Parking climate
*
The climate of the car's passenger compartment can be preconditioned or maintained while thecar is parked.
Preconditioning and climate comfort retention are con- trolled from the Parking climate tab in the centre dis-
play's climate view.
PreconditioningPreconditioning of the car before driving reduces wear and energy needs during a journey. Preconditioning can use direct start or be set viathe timer. The function utilises several systems in different cases: •
The parking heater
*, in a cold climate, warms
up both the passenger compartment and the engine.
• The ventilation, in a hot climate, cools thepassenger compartment to the current outertemperature.
NOTE
During preconditioning of the passenger compartment, the car works to reach comforttemperature and not the temperature set inthe climate control system.
Climate comfort retentionThe climate in the car's passenger compartment can be maintained while the car is parked, e.g. ifthe engine needs to be switched off but thedriver or passenger(s) wants to remain in the carand maintain the level of climate comfort. Starting climate comfort retention is only possible via direct start.

Speed-dependent steering force Speed related power steering causes the steer- ing wheel force to increase with the speed of thecar in order to give the driver enhanced sensitiv-ity.
On motorways the steering feels firmer. When parking and at low speed steering is light andrequires only a slight effort.
NOTE
In certain situations the power steering may become too hot and then needs to be tempo-rarily cooled - during this time the powersteering operates with reduced power andturning the steering wheel may then be per-ceived to be slightly heavier. In parallel with the temporarily reduced steer- ing assistance, the driver display shows amessage.
Change the steering force level *To select the steering force level, go to the "Drive modes" section and see the description at thealternative INDIVIDUAL under the heading"Selectable drive modes". For the car models without a drive mode control with its INDIVIDUAL option, the selection ofsteering force is instead made via the centre dis-play's top view and the following search path:

Roll Stability Control Roll Stability Control (RSC) is a stabiliser sys- tem that minimises the risk of overturning, forexample during sudden evasive manoeuvres or ifthe car skids.
The RSC system registers if and how much the car's lateral inclination changes. This informationis used to calculate the risk of the car overturn-ing. If the car is at risk, its electronic stability con-trol system engages, the engine torque isreduced and one or more wheels are braked untilthe car has regained its stability.
WARNING
Under normal driving conditions, the RSC sys- tem improves the car's road safety, but thismust not be taken as a reason to increasespeed. Always follow the normal precautionsfor safe driving.
