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 dis-
play
when the anti-lock brakes or the Elec- tronic stability control are engaged - e.g.when a wheel loses grip on a slippery road
when speed-dependent power steeringwheel resistance is working at reducedpower – e.g. during cooling due to over-heating.
when, while parking, the parking sensorsdetect a vehicle or pedestrian in the vehi-cle's intended direction of travel behind orin front of the vehicle, the auto-brake func-tion will bring the vehicle to a standstill.
A message in the center display will explainwhy the parking sequence was cancelled.
CAUTION
Under certain circumstances, the function may not be able to find parking spaces –one reason may be that the sensors aredisrupted by external sound sources thatemit the same ultrasonic frequencies thatthe system works with. Examples of such sources include horns, wet tires on asphalt, pneumatic brakes,exhaust noise from motorcycles, etc.
NOTE
Dirt, ice and snow covering the sensors reduce their function and can make meas-urement impossible.
Driver responsibilityThe driver should keep in mind that the func- tion is a parking aid ‒
not an infallible fully
automatic system. The driver must always beprepared to take control and cancel a parkingsequence if necessary. There are a number of things to keep in mindwhen parking, including:
The driver is always responsible for deter-mining if the space suggested by the func-tion is suitable for parking.
Do not use the function when using snowchains or a temporary spare tire.
Do not use the function if there are anyobjects protruding from the vehicle.
Heavy rain or snowfall may inhibit PAP'sability to accurately measure a parkingspace.
While searching and measuring the park-ing space, the function may be unable todetect objects located far into the space.
PAP may not suggest parking spaces onnarrow streets if it does not detect suffi-cient space for maneuvering the vehicle.
Use approved tires 105
inflated to the cor-
rect tire pressure because this affects thefunction's ability to provide parking assis-tance.
The function is based on the way the vehi-cles are parked behind and in front of yourparking space. If they are, for example,parked too close to the curb, there is a riskthat your vehicle's tires or wheel rims

"Approved tires" refers to tires of the same type and make as the vehicle's original, factory-installed tires.

Brake functions
The vehicle's brakes are used to reduce speed or prevent the vehicle from rolling.
In addition to the wheel brakes and parking brakes, the vehicle is also equipped with anumber of automatic brake assist functions.These systems provide assistance by e.g. thedriver not needing to depress the brake pedalat a traffic light, when starting up a hill orwhen driving down a hill. Depending on how the vehicle is equipped, the following brake assist functions may beincluded:
Auto-hold brake function at a standstill(Auto Hold)
Hill Start Assist (Hill Start Assist)
Braking assist after a collision

Brakes
The brake pedal is used to apply the vehicle's regular brakes, which are part of the brakesystem.
The vehicle is equipped with two brake cir- cuits. If one brake circuit is damaged, thebrake pedal will go down further whendepressed. More pressure will then berequired from the driver for normal brakingeffect.
WARNING
The power brakes only work when the electric motor or combustion engine is run-ning.
If the brake pedal is used when the engine is switched off, greater pressure must be appliedto brake the vehicle. In very hilly areas or when driving with a heavy load, gear position B can be used to augment
the brakes with engine braking. Use the Off Road drive mode to increase the engine braking effect when driving on steepdowngrades at low speeds.
Anti-lock brakesThe vehicle is equipped with an Anti-lock Braking System (ABS 2
), which helps prevent
the wheels from locking and helps maintain steering control when braking. Vibrations may

Parking brake
The parking brake helps keep the vehicle sta- tionary by mechanically locking two wheels.
The parking brake controls are located in the tunnel console between the seats.
When the electric parking brake is being applied, a faint sound can be heard from thebrake's electric motor. This sound can also beheard during the automatic function check ofthe parking brake. If the vehicle is stationary when the parking brake is activated, it will only be applied to therear wheels. If it is activated while the vehicleis moving, the normal brakes will be used onall four wheels. Braking will be transferred toonly the rear wheels when the vehicle isalmost stopped.

Gear selector positions for automatic transmissions
With an automatic transmission, a suitable gear is selected automatically according tocurrent speed and power requirements.
Selecting gearsThe gear selector is a shift-by-wire selector, where shifting is done electronically instead ofmechanically. This makes shifting easier andthe gear positions more distinct.
Gear selector and gear selector positions overview.
Change gear position by pushing the spring- loaded gear selector forward or rearward, or tothe side for manual shifting.
Gear selector positions
Park - P
Gear selector and P position overview
Park is activated using the P button located
next to the gear selector. In P mode, the transmission is mechanically
locked.Select P when the vehicle is parked or when
starting the engine. The vehicle must be sta- tionary when Park is selected. To move to another gear from Park, the brake pedal must be depressed and the ignition inmode II.
When parking – apply the parking brake before shifting to Park.
WARNING
Always apply the parking brake when park- ing on an incline. Selecting a gear or put-ting the automatic transmission in P may
not be sufficient to keep the vehicle sta-tionary in all situations.
NOTE
The gear selector must be in position P in
order to lock the vehicle and set the alarm.
Help functions The system will automatically shift to P
if the ignition is switched off while
D or R
is selected.
if the driver unbuckles the seat belt and opens the driver's door while the vehicle isrunning with the gear selector in a gearother than
