2011 Acura RDX Owner's Manual

Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.
VSA OFF Switch
In certain unusual conditions when
your vehicle gets stuck in shallow
mud or fresh snow, it may be easier
to free it with the VSA temporarily
switched off. When the VSA system
is off, the traction control system is
also off. You should only attempt to
free your vehicle with the VSA off if
you are not able to free it when the
VSA is on.
Immediately after freeing your
vehicle, be sure to switch the VSA on
again. We do not recommend driving
your vehicle with the VSA and
traction control systems switched off.
This switch is under the driver's side
vent. To turn the VSA system on and
off, press and hold it until you hear a
beep.
When VSA is off, the VSA activation
indicator comes on as a reminder.
Press and hold the switch again. It
turns the system back on.
VSA is turned on every time you start
the engine, even if you turned it off
the last time you drove the vehicle.VSA and Tire Sizes
Driving with varying tire or wheel
sizes may cause the VSA to
malfunction. When replacing tires,
make sure they are the same size
and type as your original tires (see
page 448).
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.

Your vehicle has been designed
primarily to carry passengers and
their cargo. You can also use it to tow
a trailer if you carefully observe the
load limits, use the proper
equipment, and follow the guidelines
in this section.Break-In PeriodAvoid towing a trailer during your
vehicle's first 600 miles (1,000 km)
(see page 352).Be sure to read the
Off-Highway
Driving Guidelines section on page
405 if you plan to tow off paved
surfaces.
Exceeding any load limit or
improperly loading your vehicle
and trailer can cause a crash in
which you can be seriously hurt
or killed.
Check the loading of your
vehicle and trailer carefully
before starting to drive. Load Limits
Total Trailer Weight:
The maximum
allowable weight of the trailer and
everything in or on it must not
exceed 1,500 lbs (680 kg). Towing a
load that is too heavy can seriously
affect your vehicle's handling and
performance. It can also damage the
engine and drivetrain.

Tongue Load:The weight that the
tongue of a fully-loaded trailer puts
on the hitch should be approximately
10% of the total trailer weight. 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. To achieve a proper tongue load,
start by loading 60% of the load
toward the front of the trailer and 40%
toward the rear, then re-adjust the
load as needed.

Checking Loads
The best way to confirm that all loads
are within limits is to check them at a
public scale. For public scales in your
area, check your local phone book,
or contact your trailer dealer or
rental agency for assistance.
If you cannot get to a public scale,
you can estimate the total trailer
weight by adding the weight of your
trailer (as quoted by the
manufacturer) with everything in or
on the trailer.
If you normally pull the same load
each time you tow a trailer, you can
use a suitable scale or a special
tongue load gauge to check the
tongue load the first time you set up
a towing combination (a fully loaded
vehicle and trailer), then recheck the
tongue load whenever the conditions
change.Towing Equipment and
Accessories
Towing can require a variety of
equipment, depending on the size of
your trailer, how it will be used, how
much load you are towing, and
where you tow.
Discuss your needs with your trailer
sales or rental agency, and follow the
guidelines in this section. Also make
sure that all equipment is properly
installed and maintained, and that it
meets federal, state, provincial,
territorial and local regulations.
HitchesAny hitch used on your vehicle must
be properly bolted to the underbody.Safety ChainsAlways use safety chains when you
tow a trailer. Make sure the chains
are secured to the trailer and hitch,
and that they cross under the tongue
and can catch the trailer if it becomes
unhitched. Leave enough slack to
allow the trailer to turn corners
easily, but do not let the chains drag
on the ground.

Trailer BrakesAcura recommends that any trailer
with a total trailer weight of 1,000 lbs
(450 kg) or more has its own brakes.
There are two common types of
trailer brakes: surge and electric.
Surge brakes are common for boat
trailers, since the brakes will get wet.
If you choose electric brakes, be sure
they are electronically actuated. Do
not attempt to tap into your vehicle's
hydraulic system. No matter how
successful it may seem, any attempt
to attach trailer brakes to your
vehicle's hydraulic system will lower
braking effectiveness and create a
potential hazard.
See your trailer dealer or rental
agency for more information on
installing electric brakes.
Trailer LightsTrailer lights and equipment must
comply with federal, provincial,
territorial, and local regulations.
Check with your local trailer sales or
rental agencies for the requirements
in the area where you plan to tow,
and use only equipment designed for
your vehicle.
Your vehicle has a trailer lighting
connector located under the right
side tool case in the cargo area. Refer
to the drawing above for the wiring
color code and purpose of each pin.

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.

●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 in or on 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
properly inflated, and the trailer
tires and spare are 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.

Towing Speeds and GearsDrive slower than normal in all
driving situations, and obey posted
speed limits for vehicles with trailers.
Use the D position when towing a
trailer on level roads. See‘‘
Driving on
Hills
’’ in the next column for
additional gear information. Do not
exceed 55 mph (88 km/h). At higher
speeds, the trailer may sway or affect
vehicle handling. When driving uphill and downhill,
use the S position (without using the
paddle shifters) to provide the proper
engine power and engine braking on
each gear. You can also use the
paddle shifters. In this case, select
third, second, or first gear with the
paddle shifter; depending on the
vehicle speeds and road condition.
Do not use fourth and fifth gears.
The recommended speed range for
each gear position is shown in the
table.
Gear position Speed range 10 －38 mph
(0 － 60 km/h)
2, 3 19 －62 mph
(30 －100 km/h)
Making Turns and BrakingMake turns more slowly and wider
than normal. The trailer tracks a
smaller arc than your vehicle, and it
can hit or run over something the
vehicle misses. Allow more time and
distance for braking. Do not brake or
turn suddenly as this could cause the
trailer to jackknife or turn over.
