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
as possible.

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 indicator comes on f or a f ew
seconds when you turn the ignition
switch ON (II). It will then go of f if
you have inserted a properly-coded
ignition key. If it is not a properly-
coded key, the indicator will blink
and the engine will not start (see
page ).
This indicator also blinks several
times when you turn the ignition
switch f rom ON (II) to ACCESSORY
(I) or LOCK (0).
This light normally comes on f or a
f ew seconds when you turn the
ignition switch ON (II), and when
the ignition switch is turned to
START (III). If this light comes on at
any other time, there is a problem in
theABS.If thishappens,takethe

checked. With the light on, your
vehicle still has normal braking
ability but no anti-lock. For complete

This indicator comes on when you
turn the ignition switch ON (II). It
is a reminder to check the parking
brake. A beeper sounds if you try

This meter shows the number of
miles (U.S.) or kilometers (Canada)
driven since you last reset it.
There are two trip meters: Trip A
and Trip B. Switch between these
displays by pressing the Select
button repeatedly. Each trip meter
works independently, so you can
keep track of two dif f erent distances.
When you turn the ignition switch
ON (II), what you last selected isdisplayed.
To reset a trip meter, display it, and
then press and hold the Reset button
until the number resets to ‘‘0.0’’.
Both trip meters will reset if the
vehicle’s battery goes dead or is
disconnected.
This shows the temperature of the
engine’s coolant. During normal
operation, the pointer should rise
from the bottom blue mark to about
the middle of the gauge. In severe
driving conditions, such as very hot
weather or a long period of uphill
driving, the pointer may rise to the
upper white mark. If it reaches the
red (Hot) mark, pull saf ely to the
side of the road. Turn to page f or
instructions and precautions on
checking the engine’s cooling
system.
This shows how much f uel you have.
It is most accurate when the vehicle
is on level ground. It may show
slightly more or less than the actual
amount when you are driving on
curvy or hilly roads.
The needle returns to the bottom
after you turn off the ignition. The
gauge shows the f uel level reading
immediately af ter you turn the

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
