STEERING
HYDRAULIC POWER STEERINGGUIDELINES
To help prevent damage to the powersteering system:
•Do not hold the steering wheel at itsfurthest turning points for more thanthree to five seconds when the engineis running.
•Avoid continuously steering back andforth with elevated engine RPM as thismay overheat the system. If trying tofree a stuck vehicle, pause betweenattempts to allow the power steeringsystem to cool or seek assistance.Typical steering and driving maneuversallow the system to cool.
•Do not operate the vehicle if the powersteering pump fluid level is below theMIN mark on the reservoir.
•Some noise is normal during operation.If excessive, check for low powersteering pump fluid level beforeseeking service by your dealer.
•Heavy or uneven efforts may be causedby low power steering fluid. Check forlow power steering pump fluid levelbefore seeking service by your dealer.
•Do not fill the power steering pumpreservoir above the MAX mark on thereservoir, as this may result in leaksfrom the reservoir.
If the power steering system breaks downor if you switch the engine off, you cansteer the vehicle manually, but it takesmore effort.
If you have any steering componentsserviced or replaced, install new fasteners.Many fasteners have coatings with threadadhesive, or have prevailing torquefeatures you cannot reuse. Do not reuse abolt or nut. Torque fasteners tospecifications.
Steering Tips
If the steering wanders or pulls, check for:
•An improperly inflated tire.
•Uneven tire wear.
•Loose or worn suspensioncomponents.
•Loose or worn steering components.
•Improper vehicle alignment.
Note:A high crown in the road or highcrosswinds may also make the steeringseem to wander or pull.
Electronic Torque Overlay Steering
(If Equipped)
WARNING: The electric powersteering system has diagnostic checksthat continuously monitor the system. Ifa fault is detected, a message displaysin the information display. Stop yourvehicle as soon as it is safe to do so.Switch the ignition off. After at least 10seconds, switch the ignition on andwatch the information display for asteering system warning message. If asteering system warning messagereturns, have the system checked assoon as possible.
WARNING: If the system detectsan error, you may not feel a difference inthe steering, however a serious conditionmay exist. Have your vehicle checked assoon as possible. Failure to do so mayresult in loss of steering control.

3.Reinsert the lug wrench extension(s)through the rear bumper and guidetube and turn the lug wrench clockwiseuntil the tire is raised to its stowedposition underneath the vehicle. Thewrench will become harder to turn andthe spare tire winch will ratchet or slipwhen the tire is raised to maximumtightness. You will hear a clicking soundfrom the winch indicating that the tireis properly stowed, tighten until aminimum of three clicks are heard.Check that the tire lies flat against theframe and is secure.
4.Carefully place all tools back in the toolkit bag.
5.Reinstall the tool kit bag and tightenthe wing nut.
6.Properly reinstall the jack into thebracket and tighten the wing nut.
WHEEL NUTS
WARNING: When you install awheel, always remove any corrosion, dirtor foreign materials present on themounting surfaces of the wheel or thesurface of the wheel hub, brake drum orbrake disc that contacts the wheel. Makesure to secure any fasteners that attachthe rotor to the hub so they do notinterfere with the mounting surfaces ofthe wheel. Installing wheels withoutcorrect metal-to-metal contact at thewheel mounting surfaces can cause thewheel nuts to loosen and the wheel tocome off while your vehicle is in motion,resulting in loss of vehicle control,personal injury or death.

1 Torque specifications are for nut and boltthreads free of dirt and rust. Use only ourrecommended replacement wheel nutsand or wheel bolts.
Retighten the wheel nuts to the specifiedtorque within 100 mi (160 km) after anywheel disturbance, such as tire rotation,changing a flat tire or wheel removal.
On vehicles equipped with dual rearwheels, retighten the wheel lug nuts to thespecified torque at 100 mi (160 km), andagain at 500 mi (800 km) of new vehicleoperation and after any wheel disturbance,such as tire rotation, changing a flat tire,or wheel removal.
It is important to follow the proper wheelmounting and lug nut torque procedures.
