*1: If a Maintenance Minder message 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.
CODEMaintenance Main Items
A
●Replace engine oil*1
B●Replace engine oil*1 and oil filter●Inspect front and rear brakes●Inspect these items: • Tie rod ends, steering gearbox, and boots
• Suspension components
• Driveshaft boots
• Brake hoses and lines (including ABS/VSA®)
• All fluid levels and condition of fluids
• Exhaust system
#
•Fuel lines and connections#
*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).
*4: If you drive regularly in very high temperatures (over 110°F, 43°C), in very low temperatures (under -20°F, -29°C), or towing 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).
*6: If a Maintenance Minder message does not appear more than 36 months after the display for item 7 is reset, change the brake fluid every 3 years.

Maintenance
Engine Coolant
This coolant is premixed with 50% antifreeze 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. Make sure the engine and radiator are cool.
2. Check the amount of coolant in the reserve
tank.
u 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
NOTICE
Genuine Honda engine coolant is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as about -31°F (-35°C). If your
vehicle is consistently subjected to temperatures below
this, the concentration of antifreeze in the coolant
should be increased. Consult a dealer for details.
If Honda antifreeze/coolant is not available, you may use
another major brand of 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. Th ey may not be compatible
with the coolant or with the engine components.
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.

1. Make sure the engine and radiator are
cool.
2. Remove the engine compartment cover.

3.Turn the radiator cap 1/8th turn counter-
clockwise and relieve any pressure in the
cooling system. Do not push the cap down
when turning.
4. Push down and turn the radiator cap
counter-clockwise to remove it.
5. The coolant level should be up to the base
of the filler neck. Add coolant if it is low.
6. Put the radiator cap back on, and tighten it
fully.

uuCleaning uExterior Care
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 resi n-coated parts, they
may stain or the coating may peel. Prompt ly 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. When necessary, as early as possible use a sponge and mild detergent
to wipe away these contaminants. Do no t use a stiff brush or harsh chemicals
(including some commercial wheel cleaners). These can damage the protective finish
on aluminum alloy wheels, resulting in corrosion. Depending on the type of finish,
the wheels also may lo se their luster or appear burn ished. To avoid water stains,
wipe the wheels dry with a cloth while they are still wet.

NOTICE
Chemical solvents and st rong cleaners can damage

Ask a dealer about the corr ect coating material when
you want to repair the painted surface of the parts
made of resin.

1.Check that the cooling fan is operating and
stop the engine once Engine temperature
too hot. Do not drive. Allow engine to
cool. on the driver information interface

u If the cooling fan is not operating,
immediately stop the engine.
2. Once the engine has cooled down, inspect
the coolant level an d 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 coolan t in the reserve tank,
check that the radiator is cool. Remove
the engine compartment cover. 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 driver information
interface.
If Engine temperature too hot. Do not drive. Allow engine to cool. does not
appear, resume driving. If it appear s again, contact a dealer for repairs.
1How 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 system with proper antifreeze
as soon as possible.
