EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the
vehicle from the engine and exhaust
system heat and noise. On vehicles with
no original equipment floor covering
insulation, do not carry passengers in a
manner that permits prolonged skin
contact with the metal floor. Failure to
follow these instructions may result in
fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws. Tampering with emissions
control systems including
related sensors or the Diesel
Exhaust Fluid system can result in reduced
engine power and the illumination of the
service engine soon light. Tampering With a Noise Control
System
Federal laws prohibit the following acts:
•
Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design.
The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.

Note:
The information display may show
messages during 4WD operation. See
Information Messages (page 123).
Your 4X4 control is located in one of the
following locations:
• On the instrument panel.
• On the
DRIVE MODE selection switch.
2H - 4X2
Delivers power to the rear wheels only. The
information display momentarily shows
2H when this mode is selected. This mode
is appropriate for normal on-road driving
on dry pavement and provides the best
fuel economy.
Note: 2H may turn on or off automatically
based on Drive Mode selection. See
Drive
Control (page 261).
4A - 4X4 AUTO
Provides electronic controlled four-wheel
drive with power delivered to the front and
rear wheels, as required, for increased
traction. When you select this mode, the
information display shows 4A. The system
continuously monitors road conditions,
driver input as well as other vehicle sensors
and optimizes the system's behavior based
on drive mode selection.
Note: On vehicles with a rotary drive mode
switch, 4A should remain on in Mud/Rut and
Sand but with aggressive tuning which
provides electronically locked four-wheel
drive power to front and rear wheels, the
same as traditional 4H.
Note: 4A may turn on or off automatically
based on Drive Mode selection. See
Drive
Control (page 261). 4H - 4X4 HIGH
Provides electronically locked four-wheel
drive power to front and rear wheels. When
you select this mode, the information
display shows 4H. This mode is not
recommended for use on dry pavement.
This mode is only intended for severe
winter or off-road conditions, such as deep
snow, ice or shallow sand.
Note:
4H may turn on or off automatically
based on Drive Mode selection. In
configurations with a rotary Drive Mode
switch, 4H functionality is within the
Mud/Ruts and Sand Drive Modes even when
the indicator lamp shows 4A. See
Drive
Control (page 261).
4L - 4X4 LOW
Provides electronically locked four-wheel
drive power to both the front and rear
wheels with additional gearing for
increased torque multiplication. Intended
only for off-road applications such as deep
sand, steep grades, or pulling heavy
objects. 4L - 4X4 low does not engage
when your vehicle is moving above
3 mph
(5 km/h); this is normal and should be no
reason for concern. Refer to Shifting to or
from 4L - 4X4 low for proper operation.
Note: 4L may turn off automatically based
on Drive Mode selection. See
Drive Control
(page 261).
Shifting Between 4WD System Modes
Note: Momentarily releasing the accelerator
pedal when a shift in progress message
displays improves engagement and
disengagement performance.
Note: Do not perform this operation if the
rear wheels are slipping.
Note: Some noise may be heard as the
system shifts or engages; this is normal.

(If Equipped)

when the engine has sufficient torque to
prevent your vehicle from rolling down the
grade. This is an advantage when pulling
away on a slope, for example from a car
park ramp, traffic lights or when reversing
uphill into a parking space.
The system will activate automatically on
any slope that will cause significant vehicle
rollback. For vehicles with a manual
transmission, you can switch this feature
off using the information display. See
Information Displays (page 111). The
system will remain on or off depending on
how it was last set.
Note: There is no warning lamp to indicate
the system is either on or off.
Note: If your vehicle is equipped with Auto
Hold, Hill Start Assist will not be available
while Auto Hold is active.
Using Hill Start Assist
1. Bring your vehicle to a complete standstill. Keep the brake pedal
pressed and select an uphill gear (for
example, drive (D) or first (1) when
facing uphill or reverse (R) when facing
downhill).
2. If the sensors detect that your vehicle is on a slope, the system will activate
automatically.
3. When you remove your foot from the brake pedal, your vehicle will remain
on the slope without rolling away for
about two or three seconds. This hold
time will automatically be extended if
you are in the process of driving off.
4. Drive off in the normal manner. The brakes will release automatically. Switching the System On and Off
You can switch this feature on or off if your
vehicle is equipped with a manual
transmission and an information display.
See
General Information (page 111). The
system remembers the last setting when
you start your vehicle.
If your vehicle is not equipped with a
manual transmission and an information
display, you cannot turn the system on or
off. When you switch the ignition on, the
system automatically turns on.

PRINCIPLE OF OPERATION
WARNING: Vehicle modifications
involving braking system, aftermarket
roof racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic
stability control system. In addition,
installing any stereo loudspeakers may
interfere with and adversely affect the
electronic stability control system. Install
any aftermarket stereo loudspeaker as
far as possible from the front center
console, the tunnel, and the front seats
in order to minimize the risk of interfering
with the electronic stability control
sensors. Reducing the effectiveness of
the electronic stability control system
could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. WARNING:
Remember that even
advanced technology cannot defy the
laws of physics. It’ s always possible to
lose control of a vehicle due to
inappropriate driver input for the
conditions. Aggressive driving on any
road condition can cause you to lose
control of your vehicle increasing the risk
of personal injury or property damage.
Activation of the electronic stability
control system is an indication that at
least some of the tires have exceeded
their ability to grip the road; this could
reduce the operator ’s ability to control
the vehicle potentially resulting in a loss
of vehicle control, vehicle rollover,
personal injury and death. If your
electronic stability control system
activates, SLOW DOWN.
The system automatically turns on each
time you switch the ignition on. If a fault occurs in either the stability
control or the traction control system, you
may experience the following conditions:
•
The stability and traction control light
illuminates steadily.
• The stability control and traction
control systems do not enhance your
vehicle's ability to maintain traction of
the wheels.
If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake, the brake
pedal may move as the system applies
higher brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.
Roll Stability Control
The system enhances your vehicle ’s ability
to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which
it changes by applying the brakes to one
or more wheels individually.
