Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes significantly low, the sensor
in that tire immediately sends a
signal that causes the low tire
pressure/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
information display along with a
‘‘CHECK TIRE PRESSURE ’’
message.
Low Tire Pressure/TPMS
Indicator
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is significantly underinflated.
You should stop and check your tires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle's tire information
placard.
It is possible that the pressures
shown on the multi-information
display and the pressures you
manually measure are slightly
different.
If the difference is significant or you
cannot make the low tire pressure/
TPMS indicator and message on the
multi-information display go out after
inflating the tires to the specified
values, have your dealer check the
system as soon as possible. If you think you can safely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure.
If the tire is flat, or if the tire pressure
is too low to continue driving, replace
the tire with the compact spare tire
(see page 454).
Driving on a significantly under-
inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
Because tire pressure varies by
temperature and other conditions,
the low tire pressure/TPMS
indicator may come on unexpectedly.

Trailer BrakesAcura recommends that any trailer
with a total trailer weight of 1,000 lbs
(450 kg) or more has its own brakes.
There are two common types of
trailer brakes: surge and electric.
Surge brakes are common for boat
trailers, since the brakes will get wet.
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
successful it may seem, any attempt
to attach trailer brakes to your
vehicle's hydraulic system will lower
braking effectiveness and create a
potential hazard.
See your trailer dealer or rental
agency for more information on
installing electric brakes.
Trailer LightsTrailer lights and equipment must
comply with federal, provincial,
territorial, and local regulations.
Check with your local trailer sales or
rental agencies for the requirements
in the area where you plan to tow,
and use only equipment designed for
your vehicle.
Your vehicle has a trailer lighting
connector located under the right
side tool case in the cargo area. Refer
to the drawing above for the wiring
color code and purpose of each pin.
