THIRD (3): This position is also used for normal driving,
however, it offers more power and lower fuel economy
than DRIVE (D). Here are some times you might choose
THIRD (3) instead of DRIVE (D):
•
When driving on hilly, winding roads.
•
When going down a steep hill.
SECOND (2): This position gives you more power but
lower fuel economy. Use SECOND (2) on hills. It can
help control the vehicles speed as you go down
steep mountain roads, but then you would also want to
use your brakes off and on.
Notice: Do not drive in SECOND (2) at speeds
over 65 mph (105 km/h), or you can damage
the transmission. Use THIRD (3) or AUTOMATIC
OVERDRIVE (D) as much as possible. Do not shift
into SECOND (2) unless you are going slower
than 65 mph (105 km/h) or you can damage
your engine.
2-24
FIRST (1): This position gives you even more power
but lower fuel economy than SECOND (2). Use it
on very steep hills, or in deep snow or mud. If the shift
lever is put in FIRST (1), the transmission does not
shift into first 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. The repair will
not be covered by your warranty. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
If there is a malfunction with the automatic transmission,
the Check Engine Light or the HOLD indicator light
will turn on or flash. See Malfunction Indicator Lamp
on page 3-34 or Hold Mode Light on page 3-33.
Take your vehicle to your dealer/retailer as soon
as possible.
