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.
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
If any steering components are serviced or
replaced, install new fasteners (many are
coated with thread adhesive or have
prevailing torque features which may not
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.
Adaptive Steering (If Equipped)
Note: The adaptive steering system has
diagnostic checks that continuously monitor
the system. If a fault is detected a message
displays in the information display. If a red
warning message displays, stop your vehicle
as soon as it is safe to do so. The message
may clear if the fault is no longer present. If
an adaptive steering system warning
message appears each time you start your
vehicle, have the system checked as soon
as possible.
The adaptive steering system continually
changes the steering ratio with changes to
vehicle speed, optimizing the steering
response in all conditions. The system also
changes when you switch on the
transmission tow/haul feature. When you
select the tow/haul button, the adaptive
steering system reduces vehicle sensitivity
to steering inputs at higher vehicle speeds,
while maintaining the ease of parking and
maneuverability at low speeds.
Note: The adaptive steering system is
designed with a locking device. With the
lock engaged, the adaptive steering system
remains mechanically locked at a fixed
steering ratio. You may also notice a click
when you switch the vehicle on or after you
switch it off, as the lock disengages or
engages.
Note: If your vehicle loses electrical power
or detects a fault when you are driving, the
system automatically shuts down and you
retain normal steering function with a fixed
steering ratio. During this time it is possible
that the steering wheel may not be straight
when the vehicle is driving straight ahead.
In addition, the driver may notice that the
steering wheel angle required to steer the
vehicle may be different.
Note: During parking maneuvers, the
adaptive steering system balances the driver
work load for various steering wheel inputs
and vehicle loading conditions. Under
extreme operating conditions the system
locking device may engage. This strategy
prevents overheating and permanent
damage to the adaptive steering system.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
