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.
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.
FOUR-WHEEL DRIVE OPERATION
1-Speed Four-Wheel Drive (4X4) — If Equipped
This feature provides on-demand four-wheel drive (4X4).
The system is automatic with no driver inputs or addi-
tional driving skills required. Under normal driving con-
ditions, 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
traction loss, the greater the power transfer to the rear
wheels.
