Essential Safety Equipment
Constant Monitoring
The following components of the air bag systems are monitored by a
diagnostic system: • Crash sensors, and diagnostic module (SAS unit)
• Front air bag sensors
• Air bag modules
• Side crash sensors
• Air bag/Front seat belt pret ensioner system warning light
• Front seat belt pretensioners
• Related wiring
• Front passenger air bag d eactivation indicator light
• Front passenger occupant classification sensor
• Front passenger occupant classification module
The diagnostic module continuously monitors the system’s readin ess.
This begins when the ignition is switched ON and continues whil e the
vehicle is being driven.

2-4. Fuel and Emission

Before Driving
Fuel and Engine Exhaust Precautions
Vehicles with catalytic converters or oxygen sensors must use O NLY
UNLEADED FUEL, which will reduc e exhaust emissions and keep
spark plug fouling to a minimum.
This vehicle will perform best with fuel listed in the table.
*: U.S. federal law requires that octane ratings be posted on gas oline station
pumps.
Fuel with a rating lower than 87 octane (91 RON) could cause th e
emission control system to lose e ffectiveness. It could also cause
engine knocking and s erious engine damage.
Gasoline blended with oxygenates such as alcohol or ether com-
pounds are generally referred to as oxygenated fuels. The commo n
gasoline blend that can be used with your vehicle is ethanol bl ended
at no more than 10 %. Gasoline containing alcohol, such as etha nol or
methanol, may be marketed under the name “Gasohol”.
Vehicle damage and drivability problems resulting from the use of the
following may not be co vered by the warranty.
• Gasohol containing m ore than 10 % ethanol.
• Gasoline or gasohol containing methanol.
• Leaded fuel or leaded gasohol.
Fuel Requirements
FuelOctane Rating* (Anti-knock index)
Regular unleaded fuel87 [(R M)/2 method] or above (91 RON or above)
NOTICE
●USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic converter and oxygen se nsors and
will lead to deterioration of the emission control system and o r failures.
● This vehicle can only use oxygenated fuels containing no more t han 10 %
ethanol by volume. Damage to the vehicle may occur when ethanol
exceeds this recommendation, or if the gasoline contains any me thanol.
Stop using gasohol of any kind if your vehicle engine is performing poorly.
● Never add fuel system additives, otherwise the emission control system
could be damaged. Consult your Toyota dealer for details.

When Driving
The light illuminates continuously
when the engine coolant tempera-
ture is low and turns off after the
engine is warm.
If the low engine coolant tempera-
ture indicator light remains illumi-
nated after the engine has been
sufficiently warmed up, the tem-
perature sensor could have a mal-
function. Consult your Toyota
dealer.

When Driving
When the lights are turned on, the
lights-on indicator light in the com-
bination meter turns on.
■Auto-light control (if equipped)
When the headlight switch is in the position and the ignition is
switched ON, the light sensor senses the surrounding lightness or
darkness and automatical ly turns the headlights, other exterior
lights and dashboard illumination on or off.
■ Headlights
●If the light switch is left on, the lights will automatically switch off approxi-
mately 30 seconds after switching the ignition off.
The time setting can be changed.
Refer to Customizable Features on P. 584.
● To prevent discharging the battery, do not leave the lights on while the
engine is off unless safety requires them.
■ Auto-light control
●The headlights, other exterior lights and dashboard illuminatio n may not turn
off immediately even if the surrounding area becomes well-lit because the
light sensor determines that it is night time if the surrounding area is contin-
uously dark for several minutes such as inside long tunnels, tr affic jams
inside tunnels, or in indoor parking lots.
In this case, the lights turn off if the light switch is turned to the position.
● If the headlight switch and the windshield wiper switch are in , and the
wipers are operated at low or high speed by the auto wiper cont rol for sev-
eral seconds, bad weather conditions are determined and the hea dlights
may be turned on.
● The dashboard illumination can be adjusted by rotating the knob in the
instrument cluster.
Also, the day/night mode can be changed by rotating the knob un til a beep
sound is heard.
To adjust the brightness of the dashboard illumination:
Refer to Dashboard Illumination on P. 158.
● The sensitivity of the auto-light control may be changed.
Refer to Customizable Features on P. 584.

NOTICE
●The light sensor also works as a rain sensor for the auto-wiper control.
Keep hands and scrapers clear of the windshield when the wiper lever is in
the position and the ignition is switched ON as fingers could be
pinched or the wipers and wiper blades could be damaged when th e wip-
ers activate automatically. If you are going to clean the windshield, be sure
the wipers are turned off completely when it is particularly te mpting to
leave the engine running. This is particularly important when clearing ice
and snow.
● Do not shade the light sensor by adher-
ing a sticker or a label on the wind-
shield. Otherwise the light sensor will
not operate correctly.

When Driving
●With auto-wiper control
Turn the wipers on by pressing
the lever up or down.
■Auto-wiper control
When the wiper lever is in the position, the rain sensor
senses the amount of rainfall on
the windshield and turns the wip-
ers on or off automatically
(off―intermittent―low speed―
high speed).
The sensitivity of the rain sensor
can be adjusted by turning the
switch on the wiper lever.
From the center position (normal), rotate the switch upward for higher
sensitivity (faster response) or rotate it downward for less sensitivity
(slower response).

3-4. Switches and Controls
●Switching the auto-wiper lever from the to the position while driv-
ing activates the windshield wipers once, after which they oper ate according
to the rainfall amount.
● The auto-wiper control may not operate when the rain sensor tem perature is
about -10 °C (14 °F) or lower, or about 85 °C (185 °F) or higher.
● If the windshield is coated with water repellent, the rain sens or may not be
able to sense the amount of rainfall correctly and the auto-wip er control may
not operate properly.
NOTICE
● When the wiper lever is in the position and the ignition is sw itched
ON, the wipers may move automatically in the following cases:
• If the windshield above the rain sensor is touched or wiped wi th a cloth.
• If the windshield is struck with a hand or other object from e ither outside
or inside the vehicle.
Keep hands and scrapers clear of the windshield when the wiper lever is
in the position and the ignition is switched ON as fingers cou ld be
pinched or the wipers and wiper blades damaged when the wipers acti-
vate automatically. If you are going to clean the windshield, be sure the
wipers are turned off completely (when it is most likely that t he engine is
left running) this is particularly important when clearing ice and snow.
●Do not shade the rain sensor by adher-
ing a sticker or a label on the wind-
shield. Otherwise the rain sensor will
not operate correctly.

Active Safety System
◆Pre-Crash Safety Technology
Pre-crash safety technology is designed to assist the driver in
averting collisions or reduce their severity in situations where they
cannot be avoided.
● Collision damage reducti on in low vehicle speed range
Forward driving:
Smart City Brake Support (SCBS) ( P. 217)
◆Sensor
● Laser sensor
The laser sensor emits a near-infrared laser beam and receives
the beam reflected off the refl ective surface of a vehicle or
obstruction in front, and the det ected beam is then used for me a-
surement. The laser sensor is used for the Smart City Brake
Support (SCBS) system.
The laser sensor is installed at the top of the windshield near the
rearview mirror.
Refer to Laser Sensor on P. 223.

When Driving
Smart City Brake Support (SCBS)
The Smart City Brake Support (SCBS) system is designed to
reduce damage in the event of a c ollision by operating the brake
control (SCBS brake) when the system’s laser sensor detects a
vehicle ahead and determines that a collision with a vehicle
ahead is unavoidable. It may also be possible to avoid a colli-
sion if the relative speed between your vehicle and a vehicle
ahead is less than about 12 mph (20 km/h).
In addition, when the driver depresses the brake pedal while th e
system is in the operation range at about 2 to 18 mph (4 to
30 km/h), the brakes are applied firmly and quickly to assist.
