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.
• 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).
Three important considerations have to do with weight:
• the weight of the trailer,
• the weight of the trailer tongue
• and 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/retailer for trailering information or
advice, or write us at our Customer Assistance Offices.
