This position mechani-
cally locks the transmission. Use
Park whenever you are turning of f or
starting the engine. To shif t out of
Park, you must press on the brake
pedal and have your f oot 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 .
To avoid transmission damage, come
to a complete stop bef ore shif ting
into Park. The shif t lever must be in
Park bef ore you can remove the key
from the ignition switch. Press the brake
pedal, making sure to keep your f oot
of f the accelerator pedal, then shif t
f rom Park to Reverse. To shif t f rom
Neutral to Reverse, come to a
completestopandthenshift. Use Neutral if you
need to restart a stalled engine, or if
it is necessary to stop brief ly with
the engine idling. Shif t to the Park
position if you need to leave your
vehicle for any reason. Press the
brake pedal, making sure to keep
your f oot of f the accelerator pedal,
when you are moving the shif t lever
f rom Neutral to another gear.
Your vehicle has a reverse lockout so
you cannot accidentally shif t to
Reverse from Neutral or any other
driving position when the vehicle
speed exceeds 7 9 mph (12 14
km/h).
If you cannot shif t to Reverse when
the vehicle is stopped, press the
brake pedal and slowly shift to
Neutral, and then to Reverse.
If there is a problem in the reverse
lockout system, or your vehicle’s
battery is disconnected or goes dead,
you cannot shif t to Reverse. (Ref er
to
on page ). Use this position f or
normal driving. The transmission
automatically selects a suitable gear
f or your speed and acceleration. You
may notice the transmission shif ting
up at higher speeds when the engine
is cold. This helps the engine warm
up f aster.

µµ µThese positions
are similar to D , except when you
select the D position, only the f irst
f our gears are selected. When you
select D , only the f irst three gears
are selected. D can also keep the
transmission f rom cycling between
f ourth and f if th gears in stop-and-go
driving, and D can keep the
transmission f rom cycling between
third and f ourth gears. This position locks
thetransmissioninsecondgear.It
does not downshif t to f irst gear
when you come to a stop.
Use Second gear: For more power when climbing.
To increase engine braking when
going down steep hills.
For starting out on a slippery
surf ace or in deep snow. With the lever in this
position, the transmission locks in
First gear.
If you shif t into First position when
the vehicle speed is above 31 mph
(50 km/h), the transmission shif ts
into Second gear f irst to avoid
sudden engine braking.
If 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.
Use D to provide engine braking
when going down a steep hill. D
gives you more power and increased
engine braking.
When driving downhill with a
trailer. To help reduce wheel spin.

The Variable Torque Management
4WD System (VTM-4) automatically
transf ers varying amounts of engine
torque to the rear wheels under
lower traction conditions.The vehicle must be stopped with
the engine running.
If more traction is needed when your
vehicle is stuck, or is likely to
become stuck, you can use the
VTM-4 Lock button to increase
torque to the rear wheels. Move the shift lever to First (1),
Second (2), or Reverse (R) gear.
Press the VTM-4 Lock button.
The indicator in the button comes
on.
To get unstuck, apply light pressure
to the accelerator pedal. Do not spin
the f ront tires f or more than a f ew
seconds. Because of the amount of
torque applied to the rear tires, they
should not spin. This is normal. If
you are not able to move the vehicle,
stop and reverse direction. do
one of the f ollowing: Press the VTM-4 Lock button.
Move the shift lever to D , D or
D.
Turn the ignition switch to LOCK
(0).
The VTM-4 Lock will temporarily
disengage when the vehicle speed
exceeds 18 mph (30 km/h). It will
automatically engage again as the
speed slows below 18 mph (30
km/h). The indicator in the button
will remain on.

Do not use the VTM-4 Lock button on
dry, paved roads. Driving on dry,
paved roads with VTM-4 Lock ON may
damage the rear dif f erential when
making a turn. Strange noise and
vibration can also result. Do not continuously spin the f ront tires
of your vehicle. Continuously spinning
the f ront tires can cause transmission
or rear dif f erential damage.

When climbing hills, closely watch
your temperature gauge. If it nears
the red (hot) mark, turn the air
conditioning of f , reduce speed and, if
necessary, pull to the side of the
road to let the engine cool.
If the transmission shif ts f requently
while going up a hill, shif t to D3.
If you must stop when f acing uphill,
use the f oot brake or parking brake.
Do not try to hold the vehicle in
placebypressingontheaccelerator,
this could cause the automatic
transmission to overheat.
When driving down hills, reduce
your speed and shif t down to D . Do
not ‘‘ride’’ the brakes.Crosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause trailer
swaying. 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.
Always drive slowly and have
someone guide you when backing up.
Grip the bottom of the steering
wheel, then turn the wheel to the lef t
to get the trailer to move to the lef t.
Turn the wheel to the right to move
the trailer to the right.
Follow all normal precautions when
parking, including putting the
transmission in Park and f irmly
setting the parking brake. Also, place
wheel chocks at each of the trailer’s
tires.If the vehicle’s tires slip when
retrieving a boat f rom the water,
shif t to f irst gear, and turn on VTM-4
Lock (see page ). Disengage
VTM-4 Lock as soon as the boat is
out of the water to prevent damage
to the VTM-4 system.

Your MDX can be towed behind a
motorhome at legal highway speeds
up to 65 mph (100 km/h). Do not
exceed 65 mph (100 km/h) or severe
transmission damage will occur. To
avoid damage to the 4WD system, it
must be towed with all f our wheels
on the ground (f lat towing).
When purchasing a tow bar, make
sure you select a reputable
manuf acturer. Follow the
manufacturer’s attachment
instructions caref ully.
Perf orm this procedure every day
immediately bef ore you begin towing.
Otherwise, severe automatic
transmission damage will occur.Start the engine. Check the transmission f luid level
(see page ). Press on the brake pedal. Shif t the
lever through all the positions (P,
R,N,D,D,D,2,1).
ShifttoD ,thentoN.Letthe

Release the parking brake.
Leave the ignition switch in the
ACCESSORY (I) position so the
steering wheel does not lock.
Make sure the radio and any items
plugged into the accessory power
sockets are turned of f so you do
not run down the battery.
If you tow more than 8 hours in one
day, you should repeat the above
procedure at least every 8 hours
(when you stop f or f uel, etc.)
