2012 Acura MDX stop start

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 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.
Low Tire Pressure/
TPMS Indicator
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is significantly underinflated.
You should stop and check your tires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle's tire information
placard.
It is possible that the pressures
shown on the multi-information
display and the pressures you
manually measure are slightly
different.
If the difference is significant or you
cannot make the low tire pressure/
TPMS indicator and message on the
multi-information display go out after
inflating the tires to the specified
values, have your dealer check the
system as soon as possible.If you think you can safely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure.
If the tire is flat, or if the tire pressure
is too low to continue driving, replace
the tire with the compact spare tire
(see page 551).
Driving on a significantly under-
inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
Because tire pressure varies by
temperature and other conditions,
the low tire pressure/TPMS
indicator may come on unexpectedly.

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
page 545).
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.Hill Start Assist
Your vehicle is equipped with a hill
start assist feature to help prevent
the vehicle from rolling on steep
inclines as you move your foot from
the brake pedal to the accelerator.
This feature starts operating a few
seconds after you are in any drive
gear position (when faced uphill) or
in reverse (when faced downhill).
This feature requires that the vehicle
has come to a complete stop before it
can work.
Hill start assist may not hold a
heavily loaded vehicle, such as when
your vehicle is connected to a trailer,
or prevent your vehicle from rolling
downhill on a very steep or slippery
slope.
Vehicle Stability Assist (VSA
®), aka Electronic Stability Control (ESC), System

Driving

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.
Off-Highway Driving Guidelines502

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.

Driving

Snow Tires
If you mount snow tires on your
vehicle, make sure they are radial
tires of the same size and load range
as the original tires. Mount snow
tires on all four wheels. The traction
provided by snow tires on dry roads
may be lower than your original tires.
Check with the tire dealer for
maximum speed recommendations.
Tire Chains
Mount tire chains on your tires when
required by driving conditions or
local laws. Install them only on the
front tires.
Because your vehicle has limited tire
clearance, Acura strongly
recommends using the chains listed
below.
SCC Super Z-6＃SC 435When installing chains, follow the
manufacturer's instructions and
mount them as tightly as you can.
Drive slowly with chains installed. If
you hear them contacting the body
or chassis, stop and investigate.
Make sure the chains are installed
tightly, and that they are not
contacting the brake lines or
suspension. Remove the chains as
soon as you start driving on cleared
roads.
Using the wrong chains, or not
properly installing chains, can
damage the brake lines and
cause a crash in which you can
be seriously injured or killed.
Follow all instructions in this
owner's manual regarding the
selection and use of tire chains.
Traction devices that are the wrong size
or improperly installed can damage
your vehicle's brake lines, suspension,
body, and wheels. Stop driving if they
are hitting any part of the vehicle.
Wheels
Clean the wheels as you would the
rest of the exterior. Wash them with
the same solution, and rinse them
thoroughly.
Aluminum alloy wheels have a
protective clear-coat that keeps the
aluminum from corroding and
tarnishing. Cleaning the wheels with
harsh chemicals (including some
commercial wheel cleaners) or a stiff
brush can damage the clear-coat. To
clean the wheels, use a mild
detergent and a soft brush or sponge.

4. If the temperature gauge stays at
the red mark, turn off the engine.
5. Look for any obvious coolant
leaks, such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you
continue driving (seeEmergency
Towingon page 572).
6. If you do not find an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
7. If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the
temperature gauge, or lower,
before checking the radiator.
Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.
8. Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. After the
pressure releases, push down on
the cap, and turn it until it comes
off.9. Start the engine and set the
climate control to AUTO at‘‘Hi.’’
Add coolant to the radiator up to
the base of the filler neck. If you
do not have the proper coolant
mixture available, you can add
plain water. Remember to have the
cooling system drained and refilled
with the proper mixture as soon as
you can.
10. Put the radiator cap back on
tightly. Run the engine, and check
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (seeEmergency
Towingon page 572).
11. If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has gone
down, add coolant to the MAX
mark. Put the cap back on tightly.

Taking Care of the Unexpected

Low Oil Pressure Indicator
This indicator should never
come on when the engine is
running. If it starts flashing or stays
on, the oil pressure has dropped very
low or lost pressure. Serious engine
damage is possible, and you should
take immediate action.
You will also see a‘‘CHECK
ENGINE OIL LEVEL’’message on
the multi-information display when
this indicator comes on.
Running the engine with low oil
pressure can cause serious mechanical
damage almost immediately. Turn off
the engine as soon as you can safely get
the vehicle stopped.1. Safely pull off the road, and shut
off the engine. Turn on the hazard
warning indicators.
2. Let the vehicle sit for a minute.
Open the hood, and check the oil
level (see page 427). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
3. If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page 517).
4. Start the engine, and watch the oil
pressure indicator. If it does not go
out within 10 seconds, turn off the
engine. There is a mechanical
problem that needs to be repaired
before you can continue driving
(seeEmergency Towingon page
572).Charging System Indicator
If the charging system
indicator comes on brightly
when the engine is running, the
battery is not being charged.
You will also see a‘‘CHECK
CHARGING SYSTEM’’message on
the multi-information display (see
page 87).
Immediately turn off all electrical
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.
Go to a service station or garage
where you can get technical
assistance.
