Battery drain
Your vehicle's electrical functions drain the bat-tery to varying extents.
Avoid using ignition mode II as much as posssi-ble, or electrical functions that require a greatdeal of electrical current when the engine is notrunning.
Using ignition mode I whenever possible con-sumes less electrical current.
Functions that require a great deal of electricalcurrent include:
•the climate system blower
•headlights
•wipers
•infotainment system (especially at high vol-ume).
If the battery's charge level is low, a text messagewill appear in the instrument panel. The vehicle'senergy-saving function will then turn off orreduce certain functions that are currently con-suming electrical current.
If the battery needs to be recharged, start theengine and let it idle for at least 15 minutes ordrive the vehicle (driving charges the batteryfaster than letting the engine idle).

NOTE
After a cold start, idle speed may be noticea-bly higher than normal for a short period. Thisis done to help bring components in theemission control system to their normal oper-ating temperature as quickly as possible,which enables them to control emissions andhelp reduce the vehicle's impact on the envi-ronment.
CAUTION
•When starting in cold weather, the auto-matic transmission may shift up at slightlyhigher engine speeds than normal untilthe automatic transmission fluid reachesnormal operating temperature.
•Do not race a cold engine immediatelyafter starting. Oil flow may not reachsome lubrication points fast enough toprevent engine damage.
•The engine should be idling when youmove the gear selector. Never accelerateuntil after you feel the transmissionengage. Accelerating immediately afterselecting a gear will cause harsh engage-ment and premature transmission wear.
•Selecting P or N when idling at a stand-still for prolonged periods of time will helpprevent overheating of the automatictransmission fluid.
