STEERING
Hydraulic Power Steering
To help prevent damage to the power
steering system:
•
Do not hold the steering wheel at its
furthest turning points for more than
three to five seconds when the engine
is running.
• Avoid continuously steering back and
forth with elevated engine RPM as this
may overheat the system. If trying to
free a stuck vehicle, pause between
attempts to allow the power steering
system to cool or seek assistance.
Typical steering and driving maneuvers
allow the system to cool.
• Do not operate the vehicle if the power
steering pump fluid level is below the
MIN mark on the reservoir.
• Some noise is normal during operation.
If excessive, check for low power
steering pump fluid level before
seeking service by your dealer.
• Heavy or uneven efforts may be caused
by low power steering fluid. Check for
low power steering pump fluid level
before seeking service by your dealer.
• Do not fill the power steering pump
reservoir above the MAX mark on the
reservoir, as this may result in leaks
from the reservoir.
If the power steering system breaks down
or if you switch the engine off, you can
steer the vehicle manually, but it takes
more effort.
If you have any steering components
serviced or replaced, install new fasteners.
Many fasteners have coatings with thread
adhesive, or have prevailing torque
features you cannot reuse. Do not reuse a
bolt or nut. Torque fasteners to
specifications. Steering Tips
If the steering wanders or pulls, check for:
•
An improperly inflated tire.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Electronic Torque Overlay Steering
(If Equipped) WARNING: The electric power
steering system has diagnostic checks
that continuously monitor the system. If
a fault is detected, a message displays
in the information display. Stop your
vehicle as soon as it is safe to do so.
Switch the ignition off. After at least 10
seconds, switch the ignition on and
watch the information display for a
steering system warning message. If a
steering system warning message
returns, have the system checked as
soon as possible. WARNING:
If the system detects
an error, you may not feel a difference in
the steering, however a serious condition
may exist. Have your vehicle checked as
soon as possible. Failure to do so may
result in loss of steering control.

TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications
WARNING: When you install a wheel, always remove any corrosion, dirt or foreign
materials present on the mounting surfaces of the wheel or the surface of the wheel
hub, brake drum or brake disc that contacts the wheel. Make sure to secure any fasteners
that attach the rotor to the hub so they do not interfere with the mounting surfaces of
the wheel. Installing wheels without correct metal-to-metal contact at the wheel
mounting surfaces can cause the wheel nuts to loosen and the wheel to come off while
your vehicle is in motion, resulting in loss of vehicle control, personal injury or death. lb.ft (Nm)

recommended replacement fasteners.
On vehicles equipped with single rear wheels, retighten the lug nuts to the specified torque
at 100 mi (160 km) after any wheel disturbance, such as tire rotation, changing a flat tire,
or wheel removal.
On vehicles equipped with dual rear wheels, retighten the wheel lug nuts to the specified
torque at
100 mi (160 km), and again at 500 mi (800 km) of new vehicle operation and
after any wheel disturbance, such as tire rotation, changing a flat tire, or wheel removal.
It is important to follow the proper wheel mounting and lug nut torque procedures. Wheel pilot bore

Inspect the wheel pilot hole and
mounting surface prior to installation.
Remove any visible corrosion or loose
particles.
