2009 Acura MDX ignition

On models with navigation systemWhenever you shift to reverse (R)
with the ignition switch in the ON
(II) position, the rearview is shown
on the navigation system screen.
For the best picture, always keep the
rearview camera clean, and do not
cover the camera lens. To avoid
scratching the lens when you clean
it, use a moist, soft cloth.Since the rearview camera display
area is limited, you should always
back up slowly and carefully, and
look behind you for obstacles.

6. Check the adjustment of the insideand outside mirrors (see page
154).
7. Check the steering wheel adjustment (see page 124).
8. Make sure the doors and tailgate are securely closed and locked.
9. Fasten your seat belt. Check that your passengers have fastened
their seat belts (see page 15).
10. When you start the engine, check the gauges and indicators in the
instrument panel, and the
messages on the multi-information
display (see pages 63,72and 81). Starting the Engine
Your vehicle's starting system has an
auto control mode. When you turn
the ignition switch to the START (III)
position, this feature keeps the
engine's starter motor running until
the engine starts. Follow these
instructions to start the engine:
1. Apply the parking brake.
2. In cold weather, turn off all
electrical accessories to reduce the
drain on the battery.
3. Make sure the shift lever is in Park. Press on the brake pedal.
4. Without touching the accelerator pedal, turn the ignition switch to
the START (III) position, then
release the ignition switch. You do
not need to hold the ignition
switch in the START (III) position
to start the engine. Depending on
the outside temperature, the
starter motor runs for about 6 to 9
seconds until the engine starts. If you hold the ignition switch in
the START (III) position for more
than 7 seconds, the starter motor,
depending on the outside
temperature, runs for about 10 to
25 seconds until the engine starts.
If the engine does not start, wait at
least 10 seconds before trying
again.
The immobilizer system protects your
vehicle from theft. If an improperly-
coded key (or other device) is used, the
engine's fuel system is disabled. For
more information, see page
128.

5. If the engine does not start within15 seconds, or starts but stalls
right away, repeat step 4 with the
accelerator pedal pressed halfway
down. If the engine starts, release
pressure on the accelerator pedal
so the engine does not race.
6. If the engine fails to start, press the accelerator pedal all the way
down, and hold it there while
starting to clear flooding. If the
engine still does not start, return to
step 5.The engine is harder to start in cold
weather. Also, the thinner air found at
altitudes above 8,000 feet (2,400
meters) adds to this problem. Check Starting System Message
If there is a problem with the starting
system, you will see a
‘‘CHECK
STARTING SYSTEM ’’message on
the multi-information display when
the ignition switch is turned to the
ON (II) position. You will also see
this message when the auto control
mode of the starting system has a
problem. If this message is on, the ignition
switch has to be held in the START
(III) position manually until the
engine starts. The ignition switch can
be held in that position up to 15
seconds.
Even though you may be able to start
the engine manually without the auto
control mode of the starting system,
have your dealer inspect your
vehicle.

Shift Lever Position IndicatorsThese indicators on the instrument
panel show which position the shift
lever is in. In the Sequential
SportShift Mode, the‘‘M’’ indicator
next to the ‘‘D ’’indicator comes on,
and the illuminated number under
the charging system indicator shows
you the gear you have selected. The
‘‘D ’’indicator comes on for a few
seconds when you turn the ignition
switch to the ON (II) position. If it
flashes while driving (in any shift
position), it indicates a possible
problem in the transmission.
If the malfunction indicator lamp
comes on along with the ‘‘D ’’
indicator, there is a problem with the
automatic transmission control
system. Avoid rapid acceleration, and
have the transmission checked by
your dealer as soon as possible.
When the ‘‘D ’’indicator warns of a
possible problem with the
transmission, you will see a ‘‘CHECK
TRANSMISSION ’’message on the
multi-information display (see page
82). Shifting
To shift from Park to any position,
press firmly on the brake pedal, and
press the release button on the front
of the shift lever, then move the
lever. You cannot shift out of Park
when the ignition switch is in the
LOCK (0) or ACCESSORY (I)
position.

－This position
mechanically locks the transmission.
Use Park whenever you are turning
off or starting the engine. To shift out
of Park, you must press on the brake
pedal and press the release button on
the shift lever. Make sure your foot is
off the accelerator pedal.
If you have done all of the above and
still cannot move the lever out of
Park, see Shift Lock Release on
page346. To avoid transmission damage, come
to a complete stop before shifting
into Park. The shift lever must be in
Park before you can remove the key
from the ignition switch.
Reverse (R)
－Press the brake
pedal and press the release button on
the front of the shift lever to shift
from Park to reverse. To shift from
reverse to neutral, come to a
complete stop, and then shift. Press
the release button before shifting
into reverse from neutral.
Neutral (N) －Use neutral if you
need to restart a stalled engine, or if
it is necessary to stop briefly with the
engine idling. Shift to the Park
position if you need to leave your
vehicle for any reason. Press on the
brake pedal when you are moving
the shift lever from neutral to
another gear. Drive (D)
－Use this position for
your normal driving. The
transmission automatically selects a
suitable gear (1 through 5) for your
speed and acceleration. You may
notice the transmission shifting up at
higher engine speeds when the
engine is cold. This helps the engine
warm up faster.Automatic Transmission34208/06/06 16:58:07 09 ACURA MDX MMC North America Owner's M 50 31STX620 enu

Drive (D
3)－ This position is similar
to D, except only the first three gears
are selected. Use D
3when towing a
trailer in hilly terrain, or to provide
engine braking when going down a
steep hill. D
3can also keep the
transmission from cycling between
third, fourth, and fifth gears in stop-
and-go driving.
For faster acceleration when in D
3or
D, you can get the transmission to
automatically downshift by pushing
the accelerator pedal to the floor.
The transmission will shift down one,
two, or three gears, depending on
your speed. Engine Speed Limiter
If you exceed the maximum speed
for the gear you are in, the engine
speed will enter into the
tachometer's red zone. If this occurs,
you may feel the engine cut in and
out. This is caused by a limiter in the
engine's computer controls. The
engine will run normally when you
reduce the rpm below the red zone.
Before downshifting, make sure the
engine will not go into the
tachometer's red zone.
Shift Lock Release
This allows you to move the shift
lever out of Park if the normal
method of pushing on the brake
pedal and pressing the release button
does not work.
1. Set the parking brake.
2. Remove the key from the ignition
switch.

For example, if you check and fill
your tires in a warm area, then drive
in extremely cold weather, the tire
pressure will be lower than
measured and could be underinflated
and cause the low tire pressure/
TPMS indicator to come on. Or, if
you check and adjust your tire
pressure in cooler conditions, and
drive into extremely hot conditions,
the tire may become overinflated.
However, the low tire pressure/
TPMS indicator will not come on if
the tires are overinflated.
Refer to page415for tire inflation
guidelines.
If there is a problem with the TPMS,
this indicator begins to flash. It stops
flashing after approximately 1
minute, then stays on. You will also
see a‘‘CHECK TPMS SYSTEM’’
message on the multi-information
display (see page 82). Although your tire pressure is
monitored, you must manually check
the tire pressures monthly.
Each tire, including the spare, should
be checked monthly when the
vehicle is cold, and set to the
recommended inflation pressure as
specified on the vehicle placard and
in the owner's manual (see page
416).
Tire Pressure Monitor
To select the tire pressure monitor,
press the INFO button several times
with the ignition switch in the ON
(II) position.
You will see the above display on the
multi-information display when all
tire pressures are normal.

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 surfaces. 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. There may also
be some noise from the VSA
hydraulic system. 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.
VSA Activation Indicator
When VSA activates, you will see the
VSA activation indicator blink.Vehicle Stability Assist
(VSA) System Indicator
If this indicator comes on while
driving, pull to the side of the road
when it is safe, and turn off 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.
NOTE: The main function of the VSA
system is generally known as
Electronic Stability Control (ESC).
The system also includes a traction
control function. 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 vehicle as
soon as possible.
