10. Lower the vehicle completely and tighten the
wheel nuts.
Turn the jack handle counterclockwise to lower the
vehicle.
Use only the wheel nut wrench to tighten the nuts. Do
not use other tools or any additional leverage other than
your hands, such as a hammer, pipe or your foot. Make
sure the wrench is securely engaged over the nut.
Tighten each nut a little at a time in the order shown.
Repeat the process until all the nuts are tight.
CAUTION
 When lowering the vehicle, make sure all
portions of your body and all other persons
around will not be injured as the vehicle is
lowered to the ground.
 Have the wheel nuts tightened with torque
wrench to 103 N·m (10.5 kgf·m, 76 ft·lbf.), as
soon as possible after changing wheels.
Otherwise, the nuts may loosen and the wheels
may fall off, which could cause a serious
accident.
 Do not attach a heavily damaged plastic wheel
ornament. It may fly off the wheel and cause
accidents while the vehicle is moving.
