Cautions on chassis dynamometer use

When inspecting and servicing the powertrain on the dynamometer or speedometer tester, pay attention to the following:

NOTE:

If the engine cannot be stopped using the push button start, perform an emergency engine stop operation. (See Cautions for vehicles with Mazda Radar Cruise Control (MRCC) system/Smart Brake Support (SBS) system/Smart City Brake Support (SCBS) system/Distance Recognition Support System (DRSS).)
- Place a fan, preferably a vehicle-speed proportional type, in front of the vehicle.
- Make sure the vehicle is in a facility with an exhaust gas ventilation system.
- Keep the rear bumper cool by placing a cooling fan near the exhaust pipe so that the rear bumper does not get deformed by the heat from the exhaust.
- Keep the area around the vehicle uncluttered so that heat does not build up.
- Watch the water temperature gauge and do not overheat the engine.
- Avoid added load to the engine and maintain normal driving conditions as much as possible.
