Before driving
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.
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.
■ 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, front seat belt pretensioner assemblies, inflators, interconnecting wir-
ing and power sources. ( P. 505)
■ 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 windshield may crack.

When to contact your Toyota dealer
In the following cases, contact your Toyota dealer as soon as possible. Do
not disconnect the battery cables before contacting your Toyota dealer.
●Any of the SRS airbags have been inflated.
●The front of the vehicle is damaged or
deformed, or was involved in an acci-
dent that was not severe enough to
cause the SRS airbags to inflate.
● A portion of a door is damaged or
deformed, or the vehicle was involved
in an accident that was not severe
enough to cause the SRS side airbags
and curtain shield airbags to inflate.
● The pad section of the steering wheel
or dashboard is scratched, cracked, or
otherwise damaged.
● The surface of the seats with the side
airbag is scratched, cracked or other-
wise damaged.
● The portion of the front pillars, rear pil-
lars or roof side rail garnishes (padding)
containing the curtain shield airbags
inside is scratched, cracked or other-
wise damaged.

CAUTION
■SRS airbag precautions
Observe the following precautions regarding the airbags.
Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts
properly.
The SRS airbags are supplemental devices to be used with the seat belts.
● The SRS driver airbag deploys with considerable force, and can cause
death or serious injury especially if the driver is very close to the airbag.
The National Highway Traffic Safety Administration (“NHTSA”) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm)
of inflation, placing yourself 10 in. (250 mm) from your driver airbag pro-
vides you with a clear margin of safety. This distance is measured from the
center of the steering wheel to your breastbone. If you sit less than 10 in.
(250 mm) away now, you can change your driving position in several
ways:
• Move your seat to the rear as far as you can while still reaching the pedals comfortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many drivers can achieve the 10 in.
(250 mm) distance, even with the driver seat all the way forward, sim-
ply by reclining the back of the seat somewhat. If reclining the back of
your seat makes it hard to see the road, raise yourself using a firm,
non-slippery cushion, or raise the seat if your vehicle has that feature\
.
• If your steering wheel is adjustable, tilt it downward. This points the air- bag toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while
still maintaining control of the foot pedals, steering wheel, and your view of
the instrument panel controls.

SRS airbag precautions
●Do not use seat accessories which cover the parts where the SRS side
airbags inflate as they may interf ere with inflation of the airbags.
● Do not strike or apply significant levels of force to the area of the SRS air-
bag components ( P. 118).
Doing so can cause the SRS airbags to malfunction.
● Do not attach anything to or lean any-
thing against areas such as the dash-
board or steering wheel pad.
These items can become projectiles
when SRS driver and front passenger
airbags deploy.
● Do not attach anything to areas such as
the door, windshield glass, side door
glass, front or side pillars, roof side rail
or assist grip.
● Do not hang coat hangers or other hard
objects on the coat hooks. All of these
items could become projectiles and
seriously injure or kill you, should the
SRS curtain shield airbag deploy.

128 1-7. Safety information
CAUTION
■SRS airbag precautions
●Do not touch any of the component parts immediately after the SRS air-
bags have deployed (inflated) as they may be hot.
● If breathing becomes difficult after the SRS airbag has deployed, open a
door or window to allow fresh air in, or leave the vehicle if it is safe to do
so. Wash off any residue as soon as possible to prevent skin irritation.
● If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garnishes, are damaged or cracked, have
them replaced by your Toyota dealer.
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications
without consulting your Toyota dealer.
The SRS airbags may malfunction or deploy (inflate) accidentally, causing
death or serious injury.
● Installation, removal, disassembly and repair of the SRS airbags.
● Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, side and rear
pillars or roof side rails.
● Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment.
● Installation of snow plows, winches, etc. to the front grille (bull bars, kan-
garoo bar etc.).
● Modifications to the vehicle's suspension system.
● Installation of electronic devices such as mobile two-way radios or CD
players.
● Modifications to your vehicle for a person with a physical disability.

When driving
CAUTION
●
Do not drive the vehicle over or st op the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. This may
cause a fire if there is any flammable material nearby.
● Do not let the vehicle roll backwards while the shift lever is in a driving
position, or roll forward while the shift lever is in R. Doing so may cause
the engine to stall or lead to poor brake and steering performance, result-
ing in an accident or damage to the vehicle.
● If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the back door is closed. Large amounts of exhaust in the vehi-
cle can cause driver drowsiness and an accident, resulting in death or a
serious health hazard. Have the vehicle inspected by your Toyota dealer
immediately.
● Do not under any circumstances shift the shift lever to P or R while the
vehicle is moving. Doing so can cause significant damage to the transmis-
sion system and may result in a loss of vehicle control.
● Do not shift the shift lever to N while the vehicle is moving. Doing so may
cause insufficient engine braking and lead to an accident.
● Do not turn the engine off while driving. The power steering and brake
booster systems will not operate properly if the engine is not running.
● Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill. Using the brakes continuously may cause the brakes to
overheat and lose effectiveness. ( P. 170)
● When stopped on an inclined surface, use the brake pedal and parking
brake to prevent the vehicle from rolling backward or forward and causing
an accident.
● Do not adjust the position of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving. Doing so may result in a loss of
vehicle control that can cause accidents that may result in death or serious
injury.
● Always check that all passengers' arms, heads or other parts of their bod-
ies are not outside the vehicle, as this may result in death or serious injury.
● Do not drive the vehicle off-road.
This is not a AWD vehicle designed for real off-road driving. Proceed with
all due caution if it becomes unavoidable to drive off-road.

164 2-1. Driving procedures
CAUTION
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, you may accidentally move the shift
lever or depress the accelerator pedal, which could cause an accident or fire
due to engine overheating. Additionally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may collect and enter the vehicle, leadin\
g to
death or a serious health hazard.
■ When braking the vehicle
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and may cause one
side of the vehicle to brake differently than the other side. Also the parking
brake may not securely hold the vehicle.
● If the power brake assist function does not operate, do not follow other
vehicles closely and avoid downhills or sharp turns that require braking.
In this case, braking is still possible, but it will require more force on the
pedal than usual. Braking distance may also increase.
● Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
● The brake system consists of 2 individual hydraulic systems: If one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and braking distance
becomes longer.
Do not drive your vehicle with only a single brake system. Have your
brakes fixed immediately.
■ If the vehicle becomes stu ck or bogged (AWD models)
Do not spin the wheels recklessly when any of the tires is up in the air, or
stuck in sand or mud, etc. This may damage the drive system components
or propel the vehicle forward (or in another direction) and cause an accident.
