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.

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.

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.

2-9. Driving Tips
Winter Driving
Carry emergency gear, including tire chains, window scraper, flares, a
small shovel, jumper cables, and a small bag of sand or salt.
Ask your Toyota dealer to check the following:
• Have the proper ratio of ant ifreeze in the radiator.
Refer to Engine Coolant on P. 398.
• Inspect the battery and its cabl es. Cold reduces battery capacity.
• Use an engine oil appropriate for the lowest ambient temperatures that the vehicle w ill be driven in (P. 395).
• Inspect the ignition system for damage and loose connections.
• Use washer fluid made with antifreeze but do not use engine cool-
ant antifreeze for washer fluid ( P. 402).
●Do not use the parking brake in freezing weather as it may freeze. Instead,
shift to 1 or R with a manual transaxle and to P with an automa tic transaxle.
Block the rear wheels.
● Remove snow before driving. Snow left on the windshield is dang erous as it
could obstruct vision.
● Do not apply excessive force to a window scraper when removing ice or fro-
zen snow on the mirror glass and windshield.
● Never use warm or hot water for removing snow or ice from windo ws and
mirrors as it could result in the glass cracking.
● Drive slowly. Braking performance can be adversely affected if snow or ice
adheres to the brake components. If this situation occurs, drive the vehicle
slowly, releasing the accelerator pedal and lightly applying the brakes sev-
eral times until the brake performance returns to normal.

When Driving
If the selector lever will not move from P using the proper shift proce-
dure, continue to hold down the brake pedal.
Remove the shift-lock override
cover using a cloth-wrapped flat
head screwdriver.
Insert a screwdriver and push it
down.
Press and hold the lock-release
button.
Move the selector lever.
Take the vehicle to your Toyota dealer to have the system check ed.
The manual shift mode gives you the feel of driving a manual tran-
saxle vehicle by allowing you to operate the selector lever man ually.
This allows you to control engine rpm and torque to the drive w heels
much like a manual transaxle when more control is desired.
To change to manual shift mode,
shift the lever from D to M.
To return to automatic shift mo de, shift the lever from M to D.
