STARTING AND OPERATING 471

CAUTION!
To prevent damage to the starter, do not continuously
crank the engine for more than 10 seconds at a time.
Wait 10 to 15 seconds before trying again.
If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
(Continued)
WARNING!(Continued)
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission 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 Emergen-
cies” for further information.
474 STARTING AND OPERATING

With Tip Start
If the engine fails to start after you have followed the
#Normal Starting#, “Extreme Cold Weather#and#Ex-
tended Park Starting#procedures, it may be flooded. To
clear any excess fuel, press the accelerator pedal all the
way to the floor and hold it. Then, cycle the ignition
switch to the START position and release it as soon as the
starter engages. The starter motor will disengage auto-
matically in 10 seconds. Once this occurs, release the
accelerator pedal, cycle the ignition to the LOCK posi-
tion, 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 Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
STOP/START SYSTEM — 3.2L ENGINE
The Stop/Start function is developed to reduce emis-
sions. The system will stop the engine automatically
during a vehicle stop if the required conditions are met.
Releasing the brake pedal or pressing the accelerator
pedal will automatically re-start the engine.
Automatic Mode
The Stop/Start feature is enabled after every normal
customer engine start. At that time, the system will go
into STOP/START READY and if all other conditions are
met, can go into a STOP/START AUTOSTOP ACTIVE
“Autostop” mode.

STARTING AND OPERATING 475

•Battery charge is low.
•The vehicle is on a steep grade.
•Cabin heating or cooling is in process and an accept-
able cabin temperature has not been achieved.
•HVAC is set to full defrost mode at a high blower
speed.
•HVAC set to MAX A/C.
•Engine has not reached normal operating temperature.
•The transmission is not in a forward gear.
•Hood is open.
•Vehicle is in 4LO transfer case mode.
•Brake pedal is not pressed with sufficient pressure.
Other Factors Which Can Inhibit Autostop Include:
•Fuel level.
•Accelerator pedal input.
•Engine temp too high.
•5 MPH threshold not achieved from previous AU-
TOSTOP.
•Steering angle beyond threshold.
•ACC is on and speed is set.
It may be possible for the vehicle to be driven several
times without the STOP/START system going into a
STOP/START READY state under more extreme condi-
tions of the items listed above.
To Start The Engine While In Autostop Mode
While in a forward gear, the engine will start when the
brake pedal is released or the throttle pedal is depressed.
The transmission will automatically re-engage upon en-
gine restart.

STARTING AND OPERATING 477

Fuel Economy (ECO) Mode
The Fuel Economy (ECO) mode can improve the vehi-
cle’s overall fuel economy during normal driving condi-
tions. To activate ECO mode press the “Controls” button
on the touchscreen and then press the “ECO” button on
the touchscreen. When ECO mode is engaged a green
light in the center stack of the instrument panel will be
illuminated and a green ECO light will also illuminate in
the Electronic Vehicle Information Center (EVIC) or
Driver Information Display (DID). In 4WD models, ECO
mode is only active in ’4WD Auto’ driving mode. If you
switch to another driving mode the ECO button will turn
grey and the ECO light in the instrument panel will
disappear indicating it is no longer in ECO mode. It will
automatically re-enable ECO mode when you switch
back into 4WD Auto.
Nine-Speed Automatic Transmission
The transmission gear range (PRND) is displayed both
beside the shift lever and in the Electronic Vehicle Infor-
mation Center (EVIC)/Driver Information Display
(DID). To select a gear range, press the lock button on the
shift lever and move the lever rearward or forward. You
must also press the brake pedal to shift the transmission
out of PARK, or to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or moving at low
speeds (refer to#Brake/Transmission Shift Interlock Sys-
tem#in this section). Select the DRIVE range for normal
driving.
The electronically-controlled transmission provides a
precise shift schedule. The transmission 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).
484 STARTING AND OPERATING

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
Disabled Vehicle” in “What To Do In Emergencies”
for further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through all forward gears. The
DRIVE position provides optimum driving characteris-
tics under all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling 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 for further information)
to select a lower gear range. Under these conditions,
using a lower gear range will improve performance and
extend transmission life by reducing excessive shifting
and heat buildup.
490 STARTING AND OPERATING

Moving the shift lever to the ERS position (beside
DRIVE) 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, moving the shift
lever forward (-) or rearward (+) will change the top
available gear.
To exit ERS mode, simply return the shift lever to the
DRIVE position.
WARNING!
Do not downshift for additional engine braking 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 maximum
deceleration (engine braking), move the shift lever into
the ERS position, then simply press and hold it forward
(-). The transmission will shift to the range from which
the vehicle can best be slowed down.
Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation in
the upper gears. When the vehicle speed drops or during
some accelerations, the clutch automatically disengages.
