Types of Inspection and Maintenance
1Inspection and Maintenance
Maintenance, replacement, or repair of
emissions control devices and systems may be
done by any automotive repair establishment or
individuals using parts that are “certified” to
EPA standards.
According to state and federal regulations, failure to
perform maintenance on the maintenance main
items marked with # will not void your emissions
warranties. However, all maintenance services should
be performed in accordance with the intervals
indicated by the multi-information display.

uuChecking and Maintaining Tires uTire and Wheel Replacement
Maintenance
Tire and Wheel ReplacementReplace your tires with radials of the same size, load range, speed rating, and
maximum cold tire pressure rating (as shown on the tire’s sidewall). Using tires of \
a
different size or construction can cause the ABS, VSA ® (vehicle stability assist), hill
start assist, and the AWD (All-Wheel Drive) with intelligent control system
* to work
incorrectly.
It is best to replace all four tires at the same time. If that isn’t possible, replace the
front or rear tires in pairs.
If you replace a wheel, only use TPMS specified wheels approved for your vehicle.
Make sure that the wheel’s specifications match those of the original wheels.

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 EPS System Indicator Comes On
■
Reasons for the indicator to come on
• Comes on when there is a problem with 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.

1 If the EPS System Indicator Comes On
NOTICEIf 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 system is restored. Repeated
operation under these conditions can eventually
damage the system.

Information
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
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 facility determines the readiness codes
are still not set, see a dealer.
