292 Vehicle Care
Body Component Lubrication
Lubricate all key lock cylinders,hood hinges, liftgate hinges, and thefuel door hinge unless thecomponents are plastic. Applyingsilicone grease on weatherstripswith a clean cloth will make themlast longer, seal better, and not stickor squeak.
Underbody Maintenance
At least twice a year, spring and fall,use plain water to flush dirt anddebris from the vehicle's underbody.Yo u r d e a l e r o r a n u n d e r b o d y c a rwashing system can do this. If notremoved, rust and corrosion candevelop.
Do not directly power wash thetransfer case and/or front/rear axleoutput seals. High pressure watercan overcome the seals andcontaminate the fluid. Contaminatedfluid will decrease the life of thetransfer case and/or axles andshould be replaced.
Sheet Metal Damage
If the vehicle is damaged andrequires sheet metal repair orreplacement, make sure the bodyrepair shop applies anti-corrosionmaterial to parts repaired orreplaced to restore corrosionprotection.
Original manufacturer replacementparts will provide the corrosionprotection while maintaining thevehicle warranty.
Finish Damage
Quickly repair minor chips andscratches with touch-up materialsavailable from your dealer to avoidcorrosion. Larger areas of finishdamage can be corrected in yourdealer's body and paint shop.
Chemical Paint Spotting
Airborne pollutants can fall uponand attack painted vehicle surfacescausing blotchy, ring-shapeddiscolorations, and small, irregulardark spots etched into the paintsurface. See“Finish Care”previously in this section.
