Unless other wise indicated, check these components in accordance with the Maintenance and Warranty Guide and according to your engine. Other wise, have them checked by a CITROËN dealer.
The battery does not require any maintenance. However, check that the terminals are clean and correctly tightened, particularly in summer and winter. When carrying out work on the battery, refer to the "Practical information" section for details of the precautions to be taken before disconnecting the battery and following its reconnection.
Refer to the Maintenance and Warranty Guide for details of the replacement inter vals for these components. Depending on the environment (e.g. dusty atmosphere) and the use of the vehicle (e.g. city driving), replace them twice as often if necessar y (refer to the "Engines" section).
