SEATS, SEAT BELTS, STEERING WHEEL AND MIRRORS35
The driver ’s seat belt pretensioner is
designed to be activated in response to
a severe frontal impact.
When the airbag sensor detects the shock
of a severe frontal impact, the driver ’s
seat belt is quickly drawn back in by the
retractor so that the belt snugly restrains
the driver.
Collisionsoccurring at certain speeds and
angles may cause the seat belt preten-
sioner and SRS airbag not to operate all
together.This indicator comes on when the en-
gine switch is turned to the “ON” posi-
tion. It goes off after about 6 seconds.
This means the driver ’s seat belt pre-
tensioner is operating properly.
This warning light system monitors the
airbag sensor assembly, airbag sensor,
driver ’s seat belt pretensioner assembly,
inflator, interconnecting wiring and power
sources. (For details, see “Service remind-
er indicators and warning buzzer” on page
73 in Section 1−5.)

—Driver’s seat belt
pretensioner

36SEATS, SEAT BELTS, STEERING WHEEL AND MIRRORS
The driver ’s seat belt pretensionersystem
mainly consists of the following compo-
nents and their locations are shown in the
illustration.
1. SRS warning light
2. Airbag sensor
3. Driver ’s seat belt pretensioner assem-
bly
4. Airbag sensor assembly
The driver ’s seat belt pretensioner is con-
trolled by the airbag sensor assembly. The
airbag sensor assembly consists of a saf-
ing sensor and airbag sensor.
When the driver ’s seat belt pretensioner is
activated, an operating noise may be
heard and a small amount of smoke−like
gas may be released. This gas is harm-
less and does not indicate that a fire is
occurring.
Once the driver ’s seat belt pretensioner
has been activated, the seat belt retractor
remains locked.
If the vehicle is involved in multiple colli-
sions, the pretensioner will activate for the
first collision, but will not activate for the
second or subsequent collisions.
CAUTION
Observe the following precautions to
reduce the risk of injury in the event
of sudden braking or an accident.
Failure to do so may cause death or
serious injury.
DIf the pretensioner has activated,
the SRS warning light will come on.
In that case, the seat belt cannot
be used again and must be re-
placed at any authorized Toyota
dealer or repairer, or another duly
qualified and equipped professional.
DDo not modify, remove, strike or
open the seat belt pretensioner as-
semblies, airbag sensor or sur-
rounding area or wiring. Consult
any authorized Toyota dealer or re-
pairer, or another duly qualified and
equipped professional about any re-
pair and modification.

SEATS, SEAT BELTS, STEERING WHEEL AND MIRRORS39
This indicator comes on when the en-
gine switch is turned to the “ON” posi-
tion. It goes off after about 6 seconds.
This means the SRS airbag is operating
properly.
This warning light system monitors the
airbag sensor assembly, airbag sensor,
driver ’s seat belt pretensioner assembly,
inflator, interconnecting wiring and power
sources. (For details, see “Service
reminder indicators and warning buzzer”
on page 73 in Section 1−5.)The SRS airbag system is designed to
activate in response to a severe frontal
impact within the shaded area between
the arrows in the illustration.
The SRS airbag will deploy in the event
of an impact that exceeds the set thresh-
old level (the level of force corresponding
to an approximately 20−30 km/h [12−18
mph] frontal collision with a fixed wall that
does not move or deform).
If the severity of the impact is below the
above threshold level, the SRS airbag
may not deploy.
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 it is involved in an underride
collision (e.g. a collision in which the nose
of the vehicle “underrides”, or goes under,
the bed of a truck, etc.).
It is possible that in some collisions at the
lower zone of airbag sensor detection and
activation the SRS airbag and seat belt
pretensioner will not operate all together.
For the safety of all occupants, always
wear your seat belts properly.

GAUGES, METERS AND SERVICE REMINDER INDICATORS77
(g) “ABS” Warning Light
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 systemdoes not operate,
but the brake system stilloperates con-
ventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti−lock brake systemdoes 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 any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional, as soon as possible to
service the vehicle.
DThe light does not come on when the
engine switch is turned to the “ON”
position, or the light remains on.
DThe light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
(h) SRS Warning Light
This light will come on when the engine
switch is turned to the “ON” position.
After about 6 seconds, the light will go
off. This means the systems of the air-
bag and driver ’s seat belt pretensioner
are operating properly.
This warning light system monitors the
airbag sensor assembly, airbag sensor,
driver ’s seat belt pretensioner assembly,
inflator, interconnecting wiring and power
sources.If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact any authorized Toyota
dealer or repairer, or another duly quali-
fied and equipped professional, as soon
as possible to service the vehicle.
DThe light does not come on when the
engine switch is turned to the “ON”
position or remains on for more than
6 seconds or flashes.
DThe light comes on or starts flashing
while driving.
(i) DPF (Diesel Particulate Filter) Sys-
tem Indicator Light
If the deposit builds up in the filter, the
indicator light on the instrument cluster
will come on when the engine switch is
turned on. The deposit built up in the filter
needs to be regenerated. For details, see
“DPF system” onpage 110 in Section 2.
If you do not perform regeneration and
continue to drive for a while with the indi-
cator light on, the light will begin to flash.
CAUTION
Continuing to drive with the light
flashing will cause the malfunction in-
dicator light to come on. In this
event, damage may be caused to the
vehicle or an accident may occur. If
the malfunction indicator light comes
on, have your vehicle checked by any
authorized Toyota dealer or repairer,
or another duly qualified and
equipped professional immediately.

(b) Starting the engine

STARTING AND DRIVING127
Instruments and controls.Especially
make sure the service reminder indicators,
instrument lights, and defroster are work-
ing.
Brakes.Make sure the pedal has enough
clearance.
Spare fuses.Make sure you have spare
fuses. They should cover all the amperage
ratings designated on the fuse box lid.
In the engine compartment
Coolant level.Make sure the coolant lev-
el is correct. (See page 190 in Section
7−2 for instructions.)
Wiring.Look for damaged, loose, or dis-
connected wires.
Fuel lines.Check the lines for leaks or
loose connections.
AFTER STARTING THE ENGINE
Exhaust system.If you notice any
change in the sound of the exhaust or
smell exhaust fumes, have the cause lo-
cated and corrected immediately. (See
“Engine exhaust cautions” on page 114 in
Section 2.)
Engine oil level.Stop the engine and
check the dipstick with the vehicle parked
on a level spot. (See page 188 in Section
7−2 for instructions.)
WHILE DRIVING
Instruments.Make sure the speedometer
and gauges are working.
Brakes.In a safe place, check that the
brakes do not pull to one side when ap-
plied.
Anything unusual?Look for loose parts
and leaks. Listen for abnormal noises.
If everything looks O.K., set your mind at
ease and enjoy your trip!DAlways slow down in gusty crosswinds.
This will allow you much better control.
DDrive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharp−edged objects and
other road hazards. Failure to do so
can lead to severe tire damage such
as a tire burst.
Drive slowly when passing over bumps
or travelling on abumpy road. Other-
wise, the impact could cause severe
damage to the tires and/or wheels.
DWhen parking on a hill, turn the front
wheels until they touch the curb so
that the vehicle will not roll. Apply the
parking brake, and place the transmis-
sion in first or reverse. If necessary,
block the wheels.
DWashing your vehicle or driving through
deep water may get the brakes wet. To
see whether they are wet, check that
there is no traffic near you, and then
press the pedal lightly. If you do not
feel a normal braking force, the brakes
are probably wet. To dry them, drive
the vehicle cautiously while lightly
pressing the brake pedal with the park-
ing brake applied. If they still do not
work safely, pull to the side of the road
and call any authorized Toyota dealer
or repairer, or another duly qualified
and equipped professional, for assis-
tance.
CAUTION
DBefore driving off, make sure the
parking brake is fully released and
the parking brake reminder light is
off.
DDo not leave your vehicle unat-
tended while the engine is running.
DDo not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
