Battery, disconnecting
Note before disconnecting battery cables
The SRS (supplemental restraint system) is active for a certain time after the power is cut. Therefore wait three minutes before starting work.
- If the malfunction indicator light in the combined instrument panel is illuminated, the diagnostic trouble codes for the management system must first be read out and remedied before battery power is cut off.
- The ignition should be off for at least five minutes before the battery is disconnected from the car to allow the control modules time to store information.
- If the vehicle is equipped with remote heating, the personal code is reset to the factory value (1234) if the battery is disconnected or is discharged.
Always disconnect the negative battery cable before disconnecting any positive cables.
Note before connecting battery cables
Ensure that no live objects that can short-circuit the battery are under the battery's protective cover.
The key must be in position 2. No one must be in the car when the battery is connected. This is a safety precaution in case an airbag module activates when the power is connected.
