WARNING: This page is about a different car, the 2017 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.

Disconnecting the ground cable from the battery automatically deletes the contents of certain electronic system memories (such as electric window lifter, time and date settings). After reconnecting the ground cable to the battery, these volatile memories must be reprogrammed and audio equipment decoded.
In some vehicles with ESP, the steering angle sensor must be recalibrated after disconnecting the battery - consider the service information!
Disconnect the battery from the on-board power supply before charging or rapid charging. Never start the vehicle by using a rapid charger.
Ensure the correct seating of the battery terminals.
Wiring harnesses and wiring troughs which are released or removed during repair work must be refastened in their original positions using genuine aftersales parts (cable ties, clips, wiring trough brackets, etc.).
During the removal / installation of the engine or the transmission, it must be ensured that all ground connections are correctly routed. Poor ground connections lead to malfunctions in the system and, in extreme cases, to the destruction of control units. Never connect and disconnect control unit or miscellaneous electronic component wiring harness plugs with the ignition switched on.
When mounting components in a vice, always use protective jaws made of soft metal.
Place removed components on clean surfaces only and cover with foil - never use lint-producing cloths. If repairs cannot be carried out immediately, seal open components or cover them carefully. Only install clean parts. Remove new parts from their packaging just right prior to installation.
Check all components for signs of wear and replace if necessary.
To prevent damage to toothed-belt fabric, ensure that toothed belt does not come into contact with coolant, oil, fuel, brake and clutch fluid and grease.
The components of the engine are sensitive to shock and must not be installed if damaged. This applies in particular to the throttle valve body as severe malfunctions may be result if damaged by being dropped.
