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).
Warning!
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 serious personal injury.
