When Should an Airbag Inate?
The driver’s and right front passenger’s frontal
airbags are designed to inate in moderate
to severe frontal or near-frontal crashes. But
they are designed to inate only if the impact
exceeds a predetermined deployment threshold.
Deployment thresholds take into account a
variety of desired deployment and non-deployment
events and are used to predict how severe a
crash is likely to be in time for the airbags to inate
and help restrain the occupants. Whether your
frontal airbags will or should deploy is not based
on how fast your vehicle is traveling. It depends
largely on what you hit, the direction of the impact
and how quickly your vehicle slows down.In addition, your vehicle has “dual stage” frontal
airbags, which adjust the restraint according
to crash severity. For moderate frontal impacts,
these airbags inate at a level less than full
deployment. Your vehicle has electronic frontal
sensors, which help the sensing system distinguish
between a moderate frontal impact and a more
severe frontal impact. For more severe frontal
impacts, full deployment occurs. If the front of
your vehicle goes straight into a wall that does
not move or deform, the threshold level for
the reduced deployment is about 12 to 18 mph
(19 to 29 km/h), and the threshold level for
a full deployment is about 18 to 25 mph
(29 to 40.2 km/h). The threshold level can vary,
however, with specic vehicle design, so that it
can be somewhat above or below this range.

The passenger sensing system will turn off the
right front passenger’s frontal airbag and side
impact airbag (if equipped) under certain
conditions. The driver’s airbags or the second row
side impact airbags (if equipped) are not part of
the passenger sensing system.
The passenger sensing system works with sensors
that are part of the right front passenger’s seat and
safety belt. The sensors are designed to detect the
presence of a properly-seated occupant and
determine if the passenger’s airbag or airbags
should be enabled (may inate) or not.
Accident statistics show that children are safer if
they are restrained in the rear rather than the front
seat. We recommend that child restraints be
secured in a rear seat, including an infant riding in
a rear-facing infant seat, a child riding in a
forward-facing child seat and an older child riding
in a booster seat.Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun
visor says, “Never put a rear-facing child seat
in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.
{CAUTION:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag.
CAUTION: (Continued)

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height,
front end or side sheet metal, they may keep
the airbag system from working properly.
Also, the airbag system may not work properly
if you relocate any of the airbag sensors. If
you have any questions about this, you should
contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in
Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 538.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel,
the instrument panel, or airbag wiring can
affect the operation of the airbag system. If
you have questions, call Customer Assistance.
The phone numbers and addresses for
Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this

SECOND (2):This position reduces vehicle speed
more than DRIVE (D) without using your brakes.
You can use SECOND (2) on hills. It can help
control your speed as you go down steep mountain
roads, but then you would also want to use your
brakes off and on.
Notice:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph
(90 km/h) may damage the transaxle. Also,
shifting into SECOND (2) at speeds above
65 mph (105 km/h) can cause damage. Drive in
THIRD (3) or DRIVE (D) instead of SECOND (2).
Notice:If your vehicle seems to start up
rather slowly, or if it seems not to shift gears
as you go faster, something may be wrong with
a transaxle system sensor. If you drive very
far that way, your vehicle can be damaged.
So, if this happens, have your vehicle serviced
right away. Until then, you can use SECOND (2)
when you are driving less than 35 mph
(55 km/h) and THIRD (3) for higher speeds.FIRST (1):This position reduces vehicle speed
even more than SECOND (2) without using
your brakes. You can use it on very steep hills, or
in deep snow or mud. If the shift lever is put in
FIRST (1) while the vehicle is moving forward, the
transaxle will not shift into rst gear until the
vehicle is going slowly enough.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only the
accelerator pedal may damage the transaxle.
If you are stuck, do not spin the tires. When
stopping on a hill, use the brakes, or parking
brake to hold the vehicle in place.

A light sensor on top of the instrument panel
makes the DRL work, so be sure it is not covered.
The DRL system will make front parking and
turn signal lamps come on in daylight when the
following conditions are met:
The ignition is on.
The exterior lamps control is off.
When the DRL are on, only your front turn signal
lamps will be on. Your instrument panel will
not be lit up.
When it is dark enough outside, the exterior lamps
will come on automatically. When it is bright
enough outside, the exterior lamps will turn off and
the DRL will turn on. Of course, you may still
turn on the headlamps any time you need to.If you start your vehicle in a dark garage, the
automatic headlamp system will come on
immediately. Once you leave the garage, it will
take approximately 30 seconds for the automatic
headlamp system to change to DRL if it is
light outside. During that delay, your instrument
panel cluster may not be as bright as usual. Make
sure your instrument panel brightness control is
in the full bright position. SeeInstrument
Panel Brightness on page 195.
To idle your vehicle with the DRL and automatic
headlamps off, toggle the exterior lamp control
to off after starting the vehicle.
As with any vehicle, you should turn on the
regular headlamp system when you need it.

Overhead Console Switchbank
The overhead console switchbank is located in the
overhead console. This switchbank may include
the following:
Power Sliding Door(s)/Override Switch(es).
SeePower Sliding Door (PSD) on page 121.
Power Rear Quarter Windows. SeePower
Rear Quarter Windows on page 132.
Ultrasonic Rear Parking Assist (URPA)
Disable Switch. SeeUltrasonic Rear Parking
Assist (URPA) on page 200.
If your vehicle does not have some of these
options, there will be a blank.
Ultrasonic Rear Parking
Assist (URPA)
If your vehicle is equipped with the Ultrasonic
Rear Parking Assist (URPA) system, it is designed
to help you park, while the vehicle is in
REVERSE (R). It operates only at very low
speeds, less than 3 mph (5 km/h). URPA can help
make parking easier and to help you avoid
colliding with objects such as parked vehicles. The
URPA system can detect objects up to 5 feet
(1.5 m) behind the vehicle, and tell you how close
these objects are from your rear bumper.
Your vehicle’s URPA operates when the shift lever
is moved into REVERSE (R) and the vehicle
speed is less than 3 mph (5 km/h). Four ultrasonic
sensors located at the rear bumper are used to
detect the distance to the object. The URPA
display is located inside the vehicle, near the rear
window. It has three color-coded lights used to
provide distance and system information to
the driver.

ProCarManuals.com

How the System Works
Unless disabled, the URPA will turn on
automatically when the shift lever is moved into
REVERSE (R). When the system turns on,
the three lights on the display will illuminate for
one and a half seconds to let you know that
the system is working. If your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph
(5 km/h), the red light will ash to remind you that
the system does not work at speed greater
than 3 mph (5 km/h).
If an object is detected at a REVERSE (R) speed
of less than 3 mph (5 km/h), one of the following
will occur:
Description English Metric
amber light 5 ft 1.5 m
amber/amber lights 40 in 1.0 m
amber/amber/red lights &
continuous chime20 in 0.5 m
amber/amber/red lights
ashing & continuous
chime1 ft 0.3 m
A chime will sound the rst time an object is
detected between 20 inches (0.5 m) and 5 feet
(1.5 m) away.URPA cannot detect objects that are above liftgate
level. In order for the rear sensors to recognize
an object, it must be within detection range behind
the vehicle.
When the System Does Not Seem to Work
Properly
The light may ash red when the vehicle is in
REVERSE (R) if the ultrasonic sensors are not kept
clean. So be sure to keep your rear bumper free of
mud, dirt, snow, ice and slush. Other conditions that
may affect system performance include things like
the vibrations from a jackhammer or the
compression of air brakes on a very large truck. If
after cleaning the rear bumper and then driving
forward at least 15 mph (25 km/h), the display
continues to ash red, see your retailer.
If a trailer was attached to your vehicle, or a
bicycle or an object was on the back of, or hanging
out of your liftgate during your last drive cycle,
the light may also ash red. The light will continue
to ash whenever in REVERSE (R) until your
vehicle is driven forward at least 15 mph (25 km/h)
without any obstructions behind the vehicle.

Airbag Readiness Light
There is an airbag readiness light on the
instrument panel, which shows the airbag symbol.
The system checks the airbag’s electrical
system for malfunctions. The light comes on if
there is an electrical problem. The system check
includes the airbag sensor, the airbag modules,
the wiring and the diagnostic module. For
more information on the airbag system, seeAirbag
System on page 83.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should go
out. This means the
system is ready.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
The airbag readiness light should ash for a
few seconds when you turn the ignition key
to RUN. If the light doesn’t come on then, have it
xed so it will be ready to warn you if there is
a problem.
