Trailer Towing
When towing at high elevation on
steep uphill grades, consider the
following:
Engine coolant at higher elevation
will boil at a lower temperature than
at or near sea level. If the engine is
turned off immediately after towing
at high elevation on steep uphill
grades, the vehicle may show signs
similar to engine overheating. To
avoid this, let the engine run while
parked (preferably on level ground)
with the transmission in P (Park)

least five minutes before turning the
engine off. If the overheat warning

All axles of the trailer must be
equipped with brakes adequate for
the intended use. Trailer braking
equipment conforming to Canadian
