Safety Precautions When Working On Vehicles With Parking/Auxiliary Heater
The parking/auxiliary heater poses a risk of fire and explosion
In areas that are subject to fire and explosion, a spark or the high temperature of the parking/auxiliary heater can ignite a fire or cause an explosion. It is possible to be burned.
-- In areas that are subject to fire and explosion, switch off the parking/auxiliary heater.
There is a risk of being poisoned by the exhaust fumes
The parking/auxiliary heater produces toxic exhaust fumes. Injury to the respiratory system and poisoning are possible.
-- Only switch on the parking/auxiliary heater in closed areas with an exhaust extracting system.
-- Switch off the parking/auxiliary heater in closed areas with no exhaust extracting system.
Starting the engine may cause damage.
When fuel system components and parking/auxiliary heater coolant circuit components are removed or open, then the parking/auxiliary heater may become damaged.
-- Never start the engine when these system components are removed or opened.
Air in the fuel supply causes malfunctions
After working on the fuel tank or the fuel delivery unit, the metering pump draws in air and sends the air to the parking/auxiliary heater. Air in the parking/auxiliary heater fuel supply may cause parking/auxiliary heater malfunctions.
-- Fill the fuel extraction line with fuel.
There is a risk of accident and injury when the parking/auxiliary heater timer is activated.
For vehicles with an activated timer for the parking/auxiliary heater, the parking/auxiliary heater can turn on unintentionally. Being poisoned by exhaust fumes and being burned by hot parking/auxiliary heater components is possible, along with the risk of high temperatures causing fires and explosions.
-- Deactivate the timer for the parking/auxiliary heater.
