.Slow down and adjust yourdriving according to weatherconditions. Stopping distancecan be longer and vehiclecontrol can be affected whentraction is reduced by water,snow, ice, gravel, or othermaterial on the road. Learn torecognize warning clues—suchas enough water, ice, or packedsnow on the road to make amirrored surface—and slowdown when you have any doubt.

Off-Road Driving
Four-wheel-drive vehicles can beused for off-road driving. Vehicleswithout four-wheel drive and

Before Driving Off-Road
.Have all necessary maintenanceand service work completed.
.Fuel the vehicle, fill fluid levels,and check inflation pressure inall tires, including the spare,if equipped.
.Read all the information aboutfour-wheel-drive vehicles in thismanual.
.Remove any underbody airdeflector, if equipped. Re-attachthe air deflector after off-roaddriving.
.SeeHill Descent Control(HDC)0297
.Know the local laws that apply tooff-road driving.
To g a i n m o r e g r o u n d c l e a r a n c e i fneeded, it may be necessary toremove the front fascia lower airdam. However, driving without theair dam reduces fuel economy.
