Wheel nuts must be installed and maintained at the proper torque to prevent loose
wheels, broken studs, and possible dangerous separation of wheel from the axle. Be
sure to use only the nuts matched to the cone angle of the wheel.

torque wrench to tighten the fasteners. If you do not have a torque wrench, tighten the
fasteners with a lug wrench, then immediately have a service garage or dealer tighten

threads or nuts.
2. Tighten nuts in the following sequence:
