engine’s perf ormance and longevity.
Always use a premium-grade 0W-20
detergent oil displaying the API

Always use Honda Long-lif e Anti-
f reeze/Coolant Type 2. This coolant
is pre-mixed with 50 percent
antif reeze and 50 percent distilled
water. Never add straight antif reeze
or plain water.
If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX line.
Inspect the cooling system f or leaks. If Honda antif reeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporaryreplacement.Makesureit
is a high-quality coolant
recommended f or aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,
causing the cooling system to
malf unction or f ail. Have the cooling
system f lushed and ref illed with
Honda antif reeze/coolant as soon as
possible.

If you regularly drive your vehicle
under severe conditions in very low
temperature (under 31°F, 35°C), a
higher concentration of coolant should
be used. Consult your Honda dealer
f or more inf ormation on the proper
coolant.

The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Pourthecoolantslowlyand

Clean up any spill immediately; it
could damage components in the

Put the radiator cap back on, and
tighten it fully.Pour coolant into the reserve tank.
Fill it to half way between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your vehicle’s
cooling system. They may not be
compatible with the coolant or
engine components.
If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
Remove the radiator cap by
pushingitdownandturningit
counterclockwise. Relieve any pressure in the cooling
system by turning the radiator cap
counterclockwise, without
pressing down. Make sure the engine and radiator

Tires marked ‘‘M S’’ or ‘‘All
Season’’ on the sidewall have an all-
weather tread design suitable for
most winter driving conditions.
For the best perf ormance in snowy
or icy conditions, you should install
snow tires or tire chains. They may
be required by local laws under
certain conditions.
If you mount snow tires on your
vehicle, make sure they are radial
tires of the same size and load range
as the original tires. Mount snow
tires on all f our wheels. The traction
provided by snow tires on dry roads
maybelowerthanyouroriginaltires.
Check with the tire dealer f or
maximum speed recommendations. Mount tire chains on your tires when
required by driving conditions or
local laws. Install them only on the
f ront tires.
Because your vehicle has limited tire
clearance, Honda strongly
recommends using the chains listed
below, made by Security Chain
Company (SCC).

grading inf ormation, and page f or tire size inf ormation.

Check the condition of the battery

battery explains the test indicator’s
colors. Check the terminals f or corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it of f with plain
water. Dry off the battery with a
cloth or paper towel. Coat the
terminals with grease to help prevent
f uture corrosion. Battery posts,
terminals, and related accessories
contain lead and lead compounds.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle’s
electrical system. Always disconnect
the negative ( ) cable first, and
reconnect it last. If additional battery maintenance is
needed, see your dealer or a
qualif ied mechanic.
The location of the test indicator
window varies between
