Soft-Key
Use the small blower icon to reduce the blower setting
and the large blower icon to increase the blower setting.
Blower can also be selected by pressing the blower bar
area between the icons.
11. Modes
The airflow distribution mode can be adjusted so air
comes from the instrument panel outlets, floor outlets,
demist outlets and defrost outlets. The Mode settings are
as follows:•Panel Mode
Air comes from the outlets in the instrument
panel. Each of these outlets can be individu-
ally adjusted to direct the flow of air. The air vanes of
the center outlets and outboard outlets can be moved
up and down or side to side to regulate airflow direction. There is a shut off wheel located below the
air vanes to shut off or adjust the amount of airflow
from these outlets.
• Bi-Level Mode
Air comes from the instrument panel outlets
and floor outlets. A slight amount of air is
directed through the defrost and side window demis-
ter outlets.
NOTE: BI-LEVEL mode is designed under comfort con-
ditions to provide cooler air out of the panel outlets and
warmer air from the floor outlets.
• Floor Mode
Air comes from the floor outlets. A slight
amount of air is directed through the defrost
and side window demister outlets.

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).
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake pedal when
shifting between these gears.
The transmission gear selector has only PARK, RE-
VERSE, NEUTRAL, and DRIVE positions. Manual down-
shifts can be made using the Electronic Range Select
(ERS) switches (described later in this section). Pressing
the GEAR-/GEAR+ switches (on the steering wheel)
while in the DRIVE position will select the highest
available transmission gear, and will display that gear in
the instrument cluster as 1, 2, 3, etc.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
Electronic Transmission Gear Selector
404 STARTING AND OPERATING
Page 407 of 806

NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating.
This is especially important when the engine is cold.
PARK (P)
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 shift the
transmission into PARK first, and then apply the parking
brake.
When parking on a hill, apply the parking brake before
shifting the transmission to 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. NOTE:
On four-wheel drive vehicles be sure that the
transfer case is in a drive position.
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 move-
ment and possible injury or damage.
• Your vehicle could move and injure you and others
if it is not in PARK. Make sure the transmission is
in PARK before leaving the vehicle.

4. Wait approximately 30 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 —
Eight-Speed Transmission
The Electronic Range Select (ERS) switches allow the
driver to limit the highest available gear when the
transmission is in DRIVE. For example, if you shift the
transmission into 3 (third gear), the transmission will not
shift above third gear (except to prevent engine over-
speed), but will shift down into second and first gears
normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the gear selector is in DRIVE, the
transmission will operate automatically, shifting between
all available gears. Tapping the GEAR- switch (on the
steering wheel) 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 GEAR- or GEAR+ switch will change the top avail-
able gear.
