8. Airbag sensor assembly
9. Knee airbag module for driver (airbag and inflator)
10. Airbag module for driver (airbag and inflator)
11. SRS warning light The airbag sensor assembly consists of a
safing sensor and airbag sensor.
The front airbag sensors constantly moni-
tor the forward deceleration of the vehicle.
If an impact results in a forward decelera-
tion beyond the designed threshold level,
the system triggers the airbag inflators. At
this time a chemical reaction in the infla-
tors very quickly fills the air bags with
non− toxic gas to help restrain the forward
motion of the occupants. The front airbags
then quickly deflate, so that there is no
obstruction of the driver ’s vision should it
be necessary to continue driving. When the airbags inflate, they produce a
loud noise and release some smoke and
residue along with non
−toxic gas. This
does not indicate a fire. This smoke may
remain inside the vehicle for some time,
and may cause some minor irritation to
the eyes, skin or breathing. Be sure to
wash off any residue as soon as possible
to prevent any potential skin irritation with
soap and water. If you can safely exit
from the vehicle, you should do so imme-
diately. Deployment of the airbags happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is desi
gned to reduce serious inju-
ries, primarily to the head and chest, it
may also cause other, less severe injuries
to the face, chest, arms and hands. These
are usually in the nature of minor burns
or abrasions and swelling, but the force of
a deploying airbag can cause more seri-
ous injuries, especially if an occupant’s
hands, arms, chest or head is in close
proximity to the airbag module at the time
of deployment. This is why it is important
for the occupant to; avoid placing any
object or part of the body between the
occupant and the airbag module; sit
straight and well back into the seat; wear
the available seat belt properly; and sit as
far as possible from the airbag module,
while still maintaining control of the ve-
hicle.
Parts of the airbag module (steering wheel
hub, lower portion of driver ’s side instru-
ment panel, airbag cover and inflator) may
be hot for several minutes after deploy-
ment, so do not touch! The airbags inflate
only once. The windshield may be dam-
aged by absorbing some of the force of
the inflating airbag.

(a) Brake System Warning Light andBuzzer
This light comes on in the following cases
when the ignition switch is set at ON.
When the parking brake is applied...
This light comes on for a few seconds
when the ignition switch is set at ON even
after the parking brake is released.
If the vehicle speed rises above 5 km/h
(3 mph) with the parking brake applied for
1 seconds or more, 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 cases:
The light does not come on even if the
parking brake is applied when the igni-
tion switch is set at ON.
The light does not come on even if the
ignition switch is set at 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 antilock
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 ignition switch is set at ON or
engine start, the reminder light flashes
and buzzer sounds if the driver ’s seat belt
is not fastened. Unless the driver fastens
the belt, the light continues flashing and
the buzzer sounds for about 6 seconds.
If the vehicle speed rises above 15 km/h
(9 mph) with the seat belt unfastened, the
buzzer will sound for about 10 seconds.
Then, if the seat belt is still unfastened,
the buzzer will sound in a different tone
for 20 seconds. Even if the vehicle speed
drops below 15 km/h (9 mph), the buzzer
will continue to sound. To stop the buzzer,
fasten the seat belt. If the buzzer still
sounds, make sure the front passenger ’s
seat belt is fastened.

151
(h) “ABS” Warning Light
Vehicles without vehicle stability control
system—
The light comes on with the ignition
switch is set at ON. If the anti−lock brake
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
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
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces. If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the components 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 switch is set at ON 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.
Vehicles with vehicle stability control
system—
The light comes on when the ignition
switch is set at ON. If the anti −lock brake
system and the brake assist system work
properly, the light turns off after a few
seconds. Thereafter, if the system mal-
functions, 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 and the brake as-
sist system do not operate, but the brake
system still operates conventi onally.
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.

152
If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the components 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 switch is set at ON 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 and Buzz- er
This light remains on until all the doors
are completely closed.
The buzzer also sounds once when any
of the doors is not completely closed at
the vehicle speed 5 km/h (3 mph) or
more. Stop the vehicle and close the door
completely.
(j) SRS Warning Light
This indicator comes on when the igni-
tion switch is set at ON. It goes off
after about 6 seconds. This means the
SRS airbags and seat belt pretensioners
are operating properly.
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, “AIRBAG ON” indi-
cator light, “AIRBAG OFF” indicator light,
front passenger ’s seat belt buckle switch,
seat belt pretensioner assemblies, inflat-
ors, interconnecting 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
ignition switch is set at ON or remains
on for more than 6 seconds.
The light comes on while driving.
The SRS warning light and “AIRBAG OFF”
indicator light will come on if there is a
malfunction in the front passenger occu-
pant classification system.

154
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 engine off with the odometer reading shown. (For details, see
“Odometer and two trip meters” on
page 143 in this Section.)
2. Turn the ignition switch is set at ON 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) Smart Key System Warning Light and Buzzer
The light and buzzer warn that there is a
problem somewhere in the operation of
the smart key system. See “Driving and
parking using smart key system” on page
300 in Section 3. (q) Dynamic Laser Cruise Control Mas-
ter Warning Light
This light warns that there is a problem
somewhere in the dynamic laser cruise
control system.
The light will come on when the ignition
switch is set at ON and go off after a few
seconds.
When the light comes on, the alarm
sounds and the warning code will appear
on the display. At this time, dynamic laser
cruise control is cancelled. For details,
see “Dynamic laser cruise control” on
page 179 in Section 1 −7.
(r) Key Reminder Buzzer (vehicles with key cylindertype ignition switch)
This buzzer act as a reminder to remove
the key when you open the driver’s door
with the engine off. CHECKING SERVICE REMINDER
INDICATORS (except the low fuel level
warning light)
1. Apply the parking brake.
2. Open one of the doors. The open door warning light should
come on.
3. Close the door. The open door warning light should go
off.
4. Set the ignition switch at ON, but do not start the engine.
All the service reminder indicators ex-
cept the open door warning light should
come on. The “ABS” and “VSC” warn-
ing lights, tire pressure warning light,
low windshield washer fluid level warn-
ing light, automatic headlight leveling
system warning light, engine oil re-
placement reminder light and dynamic
laser cruise master warning light go off
after a few seconds. The SRS warning
light goes off after about 6 seconds.
(slip indicator light and “READY” [dy-
namic laser cruise ready mode] indica-
tor light also come on and go off after
a few seconds. Front passenger occu-
pant classification indicator lights also
come on and go off after about 4 sec-
onds.)

182
This system operates by detecting pri-
marily the reflectors of the vehicle
ahead. The distance may not be accu-
rately or absolutely detected in the fol-
lowing cases:
The vehicle ahead has higher ground
clearance, which means that the
placement of the reflectors is in a
higher position.
The rear section of the vehicle ahead
is extremely dirty.
The vehicle ahead or other vehicles
around you are flinging up water or
snow.
Excessive exhaust gas (black smoke)
is coming from the vehicle ahead or
other vehicles around you, obscuring
your front view.
There is an obstruction (protective
film, sticker, etc.) on the reflectors
on the vehicle ahead, or reflectors
are not installed on the vehicle
ahead or are damaged.
Heavy luggage in the luggage
compartment or rear seats is caus-
ing the nose of your vehicle to tilt
up.
CAUTION
To avoid accidents, always keep the
laser radar sensor glass clean and
never allow it to be covered with
icicle or any substance, so it can de-
tect the vehicle in front. (See “LASER
RADAR SENSOR” on page 189.)
CAUTION
Do not rely excessively on dynamic
laser cruise control. Observe the fol-
lowing precautions in order to avoid
serious injury or death:
Under certain conditions where the
vehicle in front slows drastically, or
is stopped, the dynamic laser cruise
control will neither warn you nor
decelerate. You must depress the
brake pedal to slow down, ensuring
collision avoidance or that suffi-
cient vehicletovehicle distance is
maintained.
Do not use dynamic laser cruise
control in the following conditions:
In bad weather (such as rain, fog,
snow, sandstorms or direct sun-
light, or when raindrops or snow-
flakes get on the laser radar sensor
glass), the vehicletovehicle dis-
tance will not be measured accura-
tely.
When using the windshield wipers
at high or low speeds the dynamic
laser radar cruise control turns off.

TONE AND BALANCE
For details about your system’s tone and
balance controls, see the description of
your own system.
Type 1 and type 2 audio systems utilize
FOCUS and TruBass  audio enhance-
ment technologies, under license from
SRS Labs, Inc., in all mode except AM
radio mode.
Tone
How good an audio program sounds to
you is largely determined by the mix of
the treble, midrange (type 3 only), and
bass levels. In fact, different kinds of mu-
sic and vocal programs usually sound bet-
ter with different mixes of treble, midrange
and bass.
Balance
A good balance of the left and right stereo
channels and of the front and rear sound
levels is also important.
Keep in mind that if you are listening to
a stereo recording or broadcast, changing
the right/left balance will increase the vol-
ume of one group of sounds while de-
creasing the volume of another. YOUR RADIO ANTENNA
Your vehicle has an antenna printed on
the inside of the rear window.
NOTICE
Putting a film (especially a conductive
or metallic film) on the rear wi
ndow
will noticeably reduce the sensitivity
of the radio.
YOUR AUDIO DISPLAY
The audio information is displayed on the
center display.

ANTILOCK BRAKE SYSTEM
The antilock brake system is designed
to automatically help prevent lockup of
the wheels during a sudden braking or
braking on slippery road surfaces. This
assists in providing directional stability
and steering performance of the vehicle
under these circumstances.
Effective way to press the ABS brake
pedal: When the anti −lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti −lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. This
will result in reduced braking performan-
ce.
The anti −lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).
Depressing the brake pedal on slippery
road surfaces such as on a manhole cov-
er, a steel plate at a construction site,
joints in a bridge, etc. on a rainy day
tends to activate the anti −lock brake sys-
tem. You may hear a click or motor sound in
the engine compartment for a few seconds
when the engine is started or just after
the vehicle is started. This means that the
anti
−lock brake system is in the self
check mode, and does not indicate a mal-
function.
When the antilock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
You may hear the anti −lock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the ve-
hicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.
At the end of the anti −lock brake sys-
tem activation, the brake pedal may
move a little forward.
CAUTION
Do not overestimate the antilock
brake system: Although the antilock
brake system assists in providing ve-
hicle control, it is still important to
drive with all due care and maintain
a moderate speed and safe distance
from the vehicle in front of you, be-
cause there are limits to the vehicle
stability and effectiveness of steering
wheel operation even with the anti
lock brake system on.
If tire grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the antilock brake system does not
provide vehicle control.
