291
Handling the Unexpected
If the Malfunction Indicator Lamp Comes On or
Blinks
If the Malfunction Indicator Lamp Comes On or Blinks NOTICE If you drive with the malfunction indicator lamp on,
the emissions control system and the engine could
be damaged.
If the malfunction indicator lamp blinks again when
restarting the engine, drive to the nearest dealer
at 31 mph (50 km/h) or less. Have your vehicle
inspected.
Reasons for indicator lamp to come on or blink
Comes on when there is a problem with the engine emissions control t
system, or the fuel fill cap is missing, or loose.
Blinks when engine misfiring is detected. t What to do when the indicator lamp comes on
Avoid high speeds and immediately get your vehicle inspected at your
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.
Tighten Fuel Fill Cap Message The message appears on when:
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.

If not, loosen the cap, and then retighten it until it clicks at least once.
3. Drive for several days of normal driving.
The 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.

Indicator, Coming On/Blinking
If the Brake System Indicator Comes On
292Handling the Unexpected
If the Brake System Indicator Comes On
Reasons for the indicator to come on
The brake fluid is low. t
There is a malfunction in the brake system. t 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. t
If abnormal, take immediate action. If necessary, downshift the t
transmission to slow the vehicle using engine braking.
If the Brake System Indicator 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 brake distribution
system is not working. This can result in vehicle
instability under sudden braking.
Have your vehicle inspected by a dealer immediately.
U.S.
CanadaIf the EPS Indicator Comes On
Reasons for the indicator to come on
Comes on when there is a problem with EPS. t
If you depress the accelerator pedal repeatedly to increase the t
engine speed while the engine is idling, the indicator comes on, and
sometimes the steering wheel becomes harder to operate. What to do when the indicator comes on
Stop the vehicle in a safe place and restart the engine.
If the indicator comes on and stays on, immediately have your vehicle
inspected by a dealer.
If the EPS Indicator Comes On NOTICE If you repeatedly turn the steering wheel at an
extremely low speed, or hold the steering wheel
on the full left or right position for a while, the
system heats up. The system goes into a protective
mode, and limits its performance. The steering
wheel becomes harder and harder to operate. Once
the system cools down, EPS is restored. Repeated
operation under these conditions can eventually
damage the system.

Fuses
294Handling the Unexpected
If any electrical devices are not working, turn the ignition switch to LOCK 0
and
check to see if any applicable fuse is blown.
Engine Compartment Fuse Box

Inspecting and Changing Fuses
297
Handling the Unexpected
Inspecting and Changing Fuses
1. Turn the ignition switch to LOCK 0
. Turn
headlights and all accessories off.
2. Remove the fuse box cover.
3. Check the large fuse in the engine
compartment.
If the fuse is blown, use a Phillips-head
screwdriver to remove the screw and
replace it with a new one.

Combined Fuse
Inspecting and Changing Fuses NOTICE Replacing a fuse with one that has a higher rating
greatly increases the chances of damaging the
electrical system. If you do not have a replacement
fuse with the proper rating for the circuit, install
one with a lower rating.
Replace fuse with a spare fuse of the same specified
amperage.
Confirm the specified amperage using the charts on
P. 2 9 4 t o P. 2 9 6 .
There is a fuse puller on the back of the engine
compartment fuse box.
4. Inspect the small fuses in the engine
compartment and the vehicle interior.
If there is a burned out fuse, remove it
with the fuse puller and replace it with a
new one.

Emissions Testing
Continued
Information
Your vehicle uses "readiness codes," as part of it's 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, turn the ignition switch to ON
II
, 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
(automatic transmission) or
N
(manual transmission).
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.
Testing 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.
