After Off-Road Driving
Remove any brush or debris that has collected on the underbody or chassis, or under the hood. These accumulations can be a fire hazard.
After operation in mud or sand, have the brake linings cleaned and checked. These substances can cause glazing and uneven braking.
Check the body structure, steering, suspension, wheels, tires, and exhaust system for damage and check the fuel lines and cooling system for any leakage.
More frequent maintenance service is required. Refer to the Maintenance Schedule for more information.
