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 ECPS Indicator* Comes On
■Reasons for the indicator to come on
• Comes on when there is a problem with ECPS.
• If you depress the accelerator pedal repeatedly to increase the 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

1 If the Brake System In dicator (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 plac e. If necessary downshift
the gears.
If the brake system indica tor 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.U.S.
Canada
1 If the ECPS Indicator* Comes On
NOTICEIf you repeatedly turn the steering wheel at an
extremely low speed, or ho ld 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, ECPS is restored. Repeated
operation under these conditions can eventually
damage the system.

instead of an ig nition switch.1Inspecting and Changing Fuses
NOTICEReplacing 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.
Use the charts to locate the fuse in question and
confirm the specified ampe rage on the fuse label.

Information
Emissions Testing
Testing of Readiness Codes
Your vehicle uses “readiness codes,” as part of its onboard self diagnostic system.
Some states refer to these codes during te sting to see if your vehicle’s emissions
components are working properly.
The codes may not be read if you go thro ugh the testing just after the battery has
gone dead or been disconnected.
To check if they are set, tu rn the ignition switch to ON
w*1, 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 te sted 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 en gine 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 touc hing 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 l east 1/4 of the scale (about 3 minutes).
6. Let the engine idle with your foot off the accelerator for 20 seconds.
*1: Models with the keyless access system have an ENGINE START/STOP button
instead of an ignition switch.
1 Testing of Readiness Codes
The readiness codes are eras ed when the battery is
disconnected, and set again on ly after several days of
driving under a variety of conditions.
If a testing facility determ ines 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 dete rmines the readiness codes
are still not set, see a dealer.
