Notice: If your vehicle seems to start up rather
slowly, or if it seems not to shift gears as you go
faster, something may be wrong with a transaxle
system sensor. If you drive very far that way, your
vehicle can be damaged. So, if this happens, have
your vehicle serviced right away. Until then, you can
use SECOND (2) when you are driving less than
35 mph (55 km/h) and AUTOMATIC OVERDRIVE (@)
for higher speeds.
THIRD (3): This position is also used for normal driving,
but it offers more power and lower fuel economy than
AUTOMATIC OVERDRIVE
(a).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE
(a):
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
between gears.
When going down a steep hill.
When drlvlng In no-highway scenarios
(Le. city streets, etc.)
SECOND (2): This position gives you more power that
THIRD (3) but lower fuel economy. You can use
SECOND (2) on hills. It can help control your speed as
you go down steep mountain roads, but then you
would also want to use your brakes off and on.
Notice: Don't drive in SECOND (2) for more than
25 miles (40 km), or at speeds over 55 mph (90 km/h),
or you can damage your transaxle. Use THIRD (3) or
AUTOMATIC OVERDRIVE
(a)
as much as possible.
Don't shift into SECOND (2) unless you are going
slower than 65 mph (105 km/h) or you can damage
your engine.
FIRST (1): This position gives you even more power
(but lower fuel economy) than SECOND (2). You can use
it on very steep hills, or in deep snow or mud. If the shift
lever is put in FIRST ( l ) , the transaxle won't shift into first
gear until the vehicle is going slowly enough.
Notice: If your front wheels won't turn, don't try to
drive. This might happen if you were stuck in
verv deep sand or mud or were up
. -
aaainst a solid
object. You could damage your transaxle. Also,
if you stop when going uphill, don't hold your
vehicle there with only the accelerator pedal. This
could overheat and damage the transaxle. Use your
brakes to hold your vehicle in position on a hill.
