■Trailer light
Trailer lights and equipment must comply with federal, state, province/territory, and
local regulations. Check with your local trailer sales or rental agency for the
requirements in the area where you plan to tow.
We recommend that you have a dealer instal l a Acura wiring harness and converter.
They are designed for your vehicle.
■Hitches
Read the trailer manufacturer’s instructions , and select the appropriate draw bar for
the height of the trailer you will be towing.
■Weight distribution hitches
Your vehicle is designed to tow without the need for a load distributing hitch. If you
wish to use one, please consult your trailer maker for proper installation and set-up.
Improper set-up could degrade the handling , stability, and braking performance of
your vehicle.

uuTowing a Trailer uTrailer Stability Assist
Driving
Trailer Stability Assist
Helps to stabilize the vehicle and tra iler when the trailer severely sways.
■How trailer stability assist works
When the vehicle and trailer become unstab le while driving, trailer stability assist
determines the cause. If the trailer oscill ation is detected as the cause, and the
swaying increases, the system applies the brak es or controls engine output to reduce
vehicle speed.
Both the vehicle and trailer brake lights come on automatically if you brake to
reduce vehicle speed.
1 Trailer Stability Assist
Trailer stability assist is not a function that prevents
the vehicle and trailer from swaying. Avoid high
speeds, abrupt steering, improper trailer load, and
sudden braking to keep the trailer from swaying.
When swayed too severely, the system becomes
ineffective, and you may lose control of your vehicle,
causing the trailer to roll over or get damaged. 2 Driving Safely with a Trailer P. 463
Trailer towing sway is caused by:
•Crosswinds
•Improper towbar down load
•Excessive Speed
The VSA ® system indicator blinks during the trailer
stability assist operation. 2 VSA ® Operation P. 520

Driving Safely with a Trailer
• Have the trailer properly servic ed and keep it in good condition.
• Make sure that all the weights and load in the vehicle and trailer are within limits.
2Towing Load Limits P. 454
•When towing more than 3,500 lbs (1,590 kg), use of gasoline with a pump
octane number of 91 or higher is recommended.
u Towing performance can be affected by high altitude, high temperature, or
steep uphill.
• Securely attach the hitch, safety chains, and other necessary parts to the trailer.
• Securely store all the items in and on the tra iler so that they do not shift while
driving.
• Check if the lights and brakes on the trailer are working properly.
• Check the pressures of the traile r tires, including the spare.
• Turn off Auto Idle Stop sy stem using Auto Idle Stop OFF button. The trailer
weight can affect your vehicle’s brake effectiveness if Auto Idle Stop is activated
on a hill while towing a trailer.
• Drive slower than normal.
• Obey posted speed limits fo r vehicles with trailers.
• Use the
(D position when towing a trailer on level roads.
■Things You Need To Know Before Towing a Trailer
■Towing Speeds and Gears
1Driving Safely with a Trailer
Parking
In addition to the normal precautions, place wheel
chocks at each of the trailer’s tires.
1Towing Speeds and Gears
When towing a fixed-sided trailer (e.g., camper), do
not exceed 55 mph (88 km/h).
At higher speeds, the trai ler may sway or affect
vehicle handling.

meters).
When starting the engine in cold weather, turn off all
electrical accessories such as the lights, climate
control system, and rear de fogger in order to reduce
battery drain.
If you live in a region where winter is extremely cold,
an engine block heater will improve starting and
warming of the engine. Cons ult a dealer for details.
If exhaust system sounds abnormal or you can smell
exhaust gas inside the vehi cle, have your vehicle
checked by a dealer. There may be a problem with

Driving
Adaptive Cruise Control (ACC) with Low Speed
Follow (LSF)
Helps maintain a constant vehicle speed an d a set following-interval behind a vehicle
detected ahead of yours and, if the detect ed vehicle comes to a stop, can decelerate
and stop your vehicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with LSF slows your vehicle by applying the brakes, your vehicle’s brake
lights will illuminate.
1 Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)
Important Reminder
As with any system, there are limits to ACC with LSF.
Use the brake pedal whenever necessary, and always

uuWhen Driving uAdaptive Cruise Control (ACC) with Low Speed Follow (LSF)
Driving
■There is a vehicle ahead
ACC with LSF monitors if a vehicle ahead of you enters the ACC with LSF range. If a
vehicle is detected doing so, the ACC with LSF system maintains or decelerates your
vehicle’s set speed in order to keep the ve hicle’s set following-interval from the
vehicle ahead.
2 To Set or Change Following-interval P. 501
When a vehicle whose speed is slower than
your set speed is detected in front of you, your
vehicle starts to slow down.
■When in Operation1When in Operation
If the vehicle detected ahead of you slows down
abruptly, or if a nother vehicle is de tected cutting in
front of you, the beep er sounds and a message
appears on the MID, and the head-up warning lights

come on.
Depress the brake pedal, and keep an appropriate
interval from the vehicle ahead.
Even if the interval betw een your vehicle and the
vehicle detected ahead is short, ACC with LSF may
start accelerating your vehicle under the following
circumstances:
•The vehicle ahead of you is going at almost the
same speed as, or faster than, your vehicle.
•A vehicle that cuts in front of you is going faster
than your vehicle, gradua lly increasing the interval
between the vehicles.
