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. See Side
Blind Zone Alert (SBZA) on page 3‑43 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.
