STARTING PROCEDURESBefore starting your vehicle, adjust your seat,
adjust the inside and outside mirrors, fasten
your seat belt, and if present, instruct all other
occupants to buckle their seat belts.
WARNING!
Never leave children alone in a vehicle. Leav-
ing unattended children in a vehicle is danger-
ous for a number of reasons. A child or others
could be seriously or fatally injured. Do not
leave the key fob in the ignition switch. A child
could operate power windows, other controls,
or move the vehicle.
Automatic TransmissionThe shift lever must be in the NEUTRAL or
PARK position before you can start the engine.
Apply the brakes before shifting into any driv-
ing gear.
CAUTION!
Damage to the transmission may occur if the
following precautions are not observed:
•Shift into PARK only after the vehicle has
come to a complete stop.
• Shift into or out of REVERSE only after the
vehicle has come to a complete stop and
the engine is at idle speed.
• Do not shift from REVERSE, PARK, or
NEUTRAL into any forward gear when the
engine is above idle speed.
• Before shifting into any gear, make sure
your foot is firmly on the brake pedal.
Using Fob With Integrated Key (Tip Start)
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or
pressing the accelerator pedal.
Do not press the accelerator. Use the Fob with
Integrated Key to briefly turn the ignition switch
to the START position and release it as soon as
the starter engages. The starter motor will con-
tinue to run, and it will disengage automatically when the engine is running. If the engine fails to
start, the starter will disengage automatically in
10 seconds. If this occurs, turn the ignition
switch to the LOCK position, wait 10 to 15 sec-
onds, then repeat the “Normal Starting” proce-
dure.
Keyless Enter-N-Go
This feature allows the
driver to operate the ig-
nition switch with the
push of a button, as long
as the ENGINE START/
STOP button is installed
and the Remote Keyless
Entry (RKE) transmitter
is in the passenger com-
partment.
Installing and Removing the ENGINE
START/STOP Button
Installing the Button
1. Remove the key fob from the ignition switch.
2. Insert the ENGINE START/STOP button into
the ignition switch with the lettering facing up
and readable.
200
3. Press firmly on the center of the button to
secure it into position.
Removing the Button
1. The ENGINE START/STOP button can be
removed from the ignition switch for key fob
use.
2. Insert the metal part of the emergency key
under the chrome bezel at the 6 o’clock posi-
tion and gently pry the button loose.
NOTE:
The ENGINE START/STOP button should
only be removed or inserted with the ignition
in the LOCK position (OFF position for Key-
less Enter-N-Go).
Normal Starting
Using the ENGINE START/STOP Button
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or
pressing the accelerator pedal.
To start the engine, the transmission must be in
PARK or NEUTRAL. Press and hold the brakepedal while pressing the ENGINE START/STOP
button once. The system takes over and at-
tempts to start the vehicle. If the vehicle fails to
start, the starter will disengage automatically
after 10 seconds. If you wish to stop the crank-
ing of the engine prior to the engine starting,
press the button again.
To Turn Off the Engine Using ENGINE
START/STOP Button
1. Place the shift lever in PARK, then press and
release the ENGINE START/STOP button.
2. The ignition switch will return to the OFF
position.
3. If the shift lever is not in PARK, the ENGINE
START/STOP button must be held for two sec-
onds and vehicle speed must be above 5 mph
(8 km/h) before the engine will shut off. The
ignition switch position will remain in the ACC
position until the shift lever is in PARK and the
button is pressed twice to the OFF position. If
the shift lever is not in PARK and the ENGINE
START/STOP button is pressed once, the EVIC
(if equipped) will display a “Vehicle Not In Park”
message and the engine will remain running.
Never leave a vehicle out of the PARK position,
or it could roll.
NOTE:
If the ignition switch is left in the ACC or
RUN (engine not running) position and the
transmission is in PARK, the system will
automatically time out after 30 minutes of
inactivity and the ignition will switch to the
OFF position.
Keyless Enter-N-Go Functions – With
Driver’s Foot OFF the Brake Pedal (In
PARK or NEUTRAL Position)
The Keyless Enter-N-Go feature operates simi-
lar to an ignition switch. It has four positions,
OFF, ACC, RUN and START. To change the
ignition switch positions without starting the
vehicle and use the accessories follow these
steps.
•
Starting with the ignition switch in the OFF
position:
• Press the ENGINE START/STOP button once
to change the ignition switch to the ACC
position (EVIC displays “IGNITION MODE
ACCESSORY”),
201
•Press the ENGINE START/STOP button a
second time to change the ignition switch to
the RUN position (EVIC displays “IGNITION
MODE RUN”),
• Press the ENGINE START/STOP button a
third time to return the ignition switch to the
OFF position (EVIC displays “IGNITION
MODE OFF”).
Extreme Cold Weather
(Below 20°F or 29°C)
To ensure reliable starting at these tempera-
tures, use of an externally powered electric
engine block heater (available from your autho-
rized dealer) is recommended.
If Engine Fails To Start
WARNING!
• Never pour fuel or other flammable liquids
into the throttle body air inlet opening in an
attempt to start the vehicle. This could
result in a flash fire causing serious per-
sonal injury.
(Continued)
WARNING!(Continued)
• Do not attempt to push or tow your vehicle
to get it started. Vehicles equipped with an
automatic transmission cannot be started
this way. Unburned fuel could enter the
catalytic converter and once the engine has
started, ignite and damage the converter
and vehicle. If the vehicle has a discharged
battery, booster cables may be used to
obtain a start from a booster battery or the
battery in another vehicle. This type of start
can be dangerous if done improperly. Refer
to “Jump Starting” in “What To Do In Emer-
gencies” for further information.
Clearing a Flooded Engine
(Using ENGINE START/STOP Button)
If the engine fails to start after you have fol-
lowed the “Normal Starting” or “Extreme Cold
Weather procedures, it may be flooded. To
clear any excess fuel, press and hold the brake
pedal, push the accelerator pedal all the way to
the floor and hold it, then press and release the
ENGINE START/STOP button once. The starter
motor will engage automatically, run for 10 sec- onds, and then disengage. Once this occurs,
release the accelerator pedal and the brake
pedal, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.
Clearing A Flooded Engine
(Using Fob With Integrated Key)
If the engine fails to start after you have fol-
lowed the “Normal Starting” or “Extreme Cold
Weather” procedures, it may be flooded. To
clear any excess fuel, push the accelerator
pedal all the way to the floor and hold it. Then,
turn the ignition switch to the START position
and release it as soon as the starter engages.
The starter motor will disengage automatically
in 10 seconds. Once this occurs, release the
accelerator pedal, turn the ignition switch to the
LOCK position, wait 10 to 15 seconds, then
repeat the “Normal Starting” procedure.
CAUTION!
To prevent damage to the starter, wait 10 to
15 seconds before trying again.
After StartingThe idle speed is controlled automatically and it
will decrease as the engine warms up.
202
starter will disengage automatically in 20 sec-
onds. The starter can be disengaged by turn-
ing the ignition switch to the OFF position, if
required.
5. After the engine starts, allow it to idle for
approximately 30 seconds before driving. This
allows oil to circulate and lubricate the turbo-
charger.
Avoid prolonged idling in ambient tempera-
tures below 0°F (-18°C). Long periods of idling
may be harmful to your engine because com-
bustion chamber temperatures can drop so low
that the fuel may not burn completely. Incom-
plete combustion allows carbon and varnish to
form on piston rings and injector nozzles. Also,
the unburned fuel can enter the crankcase,
diluting the oil and causing rapid wear to the
engine.
Engine Warm Up
Avoid full throttle operation when the engine is
cold. When starting a cold engine, bring the
engine up to operating speed slowly to allow
the oil pressure to stabilize as the engine
warms up.NOTE:
High-speed, no-load running of a cold en-
gine can result in excessive white smoke
and poor engine performance. No-load en-
gine speeds should be kept under 1,200
RPM during the warm-up period, especially
in cold ambient temperature conditions.
If temperatures are below 32°F (0°C), operate
the engine at moderate speeds for five minutes
before full loads are applied.
Engine Idling – In Cold Weather
Avoid prolonged idling in ambient tempera-
tures below 0°F (-18°C). Long periods of idling
may be harmful to your engine because com-
bustion chamber temperatures can drop so low
that the fuel may not burn completely. Incom-
plete combustion allows carbon and varnish to
form on piston rings and injector nozzles. Also,
the unburned fuel can enter the crankcase,
diluting the oil and causing rapid wear to the
engine.
Stopping The Engine
Before turning off your turbo diesel engine,
always allow the engine to return to normal idle
speed and run for several seconds. This as-sures proper lubrication of the turbocharger.
This is particularly necessary after any period
of hard driving.
Idle the engine a few minutes before routine
shutdown. After full load operation, idle the
engine three to five minutes before shutting it
down. This idle period will allow the lubricating
oil and coolant to carry excess heat away from
the combustion chamber, bearings, internal
components, and turbocharger. This is espe-
cially important for turbocharged, charge air
cooled engines.
AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the
following precautions are not observed:
•
Shift into PARK only after the vehicle has
come to a complete stop.
• Shift into or out of REVERSE only after the
vehicle has come to a complete stop and
the engine is at idle speed.
(Continued)
204
Five-Speed Automatic TransmissionThe electronically-controlled transmission pro-
vides a precise shift schedule. The transmis-
sion electronics are self-calibrating; therefore,
the first few shifts on a new vehicle may be
somewhat abrupt. This is a normal condition,
and precision shifts will develop within a few
hundred miles/kilometers.
Gear Ranges
NOTE:
After selecting any gear range, wait a mo-
ment to allow the selected gear to engage
before accelerating. This is especially im-
portant when the engine is cold. If there is a
need to restart the engine, be sure to turn
the ignition switch to the LOCK position
before restarting. Transmission gear en-
gagement may be delayed after restarting
the engine if the ignition switch is not turned
to the LOCK position first.
PARK
This range supplements the parking brake by
locking the transmission. The engine can be
started in this range. Never use PARK while the
vehicle is in motion. Apply the parking brakewhen leaving the vehicle in this range. Always
apply the parking brake first, then place the
shift lever into the PARK position.
WARNING!
•
Never use the PARK position as a substi-
tute for the parking brake. Always apply the
parking brake fully when parked to guard
against vehicle movement and possible
injury or damage.
• It is dangerous to move the shift lever out of
PARK or NEUTRAL if the engine speed is
higher than idle speed. If your foot is not
firmly on the brake pedal, the vehicle could
accelerate quickly forward or in reverse.
You could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and
when your right foot is firmly on the brake
pedal.
REVERSE
This range is for moving the vehicle backward.
Use only after the vehicle has come to a
complete stop. NEUTRAL
This range is used when vehicle is standing for
prolonged periods with engine running. Engine
may be started in this range. Set the parking
brake if you must leave the vehicle.
NOTE:
Towing the vehicle, coasting, or driving for
any other reason with the shift lever in
NEUTRAL can result in 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 selected only when the
vehicle is at a complete stop and the brakes
are firmly applied. The transmission automati-
cally upshifts through fifth gear. The DRIVE
position provides optimum driving characteris-
tics under all normal operating conditions.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control
allows you to move the shift lever left (-) or right
(+) when the shift lever is in the DRIVE position,
allowing you to limit the highest available gear.
206
The “TOW/HAUL Indicator Light” will illuminate
in the instrument cluster to indicate when the
switch has been activated. Pressing the switch
a second time restores normal operation. If the
TOW/HAUL mode is desired, the switch must
be pressed each time the engine is started.
In high ambient temperatures with sustained
high engine speed and load, an upshift, fol-
lowed shortly thereafter by a downshift, may
occur. The “TOW/HAUL Indicator Light” will
turn off. This is a normal part of the overheat
protection strategy when operating in the TOW/
HAUL mode.
Transmission Limp Home Mode
Transmission function is monitored for abnor-
mal conditions. If a condition is detected that
could result in transmission damage, the Trans-
mission Limp Home Mode will be engaged. In
this mode, the transmission will remain in the
current gear (3.6L and 3.0L Diesel engine) or in
direct gear (5.7L engine) until the vehicle is
brought to a stop.To reset the transmission, use the following
procedure:
1. Stop the vehicle.
2. Move the shift lever into the PARK position.
3. Turn the engine off, and be sure to turn the
ignition switch to the LOCK position.
4. Wait approximately 10 seconds, then restart
the engine.
5. Move the shift lever to the desired gear
range.
If the problem is no longer detected, the trans-
mission will return to normal operation. If the
problem persists, PARK, REVERSE, and NEU-
TRAL will continue to operate. Only second
gear (3.6L and 3.0L Diesel engine) or third gear
(5.7L engine) will be available in the DRIVE
position. Have the transmission checked at
your authorized dealer as soon as possible.
Torque Converter Clutch
A feature, designed to improve fuel economy,
has been included in the automatic transmis-
sion on your vehicle. A clutch within the torque
converter engages automatically, at a cali-brated speed, at light throttle. It engages at
higher speeds under heavier acceleration. This
may result in a slightly different feeling or
response during normal operation in high gear.
When the vehicle speed drops below a cali-
brated speed, or during acceleration, the
clutch automatically and smoothly disengages.
NOTE:
•
The torque converter clutch will not en-
gage until the transmission fluid and en-
gine coolant are warm [usually after 1 to
3 miles (1.6 to 4.8 km) of driving]. Because
the engine speed is higher when the
torque converter clutch is not engaged, it
may seem as if the transmission is not
shifting into Overdrive when cold. This is
normal. Manually shifting (using the ERS
shift control) between 4 (direct gear) and
5/D (Overdrive gear) positions will dem-
onstrate that the transmission is able to
shift into and out of Overdrive. For ve-
hicles with 5.7L engines (which have two
Overdrive gears), the transmission may
not shift into the top Overdrive gear (nor-
mal fifth gear) until the transmission fluid
and engine coolant are warm.
209
When additional traction is required, the 4WD
LOW position can be used to lock the front and
rear driveshafts together and force the front
and rear wheels to rotate at the same speed.
The 4WD LOW position is intended for loose,
slippery road surfaces only. Driving in the 4WD
LOW position on dry, hard-surfaced roads may
cause increased tire wear and damage to
driveline components.
When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that
of the 4WD HI position at a given road speed.
Take care not to overspeed the engine and do
not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type, and
circumference on each wheel. Any difference
will adversely affect shifting and cause damage
to the transfer case.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe
turning and stopping speeds. Do not go faster
than road conditions permit.WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in
the N (Neutral) position without first fully en-
gaging the parking brake. The transfer case N
(Neutral) position disengages both the front
and rear driveshafts from the powertrain and
will allow the vehicle to move regardless of the
transmission position. The parking brake
should always be applied when the driver is
not in the vehicle.
Shift Positions
For additional information on the appropriate
use of each transfer case mode position, see
the information below:
4WD AUTO
This range is used on surfaces such as ice,
snow, gravel, sand, and dry hard pavement.NOTE:
Refer to “Selec-Terrain
– If Equipped” in
“Starting and Operating” for further infor-
mation on the various positions and their
intended usages.
NEUTRAL
This range disengages both the front and rear
driveshafts from the powertrain. It is to be used
for flat towing behind another vehicle. Refer to
“Recreational Towing” in “Starting and Operat-
ing” for further information.
4WD LOW
This range is for low speed four-wheel drive. It
locks the front and rear driveshafts together
and forces the front and rear wheels to rotate at
the same speed. It provides additional traction
and maximum pulling power for loose, slippery
road surfaces only. Do not exceed 25 mph
(40 km/h).
NOTE:
Refer to “Selec-Terrain – If Equipped” for
further information on the various positions
and their intended usages.
211
Shifting Procedures
4WD HI to 4WD LOW
With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition switch in the ON position or
the engine running, shift the transmission into
NEUTRAL, and press the “4WD LOW” button
once on the transfer case switch. The “4WD
LOW” indicator light in the instrument cluster
will begin to flash and remain on solid when the
shift is complete.
NOTE:
If shift conditions/interlocks are not met, or
a transfer case motor temperature protec-tion condition exists, a “For 4x4 Low Slow
Below 3 MPH or 5 KPH Put Trans in N Press
4 Low” message will flash from the Elec-
tronic Vehicle Information Center (EVIC). Re-
fer to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument
Panel” for further information.
4WD LOW to 4WD HI
With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition switch in the ON position or
the engine running, shift the transmission into
NEUTRAL, and press the “4WD LOW” button
once on the transfer case switch. The “4WD
LOW” indicator light in the instrument cluster
will flash and go out when the shift is complete.
NOTE:
•
If shift conditions/interlocks are not met,
or a transfer case motor temperature pro-
tection condition exists, a “For 4x4 High
Slow Below 3 MPH or 5 KPH Put Trans in
N Press 4 Low” message will flash from
the Electronic Vehicle Information Center
(EVIC). Refer to “Electronic Vehicle Infor- mation Center (EVIC)” in “Understanding
Your Instrument Panel” for further infor-
mation.
• Shifting into or out of 4WD LOW is pos-
sible with the vehicle completely stopped;
however, difficulty may occur due to the
mating clutch teeth not being properly
aligned. Several attempts may be re-
quired for clutch teeth alignment and shift
completion to occur. The preferred
method is with the vehicle rolling 0 to
3 mph (0 to 5 km/h). If the vehicle is
moving faster than 3 mph (5 km/h), the
transfer case will not allow the shift.
NEUTRAL Shift Procedure
1. Turn the ignition switch to the ON position,
engine off.
2. Vehicle stopped, with foot on brake.
3. Place the transmission into NEUTRAL.
4. Hold down the NEUTRAL “pin” switch (with
a pen, etc.) for four seconds until the LED light
by the switch starts to blink indicating shift in
progress. The light will stop blinking (stay on
solid) when the NEUTRAL shift is complete. A
