SAFETY 99
(Continued)
Electronic Stability Control (ESC)
Electronic Stability Control (ESC) enhances directional
control and stability of the vehicle under various driving
conditions. ESC corrects for over/under steering of the
vehicle by applying the brake of the appropriate wheel to
assist in counteracting the over/under steer condition.
Engine power may also be reduced to help the vehicle main-
tain 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 the intended path, ESC applies the brake of the appropriate
wheel to assist in counteracting the oversteer or understeer
condition.
• Oversteer - when the vehicle is turning more than appro
-
priate for the steering wheel position.
• Understeer - when the vehicle is turning less than appro -
priate for the steering wheel position.
WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. BAS cannot prevent collisions, including
those resulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. The capabilities
of a BAS-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopardize
the user's safety or the safety of others.
WARNING!
• Electronic Stability Control (ESC) cannot prevent the natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. ESC cannot prevent accidents, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. ESC also
cannot prevent accidents resulting from loss of vehicle
control due to inappropriate driver input for the condi -
tions. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ESC equipped
vehicle must never be exploited in a reckless or
dangerous manner which could jeopardize the user’s
safety or the safety of others.4

SAFETY 101
Electronic Roll Mitigation (ERM)
Electronic Roll Mitigation (ERM) anticipates the potential for
wheel lift by monitoring the driver’s steering wheel input
and the speed of the vehicle. When ERM determines that the
rate of change of the steering wheel angle and vehicle’s
speed are sufficient to potentially cause wheel lift, it then
applies the appropriate brake and may also reduce engine
power to lessen the chance that wheel lift will occur.
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.Hill Start Assist (HSA)
Hill Start Assist (HSA) 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:
• The vehicle must be stopped.
• The vehicle must be on a 5% (approximate) grade or
greater hill.
• Gear selection matches vehicle uphill direction (i.e., vehicle facing uphill is in forward gear; vehicle backing
uphill is in REVERSE (R) 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 (N) or PARK (P).

WARNING!
Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or roll overs, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which could
jeopardize the user's safety or the safety of others.

SAFETY 131
Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending on
the nature of the event, the ORC will determine whether to
have the Enhanced Accident Response System perform the
following functions:
• Cut off fuel to the engine (if equipped)
• Cut off battery power to the electric motor (if equipped)
• Flash hazard lights as long as the battery has power
• Turn on the interior lights, which remain on as long as thebattery has power or for 15 minutes from the intervention
of the Enhanced Accident Response System
• Unlock the power door locks
Your vehicle may also be designed to perform any of these
other functions in response to the Enhanced Accident
Response System:
• Turn off the Fuel Filter Heater, Turn off the HVAC Blower Motor, Close the HVAC Circulation Door • Cut off battery power to the:
• Engine
• Electric Motor (if equipped)
• Electric Power Steering
• Brake booster
• Automatic transmission gear selector
• Horn
• Front wiper
NOTE:
After an accident, remember to cycle the ignition to the STOP
(OFF/LOCK) position and remove the key from the ignition
switch to avoid draining the battery. Carefully check the
vehicle for fuel leaks in the engine compartment and on the
ground near the engine compartment and fuel tank before
resetting the system and starting the engine. If there are no
fuel leaks or damage to the vehicle electrical devices (e.g.
headlights) after an accident, reset the system by following
the procedure described below. If you have any doubt,
contact an authorized dealer.

STARTING AND OPERATING 171
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 conditions, 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 wheeltravel 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 steering 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.
Power Steering Fluid Check
Checking the power steering fluid level at a defined service
interval is not required. The fluid should only be checked if
a leak is suspected, abnormal noises are apparent, and/or
the system is not functioning as anticipated. Coordinate
inspection efforts through your authorized dealer. 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.
WARNING!
Fluid level should be checked on a level surface and with
the engine off to prevent injury from moving parts and
to ensure accurate fluid level reading. Do not overfill.
Use only manufacturer's recommended power steering
fluid.

172 STARTING AND OPERATING
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
SPEED CONTROL — IF EQUIPPED
When engaged, the Speed Control takes over accelerator
operations at speeds greater than 25 mph (40 km/h).
The Speed Control buttons are located on the right side of the
steering wheel.Speed Control Buttons
To Activate
Push the on/off button to activate the Speed Control. The
cruise indicator light in the instrument cluster display will
illuminate. To turn the system off, push the on/off button a
second time. The cruise indicator light will turn off. The
system should be turned off when not in use.
CAUTION!
Do not use chemical flushes in your power steering
system as the chemicals can damage your power steering
components. Such damage is not covered by the New
Vehicle Limited Warranty.
