LOW TWO (L2): This position gives you more power
but lower fuel economy. You can use LOW TWO (L2) 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: Do not drive in LOW TWO (L2) for more
than 25 miles (40 km), or at speeds over 55 mph
(90 km/h), or you can damage your transaxle.
Use AUTOMATIC OVERDRIVE (D) or LOW FOUR (L4)
as much as possible. Do not shift into LOW
TWO (L2) unless you are going slower than 65 mph
(105 km/h) or you can damage your engine.
Notice: Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transaxle. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
Transaxle Overheating
If the transaxle fluid temperature rises above 284°F
(140°C) or rises rapidly, the Engine Coolant
Temperature Warning Light will flash. See Engine
Coolant Temperature Warning Light on page 3-31 for
more information. When the transaxle overheats it
will go into a protection mode and will default shift into
fifth gear if in the AUTOMATIC OVERDRIVE (D)
position, or second gear if in the LOW TWO (L2)
position. Continue driving the vehicle in either position
depending on the required vehicle speed and load. Once
the fluid temperature lowers to the normal temperature
range, the transaxle will return to the normal shift
patterns. Towing or driving on long hills can cause the
transaxle fluid temperature to be higher than normal.
If the transaxle fluid temperature will not cool, you may
need to pull over and check the transaxle fluid level.
You should also check the engine coolant temperature.
If it is hot, see Engine Overheating on page 5-24.
