To operate the front power seat adjustment switches,
turn the electronic key in starter switch to position 1
or 2 (with a front door open, the power seats can also be
operated with the electronic key removed or in starter
switch position 0).
Wa r n i n g !
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause the
driver to lose control of the vehicle.Never ride in a moving vehicle with the seat back
reclined. Sitting in an excessively reclined position
can be dangerous. You could slide under the seat
belt in a collision. If you slide under it, the belt
would apply force at the abdomen or neck. That
could cause serious or fatal injuries. The seat back
and seat belts provide the best restraint when the
wearer is in an upright position and belts are
properly positioned on the body.Never place hands under seat or near any moving
parts while a seat is being adjusted.
When leaving the vehicle always remove the
electronic key from the starter switch, take the
KEYLESS-GO-card (if so equipped) with you, and
lock your vehicle. The power seats can also be operated with the
driver’s or front passenger door open. Do not leave
children unattended in the vehicle, or with access
to an unlocked vehicle. Unsupervised use of vehicle
equipment may cause serious personal injury.
