Three-Passenger Bench Seat
When entering and exiting the vehicle, third-row passengers
must be careful that they step over the auxiliary safety restraint
system that is present with the second-row bench seat. Labels are
provided on the back of the second-row bench seat to remind
passengers to use care when exiting.
The three-passenger bench seat can be positioned in any of five
positions along the seat track. Three of these positions are for
seating and two are storage positions to accommodate varying
cargo requirements.
Arranging the Seats for Maximum Cargo Space or
Passenger Seating Flexibility
NOTE: When moving the three-passenger bench seat, the seat
cushion cannot be lowered unless the seat is in a
seating position. If you cannot get the seat cushion to
lower, you may have the seat in a storage position.
NOTE: Before re-positioning seats, remove any floor mats that
may be in the way.
