Park Assist Pilot * limitations
Park Assist Pilot PAP 126
may not be able to
detect all conditions in all situations and func- tionality may therefore be limited.WARNING
• The PAP function is supplementary driver support intended to facilitate driving andhelp make it safer – it cannot handle allsituations in all traffic, weather and roadconditions.
• Pay particular attention to people andanimals near the vehicle.
• Bear in mind that the front end of thevehicle may swing out towards oncomingtraffic during the parking maneuver.
• Objects situated higher than the detec-tion area of the sensors are not includedwhen the parking maneuver is calculated,which could cause PAP to swing into theparking space too early. Such parkingspaces should be avoided for this reason.
• PAP is not a substitute for the driver'sattention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.
The driver should be aware of the following limi-tations for Park Assist Pilot:
The parking sequence is cancelledA parking sequence will be cancelled if:
• the driver moves the steering wheel
• the vehicle's speed exceeds 7 km/h (4 mph)
• the driver taps
Cancel in the center display
• when the anti-lock brakes or the Electronic stability control are engaged - e.g. when awheel loses grip on a slippery road
• when the power steering works at reduced power - e.g. during cooling due to overheat- ing (see section "Speed-dependent steeringforce").
A message in the center display will explain whythe parking sequence was cancelled.
CAUTION
Under certain circumstances, PAP may not be able to find parking spaces – one reason maybe that the sensors are disrupted by externalsound sources that emit the same ultrasonicfrequencies that the system works with. Examples of such sources include horns, wet tires on asphalt, pneumatic brakes, exhaustnoise from motorcycles, etc.

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 cargo com- partment
* can be used.
• The infotainment system can be used 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!

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.

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 4
to help reduce body roll when cornering.
The Start/Stop function is deactivated.

Driving with a trailer
There are a number of things to consider when towing a trailer, such as the towbar, the trailerand how the load is distributed in the trailer.
Load-carrying capacity is determined by the vehi- cle's curb weight. The total weight of all passen-gers and any installed accessories, e.g. towbar,reduces the vehicle's load-carrying capacity bythe corresponding amount. • Towbars used on the vehicle must be approved for the applicable use.
• Distribute the load on the trailer so that theweight on the towbar complies with thespecified maximum towball weight. Thetongue weight is calculated as part of thevehicle's payload.
• Increase the tire pressure to the recom-mended pressure for a full load.
• The engine is subjected to more load thanusual when towing a trailer.
• Towing a trailer affects the vehicle's han-dling, durability and driving economy.
• Do not drive with a heavy trailer when thevehicle is very new. Wait until the mileagehas reached at least 1000 km (620 miles).
• On long and steep downgrades, the vehicle'sbrakes are subjected to much more loadthan usual. When manually shifting, down-shift and adapt speed accordingly. •
Follow applicable regulations regarding per-mitted speed and weight.
• Drive slowly when towing a trailer up a longand steep incline.
• The maximum trailer weights given only applyto altitudes up to 1000 meters (3280 feet)above sea level. At higher altitudes, enginepower (and thus the vehicle's climbing ability)is decreased due to the reduced air density,and the maximum trailer weight must there-fore be reduced. The weight of the vehicleand trailer must be decreased by 10% foreach additional 1000 m (3280 feet) or partthereof.
• Avoid driving with a trailer on inclines of morethan 12%.
• Avoid overloading and other incorrect use.
• The trailer's brakes must be balanced withthe vehicle's brakes to help ensure safestops (follow applicable local regulations).
