tires Acura MDX 2009 User Guide

To see the inflation pressures of all
four tires, press the SEL/RESET
button. The display changes as
shown above.
Each tire pressure is shown in PSI
(U.S. models) or in kPa (Canadian
models).
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.
U.S. model
Canadian model
This shows that front left tire
is losing pressure.

If any of the tires has low pressure,
the tire pressure monitor also shows
the above message to warn you
about the low tire pressure when you
select the display by pressing the
INFO button several times.
Following this display, press the
SEL/RESET button to see each tire
pressure.
When you continue driving after
installing the spare tire, you will also
see this message on the multi-
information display.
If there is a problem with the TPMS,
the tire pressure monitor shows a
‘‘SYSTEM FUNCTION ERROR’’
message and the tire pressure
readings are not displayed. If this
happens, you will first see a system
warning message ‘‘CHECK TPMS
SYSTEM ’’on the multi-information
display. TPMS System Failure
If there is a problem with the TPMS,
you will see the above message on
the multi-information display.
If you see this message, the system
is off and is not monitoring the tire
pressures. Have the system checked
by your dealer as soon as possible.
Also, the low tire pressure/TPMS
indicator begins to flash, then stays
on (see page352).

If the low tire pressure/TPMS
indicator comes on, or the multi-
information display shows a‘‘CHECK
TPMS SYSTEM ’’message, the VSA
system automatically turns on even
when the VSA system is turned off
by pressing the VSA OFF switch
(see page360).If this happens, you
cannot turn the VSA system off by
pressing the VSA OFF switch again.
When you restart the vehicle with
the compact spare tire, the TPMS
system message will also be
displayed on the multi-information
display after several miles
(kilometers) driving.
Changing a Tire with TPMS
If you have a flat tire, the low tire
pressure/TPMS and tire monitor
indicators will come on. Replace the
indicated flat tire with the compact
spare tire (see page425). After the flat tire is replaced with the
spare tire, the low tire pressure/
TPMS indicator stays on while
driving. After several miles
(kilometers) driving, this indicator
begins to flash, then stays on again.
You will also see a
‘‘CHECK TPMS
SYSTEM ’’message on the multi-
information display. This is normal;
the system cannot monitor the spare
tire pressure. Manually check the
spare tire pressure to be sure it is
correct. This indicator and the warning
message on the multi-information
display will go off, after several miles
(kilometers) driving, when the spare
tire is replaced with the specified
regular tire equipped with the tire
pressure monitor sensor.
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specific wheels. It is
recommended that you always have
your tires serviced by your dealer or
a qualified technician.
Never use a puncture-repairing agent
in a flat tire. If used, you will have to
replace the tire pressure sensor.
Have the flat tire repaired by your
dealer as soon as possible.

VSA and Tire Sizes
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
page419).
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.
U.S. Sport Packages and Canadian ElitemodelsThe active damper system is always
on, constantly adjusting your
vehicle's dampers to the best settings
for current road conditions along
with vehicle speed and handling
inputs.
The system uses electrically
controlled dampers to enhance
handling precision, vehicle
composure, tire to road adhesion and
rough road ride comfort isolation.
The system reacts to inputs from
various electronic sensors to give
exactly the right amount of
suspension damping to provide
optimal ride comfort and handling. The system provides two selectable
modes.
Sport mode: The system prioritizes
handling response, vehicle body
control and tire-to-road adhesion to
allow for higher performance
handling.
Comfort mode: The system
prioritizes road isolation to allow for a
more comfortable ride.
Either mode can be used in any type
of operating conditions.

Use this illustration to identify each
terminal in the trailer brake
controller connector.
Safety ChainsAlways use safety 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.Sway ControlThis 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.Trailer MirrorsMany 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.
Spare TiresWhen towing a trailer, we
recommend that you carry a full-size
spare wheel and tire for your vehicle
and trailer. See page419for proper
tire size, page425for how to store a
full size wheel and tire, and page425
for information on changing a flat
tire.
Remember to unhitch the trailer
before changing a flat. Ask your
trailer sales or rental agency where
and how to store the trailer's spare
tire.

Pre-Tow Checklist
When preparing to tow, and before
driving away, be sure to check the
following:●The vehicle has been properly
serviced, and the suspension and
the cooling system are in good
operating condition.●The trailer has been properly
serviced and is in good condition.●All weights and loads are within
limits.●The hitch, safety chains, and any
other attachments are secure.●All items on and in the trailer are
properly secured and cannot shift
while you drive.
●The lights and brakes on your
vehicle and the trailer are working
properly.●Your vehicle tires and spare are in
good condition and properly
inflated.●The trailer tires and spare are in
good condition and inflated as
recommended by the trailer
maker.Driving Safely With a Trailer
The added weight, length, and
height of a trailer will affect your
vehicle's handling and performance,
so driving with a trailer requires
some special driving skills and
techniques.
For your safety and the safety of
others, take time to practice driving
maneuvers before heading for the
open road, and follow the guidelines
in this section.

Driving on HillsWhen climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, turn the air
conditioning off, reduce speed and, if
necessary, pull to the side of the road
to let the engine cool.
If the transmission shifts frequently
while going up a hill, shift to D
3.
If you must stop when facing uphill,
use the foot 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 shift down to D3.Do
not ‘‘ride ’’the brakes. Remember, it
takes longer to slow down and
stop when towing a trailer.
Handling Crosswinds and BuffetingCrosswinds 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.Backing UpAlways drive slowly and have
someone guide you when backing
up. Grip the
bottom
of the steering
wheel, then turn the wheel to the left
to get the trailer to move to the left.
Turn the wheel to the right to move
the trailer to the right.
ParkingFollow all normal precautions when
parking, including putting the
transmission in Park and firmly
setting the parking brake. Also, place
wheel chocks at each of the trailer's
tires.
Retrieving a BoatIf the vehicle tires slip when
retrieving a boat from the water,
keep the transmission in the D
position and do not use the
sequential sport shift mode. This
prevents the transmission damage.
Towing Your Vehicle
Your vehicle is not designed to be
towed behind a motor home. If your
vehicle needs to be towed in an
emergency, see page446.

Check Out Your Vehicle
Before you leave the pavement, be
sure to do all scheduled maintenance
and service, and inspect your vehicle
for any problems. Pay special
attention to the condition of the tires,
and check the tire pressures.
After you return to the pavement,
carefully inspect your vehicle to
make sure there is no damage that
could make driving it unsafe.
Recheck the condition of the tires
and the tire pressures.
Remember
The route presents limits (too steep
or bumpy roads). You have limits
(driving skill and comfort). And your
vehicle has limits (traction, stability,
and power).
Driving off-highway can be
hazardous if you fail to recognize
limits and take the proper
precautions.Accelerating and Braking
For better traction on all surfaces,
accelerate slowly and gradually build
up speed. If you try to start too fast
on wet soil, mud, snow, or ice, you
might not have enough traction to
get underway, and you may dig
yourself a hole. Starting with the shift
lever in the D position will help you
have a smoother start on snow or ice.
Keep in mind that you will usually
need more time and distance to
brake to a stop on unpaved surfaces.
Avoid hard braking. Do not
‘‘pump ’’
the brakes; let the anti-lock braking
system pump them for you.
Avoiding Obstacles
Debris in the road can damage your
suspension or other components.
Because your vehicle has a high
center of gravity, driving over a large
obstacle, or allowing a wheel to drop
into a deep hole can cause your
vehicle to tip or roll over. Driving on Slopes
If you can't clearly see all conditions
or obstacles on a slope, walk the
slope before you drive on it. If you
have any doubt whether or not you
can safely drive on the slope, don't
do it. Find another route.
If you are driving up a hill and find
that you cannot continue,
do not try to
turn around.
Your vehicle could roll
over. Slowly back down the hill,
following the same route you took up
the hill.
Crossing a Stream
Before driving through water, stop,
get out if necessary, and make sure
that:
●The water is not deep enough to
cover your wheel hubs, axles, or
exhaust pipe. You could stall and
not be able to restart your engine.
The water can also damage
important vehicle components.

●The banks are sloped so you can
drive out.●The water is not flowing too fast.
Deep rushing water can sweep you
downstream. Even very shallow
rushing water can wash the
ground from under your tires and
cause you to lose traction and
possibly roll over.●The banks and surface under the
water provide good traction. The
water may hide hazards such as
rocks, holes, or mud.
If you decide it is safe to drive
through water, choose a suitable
speed, and proceed without shifting,
changing speeds, stopping, or
shutting off the engine.
After driving through water, test your
brakes. If they got wet, gently
‘‘ pump ’’them while driving slowly
until they operate normally. If the water is deeper than the wheel
hubs, some additional service may be
required. This service is not covered
by your warranties.
If You Get Stuck
If you get stuck, carefully try to go in
the direction (forward or reverse)
that you think will get you unstuck.
Do not spin the tires at high speeds.
It will not help you get out and may
cause damage to the transmission or
SH-AWD system.
If you are still unable to free yourself,
your vehicle is equipped with front
and rear tow hooks designed for this
purpose.
Use a nylon strap to attach the MDX
to the recovery vehicle and carefully
take out the slack in the strap. Once
the strap is tight, the recovery
vehicle should apply force.
Remember that the recovery vehicle
needs good traction to avoid
becoming stuck, too.You should never use a jack to try to
get unstuck. Your vehicle could
easily slip off the jack and hurt you or
someone else.
Towing a Trailer Off-Road
You may be able to safely tow a
lightweight trailer (such as a
motorcycle or small tent trailer) off-
road if you follow these guidelines:
●Do not exceed 1,000 lbs (450 kg)
or a tongue weight of 100 lbs (45
kg).●Stay on smooth, level dirt roads,
and avoid driving in hilly terrain.●Allow extra room for starting,
stopping, and turning.●Slow down if you encounter bumps
or other obstacles.
