During extremely cold temperatures (-22°F [-30°C] or
below), transmission operation may be modified
depending on engine and transmission temperature as
well as vehicle speed. Normal operation will resume
once the transmission temperature has risen to a suit-
able level.
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).
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 transmission will return to
normal operation.
NOTE:
Even if the transmission can be reset, we recommend
that you visit an authorized dealer at your earliest pos-
sible 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.
Electronic Range Select (ERS) Operation
The ERS shift control allows the driver to limit the high-
est available gear when the transmission is in DRIVE.
For example, if you set the transmission gear limit to
FOURTH gear, the transmission will not shift above
FOURTH gear (except to prevent engine overspeed), but
will shift through the lower gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the transmission 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 clus-
ter, and set that gear as the top available gear. Once in
ERS mode, tapping the GEAR “–” or GEAR “+” switch
will change the top available gear.
To exit ERS mode, simply push and hold the GEAR “+”
switch until the gear limit display disappears from the
instrument cluster.
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.
When to Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting
occurs, push the TOW/HAUL switch to activate TOW/
HAUL mode. This will improve performance and reduce
the potential for transmission overheating or failure due
to excessive shifting.
