5-2. Steps to take in an emergency

CAUTION

■

Using the tire jack

Improper use of the tire jack may lead to death or serious injuries due to the vehicle

suddenly falling off the jack.

●

Do not use the tire jack for any purpose other than replacing tires or installing and

removing tire chains.

●

Only use the tire jack that comes with this vehicle for replacing a flat tire.

Do not use it on other vehicles, and do not use other tire jacks for replacing tires

on this vehicle.

●

Always check that the tire jack is securely set to the jack point.

●

Do not put any part of your body under the vehicle supported by a jack.

●

Do not start or run the engine while your vehicle is supported by the jack.

●

Do not raise the vehicle while someone is in it.

●

When raising the vehicle, do not put an object on or under the jack.

●

Do not raise the vehicle to a height greater than that required to replace the tire.

●

Use a jack stand if it is necessary to get under the vehicle.

Take particular care when lowering the vehicle to ensure that no one working on or

near the vehicle may be injured.

■

Replacing a flat tire

●

Do not attach a heavily damaged wheel ornament, as it may fly off the wheel while

the vehicle is moving.

●

Failure to follow these precautions could cause the wheel nuts to loosen and the

tire to fall off, resulting in death or serious injury.

°

Never use oil or grease on the wheel bolts or wheel nuts.

Oil and grease may cause the wheel nuts to be excessively tightened, leading

to bolt or disc wheel damage. In addition, the oil or grease can cause the

wheel nuts to loosen and the wheel may fall off, causing a serious accident.

Remove any oil or grease from the wheel bolts or wheel nuts.

°

Have the wheel nuts tightened with a torque wrench to 76 ft°lbf (103 N°m,

10.5 kgf°m) as soon as possible after changing wheels.
