Before driving
CAUTION
■Wearing a seat belt
●Do not recline the seat any more than necessary to achieve a proper seat-
ing position. The seat belt is most effective when the occupants are sitting
up straight and well back in the seats.
● Do not wear the shoulder belt under your arm.
● Always wear your seat belt low and snug across your hips.
■ Seat belt pretensioners
●Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the seat belt
pretensioner for the front passenger’s seat may not activate in the event of
a collision.
● If the pretensioner has activated, the seat belt becomes locked: it cannot
be further extended, nor will it return to the stowed position. The seat belt
cannot be used again and must be replaced at your Toyota dealer.
■ Child restraint lock function belt
Do not allow children to play with the child restraint lock function bel\
t.
■ Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate, or buckle to be
jammed in the door.
● Inspect the seat belt system periodically. Check for cuts, fraying, and loose
parts. Do not use a damaged seat belt until it is replaced. Damaged seat
belt cannot protect an occupant from death or serious injury.
● Ensure that the belt and tab are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact your Toyota
dealer.
● Replace the seat assembly, including the belts, if your vehicle has been
involved in a serious accident, even if there is no obvious damage.
● Do not attempt to install, remove, modify, disassemble or dispose of the
seat belts. Have any necessary repairs carried out by your Toyota dealer.
Inappropriate handling of the pretensioner may prevent it from operating
properly resulting in death or serious injury.

■To prevent sensor error (veh icles with auto anti-glare inside rear view
mirror)
Auto anti-glare inside rear view mirror
In automatic mode, sensors are used to detect the headlights of
vehicles behind and automatical ly reduces the reflected light.
Turns automatic mode ON/
OFF
The indicator comes on when
automatic mode is turned on.
The mirror will revert to the
automatic mode each time the
engine switch is turned on.
To ensure that the sensors operate prop-
erly, do not touch or cover them.

1-6. Theft deterrent system
Alarm (if equipped)
The system sounds the alarm and flashes lights when forcible entry
is detected.
■ Triggering of the alarm
The alarm is triggered in the following situations.
●A locked door is unlocked or opened in any way other than
using the wireless remote control door lock function or key.
The doors will lock again automatically.
● The hood is opened while t he vehicle is locked.
● Vehicles with the glass breakage sensor (if equipped): The
side windows are tapped or broken.
● The battery is reconnected.
■ Setting the alarm system
Close the doors and hood,
and lock all doors using the
wireless remote control or key.
The system will be set auto-
matically after 30 seconds.
The indicator changes from
being on to flashing when the
system is set.
■Deactivating or stopping the alarm
●Unlock the doors using the wire less remote control or key.
● Turn the engine switch to the ON position.
(The alarm will be deactivated or stopped after a few sec-
onds.)

1-7. Safety information
1
Before driving
Your vehicle is equipped with
ADVANCED AIRBAGS designed based
on US motor vehicle safety standards (FMVSS208). The airbag sys-
tem controls airbag deployment power for the driver and right front
passenger. The driver airbag system consists of the driver seat’s
position sensor etc. The front pass enger’s airbag system consists of
the front passenger occupant classification sensor etc.
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. The
airbag sensor assembly consists of a safing sensor and an airbag
sensor.
Front bench type seat: The SRS airbags are designed to protect the
driver and right front passenger, and they are not designed to protect
an occupant in the front center seating position.
In certain types of severe frontal or side impacts, the SRS airbag sys-
tem triggers the airbag inflators. A chemical reaction in the inflators
quickly fills the airbags with non-toxic gas to help rest rain the motion
of the occupants. Side airbags

■SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag
sensors, side and curtain shield airbag sensor assemblies, curtain shield air-
bag sensor assemblies, driver’s seat position sensor, driver’s seat belt
buckle switch, front passenger occupant classification system, AIR BAG ON
and AIR BAG OFF indicator lights, front passenger’s seat belt buckle switch,
passenger airbag off switch (Regular C ab models), front seat belt preten-
sioner assemblies, RSCA OFF indicator light, inflators, interconnecting wir-
ing and power sources. ( P. 546)
■ If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the front seats, and parts of the front and rear pillars and roof
side rail, may be hot for several minutes. The airbag itself may also be
hot.
● The front windshield may crack.
■ Operating conditions (front airbags)
● The SRS front airbags will deploy if the severity of the frontal impact is
above the designed threshold level, comparable to an approximate 15
mph (25 km/h) collision when the vehicle impacts straight into a fixed bar-
rier that does not move or deform.
However, this threshold velocity will be considerably higher if the vehicle
strikes an object, such as a parked vehicle or sign pole, which can move or
deform on impact, or if the vehicle is involved in an underride collision (e.g.
a collision in which the front of the vehicle “underrides”, or goes under, the
bed of a truck, etc.).
● It is possible that in some collisions where the forward deceleration of the
vehicle is very close to the designed threshold level, the SRS front air-
bags and the seat belt pretensioners may not activate together.
● The SRS front passenger airbag will not activate if there is no passenger
sitting in the right front passenger seat. However, the front passenger air-
bag may deploy if luggage is put in the seat, or the seat belt is fastened,
even if the seat is unoccupied. ( P. 131)

208 2-3. Operating the lights and wipers
■Daytime running light system (if equipped)
To make your vehicle more visible to other drivers, the front turn signal lights
turn on automatically whenever the engine is started and the parking brake
is released. Daytime running lights are not designed for use at night.
■ Headlight control sensor (vehicles wi th automatic light control system)
■ Automatic light off system
●When the headlights come on: The headlights and tail lights automati-
cally turn off after 30 seconds when all doors are closed with the engine
switch turned to the ACC or LOCK position. (The lights turn off immedi-
ately if the button on the wireless remote control is pressed after all
doors are locked.)
● When only the tail lights come on: The tail lights turn off automatically
with the engine switch turned to the ACC or LOCK position and the
driver’s door is opened.
Vehicles with automatic light control system: If any of the doors is kept open,
the lights automatically turn off after 20 minutes.
To turn the lights on again, turn the engine switch to the ON position, or turn
the headlight switch off once and then back to the or position.
■ Customization
●That can be configured at Toyota dealer (vehicles without multi-informa-
tion display)
Settings (automatic light off system) can be changed. (Customizable
features P. 633)
● It is possible to change the settings (vehicles with multi-information dis-
play) (Feature customization P. 200)
The sensor may not function properly if
an object is placed on the sensor, or any-
thing that blocks the sensor is affixed to
the windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.

When driving
Intuitive parking assist (if equipped)
The intuitive parking assist is designed to inform you of the approxi-
mate distance between your vehicle and an obstruction by indicator
and buzzer when parking the veh icle. This system uses sensors to
detect obstructions.
■ Sensor types
Back sensors
Rear corner sensors
Front corner sensors
■ Intuitive parking assist switch
Press the switch to turn on.
(To turn off, press the switch
again.)
When on, the buzzer sounds
to inform the driver that the
system is operational. At this
time, the indicator will come
on.
