located under both of the f ront
passenger’s seat rails. These sensors
monitor the weight on the seat at the
seat cushion, seat-back, seat-back
pocket, and seat rails.
If the total weight on the seat is
about65lbs(30kg)orless,the
system shuts of f the f ront passenger’s

If the light 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 light does not
come on after you turn the ignition
switch to ON (II).
If the light stays on after the
engine starts.
If the light comes on or f lashes on
andoff whileyoudrive.
The SRS indicator light
alerts you to a potential
problem with your f ront airbags and
automatic seat belt tensioners.
This light will also alert you to a
potential problem with your side
airbags, passenger’s side airbag
automatic cutoff system (see page ), or the driver’s seat position
sensor and the f ront passenger’s
weight sensors (see pages and ).
When you turn the ignition ON (II),
this indicator will light brief ly then
go out. This tells you that the system
is working properly. If you see any of these indications,
your f ront or side airbags may not
deploy, your passenger’s side airbag
automatic cutoff system may not
work properly, your seat belt
tensioners may not work, or the
sensors under the f ront seats may
not work properly when you need
them. See your Acura dealer as soon

Ignoring the SRS indicator light
can result in serious injury or
death if the airbags, cutoff
system, or tensioners do not
work properly.
Have your vehicle checked by a
dealer as soon as possible if
the SRS light alerts you to a
potential problem.

This light alerts you that the f ront
passenger’s airbag is shut of f .If the light is on, it does not mean
there is a problem with the f ront
passenger’s airbag. If there is a
problem in the weight sensors, the
SRS indicator in the instrument
panel comes on. In this case, the
passenger airbag cutof f indicator
turns of f , and the f ront passenger’s
airbag will inflate during a crash.
To reduce the chance of airbag-
caused injuries, the system shuts of f
the f ront passenger’s airbag when
the total weight on the f ront
passenger’s seat is about 65 lbs
(30 kg) or less. The passenger
airbag cutoff indicator comes on to
remind you the f ront passenger’s
airbag will not inf late during a crash.If there is no passenger in the f ront
passenger’s seat, this indicator does
not come on, however the system
shuts of f the f ront passenger’s
airbag.
If this indicator comes on with no
passenger in the f ront passenger’s
seat,orwithanadultintheseat,
there may be a problem in the
advanced airbag system. Have the
vehicle checked by the dealer as
soon as possible.
This indicator may come on or of f
repeatedly, if some objects are put

To ensure the f ront passenger’s seat
weight sensors keep the passenger’s
airbag activated when an adult or
large child weighing about 65 lbs/
30 kg or more sits in the front
passenger’s seat, do not allow
anything to decrease the weight on
the seat. This includes, but is not
limited to, these examples:Rear passengers pushing up the
frontpassenger’sseatwiththeir
f eet.
Front passenger’s seat f orcibly
pushed up by luggage or other
items placed under it.
Front passenger’s seat f orcibly
moved backward into luggage or
other items placed behind it. If a passenger is tall enough to use
the seat belt and sit properly, but the
passenger airbag cutof f indicator
comes on and of f repeatedly, we
recommend that the passenger sits
in a rear seat. If the passenger must
sit on the f ront seat, move the seat
as far to the rear as possible, have
the passenger sit upright, and make
sure the seat belt is worn securely.
To ensure the f ront passenger’s seat
weight sensors keep the passenger’s
airbag deactivated when an infant or
small child weighing about 65 lbs/
30 kg or less sits in the f ront
passenger’s seat, do not allow
anything to increase the weight on
the seat. This includes, but is not
limited to, these examples:
Rear passengers pushing or
pulling the f ront passenger’s seat-
back or pushing the seat rails with
their f eet.
Heavy items placed in the f ront
passenger’s seat-back pocket.

Together, airbags and
seat belts provide the best
protection.
Tampering could cause
the airbags to deploy, possibly
causing very serious injury.
If rain or spilled water
soaks into a seat-back, it can
prevent the side airbag system
f rom working properly. Improperly
replacing or covering f ront seat-
back covers can prevent your side
airbags f rom inf lating during a
collision.

The condition of your vehicle and
your driving habits are the two most
important things that affect the fuel
mileage you get.
Always maintain your vehicle accord-
ing to the maintenance schedule.
This will keep it in top operating
condition.A cold engine uses more f uel than a
warm engine. It is not necessary to
‘‘warm-up’’ a cold engine by letting it
idle f or a long time. You can drive
away in about a minute, no matter
how cold it is outside. The engine
will warm up f aster, and you get
better f uel economy. To cut down on
the number of ‘‘cold starts,’’ try to
combine several short trips into one.
You can improve f uel economy by
driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more f uel.
Always drive in the highest gear that
allows the engine to run and acceler-
ate smoothly.
Depending on traf f ic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your vehicle uses extra f uel. Use the
cruise control, when appropriate, to
increase f uel economy.
The air conditioning puts an extra
load on the engine which makes it
usemorefuel.Turnoff theA/Cto
cut down on air conditioning use.
Use the f low-through ventilation
when the outside air temperature is
moderate.
In winter, the build-up of snow on
your vehicle’s underside adds weight
and rolling resistance. Frequent
cleaning helps your f uel mileage and
reduces the chance of corrosion. An important part of that mainte-
nance is the (see page ). For
example, an underinf lated tire
causes more ‘‘rolling resistance,’’
which uses f uel. It also wears out
f aster, so check the tire pressure at
least monthly. 305

Your vehicle has several convenient
storage areas so you can stow cargo
saf ely.
The glove box, and the pockets in
the f ront doors and seat-backs, are
designed f or small, lightweight items.
The cargo area is intended f or larger,
heavier items. The second and third
row seats can be f olded f lat to allow
you to carry more cargo or longer
items.
However, carrying too much cargo,
or improperly storing it, can af f ect
your vehicle’s handling, stability,
stopping distance, and tires, and
make it unsaf e. Bef ore carrying any
type of cargo, be sure to read the

Following are the steps f or
determining the correct cargo and
luggage load limit.
The resulting f igure equals the
available amount of cargo and
luggage load capacity.
The maximum load limit f or your
vehicle is 1,158 lbs (525 kg). This
f igure includes the total weight of all
occupants, cargo, accessories, and
the tongue weight if you are towing a
trailer.
Locate the statement, ‘‘the
combined weight of occupants and
cargo should never exceed 1,158
lbs (525 kg)’’ on your vehicle’s
placard (on the driver’s doorjamb).
Determine the combined weight
of the driver and passengers that
will be riding in your vehicle.
(Seven is the seating capacity of
your vehicle.) Subtract the combined weight of
the driver and passengers f rom
1,158 lbs (525 kg).
For example, if there will be f ive 150
lbs (70 kg) occupants in your vehicle,
the amount of available cargo and
luggage load capacity is 408 lbs (175
kg).
5 150 lbs (70 kg) = 750 lbs (350
kg)
1,158 lbs (525 kg) 750 lbs (350 kg)
= 408 lbs (175 kg) If your vehicle will be towing a
trailer, load f rom your trailer will
be transf erred to your vehicle.
Consult this manual to determine
how this reduces the available
cargo and luggage load capacity of
your vehicle.
Determine the combined weight
of accessories, luggage, and cargo
beingloadedinthevehicle.The
weight may not saf ely exceed the
available cargo and luggage load
capacity calculated in step 4 [408
