Immobilizer System
If someone attempts to start the engine with an unrecognized key, the
engine will not start, thereby helping to prevent vehicle theft.
If you have a problem with the immobilizer system or the key, consult
your Toyota dealer.
● The keys carry a unique electronic code. For this reason, and to 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 States.
Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
● 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 dashboard
or hood, under direct sunlight.
● If the engine does not start with the correct key, and the security indicator
light keeps illuminating or flashing, the system may have a malfunction.
Consult your Toyota dealer.

2-7. Security System
■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 of f. If the engine does not start with
the correct key, and th e security indicator light remains illuminated
or flashing, try the following:
Make sure the key is within the operational range for signal trans-
mission. Switch the ignition off, 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 illuminate 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. Move 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 mobile 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 will not be able to
restart it.
● Because the electronic codes are reset when the immobilizer system is
repaired, the keys are needed. Make sure to bring all the keys to your Toy-
ota dealer so that they can be programmed.

Before Driving
Saving Fuel and Protection of the Environment
How you operate your Toyota determines how far it will travel on a
tank of fuel. Use these suggestions to help save fuel and reduce CO2.
• Avoid long warm-ups. Once the en gine runs smoothly, begin driv-
ing.
• Avoid fast starts.
• Drive at lower speeds.
• Anticipate when to apply the brakes (avoid sudden braking).
• Follow the maintenance schedule and have your Toyota dealer per- form inspections and servicing.
• Use the air conditioner only when necessary.
• Slow down on rough roads.
• Keep the tires properly inflated.
• Do not carry unnecessary weight.
• Do not rest your foot on the brake pedal while driving.
• Keep the wheels in correct alignment.
• Keep windows closed at high speeds.
• Slow down when driving in crosswinds and headwinds.
WARNING
■ Never stop the engine when going down a hill
Stopping the engine when going down a hill is dangerous. This causes the
loss of power steering and power brake control, and may cause damage to
the drivetrain. Any loss of steering or braking control could cause an acci-
dent.

2-8. Driving Tips
Hazardous Driving
When driving on ice or in water, snow, mud, sand, or similar hazards:• Be cautious and allow ex tra distance for braking.
• Avoid sudden braking and sudden maneuvering.
• Do not pump the brakes. Continue to press down on the brake pedal. Refer to Antilock Brake System (ABS) on P. 193.
• If you get stuck, select a lower g ear and accelerate slowly. Do not
spin the front wheels.
• For more traction in starting on slippery surfaces such as ice or packed snow, use sand, rock salt, chains, carpeting, or other non-
slip material under the front wheels.
Use snow chains only on the front wheels.
WARNING
■ Be extremely careful if it is n ecessary to downshift on slippery sur-
faces
Downshifting into lower gear while driving on slippery surfaces is danger-
ous. The sudden change in tire speed could cause the tires to skid. This
could lead to loss of vehicle control and an accident.
