5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated in
Step 4.
6.If your vehicle will be towing a trailer, the 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.
If your vehicle can tow a trailer, see“Towing a
Trailer” for important information on towing a
trailer, towing safety rules, and trailering tips.

Here are some important things to consider before
recreational vehicle towing:
.What's the towing capacity of the towing vehicle?
Be sure to read the tow vehicle manufacturer's
recommendations.
.How far will the vehicle be towed? Some vehicles
have restrictions on how far and how long they
can tow.
.Does the vehicle have the proper towing
equipment? See your dealer or trailering
professional for additional advice and equipment
recommendations.
.Is the vehicle ready to be towed? Just as preparing
the vehicle for a long trip, make sure the vehicle is
prepared to be towed. SeeBefore Leaving on a
Long Trip on page 5‑13.
Dinghy Towing
Notice: If the vehicle is towed with all four wheels
on the ground, the drivetrain components could be
damaged. The repairs would not be covered by the
vehicle warranty. Do not tow the vehicle with all
four wheels on the ground.
The vehicle was not designed to be towed with all
four wheels on the ground. Use a dolly if the vehicle
must be towed. See “Dolly Towing”later in this section
for more information.

Notice:Pulling a trailer improperly can damage the
vehicle and result in costly repairs not covered by
the vehicle warranty. To pull a trailer correctly,
follow the advice in this section and see your dealer
for important information about towing a trailer with
the vehicle.
The vehicle can tow a trailer if it is equipped with
the proper trailer towing equipment. To identify the
trailering capacity of the vehicle, read the information
in “Weight of the Trailer” that appears later in this
section. Trailering is different than just driving the
vehicle by itself. Trailering means changes in handling,
acceleration, braking, durability and fuel economy.
Successful, safe trailering takes correct equipment, and
it has to be used properly.
The following information has many time-tested,
important trailering tips and safety rules. Many of
these are important for the safety of the driver and the
passengers. So please read this section carefully before
pulling a trailer.
Load-pulling components such as the engine,
transmission, axles, wheel assemblies and tires are
forced to work harder against the drag of the added
weight. The engine is required to operate at relatively
higher speeds and under greater loads, generating
extra heat. The trailer also adds considerably to wind
resistance, increasing the pulling requirements.Pulling A Trailer
Here are some important points:
.There are many different laws, including speed
limit restrictions, having to do with trailering. Make
sure the rig will be legal, not only where you live
but also where you will be driving. A good source
for this information can be state or provincial
police.
.Do not tow a trailer at all during the
first 1,000 miles (1600 km) the new vehicle
is driven. The engine, transmission or other
parts could be damaged. The repairs would
not be covered by the vehicle's warranty.
.Then, during the first 500 miles (800 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps
the engine and other parts of the vehicle wear in at
the heavier loads.
.Vehicles can tow in D (Drive). Shift the
transmission to a lower gear if the transmission
shifts too often under heavy loads and/or hilly
conditions.
.Obey speed limit restrictions when towing a trailer.
Do not drive faster than the maximum posted
speed for trailers, or no more than 55 mph
(90 km/h), to save wear on the vehicle's parts.

.Do not tow a trailer when the outside temperature
is above 100°F (38°C).
.If the vehicle has the Side Blind Zone Alert (SBZA)
system and it doesn't seem to be working properly
while pulling a trailer, turn the system off. SeeSide
Blind Zone Alert (SBZA)
on page 3‑42for more
information.
Three important considerations have to do with weight:
.The weight of the trailer
.The weight of the trailer tongue
.The total weight on the vehicle's tires
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 lbs (454 kg). But
even that can be too heavy.
It depends on how the rig is used. For example,
speed, altitude, road grades, outside temperature and
how much the vehicle is used to pull a trailer are all
important. It can depend on any special equipment
on the vehicle, and the amount of tongue weight the
vehicle can carry. See “Weight of the Trailer Tongue”
later in this section for more information. Maximum trailer weight is calculated assuming only the
driver is in the tow vehicle and it has all the required
trailering equipment. The weight of additional optional
equipment, passengers and cargo in the tow vehicle
must be subtracted from the maximum trailer weight.
Ask your dealer for trailering information or advice,
or write us at our Customer Assistance Offices. See
Customer Assistance Offices
on page 8‑6for more
information.
Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight
to measure because it affects the total gross weight of
the vehicle. The Gross Vehicle Weight (GVW) includes
the curb weight of the vehicle, any cargo carried in it,
and the people who will be riding in the vehicle. If there
are a lot of options, equipment, passengers or cargo in
the vehicle, it will reduce the tongue weight the vehicle
can carry, which will also reduce the trailer weight the
vehicle can tow. If towing a trailer, the tongue load must
be added to the GVW because the vehicle will be
carrying that weight, too. See Loading the Vehicle
on
page 5‑18for more information about the vehicle's
maximum load capacity.
