The transmission may automatically
downshift from the higher gear to
the lower gear under these
conditions:
Driving on level roads and downhill
To shift from Speed range
4 3 under 18 mph
(29 km/h)
5 4 under 38 mph
(60 km/h)
Driving uphill
To shift from Speed range
4 3 under 34 mph
(55 km/h)
5 4 under 47 mph
(75 km/h)
Downshifting gives you more power
when climbing, and provides engine
braking when going down a steep hill.
The transmission will also shift
automatically as the vehicle comes to
a complete stop. It will downshift to
first gear when the vehicle speed is
under 9 mph (15 km/h).
If you try to manually downshift at a
speed that would cause the engine to
exceed the redline in a lower gear,
the transmission will not downshift.
The gear indicator will flash the
number of the lower gear several
times, then return to the higher gear.
Automatic Transmission
If the vehicle speed slows to below
the redline of the selected lower gear
position while the indicator is
flashing, the transmission will
downshift and the display will show
the selected lower gear.
The table shows the speed ranges
for upshifting and downshifting.
To shift from Speed range
1 2 over 0 mph
(0 km/h)
2 3 over 9 mph
