2007 Acura TSX Owner's Manual

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.
Wh en the VSA system indicator
comes on, you will also see a
‘‘CHECK VSA SYSTEM’’ message
on the multi-information display.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.
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.
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 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.
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. 65

Driving with varying tire or wheel
sizes may cause the VSA to
malfunction. When replacing tires,
make sure they are of the same size
and type as your original tires (see
page ).
Deactivate the VSA system if you
need to drive with the compact spare
tire installed (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.
This switch is under the lef t vent.
Press it to turn the vehicle stability
assist system on and of f .
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.
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.The
maximum allowable weight of the
trailer and everything in or on it
must not exceed 1,000 lbs (450 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. The weight that
the 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 front-tire traction and
steering control. Too little tongue
load can make the trailer unstable
and cause it to sway.

Exceeding any load limit or
improperly loading your vehicle
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 best way to conf irm that vehicle
and trailer weights are within limits
is to have them checked at a public
scale.
Using a suitable scale or a special
tongue load gauge, 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.
The maximum allowable weight of
the vehicle axles is:

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.
See your trailer dealer or rental
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.
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.
Towing generally requires a variety
of supplemental equipment,
depending on the size of your trailer,
how much load you are towing, and
where you tow. To ensure the best
quality, we recommend that you
purchase Acura equipment
whenever possible.
Discuss your needs with your trailer
sales or rental agency, and f ollow the
guidelines in the rest of this section.
Also make sure that all equipment is
properly installed and maintained,
and that it meets f ederal, state,
province, and local regulations. T owing Equipment and

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.Ask your trailer sales or rental
agency if any other items are
recommended or required f or your
towing situation.
Trailer lights and equipment must
comply with f ederal, state, province,
and local regulations. Check the
requirements f or the areas where
you plan to tow, and use only
equipment designed f or your vehicle.
Since lighting and wiring vary by
trailer type and brand, you should
have a qualif ied 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.

When preparing to tow, and before
driving away, be sure to check the
following: Al
ways drive slowly and have
someone guide you when backing up.
Grip the of the steering
wheel; then turn the wheel to the left
to get the trailer to move to the left,
andturnthewheelrighttomovethe
trailer to the right.
Follow all normal precautions when
parking, including firmly setting the
parking brake and putting the
transmission in Park (automatic) or
in first or reverse (manual). Also,
place wheel chocks at each of the
trailer’s tires.
Your
vehicle tires and spare are
properly inflated (see page ),
and the trailer tires and spare are
inflated as recommended by the
trailer maker.
Crosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause the trailer to
sway. When being passed by a large
vehicle, keep a constant speed, and
steer straight ahead. Do not try to
make quick steering or braking
corrections.
The
vehicle has been properly
serviced, and the suspension,
cooling system, and lights are in
good operating condition.
All weights and loads are within
limits (see pages and ).
Thehitch,safetychains,andany
other attachments are secure.
All items in or on the trailer are
properly secured and cannot shif t

The added weight, length, and
height of a trailer will af f ect your
vehicle’s handling and perf ormance,
so driving with a trailer requires
some special driving skills and
techniques.Maketurnsmoreslowlyandwider

vehicle misses. Allow more time and
distance f or braking. Do not brake or
turn suddenly as this could cause the
trailer to jackknif e or turn over.
When climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, turn the air
conditioning of f , reduce speed and, if
necessary, pull to the side of the
road to let the engine cool.
If the automatic transmission shifts
f requently while going up a hill, shif t
to D .If you must stop when f acing uphill,
use the f oot brake or parking brake.
Do not try to hold the vehicle in
place by pressing on the accelerator,
as this can cause the automatic
transmission to overheat.
When driving down hills, reduce
your speed, and shif t down to second
gear. Do not ‘‘ride’’ the brakes, and
remember, it will take longer to slow

Drive slower than normal in all
driving situations, and obey posted
speed limits f or vehicles with trailers.
If you have an automatic
transmission, use D position when
towing a trailer on level roads. D is
the proper shif t lever position to use
when towing a trailer in hilly terrain.
