4. Turn off the engine.
Always set the parking brake firmly, in part icular if you are parked on an incline.
1Parking Your Vehicle
Do not park your vehicle near flammable objects,
such as dry grass, oil, or timber.
Heat from the exhaust can cause a fire.
1 When Stopped
NOTICE
The following can dama ge the transmission:
•Depressing the accelerator and brake pedals
simultaneously.
•Holding the vehicle in place when facing uphill by
depressing the accelerator pedal.
•Moving the shift lever into ( P before the vehicle
stops completely.
In extremely cold temperatures, the parking brake
may freeze up if applied. If such temperatures are
expected, do not apply the parking brake but, if
parking on a slope, either turn the front wheels so
they will contact the curb if the vehicle rolls down the
slope or block the wheels to keep the vehicle from
moving. If you do not take either precaution, the
vehicle may roll unexpect edly, leading to a crash.

Before Performing Maintenance
Inspection and Maintenance
For 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 maintena nce 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 automatic transmission fluid level monthly.
2 Automatic Transmission Fluid P. 362
•Check the brake fluid level monthly.
2 Checking the Brake Fluid P. 363
•Check the tire pressure monthly. Examin e the tread for wear and foreign objects.
2Checking and Maintaining Tires P. 376
•Check the operation of the exterior lights monthly.
2Replacing Light Bulbs P. 365
•Check the condition of the wiper bl ades at least every six months.

■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 fede ral regulations, failure to

Safety When Performing Maintenance
Some of the most important safe ty precautions are given here.
However, we cannot warn you of every conceivable hazard that can arise in
performing maintenance. Only you can decide whether or not you should perform
a given task.
• To reduce the possibility of fire or explos ion, keep cigarettes, sparks, and flames
away from the battery and all fuel related parts.
• Never leave rags, towels, or other flammable objects under the hood.
u Heat from the engine and exhaust can ignite them causing a fire.
• To clean parts, use a co mmercially available degreas er or parts cleaner, not
gasoline.
• Wear eye protection and protective clothi ng when working with the battery or
compressed air.
• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
u Only operate the engine if th ere is sufficient ventilation.
• The vehicle must be in a stationary condition.
u Make sure your vehicle is parked on le vel ground, the parking brake is set, and
the engine is off.
• Be aware that hot parts can burn you.
u Make sure to let the engine and exhaust system cool thoroughly before
touching vehicle parts.
• Be aware that moving parts can injure you.
u Do not start the engine unless instruct ed, and keep your hands and limbs away
from moving parts.

from diesel-powered vehicles, replace the dust and pollen filter every 15,000 miles (24,000 km).
*4: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher transmission and transfer temperatures. This requires transmission and transfer fluid changes more frequently than
recommended by the Maintenance Minder. If you regularly drive your vehicle under these conditions, have
the transmission fluid changed at 60,000 miles (100,000 km), then every 30,000 miles (48,000 km).
*5: If you drive regularly in very high temperatures (over 110 °F, 43 °C), in very low temperatures (under -
20 °F, -29 °C), replace every 60,000 miles/100,000 km.

■Checking the Brake Fluid
1Brake Fluid
NOTICE
Brake fluid marked DOT 5 is not compatible with your
vehicle’s braking system and can cause extensive
damage.
If the specified brake fluid is not available, you should
use only DOT 3 or DOT 4 fluid from a sealed
container as a temporary replacement.
Using any non-Acura brake fl uid can cause corrosion
and decrease the longevity of the system. Have the
brake system flushed and re filled with Acura Heavy
