19PP UPDATE
Replacing Thermostat– (NVLW)
Safety Precautions When Working ON the High-voltage System (Q5 hybrid only)
DANGER
Extremely dangerous due to high voltage.
•
The high-voltage system is under heavy voltage. Severe bodily injury or death by electrocution or electric
arcs is possible.
•
When working on the high-voltage system the high-voltage system must be de-energized.
•
When performing procedures that do not directly affect the high-voltage system, in some cases it is still
necessary to de-energize the high-voltage system.
•
Pay attention when the high-voltage system must be de-energized. Refer to the Repair Manual
•
Have an Audi high-voltage technician or an Audi high-voltage expert de-energize the high-voltage system.
The electric and magnetic fields are extremely dangerous.
•
There are electric and magnetic fields on the high-voltage system. Death or serious injury are possible due
to malfunction of active implants (for example cardiac pacemakers, insulin pumps).
•
Persons with active implants may not perform procedures on the high-voltage system.
WARNING
Risk of injury - motor may start unexpectedly
It is difficult to determine whether the drive system of an electric vehicle or hybrid vehicle is active. Moving parts can
trap or draw in parts of the body.
CAUTION
Risk of damage to high-voltage wiring
•
Incorrect handling may result in damage to the insulation of high-voltage wires or high-voltage connectors.
•
Do not support yourself on high-voltage cables or connectors.
•
Never prop tools against high-voltage wiring or high-voltage connectors.
•
Never bend or kink high-voltage wiring.
•
Observe the coding of the high-voltage connectors when joining them up.

Safety Precautions When Working NEAR the High-voltage System (Q5 hybrid only)
DANGER
Extremely dangerous due to high voltage.
•
The voltage levels in the high-voltage system constitute a safety hazard. Danger of severe or fatal injuries
from electric shock if high-voltage components or high-voltage wiring are damaged.
•
Carry out a visual check of high-voltage components and high-voltage wiring.
•
Never use cutting/forming tools or other sharp-edged implements.
•
Never perform work using welding, brazing, thermal bonding or hot air in the area of high-voltage
components and high-voltage cables.
