2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 13

NOTE: The Driver and Passenger Advanced Front Air
Bags are certified to new Federal regulations.
The Advanced Front Air Bags have a multistage inflator
design. This allows the air bag to have different rates of
inflation that are based on several factors, including the
severity and type of collision.
This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Air Bags based upon
seat position.
This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether
the driver or front passenger seat belt is fastened. The
seat belt buckle switch may adjust the inflation rate of the
Advanced Front Air Bags. This vehicle may be equipped with Supplemental Seat-
Mounted Side Air Bags (SAB). The SABs are marked with
an air bag label sewn into the outboard side of the front
seats.
NOTE:
• Air Bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
• After any collision, the vehicle should be taken to an
authorized dealer immediately.

Air Bag System Components
Your vehicle may be equipped with the following air bag
system components:
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
• Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolster
• Driver Advanced Front Air Bag
• Passenger Advanced Front Air Bag
• Supplemental Seat-Mounted Side Air Bags (SAB)
• Front and Side Impact Sensors
• Front Seat Belt Pretensioners, Seat Belt Buckle Switch,
and Seat Track Position Sensors Advanced Front Air Bag Features
The Advanced Front Air Bag system has multistage
driver and front passenger air bags. This system provides
output appropriate to the severity and type of collision as
determined by the Occupant Restraint Controller (ORC),
which may receive information from the front impact
sensors.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. This low output
is used in less severe collisions. A higher energy output is
used for more severe collisions.
WARNING!• No objects should be placed over or near the air bag
on the instrument panel, because any such objects
could cause harm if the vehicle is in a collision
severe enough to cause the air bag to inflate. (Continued)64 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Along with seat belts and pretensioners, Advanced Front
Air Bags work with the Supplemental Driver Side Knee
Air Bag and the passenger side knee bolster to provide
improved protection for the driver and front passenger.
Side air bags also work with seat belts to improve
occupant protection.
Air Bag Deployment Sensors And Controls
Occupant Restraint Controller (ORC)
The ORC is part of a Federally regulated safety system
required for this vehicle.
The ORC determines if deployment of the front and/or
side air bags is required in a frontal or side collision.
Based on the impact sensor’s signals, a central electronic
ORC deploys the Advanced Front Air Bags, Supplemen-
tal Seat-Mounted Side Air Bags (SAB) — if equipped, and
front seat belt pretensioners, as required, depending on
the severity and type of impact. Advanced Front Air Bags are designed to provide addi-
tional protection by supplementing the seat belts in
certain frontal collisions depending on the severity and
type of collision. Advanced Front Air Bags are not
expected to reduce the risk of injury in rear, side, or
rollover collisions.
The Advanced Front Air Bags will not deploy in all
frontal collisions, including some that may produce
substantial vehicle damage — for example, some pole
collisions, truck underrides, and angle offset collisions.
On the other hand, depending on the type and location of
impact, Advanced Front Air Bags may deploy in crashes
with little vehicle front-end damage but that produce a
severe initial deceleration.
2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 67

The side air bags will not deploy in all side collisions.
Side air bag deployment will depend on the severity and
type of collision.
Because air bag sensors measure vehicle deceleration
over time, vehicle speed and damage by themselves are
not good indicators of whether or not an air bag should
have deployed.
Seat belts are necessary for your protection in all crashes,
and also are needed to help keep you in position, away
from an inflating air bag.
The ORC also monitors the readiness of the electronic
parts of the air bag system whenever the ignition switch
is in the START or ON/RUN positions. If the key is in the
LOCK position, in the ACC position, or not in the
ignition, the air bag system is not on and the air bags will
not inflate. The ORC contains a backup power supply system that
may deploy the air bags even if the battery loses power or
it becomes disconnected prior to deployment.
Also, the ORC turns on the Air Bag Warning
Light for four to eight seconds for a self-check
when the ignition is first turned on. After the
self-check, the Air Bag Warning Light will turn
off. If the ORC detects a malfunction in any part of the
system, it turns on the Air Bag Warning Light either
momentarily or continuously. A single chime will sound
if the light comes on again after initial startup.
It also includes diagnostics that will illuminate the instru-
ment cluster Air Bag Warning Light if a malfunction is
noted that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction.68 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Supplemental Seat-Mounted Side Air Bags (SAB)
Inflator Units — If Equipped
The Supplemental Seat-Mounted Side Air Bags Inflator
Units (if equipped) are designed to activate only in
certain side collisions.
The ORC determines if a side collision requires the side
air bags to inflate, based on several factors, including the
severity and type of collision.
Based on several factors, including the severity and type
of collision, the side air bag inflator on the crash side of
the vehicle is triggered releasing a quantity of non-toxic
gas. The inflating SAB exits through the seat seam into
the space between the occupant and the door. The SAB
fully inflate in about 10 milliseconds. The side air bag
moves at a very high speed and with such a high force
that it could injure you if you are not seated properly, or
if items are positioned in the area where the side air bag
inflates. This especially applies to children. Front And Side Impact Sensors
In front and side impacts, impact sensors can aid the ORC
in determining appropriate response to impact events.
Enhanced Accident Response System
In the event of an impact causing air bag deployment, 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 follow-
ing functions:
• Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power or
until the ignition key is turned off.70 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
CAUTION!The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result. 24. Odometer / Trip Odometer Display Area
The odometer display shows the total distance the vehicle
has been driven. The trip odometer shows individual trip
mileage. Refer to “Odometer/Trip Odometer/ECO (Fuel
Saver Indicator) Button” for additional information.
U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. If your
odometer needs to be repaired or serviced, the repair
technician should leave the odometer reading the same
as it was before the repair or service. If s/he cannot do so,
then the odometer must be set at zero, and a sticker must
be placed in the door jamb stating what the mileage was
before the repair or service. It is a good idea for you to
make a record of the odometer reading before the repair/
service, so that you can be sure that it is properly reset, or
that the door jamb sticker is accurate if the odometer
must be reset at zero.308 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE:
• A good calibration requires a level surface and an envi-
ronment free from large metallic objects such as build-
ings, bridges, underground cables, railroad tracks, etc.
• Magnetic materials should be kept away from the top
of the center of the instrument panel. This is where the
compass sensor is located.
Average Fuel Economy/Distance To Empty (DTE)/
Elapsed Time
• Average Fuel Economy
Shows the average fuel economy since the last reset.
When the fuel economy is reset, the digits will go blank
while the history information is erased. The averaging
will restart when enough new distance and fuel data is
accumulated. • Distance To Empty (DTE)
Shows the estimated distance that can be traveled with
the fuel remaining in the tank. This estimated distance is
determined by a weighted average of the instantaneous
and average fuel economy, according to the current fuel
tank level. DTE cannot be reset.
• Elapsed Time
Shows the total elapsed time of travel since the last reset.
Elapsed time will increment when the ignition switch is
in the RUN or START positions. The elapsed timer
displays minutes:seconds. After 59minutes:59seconds, it
displays hours:minutes:seconds.

Manual Compass Calibration
If the compass appears erratic and the “CAL” indicator
does not appear in the EVIC display, you must put the
compass into the Calibration Mode manually as follows:
1. Start the engine. Leave the shift lever in PARK in order
to enter the EVIC Programming Menus.
2. Press the MENU button until Personal Settings
(Customer-Programmable Features) displays in the
EVIC.
3. Press the DOWN button until “Calibrate Compass”
displays in the EVIC.
4. Press and release the SELECT button to start the
calibration. The “CAL” indicator will display in the
EVIC. 5. Complete one or more 360–degree turns (in an area
free from large metal or metallic objects) until the
“CAL” indicator turns off. The compass will now
function normally.
Compass Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To compensate for the
differences, the variance should be set for the zone where
the vehicle is driven, per the zone map. Once properly
set, the compass will automatically compensate for the
differences and provide the most accurate compass head-
ing.
NOTE: Magnetic materials should be kept away from
the top of the instrument panel; this is where the compass
sensor is located.328 UNDERSTANDING YOUR INSTRUMENT PANEL

WARNING! (Continued)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.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESC
corrects for over/under steering of the vehicle by apply-
ing 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 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 the intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
• Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster), starts to flash as soon as
the tires lose traction and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator Light” also
flashes when TCS is active. If the “ESC Activation/
Malfunction Indicator Light” begins to flash during ac-
celeration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
