*1: If the message SERVICE DUE NOW does not appear more than 12 months after the display is
reset, change the engine oil every year.
# : See information on maintenance and emissions warranty.
*2: If you drive in dusty conditions, replace the air cleaner element every 15,000 miles (24,000 km).
*3: If you drive primarily in urban areas that have high concentrations of soot in the air from industry and
from diesel-powered vehicles, replace the dust and pollen filter every 15,000 miles (24,000 km).
CODEMaintenance Main Items
A●Replace engine oil*1
B●Replace engine oil*1 and oil filter●Inspect front and rear brakes●Check parking brake adjustment●Inspect tie rod ends, steering gearbox, and boots●Inspect suspension components●Inspect driveshaft boots●Inspect brake hoses and li nes (Including ABS/VSA)●Inspect all fluid levels and condition of fluids●Inspect exhaust system#
●Inspect fuel lines and connections#*4: If you drive regularly in very high temperatures (over 110 °F, 43 °C), in very low temperatures (under -
20 °F, -29 °C), or tow a trailer, replace every 60,000 miles/100,000 km.
*5: 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/12,000 km, then every 15,000 miles/24,000 km.

Maintenance
Engine Coolant
This coolant is premixed with 50% an tifreeze and 50% water. Do not add any
straight antifreeze or water.
We recommend you check the engine coolant level every time you refuel. Check the
reserve tank first. If it is completely empty, also check the coolant level in the
radiator. Add the engine coolant accordingly.
1.Check the amount of coolant in the reserve
tank.
2. If the coolant level is below the MIN mark,
add the specified coolant until it reaches
the MAX mark.
3. Inspect the cooling system for leaks.
Specified coolant: Honda Long Life Antifreeze/Coolant Type 2
■Reserve Tank
1Engine Coolant
If Honda antifreeze/coolant is not available, you may
use another major brand non-silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended for aluminum engines.
Continued use of any non-Honda coolant can result
in corrosion, causing the cooling system to
malfunction or fail. Have the cooling system flushed
and refilled with Honda antifreeze/coolant as soon as
possible.
Do not add rust inhibitors or other additives to your
vehicle’s cooling system. They may not be compatible
with the coolant or with the engine components.

Maintenance
1. Make sure the engine and radiator are
cool.
2. Turn the radiator cap counterclockwise and
relieve any pressure in the coolant system.
Do not push the cap down when turning.
3. Push down and turn the radiator cap
counterclockwise to remove it.
4. The coolant level should be up to the base
of the filler neck. Add coolant if it is low.
5. Put the radiator cap back on, and tighten it
fully.
6. Pour coolant into the reserve tank until it
reaches the MAX mark. Put the cap back
on the reserve tank.
■Radiator1 Radiator
NOTICEPour the fluid slowly and carefully so you do not spill
any. Clean up any spills immediately; they can
damage components in the engine compartment.
3WARNING
Removing the radiator cap while the
engine is hot can cause the coolant to spray
out, seriously scalding you.
Always let the engine and radiator cool
down before removing the radiator cap.Radiator Cap

Maintenance
A good coat of automotive body wax helps protect your vehicle’s paint from the
elements. Wax will wear off over time and expose your vehicle’s paint to the
elements, so reapply as necessary.
If you get gasoline, oil, engine coolant, or battery fluid on resin coated parts, they
may be stained or the coating may peel. Promptly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.
Aluminum is susceptible to deterioration caused by salt and other road
contaminants. Use a sponge and mild detergent to wipe away promptly.
Be careful not to use harsh chemicals (inc luding some commercial wheel cleaners) or
a stiff brush. They can damage the clear coat of the aluminum alloy wheels that
helps keep the aluminum fro m corroding and tarnishing.

1Applying Wax
NOTICEChemical solvents and stro ng cleaners can damage
the paint, metal, and plasti c on your vehicle. Wipe up
spills immediately.
1 Maintaining the Bumpers and Other Resin Coated Parts
Ask a dealer about the correct coating material when
you want to repair the pa inted surface of the parts
made of resin.
1 Cleaning the Window
Wires are mounted to the inside of the rear window.
Wipe along the same direction as the wires with a
soft cloth so as not to damage them.

uuOverheating uHow to Handle Overheating
Handling the Unexpected
■Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the temperature
gauge needle comes down.
u If the cooling fan is not operating,
immediately stop the engine.
2. Once the engine has cooled down, inspect
the coolant level and check the cooling
system components for leaks.
u If the coolant level in the reserve tank is
low, add coolant until it reaches the
MAX mark.
u If there is no coolant in the reserve tank,
check that the radiator is cool. Cover the
radiator cap with a heavy cloth and open
the cap. If necessary, add coolant up to
the base of the filler neck, and put the
cap back on.
■Last thing to do
Once the engine has cooled sufficiently, restart it and check the temperature gauge.
If the temperature gauge needle has gone down, resume driving. If it has not gone
down, contact a dealer for repairs.
1 How to Handle Overheating
If the coolant is leaking, contact a dealer for repairs.
Use water as an emergency/temporary measure only.
Have a dealer flush the syst em with proper antifreeze
as soon as possible.
3WARNING
Removing the radiator cap while the
engine is hot can cause the coolant to spray
out, seriously scalding you.
Always let the engine and radiator cool
down before removing the radiator cap.
