• Do not tow a trailer at all during the first 1,000 miles
(1 600 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
• Then, during the first 500 miles (800 km) that you
tow a trailer, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This
helps your engine and other parts of your 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 your vehicle’s parts.
Three important considerations have to do with weight:
• the weight of the trailer
• the weight of the trailer tongue
• and the total weight on your vehicle’s tires
Weight of the Trailer
How heavy can a trailer safely be? It should never
weigh more than 1,000 lbs (450 kg). These are total
maximum weights including the load. But even that can
be too heavy.
The STS-V is not rated or designed to tow any trailer.
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull
a trailer are all important. It can also depend on any
special equipment that you have on your 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.
