STARTING AND OPERATING 177
Push the SWAY BAR switch to activate the system. Push
the switch again to deactivate the system. The “Sway Bar
Indicator Light” (located in the instrument cluster) will
illuminate when the bar is disconnected. The “Sway Bar
Indicator Light” will flash during activation transition, or
when activation conditions are not met. The stabilizer/
sway bar should remain in on-road mode during normal
driving conditions.
To disconnect the stabilizer/sway bar, shift to either 4H or
4L and push the SWAY BAR switch to obtain the off-road
position. Refer to “Four-Wheel Drive Operation” in this
section for further information. The “Sway Bar Indicator
Light” will flash until the stabilizer/sway bar has been fully
disconnected.
NOTE:
The stabilizer/sway bar may be torque locked due to left
and right suspension height differences. This condition is
due to driving surface differences or vehicle loading. In
order for the stabilizer/sway bar to disconnect/reconnect,
the right and left halves of the bar must be aligned. This
alignment may require that the vehicle be driven onto level
ground or rocked from side to side.
To return to on-road mode, push the SWAY BAR switch
again.
ELECTRO-HYDRAULIC POWER STEERING
Your vehicle is equipped with an electro-hydraulic power
steering system that will give you good vehicle response
and increased ease of maneuverability in tight spaces.
The system will vary its assist to provide light efforts while
parking and a good feel while driving. If the electro-
hydraulic power steering system experiences a fault that
prevents it from providing power steering assist, then the
system will provide mechanical steering capability.
If the “SERVICE POWER STEERING” message
and a flashing icon are displayed on the
instrument cluster screen, it indicates that the
vehicle needs to be taken to the dealer for
service. It is likely the vehicle has lost power steering
assistance. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel for further
information.
If the “POWER STEERING HOT” message and an icon are
displayed on the instrument cluster screen, it indicates
that extreme steering maneuvers may have occurred,
which caused an over temperature condition in the power
steering system. You will lose power steering assistance
momentarily until the over temperature condition no
longer exists. Once driving conditions are safe, then pull
over and let vehicle idle for a few moments until the light
turns off. Refer to “Instrument Cluster Display” in “Getting
To Know Your Instrument Panelfor further information.
NOTE:
Even if power steering assistance is no longer opera-
tional, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at very low vehicle speeds
and during parking maneuvers.
If the condition persists, see an authorized dealer for
service.
WARNING!
Ensure the stabilizer/sway bar is reconnected before driv-
ing on hard surfaced roads or at speeds above 18 mph
(29 km/h); a disconnected stabilizer/sway bar may con-
tribute to the loss of vehicle control, which could result in
serious injury. Under certain circumstances, the front sta-
bilizer/sway bar enhances vehicle stability and assists
with vehicle control. The system monitors vehicle speed
and will attempt to reconnect the stabilizer/sway bar at
speeds over 18 mph (29 km/h). This is indicated by a
flashing or solid “Sway Bar Indicator Light.” Once vehicle
speed is reduced below 14 mph (22 km/h), the system
will once again attempt to return to off-road mode.
WARNING!
If the stabilizer/sway bar will not return to on-road mode,
the “Sway Bar Indicator Light” will flash in the instrument
cluster and vehicle stability may be reduced. Do not
attempt to drive the vehicle over 18 mph (29 km/h).
Driving faster than 18 mph (29 km/h) with a discon-
nected stabilizer/sway bar may contribute to the loss of
vehicle control, which could result in serious injury.
CAUTION!
Extreme steering maneuvers may cause the electrically
driven pump to reduce or stop power steering assistance
in order to prevent damage to the system. Normal opera-
tion will resume once the system is allowed to cool.
