Perceived temperature
The climate control system regulates the climate in the passenger compartment based on per-ceived temperature, not actual temperature.
The selected passenger compartment tempera- ture is based on the physical perception of thecurrent ambient temperature, airflow speed,humidity, sunlight in the passenger compartment,etc. The system has a sunlight sensor that detects which side of the vehicle the sunlight is shiningon and adjusts the temperature accordingly. Thismeans that the temperature of the air coming outof the vents may be different for the left and rightsides, even if the temperature setting is the samefor both sides.

Start knob in the tunnel console.
WARNING
Before starting:
• Buckle your seat belt.
• Adjust the seat, steering wheel and mir- rors.
• Make sure you can fully depress thebrake pedal. The remote key is not physically used to start theignition because the vehicle is equipped with thekeyless Passive Start system. To start the vehicle:
1. The remote key must be inside the vehicle.
For vehicles with Passive Start, the key must be in the front section of the passengercompartment. With the optional keyless lock- ing/unlocking function *, the key can be any-
where in the vehicle.
2. Press and hold down the brake pedal 1
as far
as possible.
3. Turn the start knob clockwise and release. The control will automatically return to the original position.
WARNING
• Never use more than one inlay mat at a time on the driver's floor. If any other typeof floor mat is used, remove the originalmat from the driver's seat floor beforedriving. All types of mats must be securelyanchored in the attachment points in thefloor. Make sure the floor mat does notimpede the movement of the brake pedalor accelerator pedal in any way, as thiscould be a serious safety hazard.
• Volvo's floor mats are specially manufac-tured for your vehicle. They must be prop-erly secured in the attachment points inthe floor to help ensure they cannot slideand become trapped under the pedals.
The starter motor will crank until the enginestarts or until its overheating protection is trig-gered.

Leveling control * and suspension
The vehicle's leveling control system adjusts the suspension and shock absorbers automaticallyto help provide good comfort and control whiledriving. Leveling can also be controlled manuallyto facilitate loading or getting in and out of thevehicle.
Pneumatic suspension and shock absorbers
The system is adapted to the selected drive mode and vehicle speed. The pneumatic suspen-sion reduces the vehicle's ground clearance athigher speeds to reduce air resistance andincrease stability. The shock absorbers are nor-mally set to provide the best possible comfort and are adjusted continuously according to theroad surface and the vehicle's acceleration, brak-ing and cornering.
The instrument panel indicateswhen the suspension level isbeing adjusted.The level cannot be adjusted when any of the side doors or the tailgate is open.
ParkingWhen parking, make sure that there is adequatespace above and below the vehicle since ground clearance may vary depending on e.g. ambienttemperature, how the vehicle is loaded, if loadingmode is used, which drive mode is selected afterthe engine is started, etc. The level may also be adjusted a period after the vehicle is parked. This is to compensate for anyheight changes that may occur due to tempera-ture changes in the air springs when the vehiclecools.
TransportingWhen transporting the vehicle on a ferry, train ortruck, only secure (lash) the vehicle around thetires, not using any other parts of the chassis.Changes in the pneumatic suspension may occurduring transport, which could adversely affect thelashing and result in damage.
