•Vehicles with automatic
transmissions can tow in D (Drive)
but M (Manual Mode) is
recommended. See “Manual
Mode” inAutomatic Transmission
on page 8-26for more
information. Use a lower gear if
the transmission shifts too often.
For vehicles with a manual
transmission, it is better not
to use the highest gear.
•Use the cruise control when
towing.
•Obey speed limit restrictions.
Do not drive faster than the
maximum posted speed for
trailers, or no more than 90 km/h
(55 mph), to reduce wear on the
vehicle.
Driving with a Trailer
Towing a trailer requires experience.
Get familiar with handling and
braking with the added trailer weight.
The vehicle is now longer and not as
responsive as the vehicle is by itself.
Check all trailer hitch parts and
attachments, safety chains, electrical
connectors, lamps, tires and mirror
adjustments. If the trailer has electric
brakes, start the vehicle and trailer
moving and then apply the trailer
brake controller by hand to be sure
the brakes are working.
During the trip, check regularly to
be sure that the load is secure, and
the lamps and trailer brakes are
working properly.
Towing with a Stability
Control System
When towing, the sound of the
stability control system might be
heard. The system is reacting to the
vehicle movement caused by the
trailer, which mainly occurs during
cornering. This is normal when
towing heavier trailers.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.
This can help to avoid situations that
require heavy braking and sudden
turns.
Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
much farther beyond the passed
vehicle before returning to the lane.
