2005 Acura MDX spare wheel

The appropriate tire indicator and
low tire pressure indicator comes on
if a tire becomes signif icantly
underinf lated. Follow the
instructions under ‘‘Low Tire
Pressure Indicator’’.The indicator comes on and stays on
if there is a problem with the tire
pressure monitoring system.
Af ter you replace the f lat tire, the
Low Tire Pressure indicator stays on.
This is normal; the system is not
monitoring the spare tire pressure.
Manually check the spare tire
pressure to be sure it is correct.
If this happens, the system will shut
of f and no longer monitor tire
pressures. Have the system checked
by your dealer as soon as possible. Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specif ic wheels. It is
recommended that you always have
your tires serviced by your dealer or
qualif ied technician.
Never use a puncture-repairing agent
in a f lat tire. If used, you will have to
replace the tire pressure sensor.

If you have a f lat tire, the low tire

Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.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 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.
When VSA is off, the VSA activation
indicator comes on as a reminder.
If the indicator does not come on
when the ignition switch is turned to
ON(II),theremaybeaproblem
with the VSA system. Have your
dealer inspect your vehicle as soon
as possible.
This switch is under the lef t vent.
Press it to turn the VSA system on
and off. 255

Acura requires that any trailer with a
total trailer weight of 1,000 lbs (455
kg) or more have its own brakes.
There are two common types of
trailer brakes: surge and electric.
Surge brakes are common f or boat
trailers, since the brakes will get wet.
If you choose electric brakes, be
sure they are electrically 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 brake manuf acturer f or
more inf ormation on installing
electric brakes.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.
This device is recommended if your
trailer tends to sway. Your trailer
maker can tell you what kind of sway
control you need and how to install it.
Many states and provinces require
special exterior 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.When towing a trailer, we
recommend that you carry a f ull-size
spare wheel and tire for your vehicle
and trailer. See page f or proper
tire size, page f or how to store a
full size wheel and tire, and page
f or inf ormation on changing a
flat tire.
Remember to unhitch the trailer
bef ore changing a f lat. Ask your
trailer sales or rental agency where
and how to store the trailer’s spare
tire. 255

Use the compact spare tire as a
temporary replacement only. Get
your regular tire repaired or replaced,
and put it back on your vehicle as
soon as you can.
Check the inf lation pressure of the
compact spare tire every time you
check the other tires. It should be
inf lated to:
Follow these precautions:Never exceed 50 mph (80 km/h)
under any circumstances.
This tire gives a harsher ride and
less traction on some road sur-
f aces. Use greater caution while
driving. Do not mount snow chains on a
compact spare.
Do not use the compact spare tire
if you are towing a trailer.
Do not use your compact spare
tire on another vehicle unless it is
thesamemakeandmodel.
Replace the tire when you can see
the tread wear indicator bars. The
replacement should be the same size
and design tire, mounted on the
same wheel. The spare tire is not
designed to be mounted on a regular
wheel, and the spare wheel is not
designed f or mounting a regular tire.
