Preconditioning *
Preconditioning is a climate function that, if possible, attempts to achieve a comfortabletemperature in the passenger compartmentbefore driving.
Preconditioning can be started immediately or started at a preset time using a timer. In warm weather, the ventilation system cools the passenger compartment by blowing air infrom outside. The function cannot heat thepassenger compartment.
NOTE
During preconditioning of the passenger compartment, the vehicle works to reach acomfortable temperature and not the tem-perature set in the climate system.

Climate comfort retaining function *
The climate in the passenger compartment can be maintained when the vehicle isparked, e.g. if the engine is turned off but thedriver or passengers remain in the vehicle.
This function can only be direct-started. The function utilizes several of the vehicle's systems:
Residual heat from the engine is used tohelp heat the passenger compartment to acomfortable temperature.
In warm weather, the ventilation systemcools the passenger compartment byblowing air in from outside.
NOTE
Climate comfort maintenance will be deac- tivated if the vehicle is locked from the out-side in order to avoid using residual engineheat unnecessarily. This function isintended to be used to maintain climatecomfort when the driver or a passengerremains in the vehicle after the engine isturned off.

Battery drain
The electrical functions in the vehicle drain the battery to varying degrees. Avoid usingignition mode II when the engine is switched
off. Use ignition mode I instead, as this uses
less electrical current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical currentwhen the engine is turned off. Examples ofsuch functions are: blower
headlights
windshield wipers
audio system (especially at high volume).
If the starter battery voltage is low, a message is shown in the driver display. The vehicle'senergy-saving function will then turn off orreduce certain functions, such as the blowerand/or the audio system.
–Charge the battery by starting the engine and let it run for at least 15 minutes (driv-ing charges the battery faster than lettingthe engine idle).
