(o) Engine Oil Replacement Reminder
Light (for vehicles sold in U.S.A.)
This light acts as a reminder when to
replace the engine oil.
This light will come on when the ignition
key is turned to “ON” and will go off after
about a few seconds.
When you drive for about 7200 km (4500
miles) after the engine oil replacement,
this light illuminates for about 3 seconds
and then flashes for about 12 seconds
with the ignition key turned to the “ON”
position. If you continue driving without
replacing the engine oil, and if the dis-
tance driven exceeds 8000 km (5000
miles), the light will come on after the
ignition key is turned to “ON” position.
The light will remain on thereafter.
If the light is flashing, we recommend that
you replace the engine oil at an early
opportunity depending on the driving and
road conditions. If the light comes on,
replace it as soon as possible. The system must be reset after the en-
gine oil replacement. Reset the system by
the following procedure:
1. Turn the ignition key to the “ACC” or “LOCK” position with the odometer
reading shown. (For details, see
“Odometer and two trip meters” in this
Section.)
2. Turn the ignition key to the “ON” posi- tion while holding down the trip meter
reset knob.

drive is off and restarted, the overdrive
will automatically be on. Vehicles with cruise control—When the
cruise control is being used, even if you
downshift the transmission by pushing and
releasing the overdrive switch, engine
braking will not be enabled because the
cruise control is not cancelled.
For ways to decrease the vehicle speed,
see “Cruise control” in this Section.
(d) Normal driving
1. Start the engine as instructed in “How to start the engine” in Section 3. The
transmission must be in “P” or “N”.
2. With your foot holding down the brake pedal, shift the selector lever to “D”.
When the lever is in the “D” position, the
automatic transmission system will select
the most suitable gear for running condi-
tions such as normal cruising, hill climb-
ing, hard towing, etc.
Always turn the overdrive on for better
fuel economy and quieter driving. If the
engine coolant temperature is low, the
transmission will not shift into the over-
drive gear even with the overdrive on.
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brake pedal. Depress the accelerator pedal
slowly for smooth starting.
(e) Using engine braking

could cause the vehicle to skid or
spin.
(f) Using “3”, “2” and “L” positions
The “3”, “2” and “L” positions are used for
strong engine braking as described pre-
viously.
With the selector lever in “3”, “2” or
“SHIFT L” switch depressed, the vehicle
can move just as if the lever was in “D”.
With the selector lever in “3”, “2”, the
vehicle will start in first gear and automat-
ically shift to second gear.
With the “SHIFT L” switch depressed, the
transmission is engaged in first gear.
NOTICE

Be careful not to over −rev the en-
gine. Watch the tachometer to keep
engine rpm from going into the red
zone. The approximate maximum al-
lowable speed for each position is

Good driving practice
If it is difficult to shift into reverse, put
the transmission in neutral, release the
clutch pedal momentarily, and then try
again.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use sixth gear.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to skid or
spin.
NOTICE
Make sure the vehicle is completely
stopped before shifting into reverse.
Use the “2WD/4HI” and “4LO” switches
to select the following transfer modes.
1. “2WD” (high speed position, two −
wheel drive): “2WD/4HI” and “4LO”
switches left out
Use this for normal driving on dry,
hard− surfaced roads. This position
gives greater economy, the quietest
ride and least wear.
2. “4HI” (high speed position, four −
wheel drive): “2WD/4HI” switch pushed
in
The “4HI” (high speed four −wheel
drive) indicator light comes on when
the “4HI” mode is selected.
Use this for normal driving on wet, icy
or snow −covered roads. This position
provides greater traction than two−
wheel drive.
In this mode, the vehicle stability con-
trol system is off. (See “Vehicle stabil-
ity control system” in this Section.)
