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 remains in THIRD gear
regardless of which forward gear is selected.
PARK, REVERSE, and NEUTRAL will continue to
operate. The Malfunction Indicator Light (MIL) may
be illuminated. Transmission Limp Home Mode
allows 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.

Actual Gear(s) Allowed
NOTE:
To select the proper gear position for maximum deceleration (engine braking), move the gear selector into the ERS position, then tap it
forward "-" repeatedly as the vehicle slows. The transmission will shift to the range from which the vehicle can best be slowed down.
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 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
select the max gear limit. For example, if you
set the transmission gear limit to FOURTH gear, the
transmission will not shift above FOURTH 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 max gear limit. Once in ERS mode,
moving the gear selector forward "-" or
rearward "+" will change the max gear limit.
NOTE:
The transmission will still continue to use the
optimal highest gear, for the current driving
conditions, within the selected gear range limit.
To exit ERS mode, simply return the gear selector
to the DRIVE position.
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.
