Low Tire Pressure/
TPMS Indicator
This indicator normally comes on for
a few seconds when you turn the
ignition switch to the ON (II)
position.
This indicator has two functions:
1. If it comes on while driving, it indicates that one or more of your
vehicle's tires are significantly low
on pressure.
You will also see a ‘‘CHECK TIRE
PRESSURE ’’message on the multi-
information display (see page82).
Check the tire pressure monitor on
the multi-information display and
determine the cause (see page352). If this happens, pull to the side of the
road when it is safe, check which tire
has lost pressure on the multi-
information display, and determine
the cause. If it is because of a flat tire,
have the flat tire repaired as soon as
possible. If two or more tires are
underinflated, call a professional
towing service. For more
information, see page446.
2. If this indicator begins to flash,
there is a problem with the tire
pressure monitoring system
(TPMS). You will also see a
‘‘CHECK TPMS SYSTEM’’
message on the multi-information
display. The indicator continues to
flash for a while (approximately 1
minute), then stays on. If this
happens, have your dealer check
the system as soon as possible.
For more information, see page
354.
A/T Temperature
Indicator
This indicator monitors the
temperature of the automatic
transmission fluid. It should come on
for a few seconds when you turn the
ignition switch to the ON (II)
position. If it comes on while driving,
it means the transmission fluid
temperature is too high. Pull to the
side of the road when it is safe, shift
to Park, and let the engine idle until
the indicator goes out.
You will also see an ‘‘A/T TEMP
HIGH ’’message on the multi-
information display (see page82).
Continuing to drive with the A/T
temperature indicator on may cause
serious damage to the transmission.

3. When you turn the wiper switch tothe ‘‘OFF ’’position, the wiper will
return to its parked position.
4. Rotate the switch counterclockwise to spray the
window washer.
When you shift the transmission to
the reverse position with the front
windshield wipers activated, the
rear window wiper operates
automatically.
When the wiper control lever
position is INT, the rear wiper
operates intermittently. When it is
LO or HI, the rear wiper operates
continuously.
The rear window washer uses the
same fluid reservoir as the
windshield washer. Turn Signal and Headlights

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

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
