How Your Side Curtain Airbags Work
In a moderate to severe side impact,
sensors will detect rapid acceleration
and signal the control unit to
instantly inflate the side curtain
airbag and activate the seat belt
tensioner on the driver's or the
passenger's side of the vehicle.If the impact is on the passenger's
side, the passenger's side curtain
airbag will inflate even if there are no
occupants on that side of the vehicle.
One or both side curtain airbags may
inflate in a moderate to severe frontal
collision which causes the front
airbags to deploy.
To get the best protection from the
side curtain airbags, occupants
should wear their seat belts and sit
upright and well back in their seats.
How the SRS Indicator Works
The SRS indicator alerts
you to a potential problem
with your airbags or seat belt tensioners.
When you turn the ignition switch to
the ON (II) position, this indicator
comes on briefly then goes off. This
tells you the system is workingproperly.
If the indicator comes on at any other
time, or does not come on at all, you
should have the system checked by
your dealer. For example:
● If the SRS indicator does not come
on after you turn the ignition
switch to the ON (II) position.
● If the indicator stays on after the
engine starts.
● If the indicator comes on or flashes
on and off while you drive.

If you see any of these indications,
the airbags and seat belt tensioners
may not work properly when you
need them.
Ignoring the SRS indicator can
result in serious injury or death
if the airbag systems or
tensioners do not workproperly.
Have your vehicle checked by a
dealer as soon as possible if
the SRS indicator alerts you to
a possible problem.How the Side Airbag Off IndicatorWorks
U.S. Canada
This indicator
alerts you that the
passenger's side airbag has been
automatically shut off. It does
not
mean there is a problem with your
side airbags.
When you turn the ignition switch to
the ON (II) position, the indicator
should come on briefly and then go
off (see page 61). If it doesn't come
on, stays on, or comes on while
driving without a passenger in the
front seat, have the system checked. How the Passenger Airbag Off
Indicator Works
This indicator alerts you that the
passenger's front airbag has been
shut off because weight sensors
detect about 65 lbs (29 kg) or less
(the weight of an infant or small
child) on the front passenger's seat.
It does
not meanthere is a problem
with the airbag.

Be aware that objects placed on the
front seat can cause the indicator to
come on.
If the weight sensors detect there is
no passenger in the front seat, the
airbag will be off. However, the
passenger airbag off indicator will
not come on.
The passenger airbag off indicator
may come on and off repeatedly if the
total weight on the seat is near the
airbag cutoff threshold.If an adult or teenage passenger is
riding in front, move the seat as far to
the rear as possible, and have the
passenger sit upright and wear the
seat belt properly.
If the indicator comes on with no
front seat passenger and no objects
on the seat, or with an adult riding
there, something may be interfering
with the weight sensors. Look for
and remove:
● Any items under the front
passenger's seat.
● Any object hanging on the seat or
in the seat-back pocket.
● Any object(s), such as a folded-
down back seat, that are touching
the rear of the seat-back.
If no obstructions are found, have
your vehicle checked by a dealer as
soon as possible. Airbag Service
Your airbag systems are virtually
maintenance free, and there are no
parts you can safely service.
However, you must have your
vehicle serviced if:
●
An airbag ever inflates.Any airbag
that has deployed must be
replaced along with the control
unit and other related parts. Any
seat belt tensioner that activates
must also be replaced.
Do not try to remove or replace
any airbag by yourself. This must
be done by an authorized dealer or
a knowledgeable body shop.
●
The SRS indicator alerts you to a problem.
Take your vehicle to an
authorized dealer as soon as
possible. If you ignore this
indication, your airbags may not
operate properly.

●If your vehicle has a moderate tosevere impact.
Even if your airbags
do not inflate, your dealer should
inspect the driver's seat position
sensor, the front passenger's
weight sensors, the front seat belt
tensioners, and all seat belts worn
during a crash to make sure they
are operating properly. Additional Safety Precautions
●Do not attempt to deactivate your
airbags.
Together, airbags and
seat belts provide the bestprotection.
●
Do not tamper with airbag components or wiring for any
reason.
Tampering could cause
the airbags to deploy, possibly
causing very serious injury.
●
Do not expose the front passenger's seat-back to liquid.
If
water or another liquid soaks into
a seat-back, it can prevent the side
airbag cutoff system from workingproperly. ●
Do not remove or modify a front
seat without consulting your
dealer.
This could make the
driver's seat position sensor or the
front passenger's weight sensors
ineffective. If it is necessary to
remove or modify a front seat to
accommodate a person with
disabilities, first contact Honda
Automobile Customer Service at
(800) 999-1009.

Carrying Cargo in the Passenger Compartment● Store or secure all items that could
be thrown around and hurt
someone during a crash.
● Be sure items placed on the floor
behind the front seats cannot roll
under the seats and interfere with
the driver's ability to operate the
pedals, the proper operation of the
seats, or proper operation of the
sensors under the seats.
● Keep the upper and lower glove
boxes closed while driving. If it is
open, a passenger could injure
their knees during a crash or
sudden stop. ●
If you fold the rear seats up or
down, tie down items that could be
thrown about the vehicle during a
crash or sudden stop. Also, keep
all cargo below the bottom of the
windows. If it is higher, it could
interfere with the proper operation
of the side curtain airbags. Carrying Cargo in the Cargo Area
● Distribute cargo evenly on the
floor of the cargo area, placing the
heaviest items on the bottom and
as far forward as possible. Tie
down items that could be thrown
about the vehicle during a crash or
sudden stop.
● Do not stack items higher than the
back of the rear seats. They can
block your view and be thrown
around the vehicle during a crash.
● If you carry large items that
prevent you from closing the
tailgate, exhaust gas can enter the
passenger area. To avoid the
possibility of carbon monoxide
poisoning, follow the instructions
on page 53.

U.S. models only
Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.
Each tire has its own pressure sensor
(not including the spare tire). If the
air pressure of a tire becomes
significantly low, the sensor in that
tire immediately sends a signal that
causes the low tire pressure indicator
to come on.
Low Tire Pressure Indicator
When the low tire pressure indicator
is on, one or more of your tires is
significantly underinflated. You
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure as indicated on
the vehicle's tire information placard.
If you think you can safely drive a
short distance to a service station,
proceed slowly, and inflate the tire to
the recommended pressure shown
on the driver's doorjamb.
If the tire is flat, or if the tire pressure
is too low to continue driving, replace
the tire with the compact spare tire
(see page 284). If you cannot make the low tire
pressure indicator go out after
inflating the tires to the specified
values, have your dealer check the
system as soon as possible.
Driving on a significantly under-
inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
Because tire pressure varies by
temperature and other conditions,
the low tire pressure indicator may
come on unexpectedly.

Changing a Tire with TPMS
If you have a flat tire, the low tire
pressure indicator will come on.
Replace the flat tire with the compact
spare tire (see page 284).
Each wheel (except the compact
spare tire wheel) is equipped with a
tire pressure sensor mounted inside
the tire behind the valve stem. You
must use TPMS specific wheels. It is
recommended that you always have
your tires serviced by your dealer or
qualified technician.
After you replace the flat tire with the
compact spare tire, the low tire
pressure indicator stays on. This is
normal; the system is not monitoring
the spare tire pressure. Manually
check the spare tire pressure to be
sure it is correct. After several miles
(kilometers) driving with the
compact spare tire, the TPMS
indicator comes on and the low tire
pressure indicator goes off.The low tire pressure indicator or the
TPMS indicator will go off, after
several miles (kilometers) driving,
when you replace the spare tire with
the specified regular tire equipped
with the tire pressure monitorsensor.
Never use a puncture-repairing agent
in a flat tire. If used, you will have to
replace the tire pressure sensor.
Have the flat tire repaired by your
dealer as soon as possible.As required by the FCC: This device

Exhaust Emissions Controls
The exhaust emissions controls
include four systems: PGM-FI,
ignition timing control, exhaust gas
recirculation, and three way catalytic
converter. These four systems work
together to control the engine's
combustion and minimize the
amount of HC, CO, and NOx that
come out the tailpipe. The exhaust
emissions control systems are
separate from the crankcase and
evaporative emissions controlsystems.PGM-FI System
The PGM-FI system uses sequential
multiport fuel injection. It has three
subsystems: air intake, engine
control, and fuel control. The
powertrain control module (PCM) in
automatic transmission vehicles or
the engine control module (ECM) in
manual transmission vehicles uses
various sensors to determine how
much air is going into the engine. It
then controls how much fuel to inject
under all operating conditions.
Ignition Timing Control System
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
Exhaust Gas Recirculation (EGR)System
The exhaust gas recirculation (EGR)
system takes some of the exhaust gas
and routes it back into the intake
manifold. Adding exhaust gas to the
air/fuel mixture reduces the amount
of NOx produced when the fuel is burned.
Three Way Catalytic Converter
The three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine's exhaust
to carbon dioxide (CO 2), nitrogen
(N 2), and water vapor.
Replacement Parts
The emissions control systems are
designed and certified to work
together in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Honda replacement parts or their
equivalent for repairs. Using lower
quality parts may increase the
emissions from your vehicle.
The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for moreinformation.
