IN CASE OF AN EMERGENCY
406
Stop the vehicle on a level firm ground, firmly
set the parking brake and put the transmission
in “P”. Block the wheel diagonally opposite to
the one being changed if necessary.
 Make sure to set the jack properly in the jack
point. Raising the vehicle with jack improperly
positioned will damage the vehicle or may allow
the vehicle to fall off the jack and cause
personal injury.
 Never get under the vehicle when the vehicle is
supported by the jack alone.
 Use the jack only for lifting your vehicle during
wheel changing.
 Do not raise the vehicle with someone in the
vehicle.
 When raising the vehicle, do not put an object
on or under the jack.
 Raise the vehicle only high enough to remove
and change the tire.
 For vehicles equipped with the height control
switch, be sure to turn the ignition switch off
before jacking. If this is not done, the vehicle
height adjustment function will operate, which
may cause an accident.NOTICE
Do not continue driving with a deflated tire.
Driving even a short distance can damage a tire
and wheel beyond repair.
