Help assure your vehicle’s f uture
reliability and perf ormance by paying
extra attention to how you drive
during the f irst 600 miles (1,000 km).
During this period:Avoid full-throttle starts and rapid
acceleration.
Avoidhardbrakingforthefirst
200 miles (300 km).
Do not change the oil until the
scheduled maintenance time.
You should also f ollow these
recommendations with an
overhauled or exchanged engine, or
when the brakes are replaced. Do not tow a trailer. In addition, in order to maintain good
perf ormance, f uel economy, and
emissions control, we strongly
recommend, in areas where it is
available, the use of gasoline that
does NOT contain manganese-based
f uel additives such as MMT.
Your vehicle is designed to operate
on premium unleaded gasoline with a
pump octane of 91 or higher. If this
octane grade is unavailable, regular
unleaded gasoline with a pump
octane of 87 or higher may be used
temporarily. The use of regular
unleaded gasoline can cause metallic
knocking noises in the engine and
will result in decreased engine
perf ormance. The long-term use of
regular-grade gasoline can lead to
engine damage. We recommend using quality
gasolines containing detergent
additives that help prevent fuel
system and engine deposits.
Use of gasoline with these additives
may adversely af f ect perf ormance,
and cause the malfunction indicator
lamp on your instrument panel to
come on. If this happens, contact
your authorized dealer f or service.

Although non-Acura accessories may
f it on your vehicle, they may not
meet f actory specif ications, and
could adversely af f ect your vehicle’s
handling and stability.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 your airbags, anti-lock brakes, and
tire pressure monitoring system.Bef ore installing any accessory:
Make sure the accessory does not
obscure any lights, or interf ere
with proper vehicle operation or
perf ormance.
Be sure electronic accessories do
not overload electrical circuits
(see page ) or interf ere with
proper operation of your vehicle.
Bef ore installing any electronic
accessory, have the installer
contact your dealer for assistance.
If possible, have your dealer

Removing parts f rom your vehicle,
or replacing components with non-
Acura components could seriously
af f ect your vehicle’s handling,
stability, and reliability.
Herearesomeexamples:Lowering the vehicle with a non-
Acura suspension kit that
signif icantly reduces ground
clearance can allow the
undercarriage to hit speed bumps
or other raised objects, which
could cause the airbags to deploy.
Raising your vehicle with a non-
Acura suspension kit can af f ect
the handling and stability. Non-Acura wheels, because they
are a universal design, can cause
excessive stress on suspension
components and will not be
compatible with the tire pressure
monitoring system (TPMS).
Larger or smaller wheels and tires
can interf ere with the operation of
your vehicle’s anti-lock brakes and
other systems.
Modif ying your steering wheel or
any other part of your vehicle’s
safety features can make the
systems inef f ective.
If you plan to modif y your vehicle,
consult your dealer.

Always use the parking brake when
you park your vehicle. Make sure
the parking brake is set f irmly, or
your vehicle may roll if it is parked
on an incline.Make sure the moonroof and the
windows are closed.
If the vehicle is f acing uphill, turn
the front wheels away from the
curb.
If the vehicle is f acing downhill,
turn the front wheels toward the
curb.
Check the indicator on the
instrument panel to verif y that the
security system is set.
Make sure the parking brake is
f ully released bef ore driving away.
Driving with the parking brake
partially set can overheat or
damage the rear brakes.
Set the parking brake bef ore you put
the transmission in Park. This keeps
the vehicle from moving and putting
pressure on the parking mechanism
in the transmission.
Turn of f the lights.
Place any packages, valuables, etc.
in the cargo area or take them
with you.
Lock the doors and the tailgate.
Never park over dry leaves, tall
grass, or other f lammable
materials. The hot three way
catalytic converter could cause
these materials to catch on fire.

Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist using negative pressure
generated by the engine and the
electric vacuum pump helps reduce
the ef f ort needed on the brake pedal.
The anti-lock brake system (ABS)
helps you retain steering control
when braking very hard.All f our brakes have audible brake
wear indicators.
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal f or
the brakes to occasionally squeal or
squeak when you apply them.
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness
and reduces brake pad life. In
addition, f uel economy can be
reduced. It also keeps your brake
lights on all the time, conf using
drivers behind you.
When the electric vacuum pump is in
operation, it makes some mechanical
noises come f rom the engine
compartment. This is normal.
When you drive in cold weather or
thinner air at high altitude, the
electric vacuum pump operates more
f requently af ter the engine is started.
For more inf ormation about the
electric vacuum pump, see page . 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 taking your f oot of f the
accelerator and downshif ting to a
lower gear.
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. Be extra
cautious and alert in your driving.

The anti-lock brake system (ABS)
helpspreventthewheelsfrom
locking up, and helps you retain
steering control by pumping the
brakes rapidly, much f aster than a
person can do it.
The electronic brake distribution
(EBD) system, which is part of the
ABS, also balances the f ront-to-rear
braking distribution according to
vehicle loading.You will f eel a pulsation in the brake
pedal when the ABS activates, and
you may hear some noise. This is
normal: it is the ABS rapidly
pumpingthebrakes.Ondry
pavement, you will need to press on
thebrakepedalveryhardbeforethe
ABS activates. However, you may
feel the ABS activate immediately if
you are trying to stop on snow or ice.
If this indicator comes on, the anti-
lock f unction of the braking system
has shut down. The brakes still work
like a conventional system, but
without anti-lock. You should have
your dealer inspect your vehicle as
soon as possible.
Let the ABS work f or you by always
keeping f irm, steady pressure on the
brake pedal. This is sometimes
ref erred to as ‘‘stomp and steer.’’ You will also see a ‘‘CHECK ABS
SYSTEM’’ message on the multi-
inf ormation display (see page ).
If the indicator comes on while
driving, test the brakes as instructed
on page .
