Accessories, spare parts andmodification of your Toyota
A wide variety of non −genuine spare parts and accesso-
ries for Toyota vehicles are currently available in the
market. You should know that Toyota does not warrant
these products and is not responsible for their perfor-
mance, repair, or replacement, or for any damage they
may cause to, or adverse effect they may have on,
your Toyota vehicle.
This vehicle should not be modified with non −genuine
Toyota products. Modification with non −genuine Toyota
products could affect its performance, safety or durabili-
ty, and may even violate governmental regulations. In
addition, damage or performance problems resulting from
the modification may not be covered under warranty.
Installation of a mobile twoway radio system
As the installation of a mobile two −way radio system in
your vehicle could affect electronic systems such as
multiport fuel injection system/sequential multiport fuel
injection system, electronic throttle control system,
cruise control system, anti −lock brake system, active
traction control system, vehicle stability control system,
active height control suspension system, skyhook TEMS,
SRS airbag system and seat belt pretensioner system,
be sure to check with your Toyota dealer for precaution-
ary measures or special instructions regarding installa-
tion.

The seat belt pretensioner system con-
sists mainly of the following components,
and their locations are shown in the il-
lustration.1. Front airbag sensors
2. SRS warning light
3. Seat belt pretensioner assemblies
4. Airbag sensor assembly
The seat belt pretensioners are controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor. When the seat belt pretensioners are acti-
vated, an operating noise may be heard
and a small amount of non
−toxic gas may
be released. This does not indicate that
a fire is occurring. This gas is normally
harmless.
Once the seat belt pretensioners have
been activated, the seat belt retractors
remain locked.
CAUTION
Do not modify, remove, strike or
open the seat belt pretensioner as-
semblies, airbag sensor or sur-
rounding area or wiring. Failure to
follow these instructions may pre-
vent the seat belt pretensioners
from activating correctly, cause sud-
den operation of the system or dis-
able the system, which could result
in death or serious injury.
Do not use tires or wheels other
than the manufacturer ’s recom-
mended size. Such a use may cause
the curtain shield airbags and seat
belt pretensioners to inflate acci-
dentally, resulting in death or seri-
ous injury. For details, see “Check-
ing and replacing tires” on page
323.
Do not place luggage heavier than
specified on the roof luggage carri-
er. Such luggage may cause the
curtain shield airbags and seat belt
pretensioners to inflate accidentally,
resulting in death or serious injury.
For details, see “Roof luggage car-
rier” on page 218.
Do not modify or change the sus-
pension system. Such changes may
cause the curtain shield airbags to
inflate accidentally, resulting in
death or serious injury.
Failure to follow these instructions
can result in death or serious inju-
ries. Consult your Toyota dealer
about any repair and modification.

Do not attach a microphone or any
other device or object around the
area where the curtain shield airbag
activates such as on the windshield
glass, side door glass, front, center
and roof side garnish, roof interior
or assist grips. When the curtain
shield airbag inflates, the micro-
phone or other device or object will
be thrown away with great force or
the curtain shield airbag may not
activate correctly, resulting in death
or serious injury.
Do not hook a hanger, heavy or
sharp pointed objects on the coat
hook. If the curtain shield airbags
inflate, those items will be thrown
away with great force or the curtain
shield airbags may not activate cor-
rectly, resulting in death or serious
injury. When you hang clothes,
hang them on the coat hook direct-
ly.
Do not use seat accessories which
cover the parts where the side air-
bags inflate. Such accessories may
prevent the side airbags from acti-
vating correctly, causing death or
serious injury.

NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
 Do not continue driving with an
overheated engine. See “If your ve-
hicle overheats” on page 274.
Engine oil pressure gauge
Idling
Normal
driving
The engine oil pressure gauge indicates
engine oil pressure when the ignition
switch is on. Check it while driving to
make sure the needle is in the proper
range.
If the engine oil pressure should stay be-
low the normal range, pull off the road to
a safe place and stop the engine immedi-
ately. Call a Toyota dealer or qualified
repair shop for assistance.
Engine oil pressure may not build up
when the engine oil level is too low. The
engine oil pressure gauge is not designed
to indicate oil level, and the engine oil
level must be checked using the level
dipstick.
NOTICE
Do not drive the vehicle with the en-
gine oil pressure below the normal
range until the cause is fixed—it may
ruin the engine.

122
Vo l t m e t e r
The voltmeter tells whether the battery
is charged or discharged. Check it
while the engine is running—the needle
should always indicate as shown above.
If the needle reads below or above the
normal range while the engine is running,
it indicates the charging system needs im-
mediate repair.
However, it is normal for the needle to
drop below the normal range during en-
gine starting.
Tachometer
The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to prevent
engine over-revving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.
