fuel filler cap may also turn on the Malfunc-
tion Indicator Light (MIL).
• Windshield Washer Fluid Low Indicator
This light will turn on to indicate the
windshield washer fluid is low.
• SERV 4WD
The SERV 4WD light monitors the
electric shift 4WD system. If the
SERV 4WD light stays on or comes
on during driving, it means that the
4WD system is not functioning
properly and that service is required.EVIC Red Telltale LightsThis area will show reconfigurable red telltales.
These telltales include:
• Door Ajar
This light will turn on to indicate
that one or more doors may be
ajar.
• Liftgate Ajar
This light will turn on to indicate
that liftgate may be ajar.
• Liftgate Flipper Glass Ajar
This light will turn on to indicate
that liftgate flipper glass may be

Oil Pressure Warning Light
This light indicates low engine oil pres-
sure. The light should turn on momen-
tarily when the engine is started. If the light turns
on while driving, stop the vehicle and shut off
the engine as soon as possible. A chime will
sound when this light turns on.
• Do not operate the vehicle until the cause is
corrected. This light does not show how
much oil is in the engine. The engine oil level
must be checked under the hood.
• Charging System Light
This light shows the status of the elec-
trical charging system. The light should
come on when the ignition switch is
first turned ON and remain on briefly as a bulb
check. If the light stays on or comes on while
driving, turn off some of the vehicle’s non-
essential electrical devices or increase engine
speed (if at idle). If the charging system light
remains on, it means that the vehicle is experi-
encing a problem with the charging system.

Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer.
•If jump starting is required, refer to “Jump
Starting Procedures” in “What To Do In
Emergencies”.
• Electronic Throttle Control (ETC) Light
This light informs you of a problem
with the Electronic Throttle Control
(ETC) system. The light will come
on when the ignition is first turned
ON and remain on briefly as a bulb
check. If the light does not come on during
starting, have the system checked by an autho-
rized dealer.
• If a problem is detected, the light will come on
while the engine is running. Cycle the ignition
key when the vehicle has completely stopped
and the shift lever is placed in the PARK
position. The light should turn off.
• If the light remains lit with the engine running,
your vehicle will usually be drivable. How-
ever, see an authorized dealer for service as soon as possible. If the light is flashing when
the engine is running, immediate service is
required. You may experience reduced per-
formance, an elevated/rough idle or engine
stall and your vehicle may require towing.
• Engine Temperature Warning Light
This light warns of an overheated en-
gine condition. As temperatures rise
and the gauge approaches H,this in-
dicator will illuminate and a single chime will
sound after reaching a set threshold. Further
overheating will cause the temperature gauge
to pass H,a continuous chime will occur until
the engine is allowed to cool.
• If the light turns on while driving, safely pull
over and stop the vehicle. If the A/C system is
on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the tem-
perature reading does not return to normal,
turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats”
in “What To Do In Emergencies” for more
information. •
Transmission Temperature Light
This light indicates that there is
excessive transmission fluid tem-
perature that might occur with se-
vere usage such as trailer towing. It
may also occur when operating the
vehicle in a high torque converter slip condition,
such as 4-wheel-drive operation (e.g., snow
plowing, off- road operation). If this light comes
on, stop the vehicle and run the engine at idle or
faster, with the transmission in NEUTRAL until
the light goes off.
CAUTION!
Continuous driving with the Transmission
Temperature Indicator illuminated will even-
tually cause severe transmission damage or
transmission failure.
176

REVERSE
This range is for moving the vehicle backward.
Shift into REVERSE only after the vehicle has
come to a complete stop.
NEUTRAL
Use this range when the vehicle is standing for
prolonged periods with the engine running. The
engine may be started in this range. Apply the
parking brake and shift the transmission into
PARK if you must leave the vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off
the ignition to coast down a hill. These are
unsafe practices that limit your response to
changing traffic or road conditions. You might
lose control of the vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for
any other reason with the transmission in
NEUTRAL can cause severe transmission
damage. Refer to “Recreational Towing” in
“Starting And Operating” and “Towing A Dis-
abled Vehicle” in “What To Do In Emergen-
cies” for further information.
DRIVE
This range should be used for most city and
highway driving. It provides the smoothest up-
shifts and downshifts, and the best fuel
economy. The transmission automatically up-
shifts through underdrive first, second, and third
gears, direct fourth gear and overdrive fifth
gear. The DRIVE position provides optimum
driving characteristics under all normal operat-
ing conditions. When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain, travel-
ing into strong head winds, or while towing
heavy trailers), use the AutoStick® shift control
(refer to “AutoStick®” in this section) to select a
lower gear. Under these conditions, using a
lower gear will improve performance and ex-
tend transmission life by reducing excessive
shifting and heat buildup.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition is
detected that could result in transmission dam-
age, Transmission Limp Home Mode is acti-
vated. In this mode, the transmission remains in
direct gear regardless of which forward gear is
selected. PARK, REVERSE, and NEUTRAL will
continue to operate. The Malfunction Indicator
Light (MIL) may be illuminated. Limp Home
Mode allows the vehicle to be driven to an
authorized dealer for service without damaging
the transmission.
229

In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the LOCK/OFF
position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the transmission
will return to normal operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit your authorized
dealer at your earliest possible conve-
nience. Your authorized dealer has diagnos-
tic equipment to determine if the problem
could recur. If the transmission cannot be
reset, authorized dealer service is required.Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control
allows the driver to limit the highest available
gear when the shift lever is in the DRIVE
position. For example, if you shift the transmis-
sion into 3 (third gear), the transmission will
never shift above third gear, but will shift down
into second and first gears normally.
You can switch between DRIVE and ERS mode
at any vehicle speed. When the shift lever is in
the DRIVE position, the transmission will oper-
ate automatically, shifting between all available
gears. Tapping the shift lever to the left (-) will
downshift the transmission, activate ERS mode,
display the current gear in the instrument clus-
ter, and maintain that gear as the top available
gear. Once in ERS mode, tapping the shift lever
to the left (-) or right (+) will change the top
available gears.
To exit ERS mode, simply press and hold the
shift lever to the right (+) until “D” is once again
displayed in the shift lever position indicator in
the instrument cluster.WARNING!
Do not downshift for additional engine brak-
ing on a slippery surface. The drive wheels
could lose their grip and the vehicle could
skid, causing a collision or personal injury.

DRIVE
This range should be used for most city and
highway driving. It provides the smoothest up-
shifts and downshifts, and the best fuel
economy. The transmission automatically up-
shifts through underdrive first and second
gears, direct third gear and overdrive fourth and
fifth gears. The DRIVE position provides opti-
mum driving characteristics under all normal
operating conditions.
To access all six available gears, you must use
the Electronic Range Select (ERS) shift control
(refer to “Electronic Range Select (ERS) Opera-
tion” in this section).
When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain, travel-
ing into strong head winds, or while towing
heavy trailers), use the Electronic Range Select
(ERS) shift control (refer to “Electronic Range
Select (ERS) Operation” in this section) to se-
lect a lower gear range. Under these conditions,
using a lower gear range will improve perfor-
mance and extend transmission life by reducing
excessive shifting and heat buildup.If the transmission temperature exceeds normal
operating limits, the powertrain controller will
modify the transmission shift schedule and ex-
pand the range of torque converter clutch en-
gagement. This is done to prevent transmission
damage due to overheating.
If the transmission becomes extremely hot or is
in danger of overheating, the “Transmission
Temperature Warning Light” may illuminate and
the transmission may operate differently until
the transmission cools down.
NOTE:
Use caution when operating a heavily
loaded vehicle at low speeds (such as tow-
ing a trailer up a steep grade, or in stop-
and-go traffic) during hot weather. In these
conditions, torque converter slip can im-
pose a significant additional heat load on
the cooling system. Downshifting the trans-
mission to the lowest possible gear (when
climbing a grade), or shifting to NEUTRAL
(when stopped in heavy traffic) can help to
reduce this excess heat generation.
During cold temperatures, transmission opera-
tion may be modified depending on engine andtransmission temperature as well as vehicle
speed. This feature improves warm up time of
the engine and transmission to achieve maxi-
mum efficiency. Engagement of both the torque
converter clutch and the top overdrive gear are
inhibited until the transmission fluid is warm
(refer to the “Note” under “Torque Converter
Clutch” in this section). During extremely cold
temperatures (-16°F [-27°C] or below), opera-
tion may briefly be limited to first and direct
gears only. Normal operation will resume once
the transmission temperature has risen to a
suitable level.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition is
detected that could result in transmission dam-
age, Transmission Limp Home Mode is acti-
vated. In this mode, the transmission remains in
direct gear regardless of which forward gear is
selected. PARK, REVERSE, and NEUTRAL will
continue to operate. The Malfunction Indicator
Light (MIL) may be illuminated. Limp Home
Mode allows the vehicle to be driven to an
authorized dealer for service without damaging
the transmission.

In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the LOCK/OFF
position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6.
Shift into the desired gear range. If the prob-
lem is no longer detected, the transmission will
return to normal operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit your authorized
dealer at your earliest possible conve-
nience. Your authorized dealer has diagnos-
tic equipment to determine if the problem
could recur. If the transmission cannot be
reset, authorized dealer service is required. Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control
allows the driver to limit the highest available
gear when the shift lever is in the DRIVE
position. For example, if you shift the transmis-
sion into 3 (third gear), the transmission will
never shift above third gear, but will shift down
into second and first gears normally.
Use of ERS (or TOW/HAUL mode) also enables
an additional underdrive gear which is not nor-
mally used during through-gear accelerations.
This additional gear can improve vehicle perfor-
mance and cooling capability when towing a
trailer on certain grades. In ERS mode, gears 1
though 3 are underdrive gears, and ERS 4 is
direct drive. ERS 5 and 6 (Overdrive gears ) are
the same as the normal fourth and fifth gears.
You can switch between DRIVE and ERS mode at
any vehicle speed. When the shift lever is in the
DRIVE position, the transmission will operate
automatically, shifting between all available
gears. Tapping the shift lever to the left (-) will
activate ERS mode, display the current gear in
the instrument cluster, and maintain that gear as
the top available gear. Once in ERS mode, tap-
ping the shift lever to the left (-) or right (+) will
change the top available gear.
The instrument cluster display will show the
requested top gear limit, however the transmis-
sion will not downshift to the requested gear if
doing so would overspeed the engine. The
transmission will downshift once the vehicle
speed has slowed sufficiently.
To exit ERS mode, simply press and hold the
shift lever to the right (+) until “D” is once again
displayed in the shift lever position indicator in
the instrument cluster.
WARNING!
Do not downshift for additional engine brak-
ing on a slippery surface. The drive wheels
could lose their grip and the vehicle could
skid, causing a collision or personal injury.
NOTE:
To select the proper gear position for maxi-
mum deceleration (engine braking), simply
press and hold the shift lever to the left (-).
The transmission will shift to the range from
which the vehicle can best be slowed down.
235

The system requires that the engine be running
for all changes. When lowering the vehicle all of
the doors, including the liftgate, must be closed.
If a door is opened at any time while the vehicle
is lowering the change will not be completed
until the open door(s) is closed.
The Quadra-Lift™ air suspension system uses
a lifting and lowering pattern which keeps the
headlights from incorrectly shining into oncom-
ing traffic. When raising the vehicle, the rear of
the vehicle will move up first and then the front.
When lowering the vehicle, the front will move
down first and then the rear.
After the engine is turned off, it may be noticed
that the air suspension system operates briefly,
this is normal. The system is correcting the
position of the vehicle to ensure a proper ap-
pearance.
To assist with changing a spare tire, the
Quadra-Lift™ air suspension system has a fea-
ture which allows the automatic leveling to be
disabled. Press and hold both the “Up” and
“Down” buttons simultaneously between 5 and
10 seconds, a message will appear in the EVIC
stating leveling has been disabled immediatelyafter both buttons have been released. Refer to
“Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for
further information. Driving the vehicle over
5 mph (8 km/h) will return the air suspension to
normal operation. Refer to “Jacking and Tire
Changing” in “What To Do In Emergencies” for
further information.
WARNING!
The air suspension system uses a high pres-
sure volume of air to operate the system. To
avoid personal injury or damage to the sys-
tem, see your authorized dealer for service.
Electronic Vehicle Information
Center (EVIC) Display Messages
When the appropriate conditions exist, a mes-
sage will appear in the EVIC display. Refer to
“Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for
further information.
An audible chime will be heard whenever a
system error has been detected.
OperationThe indicator lamps 3 through 6 will illuminate to
show the current position of the vehicle. Flash-
ing indicator lamps will show a position which
the system is working to achieve. When raising,
if multiple indicator lamps are flashing on the
“Up” button, the highest flashing indicator lamp
is the position the system is working to achieve.
When lowering, if multiple indicators are flash-
ing on the
"Up"button the lowest solid indicator
lamp is the position the system is working to
achieve.
Pressing the “UP” button once will move the
suspension one position higher from the current
position, assuming all conditions are met (i.e.
engine running, speed below threshold, etc).
The “UP” button can be pressed multiple times,
each press will raise the requested level by one
position up to a maximum position of OR2 or the
highest position allowed based on current con-
ditions (i.e. vehicle speed, etc).

Life Of TireThe service life of a tire is dependent upon
varying factors including, but not limited to:
•Driving style
• Tire pressure
• Distance driven
• Performance tires, tires with a speed rating of
V or higher, and summer tires typically have
a reduced tread life. Rotation of these tires
per the vehicle maintenance schedule is
highly recommended.
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can
result in sudden tire failure. You could lose
control and have a collision resulting in seri-
ous injury or death.
Keep dismounted tires in a cool, dry place with
as little exposure to light as possible. Protect
tires from contact with oil, grease, and gasoline.
Replacement TiresThe tires on your new vehicle provide a balance
of many characteristics. They should be in-
spected regularly for wear and correct cold tire
inflation pressure. The manufacturer strongly
recommends that you use tires equivalent to the
originals in size, quality and performance when
replacement is needed. Refer to the paragraph
on “Tread Wear Indicators”. Refer to the “Tire
and Loading Information” placard for the size
designation of your tire. The Load Index and
Speed Symbol for your tire will be found on the
original equipment tire sidewall. See the Tire
Sizing Chart example found in the Tire Safety
Information section of this manual for more
information relating to the Load Index and
Speed Symbol of a tire.
It is recommended to replace the two front tires
or two rear tires as a pair. Replacing just one tire
can seriously affect your vehicle’s handling. If
you ever replace a wheel, make sure that the
wheel’s specifications match those of the origi-
nal wheels. It is recommended you contact your authorized
tire or original equipment vehicle dealer with
any questions you may have on tire specifica-
tions or capability. Failure to use equivalent
replacement tires may adversely affect the
safety, handling, and ride of your vehicle.
WARNING!
•
Do not use a tire, wheel size or rating other
than that specified for your vehicle. Some
combinations of unapproved tires and
wheels may change suspension dimen-
sions and performance characteristics, re-
sulting in changes to steering, handling,
and braking of your vehicle. This can
cause unpredictable handling and stress
to steering and suspension components.
You could lose control and have a collision
resulting in serious injury or death. Use
only the tire and wheel sizes with load
ratings approved for your vehicle.
