Jeep Compass 2020 - Four-Wheel Drive Operation - if Equipped; Jeep Active Drive

262 STARTING AND OPERATING
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 equip-
ment 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 acceler-
ations, the clutch automatically disengages.
NOTE:
The torque converter clutch will not engage until the engine
and/or transmission 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 the vehicle is
cold. This is normal. The torque converter clutch will func-
tion normally once the powertrain is sufficiently warm.
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 auto-
matically to the rear wheels. The greater the front wheel trac-
tion 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.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire size
may cause failure of the power transfer unit.
