(e) Low Engine Oil Pressure Warning
Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Toyota dealer or qualified repair shop for
assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.
(f) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the “ON” position and
goes off after the engine starts. This
means that the warning light system is
operating properly.
If the lamp remains on, or the lamp
comes on while driving, first check the
followings.
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
after taking several driving trips.
If the lamp does not go off even after
several trips, contact your Toyota dealer
as soon as possible. If the fuel tank is not empty or the fuel
tank cap is not loose...
There is a problem somewhere in the
engine, emission control system, elec-
tronic throttle control system, automatic
transmission electrical system or warn-
ing light system itself.
Contact your Toyota dealer as soon as
possible to service the vehicle.
If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle
checked by your Toyota dealer as soon as
possible.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the ignition key is turned to “ACC” or
“LOCK” position.

(m) Automatic Transmission Fluid
Temperature Warning Light
(fourwheel drive models)
This light warns that the automatic trans-
mission fluid temperature is too high.
If this light comes on while you are driv-
ing, slow down and pull off the road. Stop
the vehicle at a safe place and put the
selector lever in “P”. With the engine id-
ling, wait until the light goes off. If the
light goes off, you may start the vehicle
again. If the light does not go off, call a
Toyota dealer or qualified repair shop for
assistance.
(n) Low Windshield Washer Fluid Level Warning Light
This light warns that the windshield wash-
er fluid level is too low. Add washer fluid
at your earliest opportunity. (For instruc-
tions, see “Adding washer fluid” in Section
7 −3.) (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.
Hold down the knob for at least 5 sec-
onds. The odometer indicates “000000”
and the light goes off.
If the system fails to reset, the light will
continue flashing.
(p) Key Reminder Buzzer
This buzzer acts as a reminder to remove
the key when you open the driver’s door
with the ignition key in the “ACC” or
“LOCK” position.

“START”—Starter motor on. The key
will return to the “ON” position when
released.
For starting tips, see Section 3.
“ON”—Engine on and all accessories
on.
This is the normal driving position.
“ACC”—Accessories such as the radio
operate, but the engine is off.
If you leave the key in the “ACC” or
“LOCK” position and open the driver’s
door, a buzzer will remind you to remove
the key. “LOCK”—Engine is off and the steering
wheel is locked. The key can be re-
moved only at this position.
You must push in the key to turn the key
from “ACC” to the “LOCK” position. On
vehicles with an automatic transmission,
the selector lever must be in the “P” posi-
tion before pushing the key.
Once you remove the key, the engine im-
mobilizer system is automatically set. (See
“Engine immobilizer system” in Section
1
−2.)
When starting the engine, the key may
seem stuck at the “LOCK” position. To
free it, first be sure the key is pushed all
the way in, and then rock the steering
wheel slightly while turning the key gently.
Approximately five hours after the engine
is turned off, you may hear sound coming
from underneath the rear deck for several
minutes. This is normal operation and
does not indicate a malfunction. (See
“Leak detection pump”.)
It is not a malfunction if the needles on
all meters and gauges move slightly when
the key is turned to the “ACC”, “ON” or
“START” position.
CAUTION
For manual transmission:
Never remove the key when the ve-
hicle is moving, as this will lock the
steering wheel and result in loss of
steering control.
NOTICE
Do not leave the key in the “ON”
position if the engine is not running.
The battery will discharge and the
ignition could be damaged.

(c) Overdrive switch
You can select either fourth gear (with
overdrive off) or fifth gear (with overdrive
on) by pushing this switch.
To turn the overdrive off, push the switch.
The “O/D OFF” indicator light should come
on. To turn the overdrive on again, push
the switch again. The “O/D OFF” indicator
light should go off.
Always drive your vehicle with the over-
drive on for better fuel economy and
quieter driving.
If the engine is turned off when the over-
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
To use engine braking, you can downshift
the transmission as follows:
Push the overdrive switch. The “O/D
OFF” indicator light will come on and
the transmission will downshift to third
gear.
Shift into the “3” position. The trans-
mission will downshift to third gear
when the vehicle speed drops down to
or lower than the following speed, and
stronger engine braking will be en-
abled. Tw o −wheel drive models

slippery surface. Abrupt shifting
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.

 Do not continue hill climbing or
hard towing for a long time in the
“3”, “2” or “L” position. This may
cause severe automatic transmis-
sion damage from overheating. To
prevent such damage, “D” position
should be used in hill climbing or
hard towing.(g) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the selector lever to the
“R” position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.
(h) Parking
1. Bring the vehicle to a complete stop.
2. With the brake pedal pressed down, fully depress the parking brake pedal
to apply the parking brake securely.
3. With the brake pedal pressed down, shift the selector lever to the “P” posi-
tion.
CAUTION
Never attempt to move the selector
lever into “P” position under any cir-
cumstances while the vehicle is mov-
ing. Serious mechanical damage and
loss of vehicle control may result.
(i) Good driving practice
If the transmission repeatedly shifts up
and down between fourth gear and ov-
erdrive when climbing a gentle slope,
the overdrive should be turned off. Be
sure to turn the switch on immediately
afterward.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use overdrive.
CAUTION
Always keep your foot on the brake
pedal while stopped with the engine
running. This prevents the vehicle
from creeping.
NOTICE
Always use the brake pedal or the
parking brake to hold the vehicle on
an upgrade. Do not attempt to hold
the vehicle using the accelerator ped-
al, as this can cause the transmission
to overheat.
