Using the electrical outlets
The 12 V outlet can be used for devices intended for this such as MP3 players, coolersand cellular phones.
The ignition must be in at least mode I for the
outlets to supply current. The outlets will then be active as long as there is sufficient charge in thestart battery. If the engine is turned off and the vehicle is locked, the outlets will be deactivated. If theengine is turned off and the vehicle remainsunlocked, the sockets will remain active for up to7 minutes.
NOTE
Bear in mind that using the electrical outlets when the engine is off could cause the starterbattery to have too low of a charge level,which could limit other functionality. Accessories connected to the electrical out- lets can be activated even when the vehicleelectrical system is off or if preconditioning isused. For this reason, disconnect plugs whenthey are not in use to prevent the starter bat-tery from becoming discharged.
WARNING
• Do not use accessories with large or heavy plugs – they could damage the out-let or come loose while you are driving.
• Do not use accessories that could causedisruptions to e.g. the vehicle's radioreceiver or electrical system.
• Position the accessory so that there is norisk of it injuring the driver or passengersin the event of heavy braking or a colli-sion.
• Pay attention to connected accessoriesas they can generate heat that could burnpassengers or the interior.
Using 12 V outlets1. Remove the stopper (tunnel console) or fold
down the cover (trunk/cargo compartment)over the socket and plug in the device.
2. Unplug the device and put the stopper back in (tunnel console) or fold up the cover(trunk/cargo compartment) when the socketis not in use or left unattended.

Refilling coolant
Coolant helps keep the combustion engine at the right operating temperature. The heat trans-ferred from the engine to the coolant can beused to warm the passenger compartment.
When refilling coolant, follow the instructions on the package. Never fill the cooling system withonly water. The risk of freezing is increased withtoo low or too high amounts of coolant. If there is coolant under the vehicle, smoke from the cooling system, or if more than 2 liters (about2 quarts) of coolant has been added to the sys-tem, there could be something wrong with thecooling system and starting the vehicle coulddamage the engine. Call a tow truck and do notattempt to start the engine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. If coolantmust be filled, unscrew the expansion tankcap slowly to relieve overpressure.

CAUTION
Only a modern battery charger with controlled charge voltage should be used to charge thestarter battery and support battery. The rapidcharging function should not be used as thiscould damage the battery.
CAUTION
Failure to observe the following could cause the infotainment energy save mode to tempo-rarily stop working and/or a message in thedriver's display regarding the state of chargeof the starter battery may be temporarilyincorrect after an external starter battery orbattery charger has been connected:
• The negative battery terminal of the vehi- cle's starter battery must
never be used
to connect an external starter battery orbattery charger – only the vehicle's neg-
ative charging point should be used as
a grounding point.
NOTE
If the starter battery becomes discharged too many times, it will shorten its service life. The service life of the starter battery is affec- ted by several factors, such as driving condi-tions and climate. The starting capacity of thebattery reduces gradually over time. The bat-tery must therefore be recharged if the vehi-cle is not used or a long period of time or if itis only driven short distances. Severe cold fur-ther limits the starting capacity. To keep the starter battery in a good condi- tion, the vehicle should be driven at least15 minutes per week or the battery should beconnected to a battery charger with automatictrickle charging. A starter battery that is always kept fully charged has the maximum service life.
Location
The start battery is located in the trunk.
WARNING
If the starter battery is disconnected, the func- tion for automatic opening and closing mustbe reset to function correctly. A reset isrequired in order for the pinch protection towork.
CAUTION
On certain models, the battery is secured with a tensioning strap. Make sure that the ten-sioning strap is always securely tightened.
