µ 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.
Press the brake
pedal and press the release button
on the front of the shift lever to shift
fr om Park to reverse. To shift from
reverse to neutral, come to a
completestop,andthenshift.Press
the release button before shifting
into reverse from neutral.
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. Use
this position for
your norm al driving. The
transmission automatically selects a
suitable gear (1 through 5) for your
sp eed 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.
This position mechani-
cally 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 shif t lever. Make sure your
f oot is of f the accelerator pedal.
If you have done all of the above and
still cannot move the lever out of
Park, see on
page . 338

With the shif t lever in ‘‘D’’ position,
you can select the Sequential
SportShift mode to shift gears much
like a manual transmission, but
without a clutch pedal.
To enter the Sequential SportShif t
mode, move the shif t lever f urther to
the driver’s side. To return to ‘‘D,’’
move the shift lever to the
passenger’s side.
In Sequential SportShif t mode, each
time you push f orward on the shif t
lever, the transmission shifts to a
higher gear. Pull back on the lever to
downshif t. The number of the gear
selected is displayed on the
instrument panel.
When you move the shif t lever f rom
‘‘D’’ to ‘‘M’’ position, the display
shows the selected gear. The transmission remains in the
selectedgear(5,4,3,2,or1).There
is no automatic downshif t when you
push the accelerator pedal to the
f loor. When you accelerate away f rom a
stop, the transmission starts in f irst
gear. You have to manually upshift
between f irst and f if th gears. Make
sure you upshif t bef ore the engine
speed reaches the tachometer’s red
zone.

µIf you exceed the maximum speed
f or the gear you are in, the engine
speed will enter into the tachometer’s
red zone. If this occurs, you may f eel
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.
Bef ore downshif ting, make sure the
engine will not go into the
tachometer’s red zone.
This position is
similar to D, except only the f irst
three gears are selected. Use D
when towing a trailer in hilly terrain,
or to provide engine braking when
going down a steep hill. D can also
keep the transmission f rom cycling
between third, f ourth, and f if th gears
in stop-and-go driving.
ForfasteraccelerationwheninD or
D, you can get the transmission to
automatically downshif t by pushing
the accelerator pedal to the floor.
The transmission will shif t down one,
two, or three gears, depending on
your speed. This allows you to move the shif t
lever out of Park if the normal
method of pushing on the brake
pedal and pressing the release
button does not work.
Remove the key from the ignition
switch. Set the parking brake.

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

If the autom atic transmission fluid
temperature increases and exceeds
the speci fied limit, the A/T
temperature indicator comes on (see
page ). You will also see a ‘‘A/T
TEMP HIGH’’ message on the multi-
information display.
Make turnsmoreslowlyandwider
than normal. The trailer tracks a
smaller arc than your vehicle, and it
canhitorrunoversomethingthe
vehicle misses.
Allow more time and distance for
braking. Do not brake or turn
suddenly as this could cause the
trailer to jackknife or turn over.
When
driving uphill and downhill,
use the Sequential SportShift mode
to provide the proper engine power
and engine braking on each gear.
Select fourth, third, second, or first
gear; dep ending on the vehicle
speeds and road condition. Do not
use fifth gear. The recommended
speed range for each gear position is
showninthetable.

Use D position when towing a trailer
on level roads. D is the proper shif t
lever position to use when towing a
trailer in hilly terrain. (See ‘‘ ’’onthenextpagefor
additional gear information.)
When towing a f ixed-sided trailer (e.
g., camper), do not exceed 55 mph
(88 km/h). At higher speeds, the
trailer may sway or affect vehicle
handling. 68

When climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, turn the air
conditioning off, reduce speed and, if
necessary, pull to the side of the
ro ad to let the engine cool.
If the transmission shifts frequently
while going up a hill, shift to D3.
If you must stop when facing uphill,
use the foot brake or parking brake.
Do not try to hold the vehicle in
placebypressingontheaccelerator,
as this can cause the automatic
transmission to overheat.
When driving down hills, reduce
your speed and shift down to D . Do
not ‘‘ride’’ the brakes. Al
ways drive slowly and have
someone guide you when backing up.
Grip the of the steering wheel,
then turn the wheel to the left to get
the trailer to move to the left. Turn
the wheel to the right to move the
trailer to the right.
Follow all norm al precau tions when
parking, including putting the
transmission in Park and firmly
setting the parking brake. Also, place
wheel chocks at each of the trailer’s
tires. If
the vehicles tires slip when
retr ieving a boat from the water,
keep D position and do not use the
sequential sport shif t mode. This
prevents the transmission damage.
Your vehicle is not designed to be
towed behind a motor home. If your
vehicle needs to be towed in an
emergency, see page .
Crosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause the trailer to
sway. When being passed by a large
vehicle, keep a constant speed, and
steer straight ahead. Do not try to
make quick steering or braking
corrections.

The banks are sloped so you can
drive out.
The water is not f lowing too f ast.
Deep rushing water can sweep you
downstream. Even very shallow
rushingwatercanwashthe
ground f rom under your tires and
cause you to lose traction and
possibly roll over.
The banks and surf ace under the
water provide good traction. The
water may hide hazards such as
rocks, holes, or mud.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 decide it is saf e to drive
through water, choose a suitable
speed, and proceed without shif ting,
changing speeds, stopping, or
shutting of f the engine. If you get stuck, caref ully try to go in
the direction (f orward or reverse)
that you think will get you unstuck.
Donotspinthetiresathighspeeds.
It will not help you get out and may
cause damage to the transmission or
SH-AWD system.
After driving through water, test
your brakes. If they got wet, gently
‘‘pump’’ them while driving slowly
until they operate normally. If you are still unable to f ree yourself ,
your vehicle is equipped with f ront
and rear tow hooks designed f or this
purpose.
Use a nylon strap to attach the MDX
to the recovery vehicle and caref ully
take out the slack in the strap. Once
the strap is tight, the recovery
vehicle should apply f orce.
Remember that the recovery vehicle
needs good traction to avoidbecoming stuck, too.
You should never use a jack to try to
get unstuck. Your vehicle could
easily slip of f the jack and hurt you
or someone else.
You may be able to safely tow a
lightweight trailer (such as a
motorcycle or small tent trailer) of f -
road if you f ollow 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 f or starting,
stopping, and turning.
Slow down if you encounter bumps
or other obstacles.
