FOURTH (4): This position is also used for normal
driving. However, it reduces vehicle speed more than
DRIVE (D) without using your brakes. You might choose
FOURTH (4) instead of DRIVE (D) when driving on
hilly, winding roads and when going down a steep hill.
INTERMEDIATE (I): This position is also used for
normal driving. However, it reduces the vehicle's
speed without using your brakes, for slight downgrades
where the vehicle would otherwise accelerate due
to steepness of grade. If constant upshifting or
downshifting occurs while driving on steep hills, this
position can be used to prevent repetitive types of shifts.
You might choose INTERMEDIATE (I) instead of
DRIVE (D) when driving on hilly and winding roads.
LOW (L): This position reduces vehicle speed more
than INTERMEDIATE (I) without using your brakes.
You can use it on very steep hills, or in deep snow or
mud. If the shift lever is put in LOW (L), the transmission
will not shift into low gear until the vehicle is going
slowly enough.
Notice: Spinning the tires or holding the vehicle
in one place on a hill using only the accelerator
pedal may damage the transmission. If you
are stuck, do not spin the tires. When stopping on
a hill, use the brakes to hold the vehicle in place.

Manual Transmission Operation
Here is how to operate your manual transmission:
FIRST (1): Press the clutch pedal and shift into
FIRST (1). Then, slowly let up on the clutch pedal
as you press the accelerator pedal.
You can shift into FIRST (1) when you are going less
than 20 mph (32 km/h). If you have come to a complete
stop and it is hard to shift into FIRST (1), put the shift
lever in NEUTRAL and let up on the clutch pedal. Press
the clutch pedal back down. Then shift into FIRST (1).
SECOND (2): Press the clutch pedal as you let up
on the accelerator pedal and shift into SECOND (2).
Then, slowly let up on the clutch pedal as you press
the accelerator pedal.
This is the shift pattern for
a manual transmission.
