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. See Side
Blind Zone Alert (SBZA)
on page 3‑42
for 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

on page 8‑6

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 5‑18
for more information about the vehicle's
maximum load capacity.
