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

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

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

window is almost closed. You should
always check that all passengers and
objects are away from the window
bef ore closing it. If your vehicle’s battery is
disconnected or goes dead, or the
driver’s window f use is removed, the
AUTO f unction will be disabled. The
power window system needs to be
reset af ter reconnecting the battery
or installing the f use. You should do
the f ollowing.
Any impact due to road conditions

Preparing to Drive
Driving251

When the brake pads need replacing,
you will hear a distinctive metallic
‘‘screeching’’ sound when you apply
the brakes. If you do not have the
brake pads replaced, they will begin
screeching all the time.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by downshif ting to a lower
gear and taking your f oot of f the
accelerator pedal.
Check your brakes af ter driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Since a
longer distance is needed to stop
with wet brakes, be extra cautious
and alert in your driving.
Your Acura is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. The ABS helps
you retain steering control when
braking very hard.
Put your f oot on the brake pedal only
when you intend to brake. Resting
your f oot on the pedal keeps the
brakes applied lightly, causing them
to build up heat. Heat build-up can
reduce how well your brakes work. It
also keeps your brake lights on all
the time, conf using drivers behind
you.
All f our brakes have audible brake
wear indicators.
Your brakes may sometimes squeal
or squeak when you apply them
lightly. Do not conf use this with the
brake wear indicators. The
indicators make a very audible
‘‘screeching.’’ Brake Wear Indicators
