tionally convenient method for
unlocking and locking your vehicle.

Since children might be able to
lock the doors from the inside,
always take the vehicle keys with you
so that the vehicle can be opened again
from the outside at any time.<
If it is no longer possible to lock
the vehicle via the remote control,
the battery is discharged. Use this key
while driving for an extended period in
order to recharge the battery.

Alarm system
*
The conceptThe vehicle alarm system responds:
>When a door, the hood or the
luggage compartment lid is opened
>To movement inside the vehicle (inte-
rior motion sensor)
>To variations in the vehicle's tilt angle
such as those occurring during
attempts to steal the wheels or tow
the vehicle
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>The acoustic alarm sounds for
30 seconds
>The hazard warning flashers are acti-
vated for approx. five minutes
>The high beams flash on and off in
rhythm with the hazard warning
flashers.
To arm and disarm the alarm
systemWhen the vehicle is locked or unlocked
via the driver's door lock or with the
remote control, the alarm system is also
simultaneously armed or disarmed.
You can have different acknowl-
edgment signals set to confirm
arming and disarming.<
You can open the luggage compart-
ment lid even when the system is
armed by pressing the button on the
remote control, refer to page 30. When
it is closed, the lid is once again
secured.
Indicator lamp displays>The indicator lamp below the interior
rearview mirror flashes continuously:

>The indicator lamp flashes during
arming: the door(s), the hood or
luggage compartment lid are not
completely closed. Even if you do not
close the alerted area(s), the
remaining areas are secured, and the
indicator lamp will flash continuously
after 10 seconds. However, the inte-
rior motion sensor is not activated

Transporting children safelyCommercially available child seats
complying with the legal standard are
designed to be secured with a seat belt
or with the seat belt portion of a combi-
nation lap/shoulder belt.
Improperly or inadequately installed
restraint systems can increase the risk
of injury to children. Always read and
follow the instructions that come with
the system.
If you use a child-restraint system with
a tether strap, three additional tether
anchorage points (refer to the arrows in
the illustration) have been provided.
Depending on the location selected
for seating in the rear passenger area,
attach the tether strap to the
corresponding anchorage point to
secure the child-restraint system.
Remove the center cover first.
If the selected seating position is fitted
with a headrest lift the headrest and
pass the tether strap between the
headrest and the backrest.
Adjust the tether strap according to the
child-restraint manufacturer's
instructions.
Before installing any child-
restraint device or child seat,
please read the following:
Never install a rear-facing child-
restraint system in the front passenger
seat of this vehicle.
Your vehicle is equipped with an airbag
supplemental restraint system for the
front passenger. Because the backrest
on any rear-facing child-restraint
system (of the kind designed for infants
under 1 year and 20 lbs/9 kg) would be
within the airbag's deployment range,
you should never mount such a device
in the front passenger seat, as the
impact of the airbag against the child
restraint's backrest could lead to
serious or fatal injuries.
If it is necessary for a child (not an
infant) to ride in the front seat, certain
precautions should be taken. First,
move the passenger seat as a far away
from the dashboard as possible. This
important precaution is intended to
maximize the distance between the
airbag and the child. Older children
should be tightly secured with the
safety belt. Younger children should be
secured in an appropriate forward-
facing child-restraint system that has
first been properly installed with a
safety belt. Never install a rear-facing
child-restraint system in the front
passenger seat.
We strongly urge you to carefully read
and observe the instructions for instal-
lation and use provided by the child
restraint's manufacturer whenever you
use such a device.
Always ensure that all occupants (of all
ages) remain properly and securely
restrained at all times.<
All rear seating positions in your vehicle
meet the recommendations of
SAE J1819, an industry recommended
standard for securing child-restraint
systems in motor vehicles.
