Modern RVs come equipped with a carbon monoxide detector to detect unsafe levels of carbon monoxide. If the alarm sounds take the following steps:

• If you are driving, open all the windows until the driver can come to a safe place to stop.
• Once you are able to stop, shut off the engine, and the generator if running, and exit the vehicle.
• Allow the vehicle to ventilate, then search for the source of the carbon monoxide, such as generator exhaust.
• Do not re-enter the vehicle until you have determined that it is safe to do so.

When running the generator, it is best to keep the windows nearest to the generator exhaust closed, to prevent excess carbon monoxide from entering the cabin.

Like the smoke detector, the carbon monoxide detector will “chirp” when the 9-volt battery is low.

When you need to replace the battery, follow these steps:

• Remove the alarm by twisting the case in a counter-clockwise motion.
• Remove and discard the used battery.
• Install the new battery.
• Check to make sure that the battery is seated properly. You can test the alarm while it is off the mounting bracket by pushing the test button
• Reinstall the alarm by twisting the case in a clockwise motion.
• Re-test the alarm.
