TRAILER SAFETY GUIDELINES

INOPERABLE BRAKES, LIGHTS OR MIRRORS

Be sure that the brakes and all of the lights on your trailer 

are functioning properly before towing your trailer. Check 

the trailer taillights by turning on your tow vehicle headlights.  

Check the trailer brake lights by having someone step on 

the tow vehicle brake pedal while you look at the trailer 

lights. Do the same thing to check the turn signal lights. 

See Trailer Wiring Diagram section in this manual.
Standard mirrors usually do not provide adequate visibility 

for viewing traffi c to the sides and rear of a towed trailer.  

You must provide mirrors that allow you to safely observe 

approaching traffi c.

TRAILER TOWING TIPS

Driving a vehicle with a trailer in tow is vastly different 

from driving the same vehicle without a trailer in tow.  

Acceleration, maneuverability and braking are all 

diminished with a trailer in tow.
It takes longer to get up to speed, you need more room to 

turn and pass, and more distance to stop when towing a 

trailer. You will need to spend time adjusting to the different 

feel and maneuverability of the tow vehicle with a loaded 

trailer.
Because of the signifi cant differences in all aspects of 

maneuverability when towing a trailer, the hazards and risks 

of injury are also much greater than when driving without 

a trailer. You are responsible for keeping your vehicle and 

trailer in control, and for all the damage that is caused if 

you lose control of your vehicle and trailer.
As you did when learning to drive an automobile, fi nd 

an open area with little or no traffi c for your fi rst practice 

trailering. Of course, before you start towing the trailer, you 

must follow all of the instructions for inspection, testing, 

loading and coupling. Also, before you start towing, adjust 

the mirrors so you can see the trailer as well as the area 

to the rear of it.

  WARNING

Improper electrical connection between the tow vehicle 

and the trailer will result in inoperable lights and can 

lead to collision.
Before each tow, check that the tail lights, brake lights 

and turn signals work.

Drive slowly at fi rst, 5 mph or so, and turn the wheel to 

get the feel of how the tow vehicle and trailer combination 

responds. Next, make some right and left hand turns. Watch 

in your side mirrors to see how the trailer follows the tow 

vehicle. Turning with a trailer attached requires more room.
Stop the rig a few times from speeds no greater than 

10 mph. If your trailer is equipped with brakes, try using 

different combinations of trailer brake and tow vehicle brake.  

Note the effect that the trailer brakes have when they are 

the only brakes used. When properly adjusted, the trailer 

brakes will come on just before the tow vehicle brakes.
It will take practice to learn how to back up a tow vehicle 

with a trailer attached. Take it slow. Before backing up, get 

out of the tow vehicle and look behind the trailer to make 

sure that there are no obstacles.
Some drivers place their hands at the bottom of the steering 

wheel, and while the tow vehicle is in reverse, “think” of the 

hands as being on the top of the wheel. When the hands 

move to the right (counterclockwise, as you would do to 

turn the tow vehicle to the left when moving forward), the 

rear of the trailer moves to the right. Conversely, rotating 

the steering wheel clockwise with your hands at the bottom 

of the wheel will move the rear of the trailer to the left while 

backing up.
If you are towing a bumper hitch rig, be careful not to allow 

the trailer to turn too much because it will hit the rear of the 

tow vehicle. To straighten the rig, either pull forward or turn 

the steering wheel in the opposite direction.

TRAILER VIN TAG

Figure A below is a sample of the Vehicle Identifi cation 

Number (VIN) Tag which is typically located on the left front 

of the trailer. See Figure B for location.

Figure A. Vehicle VIN Tag

  CAUTION

For Hydraulic Brake Models 

ALWAYS

 ensure that when 

backing up it is done in a slow, straight, and steady 

manner to safeguard the brakes from locking up.
