and left the vehicle without the
vehicle being shut off.
The feature can be turned on or off.
See Vehicle Personalization 0 167 .

CautionFolding a rear seat with the safety
belts still fastened may cause
damage to the seat or the safety
belts. Always unbuckle the safety
belts and return them to their
normal stowed position before
folding a rear seat.
