STARTING AND OPERATING 59
If the transmission becomes extremely hot, the
Transmission Temperature Warning Light may
illuminate and the transmission may operate
differently until the transmission cools down.
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, and shifts into EIGHTH or NINTH gear, are
inhibited until the transmission fluid is warm
Ú
page 59. Normal operation will resume once
the transmission temperature has risen to a
suitable 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 transmission may operate only in a fixed
gear, or may remain in NEUTRAL. The Malfunction
Indicator Light (MIL) may be illuminated. Limp
Home Mode may allow the vehicle to be driven to
an authorized dealer for service without damaging
the transmission.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition OFF.
4. Wait approximately 10 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
possible convenience. An authorized dealer has diag-
nostic equipment to assess the condition of your
transmission. If the transmission cannot be reset,
authorized dealer service is required.
Torque Converter Clutch
A feature designed to improve fuel economy has
been included in the automatic transmission on
your vehicle. A clutch within the torque converter
engages automatically at calibrated speeds. This
may result in a slightly different feeling or response
during normal operation in the upper gears. When
the vehicle speed drops or during some
accelerations, the clutch automatically
disengages.
NOTE:
The torque converter clutch will not engage until
the transmission fluid is warm [usually after 1 to
3 miles (2 to 5 km) of driving]. Because the engine
speed is higher when the torque converter clutch is
not engaged, it may seem as if the transmission is
not shifting properly when cold. This is normal. The
torque converter clutch will function normally once
the transmission is sufficiently warm.
Electronic Range Select (ERS) Operation
The ERS shift control allows the driver to limit the
highest available gear. For example, if you set the
transmission gear limit to FIFTH gear, the
transmission will not shift above FIFTH gear, but
will shift through the lower gears normally.
You can switch between DRIVE and ERS mode at
any vehicle speed. When the gear selector is in the
DRIVE position, the transmission will operate
automatically, shifting between all available gears.
Moving the gear selector to the ERS position (beside
DRIVE) will activate ERS mode, display the current
gear in the instrument cluster, and set that gear as
the top available gear. Once in ERS mode, moving
the gear selector forward “-” or rearward “+” will
change the top available gear, which will be
displayed in the instrument cluster.
To exit ERS mode, simply return the gear selector
to the DRIVE position.
