steering Acura MDX 2003 Owner's Manua

Discuss any additional needs with
your trailer sales or rental agency,
and make sure all equipment is
properly installed and maintained.
Since local requirements may vary,
check with appropriate state
authorities to be sure that your
equipment will meet all regulations
in the areas where you plan to tow. Towing generally requires a variety
of supplemental equipment. To
ensure the best quality, we
recommend that you purchase Acura
equipment whenever possible. Your
dealer offers a trailer package that
includes a hitch, a ball mount, a
wiring harness, a transmission f luid
cooler and a heavy-duty power
steering f luid cooler.We strongly recommend that you
have your Acura dealer install a
genuine Acura hitch and the
required f luid coolers. Using non-
Acura equipment may result in
serious damage to your vehicle.
A weight distributing hitch is not
recommended f or use with your
MDX as an improperly adjusted
weight distributing hitch may reduce
handling stability and braking
perf ormance.
Always use saf ety chains when you
tow a trailer. Make sure the chains
are secured to the trailer and hitch,
and that they cross under the tongue
so they can catch the trailer if it
becomes unhitched. Leave enough
slack to allow the trailer to turn
corners easily, but to do not let the
chains drag on the ground.This device is recommended if your
trailer tends to sway. Your trailer
maker can tell you what kind of sway
control you need and how to install it.
To help prevent overheating, a
heavy-duty transmission f luid cooler
and a heavy-duty power steering
f luid cooler are required f or trailer
towing. These coolers are available
only f rom your Acura dealer.

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 down one
gear.
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,
as this can cause the automatic
transmission to overheat.
When driving down hills, reduce
your speed and shif t down to D . Do
not ‘‘ride’’ the brakes, and remember
it will take longer to slow down and
stop when towing a trailer.Crosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause your trailer
to sway. When being passed by a
truck or other 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 of the steering
wheel; then turn the wheel to the lef t

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).
Otherwise, 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 and installer. Follow
the manufacturer’s attachment
instructions caref ully.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.)
Do the f ollowing to prepare your
MDX f or ‘‘f lat towing.’’ Perf orm this
procedure every day immediately
bef ore you begin towing, and f ollow
this procedure exactly; otherwise,
severe automatic transmission
damage will occur. Check the transmission f luid level
(see page ). Maintaining the correct f luid level
is very important.
Start the engine.
Leave the ignition switch in
ACCESSORY (I) 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. Release the parking brake. ShifttoD ,thentoN.Letthe

Towing Your Vehicle Behind a Motorhome
Driving284
The steering system can be damaged if
the steering wheel is locked. Leave the
ignition switch in Accessory (I), and
make sure the steering wheel turns
f reely bef ore you begin towing.
Improper towing preparation will
damage the transmission. Follow the
above procedure exactly. If you cannot
shif t the transmission or start the
engine, your vehicle must be
transported on a f lat-bed or trailer.

Test your brakes from time to time
to make sure they are operating
properly. This will also give you a
f eel f or how much traction you have
on a given surf ace.
Off-highway, the basic turning
technique is to drive at low speed
and gradually adjust the amount of
steering to suit the surf ace.
You should have no problem making
sharp turns at low speed on level
ground. But never make an abrupt
turn at higher speeds, on or of f
pavement. With a higher center of
gravity, your vehicle can more easily
tip or roll over.Bef ore driving up or down a hill, stop
and assess the situation. If you can’t
clearly see all road conditions (good
traction, no bumps, holes or other
obstacles, a safe way out, etc.) walk
the slope bef ore you drive on it. If
you have any doubt about whether
you can saf ely drive on the slope,
. Find another route.
If you are driving up a hill and f ind
that you cannot continue (because of
the steepness, a large obstacle, etc.), . Your vehicle
could roll over. Slowly back down the
hill, f ollowing the same route you
took up the hill. Bumps, holes, rocks, and other
obstacles can be hazardous. Debris
in the road can damage your
suspension or other components.
Even small rocks can cut your tires.
More important, because your
vehicle has a high center of gravity,
driving over a large obstacle, or
allowing a wheel to drop into a deep
hole, can cause your vehicle to tip or
roll over.
Drive slow enough to observe
obstacles ahead and maneuver
around them. If you can’t avoid a
serious obstacle, turn around and
look f or a better route.
