shifts 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 conditions, in hilly terrain or trav-
eling into strong head winds), use the AutoStick
shift control (refer to "AutoStick" in this section
for further information) to select a lower gear.
Under these conditions, using a lower gear will
improve performance and extend transmission
life by reducing excessive shifting and heat
buildup.
During extremely cold temperatures (-22°F
[-30°C] or below), transmission operation may
be modified depending on engine and transmis-
sion temperature as well as vehicle speed.
Normal operation will resume once the trans-
mission 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; refer to "AutoStick" in this section for
186
further information). Toggling the shift lever for-
ward (-) 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 M1, M2, M3,
etc.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition is
detected that could result in transmission dam-
age, Transmission Limp Home Mode is acti-
vated. In this mode, the transmission may op-
erate only in certain gears, or may not shift at
all. Vehicle performance may be severely de-
graded 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 illumi-
nated. A message in the instrument cluster will
inform the driver of the more serious conditions,
and indicate what actions may be necessary.
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 mes-
sage indicates the transmission may not
re-engage after engine shutdown, perform
this procedure only in a desired location
(preferably, at your authorized dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible.
If not, shift the transmission to NEUTRAL.
3. Press 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 transmis-
sion will return to normal operation.
