Handling the Unexpected
■Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the temperature
gauge needle comes down.
uIf the cooling fan is not operating,
immediately stop the engine.
2.Once the engine has cooled down, inspect
the coolant level and check the cooling
system components for leaks.
uIf the coolant level in the reserve tank is
low, add coolant until it reaches the
MAX mark.
uIf there is no coolant in the reserve tank,
check that the radiator is cool. Cover the
radiator cap with a heavy cloth and open
the cap. If necessary, add coolant up to
the base of the filler neck, and put the
cap back on.■Last thing to do
Once the engine has cooled sufficiently, restart it and check the temperature gauge.
If the temperature gauge needle has gone down, resume driving. If it has not gone
down, contact a dealer for repairs.
1How to Handle Overheating
If the coolant is leaking, contact a dealer for repairs.
Use water as an emergency/temporary measure only.
Have a dealer flush the system with proper antifreeze
as soon as possible.

WARNING
Removing the radiator cap while the
engine is hot can cause the coolant to spray
out, seriously scalding you.
Always let the engine and radiator cool
down before removing the radiator cap.

Handling the Unexpected
If the Malfunction Indicator Lamp Comes On or Blinks
■Reasons for indicator lamp to come on or blink
•Comes on when there is a problem with the engine emissions control
system, or the fuel fill cap is missing, or loose.
•Blinks when engine misfiring is detected.■What to do when the indicator lamp comes on
Avoid high speeds and immediately get your vehicle inspected at a
dealer.■What to do when the indicator lamp blinks
Park the vehicle in a safe place with no flammable items and wait at least
ten minutes or more with the engine stopped until it cools.

An evaporative system leak is detected. This may be caused by the fuel fill cap being
loose or not being installed.■What to do when the message appears:
1.Stop the engine.
2.Check that the fuel fill cap is fully installed.
uIf not, loosen the cap, and then retighten it until it clicks at least once.
3.Drive for several days of normal driving.
uThe message should go off.■When the malfunction indicator lamp comes on
Malfunction indicator lamp comes on if the system continues to detect a leak of
gasoline vapor. If this happens, check the fuel fill cap using the procedures described
above.■Tighten Fuel Cap Message
1If the Malfunction Indicator Lamp Comes On or BlinksNOTICEIf you drive with the malfunction indicator lamp on,
the emissions control system and the engine could be
damaged.

uuIndicator, Coming On/BlinkinguIf the Brake System Indicator (Red) Comes On
Handling the Unexpected
If the Brake System Indicator (Red) Comes On
■Reasons for the indicator to come on
•The brake fluid is low.
•There is a malfunction in the brake system.■What to do when the indicator comes on while driving
Press the brake pedal lightly to check pedal pressure.
•If normal, check the brake fluid level the next time you stop.
•If abnormal, take immediate action. If necessary, downshift the
transmission to slow the vehicle using engine braking.
If the Low Tire Pressure/TPMS Indicator Comes On or Blinks
■Reasons for the indicator to come on or blink
A tire pressure is significantly low. If there is a problem with the TPMS or
the compact spare tire is installed, the indicator blinks for about one
minute, and then stays on.■What to do when the indicator comes on
Stop your vehicle in a safe place. Check the tire pressure and adjust the
pressure to the specified level. The specified tire pressure is on a label on
the driver side doorjamb.■What to do when the indicator blinks
Have the tire inspected by a dealer as soon as possible. If the compact
spare tire causes the indicator to blink, change the tire to a full-size tire.
The indicator goes off after driving for a few miles (kilometers).
1If the Brake System Indicator (Red) Comes On
Have your vehicle repaired immediately.
It is dangerous to drive with low brake fluid. If there
is no resistance from the brake pedal, stop
immediately in a safe place. If necessary downshift
the gears.
If the brake system indicator and ABS indicator come
on simultaneously, the electronic brake distribution
system is not working. This can result in vehicle
instability under sudden braking.
Have your vehicle inspected by a dealer immediately.

Handling the Unexpected
Inspecting and Changing Fuses
1.Set the power mode to VEHICLE OFF
(LOCK).
Turn headlights and all accessories off.
2.Remove the fuse box cover.
3.Check the large fuse in the engine
compartment.
uIf the fuse is blown, use a Phillips-head
screwdriver to remove the screw and
replace it with a new one.
4.Inspect the small fuses in the engine
compartment and the vehicle interior.
uIf there is a burned out fuse, remove it
with the fuse puller and replace it with a
new one.
1Inspecting and Changing FusesNOTICEReplacing a fuse with one that has a higher rating
greatly increases the chances of damaging the
electrical system.
Replace fuse with a spare fuse of the same specified
amperage.

310Information
Emissions TestingTesting of Readiness CodesYour vehicle uses “readiness codes,” as part of its onboard self diagnostic system.
Some states refer to these codes during testing to see if your vehicle’s emissions
components are working properly.
The codes may not be read if you go through the testing just after the battery has
gone dead or been disconnected.
To check if they are set, set the power mode to ON, without starting the engine. The
malfunction indicator lamp will come on for several seconds. If it then goes off, the
readiness codes are set. If it blinks five times, the readiness codes are not set.
If you are required to have your vehicle tested before the readiness codes are ready,
prepare the vehicle for retesting by doing the following:
1.Fill the gas tank to approximately 3/4 full.
2.Park the vehicle and leave the engine off for 6 hours or more.
3.Make sure the ambient temperature is between 40°F and 95°F (4°C and 35°C).
4.Start the engine without touching the accelerator pedal, and let it idle for 20
seconds.
5.Keep the vehicle in
(P. Increase the engine speed to 2,000 rpm, and hold it there
until the temperature gauge rises to at least 1/4 of the scale (about 3 minutes).
6.Let the engine idle with your foot off the accelerator for 20 seconds.
1Testing of Readiness Codes
The readiness codes are erased when the battery is
disconnected, and set again only after several days of
driving under a variety of conditions.
If a testing facility determines that the readiness
codes are not set, you may be requested to return at
a later date to complete the test.
If the testing facility determines the readiness codes
are still not set, see a dealer.
