Trailer Brakes If your trailerweighs more than 1,000 Ibs. (450 kg) loaded, thenit needs itsown brakes -- and they must be adequate. Be sure toread 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 the vehicle's hydraulic brake system onlyif: The trailer parts can withstand 3,000 psi (20 650 kPa) of pressure. The trailer's brake system will use less than 0.02 cubic inch(0.3 cc) of fluid fromyour vehicle's master cylinder. Otherwise, both braking systems won't work well. You could even lose your brakes. If everything checks out this 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 this. for If you do, it will bend and finally break off. Use steel brake tubing. Driving with a Trailer If you have a rear-most window openand you pull a trailer with your vehicle, carbon monoxide (CO) could come into your vehicle. You can't see or smell CO. It can cause unconsciousness or death. (See "Engine Exhaust" in theIndex.) To maximize your safety when towinga trailer: 0 Have your exhaust system inspected for leaks, and make necessary repairs before starting on your trip. 0 Keep the rear-most windows closed. 0 If exhaust does come into your vehicle through a window in the rear oranother opening, drive with your front, main heating or cooling systemon and with the fan on any speed. This will bring fresh, outside air into your vehicle. Do not use the recirculation button or MAX because it only recirculates the air inside your vehicle. (See "Comfort Controls" in the Index.) 4-50
