Engine Oil Life System
The engine oil life system calculatesengine oil life based on vehicle useand, on most vehicles, displays aDriver Information Center (DIC)message when it is necessary tochange the engine oil and filter. Theoil life system should be reset to100% only following an oil change.
Resetting the Oil Life System
To r e s e t t h e e n g i n e o i l l i f e s y s t e m :
1. Display OIL LIFE REMAININGon the DIC. SeeDriverInformation Center (DIC) (BaseLevel)0126orDriverInformation Center (DIC)(Uplevel)0129.Ifthevehicledoes not have DIC buttons, thevehicle must be in P (Park) toaccess this display.
2. Press and holdVon the DIC,
or SET/CLR on the turn signallever if the vehicle does nothave DIC buttons, for severalseconds. The oil life willchange to 100%.
The oil life system can also be resetas follows:
1. Display OIL LIFE REMAININGon the DIC. SeeDriverInformation Center (DIC) (BaseLevel)0126orDriverInformation Center (DIC)(Uplevel)0129.
2. Fully press the acceleratorpedal slowly three times withinfive seconds. If the displayshows 100%, the system isreset.

Anyobject, such as an aftermarket seatheater or a comfort-enhancing pador device, installed under or on topof the seat fabric, could alsointerfere with the operation of thepassenger sensing system. Thiscould either prevent properdeployment of the passengerairbag(s) or prevent the passengersensing system from properlyturning off the passenger airbag(s).SeePassenger SensingSystem064.
If the vehicle has rollover roof-railairbags, seeDifferent Size Tiresand Wheels0332for additionalimportant information.
If you have to modify your vehiclebecause you have a disability andyou have questions about whetherthe modifications will affect thevehicle's airbag system, or if youhave questions about whether theairbag system will be affected if thevehicle is modified for any otherreason, call Customer Assistance.SeeCustomer AssistanceOffices0385.
Airbag System Check
The airbag system does not needregularly scheduled maintenance orreplacement. Make sure the airbagreadiness light is working. SeeAirbag Readiness Light011 7.
Caution
If an airbag covering is damaged,
opened, or broken, the airbag
may not work properly. Do not
open or break the airbag
coverings. If there are any
opened or broken airbag
coverings, have the airbag
covering and/or airbag module
replaced. For the location of the

.Use of non-GM approved hooddeflectors can adversely affectthe performance of the system.Check with your dealer beforeadding equipment to the outsideof the vehicle.
Maintenance
Passenger Compartment
Air Filter
The passenger compartment airfilter reduces dust, pollen, and otherairborne irritants from outside airthat is pulled into the vehicle. Thefilter will need to be replacedperiodically. SeeMaintenanceSchedule0366.
Using the climate control systemwithout an air filter installed is notrecommended. Water or otherdebris could enter the system andresult in leaks or noises. Alwaysinstall a new filter when removingthe old filter.
For more information on filterreplacement, see your dealer.

222 Driving and Operating
Traction is reduced on hard packedsnow and ice and it is easy to losecontrol. Reduce vehicle speed whendriving on hard packed snowand ice.
{Warning
Driving on frozen lakes, ponds,
or rivers can be dangerous. Ice
conditions vary greatly and the
vehicle could fall through the ice;
you and your passengers could
drown. Drive your vehicle on safe
surfaces only.
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.
(Continued)
Warning (Continued)
Traction could be lost, and the
vehicle could roll over. Do not
drive through rushing water.
Caution
Do not drive through standing
water if it is deep enough to cover
the wheel hubs, axles, or exhaust
pipe. Deep water can damage the
axle and other vehicle parts.
If the standing water is not too deep,drive slowly through it. At fasterspeeds, water splashes and thevehicle can stall. When goingthrough water, the brakes get wetand it may take longer to stop. See“Driving on Wet Roads”later in thissection.
After Off-Road Driving
Remove any brush or debris thathas collected on the underbody orchassis, or under the hood. Theseaccumulations can be a fire hazard.
After operation in mud or sand,have the brake linings cleaned andchecked. These substances cancause glazing and uneven braking.Check the body structure, steering,suspension, wheels, tires, andexhaust system for damage andcheck the fuel lines and coolingsystem for any leakage.
More frequent maintenance serviceis required. See theMaintenanceSchedule0366.
Driving on Wet Roads
Rain and wet roads can reducevehicle traction and affect yourability to stop and accelerate.Always drive slower in these typesof driving conditions and avoiddriving through large puddles anddeep-standing or flowing water.

Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill:
1. Press the brake pedal, but donot shift into P (Park) yet. Turnthe wheels into the curb iffacing downhill or into traffic iffacing uphill.
2. Have someone place chocksunder the trailer wheels.
3. When the wheel chocks are inplace, release the regularbrakes until the chocks absorbthe load.
4. Reapply the brake pedal. Thenapply the parking brake andshift into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brakepedal.
2. Start the engine.
3. Shift into a gear.
4. Release the parking brake.
5. Let up on the brake pedal.
6. Drive slowly until the trailer isclear of the chocks.
7. Stop and have someone pickup and store the chocks.
Maintenance when Trailer
Towing
The vehicle needs service moreoften when pulling a trailer. SeeMaintenance Schedule0366.Things that are especially importantin trailer operation are automatictransmission fluid, engine oil, axlelubricant, belts, cooling system, and
brake system. It is a good idea toinspect these before and duringthe trip.
Check periodically to see that allhitch nuts and bolts are tight.
Trailer Towing
Do not tow a trailer during break-in.SeeNew Vehicle Break-In0232.
{Warning
The driver can lose control when
pulling a trailer if the correct
equipment is not used or the
vehicle is not driven properly. For
example, if the trailer is too heavy
or the trailer brakes are
inadequate for the load, the
vehicle may not stop as expected.
The driver and passengers could
be seriously injured. The vehicle
may also be damaged; the
resulting repairs would not be
covered by the vehicle warranty.
Pull a trailer only if all the steps in
this section have been followed.

to Use
The brake/hydraulic clutch fluidreservoir cap has this symbol on it.The common brake/clutch fluidreservoir is filled with DOT 3 brakefluid as indicated on the reservoircap. SeeEngine CompartmentOverview0283for reservoirlocation.
How to Check and Add Fluid
Visually check the brake/clutch fluidreservoir to make sure the fluid levelis at the MIN (minimum) line on thefront of the reservoir. The brake/hydraulic clutch fluid system shouldbe closed and sealed.
