DRIVE (D): Use this for normal driving. If you need
more power for passing, and you’re:
D Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
D Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
The transmission will shift down to the next gear.
THIRD (3): This position is not used for normal
driving. It offers more power and lower fuel economy
than DRIVE (D).
Here are some times you might choose THIRD (3)
instead of DRIVE (D):
D When driving on hilly, winding roads.
D When towing a trailer, so there is less shifting
between gears.
D When going down a steep hill.
SECOND (2): Driving in this position gives you more 
power than driving in THIRD (3). Use it on hills. It can help 
control your speed as you go down steep mountain roads, but 
then you would also want to use the brakes off and on.
FIRST (1): This position gives you more power (but
lower fuel economy) than SECOND (2). You can use it
on very steep hills. If the shift lever is put in FIRST (1),
the transmission won’t shift into first gear until the
vehicle is going slowly enough.
NOTICE:
If the rear wheels can’t rotate, don’t try to drive.
This might happen if you were stuck in very deep
sand or mud or you were up against a solid
object. You could damage the transmission.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transmission. Use the brakes to hold your vehicle
in position on a hill.
Note: When you start your vehicle and the engine
temperature is below 86
_F (30_ C), upshifting of the
transmission will be delayed for about one minute. This
is normal. The engine’s catalytic converter is warming
up during this time.
Upshifting and downshifting of the transmission is
automatically modified to prevent undesired shifting when
your vehicle is towing a trailer or when you are driving in
hilly or mountainous terrain. This is also normal.
