CHECKING THE HIGH VOLTAGE BATTERY COOLANT LEVEL

CAUTION

The vehicle should be checked by a retailer/authorized repairer if the coolant level drops below the minimum mark. The high voltage battery coolant level should only be topped up by a trained vehicle technician. Running the vehicle with a low coolant level, or no coolant, causes serious damage.

The high voltage battery coolant level should be checked at least weekly. The level should be checked more frequently in high mileage or arduous operating conditions.

Always check the coolant level when the system is cold and the vehicle's electrical system is switched off.

To check the high voltage battery coolant level:

  1. Remove the relevant under-hood covers. See FLUID FILLER LOCATIONS and UNDER-HOOD COVERS REMOVAL.

  2. Check the high voltage battery coolant reservoir level. Keep the coolant system level at the MAX indicator mark on the expansion tank to achieve the optimum benefit of the high voltage battery cooling system. Make sure the coolant level does not fall below the MIN indicator mark on the expansion tank.

NOTES

If the coolant level has dropped suddenly, or by a large amount, arrange for the vehicle to be examined by qualified personnel. Consult a retailer/authorized repairer as soon as possible.
