The seat belt pretensionersystem con-
sists mainly of the following components
and their locations are shown in the il-
lustration.
1. SRS warning light
2. Airbag sensor assembly
3. Seat belt pretensioner assemblies
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.
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
severe 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.

STARTING AND DRIVING211
Before starting the engine, be sure to
follow the instructions in “(a) Before
cranking”.
Normal starting procedure
The multiport fuel injection system/sequen-
tial multiport fuel injection system in your
engine automatically controls the proper
air−fuel mixture for starting. You can start
a cold or hot engine as follows:
Multi−mode manual transmission:With
your foot off the accelerator pedal, turn
the engine switch to the “START” posi-
tion and crank the engine while depress-
ing the brake pedal. Release the key
when the engine starts. The engine can-
not be cranked if the shift lever is in a
position except “N” or the brake pedal
is not depressed.
Manual transmission:With your foot off
the accelerator pedal, crank the engine
by turning the engine switch to the
“START” position. Release it when the
engine starts.
Engine should be warmed up by driving,
not idling. For warming up drive with a
smoothly turning engine until the engine
coolant temperature is within the normal
range.
If the engine stalls...
Simply restart it, using the correct proce-
dure given in normal starting.
If the engine will not start...
See “If your vehicle will not start” on page
220 in Section 4.
NOTICE
zDo not crank for more than 30 se-
conds at a time. This may overheat
the starter and wiring systems.
zDo not race a cold engine.
zIf the engine becomes difficult to
start or stalls frequently, have the
engine checked immediately.
Pre−trip safety check
It is a good idea to do a safety check
before starting out on a trip. A few min-
utes of checking can help ensure safe and
pleasant driving. Just a basic familiarity
with your vehicle is required and a careful
eye! Or, if you would like, any authorized
Toyota dealer or repairer, or another duly
qualified and equipped professional, will
be pleased to make this check for you at
nominal cost.
CAUTION
If you make this check in an enclosed
garage, make sure there is adequate
ventilation. Engine exhaust is poison-
ous.
BEFORE STARTING THE ENGINE
Outside the vehicle
Tires.Check the pressure with a gauge
and look carefully for cuts, damage, or
excessive wear.
Wheel bolts.Make sure no bolts are mis-
sing or loose.
Fluid leaks.After the vehicle has been
parked for a while, check underneath for
leaking fuel, oil, water, or fluid. (Water
dripping from the air conditioning after use
is normal.)
Lights.Make sure the headlights, stop
lights, tail lights, turn signals and other
lights are all working. Check the headlight
aim.
Inside the vehicle
Spare tire, jack and wheel bolt wrench.
Check the spare tire pressure and make
sure you have your jack and wheel bolt
wrench.

in Section 7−1.)
Coolant level.Make sure the coolant lev-
el is correct. (See page 267 in Section
7−2 for instructions.)
Battery and cables.All the battery cells
should be filled to the proper level with
distilled water. Look for corroded or loose
terminals and a cracked case. Check the
cables for good condition and connections.
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.Listen for any leakage.
Have any leaks fixed immediately. (See
“Engine exhaust cautions” on page 198 in
Section 2.)
Engine oil level.Stop the engine and
check the dipstick with the vehicle parked
on a level spot. (See page 264 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!
