(a) Brake System Warning Light andBuzzer
This light comes on in the following cases
when the engine switch is in the ON"
position.
When the parking brake is applied...
This light comes on for a few seconds
when the engine switch is turned to the
ON" position even after the parking brake
is released.
When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
When the hydraulic brake booster
fails...
If the hydraulic booster causes a problem
resulting in poor braking performance, the
warning light comes on and buzzer sounds
continuously. Have your vehicle checked at your
Toyota dealer in the following cases:
The light does not come on even if the
parking brake is applied when the en-
gine switch is in the ON" position.
The light does not come on even if the
engine switch is turned on with the
parking brake released.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If any of the following conditions oc-
curs, immediately stop your vehicle at
a safe place and contact your Toyota
dealer.
The light does not turn off even
after the parking brake is released
while the engine is running.
The warning buzzer comes on to-
gether with the warning light.
In either case, this can indicate that
the brakes may not work properly
and your stopping distance will be-
come longer. Depress the brake
pedal firmly and bring the vehicle
to an immediate stop.
The brake system warning light re-
mains on together with the ABS"
warning light.
In this case, not only the anti−lock
brake system will fail but also the
vehicle will become extremely un-
stable during braking.
Any of the following conditions may oc-
cur, but do not indicate the malfunc-
tion:
The light may stay on for about 60
seconds after the engine switch is
turned to the ON" position. It is nor-
mal if it turns off after a while.
Depressing the brake pedal repeatedly
may turn on the warning light and
buzzer. It is normal if the light turns off
and the buzzer stops sounding after a
few seconds.
You may hear a small sound in the
engine compartment after the engine is
started or the brake pedal is depressed
repeatedly. This is a pump pulsating
sound of the brake system, and it is
not a malfunction.

157
Either of the following conditions may
occur, but do not indicate a malfunc-
tion:
The light may stay on for about 60
seconds after the engine switch is
turned to the ON" position. It is nor-
mal if it turns off after a while.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
turns off after a few seconds.

Vehicle stability control system
Traction control system
(two−wheel drive models)
Active traction control system
(four−wheel drive models)
AUTO LSD" system
(two−wheel drive models)
Downhill assist control system

The light will come on when the engine
switch turned to ON", and will go off after
a few seconds. It is not a malfunction that the warning
light may stay on for 60 seconds after the
engine switch is turned to the ON" posi-
tion.
Depressing the brake pedal repeatedly
may turn on the lights. It is normal if they
go out after a few seconds.
If the light flashes while driving, the above
mentioned systems do not work. However,
as conventional braking operates when ap-
plied, there is no problem to continue your
driving.
In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the engine switch is turned to
ON".
The warning light remains on after the
engine switch is turned to ON".
The warning light flashes while driving.

This light remains on until all the side
doors and back door are completely
closed. (l) SRS Warning Light
This indicator comes on when the en-
gine switch is turned to the ON" posi-
tion. It goes off after about 6 seconds.
This means the SRS airbags and seat
belt pretensioners are operating proper-
ly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors, driv-
er ’s seat position sensor, driver ’s seat belt
buckle switch, front passenger occupant
classification system and indicator light,
front passenger ’s seat belt buckle switch,
seat belt pretensioner assemblies, inflat-
ors, RSCA OFF" indicator light, intercon-
necting wiring and power sources.
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Toyota dealer as soon as possible.
The light does not come on when the
engine switch is turned to the ON"
position or remains on for more than
6 seconds or flashes.
The light comes on or starts flashing
while driving.

dicator light will indicate OFF" if there is
a malfunction in the front passenger occu-
pant classification system.
(m) Automatic Transmission FluidTemperature Warning Light
(four−wheel 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.
NOTICE
Continued driving with the warning
light on may damage the automatic
transmission.
(n) Tire Pressure Warning Light
This light warns that the tire pressure of
one or more of your tires (including the
spare tire) is low. The light comes on
when the engine switch is turned to the
ON" position. It goes off after a few sec-
onds. This indicates that the tire pressure
warning system is functioning properly.
If the warning light comes on, stop your
vehicle in a safe place as soon as pos-
sible and check that the inflation pressure
of all tires (including the spare tire) is as
specified on the tire and loading informa-
tion label. (See Checking tire inflation
pressure" on page 441 in Section 7−2.)
The light should go off a few minutes after
the tire pressure is adjusted.
If the warning light comes on after blink-
ing for 1 minute, the tire pressure warning
system may be malfunctioning. Contact
your Toyota dealer.
For details, see Tire pressure warning
system" on page 197 in Section 1−7. (o) Low Windshield Washer Fluid Level
Warning Light (for vehicles sold in
Canada)

CY20008a
Your engine is fitted with iridium−tipped
spark plugs.
NOTICE
Use only iridium−tipped spark plugs.
Do not adjust gaps for engine perfor-
mance or smooth driveability.
This brake system has 2 independent hy-
draulic circuits. If either circuit should fail,
the other will still work. However, the ped-
al will be harder to press, and your stop-
ping distance will increase. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses brake fluid pres-
surized by the pump to power−assist the
brakes. If the brake booster fails during
driving, the brake system warning light
comes on and buzzer sounds continuous-
ly. In this case, the brakes may not work
properly. If they do not work well, depress
the brake pedal firmly. If the brake system
warning light comes on, immediately stop
your vehicle and contact your Toyota deal-
er.
It is not a malfunction that the brake sys-
tem warning light may stay on for 60 sec-
onds after the engine switch is turned to
the ON" position.Depressing the brake pedal repeatedly
may turn on the brake system warning
light and buzzer. It is normal if the light
turns off and the buzzer stops sounding
after a few seconds.
You may hear a small sound in the engine
compartment after the engine is started or
the brake pedal is depressed repeatedly.
This is a pump pulsating sound of the
brake system, and it is not a malfunction.
CAUTION
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your brake fluid
pressure reserve.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than nor-
mal. And your braking distance will
increase.

Driving in the rain
Driving on a slippery road surface
Drive carefully when it is raining, because
visibility will be reduced, the windows may
become fogged−up, and the road will be
slippery.
Drive carefully when it starts to rain,
because the road surface will be espe-
cially slippery.
Refrain from high speeds when driving
on an expressway in the rain, because
there may be a layer of water between
the tires and the road surface, prevent-
ing the steering and brakes from oper-
ating properly.
CAUTION
Sudden braking, acceleration and
steering when driving on a slippery
road surface may cause tire slip-
page and reduce your ability to
control the vehicle, resulting in an
accident.
Sudden changes in engine speed,
such as sudden engine braking,
may cause the vehicle to skid, re-
sulting in an accident.
After driving through a puddle,
lightly depress the brake pedal to
make sure that the brakes are func-
tioning properly. Wet brake pads
may prevent the brakes from func-
tioning properly. If the brakes on
only one side are wet and not func-
tioning properly, steering control
may be affected, resulting in an ac-
cident.
When encountering flooded roads
Do not drive on a road that has flooded
after heavy rain etc. Doing so may cause
serious damage to the vehicle.
NOTICE
Driving on a flooded road may cause
the engine to stall as well as cause
serious vehicle malfunctions such as
shorts in electrical components and
engine damage from water immersion.
In the event that you drive on a
flooded road and the vehicle is
flooded, be sure to have your Toyota
dealer check brake function, changes
in quantity and quality of oil and fluid
used for the engine, transmission,
transfer (4WD vehicles), differentials,
etc. and lubricant condition for the
propeller shaft, bearings and suspen-
sion joints (where possible) and the
function of all joints and bearings.
