SEATS AND RESTRAINTS

If your vehicle has rear head restraints that fold down, always return them to the full upright position whenever an occupant is seated in the seat.  Adjust the head restraint so that the top of the restraint is at the same height as the top of the occupant’s head.

The lap belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones. This could cause serious internal injuries.
For proper protection when the vehicle is in motion, have the seatback upright. Then sit well back in the seat and wear the seat belt properly.

Memory Seats

If equipped, memory seats allow two drivers to store and recall their unique seat positions for driving the vehicle, and a shared exit position for getting out of the vehicle.

A Driver Information Center (DIC) welcome
message indicating the transmitter number may display for the first few ignition cycles following a transmitter change.

Warning
If temperature change or pain to the skin cannot be felt, the seat heater may cause burns. To reduce the risk of burns, use care when using the seat heater, especially for long periods of time. Do not place anything on the seat that insulates against heat, such as a blanket, cushion, cover, or similar item. This may cause the seat heater to overheat. An overheated seat heater may cause a burn or may damage the seat.

Auto Heated and Ventilated Seats
If the vehicle is equipped with auto-heated or ventilated seats, and the ignition is on, this feature will automatically activate the heated or ventilated seats at the level required by the vehicle’s interior temperature.

Use the manual heated and ventilated seat buttons on the center stack to turn auto-heated or ventilated seats off. If the passenger seat is unoccupied, the auto-heated or ventilated seats feature will not activate that seat. The auto-heated and ventilated seats feature can be programmed to always be enabled when the vehicle is on. If equipped with a heated steering wheel, the auto-heated steering wheel activation will follow the heated seat auto-activation and the heated wheel indicator will follow the state of the steering wheel heat.
