Driving and Operating 8-5
If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. If the brakes are pumped,
the pedal could get harder to push
down. If the engine stops, there will
still be some power brake assist but
it will be used when the brake is
applied. Once the power assist is
used up, it can take longer to stop
and the brake pedal will be harder
to push.
Adding non‐dealer/non‐retailer
accessories can affect vehicle
performance. SeeAccessories
and Modifications on page 9‑3.
Steering
Electric Power Steering
(2.4L L4 Engine)
If the engine stalls while driving, the
power steering assist system will
continue to operate until you are
able to stop the vehicle. If power steering assist is lost because the
electric power steering system is not
functioning, the vehicle can be
steered but it will take more effort.
If you turn the steering wheel in
either direction several times until
it stops, or hold the steering wheel
in the stopped position for an
extended amount of time, you may
notice a reduced amount of power
steering assist. The normal amount
of power steering assist should
return shortly after a few normal
steering movements.
The electric power steering
system does not require regular
maintenance. If you suspect
steering system problems, such as
abnormally high steering effort for a
prolonged period of time, contact
your dealer/retailer for service
repairs.
Hydraulic Power Steering
(3.0L V6 Engine)
If power steering assist is lost
because the engine stops or the
power steering system is not
functioning, the vehicle can be
steered but it will take more effort.
Steering Tips
It is important to take curves at a
reasonable speed.
Traction in a curve depends on the
condition of the tires and the road
surface, the angle at which the
curve is banked, and vehicle speed.
While in a curve, speed is the one
factor that can be controlled.
If there is a need to reduce speed,
do it before entering the curve, while
the front wheels are straight.
Try to adjust the speed so you can
drive through the curve. Maintain a
reasonable, steady speed. Wait to
accelerate until out of the curve, and
then accelerate gently into the
straightaway.

8-8 Driving and Operating
Many of the vehicle design features
that help make the vehicle more
responsive on paved roads during
poor weather conditions also help
make it better suited for off‐road use
than conventional passenger
vehicles. The vehicle does not have
features usually thought to be
necessary for extended or severe
off‐road use such as special
underbody shielding and transfer
case low gear range.
The airbag system is designed to
work properly under a wide range of
conditions, including off‐road usage.
Always wear your safety belt and
observe safe driving speeds,
especially on rough terrain.
Drinking and driving can be very
dangerous on any road and this is
certainly true for off-road driving.
At the very time you need special
alertness and driving skills, your
reflexes, perceptions, and judgmentcan be affected by even a small
amount of alcohol. You could have a
serious
—or even fatal —accident
if you drink and drive or ride with a
driver who has been drinking.
Off-roading can be great fun but has
some definite hazards. The greatest
of these is the terrain itself. When
off-road driving, traffic lanes are not
marked, curves are not banked, and
there are no road signs. Surfaces
can be slippery, rough, uphill,
or downhill.
Avoid sharp turns and abrupt
maneuvers. Failure to operate the
vehicle correctly off‐road could
result in loss of vehicle control or
vehicle rollover.
Off-roading involves some new
skills. That is why it is very
important that you read these
driving tips and suggestions to help
make off-road driving safer and
more enjoyable.Before You Go Off-Roading
.Have all necessary maintenance
and service work done.
.Make sure there is enough fuel,
that fluid levels are where they
should be, and that the spare
tire is fully inflated.
.Be sure to read all the
information about all-wheel-drive
vehicles in this manual.
.Make sure all underbody
shields, if the vehicle has them,
are properly attached.
.Know the local laws that apply to
off-roading where you will be
driving or check with law
enforcement people in the area.
.Be sure to get the necessary
permission if you will be on
private land.

Driving and Operating 8-31
Engine Coolant Heater
The engine coolant heater,
if available, can help in cold weather
conditions at or below−18°C (0°F)
for easier starting and better fuel
economy during engine warm-up.
Plug in the coolant heater at least
four hours before starting the
vehicle. An internal thermostat in
the plug-end of the cord will prevent
engine coolant heater operation at
temperatures above −18°C (0°F).
To Use The Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
The electrical cord is located on
the passenger side of the engine
compartment, in front of the air
cleaner.
3. Plug it into a normal, grounded 110-volt AC outlet.
{WARNING
Plugging the cord into an
ungrounded outlet could cause an
electrical shock. Also, the wrong
kind of extension cord could
overheat and cause a fire. You
(Continued)
WARNING (Continued)
could be seriously injured. Plug
the cord into a properly grounded
three-prong 110-volt AC outlet.
If the cord will not reach, use a
heavy-duty three-prong extension
cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and store the
cord as it was before to keep it
away from moving engine parts.
If you do not it could be
damaged.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer/retailer
in the area where you will be
parking the vehicle for the best
advice on this.

Driving and Operating 8-49
System Settings
Each time the vehicle is started
URPA defaults to the On setting.
Use theVehicle Personalization
on
page 4‑36menu to
configure URPA.
The settings are:
.On: Turns URPA on
.Off: Turns URPA off
.Tow Bar: Use when a tow bar is
attached to the vehicle
Tow Bar
When the tow bar setting is used,
an area of 16 cm (6 in) around the
hitch is not detected by the system.
When the System Does Not
Seem to Work Properly
If the URPA system does not
activate due to a temporary
condition, the message Park Assist
Off displays on the DIC and a red
light is shown on the rear URPA
display when the shift lever is
moved into R (Reverse). This can
occur under the following
conditions:
.The ultrasonic sensors are not
clean. Keep the vehicle's rear
bumper free of mud, dirt, snow,
ice and slush. For cleaning
instructions, see Exterior Care
on page 9‑85.
.A trailer was attached to the
vehicle, or an object was
hanging out of the liftgate during
the last drive cycle, a red light
may come on in the rear display.
Once the attached object is
removed, URPA will return to
normal operation.
.A tow bar is attached to the
vehicle and the tow bar setting is
not being used, or an odd
shaped tow bar is attached to
the vehicle and the tow bar
setting is being used.
.The vehicle's bumper is
damaged. Take the vehicle to
your dealer/retailer to repair the
system.
.Other conditions may affect
system performance, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck.
If the system is still disabled, after
driving forward at least 25 km/h
(15 mph), take the vehicle to your
dealer/retailer.
