•
First decelerate the engine sufficiently before
downshifting.
Downshifting more than two gears at a time or
downshifting at a high engine speed could
cause the engine to overrev.
Generally speaking, you should decelerate to
roughly 1‚600 rpm before downshifting.
For safety in an automatic transmission vehicle,
the transmission will automatically refuse to shift
down if the vehicle is moving too fast. Depress
the brake pedal to decelerate.
NOTE:
“Overrev” refers to an operating state of the engine
in which it rotates at an RPM higher than the recom-
mended maximum RPM. Overrevving the engine
could lead to an engine failure.
•
Use a low gear and try to drive at a constant
speed when driving on gravel roads or muddy
roads.
•
Do not race the engine when attempting to
move out of mud. Racing the engine is useless
and even worsens the condition as the spinning
wheels will make ruts deeper. Instead, place
thick waste cloth, gravel or the like under tires,
and engage the 1st and reverse gears alter-
nately or, in an automatic transmission vehicle,
select the “D” and “R” positions alternately to
move the vehicle back and forth until you can
drive out.
When shifting from “D” or “R” or vise versa,
release the accelerator pedal to lower the
engine speed to idle.
CAUTION
Do not operate an automatic transmission in
this way for more than 5 minutes since it causes
the automatic transmission fluid to heat up rap-
idly.
