WARNING!
²Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won't deploy at all.
Always wear your seat belts even though you
have airbags.
²Being too close to the steering wheel or instru-
ment panel during airbag deployment could cause
serious injury. Airbags need room to inflate. Sit
back, comfortably extending your arms to reach
the steering wheel or instrument panel.
²The left and right side curtain airbags need room
to inflate. Do not lean against the door or window.
Sit upright in the center of the seat.

Rain Sensing WipersÐIf Equipped
This feature senses moisture on the windshield and
automatically activates the wipers for the driver. The
feature is especially useful for road splash or overspray
from the windshield washers of the vehicle ahead. Rotate
the end of the multi-function lever to one of five settings
to activate this feature.The sensitivity of the system can be adjusted with the
multi-function lever. Wiper delay position 1 is the least
sensitive, and wiper delay position 5 is the most sensi-
tive. Setting 3 should be used for normal rain conditions.
Settings 1 and 2 can be used if the driver desires less
wiper sensitivity. Settings 4 and 5 can be used if the
driver desires more sensitivity. Place the wiper switch in
the OFF position when not using the system.
NOTE:
²The rain sensing feature will not operate when the
wiper switch is in the LOW or HIGH speed position.
²The rain sensing feature may not function properly
when ice, or dried salt water is present on the wind-
shield.
²Use of Rain-Xtor products containing wax or silicone
may reduce rain sensor performance.

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 roll overs, especially those
that involve leaving the roadway or striking objects
or other vehicles. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of an
ERM-equipped vehicle must never be exploited in a
reckless or dangerous manner which could jeopar-
dize the user's safety or the safety of others.
ESP (Electronic Stability Program)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESP cor-
rects for over/under steering of the vehicle by applyingthe brake of the appropriate wheel to assist in counter-
acting the over/under steer condition. Engine power
may also be reduced to help the vehicle maintain the
desired path.
ESP 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, ESP applies the brake of the appropri-
ate wheel to assist in counteracting the oversteer or
understeer condition.
²Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
²Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.

Rear Park Assist Sensors
The four Rear Park Assist Sensors, located in the rear
fascia, monitor the area behind the vehicle that is within
the sensors' field of view. The monitored area seems oval
in shape.
The sensors can detect obstacles from approximately 11.8
inches (30 cm) up to 59 inches (150 cm) from the rear
fascia in the horizontal direction, depending on the
location and orientation of the obstacle and the type of
obstacle.
Rear Park Assist Warning Display
The Rear Park Assist Warning Display, located in the
headliner near the flipper glass, provides both visual and
audible warnings to indicate the distance between the
rear fascia and the detected obstacle.Rear Park Assist Display

Service the Rear Park Assist System
When the Rear Park Assist System is defective, the
instrument cluster will actuate a single chime, once per
ignition cycle, and it will display the9SERVICE PARK
ASSIST SYSTEM9message. Refer to ªElectronic Vehicle
Information Center (EVIC)º in Section 4 of this manual.
Cleaning the Rear Park Assist System
Clean the Rear Park Assist Sensors with water, car wash
soap and a soft cloth. Do not use rough or hard cloths. Do
not scratch or poke the sensors. Otherwise, you could
damage the sensors.
CAUTION!
²The Rear Park Assist System is only a parking aid
and it is unable to recognize every obstacle, in-
cluding small obstacles. Parking curbs might be
temporarily detected or not detected at all. Ob-
stacles located above or below the sensors will not
be detected when they are in close proximity.
²The vehicle must be driven slowly when using the
Rear Park Assist System to be able to stop in time
when the obstacle is detected. It is recommended
that the driver looks over his/her shoulder when
using the Rear Park Assist System.

WARNING!
²Drivers must be careful when backing up even when
using the Rear Park Assist System. Always check
carefully behind your vehicle, look behind you, and
be sure to check for pedestrians, animals, other
vehicles, obstructions, and blind spots before back-
ing up. You are responsible for safety and must
continue to pay attention to your surroundings. Fail-
ure to do so can result in serious injury or death.
²Before using the Rear Park Assist System, it is
strongly recommended that the ball mount and hitch
ball assembly is disconnected from the vehicle when
the vehicle is not used for towing. Failure to do so
can result in injury or damage to vehicles or ob-
stacles because the hitch ball will be much closer to
the obstacle than the rear fascia when the warning
display turns the red LEDs ON. Also, the sensors
could detect the ball mount and hitch ball assembly,
depending on its size and shape, giving a false
indication that an obstacle is behind the vehicle.
NOTE:Clean all four Rear Park Assist Sensors regularly,
taking care not to scratch or damage them. The sensors
must not be covered with ice, snow, slush, mud, dirt or
debris. Failure to do so can result in the system not
working properly. The system might not detect an ob-
stacle behind the fascia or it could provide a false
indication that an obstacle is behind the fascia.
Assure objects are not within 11.8 inches (30 cm) from the
rear fascia while driving the vehicle. Failure to do so can
result in the system misinterpreting a close object as a
sensor problem, causing the9SERVICE PARK ASSIST
SYSTEM9message to be displayed in the instrument
cluster.
Ultrasonic noise from airbrakes of nearby trucks, air
powered jackhammers and air powered shop tools, to
name a few, will cause the Rear Park Assist System to be
disabled until the ultrasonic noise is no longer present.

CLIMATE CONTROLS
Automatic Temperature Control
The Infrared Dual-Zone Climate Control System auto-
matically maintains the interior comfort level desired by
the driver and passenger. This is accomplished by a dual
sun-sensor in the top of the instrument panel, and an
infrared sensor located in the face of the control unit.
There are also various sensors monitored by this system
which take account for vehicle speed, A/C pressure,
outside temperature, and engine cooling temperature.
The infrared sensor independently measures the surface
temperature of the driver and passenger. Based on the
sensor input, the system automatically adjusts the air
flow temperature, the air flow volume, and amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.NOTE:The numbers on the temperature dial represent
a comfort setting when the Mode knob is set to Auto, and
not the actual air temperature.
Operation of the system is quite simple. Begin by turning
the right mode knob to AUTO, and place the blower
control (left knob) to either LO AUTO or HI AUTO. The
