Stopping hybrid battery charging To stop charging of the hybrid battery, unlock the vehicle, unplug the charging cable fromthe vehicle's charging socket and thenunplug the cable from the 120/240 V outlet(alternating current).
CAUTION
Before the charging cable is removed from the vehicle's charging socket, the vehiclemust be unlocked using the unlock buttonon the remote key. This must be done evenif the vehicle's doors are already unlocked.If the vehicle is not unlocked using theunlock button, the charging cable or sys-tem may be damaged.
NOTE
Always unlock the vehicle so that charging is cut off before the connection to the120/240 V outlet (AC, alternating current)is disconnected. Note that the chargingcable must be disconnected from the vehi-cle's charging socket before it is discon-nected from the 120/240 V outlet, partlyto prevent damage to the system and partyto prevent unintentional interruption ofcharging.
Unlock the vehicle with the remote key. Charging will stop.
Press the lock button on the charging cable's handle. The handle will bereleased/unlocked. Unplug the cable fromthe vehicle's charging socket and closethe charger door.
Unplug the cable from the 120/240 V out- let. Stow the charging cable in the storage compartment on the right side of thetrunk.
Charging cable automatically locksIf the charging cable cannot be removed fromthe charging socket, it will automatically lockinto place again after unlocking to maximizecharging and range and to enable precondi-tioning before driving. The charging cable canbe removed again if the vehicle is unlockedusing the remote key. For vehicles with Passive Entry *, the handle can be used to lock
and unlock.

Long-term storage of vehicles with hybrid batteries To help minimize degradation of the hybrid battery if the vehicle is not driven for a pro-longed period (longer than 1 month) thehybrid battery charge level should be kept atapprox. 25% according to the gauge in theinstrument panel.
Do as follows:
1. If the hybrid battery charge level is high,drive the vehicle until the charge level is approximately 25%. If the charge level islow, charge the battery until the level rea-ches approximately 25%. 2. If the vehicle is not driven for more than 6
months or the hybrid battery's chargelevel is noticeably below the 25% mark,charge the battery to about 25% to helpcompensate for the natural battery dis-charge that occurs in long-term storage.Regularly check the charge level using thegauge in the instrument display.
NOTE
Store the vehicle in as cool a location as possible to minimize battery aging duringlong-term storage. In the summer, park thevehicle indoors or in a shady location,whichever is cooler.

will go out and the selected theme will be dis- played to indicate that the electric motor isactivated. In some situations, such as in cold weather or if the hybrid battery's charge level is too low,the gasoline engine will start instead.
Error messagesIf the Vehicle key not found message is
shown in the instrument panel at start, place the remote key at the backup reader and thenmake a new start attempt.
Location of the backup reader in the tunnel console.
NOTE
When the remote key is placed in the backup reader, make sure that no othervehicle keys, metal objects or electronicdevices (e.g. cellular phones, tablets, lap-tops or chargers) are in the backup reader.Multiple vehicle keys close to each other inthe backup reader can disrupt their func-tionality.
If Vehicle start System check, wait is dis-
played in the instrument panel while attempt- ing to start the vehicle, wait until the messagedisappears and try again to start the vehicle.
CAUTION
If the engine has not responded after 3 attempts – wait for 3 minutes before star-ting a new attempt. Starting capabilityincreases if the starter battery is given timeto recover.
NOTE
The vehicle cannot be started if the hybrid battery is discharged.
WARNING
Never remove the remote control key from
the vehicle while driving.
WARNING
Always remove the remote key from the passenger compartment when youleave the vehicle and make sure theignition is in mode
0.
Always put the gear selector in
P and
apply the parking brake before leavingthe vehicle. Never leave the vehicleunsupervised while the engine is run-ning.
Always open the garage door fully andmake sure that ventilation is very goodbefore starting the engine in a garage.The exhaust fumes produced by thevehicle contain carbon monoxide,which is invisible and odorless but verytoxic.

CAUTION
When starting in cold weather, the automatic transmission may shift up atslightly higher engine speeds than nor-mal until the automatic transmissionfluid reaches normal operating tem-perature.
Do not race a cold engine immediatelyafter starting. This could prevent fluidsfrom properly lubricating vital compo-nents in the engine before it hasreached the proper operating tempera-ture.
The engine should be idling when thegear selector is moved. Never acceler-ate until the gear is fully engaged.Accelerating rapidly before a gear isproperly engaged could lead to harderwear of components.
To help prevent the transmission oilfrom overheating, select
P or N when
idling at a standstill for prolonged peri-ods of time.
NOTE
With a cold start, idling speed may be con- siderably higher than normal for certainengine types. This is done to get the emis-sions system up to normal operating tem-perature as quickly as possible, which min-imizes exhaust emissions and protects theenvironment.
