force can be used by pressing the parking brake switch with the parking brake already
set.
*: Use wheel chocks when parking on a steep slope.

If the steering wheel becomes heavier than us ual when operating, hold firmly and oper-
ate using more force than usual.

vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pressure

●If the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, it is probable that you have a flat tire. Check the tires. If a tire is flat, change it
