Daytime Running Light  (DRL) system
(all models sold in Canada and some
models sold in U.S.A.)
The Daytime Running Light (DRL)  system
can make it easier for others to see the
front of your vehicle during the day. The
DRL system can be helpful in many differ-
ent driving conditions, but they can be
especially helpful in the short periods after
dawn and before sunset.
The DRL system will make the headlights
come on when:
The engine switch is on with the en-
gine running.
The knob is in the “OFF” position or
position 1.
The parking brake is  released.
To turn off the DRL system, twist the knob
to position 2 or turn the engine switch off.
High Low beams— For high beams, turn
the headlights on and push the lever away
from you (position 1). Pull the lever to-
ward you (position 2) for low beams.
The headlight high beam indicator light
(blue light) on the instrument panel will
tell you that the high beams are on.
Flashing the high beam headlights
(position 3)—Pull the lever all  the way
back. The high beam headlights  turn off
when you release the lever.
You can flash the high beam headlights
with the knob turned to “OFF”.TURN SIGNALS
To signal a turn, push the headlight/
turn signal lever up or down to position
1.
The engine switch must be in the “ON”
position.
The lever automatically returns after you
make a turn, but you may have to return
it by hand after you change lanes.
To signal a lane change, move the lever
up or down to the pressure point (position
2) and hold it.
If the turn signal indicator lights (green
lights) on the instrument panel flash faster
than normal, a front or rear turn signal
bulb is burned out.

Position 2 or 3 with the headlights on—
The lights automatically turn off after 30
seconds when all the side doors and back
door are closed with the engine switch in
the “ACC” or “LOCK” position.
If the lock switch of the wireless remote
control transmitter is pushed when all the
side doors and back door are already
locked, the lights automatically turn off
immediately.
The time before the headlights  turn off
can be changed. For details, contact your
Toyota dealer.
To turn them on again, turn the engine
switch to the “ON” position or actuate the
headlight switch.
If you are going to park  for over one
week, make sure the headlight switch is
off.
NOTICE
To prevent the battery from being dis-
charged, do not leave the lights on
for a long period when the engine is
not running.

(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.
If the vehicle speed rises above 5 km/h
(3 mph) with the parking brake applied, a
buzzer sounds.
When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
Have your vehicle checked at your
Toyota dealer in the following case:
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 initially
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 either of the following conditions
occurs, 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.
In  this case,  the brakes may not
work properly and your stopping
distance will become longer. De-
press 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.
(b) Driver’s Seat Belt Reminder Light
and Buzzer
The light and buzzer act as a reminder to
buckle up the driver’s seat belt.
Once the engine switch is turned to “ON”,
the reminder light flashes and buzzer
sounds if the driver ’s seat belt is not fas-
tened. Unless the driver fastens the belt,
the  light continues  flashing and  the buzzer
sounds for about 6 seconds.
If the vehicle speed rises above 20 km/h
(12 mph) with the seat belt unfastened,
the buzzer will sound for about 10 sec-
onds. Then, if the seat belt is still unfas-
tened, the buzzer will sound in a different
tone for 20 seconds. Even if the vehicle
speed drops below 20 km/h (12 mph), the
buzzer will continue to sound. To stop the
buzzer, fasten the seat belt. If the buzzer
still sounds, make sure the front passen-
ger ’s seat belt is fastened.

(h) “ABS” Warning Light
Vehicles without  the vehicle stability
control system—
The light comes on when the engine
switch is turned to the “ON” position. If
the anti−lock brake system works properly,
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
anti −lock brake system does not operate,
but the brake system still operates con-
ventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate
but the brake assist  system still operates.
In this case, 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 components moni-
tored by the warning light system. Con-
tact your Toyota dealer as soon as
possible to service the vehicle.
The light does not come on when the
engine switch is turned to the “ON”
position, 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 anti lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
Vehicles with  the vehicle stability con-
trol system—
The light comes on when the engine
switch is turned to the “ON” position. If
the anti −lock brake system and the brake
assist system works properly, 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
anti −lock brake system, the brake assist
system, the traction control system and
the vehicle stability control system do not
operate, but the brake system still oper-
ates conventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate
so that the wheels  could lock up during
a sudden braking or braking on slippery
road surfaces.

gine switch is turned to the “ON” posi-
tion. It goes off after about 6 seconds.
