Towing A Trailer - GMC 1993 Safari Owner's Manual

Will the trailer brake parts take
3,000 psi (20 650 kPa) of pressure? If

port on the master cylinder that sends fluid to the rear brakes. But don't

Use steel brake tubing.
Driving with a Trailer
Towing a trailer requires a certain amount of experience. Before setting out
for the open road, you'll want to get to know your rig. Acquaint yourself with
the feel of handling and braking with the added weight of the trailer. And
always keep in mind that the vehicle you are driving is now a good deal
longer and not nearly
so responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform, safety chains, electrical
connector, lights, tires and mirror adjustment. If 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.
If you have a rear-most window open and you pull a trailer with your
vehicle, carbon monoxide (CO) could come into your vehicle. You

Keep the rear-most windows closed.
If exhaust does come into your vehicle through a window in the
rear, or another 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. Do not use MAX N C
because it only recirculates 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.
