162 STARTING AND OPERATING
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.
SPORT (S) — If Equipped
This mode alters the transmission's automatic
shift schedule for sportier driving. Upshift
speeds are increased to make full use of avail-
able engine power.
To access SPORT mode, push down on the gear
selector and rotate it fully clockwise, or push the
SPORT button in the center stack.
LOW (L) — If Equipped
Use this range for engine braking when
descending very steep grades. In this range, the
transmission will downshift for increased
engine braking. To access the LOW position,
push down on the gear selector and rotate it
fully clockwise.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition is
detected that could result in transmission
damage, Transmission Limp Home Mode is acti-
vated. 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 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 trans-
mission 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, if
possible. If not, shift the transmission to
NEUTRAL.
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 trans-
mission will return to normal operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit an authorized dealer
at your earliest possible convenience. An autho-
rized dealer has diagnostic equipment to
assess the condition of your transmission.
If the transmission cannot be reset, authorized
dealer service is required.
