Trunk Lid Tie Down CAUTION: (Continued) If you ever need to drive with your trunk lid open, then: D Make sure all windows, the rear seat pass-through and sunroof are closed. D Turn the fan on your heating and cooling system to its highest speed, with the setting on VENT. This forces fresh outside air into your vehicle. D Open all air ducts on the instrument panel. Don't use the trunk lid tie down if you are towing a trailer because of the danger of CO. CAUTION: Driving with the trunk lid open can allow dangerous CO (carbon monoxide) gas to come into your vehicle. You can't see or smell CO. It can cause unconsciousness and even death. CAUTION: (Continued) 2-13
