CAUTION
When using the lower anchorages for the child
restraint system, be sure that there are no irregular
objects around the anchorages or that the seat belt is
not caught.
 Push and pull the child restraint system in different
directions to be sure it is secure. Follow all the
installation instructions provided by its
manufacturer.
 Do not install a child restraint system on the rear seat
if it interferes with the lock mechanism of the front
seats. This can cause death or serious injury to the
child and front passenger in case of sudden braking
or a collision.
DRIVING POSITION MEMORY SYSTEM
The microcomputer can memorize the positions of the driver’s
seat and outside rear view mirrors. Two different driving
position profiles can be entered into the computer’s memory.
Recording a driving position in the computer’s memory can
only be done when the ignition key is in the “ON” position and
the selector lever is in the “P” position.
Setting the driving position
1. Adjust the driver’s seat and outside rear view mirrors
to the desired position.
2. While pushing the “SET” button, push button “1” or “2”
until the signal beeps.
The beep sound means that the positions are recorded in the
computer’s memory.

By repeating these two steps
and pressing the remaining
button, the driving position for another driver can be recorded.
To set a new memorized position, select the desired position
and perform step 2. The previous memory will be erased and
the new position will be set.
To make only slight changes to an already memorized position,
the easiest way is to first activate the memorized position, then
make the desired changes and perform step 2 above.
Recalling the memorized position
When you push button “1” or “2”, the driving position will
be automatically adjusted to the position recorded for that
button. Conditions for memorized position activation

Ignition key “ON” and selector lever in “P” position.
 Ignition switch off and within 30 seconds of opening driver’s
door.
If any driving position memory switch is pushed while one of
the memorized driving position profiles is being activated, the
operation will stop.
To activate the system, push the desired button (“1” or “2”)\
again.
The driving position memory control system cannot be
operated while the vehicle is moving.
If the vehicle’s battery is disconnected, the computer’s
memory wi ll be erased and the memorized positions will have
to be set again.
CAUTION
 Do not start the vehicle while the adjustments are
being made.
 Take care not to select the wrong button, or the seat
could strike the rear passenger or hit your body
against the steering wheel. If this happens, you can
stop the movement by pressing another driving
position memory switch.

sound an alarm if any of the doors, trunk or hood is
forcibly unlocked or the battery terminal is disconnected
and then reconnected while the vehicle is locked.
The alarm blows the horn intermittently and flashes the
headlights, tail lights and turn signal lights.
Further more when the interior light switch is in the “DOOR”
position, the interior light turns on.

an ignition key or wireless remote control, the tail lights turn on
for about 2 seconds to inform you that the system was
activated.
