(4) The resulting figure equals the available amount of cargo and
luggage load capacity. For example, if the “XXX” amount
equals 1,400 lbs. and there will be five 150 lb. passengers in
your vehicle, the amount of av ailable cargo and luggage load
capacity is 650 lbs.
(1,400 - 750 (5 x 150) = 650 lbs.)
(5) Determine the combined weight of luggage and cargo being
loaded on the vehicle. That we ight may not safely exceed the
available cargo and luggage load capacity calculated in step 4.
(6) If your vehicle will be towing a tra iler, load from your trailer will
be transferred to your vehicl e. Consult this manual to
determine how this reduces the available cargo and luggage
load capacity of your vehicle.

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 15 lbs (7 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.

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.

■To estimate the tongue load
Excessive tongue load reduces front tire traction and steering control. Too little
tongue load can make the trailer unstable and cause it to sway.
You can estimate the tongue load by meas uring the trailer hitch height from the
ground in the following steps:
1. Park the vehicle on level ground.
2. Measure the distance between the ground and the bottom of the trailer hitch.
3. Connect the fully loaded trailer to the hitch.
4. Measure the distance between the ground and the bottom of the trailer hitch
again.
5. Subtract the second measurement from th e first measurement, then refer to the
following table.
If the difference becomes more than indicated in the table, distribute the load or
remove cargo as needed.

■How to weigh the trailer load s 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.

•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 ma nual 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 4WD 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 bra kes: 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.1Trailer brakes
The 4-pin gray connector is located under the left
side instrument panel.
