To close the rear doors, close the driver's side door first. Check to make sure both doors are completely closed. The rear doors have a check assembly to keep the doors from opening beyond 90 degrees. To fully open the rear doors, push in on the clip and lift the check assembly up off the mounting bracket. {CAUTION: It can be dangerous to drive with the rear glass open because carbon monoxide (CO) gas can come into your vehicle. You can not see or smell CO. It can cause unconsciousness and even death. If you must drive with the rear glass open or if electrical wiring or other cable connections must pass through the seal between the body and the rear glass: • Make sure all other windows are shut. • Turn the fan on your heating or cooling system to its highest speed and select the control setting that will force outside air into your vehicle. See Climate Control System on page 3-16. • If you have air outlets on or under the instrument panel, open them all the way. See Engine Exhaust on page 2-28. Do this on each door. Replace the check assemblies on the mounting brackets before closing the doors. 2-12
