Vehicle Preparation

- Remove the excessive ice and/or mud from under the fenders.
- Inflate the tires to the specified pressures.
- See that the vehicle contains no load other than the driver in a normal position.
- Be sure the lenses are clean; check for burned-out bulbs and proper beam switching. Headlamps with cracked or broken aiming pads, lenses, or visible moisture on the interior should be replaced.
- Check the suspension. Verify that the vehicle does not lean to one side or the other. Rock the vehicle sideways to free and equalize the suspension.
