Driving in Water
{WARNING:
Driving through rushing water can be dangerous.
Deep water can sweep your vehicle downstream
and you and your passengers could drown. If it is
only shallow water, it can still wash away the
ground from under your tires, and you could lose
traction and roll the vehicle over. Do not drive
through rushing water.
Heavy rain can mean flash flooding, and flood watersdemand extreme caution.
Find out how deep the water is before driving throughit. Do not try it if it is deep enough to cover the wheelhubs, axles, or exhaust pipe—you probably will not getthrough. Deep water can damage the axle and othervehicle parts.
If the water is not too deep, drive slowly through it.At faster speeds, water splashes on the ignition systemand the vehicle can stall. Stalling can also occur if youget the tailpipe under water. If the tailpipe is underwater, you will never be able to start the engine. Whengoing through water, remember that when the brakesget wet, it might take longer to stop. SeeDriving in Rainand on Wet Roads on page 6!25.
After Off-Road Driving
Remove any brush or debris that has collectedon the underbody, chassis, or under the hood.These accumulations can be a fire hazard.
After operation in mud or sand, have the brake liningscleaned and checked. These substances can causeglazing and uneven braking. Check the body structure,steering, suspension, wheels, tires, and exhaust systemfor damage and check the fuel lines and cooling systemfor any leakage.
The vehicle requires more frequent service due tooff-road use. Refer to the Maintenance Schedule foradditional information.
Driving at Night
Night driving is more dangerous than day drivingbecause some drivers are likely to be impaired—byalcohol or drugs, with night vision problems, or byfatigue.
Night driving tips include:
.Drive defensively.
.Do not drink and drive.
.Reduce headlamp glare by adjusting the insiderearview mirror.

Other Rainy Weather Tips
Besides slowing down, other wet weather drivingtips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping equipment in good shape.
.Keep the windshield washer fluid reservoir filled.
.Have good tires with proper tread depth.SeeTires on page 7!58.
.Turn off cruise control.
Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider havingit serviced by your dealer/retailer before departing.
Things to check on your own include:
.Windshield Washer Fluid:Reservoir full?Windows clean—inside and outside?
.Wiper Blades:In good shape?
.Fuel, Engine Oil, Other Fluids:All levels checked?
.Lamps:Do they all work and are lenses clean?
.Tires:Are treads good? Are tires inflated torecommended pressure?
.Weather and Maps:Safe to travel?Have up-to-date maps?
Highway Hypnosis
Always be alert and pay attention to your surroundingswhile driving. If you become tired or sleepy, find a safeplace to park your vehicle and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep interior temperature cool.
.Keep your eyes moving—scan the roadahead and to the sides.
.Check the rearview mirror and vehicleinstruments often.

Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow or ice between thetires and the road, creating less traction or grip. Wet icecan occur at about 0°C (32°F) when freezing rainbegins to fall, resulting in even less traction. Avoiddriving on wet ice or in freezing rain until roads can betreated with salt or sand.
Drive with caution, whatever the condition. Accelerategently so traction is not lost. Accelerating too quicklycauses the wheels to spin and makes the surface underthe tires slick, so there is even less traction.
Try not to break the fragile traction. If you accelerate toofast, the drive wheels will spin and polish the surfaceunder the tires even more.
TheStabiliTrak®Systemo n p a g e 6!6improves theability to accelerate on slippery roads, but slow downand adjust your driving to the road conditions. Whendriving through deep snow, turn off the traction controlpart of the StabiliTrak®System to help maintain vehiclemotion at lower speeds.
TheAntilock Brake System (ABS)o n p a g e 6!5improves vehicle stability during hard stops on aslippery roads, but apply the brakes sooner than whenon dry pavement.
Allow greater following distance on any slippery roadand watch for slippery spots. Icy patches can occur onotherwise clear roads in shaded areas. The surfaceof a curve or an overpass can remain icy when thesurrounding roads are clear. Avoid sudden steeringmaneuvers and braking while on ice.
Turn off cruise control, if equipped, on slippery surfaces.
Blizzard Conditions
Being stuck in snow can be in a serious situation. Staywith the vehicle unless there is help nearby. If possible,use theRoadside Serviceo n p a g e 9!8. To get helpand keep everyone in the vehicle safe:
.Turn on theHazard Warning Flashersonp a g e 4!3.
.Tie a red cloth to an outside mirror.

Trailer Brakes
A loaded trailer that weighs more than 2,000 lbs(900 kg) needs to have its own brake system that isadequate for the weight of the trailer. Be sure to readand follow the instructions for the trailer brakes so theyare installed, adjusted and maintained properly.
Since the vehicle is equipped with StabiliTrak®, thetrailer brakes cannot tap into the vehicle's hydraulicsystem.
Driving with a Trailer
{WARNING:
When towing a trailer, exhaust gases may collect
at the rear of the vehicle and enter if the liftgate,
trunk/hatch, or rear-most window is open.
Engine exhaust contains carbon monoxide (CO)
which cannot be seen or smelled. It can cause
unconsciousness and even death.
To maximize safety when towing a trailer:
.Have the exhaust system inspected for
leaks and make necessary repairs before
starting a trip.
(Continued)
WARNING: (Continued)
.Never drive with the liftgate, trunk/hatch,
or rear-most window open.
.Fully open the air outlets on or under the
instrument panel.
.Adjust the Climate Control system to a setting
that brings in only outside air and set the fan
speed to the highest setting. See Climate
Control System in the Index.
For more information about carbon monoxide, see
Engine Exhaust on page 3!41.
Towing a trailer requires a certain amount ofexperience. The combination you are driving is longerand not as responsive as the vehicle itself. Getacquainted with the handling and braking of the rigbefore setting out for the open road.
Before starting, check all trailer hitch parts andattachments, safety chains, electrical connectors,lamps, tires and mirrors. If the trailer has electricbrakes, start the combination moving and then applythe trailer brake controller by hand to be sure thebrakes work.
