GMC 1993 Jimmy Owner's Manual page 231

Before you start, check the trailer hitch and platform, safety chains, electrical
connector, lights, tires and mirror adjustment.
I f the trailer has electric brakes,
start your vehicle and trailer moving and then apply the trailer brake controller
by hand to be sure the brakes are working. This lets you check your
electrical connection at the same time.

I f you have a rear-most
window
open and
you pull a
trailer
with your
vehicle,
carbon
monoxide
(GO)
could come into your vehicle. You
can't see
or
smell
CO.
It can cause
unconsciousness or
death (see
"Engine Exhaust'' in the, Index.) To maximize your safety when
towing a trailer:
*
Have your exhaust
system
inspected for Isaks and make
necessary repairs before starting on your trip.

Keep the reapmost windows
closed.

If exhaust does
cume
into your vehicle
through a
window in the
rear
or mother opening, drive with your front, main heating
or
cooling system
on
and with the fan
on
any speed. This will
bring fresh,
outside
air
into
your
vehicle. D o ' not use MAX N C
because it
only
recirciilates the air inside
your vehicle.
See
*'Comfort Controls" in the Index.

During your trip, check occasionally
to be sure that the load is secure, and
that the lights and any trailer brakes are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you would when
driving your vehicle without a trailer. This can help you avoid situations that
require heavy braking and sudden turns.
Passing
You'll need more passing distance up ahead when you're towing a trailer.
And, because you're
a
good deal longer, you'll need to go much farther
beyond the passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand. Then, to move the
trailer left, just move your hand to the left. To move the trailer to the right,
move your hand to the right. Always back up slowly and, if possible, have
I
someone guide you.
