Acura RDX 2008 Owner's Manual

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 signif icantly 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-
inf ormation display along with a
‘‘CHECK TIRE PRESSURE’’
message.Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure/TPMS
indicator may come on unexpectedly.
Driving on a signif icantly under-
inf lated tire causes the tire to
overheat and can lead to tire failure.
Under-inf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
If the tire is f lat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire (see page ).
If you think you can saf ely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure.
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is signif icantly underinf lated.
Youshouldstopandcheckyourtires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle’s tire inf ormation
placard.
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/
TPMS 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. 370

Although your tire pressure is
monitored, you must manually check
thetirepressuresmonthly.
Each tire, including the spare, should
be checked monthly when the
vehicle is cold, and set to the
recommended inf lation pressure as
specif ied on the vehicle placard and
intheowner’smanual(seepage).
Toselectthetirepressuremonitor,
press the INFO button several times
with the ignition switch in the ON
(II) position.
You will see the above display on the
multi-inf ormation display when all
tire pressures are normal.
For example, if you check and f ill
your tires in a warm area, then drive
in extremely cold weather, the tire
pressure will be lower than
measured and could be underinf lated
and cause the low tire pressure/
TPMS indicator to come on. Or, if
youcheckandadjustyourtire
pressure in cooler conditions, and
drive into extremely hot conditions,
the tire may become overinf lated.
However, the low tire pressure/
TPMS indicator will not come on if
thetiresareoverinflated.
Refer to page for tire inflation
guidelines.
If there is a problem with the TPMS,
this indicator begins to f lash. It stops
flashing after approximately 1
minute, then stays on. You will also
see a ‘‘CHECK TPMS SYSTEM’’
message on the multi-inf ormation
display (see page ).

The vehicle stability assist (VSA)
system helps to stabilize the vehicle
during cornering if the vehicle turns
more or less than desired. It also
assists you in maintaining traction
while accelerating on loose or
slippery road surf aces. It does this
by regulating the engine’s output and
by selectively applying the brakes.When VSA activates, you will see the
VSA activation indicator blink (see
page ).
If this indicator comes on while
driving, pull to the side of the road
when it is saf e, and turn of f the
engine. Reset the system by
restarting the engine. If the VSA
system indicator stays on or comes
back on while driving, have the VSA
system inspected by your dealer.
If the indicator does not come on
when the ignition switch is turned to
the ON (II) position, there may be a
problem with the VSA system. Have
your dealer inspect your vehicle as
soon as possible.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. There may also
be some noise f rom the VSA
hydraulic system. You will also see
the VSA activation indicator blink.
The VSA system cannot enhance the
vehicle’s driving stability in all
situations and does not control your
vehicle’s entire braking system. It is
still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety. You will also see a ‘‘CHECK VSA
SYSTEM’’ message on the multi-
inf ormation display if there is a
problem with the VSA system.
If the low tire pressure/TPMS
indicator comes on (see page ),
or the multi-information display
shows a ‘‘CHECK TPMS SYSTEM’’
message with the indicator flashing
(see page ), the VSA system
automatically turns on even when
the VSA system is turned of f with
the VSA OFF switch. In this case,
you cannot turn the VSA system of f
by pressing the VSA OFF switch
again.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.

This switch is under the driver’s side
vent. To turn the VSA system on and
of f , press and hold it until you hear a
beep.
When VSA is off, the VSA activation
indicator comes on as a reminder.
VSA is turned on every time you
start the engine, even if you turned it
off the last time you drove the
vehicle.Driving with varying tire or wheel
sizes may cause the VSA to
malf unction. When replacing tires,
make sure they are the same size
and type as your original tires (see
page ).
If you install winter tires, make sure
they are the same size as those that
were originally supplied with your
vehicle. Exercise the same caution
during winter driving as you would if
your vehicle was not equipped with
VSA.
In certain unusual conditions when
your vehicle gets stuck in shallow
mud or f resh snow, it may be easier
to free it with the VSA temporarily
switched of f . When the VSA system
is of f , the traction control system is
alsooff.Youshouldonlyattemptto
f ree your vehicle with the VSA of f if
you are not able to f ree it when the
VSA is on.
Immediately af ter f reeing your
vehicle, be sure to switch the VSA on
again. We do not recommend driving
your vehicle with the VSA and
traction control systems switched off.

Your vehicle has been designed
primarily to carry passengers and
their cargo. You can also use it to
tow a trailer if you caref ully observe
the load limits, use the proper
equipment, and f ollow the guidelines
in this section.
Be sure to read thesectiononpage
if you plan to tow of f paved
surf aces.
The
maximum allowable weight of the
trailer and everything in or on it
must not exceed 1,500 lbs (680 kg).
Towing a load that is too heavy can
seriously af f ect your vehicle’s
handling and perf ormance. It can
also damage the engine and
drivetrain. Theweightthatthe
tongue of a f ully-loaded trailer puts
on the hitch should be approximately
10 % of the total trailer weight. Too
much tongue load reduces f ront-tire
traction and steering control. Too
little tongue load can make the
trailer unstable and cause it to sway.

and trailer can cause a crash in
which you can be seriously hurt
or killed.
Check the loading of your
vehicle and trailer carefully
beforestartingtodrive.

To achieve a proper tongue load,
start by loading 60 % of the load
toward the front of the trailer and
40 % toward the rear, then re-adjust
the load as needed.
The maximum
allowable weight of the vehicle, all
occupants, all accessories, all cargo,
and the tongue load is 4,894 lbs
(2,220 kg).
The maximum
allowable weight of the vehicle, all
occupants, all accessories, all cargo,
and the tongue load must not exceed
2,546 lbs (1,155 kg) on the f ront axle,
and 2,381 lbs (1,080 kg) on the rear
axle. The maximum
allowable weight of the f ully loaded
vehicle and trailer is 6,394 lbs (2,900
kg)
Towing can require a variety of
equipment, depending on the size of
your trailer, how it will be used, how
much load you are towing, and
where you tow.
Discuss your needs with your trailer
sales or rental agency, and f ollow the
guidelines in this section. Also make
sure that all equipment is properly
installed and maintained, and that it
meets f ederal, state, province, and
local regulations.
If you normally pull the same load
each time you tow a trailer, you can
use a suitable scale or a special
tongue load gauge to check the
tongue load the f irst time you set up
a towing combination (a f ully loaded
vehicle and trailer), then recheck the
tongue load whenever the conditions
change.
Thebestwaytoconfirmthatall
loads are within limits is to check
them at a public scale. For public
scales in your area, check your local
phone book, or contact your trailer
dealer or rental agency for
assistance.
If you cannot get to a public scale,
you can estimate the total trailer
weight by adding the weight of your
trailer (as quoted by the
manuf acturer) with everything in or
on the trailer.

Trailer lights and equipment must
comply with f ederal, state/province,
and local regulations. Check with
your local trailer sales or rental
agencies f or the requirements in the
area where you plan to tow, and use
only equipment designed f or your
vehicle.
Acura requires that any trailer with a
total trailer weight of 1,000 lbs (455
kg) or more have its own 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.

agency f or more inf ormation on
installing electric brakes.
Any hitch used on your vehicle must
be properly bolted to the underbody.
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.
