Wheel Replacement
If you need to change the wheel during the journey, choose
a safe place to stop your vehicle away from the main road
if possible. Always ask your passengers to get out of the
car and wait in a safe area away from other traffic.
Switch on hazard warning lamps. If available, position
a warning triangle about 50 to 150 metres behind your
vehicle to warn approaching traffic.
Before changing a wheel, ensure the front wheels are in the
straight ahead position. Apply the parking brake and place
the gear shift lever of transmission in N position (manual
transmission) or P position (automatic transmission).
Observe the following precautions:
• Ensure the jack is positioned on firm, level ground.
• If the vehicle must be parked on the hill, place chocks
in front of and behind other 3 wheels to prevent the
vehicle from moving.

Emergency Information
Positioning the Jack
Position the jack on firm level ground under the jacking
point nearest the wheel to be removed. Note that the
rectangle groove of the jack must fit into the corresponding
flanging of the body (see illustration).
NEVER work beneath the car with the jack
as the only means of support. The jack is
designed for wheel replacement only!
NEVER jack the car using any positions other
than the jacking points. Serious damage to
the car could result.
Avoid accidental contact with any underbody
parts, especially hot
components.
