Central locking system Door locks – outsideThe conceptThe central locking system is ready for
operation as soon as you close the
driver's door. The system engages and
releases the locks on the
>doors
>luggage compartment lid
>fuel filler door.
The central locking system can be
operated
>from outside via the driver's door or
luggage compartment lock and with
the remote control
>from inside via the central locking
button.
The fuel filler door remains unlocked
when you activate the system from in-
side the vehicle.
The anti-theft system is automatically
armed whenever you activate the cen-
tral locking system from outside the ve-
hicle. The alarm system is also acti-
vated or deactivated.
In the event of an accident, the central
locking system unlocks automatically
(only those doors which were not
locked separately with the safety lock
buttons). Refer to page 36. In addition,
the hazard warning flashers and interior
lamps come on.
To engage and release locksOne turn of the key in the driver's door
lock unlocks the driver's door only.
Turning the key a second time unlocks
all of the remaining doors, the luggage
compartment lid and the fuel filler door.
When a door is opened, the inte-
rior lamps and the exterior door
handle illumination are switched on.
Switching off is automatic.< 380de015
Convenience operating modeYou can also use your remote control
transmitter to open and close the elec-
tric power windows and the sliding/tilt
sunroof.
>To open: With the door closed, turn
the key to the "Unlock" position and
hold it.
>To close: With the door closed, turn
the key to the "Lock" position and
hold it.
Watch the closing process care-
fully and be sure that no one is
trapped by the closing motion. The
movement stops when you release the
key.< Manual operation(in the event of an electrical failure)

left or right to unlock/lock the door.

Radio remote controlThe remote control makes opening and
locking the doors of your vehicle very
convenient. Furthermore, it provides
three additional functions which can
only be executed by means of the re-
mote control:
>Switching on the interior lamps and il-
luminating the exterior door handles.
With this function, you can also
"search for" your vehicle, when
parked in an underground garage, for
instance
>To open luggage compartment lid
The luggage compartment lid will
open slightly, regardless of whether
the lid was previously locked or un-
locked
>Panic Mode
In case of danger, you can trigger an
alarm.
The anti-theft system is also deacti-
vated/activated simultaneously with
the unlocking or locking of the vehicle,
and the alarm system is disarmed/
armed.
When the vehicle is unlocked, the inte-
rior lamps and the exterior door handle
illumination are switched on.
Master keysKeys with a transmitter for remote con-
trol are master keys. Refer to page 30.
Since children might be able to
lock the doors from the inside,
take the vehicle's keys with you so that
the vehicle can be opened again from
the outside at any time.<
Every transmission is indicated by a
light signal. If the signal no longer lights
up when a button is pressed and lock-
ing with the remote control no longer
functions:
Change the battery. Refer to page 168.380us644
Unlocking and convenience

Door locks – insideUse this button to operate the central
locking system when the front doors are
closed. With this button, only the doors
and luggage compartment lid are un-
locked or locked. The anti-theft system
is not activated.
The fuel filler door also remains un-
locked to allow refueling.
If only the driver's door was un-
locked from the outside and you
press the button
>all other doors, the luggage compart-
ment lid and the fuel filler door will be
unlocked if the driver's door is open
>the driver's door will be locked again
if it is closed.< 380de016
To unlock and open the doors>Either unlock the doors together with
the button for the central locking sys-
tem and then pull each of the release
handles above the armrests or
>pull the release handle for each door
twice: The first pull unlocks the door,
and the second one opens it.
To engage locks>Use the central locking system button
to locks all doors at once, or
>press down the individual door lock
buttons. As an added design feature
to prevent the driver from being inad-
vertently locked out of the vehicle,
the driver's door lock button will not
engage as long as the door is open.
When the vehicle is moving, do
not lock the doors with safety lock
buttons since the doors would not then
open automatically in the event of an
accident.
Children might be able to lock the doors
from the inside. For this reason, take
the vehicle's keys with you so that the
vehicle can be opened again from the
outside at any time.<
When the low beams are switched
on, the interior door handles are
lighted. The brightness is controlled by
the instrument panel lighting. Refer to

prox. +37.57 (+36), a warning signal
sounds and the display flashes briefly.
The warning is repeated whenever the
temperature goes to at least +437
(+66), and then drops to +37.57
(+36) again.
The ice warning does not alter the
fact that surface ice can form at
temperatures above +37.57 (+36), on
bridges or shaded road surfaces, for in-
stance.<
Never allow the engine to operate with
the needle in the red overspeed zone of
the gauge.
To protect the engine, the engine-man-
agement system automatically inter-
rupts the fuel supply in this range; the
resulting effect resembles that associ-
ated with a sudden loss of power.380us004

Energy control Fuel gaugeIndicates current fuel consumption in
mpg (in liters per 100 km on Canadian
vehicles). This instrument clearly
shows whether your current driving
style is conducive to economy and min-
