164 STARTING AND OPERATING
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, some
gears will be unavailable. The transmission will
operate only in a certain select set of gears
(such as FIRST, SECOND, THIRD, and REVERSE,
or FIRST, THIRD, FIFTH, and REVERSE, or
SECOND, FOURTH, and SIXTH [with no
REVERSE]). PARK and NEUTRAL will continue to
be available. The Malfunction Indicator Light
(MIL) may be illuminated. 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 to the OFF position.
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 autho-
rized dealer has diagnostic equipment to deter-
mine if the problem could recur.
If the transmission cannot be reset, authorized
dealer service is required.
FOUR-WHEEL DRIVE OPERATION — IF
EQUIPPED
JEEP ACTIVE DRIVE
Your vehicle may be equipped with a Power
Transfer Unit (PTU). This system is automatic
with no driver inputs or additional driving skills
required. Under normal driving conditions, the
front wheels provide most of the traction. If the
front wheels begin to lose traction, power is
shifted automatically to the rear wheels. The
greater the front wheel traction loss, the greater
the power transfer to the rear wheels.
Additionally, on dry pavement under heavy
throttle input (where one may have no wheel
spin), torque will be sent to the rear in a
preemptive effort to improve vehicle launch and
performance characteristics.
