steering Acura MDX 2007 Owner's Guide

Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. Emergency
Brake Assist System increases the
stopping f orce when you depress the
brake pedal hard in an emergency
situation. The anti-lock brake system
(ABS) helps you retain steering
control when braking very hard.
Resting your f oot on the brake pedal
applies the brakes slightly. This
builds up heat, and reduces brake
ef f ectiveness and brake pad lif e. In
addition, f uel economy can be
reduced. It also keeps your brake
lights on all the time, conf using
drivers behind you.The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
All f our brakes have audible brake
wear indicators.
If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal f or
the brakes to occasionally squeal or
squeak when you apply them.
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 taking your f oot of f the
accelerator and downshif ting to a
lower gear.
Check the brakes after 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. Be extra
cautious in your driving.

The anti-lock brake system (ABS)
helpspreventthewheelsfrom
locking up, and helps you retain
steering control by pumping the
brakes rapidly, much faster than a
person can do it.
The electronic brake distribution
(EBD) system, which is part of the
ABS, also balances the front-to-rear
braking distribution according to
vehicle loading. If
this indicator comes on, the anti-
lock function of the braking system
has shut down. The brakes still work
like a conventional system, but
without anti-lock. You should have
your dealer inspect your vehic le as
soon as possible.
You
will feel 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 feel the ABS
activate immediately if you are trying
to stop on snow or ice.
If the indicator comes on while
driving, test the brakes as instructed
on page .
You
will also see a ‘‘CHECK ABS
SYSTEM’’ message on the multi-
info rmation display (see page ).
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.’’ 43281

uneven surfaces, such as gravel or
snow, than a vehicle without anti-
lock.
It
only helps with steering
control during braking.
If
the ABS indicator and the brake
system indicator come on together,
and the parking brake is fully

be shut down.
such as trying to take a
corn er too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather
conditions.
Always steer moderate ly
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.
Test your brakes as instructed on
page . If the brakes f eel normal,
drive slowly and have your vehicle
repaired by your 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.
The VSA indicator will come on
alongwiththeABSindicator.

The
weight that the tongue of a fully
loaded trailer puts on the hitch
shouldbe5to10percentofthetotal
trailer weight for boat trailers, and 8
to 15 percent of total trailer weight
for all other trailers. (See page
for limits for your towing
situation). Too much tongue load
reduces front-tire traction and
steering control. Too little tongue
load can make the trailer unstable and
cause it to sway.
The maximum
allowable weight of the vehicle, all
occupants, all accessories, all cargo,
and the tongue load must not exceed
2,888 lbs (1,310 kg) on the front axle,
and 3,175 lbs (1,440 kg) on the rear
axle. The
maximum
allowable weight of the vehicle, all
occupants, all accessories, all cargo
and the tongue load is 5,952 lbs
(2,700 kg).
The maximum allowable weight of
the trailer and everything in or on it
depends on the number of occupants
inyourvehicleandthetypeoftrailer
being towed (see page ).
Towing a trailer that is too heavy can
seriously af f ect your vehicle’s
handling and perf ormance. It can
also damage the engine and driven. The maximum
allowable weight of the f ully loaded
vehicle and trailer is 10,053 lbs
(4,560 kg) with the proper hitch. The
GCWR must be reduced 2 percent
f or every 1,000 f eet (305 meters) of
elevation.

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.

Under these conditions, trailer
stability assist begins to stabilize the
vehicl e/trailer combination by
reducing the vehicle speed. The
control unit sends signals to
selectively apply the brakes and
regulate the engine output. The
brake lights of your vehicle will be
turned on automatically by the
system even if you do not keep the
pressu re on the brake pedal.
Your
vehicle is equipped with trailer
stability assist function. This
function works on the same sensors
as the vehicle stability assist (VSA)
system. This function helps to
stabilize the vehicl e/trailer
combination when the trailer
severely sways or oscillates. For
more information of the VSA system,
see page .
When the brakes are applied, the
trailer’s brake lights come on along
wi th the vehicle brake lights.
When the trailer stability assist
activates, you will see the VSA
activation indicator blink. There may
also be some noise from the VSA
hydraulic system. Trailer
stability assist cannot prevent
a loss of control. Always reduce the
ve hicle speed and steer firmly. Do
not brake suddenly or make quick
steering motion. It could cause the
trailertojackknifeorturnoverand
the system becomes ineffective.
Trailer stability assist cannot prevent
swaying that can occur in crosswinds
and in normal and emergency
driving maneuvers. It helps only to
stabilize the vehicl e/trailer
combination in these conditions,
after the oscillation becomes severe.
If
the function detects the vehicle/
trailer instability, it checks if the
swaying is caused by the trailer, and
if the trailer swaying or oscillation is
increasing.
The vehicle/trailer combination is
more affected by crosswinds,
buffeting, and improper tongue load.
These conditions can make the
trailer unstable, and cause it to sway. Always obey the recommended
speed limits f or towing a trailer, see
page . Trailer stability assist will also be
inef f ective while driving at high
speed or towing a trailer with a high
center or gravity.

One
of the most convenient and
important features of the multi-
info rmation display on your vehicle
is the maintenance minder.
Based on engine operating
conditions and accumulated engine
revolutions, the onboard computer in
your vehicle calculates the remaining
engine oil life.
The system also displays the code
for other scheduled maintenance
items needing service. The
remaining engine oil life is
displayed according to the table
shown below.
