Installed on Vehicles with High Voltage Systems (Hybrid Vehicles) 

For all procedures on vehicles with a high-voltage system, pay attention to the additional warnings for these vehicles. Refer to SAFETY PRECAUTIONS WHEN WORKING ON VEHICLES WITH HIGH-VOLTAGE SYSTEM .

For the following procedures work near the high-voltage system components is necessary, "Safety Precautions when Working near High-Voltage Components". Refer to SAFETY PRECAUTIONS WHEN WORKING NEAR HIGH-VOLTAGE COMPONENTS .

Working on a high voltage system when activated or with the ignition turned on

-- To minimize the number of automatic motor starts during the testing and measuring procedures while the ready mode is active, charge the vehicle batteries in battery support mode with the Battery Charger: VAS5904  , for example. Refer to BATTERY, CHARGING and SAFETY PRECAUTIONS WHEN WORKING ON THE HIGH-VOLTAGE SYSTEM .

-- Move the selector level into position "P", activate the parking brake and arrange the necessary tools for testing and measuring procedures that require the ready mode to be active or that require the ignition to be on, so that they cannot come into contact with the turning components in the engine and so that they are not in the vicinity of the turning components of a running engine.

NOTE:

Also move the selector lever into position "P" and activate the parking brake for testing and measuring procedures which require the ignition to be on, but do not require the ready mode to be active.

The ready mode is displayed in the Instrument Cluster Control Module -J285- above the "powermeter". Refer to Owner's Manual.

Activate and deactivate the ready mode. Refer to Owner's Manual (consult the display in the Instrument Cluster Control Module -J285-).

-- On vehicles with a high-voltage system, switch off (deactivate) the "auxiliary climate control" function. Refer to the Owner's Manual and Infotainment/MMI Operating Manual.
