• 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 overdrive 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 key 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.
REVERSE SENSING SYSTEM
The Reverse Sensing System (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when the R (Reverse) is selected and the
vehicle is moving at speeds less than 3 mph (5 km/h). The system is not
effective at speeds above 3 mph (5 km/h) and may not detect certain
angular or moving objects.
WARNING: To help avoid personal injury, please read and
understand the limitations of the reverse sensing system as
contained in this section. Reverse sensing is only an aid for some
(generally large and fixed) objects when moving in reverse on a flat
surface at "parking speeds". Inclement weather may also affect the
function of the RSS; this may include reduced performance or a false
activation.
