µ To shif t f rom second to
first, pull the shift lever towards you,
then shif t to the lower gear. This
position locks the transmission in
f irst gear. By upshif ting and
downshif ting through 1, 2, and D,
you can operate the transmission
much like a manual transmission
without a clutch pedal.
To shif t to second,
pull the shif t lever towards you, then
shif t to the lower gear. This position
locks the transmission in second
gear. It does not downshif t to f irst
gear when you come to a stop.
Use second gear: For more power when climbing.
To increase engine braking when
going down steep hills.
For starting out on a slippery
surf ace or in deep snow.
To help reduce wheel spin.
When driving downhill with a
trailer.
When towing a trailer on level roads
under normal driving conditions, do
not use D3. This will increase the
automatic transmission fluid
temperature and may cause
overheating.
Shif ting out of the D position will
cancel D3, and cause the D3
indicator to go out. Selecting the D
position again will resume D3, and
the indicator will come on.
Turning the ignition switch to LOCK
(0) turns D3 of f . To use D3 when
you restart the engine, select the D
position and press the D3 switch
again.
TheD3indicatoralsocomesonfora
f ew seconds when you turn the
ignition switch to ON (II).
If you shif t into f irst position when
the vehicle speed is above 28 mph
(45 km/h), the transmission shif ts
into second gear first to avoid
sudden engine braking.
If you exceed the maximum speed
f or the gear you are in, the engine
speed will enter into the tachometer’s
red zone. If this occurs, you may f eel
the engine cut in and out. This is
caused by a limiter in the engine’s
computer controls. The engine will
run normally when you reduce the
rpm below the red zone.
