Proper
use of the climate control
system can make the interior dry
and comfortable, and keep the
windows clear for best visibility.
For the climate control system to
provide heating and cooling, the
engine must be running.
You can adjust the temperatures of
thedriver’ssideandthepassenger’s
side independently (see page ).The
automatic climate control
system adjusts the fan speed and
airflow levels to maintain the interior
temperature you select. Set
the desired temperature by
pushing or of the driver’s
side temperature control buttons.
The selected temperature will
show in the display.
The system automatically selects the
proper mix of conditioned and/or
heated air that will, as quickly as
possible, raise or lower the interior
temperature to your preference.
Press
the AUTO button. You will
see AUTO in the display. The
indicator in the button also comes
on as a reminder.
In
the AUTO mode, the vehicle’s
interior temperature is
independently regulated for the
driver and passenger. If the driver’s
side of the vehicle is getting too
much sun, the system will adjust to a
lower temperature. When
you push the passenger’s side
temperature control buttons, the
indicator in the DUAL button comes
on and the driver’s side and
passenger’s side temperature can be
controlled independently (see page ).
The climate control system f or your
vehicle can also be operated by voice
control. See the navigation section in
your quick start guide f or an
overview of this system, and the
navigation system manual f or
complete details. 1.2.

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 the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
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. 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 water.
Never add straight antifreeze or
plain water.

The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Pourthecoolantslowlyand
caref ully so you do not spill any.
Clean up any spill immediately; it
could damage components in the
engine compartment.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.
Pour coolant into the reserve tank.
Fill it half way between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Make sure the engine and radiator
are cool.
Relieve any pressure in the cooling
system by turning the radiator cap
counterclockwise, without
pressing down.
Remove the radiator cap by
pushing down and turning
counterclockwise. Put the radiator cap back on, and
tighten it fully.

Your vehicle is equipped with a
intercooler on the engine to cool the
air f low f rom a turbo charger into
the engine. The intercooler f ins bend
easily. Do not push them with your
f inger.Have your dealer replace the filter
when this service is indicated by a
maintenance message on the
inf ormation display or multi-
inf ormation display (depending on
the models). It should be replaced
every 15,000 miles (24,000 km) if you
drive primarily in urban areas that
have high concentrations of soot in
the air, or if the flow from the
heating and cooling system becomes
less than usual. This f ilter removes the dust and
pollenthatisbroughtinfromthe
outside through the heating and
cooling system.

Your vehicle is equipped with an
antenna at the rear of the roof . Bef ore
using a ‘‘drive-through’’ car wash,
remove the antenna by unscrewing it by
hand. This prevents the antenna f rom
being damaged by the car wash brushes. Do not spray water (f rom such sources
as garden hoses, high pressure
sprayers) into the engine compartment.
It may cause serious damage to your
vehicle, and could also damage the
intercooler f ins.

Fill the f uel tank.
Change the engine oil and f ilter.
Wash and dry the exterior
completely.
Cleantheinterior.Makesurethe
carpeting, floor mats, etc., are
completely dry.Block the rear wheels.
If the vehicle is to be stored f or a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom a porous material such as
cotton. Non-porous materials, such
as plastic sheeting, trap moisture,
which can damage the paint.
If you need to park your vehicle f or
an extended period (more than 1
month), there are several things you
should do to prepare it f or storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your vehicle back on the road. If
possible, store your vehicle indoors. Leave one window open slightly (if
the vehicle is being stored
indoors).
Disconnect the battery.
Support the f ront and rear wiper
blade arms with a f olded towel or
ragsotheydonottouchthe

To minimize sticking, apply a
silicone spray lubricant to all door
and tailgate seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and tailgate seals.If possible, periodically run the
engine until it reaches f ull
operating temperature (the
cooling f ans cycle on and of f
twice). Pref erably, do this once a
month.
Leave the parking brake off. Put

Look for any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you
continue driving (see
on page ).
If you don’t find an obvious leak,
check the coolant level in the
radiator reserve tank (see page
). Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. After the
pressure releases, push down on
the cap, and turn it until it comes
off.
If
there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the reading
reaches the middle of the
temperature gauge or lower
befo re checking the radiato r. Start
the engine, and set the
temperature to maximum heat
(climate control to AUTO at
‘‘ ’’). Add coolant to the
radiator up to the base of the filler
neck. If you do not have the
proper coolant mixture available,
you can add plain water.
Remember to have the cooling
system drained and refilled with
the proper mixture as soon as you
can.
If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly. Put the radiator cap back on
tightly. Run the engine, and watch
the temperature gauge. If it goes
back to the H mark, the engine
needs repair (see on page ).
