Cargo and luggage
Cargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacity) - (Total weight of occupants)
Steps for Determining Correct Load Limit 
(1) Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s
placard.
(2) Determine the combined weight of the driver and passengers that will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of cargo and lug- gage load capacity.
For example, if the “ XXX” amount equals 1400 lbs. and there will be
five 150 lb passengers in your v ehicle, the amount of available
cargo and luggage load capacity is 650 lbs. (1400 - 750 (5 150) =
650 lbs.)
(5) Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight ma y not safely exceed the available
cargo and luggage load capacity calculated in Step 4.
(6) If your vehicle will be towing a tr ailer, load from your trailer will be
transferred to your vehicle. Consult this manual to determine how
this reduces the available cargo and luggage load capacity of your
vehicle. ( P. 594)

WARNING
■Trailer towing precautions
To tow a trailer safely, use extreme care and drive the vehicle in accordance
with the trailer’s characteristics and operating conditions. Failure to do so
could cause an accident resulting in death or serious injury. Vehicle stability
and braking performance are affected by trailer stability, brake setting and
performance, and the hitch. Your vehi cle will handle differently when towing
a trailer.
■ To avoid accident or injury
● Do not exceed the TWR, unbraked TWR, GCWR, GVWR or GAWR.
● If the gross trailer weight is over 2000 lb. (907 kg), a sway control device
with sufficient capacity is required.
● Adjust the tongue weight within the appropriate range. Place heavier loads
as close to the trailer axle as possible.
● Do not exceed 65 mph (104 km/h), the posted towing speed limit or the
speed limit for your trailer as set forth in your trailer owner’s manual,
whichever is lowest. Slow down sufficiently before making a turn, in cross-
winds, on wet or slippery surface, etc. to help avoid an accident. If you
experience a vehicle-trailer instability from reducing a certain speed, slow
down and make sure you keep your vehicle speed under the speed of
which you experience the instability.
● Do not make jerky, abrupt or sharp turns.
● Do not apply the brakes suddenly as you may skid, resulting in jackknifing
and loss of vehicle control. This is especially true on wet or slippery sur-
faces.
● Do not exceed the trailer hitch assembly weight, gross vehicle weight,
gross axle weight and trailer tongue weight capacities.
