Ignition modes
The vehicle's ignition can be put in various modes (levels) to make different functions availa-ble.
To enable the use of a limited number of func- tions when the engine is not running, the ignition can be put in one of three different levels: 0, I
and II. These levels are referred to as "ignition
modes" in the Owner's Manual. The following table shows which functions are available in each ignition mode:
ModeFunctions
0 •The odometer, clock and tem- perature gauge are illuminated A
.
• The power seats
* can be
adjusted.
• The power windows can be used.
• The center display is activatedand can be used A
.
• The 12 V outlet in the trunk
* can
be used.
• The infotainment system can beused A
.
In this ignition mode, the functions are available for a limited time and then switch off automatically.
I •The panoramic roof, power win-dows, 12 V outlet in passengercompartment, Bluetooth, naviga-tion, phone, blower and wind-shield wipers can be used.
• The power seats can be adjusted.
• The 12 V outlet in the cargo com-partment can be used.
Electrical current will be takenfrom the battery in this ignitionmode.ModeFunctions
II •The headlights illuminate.
• Warning/indicator lights illumi- nate for 5 seconds.
• A number of other systems areactivated. However, seat and rearwindow heating can only be acti-vated when the engine is running.
This ignition mode uses a lot ofcurrent from the battery andshould be avoided whenever pos-sible!
A Also activated when the door is opened.

Brakes The brake pedal is used to apply the vehicle's regular brakes, which are part of the brake sys-tem.
The vehicle is equipped with two brake circuits. If one brake circuit is damaged, the brake pedal willgo down further when depressed. More pressurewill then be required from the driver for normalbraking effect. The driver's pressure on the brake pedal is enhanced by a power braking function.
WARNING
Power braking only functions if the engine is running.
If the brake pedal is used when the engine is turned off, the pedal will feel stiffer than usualand greater pressure must be applied to brakethe vehicle. In very hilly areas or when driving with a heavy load, manual gear shifting can be used to aug-ment the brakes with engine braking. Enginebraking is most effective if the same gear is usedboth uphill and downhill.
Anti-lock brakesThe vehicle is equipped with an Anti-lock BrakingSystem (ABS), which can help prevent thewheels from locking and help maintain steeringcontrol when braking. Vibrations may be felt from the brake pedal when ABS is operating, which isnormal. After the vehicle is started, a brief test of the ABS system is automatically performed when thedriver releases the brake pedal. An additionalautomatic test of the system may be performedwhen the vehicle is traveling at a low speed. Dur-ing the test, the brake pedal may feel as though itis pulsating.

All Wheel Drive (AWD)
*
All-wheel drive, All Wheel Drive (AWD), also called four-wheel drive, means that power is dis-tributed to all four wheels, which improves trac-tion.
To achieve the best traction, power is automati- cally directed to the wheels that have the bestgrip. The system continuously calculates theneed for torque to the rear wheels, and canimmediately redistribute up to half of the engine'storque to the rear wheels. All-wheel drive also has a stabilizing effect at higher speeds. In normal driving conditions, mostof the engine's power is directed to the frontwheels. When the vehicle is stationary, all-wheeldrive is always activated in preparation for maxi-mum traction during acceleration. All-wheel drive reacts differently depending on which drive mode * is selected.

Drive modes
*
Drive modes affect the vehicle's driving charac- teristics in different ways to enhance and sim-plify the driving experience in certain types of sit-uations.
Drive modes enable easy access to the vehicle's many functions and settings in different drivingsituations. The following systems are adapted tohelp optimize driving characteristics in each drivemode: • Steering
• Engine/transmission/all-wheel drive
*
• Brakes
• Shock absorbers
• Instrument panel
• Start/Stop function
• Climate control settings
Select the drive mode that is best suited to the current driving conditions. Keep in mind that notall drive modes are available in all situations.
Available drive modes
COMFORT
• This is the vehicle's default mode.
When the engine is started, the vehicle will be in Comfort mode and the Start/Stop function will beactivated. This setting offers driving comfort, lightsteering and soft suspension.

ECO
• Adapt the vehicle for more fuel-efficient and eco-friendly driving with Eco mode.
In this mode, the Start/Stop function is activatedand certain climate settings are reduced. The instrument panel has an ECO gauge to facili- tate fuel-efficient driving.
DYNAMIC
• Dynamic mode is designed to provide sport- ier driving characteristics and a faster accel-eration response.
Gear shifting will be faster and more distinct andthe transmission will prioritize gears with a highertraction force. Steering response is faster and suspension is stiffer 3
to help reduce body roll when cornering.
The Start/Stop function is deactivated.
INDIVIDUAL
• Customizes drive mode to personal preferen- ces.
Select one of the drive modes as a basis andadjust the settings to achieve your preferred driv- ing characteristics. These settings will be stored in your driver profile. Individual drive mode is only available if it has been activated in the center display.Settings view 4

Selecting sub-channels
To listen to a station's sub-channel(s), tap the station on the screen or press the forward/backarrow keys on the right-side steering wheel key-pad or below the screen. Sub-channels can also be saved as radio favor- ites. If you tap a sub-channel favorite, it may take up to 6 seconds before the channel becomes audi-
ble. If you tap a station while you are out of digital range of the transmitter,
No reception will be
displayed.

HD Radio™ limitations
Limitations
• Main channel vs. sub-channels (FM only)
:
The main channel is the only channel that can receive in hybrid mode (both digital andanalog). If a frequency has sub-channels,they are broadcast in digital mode only. Themain FM channel will be displayed as, forexample, "WRIF-FM HD1". The sub-FMchannels will be displayed as"WRIF-FMHD2", "WRIF-FM HD3", etc.
• Reception coverage area
: Due to current
IBOC transmitter power limitations, thereception coverage area in digital mode issomewhat more limited than the station'sanalog coverage area. Be aware that, like allradio transmission technology, terrain, time ofday, vegetation and buildings can have apositive or negative effect on radio reception.
• Analog to digital/digital to analog blend-ing
: Analog to digital blending will occur as
the signal strength reaches a preset thresh-old in the receiver. This will be noticeable infringe areas (areas with weak reception) andis normal.
NOTE
There may be a noticeable difference in sound quality when a change from analogueto digital or digital to analogue occurs, suchas:
• Volume increase or decrease
• Equalizer settings, i.e., Bass/ Midrange/Treble cut or boost
• Time alignment (Digital program materialin extreme cases can be as much as 8seconds behind the analogue). This willnoticeable as a "stuttering" effect.
The above items are dependant on thebroadcaster's equipment settings and donot indicate a fault in the vehicle's radioreceiver or antenna systems .
