Fuel Economy (ECON) Mode
The Fuel Economy (ECON) mode can improve the vehi-
cle’s overall fuel economy during normal driving condi-
tions. Press the “econ” switch in the center stack of the
instrument panel and a green light will indicate the
ECON mode is engaged.When the Fuel Economy (ECON) Mode is engaged, the
vehicle control systems will change the following:
•The transmission will upshift sooner and downshift
later.
•The transmission will skip select gears during shifts to
allow the engine to operate at lower speeds.
•The torque converter clutch will engage at lower
engine speeds and remain on longer.
•The engine idle speed will be lower.
•The overall driving performance will be more conser-
vative.
•Some ECON mode functions may be temporarily
inhibited based on temperature and other factors.

STARTING AND OPERATING 425

The transmission shift lever has only PARK, REVERSE,
NEUTRAL, and DRIVE shift positions. Manual shifts can
be made using the Electronic Range Select (ERS) shift
control (described later in this section). Moving the shift
lever to the left or right (–/ +) while in the DRIVE
position will select the highest available transmission
gear, and will display that gear in the instrument cluster
as 6, 5, 4, 3, 2, 1.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in
motion. Apply the parking brake when leaving the
vehicle in this range.When parking on a level surface, you may place the shift
lever in the PARK position first, and then apply the
parking brake.
When parking on a hill, apply the parking brake before
placing the shift lever in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the shift lever out of PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade, and away from the curb on an uphill grade.
WARNING!
•Never use the PARK position as a substitute for
the parking brake. Always apply the parking
brake fully when parked to guard against vehicle
movement and possible injury or damage.

STARTING AND OPERATING 427

WARNING! (Continued)
•Your vehicle could move and injure you and others
if it is not completely in PARK. Check by trying to
move the shift lever rearward (with the brake
pedal released) after you have placed it in PARK.
Make sure the transmission is in PARK before
leaving the vehicle.
•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 pressing 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
your foot is firmly pressing the brake pedal.(Continued)
WARNING! (Continued)
•Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, always apply the
parking brake, shift the transmission into PARK,
and remove the key fob. Once the key fob is
removed, the shift lever is locked in the PARK
position, securing the vehicle against unwanted
movement. Furthermore, you should never leave
unattended children inside a vehicle.
•When leaving the vehicle, always remove the key
fob from the ignition and lock your vehicle.
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle.(Continued)
428 STARTING AND OPERATING

WARNING! (Continued)
•Allowing children to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured. Chil-
dren should be warned not to touch the parking
brake, brake pedal or the shift lever.
•Do not leave the key fob in or near the vehicle. A
child could operate power windows, other con-
trols, or move the vehicle.
CAUTION!
•Before moving the shift lever out of PARK, you
must turn the ignition switch from the LOCK/OFF
position to the ON/RUN position, and also press
the brake pedal. Otherwise, damage to the shift
lever could result.(Continued)
CAUTION! (Continued)
•DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as
this can damage the drivetrain.
The following indicators should be used to ensure that
you have engaged the shift lever into the PARK position:
•When shifting into PARK, firmly move the shift lever
all the way forward and to the left until it stops and is
fully seated.
•Look at the shift lever position display and verify that
it indicates the PARK position.
•With brake pedal released, verify that the shift lever
will not move out of PARK.

STARTING AND OPERATING 429

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 engine running. The engine may be started
in this range. Set the parking brake and shift the trans-
mission 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 result
in severe transmission damage. Refer to “Recre-
ational Towing” in “Starting And Operating” and
“Towing A Disabled Vehicle” in What To Do In
Emergencies” for further information.
DRIVE
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 underdrive first, second,
third, and fourth gears, direct fifth gear and overdrive
sixth gear. The DRIVE position provides optimum driv-
ing characteristics under all normal operating conditions.
430 STARTING AND OPERATING

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 (described below) to select a
lower gear range. Under these conditions, using a lower
gear range will improve performance and extend trans-
mission life by reducing excessive shifting and heat
buildup.
During cold temperatures, transmission operation may
be modified depending on engine and transmission
temperature as well as vehicle speed. This feature im-
proves warm up time of the engine and transmission to
achieve maximum efficiency. Engagement of the torque
converter clutch is inhibited until the transmission fluid
is warm (refer to the “Note” under “Torque Converter
Clutch” in this section). During extremely cold tempera-
tures (-16°F [-27°C] or below), operation may briefly belimited to third gear only. Normal operation will resume
once the transmission temperature has risen to a suitable
level.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in third gear regardless of which forward gear is selected.
PARK, REVERSE, and NEUTRAL will continue to oper-
ate. The Malfunction Indicator Light (MIL) may be illu-
minated. Limp Home Mode allows the vehicle to be
driven to an authorized dealer for service without dam-
aging 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.
5
STARTING AND OPERATING 431

2. Shift the transmission into PARK.
3. Turn the engine OFF.
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 recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic 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 transmission into 3 (third gear), the transmission will
never shift above third gear, but will shift down into
second and first gear 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 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, tapping
the shift lever to the left (-) or right (+) will change the top
available gear.
432 STARTING AND OPERATING

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 braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing an accident
or personal injury.

NOTE: To select the proper gear position for maximum
deceleration (engine braking), tap the shift lever to the
left (-) repeatedly as the vehicle slows. The transmission
will shift to the range from which the vehicle can best be
slowed down.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (sixth gear). The transmission will
automatically shift into the Overdrive gear if the follow-
ing conditions are present:
•the shift lever is in the DRIVE position,
•the transmission fluid has reached an adequate tem-
perature,
•the engine coolant has reached an adequate tempera-
ture,
•vehicle speed is sufficiently high, and
•the driver is not heavily pressing the accelerator
5
STARTING AND OPERATING 433

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.
NOTE:The torque converter clutch will not engage
until the transmission fluid and engine 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. Using the Electronic Range Select (ERS)
feature, when the transmission is sufficiently warm, will
demonstrate that the transmission is able to shift into and
out of Overdrive.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the driving wheels to pull
erratically to the right or left. This phenomenon occurs
when there is a difference in the surface traction under
the front (driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the
front wheels. You could lose control of the vehicle
and possibly have a collision. Accelerate slowly and
carefully whenever there is likely to be poor traction
(ice, snow, wet mud, loose sand, etc.).
434 STARTING AND OPERATING

Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following Caution
and Warning before doing so.
CAUTION!
•Always check the depth of the standing water
before driving through it. Never drive through
standing water that is deeper than the bottom of
the tire rims mounted on the vehicle.
•Determine the condition of the road or the path
that is under water and if there are any obstacles in
the way before driving through the standing wa-
ter.
•Do not exceed 5 mph (8 km/h) when driving
through standing water. This will minimize wave
effects.(Continued)
CAUTION! (Continued)
•Driving through standing water may cause dam-
age to your vehicle’s drivetrain components. Al-
ways inspect your vehicle’s fluids (i.e., engine oil,
transmission, axle, etc.) for signs of contamination
(i.e., fluid that is milky or foamy in appearance)
after driving through standing water. Do not con-
tinue to operate the vehicle if any fluid appears
contaminated, as this may result in further dam-
age. Such damage is not covered by the New
Vehicle Limited Warranty.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
