TYRE ROTATION
Front and rear tyres perform different jobs
and can wear differently.
Normally, the front tyres will wear faster
than rear tyres. To prolong the life of your
tyres and avoid uneven tread wear:
1. Rotate tyres every 7,500 kms.
2. Maintain proper tyre pressure.
3. Check tightening of the lug nuts/bolts.
See "HOW TO CHANGE A FLAT TYRE"
on page 6-3.

WARNING
• Use the recommended wheels and
wheel lug nuts/bolts only.
Otherwise, you can lose control of
your vehicle and cause a collision that
can result in injuries or damage to
your vehicle or other property.
