2-4. Fuel and Emission
This vehicle is equipped with an emission control system (the catalytic
converter is part of this system) that enables the vehicle to c omply
with existing exhaust emissions requirements.
●Under U.S. federal law, any modification to the original-equipm ent emission
control system before the first sale and registration of a vehi cle is subject to
penalties. In some states, such modification made on a used veh icle is also
subject to penalties.
● While the engine is off, the sound of a valve opening and closi ng can be
heard at the rear of the vehicle, however this does not indicat e an abnormal-
ity. The vehicle has a selfchecking device and it operates whil e the engine is
off.
Emission Control System
WARNING
■ Never park over or near anything flammable
Parking over or near anything flammable, such as dry grass, is dangerous.
Even with the engine turned off, the exhaust system remains very hot after
normal use and could ignite anything flammable. A resulting fir e could
cause serious injury or death.
NOTICE
Ignoring the following precautions could cause lead to accumula te on the
catalyst inside the converter or cause the converter to get ver y hot. Either
condition will damage the converter and cause poor performance.
● USE ONLY UNLEADED FUEL.
● Do not drive your Toyota with any sign of engine malfunction.
● Do not coast with the ignition switched off.
● Do not descend steep grades in gear with the ignition switched off.
● Do not operate the engine at high idle for more than 2 minutes.
● Do not tamper with the emission control system. All inspections and
adjustments must be made by a qualified technician.
● Do not push-start or pull-start your vehicle.

Before Driving
Engine Exhaust (Carbon monoxide)
WARNING
■Do not drive your vehicle if you smell exhaust gas inside the v ehicle
Engine exhaust gas is dangerous. This gas contains carbon monox ide
(CO), which is colorless, odorless, and poisonous. When inhaled , it can
cause loss of consciousness and death. If you smell exhaust gas inside the
vehicle, keep all windows fully open and contact your Toyota de aler immedi-
ately.
■ Do not run the engine when inside an enclosed area
Running the engine inside an enclosed area, such as a garage, i s danger-
ous. Exhaust gas, which contains poisonous carbon monoxide, cou ld easily
enter the cabin. Loss of consciousness or even death could occu r.
■ Open the windows or adjust the heating or cooling system to draw
fresh air when idling the engine:
Exhaust gas is dangerous. When the vehicle is stopped with the windows
closed and the engine running for a long time even in an open a rea,
exhaust gas, which contains poisonous carbon monoxide, could en ter the
cabin. Loss of consciousness or even death could occur.
■ Clear snow from underneath and around your vehicle, particularl y the
tail pipe, before starting the engine:
Running the engine when a vehicle is stopped in deep snow is da ngerous.
The exhaust pipe could be blocked by the snow, allowing exhaust gas to
enter the cabin. Because exhaust gas contains poisonous carbon monox-
ide, it could cause loss of consciousness or even death to occu pants in the
cabin.

2-4. Fuel and Emission
Fuel-Filler Lid and Cap
WARNING
■When removing the fuel-filler cap, loosen the cap slightly and wait for
any hissing to stop, then remove it
Fuel spray is dangerous. Fuel can burn skin and eyes and cause illness if
ingested. Fuel spray is released when there is pressure in the fuel tank and
the fuel-filler cap is removed too quickly.
■ Before refueling, stop the engine, and always keep sparks and f lames
away from the filler neck
Fuel vapor is dangerous. It could be ignited by sparks or flame s causing
serious burns and injuries.
Additionally, use of the incorrect fuel-filler cap or not using a fuel-filler cap
may result in a fuel leak, which could result in serious burns or death in an
accident.
■ Do not continue refueling after the fuel pump nozzle shuts off automat-
ically
Continuing to add fuel after the fuel pump nozzle has shut off automatically
is dangerous because overfilling the fuel tank may cause fuel o verflow or
leakage. Fuel overflow and leakage could damage the vehicle and if the fuel
ignites it could cause a fire and explosion resulting in serious injury or
death.
NOTICE
Always use only a genuine Toyota fuel-filler cap or an approved equivalent,
available at your Toyota dealer. The wrong cap can result in a serious mal-
function of the fuel and emission control systems.
It may also cause the check engine light in the combination met er to illumi-
nate.

NOTICE
If the check fuel cap warning light illuminates, the fuel-filler cap may not be
properly installed. If the warning light illuminates, park your vehicle safely off
the right-of-way, remove the fuel-filler cap and reinstall it c orrectly. After the
cap has been correctly installed, the fuel cap warning light ma y continue to
illuminate until a number of driving cycles have been completed. A drive
cycle consists of starting the engine (after four or more hours with the
engine off) and driving the vehicle on city and highway roads.
Continuing to drive with the check fuel cap warning light illum inated could
cause the check engine light to illuminate as well.

2-8. Security System
Immobilizer System
If someone attempts to start the engine with an unrecognized ke y, the
engine will not start, thereby helping to pre vent vehicle theft.
If you have a problem with the i mmobilizer system or the key, consult
your Toyota dealer.
● The keys carry a unique electronic code. For this reason, and t o assure your
safety, obtaining a replacement key requires some waiting time. They are
only available through your Toyota dealer.
● Always keep a spare key in case one is lost. If a key is lost, consult your
Toyota dealer as soon as possible.
● If you lose a key, your Toyota dealer will reset the electronic codes of your
remaining keys and immobilizer system. Bring all the remaining keys to your
Toyota dealer to reset.
Starting the vehicle with a key that has not been reset is not possible.
The immobilizer system allows the engine to start only with a
key the system recognizes.
NOTICE
● Radio equipment like this is governed by laws in the United Sta tes.
Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the e quipment.
● To avoid damage to the key, do not:
• Drop the key.
• Get the key wet.
• Expose the key to any kind of magnetic field.
• Expose the key to high temperatures on places such as the dash board
or hood, under direct sunlight.
● If the engine does not start with the correct key, and the secu rity indicator
light keeps illuminating or flashing, the system may have a mal function.
Consult your Toyota dealer.

1372-8. Security System
2
Before Driving
■Arming
The system is armed when the
ignition is switched from ON to
off.
The security indicator light in
the combination meter flashes
every 2 seconds until the sys-
tem is disarmed.
■Disarming
The system is disarmed when the ignition is switched ON with the
correct programmed key. The security indicator light illuminates for
about 3 seconds and then turns off. If the engine does not star t with
the correct key, and the security indicator light remains illuminated
or flashing, try the following:
Make sure the key is within the operational range for signal tr ans-
mission. Switch the ignition of f, and then restart the engine. If the
engine does not start after 3 or more tries, contact your Toyota
dealer.
● The engine may not start and security indicator light may illum inate or flash
if the key is placed in an area where it is difficult for the system to detect the
signal, such as on the dashboard or in the glove compartment. M ove the
key to a location within the signal range, switch the ignition off, and then
restart the engine.
● Signals from a TV or radio station, or from a transceiver or mo bile telephone
could interfere with your immobilizer system. If you are using the proper key
and the engine fails to start, check the security indicator light.
● If the security indicator light flashes continuously while you are driving, do
not shut off the engine. Go to your Toyota dealer and have it checked. If the
engine is shut off while the indicator light is flashing, you w ill not be able to
restart it.
● Because the electronic codes are reset when the immobilizer sys tem is
repaired, the keys are needed. Make sure to bring all the keys to your Toy-
ota dealer so that they can be programmed.
