2012 Acura MDX wheel

The super handling-all wheel drive
(SH-AWD) system is a full time all-
wheel-drive system that
automatically controls and transfers
varying amounts of engine torque to
all wheels independently, according
to the driving conditions.
While the SH-AWD system helps to
enhance the vehicle's driving
stability in all situations, it is still
your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.SH-AWD Torque Distribution
Monitor
The SH-AWD torque distribution
monitor on the multi-information
display shows you the amount of
torque being sent to the wheels.
Each wheel-right front (RF), left front
(LF), right rear (RR), and left rear
(LR)-has its own torque indicator.Each torque indicator is displayed as
a bar graph divided into 5 segments.
The number of segments represents
the amount of torque distributed to
each wheel.
When there is only a slight change in
torque distribution while driving,
such as cruising on level roads at the
same speed, the torque distribution
monitor may stop displaying the
amount of torque. This is not a
system problem. The monitor will
show the amount if the system
senses any change in torque
distribution.

If the SH-AWD indicator blinks while
driving, it indicates the differential
temperature is too high. You will also
see an‘‘SH-AWD DIFF TEMP.
HIGH’’message on the multi-
information display. If this happens,
pull to the side of the road when it is
safe, shift to Park, and let the engine
idle until the indicator goes out. If
the indicator does not go out, take
your vehicle to a dealer to have it
checked.
If the SH-AWD indicator on the
instrument panel stays on, and the
‘‘CHECK SH-AWD SYSTEM’’
message also appears on the multi-
information display, there is problem
with the SH-AWD system.Your vehicle still has normal front-
wheel drive with vehicle stability
assist (VSA), but does not have the
advantages of SH-AWD. Have your
vehicle checked by a dealer as soon
as possible.

Driving

Always use the parking brake when
you park your vehicle. Make sure the
parking brake is set firmly, or your
vehicle may roll if it is parked on an
incline.
Set the parking brake before you put
the transmission in Park. This keeps
the vehicle from moving and putting
pressure on the parking mechanism
in the transmission.Parking Tips
●
Make sure the moonroof and the
windows are closed.
●
Turn off the lights.
●
Place any packages, valuables, etc.
in the cargo area or take them with
you.
●
Lock the doors and the tailgate.
●
Never park over dry leaves, tall
grass, or other flammable
materials. The hot three way
catalytic converter could cause
these materials to catch on fire.
●
If the vehicle is facing uphill, turn
the front wheels away from the
curb.
●
If the vehicle is facing downhill,
turn the front wheels toward the
curb.
●
Check the indicator on the
instrument panel to verify that the
security system is set.
●
Make sure the parking brake is
fully released before driving away.
Driving with the parking brake
partially set can overheat or
damage the rear brakes.

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 button
(see page 474). If this happens, you
cannot turn the VSA system off by
pressing the VSA OFF button 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 page 551).
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. 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.

Braking System
Your vehicle is equipped with disc
brakes at all four wheels. A power
assist helps reduce the effort needed
on the brake pedal. The emergency
brake assist system increases the
stopping force when you depress the
brake pedal hard in an emergency
situation. The anti-lock brake system
(ABS) helps you retain steering
control when braking very hard.
Resting your foot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their effectiveness
and reduces brake pad life. In
addition, fuel economy can be
reduced. It also keeps your brake
lights on all the time, confusing
drivers behind you.Constant application of the brakes
when going down a long hill builds
up heat and reduces their
effectiveness. Use the engine to
assist the brakes by taking your foot
off the accelerator and downshifting
to a lower gear.
Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they feel
normal. If not, apply them gently and
frequently until they do. Be extra
cautious in your driving.
Tire Pressure Monitoring System (TPMS), Braking System460

Braking System Design
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the left-front brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
Brake Wear Indicators
All four brakes have audible brake
wear indicators.
If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal for
the brakes to occasionally squeal or
squeak when you apply them.Anti-lock Brakes (ABS)
The anti-lock brake system (ABS)
helps prevent the wheels from
locking up, and helps you retain
steering control by pumping the
brakes rapidly, much faster than a
person can do it.
The electronic brake distribution
(EBD) system, which is part of the
ABS, also balances the front-to-rear
braking distribution according to
vehicle loading.
You should never pump the brake pedal.Let the ABS work for you by always
keeping firm, steady pressure on the
brake pedal. This is sometimes
referred to as‘‘stomp and steer.’’You will feel a pulsation in the brake
pedal when the ABS activates, and
may hear some noise. This is normal:
it is the ABS rapidly pumping the
brakes. On dry pavement, you will
need to press on the brake pedal
very hard before the ABS activates.
However, you may feel the ABS
activate immediately if you are trying
to stop on snow or ice.

Driving

ABS Indicator
If this indicator comes on, the anti-
lock function of the braking system
has shut down. The brakes still work
like a conventional system, but
without anti-lock. You should have
your dealer inspect your vehicle as
soon as possible.
You will also see a‘‘CHECK ABS
SYSTEM’’message on the multi-
information display (see page 88).
If the indicator comes on while
driving, test the brakes as instructed
on page 564.If the ABS indicator and the brake
system indicator come on together,
and the parking brake is fully
released, the EBD system may also
be shut down.
Test your brakes as instructed on
page 564. If the brakes feel normal,
drive slowly and have your vehicle
repaired by your dealer as soon as
possible. Avoid sudden hard braking
which could cause the rear wheels to
lock up and possibly lead to a loss of
control.Important Safety Reminders
ABS does not reduce the time or
distance it takes to stop the
vehicle.It only helps with steering
control during braking.
ABS will not prevent a skid that
results from changing direction
abruptly,such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather
conditions.
ABS cannot prevent a loss of
stability.Always steer moderately
when you are braking hard. Severe
or sharp steering wheel movement
can still cause your vehicle to veer
into oncoming traffic or off the road.
A vehicle with ABS may require a
longer distance to stopon loose or
uneven surfaces, such as gravel or
snow, than a vehicle without anti-
lock.
Anti-lock Brakes (ABS)462

Because of the road condition
(curved, winding, etc.) or the state of
your vehicle (turning angle, lane
position, etc.), CMBS can sometimes
mistake a stationary object (light
pole, traffic sign, guard rail, etc.) as a
vehicle ahead of you and temporarily
operate. This is normal.Important Safety Reminder
The main purpose of the CMBS is to
reduce the severity of injuries caused
by an unavoidable collision. While
the CMBS may help to alert you and
minimize the severity of a collision, it
may not activate in every dangerous
situation.
Even with the CMBS, it is still your
responsibility to operate the brake
pedal and steering wheel
appropriately, according to the
driving conditions.
