Other Maintenance
Rems
Front Suspension and Steering Linkage
Refer to the Maintenance Schedule to determine how often to lubricate the
fittings and what type of lubricant to use.
Front Wheel Bearing (Two-Wheel Drive)
If your vehicle is two-wheel drive, it has wheel bearings that must be
cleaned and repacked.
Refer to the Maintenance Schedule to determine how often this must be
done.
Single Belt Accessory Drive
Your new vehicle uses a serpentine belt that is lighter, and more durable
than systems with several belts.
The belt runs over or around the pulleys on the engine. A tensioner is used
to keep the belt tight at all times. The tensioner also makes replacing the
belt easier. If you need to replace the belt, be sure to get the correct
replacement belt. Your dealership or parts supplier can help you with this.
The Accessory Drive Belt Routing label on your vehicle will show you how
to route the belt your vehicle uses.
Windshield Wiper Blade Inserts
To replace your
windshield wiper
blade inserts, lift the
wiper arm away from
the windshield. Pinch
the two tabs on the
wiper arm and slide
the insert out of the
blade. Slide the new
one in place. Make
sure the tabs are
locked into position.
