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

hold button 1. The electric power win-
dows and the sliding/tilt sunroof are
opened.
If you desire, you can have this

Changing tires
Safety measures in the event of a
flat tire or wheel change:
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat, sur-
face.
Switch on the hazard flashers.
Turn the steering wheel to the straight-
ahead position, remove the key and en-
gage the steering lock. Make sure that
the selector lever is in Park, and engage
the parking brake.
All passengers should be outside the
car and well away from your immediate
working area (for instance, behind a
guardrail).
If a warning triangle or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle.
Comply with all safety guidelines and
regulations.
Change the wheel only on a level, firm
surface which is not slippery. Avoid
jacking the car on a soft or slippery sup-
port surface (snow, ice, loose gravel,
etc.), since it could slide sideways.
Position the jack on a firm support sur-
face.
Do not place wooden blocks or similar
objects under the jack. If this is done,
the jack might not be able to reach its
full support capacity because of the
limited height. Do not lie under the vehi-
cle or start the engine when the vehicle
is supported by the jack - risk of fatal
injury.<
What you will needIn order to avoid rattling noises later,
note the position of the tools when you
remove them and return them to their
original position when you are through
using them.
>Car jack
Fold the right-hand trim panel of the
luggage compartment down using
the handle at the top.
Loosen the wing nut (arrow 1).
When you have completed work,
screw the jack all the way back down.
Fold the handle back and insert it in
its holder.
>Wedge (wheel chock)
Next to the battery, under the jack.
Remove the jack and loosen the wing
nut (arrow 2).380de639
