User manual GMC SIERRA 1994

[. . . ] I 191 O w n e r ' sM a n u a l INTRODUCTION 1994 GMC Sierra Owner's Manual Welcome This manual was prepared to acquaint you with the operation and maintenance of your 1994 GMC Sierra and to provide important safety information. There is also a GMC Truck Warranty and Owner Assistance Information booklet. In some vehicles, there can be information manuals from other manufacturers like body builders or special equipment companies. We urge you to review all these publications carefully. [. . . ] Cross the safety chains under the tongue of the trailer so that the tongue will not drop to the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. Follow the manufacturer's recommendation for attaching safety chains. Always leavejust enough slack so you can turn with your rig. And, never allow safety chains to dragon the ground. Trailer Brakes If your trailer weighs more than 1, 000 pounds (450 kg) loaded, then it needs its own brakes - and they must be adequate. Be sure to read and follow the instructions for the trailer brakes so you'll be able to install, adjust and maintain them properly. Your trailer brake system can tap into your vehicle's hydraulic brake system, but consider the following: 0 Will the trailer brake system use more than 0. 02 cubic inch (0. 3 cc) of fluid from your vehicle's master cylinder?If it will, don't tap into your vehicle's brake system. Both braking systems won't work well, and you could even loseyour brakes altogether. Will the trailer brake parts take 3, 000 psi (20 650 kPa) of pressure?If not, the trailer brake system must not be used with your vehicle. 0 If everything checks outthis far, make the brake tap at the port on the master cylinder that sends the fluid to the rear brakes. But don't use copper tubing for this. if you do, it will bend and finally break off. 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 toknow 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 yourvehicle is by itself. 4-41 Before you start, checkthe 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. 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 tothe left, just move that hand to the left.
