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 all-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.
