Towing a Trailer
Towing Preparation
Your vehicle can tow a trailer if you carefully observe the load limits, use the proper
equipment, and follow the towing guidelin es. Check the load limits before driving.
■Total trailer weight
Do not exceed the maximum allowable
weight of the trailer, cargo, and everything in
or on it shown in the table.
Towing loads in excess of this can seriously
affect vehicle handling and performance and
can damage the engine and drivetrain.
Each weight limit is calculated based on the following conditions:
• Occupants fill seats from the front of the vehicle to the back
• Each occupant weights 150 lbs (68 kg)
• Each occupant has 17.6 lbs (8 kg) of cargo in the cargo area
Any additional weight, cargo or accessori es reduce the maximum trailer weight and
maximum tongue load.
■Towing Load Limits1 Towing Load Limits
Check if all loads are within limits at a public scale.
If a public scale is not available, add the estimated
weight of your cargo load to the weight of your
trailer (as quoted by the manufacturer), and then
measure the tongue load with an appropriate scale or
tongue gauge or estima te it based on cargo
distribution.
Refer to the trailer owner’s manual for additional
information.
Break-in Period
Avoid towing a trailer duri ng your vehicle’s first 600
miles (1,000 km).
Never exceed the gross weight ratings.
Gross weight information 2 Vehicle Specifications P. 676
3WARNING
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.

■How to weigh the trailer lo ads using the public scale
Check each weight in the order indicated as shown.
Refer to the table on the right for each we ight’s limit except for the tongue load.
2Tongue load P. 453
•If you cannot weigh the rear axle, subtract 1 from 2.
• The maximum gross combined weight (4) decreases by 2% for every 1,000 feet
(305 meters) of elevation.
• To calculate the tongue load, subtract 5 from 6.
• Refer to the trailer owner’s manu al for additional information.
1How to weigh the trailer loads using the public scale
Fully load the vehicle and trailer. An attendant who
watches the scale is needed as all occupants should
stay in the vehicle.
If a public scale is not available, add the estimated
weight of your cargo load to the weight of your
trailer (as quoted by the manufacturer), and then
measure the tongue load with an appropriate scale or
tongue gauge or estima te it based on cargo
distribution. Weight limit for 2WD models AWD models

■Trailer brakes
Recommended for any trailer with a total weight of 1,000 lbs (450 kg) or more:
There are two common types of trailer brake s: surge and electric. Surge brakes are
common for boat trailers, since the brakes will get wet.
If you choose electric brakes, be sure th ey are electronically actuated. Do not
attempt to attach trailer brakes to your ve hicle’s hydraulic system, as it will lower
braking effectiveness and create a potential hazard.
The 4-pin gray connector installed in your vehicle has all of the circuits required to
install most electric trailer brake controllers.
Have a qualified mechanic install your trailer
brake controller following the trailer brake
controller manufacturer’s instructions. Failure
to properly install the trailer brake controller
may increase the distance it takes for you to
stop your vehicle when towing a trailer.1 Trailer brakes
The 4-pin gray connector is located under the left

■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 inst all 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 cons ult your trailer maker for proper installation and set-up.
Improper set-up could degrade the handling, stability, and braking performance of
your vehicle.

Driving Safely with a Trailer
• Have the trailer properly serviced 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. 452
•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 trailer 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 the Auto Idle Stop syst em using the Auto Idle Stop OFF button. The
trailer weight can affect your vehicle’s br ake effectiveness if Auto Idle Stop is
activated on a hill while towing a trailer.
• Drive slower than normal.
• Obey posted speed limits for 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.

Fuel Economy and CO2 Emissions
Improving Fuel Economy and Reducing CO2
Emissions
Achieving fuel economy and reducing CO2 emissions is dependent on several
factors, including driving conditions, load weight, idling time, driving habits, and
vehicle condition. Depending on these and other factors, you may not achieve the
rated fuel economy of this vehicle.
You can optimize your fuel economy with proper maintenance of your vehicle.
Always maintain your vehicle in accordance with the messages displayed on the
MID.
• Use the recommended viscosity engine oil.
2 Recommended Engine Oil P. 584
•Maintain the specified tire pressure.
• Do not load the vehicl e with excess cargo.
• Keep your vehicle clean. A buildup of snow or mud on your vehicle’s underside
adds weight and increases wind resistance.
■Maintenance and Fuel Economy
1Improving Fuel Economy and Reducing CO2 Emissions
Direct calculation is the recommended method to
determine actual fuel consumed while driving.
In Canada, posted fuel economy numbers are
established following a simulated test. For more
