Driving with a Trailer CAUTION: (Continued) {CAUTION: 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 cannot see or smell CO. It can cause unconsciousness or death. See Engine Exhaust on page 2-42. To maximize your safety when towing a trailer: • Have your exhaust system inspected for leaks, and make necessary repairs before starting on your trip. CAUTION: (Continued) • 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 the climate control setting for maximum air because it only recirculates the air inside your vehicle. See Climate Control System on page 3-26. 4-46
