•Bi-Level Mode
Air comes from both the headliner outlets and the
floor outlets.
NOTE: In many temperature positions, the Bi-Level
mode is designed to provide cooler air out of the head-
liner outlets and warmer air from the floor outlets.
• Floor Mode
Air comes from the floor outlets. Recirculation Control
When outside air contains smoke, odors, or high humid-
ity, or if rapid cooling is desired, you may wish
to recirculate interior air by pressing the Recir-
culation control button. Recirculation mode
should only be used temporarily. The recircu-
lation LED will illuminate when this button is selected.
Push the button a second time to turn off the Recircula-
tion mode LED and allow outside air into the vehicle.
NOTE: In cold weather, use of the Recirculation mode
may lead to excessive window fogging. The Recirculation
mode is not allowed in Defrost mode to improve window
clearing operation. Recirculation will be disabled auto-
matically if this mode is selected.

Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
A solution of 50% ethylene glycol antifreeze coolant and
50% water is recommended. Refer to “Maintenance Pro-
cedures” in “Maintaining Your Vehicle” for proper cool-
ant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “MaintenanceProcedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended, because it
may cause window fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes, in
fresh air with the blower setting on high. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.

Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the transmission
shifter in PARK unless the brakes are applied. To shift the
transmission out of PARK, the engine must be running
and the brake pedal must be pressed.
In 8-speed vehicles, the brake pedal must also be pressed
to shift from NEUTRAL into DRIVE or REVERSE when
the vehicle is stopped or moving at low speeds.
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.

STARTING AND OPERATING 471
Page 474 of 700

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.
Six-Speed Automatic Transmission
The transmission gear position display (located in the
instrument cluster) indicates the transmission gear range.
You must press the brake pedal to move the shift lever
out of PARK (Refer to “Brake/Transmission Shift Inter-
lock System” in this section). To drive, move the shift
lever from PARK or NEUTRAL to the DRIVE position.
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).
472 STARTING AND OPERATING
Page 480 of 700

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.
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 be
limited 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.
478 STARTING AND OPERATING
Page 481 of 700

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.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is nolonger 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
not shift above third gear (except to prevent engine
overspeed), but will shift down into second and first
gears normally.5

Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer and will take the appropriate
actions to attempt to stop the sway. The system may
reduce engine power and apply the brake of the appro-
priate wheel(s) to counteract the sway of the trailer. TSC
will become active automatically once an excessively
swaying trailer is recognized. No driver action is re-
quired. Note that TSC cannot stop all trailers from
swaying. Always use caution when towing a trailer and
follow the trailer tongue weight recommendations. Refer
to “Trailer Towing” in this section for further informa-
tion. When TSC is functioning, the “ESC Activation/Malfunction Indicator Light” will flash, the engine power
may be reduced and you may feel the brakes being
applied to individual wheels to attempt to stop the trailer
from swaying. TSC is disabled when the ESC system is in
the “Partial Off” mode.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
