wheel ACURA ZDX 2010 Repair Manual

Your vehicle is equipped with disc
brakes at all four wheels. A power
assist helps reduce the effort needed
on the brake pedal. The emergency
brake assist system increases the
stopping force 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 foot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their effectiveness
and reduces brake pad life. In
addition, fuel economy can be
reduced. It also keeps your brake
lights on all the time, confusing
drivers behind you.Constant application of the brakes
when going down a long hill builds
up heat and reduces their
effectiveness. Use the engine to
assist the brakes by taking your foot
off the accelerator and downshifting
to a lower gear.
Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they feel
normal. If not, apply them gently and
frequently until they do. Be extra
cautious in your driving.
Braking System Design
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the left-front brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
Brake Wear Indicators
All four 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 for
the brakes to occasionally squeal or
squeak when you apply them.

The anti-lock brake system (ABS)
helps prevent the wheels from
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.You should never pump the brake pedal.Let the ABS work for you by always
keeping firm, steady pressure on the
brake pedal. This is sometimes
referred to as‘‘stomp and steer. ’’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.
ABS Indicator
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 vehicle as
soon as possible.
You will also see a ‘‘CHECK ABS
SYSTEM ’’message on the multi-
information display (see page 90).
If the indicator comes on while
driving, test the brakes as instructed
on page 594.

ProCarManuals.com

If the ABS indicator and the brake
system indicator come on together,
and the parking brake is fully
released, the EBD system may also
be shut down.
Test your brakes as instructed on
page 594. If the brakes feel 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.Important Safety Reminders
ABS does not reduce the time or
distance it takes to stop the
vehicle.
It only helps with steering
control during braking.
ABS will not prevent a skid that
results from changing direction
abruptly, such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather
conditions. ABS cannot prevent a loss of
stability.
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.
A vehicle with ABS may require a
longer distance to stop on loose or
uneven surfaces, such as gravel or
snow, than a vehicle without anti-
lock.

OverviewIf equippedThe collision mitigation braking
system™(CMBS ™) can assist you
when there is a possibility of your
vehicle hitting the vehicle in front of
you. It is designed to reduce the
speed of your vehicle before an
unavoidable collision occurs and, if
possible, to alert you to a potential
collision while there is time to
prevent it. Here is a brief description
of what the CMBS can do:●When your speed is above 10 mph
(16 km/h), the CMBS radar
sensor in the front grille can sense
a vehicle ahead of you. When your
vehicle gets too close to the
vehicle ahead of you, the system
may activate a warning beep,
causing automatic application of
the brakes, and causing the e-
pretensioners to tighten the front
seat belts (see page 24).
●The CMBS does not activate if the
speed difference between the two
vehicles is less than 10 mph (16
km/h). CMBS may also not
activate if you turn the steering
wheel to avoid the collision.
When the CMBS activates, the brake
lights also come on.
The CMBS consists of a radar sensor
in the front grille, a brake actuator in
the engine compartment, an
indicator on the instrument panel,
seat belt e-pretensioners on the front
seats, and an on/off switch under the
driver's side vent.RADAR SENSOR

Important Safety Reminder
The main purpose of the CMBS is to
reduce the severity of injuries caused
by an unavoidable collision. While
the CMBS may help to alert you and
minimize the severity of a collision, it
may not activate in every dangerous
situation.
Even with the CMBS, it is still your
responsibility to operate the brake
pedal and steering wheel
appropriately, according to the
driving conditions.

VSA and Tire Sizes
Driving with varying tire or wheel
sizes may cause the VSA to
malfunction. When replacing tires,
make sure they are of the same size
and type as your original tires (see
page 571).
If you install winter tires, make sure
they are the same size as those that
were originally supplied with your
vehicle. Exercise the same caution
during winter driving as you would if
your vehicle was not equipped with
VSA.Hill Start Assist
Your vehicle is equipped with a hill
start assist feature to help prevent
the vehicle from rolling on inclines as
you move your foot from the brake
pedal to the accelerator.
To activate hill start assist, you must
come to a complete stop and make
sure the shift lever is either in D or S
when facing uphill, or reverse when
facing downhill.
This feature begins working a few
seconds after you are in the correct
gear position. Release the brake
pedal. The brakes remain engaged
briefly to keep the vehicle from
rolling forward or backward. Gently
apply the accelerator pedal as in
normal driving. Hill start assist will
release brake pressure gradually as
you accelerate.Hill start assist may not prevent your
vehicle from rolling downhill on a
very steep or slippery slope, and will
not operate on small inclines.
Hill start assist is not a replacement
for the parking brake. If parking your
vehicle, ensure that the transmission
is in park, and/or the parking brake
is fully applied before exiting the
vehicle.
If the VSA system indicator comes on
with a
‘‘CHECK HILL START
ASSIST SYSTEM ’’message on the
multi-information display, there may
be a problem with the hill start assist.
The VSA also may not function. Have
your vehicle inspected by your
dealer.
Hill start assist will still operate even
when VSA is switched off.Vehicle Stability Assist (VSA

Driving on HillsWhen climbing hills, closely watch
your temperature gauge. If it nears
the H (Hot) mark, turn the A/C off,
reduce speed and, if necessary, pull
to the side of the road to let the
engine cool.
When driving down hills, reduce
your speed, and shift down to S
position, or use the paddle shifters to
the lower gear (3 and 2) in the S
position. When towing a trailer, do
not‘‘ride ’’the brakes, and remember,
it will take longer to slow down and
stop when towing a trailer.
If you must stop when facing uphill,
use the foot brake or parking brake.
Do not try to hold the vehicle in place
by pressing on the accelerator, as
this can cause the automatic
transmission to overheat.
Handling Crosswinds and BuffetingCrosswinds 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.Backing UpAlways drive slowly and have
someone guide you when backing
up. Grip the
bottom
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.
ParkingFollow all normal precautions 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. Towing Your Vehicle
Your vehicle is not designed to be
towed behind a motor home. If your
vehicle needs to be towed in an
emergency, see page 602.

General Information
Your vehicle has been designed
primarily for use on pavement. But
its higher ground clearance and
super handling-all wheel drive
(SH-AWD) system allow you to
occasionally travel on unpaved roads,
to campgrounds, picnic sites, and
similar locations. It is not designed
for trailblazing, mountain climbing,
or other challenging off-road
activities.
If you decide to drive on unpaved
roads, you will find that it requires
somewhat different driving skills.
Your vehicle will also handle
somewhat differently than it does on
pavement. Be sure to pay extra
attention to the precautions and tips
in this section, and get acquainted
with your vehicle before leaving the
pavement.
Improperly operating this
vehicle on or off-pavement can
cause a crash or rollover in
which you and your passengers
could be seriously injured or
killed.●Follow all instructions and
guidelines in this owner's
manual.●Keep your speed low, and
don't drive faster than
conditions permit.Important Safety Precautions
To avoid loss of control or rollover,
be sure to follow all precautions and
recommendations.
●Be sure to store cargo properly
and do not exceed your cargo load
limits (see page 466 and 522).●Whenever you drive, make sure
you and your passengers always
wear seat belts.●Keep your speed low, and never go
faster than the conditions allow.●It's up to you to continually assess
the situation and drive within the
limits.

Check Out Your Vehicle
Before you leave the pavement, be
sure to do all scheduled maintenance
and service, and inspect your vehicle
for any problems. Pay special
attention to the condition of the tires,
and check the tire pressures.
After you return to the pavement,
carefully inspect your vehicle to
make sure there is no damage that
could make driving it unsafe.
Recheck the condition of the tires
and the tire pressures.
Remember
The route presents limits (too steep
or bumpy roads). You have limits
(driving skill and comfort). And your
vehicle has limits (traction, stability,
and power).
Driving off-highway can be
hazardous if you fail to recognize
limits and take the proper
precautions.Accelerating and Braking
For better traction on all surfaces,
accelerate slowly and gradually build
up speed. If you try to start too fast
on wet soil, mud, snow, or ice, you
might not have enough traction to
get underway, and you may dig
yourself a hole. Starting with the shift
lever in the D position will help you
have a smoother start on snow or ice.
Keep in mind that you will usually
need more time and distance to
brake to a stop on unpaved surfaces.
Avoid hard braking. Do not
‘‘pump ’’
the brakes; let the anti-lock braking
system pump them for you.
Avoiding Obstacles
Debris in the road can damage your
suspension or other components.
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. Driving on Slopes
If you can't clearly see all conditions
or obstacles on a slope, walk the
slope before you drive on it. If you
have any doubt whether or not you
can safely drive on the slope, don't
do it. Find another route.
If you are driving up a hill and find
that you cannot continue,
do not try to
turn around.
Your vehicle could roll
over. Slowly back down the hill,
following the same route you took up
the hill.
Crossing a Stream
Before driving through water, stop,
get out if necessary, and make sure
that:
●The water is not deep enough to
cover your wheel hubs, axles, or
exhaust pipe. You could stall and
not be able to restart your engine.
The water can also damage
important vehicle components.

●The banks are sloped so you can
drive out.●The water is not flowing too fast.
Deep rushing water can sweep you
downstream. Even very shallow
rushing water can wash the
ground from under your tires and
cause you to lose traction and
possibly roll over.●The banks and surface under the
water provide good traction. The
water may hide hazards such as
rocks, holes, or mud.
If you decide it is safe to drive
through water, choose a suitable
speed, and proceed without shifting,
changing speeds, stopping, or
shutting off the engine.
After driving through water, test your
brakes. If they got wet, gently
‘‘ pump ’’them while driving slowly
until they operate normally. If the water is deeper than the wheel
hubs, some additional service may be
required. This service is not covered
by your warranties.
If You Get Stuck
If you get stuck, carefully try to go in
the direction (forward or reverse)
that you think will get you unstuck.
Do not spin the tires at high speeds.
It will not help you get out and may
cause damage to the transmission or
SH-AWD system.
If you are still unable to free yourself,
your vehicle is equipped with front
and rear tow hooks designed for this
purpose.
Use a nylon strap to attach your
vehicle to the recovery vehicle and
carefully take out the slack in the
strap. Once the strap is tight, the
recovery vehicle should apply force.
Remember that the recovery vehicle
needs good traction to avoid
becoming stuck, too.You should never use a jack to try to
get unstuck. Your vehicle could
easily slip off the jack and hurt you or
someone else.Off-Highway Driving Guidelines53009/10/28 17:15:37 10 ACURA ZDX KA KC New North America Own 50 31SZN600 enu
