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

However, if electronic accessories
are improperly installed, or exceed
your vehicle’s electrical system
capacity, they can interf ere with theoperation of your vehicle, or even
cause the airbags to deploy.

obscure any lights, or interf ere
with proper vehicle operation or
perf ormance.
Be sure electronic accessories do
not overload electrical circuits
(see page ).
If possible, have your dealer inspect
the f inal installation. Bef ore installing any accessory:
When properly installed, cellular
phones, alarms, two-way radios, and
low-powered audio systems should
not interf ere with your vehicle’s
computer-controlled systems, such
as the SRS and anti-lock brake
system.
Modif ying your vehicle, or installing
some non-Acura accessories, can

Improper accessories or
modifications can affect your
vehicle’s handling, stability, and
performance, and cause a
crash in which you can be hurt
or killed.
Follow all instructions in this
owner’s manual regarding
accessories and modifications.

Any object
attached to or placed on the covers
marked ‘‘SRS AIRBAG,’’ in the
center of the steering wheel and
on top of the dashboard, could
interf ere with the proper operation
of the airbags. Or, if the airbags
inf late, the objects could be
propelled inside the vehicle and
hurt someone.
If a side airbag
inflates,acupholderorotherhard
object attached on or near the
door could be propelled inside the
vehicle and hurt someone.
Covering the outside edge of a
f ront seat-back, with a non-Acura
seat cover for example, could
prevent the airbag from inflating
properly.
Removing parts f rom your vehicle,
or replacing components with non-
Acura (aftermarket) components
could seriously af f ect your vehicle’s
handling, stability, and reliability.
Some examples are:
Lowering the vehicle with an
aftermarket suspension kit that
signif icantly reduces ground
clearance can allow the
undercarriage to impact speed
bumps or other raised objects,
which could cause the airbags to
deploy.
Raising the vehicle with an
af termarket suspension kit can
af f ect the handling and stability.
Af termarket wheels, because they
are a universal design, can cause
excessive stress on suspension
components. Do not modif y your steering wheel
or any other part of your
Supplemental Restraint System.
Modif ications could make the
system inef f ective.
Larger or smaller wheels and tires
can interf ere with the operation of
your vehicle’s anti-lock brakes and
other systems.
If you plan to modif y your vehicle,
consult with your Acura dealer.
