9-50 Driving and Operating
. Obey speed limit restrictions
when towing a trailer.
. The vehicle is designed
primarily as a passenger and
load carrying vehicle. If a trailer
is towed, the vehicle will require
more frequent maintenance due
to the additional load.
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.
Tow/Haul Mode
Tow/Haul assists when pulling a
heavy trailer or a large or heavy
load. The purpose of the Tow/Haul
mode is to:
. Reduce the frequency and
improve the predictability of
transmission shifts.
. Provide the same solid shift feel
as when the vehicle is unloaded.
. Improve control of vehicle speed
while requiring less throttle pedal
activity.
. Increase the charging system
voltage to assist in recharging
a battery installed in a trailer.
