Operation
Once the doors have been locked, they can-
not be opened ag
ain immedi
ately. This will
enable you to check that the doors are prop-
erly closed.
If you wish, when unlocking, you can unlock
only the driver’s door, the side being un-
locked, or the entire vehicle. The necessary
adjustments can be performed in vehicles
with a driver information system
››› page 34.
General information
If a valid key is located in the proximity of the
car ››› Fig. 142, the Keyless Access locking
and starting system gives the key entry as
soon as one of the sensor surfaces on the
driver door handle is touched. The following
features are then available without having to
use the vehicle key actively:
● Keyless-Entry: unloc
king the vehicle using
the handle of the front driver’s door or the
softtouch/handle on the rear lid.
● Keyless-Exit: lockin
g the vehicle using the
sensor on the driver door handle.
● Press & Drive: keyle
ss starting of the en-
gine with the starter button ››› page 176.
The central locking and locking systems oper-
ate in the same way as a normal locking and
unlocking system. Only the controls change. Unlocking the vehicle is confirmed with a
double fl
ash of the indicator lights; locking
by a single flash.
If the vehicle is locked and then all doors and
the rear lid are closed leaving the last key
used inside the vehicle and none outside,
the vehicle will not lock immediately. All the
vehicle's indicator lights will flash four times.
The vehicle will lock after a few seconds if
you do not open any door or the rear lid.
The vehicle will lock again after a few sec-
onds if you unlock the vehicle but fail to open
any door or boot hatch.
Unlocking and opening the doors (Keyless-
Entry)
● Grip the driver door lever. In doing this, the
sensor sur

s touched and the vehicle unlocks.
● Open the door.
On vehic
les with selective opening or info-
tainment system configuration, pulling the
door handle twice will unlock all doors.

Unlocking and locking the boot hatch
When the vehicle is locked, the rear lid auto-
matically unlocks on opening if there is a val-
id vehicle key in the proximity ››› Fig. 142.
Open or close the rear lid normally.
After closing, the hatch locks automatically. If
the complete vehicle is unlocked, the rear lid
will not lock automatically after closing it.

the door i s
opened u
ntil the key is inserted
into the contact should not exceed 15 sec-
onds, otherwise the alarm will be triggered.
– Press the button on the remote c
ontrol
twice. The volumetric sensor and tilt sen-
sors will be deactivated. The alarm system
remains activated.
The vehicle interior monitoring and the anti-
tow system are automatically switched on
again next time the vehicle is locked.
The vehicle interior monitoring and anti-tow
sensor (tilt sensor) are automatically switch-
ed on when the anti-theft alarm is switched
on. In order to activate it, all the doors and
the rear lid must be closed.
If you wish to switch off the vehicle interior
monitoring and the anti-tow system, it must
be done each time that the vehicle is locked;
if not, they will be automatically switched on.
The vehicle interior monitoring and the anti-
tow system should be switched off if animals
are left inside the locked vehicle (otherwise,
their movements will trigger the alarm) or
when, for example, the vehicle is transported
or has to be towed with only one axle on the
ground. False alarms
Interior monitorin
g will only operate correctly
if the vehicle is completely closed. Please ob-
serve related legal requirements.
The following cases may cause a false alarm:
● Open windows (partially or fully),
● Movement of objects inside the vehicle,
such a
s loose papers, items hanging from
the rear vision mirror (air fresheners), etc. Note
● If the v
ehicle is relocked and the alarm is
activated without the volumetric sensor func-
tion, relocking will activate the alarm with all
its functions, except the volumetric sensor.
This function is reactivated when the alarm is
switched on again, unless it is deliberately
switched off.
● If the alarm has been triggered by the volu-
metric sensor
, this will be indicated by a
flashing of the warning lamp on the driver
door when the vehicle is opened. The flash is
different to the flash indicating the alarm is
activated.
● The vibration of a mobile phone left inside
the vehic
le may cause the vehicle interior
monitoring alarm to trigger, as both sensors
react to movements and shakes inside the ve-
hicle.
● If on activating the alarm, any door or the
rear lid i
s open, only the alarm will be activa-
ted. The vehicle interior monitoring and the anti-tow system will only be activated once
al
l
the doors are closed (including the rear
lid). Deactivating the vehicle interior moni-
torin
g and anti-t
ow system* When the vehicle is locked, the alarm will be
trigg
er
ed if movements are detected in the
interior (e.g. by animals) or if the vehicle's in-
clination is changed (e.g. during transport).
You can prevent the alarm from being trig-
gered accidentally by switching off the vehi-
cle interior monitoring and/or tow-away pro-
tection.
– To switch off the interior monitoring and
to w-

ch on the wipers.
● If necessary, switch on the wipers manually
when water on the w
indscreen obstructs visi-
bility. CAUTION
In icy conditions, always check that the wind-
sc r
een wipers and the window wiper are not
frozen. If you switch on the windscreen wip-
ers when the wiper blades are frozen to the
windscreen, you could damage both the wip-
er blades and the wiper motor. Note
● The wiper s
and washers will work only
when the ignition is switched on.
● The heat output of the heated jets* is con-
trol
led automatically when the ignition is
switched on, depending upon the outside
temperature.
● In certain versions of vehicles with alarms,
the winds
creen wiper will only work in inter-
val/rain sensor mode when the ignition is on
and the bonnet closed. ●
When the inter v
al wipe function is on, the
intervals are directly proportional to the
speed. This way, the higher the vehicle speed
the shorter the intervals.
● If you stop the vehicle with the windscreen
wiper in pos
ition 1 or 2, it will automatically
change to a lower position speed. The set
speed will be resumed when the vehicle pulls
away.
● The windscreen will be wiped again after
appro
ximately five seconds once the “auto-
matic wash/wipe system” has been activa-
ted, provided the vehicle is moving (drip func-
tion). If you activate the wipers less than 3
seconds after the drip function, a new wash
sequence will begin without performing the
last wipe. For the “drip” function to work
again, you have to turn the ignition off and
then on again.
● Do not put stickers on the windscreen in
front of
the rain sensor*. This may cause sen-
sor disruption or faults.
● Depending on the version of the model,
when you en
gage reverse gear and with the
headlight wiper activated, this can start a
wipe. Rear view mirrors
Int erior mirr or It is dangerous to drive if you cannot see

le
arly through the rear window. Interior mirror with automatic anti-dazzle
function*
The anti-d
azzle function is activated every
time the ignition is switched on.
When the anti-dazzle function is enabled, the
interior rear vision mirror will darken auto-
matically according to the amount of light it
receives. The anti-dazzle function is cancel-
led if reverse gear is engaged. Note
● The autom atic
anti-dazzle function will only
work properly if the sun blind* for the rear
window is retracted and there are no other
objects preventing light from reaching the in-
terior rear vision mirror.
● If you have to stick any type of sticker on
the winds
creen, do not do so in front of the

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. 164

Braking and parking Brakin
g capacity and braking distance The efficiency of the brakes depends directly
on the br
ak
e p
ad wear. This wear depends to a great extent on the conditions under which
the vehic
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 (124 miles). This reduced braking ca-
pacity 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 259, Technical modifica-
tions.
● 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
