DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest
upshifts and downshifts, and the best fuel
economy. The transmission automatically
upshifts through all forward gears.
When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain,
traveling into strong head winds, or while towing
a heavy trailer), use the AutoStick shift control
to select a lower gear Ú page 120. Under these
conditions, using a lower gear will improve
performance and extend transmission 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 improves 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. Normal operation
will resume once the transmission temperature
has risen to a suitable level.
Manual (M)
The MANUAL (M, +/-) position (beside the DRIVE
position) enables full manual control of
transmission shifting (also known as AutoStick
mode Ú page 120). Toggling the gear selector
forward (-) or rearward (+) while in the MANUAL
(AutoStick) position will manually select the
transmission gear, and will display the current
gear in the instrument cluster as 1, 2, 3, etc.
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 may operate only in certain
gears, or may not shift at all. Vehicle performance
may be severely degraded and the engine may stall.
In some situations, the transmission may not
re-engage if the engine is turned off and restarted.
The Malfunction Indicator Light (MIL) may be
illuminated. A message in the instrument cluster will
inform the driver of the more serious conditions,
and indicate what actions may be necessary.
STARTING AND OPERATING
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
NOTE:
In cases where the instrument cluster message
indicates the transmission may not re-engage
after engine shutdown, perform this procedure
only in a desired location (preferably, at an
authorized dealer):
1. Stop the vehicle.
2. Shift the transmission into PARK (P), if
possible. If not, shift the transmission to
NEUTRAL (N).
3. Push and hold the ignition switch until the
engine turns off.
4. Wait approximately 30 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.
