2007 Acura RDX traction control

Because your vehicle rides higher
off the ground, it has a high center
of gravity that can cause it to roll
over if you make abrupt turns. Utility
vehicl es have a signifi cantly higher
roll over rate than other types of
ve hicles.
Your
vehicle has higher ground
clearance that allows you to travel
over bumps, obstacles, and rough
terrain. It also provides good
visibility so you can anticipate
problems earlier. To
prevent rollovers or loss of
control:
Take corners at slower speeds
than you would with a passenger
vehicle.
Avoid sharp turns and abrupt
maneuvers whenever possible.
Do not modify your vehicle in any
way that would raise the center of
gravity.
Do not carry heavy cargo on the
roof. Your
vehicle is equipped with a
super handling-all wheel drive (SH-
AWD) system. When the system
senses a loss of one or more wheel
traction, it automatically transfers
some power to the other wheels.
This gives you better traction and
mobility.
You still need to exercise the same
care when accelerating, steering, and
brakingthatyouwouldinatwo-
wheel drive vehicle.

The VSA system cannot enhance the
vehicle’s driving stability in all
situ ations 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.
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 surfaces. It does this
by regulating the engine’s output and
by selectively applying the brakes.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. You will also see
the VSA activation indicator blink. 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 safe, and turn off 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 deale r.
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 vehic le as
soon as possible. You will also see a ‘‘CHECK VSA
SYSTEM’’ message on the multi-
inf ormation display (see page ).
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.
When you put a spare tire on the
wheel, TPMS indicator or ‘‘CHECK
TPMS SYSTEM’’ message
(depending on the models) may
come on. When the indicator or
message is on, you are unable to turn
of f the VSA system with the VSA
OFF switch.

This switch is under the driver’s side
vent. To turn the VSA system on and
off, 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 turn ed it
off the last time you drove the
vehicle. Driving
with varying tire or wheel
sizes may cause the VSA to
malfunction. 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 carefully observe
the load limits, use the proper
equipment, and follow the guidelines
in this section.
Be sure to read the sectiononpage
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.

Exceeding any load limit or

The tires on your vehicle meet all
U.S. Federal Saf ety Requirements.
All tires are also graded f or
treadwear, traction, and temperature
perf ormance according to
Department of Transportation
(DOT) standards. The f ollowing
explains these gradings.
Quality grades can be f ound where
applicable on the tire sidewall
between the tread shoulder and the
maximum section width. For
example: The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specif ied government
test course. For example, a tire
graded 150 would wear one and one-
half (1 1/2) times as well on the
government course as a tire graded
100. The relative perf ormance of
tires depends upon the actual condi-
tions of their use, however, and may
depart signif icantly f rom the norm
due to variations in driving habits,
service practices, and dif f erences in
road characteristics and climate.The traction grades, f rom highest to
lowest, are AA, A, B, and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on
specif ied government test surf aces
of asphalt and concrete. A tire
marked C may have poor traction
perf ormance.
Warning: The traction grade
assignedtothistireisbasedon
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.
All passenger car tires must conf orm
to Federal Saf ety Requirements in
addition to these grades.
