cluster displayPractical hints Car care Index Power seats, front
To operate the front power seat adjustment switches,
turn electronic key in steering lock to position 1 or 2
(with the driver’s or passenger’s door open, the power
seats can also be operated with the electronic key
removed or in steering lock 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 backrest
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 even fatal injuries. The
backrest and seat belt provide the best restraint
when the wearer is in an upright position and the
belt is properly positioned on the body.Never place hands under seat or near any moving
parts while a seat is being adjusted.
Wa r n i n g !
When leaving the vehicle, always remove the
electronic key from the steering lock, and lock your
vehicle.The power seats can also be operated with the
driver’s or 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 an accident and/or serious
personal injury.

Do not operate the power seats using the memory
button if the backrest is in an excessively reclined
position. Doing so could cause damage to front or rear
seats.
