uuIndicator, Coming On/Blinking uIf 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 Speed-Sensitive Electric Power Steering (EPS) System Indicator Comes On
■Reasons for the indicator to come on
• Comes on if there is a problem with the EPS system.
• 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
inspected by a dealer.
1 If 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.
u If 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.
u If 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
Confirm the specified amperage using the charts on
P. 474 to P. 478.
There is a fuse puller on the back of the engine
compartment fuse box cover.

Information
Emissions TestingTesting of Readiness CodesYour vehicle has “Readiness Codes,” as part of the onboard self diagnostic system.
Some States use these codes as a test to see if your vehicle’s emissions components
are working properly.
The codes may not be read properly if testing is performed 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
for 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 faci lity determines the readiness codes
are still not set, see a dealer.
