steering Acura MDX 2004 Owner's Guide

The Anti-lock Brake System (ABS)
helps prevent the brakes f rom
locking up and helps you retain
steering control by pumping the
brakes rapidly, much f aster than a
person can do it.
The ABS also balances the f ront-to-
rear braking distribution according
to vehicle loading.
Let the ABS work f or you by always
keeping f irm, steady pressure on the
brake pedal. This is sometimes
ref erred to as ‘‘stomp and steer.’’You will f eel a pulsation in the brake
pedal when the ABS activates, and
may hear some noise. This is normal:
it is the ABS rapidly pumping the
brakes. On dry pavement, you will
need to press on the brake pedal
very hard before the ABS activates.
However, you may f eel the ABS
activate immediately if you are trying
to stop on snow or ice.
If the ABS indicator comes on, the
anti-lock f unction of the braking
system has shut down. The brakes
still work like a conventional system,
but without anti-lock. You should
have the dealer inspect your vehicle
as soon as possible.
You should never pump the brake pedal.

If the ABS indicator and the break
system indicator come on together
and the parking break is f ully
released, the front-to-rear braking
distribution system may also shut
down.
Test your brakes as instructed on
page . If the brakes f eel normal,
drive slowly and have your vehicle
repaired by your Acura dealer as
soon as possible. Avoid sudden hard
braking which could cause the rear
wheels to lock up and possibly lead
to a loss of control.It only helps with the
steering control during braking.
such as trying to take a
corner too f ast or making a sudden
lane change. Always drive at a safe
speed f or the road and weather
conditions. on loose or
uneven surf aces, such as gravel or
snow, than a vehicle without anti-
lock.
Always steer moderately
when you are braking hard. Severe
or sharp steering wheel movement
can still cause your vehicle to veer
into oncoming traffic or off the road.

Important Saf ety Reminders
A BS does not reduce the time or
distance it takes to stop the
vehicle.
A BS will not prevent a skid that
results f rom changing direction
abruptly, A vehicle with A BS may require a
longer distance to stop
A BS cannot prevent a loss of
stability.

The weight that the tongue of a f ully
loaded trailer puts on the hitch
shouldbe5to10percentof thetotal
trailer weight f or boat trailers, and 8
to 15 percent of total trailer weight
f or all other trailers. See page f or
limits f or your towing situation.Too much tongue load reduces f ront-
tire traction and steering control.
Too little tongue load can make the
trailer unstable and cause it to sway.
Park the vehicle on level ground.
Measure and record the distance
from the ground to the bottom of
the trailer hitch.
Connect the f ully loaded trailer to
the hitch.
Measure again f rom the ground to
the same spot on the bottom of the
hitch.
Subtract the second measurement
f rom the f irst measurement. Ref er
to Fig. 1. If thedifferenceis:
1 ½’’ = 150 lbs (68 kg)
2 ¼’’ = 250 lbs (114 kg)3’’ = 350 lbs (159 kg)
3 ¾’’ = 450 lbs (204 kg) 4’’ = over 450 lbs (204 kg)
If thedifferenceismorethan4’’
you have too much tongue load
at the rear. Move or remove
cargo f rom the trailer and the
vehicle, and measure again.
If the estimated trailer weight and
tongue load do not exceed the limits,
drive your trailer to a public scale
f ully loaded with all occupants and
cargo you plan to take on the road.

Towing generally requires a variety
of supplemental equipment. To
ensure the best quality, we
recommend that you purchase Acura
equipment whenever possible.
Discuss any additional needs with
your trailer sales or rental agency,
and make sure all equipment is
properly installed, maintained, and
also meets state regulations.
A weight distributing hitch is not
recommended f or use with your
MDX.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
and can catch the trailer if it
becomes unhitched. Leave enough
slack to allow the trailer to turn
corners easily, but 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.
Acura requires that any trailer with a
total trailer weight of 1,000 lbs (455
kg) or more have its own brakes.
There are two common types of
trailer brakes: surge and electric.
Surge brakes are common f or boat
trailers, since the brakes will get wet.
Electric brakes must be
electronically actuated. Do not
attempt to tap into your vehicle’s
hydraulic system. See your brake
manuf acturer f or more inf ormation
on installing electric brakes.
Many states and provinces require
special exterior mirrors when towing
a trailer. Even if they don’t, you
should install special mirrors if you
cannot clearly see behind you, or if
the trailer creates a blind spot.
We strongly recommend that you
have your Acura dealer install an
Acura hitch and use the required
f luid coolers. Using non-Acura
equipment may result in serious
damage to your vehicle. T owing Equipment and

When driving with a f ix-sided (e.g.
camper, utility) trailer, do not
exceed 55 mph (88 km/h). At
higher speeds, the trailer may
sway or affect vehicle handling.
Whenbeingpassedbyatruckor
large vehicle, cross-winds and air
turbulence can disrupt your
steering and cause your trailer to
sway. Keep a constant speed, steer
straight ahead, and do not try to
make quick steering or braking
corrections.
Do not park on an incline unless it
is unavoidable. If you must, turn
the vehicle’s wheels toward the
curb on a downhill or away f rom
the curb on an uphill. Af ter
parking, place wheel chocks at
each trailer tire on the downhill
side.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
to get the trailer to move to the lef t,
andturnthewheelrighttomovethe
trailer to the right.
If the vehicle’s wheels 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.
When climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, reduce speed
and, if necessary, pull to the side of
the road and let the engine cool.
If the transmission shif ts f requently
while going up a hill, shif t down one
gear.
If youmuststopwhenfacinguphill,
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.

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
engine run f or three minutes, then
turn it off.
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.)
