Switching the Passenger Airbag Off WARNING: If the light does not
illuminate when the passenger airbag
switch is off and you switch the ignition
on, have the passenger airbag switch
serviced immediately by a qualified
technician. WARNING:
To avoid switching on
the airbag, always remove the ignition
key with the switch in the off position. WARNING:
If your vehicle has rear
seats, always transport children who are
12 and younger in the rear seat. Always
use seatbelts and child restraints
properly. Do not place a child in a rear
facing infant seat in the front seat unless
your vehicle is equipped with an airbag
on and off switch and the passenger
airbag is turned off. This is because the
back of the infant seat is too close to the
inflating airbag and the risk of a fatal
injury to the infant when the airbag
inflates is substantial.
The passenger airbag on and off switch is
in the glovebox. 1. Insert the ignition key, turn the switch
to OFF and hold in OFF while removing
the key.
2. When you switch the ignition on, the passenger airbag off light illuminates
briefly, momentarily shuts off and then
switches back on. This indicates that
the passenger airbag is deactivated.
Switching the Passenger Airbag Back
On WARNING:
The seatbelts for the
driver and right front passenger seating
positions are specifically designed to
operate together with the airbags in
certain types of crashes. When you

WARNING: If a supplementary
restraint system component has
deployed, it will not function again. Have
the system and associated components
inspected as soon as possible. Failure to
follow this instruction could result in
personal injury or death.
The side airbags are on the outermost side
of the front seat backrests. In certain
sideways crashes or rollover events, the
side airbags will be inflated. The airbag
was designed to inflate between the door
panel and occupant to further enhance the
protection provided to occupants in side
impact crashes. The system consists of the following:
•
A label or embossed side panel
indicating that your vehicle has side
airbags.
• Side airbags inside the driver and front
passenger seat backrests. Crash sensors and monitoring
system with readiness indicator.
See Crash Sensors and Airbag
Indicator
(page 53). The design and development of the side
airbag system included recommended
testing procedures that were developed
by a group of automotive safety experts
known as the Side Airbag Technical
Working Group. These recommended
testing procedures help reduce the risk of
injuries related to the deployment of side
airbags.
SAFETY CANOPY™
WARNING:
Do not place objects
or mount equipment on or near the
headliner at the siderail that may come
into contact with a deploying curtain
airbag. Failure to follow these
instructions may increase the risk of
personal injury in the event of a crash. WARNING:
Do not lean your head
on the door. The curtain airbag could
injure you as it deploys from the
headliner. WARNING:
Do not attempt to
service, repair, or modify the
supplementary restraint system or
associated components. Failure to
follow this instruction could result in
personal injury or death. WARNING:
All occupants of your
vehicle, including the driver, should
always properly wear their seatbelts,
even when an airbag supplemental
restraint system is provided. Failure to
properly wear your seatbelt could
seriously increase the risk of injury or
death. WARNING:
To reduce risk of injury,
do not obstruct or place objects in the
deployment path of the airbag.

The restraints control module also
monitors the readiness of the above safety
devices plus the crash and occupant
sensors. The readiness of the safety
system is indicated by a warning indicator
light in the instrument cluster or by a
backup tone if the warning light is not
working. Routine maintenance of the
airbag is not required.
A difficulty with the system is indicated by
one or more of the following:
The readiness light will not
illuminate immediately after you
switch the ignition on.
• The readiness light either flashes or
stays lit.
• You hear a series of five beeps. The
tone pattern repeats periodically until
the problem, the light or both are
repaired.
If any of these things happen, even
intermittently, have the supplemental
restraint system serviced at an authorized
dealer immediately. Unless serviced, the
system may not function properly in the
event of a crash.
The fact that the seatbelt pretensioners
or front airbags did not activate for both
front seat occupants in a crash does not
mean that something is wrong with the
system. Rather, it means the restraints
control module determined the accident
conditions (crash severity, belt usage)
were not appropriate to activate these
safety devices.
• The design of the front airbags is to
activate only in frontal and near-frontal
crashes (not rollovers, side impacts or
rear impacts unless the crash causes
sufficient frontal deceleration).
• The design of the seatbelt
pretensioners is to activate in frontal,
near-frontal and side crashes, and in
rollovers. •
The design of the side airbags is to
inflate in certain side impact crashes.
Side airbags may activate in other
types of crashes if the vehicle
experiences sufficient sideways motion
or deformation.
• The design of the Safety Canopy is to
inflate in certain side impact crashes
or rollover events. The Safety Canopy
may activate in other types of crashes
if the vehicle experiences sufficient
sideways motion or deformation, or a
certain likelihood of rollover.
AIRBAG DISPOSAL
Contact your authorized dealer as soon as
possible. Airbags must be disposed of by
qualified personnel.

If you use anything other than our parts for
maintenance replacements or for service
of components affecting emission control,
such aftermarket parts should be
equivalent to our genuine parts in
performance and durability.
Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.
An improperly operating or damaged
exhaust system may allow exhaust to
enter the vehicle. Have a damaged or
improperly operating exhaust system
inspected and repaired immediately.
Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles
are not permitted to intentionally remove
an emission control device or prevent it
from working. Information about your
vehicle
’s emission system is on the Vehicle
Emission Control Information Decal
located on or near the engine. This decal
also lists engine displacement.
Please consult your warranty information
for complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as the
on-board diagnostics system (OBD-II) that
monitors the engine ’s emission control
system. The system protects the
environment by making sure that your
vehicle continues to meet government
emission standards. The OBD-II system
also assists a service technician in properly
servicing your vehicle. When the service engine soon
indicator illuminates, the OBD-II
system has detected a
malfunction. Temporary malfunctions may
cause the service engine soon indicator to
illuminate. Examples are:
1. Your vehicle has run out of fuel —the
engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel —the engine may misfire or run
poorly.
3. The fuel fill inlet may not have closed properly. See Refueling (page 189).
4. Driving through deep water —the
electrical system may be wet.
You can correct these temporary
malfunctions by filling the fuel tank with
good quality fuel, properly closing the fuel
fill inlet or letting the electrical system dry
out. After three driving cycles without these
or any other temporary malfunctions
present, the service engine soon indicator
should stay off the next time you start the
engine. A driving cycle consists of a cold
engine startup followed by mixed city and
highway driving. You do not require
additional vehicle service.
If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may
not have symptoms that are apparent,
continued driving with the service engine
soon indicator on can result in increased
emissions, lower fuel economy, reduced
engine and transmission smoothness and
lead to more costly repairs.

Readiness for Inspection and
Maintenance (I/M) Testing
Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs
to inspect the emission control equipment
on your vehicle. Failure to pass this
inspection could prevent you from getting
a vehicle registration.
If the service engine soon
indicator is on or the bulb does
not work, your vehicle may need
service. See On-Board Diagnostics.
Your vehicle may not pass the I/M test if
the service engine soon indicator is on or
not working properly, for example, the bulb
does not work, or if the OBD-II system has
determined that some of the emission
control systems have not been properly
checked. In this case, the vehicle is not
ready for I/M testing.
If you have just serviced the vehicle ’s
engine or transmission or the battery has
recently run down or you have replaced it,
the OBD-II system may indicate that the
vehicle is not ready for I/M testing. To
determine if the vehicle is ready for I/M
testing, turn the ignition key to the on
position for 15 seconds without cranking
the engine. If the service engine soon
indicator blinks eight times, it means that
the vehicle is not ready for I/M testing; if
the service engine soon indicator stays on
solid, it means that your vehicle is ready
for I/M testing.
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.
If the vehicle is not ready for I/M testing,
you can perform the following driving cycle
consisting of mixed city and highway
driving: 1. 15 minutes of steady driving on an
expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
2. Allow your vehicle to sit for at least eight hours with the ignition off. Then,
start the vehicle and complete the
above driving cycle. The vehicle must
warm up to its normal operating
temperature. Once started, do not turn
off the vehicle until the above driving
cycle is complete.
If the vehicle is still not ready for I/M
testing, you need to repeat the above
driving cycle.
SELECTIVE CATALYTIC
REDUCTANT SYSTEM - DIESEL
Your vehicle may have a selective catalytic
reduction system. The system helps reduce
emission levels of oxides of nitrogen from
the exhaust system. The system
automatically injects diesel exhaust fluid
into the exhaust system to enable correct
selective catalytic reduction system
function.
Note: Selective catalytic reduction systems
are not fitted to vehicles in markets where
only high-sulfur diesel fuel is available.
Diesel Exhaust Fluid Level
In order for the system to operate correctly
you must maintain the diesel exhaust fluid
level.
A warning message appears in the
information display when the diesel
exhaust fluid level is low. If a warning
message appears, refill the diesel exhaust
fluid tank as soon as possible. See
Information Messages (page 121).

USING FOUR-WHEEL DRIVE
Note:
For important information regarding
the safe operation of this type of vehicle,
see General Information in the Wheels and
Tires chapter.
Note: Do not use 4H or 4L mode on dry,
hard surfaced roads. Doing so can produce
excessive noise, increase tire wear and may
damage drive components. 4X4 mode is
only intended for consistently slippery or
loose surfaces. Use of 4L mode on these
surfaces may produce some noise, such as
occasional clunks, but will not damage drive
components.
Note: If 4X4 low is selected while the
vehicle is moving above 3 mph (5 km/h),
the 4WD system will not perform a shift.
This is normal and should be no reason for
concern. Refer to Shifting to or from 4L (4X4
Low) for proper operation.
Note: You can switch on and switch off the
electronic locking differential by pulling the
4WD control (4WD vehicles) or turning the
electronic locking differential control (2WD
vehicles). See
Electronic Locking
Differential (page 221).
Electronic Shift-On-the-Fly
(ESOF) 4WD system
(If Equipped)
Note: If 4X4 Low is selected while the
vehicle is moving above
3 mph (5 km/h),
the 4WD system will not perform a shift.
This is normal and should be no reason for
concern. Refer to Shifting to or from 4L (4X4
Low) for proper system operation.
Note: Auto-manual hub locks can be
manually locked by rotating the hub lock
control from AUTO to LOCK. For proper operation, make sure that each
hub is fully engaged and that both hub
locks are set to the same position (both
set to LOCK or both set to AUTO). To
engage LOCK, turn the hub locks
completely clockwise; to engage AUTO,
turn the hub locks completely
counterclockwise.
The ESOF 4WD system:
•
Provides 4x4 High engagement and
disengagement while the vehicle is
moving.
• Is operated by a rotary control located
on the instrument panel that allows
you select 4x2, 4x4 High or 4x4 Low
operation.
• Uses auto-manual hub locks that can
be engaged and disengaged
automatically based on the 4x4 mode
selected.
• Will increase fuel economy when used
in the hub lock's recommended AUTO
mode.
4WD Indicator Lights
Note: When a 4X4 system fault is present,
the system will typically remain in whichever
4X4 mode was selected prior to the fault
condition occurring. It will not default to 4X2
in all circumstances. When this warning is
displayed, have your vehicle serviced by an
authorized dealer.
