Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.

•Power Steering System Over Temperature — If
Equipped
If the “POWER STEERING SYSTEM OVER
TEMP” message and a icon are displayed on
the EVIC screen, it indicates that extreme steer-
ing 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. After 5 minutes, the system will
cool and return to normal operation. Refer to “Power
Steering” in “Starting and Operating” for 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 your authorized dealer for
service.
EVIC Amber Telltale Lights
This area will show reconfigurable amber caution tell-
tales. These telltales include:
• Forward Collision Warning (FCW) OFF
This light warns the driver of a potential colli-
sion with the vehicle in front and prompts the
driver to take action in order to avoid the

will be in Semi Firm mode, and a green flag will light
up in the instrument cluster. The transmission will
provide a more aggressive shifting pattern (Refer to
“AutoStick” in “Starting And Operating” for further
information). This feature will reset to AUTO on an
ignition cycle.
• Snow – Tuning set for additional stability in inclement
weather. Use on and off road on loose traction surfaces
such as snow. When in Snow mode (depending on
certain operating conditions), the transmission may
use second gear (rather than first gear) during
launches, to minimize wheel slippage.
• Auto – Fully automatic full time four-wheel drive
operation can be used on and off road. Balances
traction with seamless steering feel to provide im-
proved handling and acceleration over two-wheel
drive vehicles. The active suspension system will be in
Touring Mode. •
Track – Track road calibration for use on high traction
surfaces. Driveline is maximized for traction. Some
binding may be felt on less forgiving surfaces. The
electronic brake controls are set to Partial OFF to limit
traction control management of throttle and wheel
spin.
• The transmission will be in SPORT mode and provide
a more aggressive shifting pattern. Refer to
“AutoStick” in “Starting And Operating” for further
information.
• The customer has the option of going to FULL OFF
with no interaction from the ESC System. The active
suspension system will be in Full Firm mode. A green
flag will light up in the instrument cluster.
• This feature will reset to AUTO on an ignition cycle.
• To w – Use this mode for towing. Vehicle suspension
will go to Firm mode and peak power will be limited
466 STARTING AND OPERATING

POWER STEERING
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.
WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.
470 STARTING AND OPERATING

applies the appropriate brake and may also reduce
engine power to lessen the chance that wheel lift will
occur. ERM will only intervene during very severe or
evasive driving maneuvers.
ERM can only reduce the chance of wheel lift occurring
during severe or evasive driving maneuvers. It cannot
prevent wheel lift due to other factors, such as road
conditions, leaving the roadway, or striking objects or
other vehicles.
WARNING!
Many factors, such as vehicle loading, road condi-
tions, and driving conditions, influence the chance
that wheel lift or rollover may occur. ERM cannot
prevent all wheel lift or rollovers, especially those
that involve leaving the roadway or striking objects

WARNING!(Continued)
or other vehicles. The capabilities of an ERM-
equipped vehicle must never be exploited in a reck-
less or dangerous manner, which could jeopardize
the user’s safety or the safety of others.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel to assist in
counteracting the oversteer or understeer condition. En-
gine power may also be reduced to help the vehicle
maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
