• The over drive cancel and grade
assist lamp in the instrument
cluster is illuminated.
2. Grade Assist
• Improves driving experience in hilly terrain or mountainous areas by
providing additional grade (engine) braking and extends lower gear
operation on uphill climbs.
• Provides additional engine braking through the automatic transmission
shift strategy which reacts to vehicle inputs (vehicle acceleration,
accelerator pedal, brake pedal and vehicle speed).
• Allows the transmission to select gears that will provide the desired
engine braking based on the vehicle inputs mentioned above. This will
increase engine RPM during engine braking.
Overdrive Cancel with Grade Assist is designed to provide optimal gear
selection in hilly terrain or mountainous areas. It is recommended that
you return to O/D (overdrive mode) on flat terrain to provide the best
fuel economy and transmission function.
To return to O/D (overdrive mode), press the transmission control switch
again.
• The over drive cancel and grade assist lamp in the instrument cluster
will not be illuminated.
• The transmission will operate in gears one through six.
O/D (overdrive mode) is automatically returned each time the engine is
turned off.
L (Low)
• Provides maximum engine braking.
• Will downshift to the lowest available gear for the current vehicle
speed; allows for first gear when vehicle reaches slower speeds.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
