suspension Acura MDX 2013 Owner's Manual

Modifying Your Vehicle
Removing parts from your vehicle, or
replacing components with non-
Acura components could seriously
affect your vehicle's handling,
stability, and reliability.
Some examples are:●Lowering your vehicle with a non-
Acura suspension kit that
significantly reduces ground
clearance can allow the
undercarriage to hit speed bumps
or other raised objects, which
could cause the airbags to deploy.●Raising your vehicle with a non-
Acura suspension kit can affect the
handling and stability.●Non-Acura wheels, because they
are a universal design, can cause
excessive stress on suspension
components and will not be
compatible with the tire pressure
monitoring system (TPMS).
●Larger or smaller wheels and tires
can interfere with the operation of
your vehicle's anti-lock brakes and
other systems.
Modifying your steering wheel or
any other part of your vehicle's safety
features can make the systems
ineffective.
If you plan to modify your vehicle,
consult your dealer.

Certain conditions may cause the
radar aim to be temporarily out of
proper range, such as the following
two examples:●Your vehicle is tilted because of a
heavy load in the rear or from
modifications to the suspension.
Do not overload your vehicle (see
Carrying Cargo on page 433), and
do not make any modifications to
the suspension (see Accessories
and Modifications on page 431).●The tires are not correctly
maintained. Always make sure the
tire pressures are correct (see
page 540), and that the tires are
the correct size and in good
condition (see Tires on page 540).Collision Alert
If the system senses a likely collision
with a vehicle or object ahead of you,
it alerts you with a visual alert or a
combination of a visual alert and an
audible alert.
The visual alert is an amber colored
BRAKE message that flashes on the
multi-information display, the audible
alert is a constant beeping sound. If
one or more of the alerts come on,
take the appropriate means to
prevent a collision (apply the brakes,
change lanes, etc.).

This device complies with the
appropriate requirements or the
required standards. See page 592 for
more information.Active Damper System
If equippedThe active damper system is always
on, constantly adjusting your
vehicle's dampers to the best settings
for current road conditions along
with vehicle speed and handling
inputs.The system uses electrically
controlled dampers to enhance
handling precision, vehicle
composure, tire to road adhesion and
rough road ride comfort isolation.
The system reacts to inputs from
various electronic sensors to give
exactly the right amount of
suspension damping to provide
optimal ride comfort and handling.

Pre-Tow Checklist
When preparing to tow, and before
driving away, be sure to check the
following:●The vehicle has been properly
serviced, and the suspension and
the cooling system are in good
operating condition.●The trailer has been properly
serviced and is in good condition.●All weights and loads are within
limits.●The hitch, safety chains, and any
other attachments are secure.●All items on and in the trailer are
properly secured and cannot shift
while you drive.
●The lights and brakes on your
vehicle and the trailer are working
properly.●Your vehicle tires and spare are in
good condition and properly
inflated.●The trailer tires and spare are in
good condition and inflated as
recommended by the trailer
maker.Driving Safely With a Trailer
The added weight, length, and
height of a trailer will affect your
vehicle's handling and performance,
so driving with a trailer requires
some special driving skills and
techniques.
For your safety and the safety of
others, take time to practice driving
maneuvers before heading for the
open road, and follow the guidelines
in this section.

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.

●Rotate tires
2●Replace air cleaner element
If you drive in dusty conditions, replace every 15,000
miles (24,000 km).●Replace dust and pollen filter
If you drive primarily in urban areas that have high
concentrations of soot in the air from industry and from
diesel-powered vehicles, replace every 15,000 miles
(24,000 km).●Inspect drive belt
3●Replace transmission and transfer fluid
4●Replace spark plugs●Replace timing belt and inspect water pump
If you drive regularly in very high temperatures (over
110°F, 43°C), in very low temperatures (under－20°F,－
29°C), or towing a trailer, replace every 60,000 miles (U.
S.)/100,000 km (Canada).●Inspect valve clearance
5●Replace engine coolant
6●Replace rear differential fluid
Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher level of
mechanical (shear) stress to fluid. This requires
differential fluid changes more frequently than
recommended by the Maintenance Minder. If you
regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles (12,000
km), then every 15,000 miles (24,000 km).

Snow Tires
If you mount snow tires on your
vehicle, make sure they are radial
tires of the same size and load range
as the original tires. Mount snow
tires on all four wheels. The traction
provided by snow tires on dry roads
may be lower than your original tires.
Check with the tire dealer for
maximum speed recommendations.
Tire Chains
Mount tire chains on your tires when
required by driving conditions or
local laws. Install them only on the
front tires.
Because your vehicle has limited tire
clearance, Acura strongly
recommends using the chains listed
below.
SCC Super Z-6＃SC 435When installing chains, follow the
manufacturer's instructions and
mount them as tightly as you can.
Drive slowly with chains installed. If
you hear them contacting the body
or chassis, stop and investigate.
Make sure the chains are installed
tightly, and that they are not
contacting the brake lines or
suspension. Remove the chains as
soon as you start driving on cleared
roads.
Using the wrong chains, or not
properly installing chains, can
damage the brake lines and
cause a crash in which you can
be seriously injured or killed.
Follow all instructions in this
owner's manual regarding the
selection and use of tire chains.
Traction devices that are the wrong size
or improperly installed can damage
your vehicle's brake lines, suspension,
body, and wheels. Stop driving if they
are hitting any part of the vehicle.
Wheels
Clean the wheels as you would the
rest of the exterior. Wash them with
the same solution, and rinse them
thoroughly.
Aluminum alloy wheels have a
protective clear-coat that keeps the
aluminum from corroding and
tarnishing. Cleaning the wheels with
harsh chemicals (including some
commercial wheel cleaners) or a stiff
brush can damage the clear-coat. To
clean the wheels, use a mild
detergent and a soft brush or sponge.
