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 trans-
mission 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 instru-
ment 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 message indi-
cates the transmission may not re-engage after
engine shutdown, perform this procedure only in a
desired location (preferably, at an authorized
dealer).
•
Even if the transmission can be reset, we recom-
mend that you visit an authorized dealer at your
earliest possible convenience. An authorized dealer
has diagnostic equipment to assess the condition of
your transmission.
•
If the transmission cannot be reset, authorized
dealer service is required.
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not,
shift the transmission to NEUTRAL.
3. Push and hold the ENGINE START/STOP button 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.
AutoStick
AutoStick is a driver-interactive transmission feature
providing manual shift control, giving you more control
of the vehicle. AutoStick allows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This feature
can also provide you with more control during passing,
city driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.
Operation
To activate AutoStick mode, move the gear selector into
the MANUAL (M) position (beside the DRIVE position).
The current transmission gear will be displayed in the
instrument cluster. In AutoStick mode, you can use the
gear selector (in the MANUAL position) to manually shift
the transmission. Tapping the gear selector forward (-)
while in the MANUAL (M) position will downshift the
transmission to the next lower gear. Tapping the selec-
tor rearward (+) will command an upshift.
In AutoStick mode, the transmission will shift up or
down when (+/-) is manually selected by the driver,
unless an engine lugging or overspeed condition would
result. It will remain in the selected gear until another
upshift or downshift is chosen, except as follows:
•
The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
STARTING AND OPERATING
•
The transmission will automatically downshift to
FIRST gear when coming to a stop. After a stop, the
driver should manually upshift (+) the transmission
as the vehicle is accelerated.
•
You can start out, from a stop, in FIRST or SECOND
gear (or THIRD gear, in 4L range). Tapping (+) (at a
stop) will allow starting in SECOND gear. Starting out
in SECOND or THIRD gear can be helpful in snowy or
icy conditions.
•
If a requested downshift would cause the engine to
overspeed, that shift will not occur.
•
The system will ignore attempts to upshift at too low
of a vehicle speed.
•
Holding the gear selector in the (-) position will
downshift the transmission to the lowest gear pos-
sible at the current speed.
•
Transmission shifting will be more noticeable when
AutoStick is enabled.
•
The system may revert to automatic shift mode if a
fault or overheat condition is detected.
NOTE:
When Hill Descent Control is enabled, AutoStick is not
active.
To disengage AutoStick mode, return the gear selector
to the DRIVE position. You can shift in or out of the
AutoStick position at any time without taking your foot
off the accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.
