2012 Acura RDX suspension

Improper accessories or
modifications can affect your
vehicle's handling, stability, and
performance, and cause a
crash in which you can be hurt
or killed.
Follow all instructions in this
owner's manual regarding
accessories and modifications.
When properly installed, cellular
phones, alarms, two-way radios, and
low-powered audio systems should
not interfere with your vehicle's
computer controlled systems, such
as your airbags, anti-lock brakes, and
tire pressure monitoring system. Before installing any accessory:
●Make sure the accessory does not
obscure any lights, or interfere
with proper vehicle operation or
performance.●Be sure electronic accessories do
not overload electrical circuits (see
page 469) or interfere with proper
operation of your vehicle.●Before installing any electronic
accessory, have the installer
contact your dealer for assistance.
If possible, have your dealer
inspect the final installation.●Do not install accessories on the
side pillars or across the rear
windows. Accessories installed in
these areas may interfere with
proper operation of the side
curtain airbags.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.
Here are some examples:
●Lowering the 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, stability, and reliability.

●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.Accessories and Modifications36411/06/16 17:42:51 12 ACURA RDX MMC North America Owner's M 50 31STK650 enu

Since lighting and wiring vary by
trailer type and brand, you should
have a qualified technician install a
suitable connector between the
vehicle and the trailer. Improper
equipment or installation can cause
damage to your vehicle's electrical
system and affect your vehicle
warranty.
Additional Towing EquipmentMany states, Canadian provinces and
territories require special outside
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.
Ask your trailer sales or rental
agency if any other items are
recommended or required for your
towing situation.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,
cooling system, and lights are in
good operating condition.

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.

●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 filterIf 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
ᤳ 2fluid
Driving in mountainous areas at very low vehicle speeds
or trailer towing results in higher transmission and
transfer temperatures. This requires transmission and
transfer fluid changes more frequently than
recommended by the Maintenance Minder. If you
regularly drive your vehicle under these conditions, have
the transmission and transfer fluid changed at 60,000
miles (100,000 km), then every 30,000 miles (48,000 km).

●Replace spark plugs●Inspect valve clearance
5●Replace engine coolant
6●Replace rear differential fluid
ᤳ 2
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).

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, made by Security Chain
Company (SCC).
Cable type: Shur Grip Z
SZ343When installing cables, follow the
manufacturer's instructions, and
mount them as tight as you can.
Make sure they are not contacting
the brake lines or suspension. Drive
slowly with them installed. If you
hear them coming into contact with
the body or chassis, stop and
investigate. Remove them as soon as
you begin driving on cleared roads.
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.
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.
