Before Performing MaintenanceInspection and MaintenanceFor your safety, perform all listed inspections and maintenance to keep your vehicle
in good condition. If you become aware of any abnormality (noise, smell, insufficient
brake fluid, oil residue on the ground, etc.), have your vehicle inspected by a dealer.
(Note, however, that service at a dealer is not mandatory to keep your \
warranties in
effect.) Refer to the separate maintenance booklet for detailed maintenance and
inspection information.■Daily inspections
Perform inspections before long distance trips, when washing the vehicle, or when
refueling.■Periodic inspections
• Check the brake fluid level monthly.2 Checking the Brake Fluid P. 410
•Check the tire pressure monthly. Examine the tread for wear and foreign objects.
2 Checking and Maintaining Tires P. 421
•Check the operation of the exterior lights monthly.

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 (MID).

information, replace the brake fluid every 3 years.•Inspect idle speed every 160,000 miles (256,000
km).•Adjust the valves during services A, B, 1, 2, or 3 if
they are noisy.
Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher level of
mechanical (Shear) stress to fluid. This requires
differential fluid changes more frequently than
recommended by the Maintenance Minder. If you
regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles
(12,000km), then every 15,000 miles (24,000 km).

following operations:
• Press and hold the ENGINE START/STOP button for about two seconds.
• Firmly press the ENGINE START/STOP button two times.
The steering wheel will not lock. However, because turning off the engine disables
the power assist the engine provides to the steering and braking systems, it will
require significantly more physical effort and time to steer and slow the vehicle. Use
both feet on the brake pedal to slow down the vehicle and stop immediately in a
safe place.
The power mode is in ACCESSORY when the engine is stopped.
To change the mode to VEHICLE OFF, change the gear position to
(P
after the
vehicle comes to a complete stop. Then press the ENGINE START/STOP button
twice without depressing the brake pedal.

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.
