(a) Brake System Warning Light
This light has the following functions:
Parking brake reminder
If this light is on, make sure the parking
brake is fully released. The light should
go off.
Low brake fluid level warning
If this light comes on and stays on while
you are driving, slow down and pull off
the road. Then stop the vehicle carefully.
Remember that stopping distance pedal
effort may be increased. There may be a
problem somewhere in the brake system.
Check the fluid level of the see-through
reservoir.
To make sure the parking brake has not
caused the warning light to come on,
check to see that the parking brake is
fully released.
If the brake fluid level is low...
At a safe place, test your brakes by start-
ing and stopping.
If you judge that the brakes still work
adequately, drive cautiously to your
nearest dealer or shop for repairs.
If the brakes are not working, have the
vehicle towed in for repairs. (For tow-
ing information, see Part 4.)
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
If the brake fluid level is correct...
Have the warning system checked by your
Toyota dealer.
(b) Seat Belt Reminder Light and Buzz-
er
Once the ignition key is turned to ”ON” or
”START”, the reminder light and buzzer
come on if the driver’s seat belt is not
fastened. Unless the driver fastens the
belt, the light stays on and the buzzer
stops after about 4 to 8 seconds.
(c) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system. The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.
NOTICE
Do not continue driving if the engine
drive belt is broken or loose.
(d) Low 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.

T100(U)63
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.
(e) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.
(f) Malfunction indicator lamp
This lamp comes on in the following
cases.
a. The fuel tank is completely empty. (See
”Fuel gauge” in Chapter 1−5 for instruc-
tions.)
b. The fuel tank cap is not tightened se-
curely. (See ”Fuel tank cap” in Chapter1 −2 for instructions.)
c. There is a problem somewhere in your
engine or automatic transmission electrical
system. If it comes on while you are driving in
case b, have your vehicle checked/re-
paired by your Toyota dealer as soon as
possible.
(g) ”ABS” Warning Light
This light warns that there is a problem
somewhere in your anti-lock brake system.
If it comes on while you are driving, have
your vehicle checked by your Toyota dealer
as soon as possible.
The light will come on when the ignition
key is turned to the ”ON” position. After
about 3 seconds, the light will go off.
When the ”ABS” warning light is on (and
the brake system warning light is off), the
brake system operates conventionally but
anti
−lock brake system is not assisting
brake performance so that the wheels can
lock −up during sudden braking or braking
on slippery road surfaces.
(h) SRS Airbag Warning Light
This light will come on when the ignition
key is turned to the ”ACC” or ”ON” posi-
tion. After about 6 seconds, the light will
go off. This means the airbag system is
operating properly. The warning light system monitors the
front airbag sensors, center airbag sensor
assembly, inflator, warning light, intercon-
necting wiring and power sources.
If either of the following conditions occurs, this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as soon
as possible to service the vehicle.
The light does not come on when the
ignition key is turned to the ”ACC” or
”ON” position or remains on.
The light comes on while driving.
(i) Light Reminder Buzzer
This buzzer will sound if the driver ’s door
is opened while the ignition switch is
turned to the ”LOCK” position with the
headlight switch on. Removing the key will
not stop the buzzer as long as the head-
light switch is on.
(j) Key Reminder Buzzer
This buzzer reminds you to remove the
key when you open the driver’s door with
the ignition key in the ”ACC” or ”LOCK”
position.

(k) Unengaged ”Park” Warning Light
(vehicles with automatic transmis-
sion)
This light warns that the transmission
”Park” mechanism is not engaged. If the
four-wheel drive control is in the ”N” posi-
tion while the selector lever is in the ”P”
position, the transmission will disengage
and the wheels will not lock.
CAUTION
To restore the park function, shift the
four-wheel drive control out of ”N”,
or the vehicle can move.
(l) Automatic Transmission Fluid Tem- perature Warning Light
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. (m) Low Windshield Washer Fluid Level
Warning Light
The light warns that the windshield washer
fluid level is too low. Add washer fluid at
your earliest opportunity. (For instructions,
see ”Adding washer fluid” in Chapter 7 −3.)
CHECKING SERVICE REMINDER INDICA-
TORS (except the low fuel level warning
light and low windsield washer fluid
level warning light) 1. Apply the parking brake.
2. Turn the ignition key to ”ACC”. The SRS airbag warning light should
come on. It goes off after about 6 se-
conds.
3. Turn the ignition key to ”ON”, but do not start the engine.
All the service reminder indicators ex-
cept the SRS airbag warning light
should come on. The ”ABS” warning
light goes off after about 3 seconds.
If any service reminder indicator or warn-
ing buzzer does not function as described
above, either the bulb is burned out or the
circuit is in need of repair. Have it
checked by your Toyota dealer as soon as
possible.

Automatic transmission
Vehicles with cruise control–When the cruise control is being used, even
if you downshift the transmission by turning off the overdrive switch, engine
braking will not be applied because the cruise control is not cancelled. For ways to decrease the vehicle speed, see ”Cruise control” in this chapter.

T100(U)67
Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only shift out of ”P” position when the
brake pedal is depressed (with the ignition
switch in ”ON” position and selector lever
pulled toward you).
(a) Normal driving
1. Start the engine as instructed in ”How to start the engine” in Part 3. The
transmission must be in ”P” or ”N”.
2. With your foot holding down the brake pedal, shift the selector lever to ”D”.
In ”D” position, the automatic transmission
system will select the most suitable gear
for running conditions such as normal
cruising, hill climbing, hard towing, etc.
Always turn the overdrive switch on for
better fuel economy and quieter driving.
Two-wheel drive models–If the engine
coolant temperature is low, the transmis-
sion will not shift into the overdrive gear
even with the overdrive switch on. Four-wheel drive models–If the engine
coolant temperature is low and the vehicle
is travelling at low speed or when the
four-wheel drive control lever is in ”L4”
(four-wheel drive, low range), the trans-
mission will not shift into the overdrive
gear even with the overdrive switch on.
(See ”Four-wheel drive system” in this
Chapter for information of the four-wheel
drive control lever.)
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.
(b) Using engine braking
To use engine braking, you can downshift
the transmission as follows: Turn off the overdrive switch. The ”O/D
OFF” indicator light will come on and
the transmission will downshift to the
third gear.
Shift into the ”2” position. The trans-
mission will downshift to the second
gear when the vehicle speed drops
down to or lower than the following
speed, and more powerful engine brak-
ing will be obtained.
Tw o −wheel drive models—
3RZ −FE engine.....112 km/h (70 mph)
5VZ −FE engine.....117 km/h (73 mph)
Four −wheel drive models—
—Four −wheel drive control lever
in ”H2” and ”H4”.....112 km/h (70 mph)
—Four −wheel drive control lever
in ”L4”.....38 km/h (24 mph)
Shift into the ”L” position. The trans-
mission will downshift to the first gear
When the vehicle speed drops down to
or lower than the following speed, and
maximum engine braking will be ap-
plied.
Tw o −wheel drive models—
3RZ −FE engine.....54 km/h (34 mph)
5VZ −FE engine.....56 km/h (35 mph)
Four −wheel drive models—
—Four −wheel drive control lever
in ”H2” and ”H4”.....54 km/h (34 mph)
—Four −wheel drive control lever
in ”L4”.....10 km/h (6 mph)

T100(U)

Vehicles with cruise control–When the
cruise control is being used, even if you
downshift the transmission by turning off
the overdrive switch, engine braking will
not be applied because the cruise control
is not cancelled. For ways to decrease
the vehicle speed, see ”Cruise control” in
this chapter.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
(c) Using ”2” and ”L” positions
The ”2” and ”L” positions are used for
strong engine braking as described pre-
viously.
With the selector lever in ”2” or ”L”, you
can start the vehicle in motion as with the
lever in ”D”.
With the selector lever in ”2”, the vehicle
will start in the first gear and automatical-
ly shift to the second gear.
With the selector lever in ”L”, the trans-
mission is engaged in the first gear.
NOTICE

Be careful not to overrev the en-
gine. Watch the tachometer to keep
engine rpm from going into the red
zone. The approxmate maximum al-
lowable speed for each position is
given below for your reference:
Two-wheel drive models—
”2” 100 km/h (62 mph)
”L” 55 km/h (34 mph)
Four-wheel drive models—
—Four-wheel drive control lever
in ”H2” and ”H4” ”2” 100 km/h (62 mph)
”L” 55 km/h (34 mph)
—Four-wheel drive control lever
in ”L4” ”2” 35 km/h (21 mph)
”L” 20 km/h (12 mph)
Do not continue hill climbing for a
long time in the ”2” or ”L” posi-
tion. This may cause severe auto-
matic transmission damage from
overheating. To prevent such dam-
age, use ”D” position for hill climb-
ing or hard towing.
(d) 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.
(e) Parking
1. Bring the vehicle to a complete stop. Pull the parking brake lever up fully to
securely apply the parking brake.
With the brake pedal pressed down,
shift the selector lever to the ”P” posi-
tion.
CAUTION
While the vehicle is moving, never
attempt to move the selector lever
into ”P” position under any circum-
stances. Serious mechanical damage
and loss of vehicle control may re-
sult.

T100(U)69
(f) Good driving practice
If the transmission is repeatedly up-
shifted and downshifted between third
gear and overdrive when climbing a
gentle slope, the overdrive switch
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
Do not hold the vehicle on an up-
grade with the accelerator pedal. It
can cause the transmission to over-
heat. Always use the brake pedal or
parking brake.
(g) Rocking your vehicle if stuck
CAUTION
To rock your vehicle if it becomes
stuck in snow, mud, sand, etc., first
check that there are no objects or
people around the vehicle. During the
rocking operation the vehicle may
suddenly move forward or backward
as it becomes unstuck, causing injury
or damage to nearby people or ob-
jects.
NOTICE
If you rock your vehicle, observe the
following precautions to prevent dam-
age to the transmission and other
parts. Do not depress the accelerator ped-
al while shifting the selector lever
or before the transmission is com-
pletely shifted to forward or reverse
gear.
Do not race the engine and avoid
spinning the wheels.
If your vehicle remains stuck after
rocking the vehicle several times,
consider other ways such as tow-
ing.

T100(U)

Manual transmission
The shift pattern is conventional as
shown above.
Press the clutch pedal down fully while
shifting, and then release it slowly. Do not
rest your foot on the pedal while driving,
because it will cause clutch trouble. And
do not use the clutch to hold the vehicle
when stopped on an uphill grade–use the
parking brake.
Recommended shifting speeds
The transmission is fully synchronized and
upshifting or downshifting is easy.
For the best compromise between fuel
economy and vehicle performance, you
should upshift or downshift at the following
speeds:

Upshifting too soon or downshifting too
late will cause lugging, and possibly ping-
ing. Regularly revving the engine to maxi-
mum speed in each gear will cause ex-
cessive engine wear and high fuel
consumption.
Maximum allowable speeds
To get on a highway or to pass slower
traffic, maximum acceleration may be nec-
essary. Make sure you observe the follow-
ing maximum allowable speeds in each
gear:
