STARTING AND OPERATING 391

POWER STEERING
3.6L Engine
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 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.
CAUTION!
Extreme steering maneuvers may cause the electri-
cally driven pump to reduce or stop power steering
assistance in order to prevent damage to the system.
Normal operation will resume once the system is
allowed to cool.If the “SERVICE POWER STEERING” message
and a flashing icon are displayed on the EVIC
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 “Elec-
tronic Vehicle Information (EVIC)” in “Understanding
Your Instrument Panel” for further information.
If the “POWER STEERING HOT” message and an icon
are displayed on the EVIC 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 “Electronic Vehicle Information
(EVIC)” in “Understanding Your Instrument Panel” for
further information.
440 STARTING AND OPERATING

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 your authorized dealer for
service.
5.7L Engine
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost. If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:
•
Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
• Upon initial start-up in cold weather, the power steer-
ing pump may make noise for a short amount of time.
This is due to the cold, thick fluid in the steering
system. This noise should be considered normal, and it
does not in any way damage the steering system.

STARTING AND OPERATING 441

CAUTION!
If the “Brake Warning Light” remains on with the
parking brake released, a brake system malfunction
is indicated. Have the brake system serviced by an
authorized dealer immediately.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that includes the Anti-Lock Brake
System (ABS), Traction Control System (TCS), Brake
Assist System (BAS), Electronic Roll Mitigation (ERM),
and Electronic Stability Control (ESC). All five of these
systems work together to enhance vehicle stability and
control in various driving conditions.Also, your vehicle may be equipped with Trailer Sway
Control (TSC), Hill Start Assist (HSA), Ready Alert
Braking (RAB), Rain Brake Support (RBS) and, if it has
four-wheel drive with the MP 3023 two-speed transfer
case, Hill Descent Control (HDC), Selec Speed Control
(SSC).
Anti-Lock Brake System
The Anti-Lock Brake System (ABS) is designed to aid the
driver in maintaining vehicle control under adverse
braking conditions. The system operates with a separate
computer to modulate hydraulic pressure to prevent
wheel lock-up and help avoid skidding on slippery
surfaces.
All vehicle wheels and tires must be the same size and
type, and tires must be properly inflated to produce
accurate signals for the computer.
446 STARTING AND OPERATING

WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will maintain
the level of brake pressure the driver applied for a short
period of time after the driver takes their foot off of the
brake pedal. If the driver does not apply the throttle
during this short period of time, the system will release
brake pressure and the vehicle will roll down the hill. The
system will release brake pressure in proportion to the
amount of throttle applied as the vehicle starts to move in
the intended direction of travel.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
•Vehicle must be stopped.
• Vehicle must be on a 6% (approximate) grade or
greater hill.
• Gear selection matches vehicle uphill direction (i.e.,
vehicle facing uphill is in forward gear; vehicle back-
ing uphill is in REVERSE gear).
HSA will work in REVERSE and all forward gears when
the activation criteria have been met. The system will not
activate if the vehicle is placed in NEUTRAL or PARK.
454 STARTING AND OPERATING

Disabling SSC
SSC will deactivate and be disabled if any of the follow-
ing conditions occur:
•The driver presses the SSC switch
• The driveline is shifted out of 4WD Low Range.
• The parking brake is applied.
• Driver door opens.
• The vehicle is driven faster than 20 mph (32 km/h) for
longer than 70 seconds.
• The vehicle is driven greater than 40 mph (64 km/h) (
SSC exits immediately)
Feedback to the driver:
The instrument cluster has an SSC icon and the SSC
switch has an LED which offers feedback to the driver
about the state SSC is in. •
The cluster icon and switch lamp will illuminate and
remain on solid when SSC is enabled or activated. This
is the normal operating condition for SSC.
• The cluster icon and switch lamp will flash for several
seconds then extinguish when the driver presses the
SSC switch but enable conditions are not met.
• The cluster icon and switch lamp will flash for several
seconds then extinguish when SSC deactivates due to
excess speed.
WARNING!
SSC is only intended to assist the driver in control-
ling vehicle speed when driving in off road condi-
tions. The driver must remain attentive to the driving
conditions and is responsible for maintaining a safe
vehicle speed.

STARTING AND OPERATING 463

Spare Tire Stowage
The spare tire is stowed under the load floor in the rear
cargo area and is secured to the body with a special wing
nut.
Preparations For Jacking
CAUTION!
Always lift or jack the vehicle from the correct
jacking points. Failure to follow this information
could cause damage to the vehicle or underbody
components.
NOTE: To assist with changing a spare tire, the air
suspension system has a feature which allows the auto-
matic leveling to be disabled.
1. Park the vehicle on a firm, level surface. Avoid ice or slippery surfaces.
WARNING!
Do not attempt to change a tire on the side of the
vehicle closest to moving traffic, pull far enough off
the road to avoid being hit when operating the jack
or changing the wheel.
2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Place the shift lever into PARK.
5. Turn the ignition OFF.
