Before Driving Off-Road
• Have all necessary maintenance and service work completed.
• Fuel the vehicle, fill fluid levels, and check inflation pressure in all tires, including the spare, if equipped.
• Read all the information about four-wheel-drive vehicles in this manual.
• Make sure all underbody shields, if equipped, are properly attached.
• Know the local laws that apply to off-road driving.
To gain more ground clearance if needed, it may be necessary to remove the front fascia lower air dam.
Notice: Operating the vehicle for extended periods without the front fascia lower air dam installed can cause improper air flow to the engine. Re-attach the front fascia air dam after off-road driving.
