Anti-Pinch Feature
If an object is in the path of the

Dirt and debris may collect on the
sunroof seal or in the track. This
could cause an issue with sunroof
operation, noise, or plugging the
water drainage system. Periodically
open the sunroof and remove any
obstacles or loose debris. Wipe the
sunroof seal and roof sealing area
using a clean cloth, mild soap, and
water. Do not remove grease from
the sunroof.

restraints in the outboard seating
positions.

Reclining Seatbacks
{WARNING
Sitting in a reclined position when
the vehicle is in motion can be
dangerous. Even when buckled
up, the safety belts cannot do
their job when reclined like this.
The shoulder belt cannot do its
job because it will not be against
your body. Instead, it will be in
front of you. In a crash, you could
go into it, receiving neck or other
injuries.
The lap belt cannot do its job
either. In a crash, the belt could
go up over your abdomen. The
belt forces would be there, not at
your pelvic bones. This could
cause serious internal injuries. (Continued)
WARNING (Continued)
For proper protection when the
vehicle is in motion, have the
seatback upright. Then sit well
back in the seat and wear the
safety belt properly.
Do not have a seatback reclined if
the vehicle is moving.
