light Acura RL 2007 Manual Online

Your vehicle is equipped with disc
brakes at all four wheels. A power
assist helps reduce the effort needed
on the brake pedal. The brake pedal
assist function increases the force
you apply to the brake pedal during
an emergency stop. When the brake
pedal assist is activated, the e-
pretensioners (if equipped) tighten
front seat belts (see page ). The
anti-lock brake system (ABS) helps
you retain steering control when
braking very hard (see page ).
Resting your f oot on the brake pedal
applies the brakes slightly. This
builds up heat, and reduces brake
ef f ectiveness and brake pad lif e. In
addition, f uel economy can be
reduced. It also keeps your brake
lights on all the time, conf using
drivers behind you. 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.
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 the brakes after 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 in your driving.
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.

The CMBS does not activate if the
speed difference between your
ve hicles is less than 10 mph (15
km/h). CMBS may also not
activate if you turn the steering
wheel to avoid the collision.
When the CMBS activates, the brake
lights also come on.
The
collision mitigation brake
system (CMBS) can assist you when
there is a possibility of your vehicle
hitting the vehicle in front of you. It
is designed to reduce the speed of
your vehicle before an unavoidable
collision occu rs and, if possible, to
alert you to a poten tial collision while
thereistimetopreventit.Hereisa
brief description of what the CMBS
can do:
When your speed is above 10 mph
(15 km/h), the CMBS radar
sensor in the front grille can sense
a vehicle ahead of you. When your
vehicle gets too close to the
ve hicle ahead of you, the system
mayactivateawarningbeep,
causing automatic application of
the brakes, and causing the
e-pretensioners to tighten the
f ront seat belts (see page ). The CMBS consists of a radar
sensor in the f ront grille, a brake
actuator in the engine compartment,
an indicator on the instrument panel,
seat belt e-pretensioners on the f ront
seats,andanon/off switchonthe
dashboard.

When you pass a low bridge at
high speed.When you approach train tracks at
the bottom of a hill and you do not
apply the brakes.Because of the road condition
(curved, winding, etc.) or the state of
your vehicle (turning angle, lane
position, etc.), CMBS can sometimes
mistake a stationary object (light
pole, traf f ic sign, etc.) as a vehicle
ahead of you and temporarily
operate. This is normal.
When you go over a sharp-edged
speed bump at high speed.
When you go over areas of
construction on the road surface.

It is possible that the pressures
shown on the multi-inf ormation
display and the pressures you
manually measure are slightly
dif f erent.
If the dif f erence is signif icant or you
cannot make the low tire pressure
indicator and message on the multi-
inf ormation display go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible.If there is a problem with the TPMS,
the multi-information display shows
a ‘‘CHECK TPMS SYSTEM’’
message.If you see this message, the tire
pressure monitor shows a ‘‘SYSTEM
FUNCTION ERROR’’ message. The
system may not be able to detect or
signal low tire pressure as intended.
Also, the tire pressure readings will
not be displayed. Have your vehicle
checked by a dealer as soon as
possible.

Always use saf ety chains when you
tow a trailer. Make sure the chains
are secured to the trailer and hitch,
and that they cross under the tongue
and can catch the trailer if it
becomes unhitched. Leave enough
slack to allow the trailer to turn
corners easily, but do not let the
chains drag on the ground.Acura recommends that any trailer
having a total weight of 1,000 lbs
(450 kg) or more be equipped with
its own electric or surge-type brakes.
If you choose electric brakes, be
sure they are electronically actuated.
Do not attempt to tap into your
vehicle’s hydraulic system. No
matter how successf ul it may seem,
any attempt to attach trailer brakes
to your vehicle’s hydraulic system
will lower braking ef f ectiveness and
create a potential hazard.Trailer lights and equipment must
comply with federal, state, and local
regulations. Check with your local
trailerdealerorrentalagencyforthe
requirements in your area, and use
only equipment designed f or your
vehicle.
Since lighting and wiring vary by
trailer type and brand, you should
have a qualified technician install a
suitable connector between the
vehicle and the trailer. Improper
equipment or installation can cause
damage to your vehicle’s electrical
system and af f ect your vehicle
warranty.

Many states and Canadian provinces
require special outside mirrors when
towing a trailer. Even if they don’t,
you should install special mirrors if
you cannot clearly see behind you, or
if the trailer creates a blind spot.

suspension, cooling system, and
lights are in good operating
condition.
All items in or on the trailer are
properly secured and cannot shif t

The low beam headlight bulbs are a
type of high voltage discharge tube.
High voltage can remain in the
ci rcuit even with the light switch off
and the key removed. Because of
this, you should not attempt to
examine or change a low beam
headlight bulb yourself. If a low
beam headlight bulb fails, take the
vehicle to your dealer to have it
replaced. Your
vehicle has halogen high beam
headlight bulbs which are also used
for the daytime running light.
Handle it by its base and protect the
glass from contact with your skin or
hard objects. If you touch the glass,
clean it with denatured alcohol and a
clean cloth.
Your
vehicle is equipped with an
automatic headlight adjusting
system that adjusts the vertical angle
of the headlights automatically.
Refer to page for more
inf ormation.
