Toyota Grand Highlander (AS10): Installing the spare tire

1. Remove any dirt or foreign matter from the wheel contact surfaces and wheel nuts.

If foreign matter is on the wheel contact surface, the wheel nuts may loosen while the vehicle is in motion, causing the tire to come off.

2. Install the spare tire and loosely tighten each wheel nut by hand by approximately the same amount.

When replacing an aluminum wheel with a steel wheel, tighten the wheel nuts until the tapered portion A comes into loose contact with the disc wheel seat B.

3. Lower the vehicle.

4. Securely tighten the wheel nuts two or three times in the order shown in the illustration using a wheel nut wrench.

Vehicles with wheel locks: Tighten the wheel lock using the wheel lock key after tightening the other wheel nuts.

Tightening torque: 103 ft-lbf (140 N-m, 14.3 kgf-m)

5. Stow the flat tire, tire jack and all tools.

■The compact spare tire

• The compact spare tire is identified by the label "TEMPORARY USE ONLY" on the tire sidewall.
• Use the compact spare tire temporarily, and only in an emergency.
• Make sure to check the tire inflation pressure of the compact spare tire.

■When using the compact spare tire
