engine Acura MDX 2002 Owner's Guide

The Variable Torque Management
4WD System (VTM-4) automatically
transf ers varying amounts of engine
torque to the rear wheels under low
traction conditions.If more traction is needed when your
MDX is stuck or is likely to become
stuck, you can use the VTM-4 Lock
button to increase torque to the rear
wheels. As soon as this feature is no
longer needed, press the VTM-4
Lock button again to disengage the
VTM-4 Lock.

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 noises and
vibration can also result.

When the brake pads need replacing,
you will hear a distinctive metallic
‘‘screeching’’ sound when you apply
the brakes. If you do not have the
brake pads replaced, they will begin
screeching all the time.
Your brakes may sometimes squeal
or squeak when you apply them
lightly. Do not conf use this with the
brakewearindicators.Theymakea
very audible ‘‘screeching.’’
Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by downshif ting to a lower
gear and taking your f oot of f the
accelerator pedal.
Check your brakes af ter driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Since a
longer distance is needed to stop
with wet brakes, be extra cautious
and alert in your driving.
Your Acura is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. The ABS helps
you retain steering control when
braking very hard.
Put your f oot on the brake pedal only
when you intend to brake. Resting
your f oot on the pedal keeps the
brakes applied lightly, causing them
to build up heat. Heat build-up can
reduce how well your brakes work. It
also keeps your brake lights on all
the time, conf using drivers behind
you.
All f our brakes have audible brake
wear indicators. Brake Wear Indicators

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

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

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

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.

Bef ore driving through water, stop
and make sure that:The water is never deep enough to
cover your wheel hubs, axles or
exhaust pipe. You could stall, and
not be able to restart the engine.
The water could also damage
important vehicle components. 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 are sloped so you can
drive out.
The banks and surf ace under the
water provide good traction. The
water may hide hazards such as
rocks, holes, or mud.
If you decide it’s saf e to drive
through water, choose a suitable
speed and engage VTM-4 Lock (see
page ), then proceed without
shif ting or changing speed. Do not
stop the vehicle or shut of f the
engine while trying to cross a stream.
After driving through water, test
your brakes. If the brakes got wet,
drive slowly while gently pumping
the brakes until they operate
normally.
If the water is deeper than the wheel
hubs, some additional service to the
engine, transmission and dif f erential
mayberequired.Thisserviceisnot

Bef ore you begin any maintenance,
make sure your vehicle is parked on
level ground and that the parking
brake is set. Also, be sure the engine
is of f . This will help to eliminate
several potential hazards:Be sure
there is adequate ventilation
whenever you operate the engine.
Let the
engine and exhaust system cool
bef ore touching any parts. Read the instructions before you
begin, and make sure you have the
tools and skills required.
To reduce the possibility of f ire or
explosion, be caref ul when working
around gasoline or batteries. Use a
commercially available degreaser or
parts cleaner, not gasoline, to clean
parts. Keep cigarettes, sparks, and
flames away from the battery and all
f uel-related parts.
Do
not run the engine unless in-
structed to do so. You should wear eye protection and
protective clothing when working
near the battery or when using
compressed air.

The Maintenance Schedule specif ies
how of ten you should have your
vehicle serviced and what things
need attention. It is essential that
you have your vehicle serviced as
scheduled to retain its high level of
saf ety, dependability, and emissions
control perf ormance.Service your vehicle according to the
time and mileage periods on one of
the Maintenance Schedules on the
f ollowing pages. Select the schedule
f or ‘‘Severe Conditions’’ if most of
your driving is done under one or
more of the conditions listed on that
page. Otherwise, f ollow the schedule
f or ‘‘Normal Conditions.’’
The services and time or distance
intervals shown in the maintenance
schedule assume you will use your
vehicle as normal transportation f or
passengers and their possessions.
You should also f ollow these
recommendations:
Avoid exceeding your vehicle’s
load limit. This puts excess stress
on the engine, brakes, and many
other parts of your vehicle. The
load limit is shown on the tire
inf ormation label on the driver’s
doorjamb. Operate your vehicle on
reasonable roads within the legal
speed limit.
Drive your vehicle regularly over a
distance of several miles
(kilometers).
Always use unleaded gasoline with
theproperoctanerating(seepage
