Changing a wheel

WARNING

Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training. The jack provided with your vehicle is designed only for changing a flat tire. If it is used for anything else, you or others could be badly injured or killed if the vehicle slips off the jack. Use the jack provided with your vehicle only for chang- ing a flat tire.

Changing a tire can be dangerous. The vehicle can slip off the jack and roll over or fall on you or other people. You and they could be badly injured or even killed. Find a level place to change your tire. To help prevent the vehicle from moving:

1Set the parking brake firmly.

2If you have an automatic transmis- sion, put the shift lever in PARK (P). For a manual transmission, leave the car in gear (1st or REVERSE (R)).

3Turn off the engine and do not restart while the vehicle is raised.

4Do not allow passengers to remain in the vehicle.

To be even more certain the vehicle won't move, you should put blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire, on the other side, at the opposite end of the vehicle.

The car jack is designed solely for use in changing a wheel or fitting snow chains. It must not be used to sup- port the car during repair work or servicing.

Never crawl under a car that is supported only by a jack.

Raising your vehicle too high or with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit the jack lift head into the proper location before raising the vehicle, and raise the vehicle only far enough off the ground so there is enough room for the spare tire to fit (no more than 25 mm or 1 inch clearance between the ground and the bottom of the tire).

Switch on the hazard warning lights if the car is on a road.

The jack should be stored correctly under the carpeting in the trunk. If it lies loose in the car, it could thrown for- ward and cause personal injury in the event of a crash or if the car rolls over.

Grit, salt and rust can clog the inner threads of the wheel bolts if the car has been driven for several years exclu- sively with alloy wheels.

If steel wheels are being installed, the bolt hole threads in the brake hubs should be cleaned before the thinner steel wheels are fitted. It may other- wise not be possible to achieve the correct clamping force, despite tight- ening the wheel bolts to the correct torque.
