, make use of engine braking and
relieve the brakes.
● Never let the brakes “drag” by applying
light pres
sure. Continuous braking will cause the brakes to overheat and the braking dis-
tance w
i

ll increase. Apply and then release
the brakes alternately.
● Never let the vehicle run with the engine
switched off
. The braking distance is in-
creased considerably when the brake servo is
not active.
● If the brake fluid loses its viscosity and is
subject
ed 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
could r
estrict the airflow to the brakes and
cause them to overheat. Before purchasing
accessories please observe the relevant in-
structions ››› page 190, Modifications.
● If a brake system circuit fails, the braking
distanc
e 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
sk

idding 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 156.
For example:
● When driving with snow chains.
● When driving in deep snow or on loose sur-
face s.
● When the

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

es 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 f ollowing func-
tions:
● It flashes whilst driving when the ASR/ESC
is activat
ed.
● It will light up if there is a fault in the ESC.
● As the ESC operates in conjunction with the
ABS, the ESC light w
ill 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 on
press
ing the switch  or if we select ESC
Sport mode, only by means of Easy Connect. WARNING
● Do not for g

et 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 ro
ads and the traffic situa-
tion. The greater safety provided by the ESC
should not encourage you to run any risks. » 155

Operation
CAUTION
● To ens ur
e 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
exampl
e, 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 s

pinning when the vehicle is
accelerating. This system always includes
ABS.
Description and operation of the traction
control system during acceleration (ASR)
On front-wheel drive vehicles, the ASR sys-
tem intervenes, reducing engine power and
preventing the driven wheels from slipping
during acceleration. The system works in the
entire speed range in conjunction with ABS.
If a failure occurs in the ABS, the ASR will al-
so stop working.
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 s

tarted. If necessary, it could be
connected or disconnected by means of the
Easy Connect system.
When the ASR is off, the warning lamp lights
up . The ASR should normally be left on.
Only in exceptional circumstances, when
wheel spin is required, can they be turned off
using the ESC button, for example:
● With compact temporary spare wheel.
● When using the snow chains.
● When driving in deep snow or on soft ter-
rain.
● When the vehic

le is bogged-down, to free it
“by roc
king it.”
The ASR should be switched on again as
soon as possible.
Control lamp
There are two control lamps for the traction
control system:  and . Both control lamps
light up together when the ignition is switch-
ed on and should turn off after approximately
2 seconds. This is the time taken for the func-
tion check.
The  lamp has the following function:
● It flashes when the ASR is working if the ve-
hicle is
moving. If the system is deactivated or if it has any
fault, the warnin

g lamp will remain lit. The
warning lamp will also light up if a fault
should occur in the ABS because the ASR op-
erates in conjunction with the ABS. For fur-
ther information, see ››› page 156.
The  lamp provides information about the
disconnection status of the system:
● It stays lit when the ASR is disconnected
via Ea
sy Connect.
By means of Easy Connect, the ASR function
is reactivated and the warning lamp switched
off. WARNING
● Remember that 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 ro
ads and the traffic situa-
tion. The greater safety provided by the ASR
should not encourage you to run any risks. CAUTION
● To ens ur

e 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. 156

Driving
How the ABS works
If one of
the wheel s
turns too slowly in rela-
tion to the vehicle's speed, and is close to
locking, the system will reduce the braking
pressure to this wheel. The driver is made
aware of this control process by a pulsating
of the brake pedal and audible noise. This is
a deliberate warning to the driver that one or
more of the wheels 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 seconds.
● The control lamp lights up when the vehicle
is mov
ing.
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
possible.
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 ak

e 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 tyr
es fitted ››› page 213.
● If the running gear or brake system is modi-
fied, the effectivenes
s of the ABS could be se-
verely limited. WARNING
● Befor e openin

g the bonnet, read and ob-
serve the warnings ››› page 201, Working in
the engine compartment.
● If the brake system warning lamp  should
light up t
ogether with the ABS warning lamp
, stop the vehicle immediately and check
the brake fluid level in the reservoir
››› page 209, 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 sys
tem 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)*

mec h

anism 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 »
