Sheet Metal Damage
If the vehicle is damaged and requires sheet metalrepair or replacement, make sure the body repair shopapplies anti-corrosion material to parts repaired orreplaced to restore corrosion protection.
Original manufacturer replacement parts will provide thecorrosion protection while maintaining the vehiclewarranty.
Finish Damage
Any stone chips, fractures or deep scratches in thefinish should be repaired right away. Bare metalwill corrode quickly and may develop into major repairexpense.
Minor chips and scratches can be repaired with touch-upmaterials available from your dealer/retailer. Largerareas of finish damage can be corrected in yourdealer’s/retailer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dustcontrol can collect on the underbody. If these are notremoved, corrosion and rust can develop on theunderbody parts such as fuel lines, frame, floor pan,and exhaust system even though they have corrosionprotection.
At least every spring, flush these materials from theunderbody with plain water. Clean any areas where mudand debris can collect. Dirt packed in close areas ofthe frame should be loosened before being flushed.Your dealer/retailer or an underbody car washing systemcan do this.

Chemical Paint Spotting
Some weather and atmospheric conditions can create achemical fallout. Airborne pollutants can fall upon andattack painted surfaces on the vehicle. This damage cantake two forms: blotchy, ring-shaped discolorations,and small, irregular dark spots etched into thepaint surface.
Although no defect in the paint job causes this, we willrepair, at no charge to the owner, the surfaces ofnew vehicles damaged by this fallout condition within12 months or 12,000 miles (20 000 km) of purchase,whichever occurs first.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to thevehicle unless you check with your dealer/retailerfirst. Some electrical equipment can damagethe vehicle and the damage would not be coveredby the vehicle’s warranty. Some add-on electricalequipment can keep other components fromworking as they should.
Add-on equipment can drain the vehicle battery, even ifthe vehicle is not operating.
The vehicle has an airbag system. Before attempting toadd anything electrical to the vehicle, seeServicingYour Airbag-Equipped Vehicle on page 2-72andAddingEquipment to Your Airbag-Equipped Vehicle onpage 2-73.
Headlamp Wiring
The headlamp wiring system has four individual fuses.An electrical overload will cause the lamps to go onand off, or in some cases to remain off. If this happens,have the headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internalcircuit breaker. If the wiper motor overheats due toheavy snow, the wipers will stop until the motor coolsand will then restart.
A fuse powers the wiper motor. If the fuse blows, thereis an electrical problem. Be sure to have it fixed.

Power Windows and Other Power
Options
Circuit breakers in the fuse block protect the powerwindows and other power accessories. When the currentload is too heavy, the circuit breaker opens andcloses, protecting the circuit until the problem is fixed orgoes away.
Fuses and Circuit Breakers
The wiring circuits in the vehicle are protected fromshort circuits by a combination of fuses and circuitbreakers. This greatly reduces the chance of firescaused by electrical problems.
Look at the silver-colored band inside the fuse. If theband is broken or melted, replace the fuse. Be sure youreplace a bad fuse with a new one of the identicalsize and rating.
If you ever have a problem on the road and don’t havea spare fuse, you can borrow one that has the sameamperage. Just pick some feature of the vehicle that youcan get along without — like the radio or cigarettelighter — and use its fuse, if it is the correct amperage.Replace it as soon as you can.
Underhood Fuse Block
The underhood fuse block is located on the passengerside of the engine compartment. Remove the fusecover and secondary service cover to access thefuse block.
Notice:Spilling liquid on any electrical componentson the vehicle may damage it. Always keep thecovers on any electrical component.
