Accelerator downshift
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
Overdrive switch
Each time your vehicle is started, the transmis-
sion is automatically “reset” to overdrive ON.
ON: With the engine running and the
shift selector lever in the D (Drive)
position, the transmission upshifts
into Overdrive as vehicle speed
increases.
Overdrive does not engage until the engine
has reached operating temperature.
OFF: For driving up and down long
slopes where engine braking is nec-
essary push the Overdrive switch
once. The O/D OFF indicator light
in the instrument panel comes on at
this time.
When cruising at a low speed or climbing a
gentle slope, you may feel uncomfortable shift
shocks as the transmission shifts into and out of
Overdrive repeatedly. In this case, depress the
Overdrive switch to turn the Overdrive off. The
O/D OFF indicator light in the instrument panel
comes on at this time.
When driving conditions change, depress the
Overdrive switch to turn the Overdrive on.
Remember not to drive at high speeds for ex-
tended periods of time with the Overdrive off.
This reduces fuel economy.
MANUAL TRANSMISSION
WARNING
cDo not downshift abruptly on slippery
roads. This may cause a loss of control.
cDo not over-rev the engine when shift-
ing to a lower gear. This may cause a
loss of control or engine damage.

4th, 5th and 6th gear in sequence according to
vehicle speed.To back up depress the shift lever and then move
it to the R (Reverse) position after stopping the
vehicle completely.
On the 5-speed manual transmission model, you
cannot shift directly from the 5th gear into R
(Reverse) . First shift into N (Neutral) , then in to R
(Reverse) after stopping the vehicle completely.
If it is difficult to move the shift lever into R
(Reverse) or 1 (First) , shift into N (Neutral) , then
release the clutch pedal. Fully depress the clutch
pedal again and shift into R (Reverse) or 1 (First) .

cAccelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
c
Drive at moderate speeds on the highway. Driv-
ing at high speed lowers fuel economy.
cAvoid unnecessary stopping and braking.
Maintain a safe distance behind other vehicles.
cUse a proper gear range which suits road
conditions. On level roads, shift into high
gear as soon as possible.
cAvoid unnecessary engine idling.
cKeep your engine tuned up.
cFollow the recommended periodic mainte-
nance schedule.
cKeep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
cKeep the front wheels in correct alignment.
Improper alignment increases tire wear and
lowers fuel economy.
c
Air conditioner operation lowers fuel economy.
Use the air conditioner only when necessary.
cWhen cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.
c
Use 4H or 4L position only when
necessary. Four-wheel drive operation low-
ers fuel economy.
CAUTION
cDo not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driv-
ing on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.
If the 4WD warning light turns on when
you are driving on dry hard surface
roads:
– in the 4H position, shift the 4WD shift
switch to 2WD.
– in the 4LO position for automatic
transmission vehicles, stop the ve-
hicle and shift the transmission se-
lector to the N position with the
brake pedal depressed and shift the
4WD shift switch to 2WD.
– in the 4LO position for manual trans-
mission vehicles, stop the vehicle
and shift the transmission shift lever
to the N position with the clutch
pedal depressed and shift the 4WD
shift switch to 2WD.
