Driving Guidelines
Your vehicle has higher ground
clearance that allows you to travel
over bumps, obstacles, and rough
terrain. It also provides good
visibility so you can anticipate
problems earlier.
Because your vehicle rides higher off
the ground, it has a high center of
gravity that can cause it to roll over if
you make abrupt turns. Utility
vehicles have a significantly higher
roll over rate than other types of
vehicles.
To prevent rollovers or loss of
control:●Take corners at slower speeds
than you would with a passenger
vehicle.●Avoid sharp turns and abrupt
maneuvers whenever possible.
●Do not modify your vehicle in any
way that would raise the center of
gravity.●Do not carry heavy cargo on the
roof.Seepage 378for off-highway driving
guidelines.
Preparing to Drive
You should do the following checks
and adjustments before you drive
your vehicle.
1. Make sure all windows, mirrors, and outside lights are clean and
unobstructed. Remove frost, snow,
or ice.
2. Check that the hood is fully closed.
3. Visually check the tires. If a tire looks low, use a gauge to check its
pressure.
4. Check that any items you may be carrying are stored properly or
fastened down securely.
5. Check the seat adjustment (see page 140).

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.

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

Sequential SportShift ModeWith the shift lever in‘‘D ’’position,
you can select the Sequential
SportShift mode to shift gears much
like a manual transmission, but
without a clutch pedal.
When you move the shift lever from
‘‘ D ’’to ‘‘M’’ position, the display
shows the selected gear.
To enter the Sequential SportShift
mode, move the shift lever further to
the driver's side. To return to ‘‘D, ’’
move the shift lever to the
passenger's side.
In Sequential SportShift mode, each
time you push forward on the shift
lever, the transmission shifts to a
higher gear. Pull back on the lever to
downshift. The number of the gear
selected is displayed on the
instrument panel. When you accelerate away from a
stop, the transmission starts in first
gear. You have to manually upshift
between first and fifth gears. Make
sure you upshift before the engine
speed reaches the tachometer's red
zone.
The transmission remains in the
selected gear (5, 4, 3, 2, or 1). There
is no automatic downshift when you
push the accelerator pedal to the
floor.

The transmission may automatically
downshift from the higher gear to
the lower gear under these
conditions:
Driving on level roads and downhillTo shift from Speed range
4→ 3 under 19 mph
(31 km/h)
5 → 4 under 38 mph
(60 km/h)
Driving uphill To shift from Speed range
4→ 3 under 34 mph
(55 km/h)
5 → 4 under 47 mph
(75 km/h) Downshifting gives you more power
when climbing, and provides engine
braking when going down a steep
hill.
The transmission also shifts
automatically as the vehicle comes to
a complete stop. It downshifts to first
gear when the vehicle speed is under
10 mph (16 km/h).
If you try to manually downshift at a
speed that would cause the engine to
exceed the redline in a lower gear,
the transmission does not downshift.
The gear indicator will flash the
number of the lower gear several
times, then return to the higher gear.
If the vehicle speed slows to below
the redline of the selected lower gear
position while the indicator is
flashing, the transmission
downshifts, and the display shows
the selected lower gear.Automatic Transmission34408/06/06 16:58:07 09 ACURA MDX MMC North America Owner's M 50 31STX620 enu

Starting in Second GearWhen you are in Sequential
SportShift mode, and the vehicle is
stopped, push forward on the shift
lever to shift to second gear. You will
see‘‘2’’ in the display. Starting out in
second gear will help to reduce
wheelspin in deep snow or on a
slippery surface.
If you start out in second gear, the
transmission will be fixed in that
gear.
The transmission will not
automatically downshift to first gear
even when the vehicle speed is
under 10 mph (16 km/h). You need
to shift down to first gear manually.

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.
