STEERING

To help prevent damage to the power
steering system:
Never hold the steering wheel at its
furthest turning points (until it stops)
for more than three to five seconds
when the engine is running.
Do not operate the vehicle with a low
power steering pump fluid level (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 the engine is turned off), you can
steer the vehicle manually, but it takes
more effort.
Operating the steering system excessively
at an elevated engine RPM (>1200 rpm)
for more than 2 minutes can result in
steering system damage from overheating.
Move the steering wheel to the full left
position then full right position at idle
speed, or stop using the system for 2
minutes to allow the system to cool down.
If the power steering system exhibits heavy
or uneven efforts, check for the following
before seeking service from your dealer:
An improperly inflated tire.
Overloading of front suspension.
Uneven vehicle loading.
Binding suspension components.

An improperly inflated tire.
Uneven vehicle loading.
Uneven tire wear.
Loose or worn suspension

Loose or worn steering components.
Improper vehicle alignment.
High crosswinds.
If any steering components are serviced or

be re-used). Never re-use a bolt or nut.
Torque fasteners to specifications.
A high crown in the road or high crosswinds
may also make the steering seem to
wander or pull.
