(d) 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.
(e) 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 will not go off even after the
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, auto-
matic transmission electrical system or
warning light system itself.
Contact your Toyota dealer as soon as
possible to service the vehicle.
Emissions Inspection and Maintenance
(I/M) programs
Your vehicle may not pass a state
emission inspection if the malfunction
indicator lamp remains on. Contact your
Toyota dealer to check your vehicle’s
emission control system and OBD
(OnBoard Diagnostics) system before
taking your vehicle for the inspection.
For details, see “Emissions Inspection and
Maintenance (I/M) programs” in Section 6. (f) 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.
(g) 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.
(h) “ABS” Warning Light
The light comes on when the ignition key
is turned to the “ON” position. If the anti
lock brake system and the brake assist
system works pr operly, the light turns off
after a few seconds. Thereafter, if the
system malfunctions, the light comes on
again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
antilock brake system, the brake assist
system, the traction control system and
vehicle skid control system do not oper-
ate, but the brake system still operates
conventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
antilock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces. 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 “ON” posi-
tion, or remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
(i) Open Door Warning Light
This light remains on until all the doors
are completely closed.
(j) Open Power Sliding Door Warning Light and Buzzer
This light comes on if the power sliding
door is not completely closed with the
ignition key in the “ON” position.
If you forcibly close the power sliding door
by hand when the ignition key is in the
“ON” position, the open power sliding door
warning light may stay on. In this case,
try opening and closing the power sliding
door again by hand slowly, or use one of
the “DOOR L”, “DOOR R” or “PWR
DOOR” switches inside the vehicle or
“POWER DOOR”, “DPWR DOOR” or “P
PWR DOOR” switches of the wireless re-
mote control transmitter.
If you shift out of “P” when the power
sliding door is opened or in the process
of closing with the power sliding door sys-
tem on, a buzzer will sound and the open
power sliding door warning light will flash.
This is a warning that the sliding door is
not completely closed.

(k) SRS Warning Light
This light will come on when the igni-
tion key is turned to the “ACC” or
“ON” position. After about 6 seconds,
the light will go off. This means the
system of the airbag and front seat belt
pretensioners are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, side airbag sensor, front seat belt
pretensioner assemblies, inflators, warning
light, interconnecting 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 or flashes while
driving. (l) Vehicle Skid Control System/Traction
Control System Warning Light
This light warns that there is a problem
somewhere in the vehicle skid control sys-
tem or traction control system.
The light will come on when the ignition
key is turned to “ON” and will go off after
a few seconds.
If the light comes on while driving, the
system does not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.
In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition key is turned to “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing. (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 Section 73.)
(n) Low Tire Pressure Warning Light
This light warns that the tire pressure of
any one of the tires is critically reduced.
The light comes on when the ignition key
is turned to the “ON” position. It goes off
after a few seconds. This indicates that
the low tire pressure warning system is
functioning properly.
If the light comes on while driving, adjust
tire pressure to the specified level. (See
“Tires” in Section 8.) After the tire pres-
sure is adjusted, the light should go off
after driving at about more than 30 km/h
(19 mph) for some time. If the light still
remains, have the low tire pressure warn-
ing system checked at your Toyota dealer.
(o) 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”

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.
(c) 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 overdrive
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.
(d) 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 “2” position. The trans-
mission will downshift to second gear
when the vehicle speed drops down to
or lower than 112 km/h (69 mph), and
stronger engine braking will be en-
abled.
Shift into the “L” position. The trans-
mission will downshift to first gear
when the vehicle speed drops down to
or lower than 58 km/h (36 mph), and
maximum engine braking will be en-
abled.
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.
