Cross Traffic Alert *
CTA 82
is a supplementary driver support system
to BLIS 83
that is intended to help the driver
detect vehicles crossing behind the vehicle while backing up.
CTA overview.
CTA supplements BLIS by detecting traffic cross- ing from the side, e.g. when backing out of aparking space. CTA is primarily designed to detect vehicles, but in certain cases can also detect pedestrians orsmaller objects such as bicycles. CTA is only active when the vehicle is moving backward or if reverse gear is engaged. If CTA detects that something is approachingyour vehicle from the side:
• an audible signal will sound from either theleft or right speaker, depending on whichside of your vehicle the object is approachingfrom.
• an icon will illuminate in the PAS 84
graphic
on the screen.
• an icon will appear in the Park Assist Cam-era's Top view.

Park Assist *
The Park Assist function can help the driver
when maneuvering in tight spaces by indicating distances to obstacles using audible signals andgraphics in the center display.
Display view showing obstacle zones and sensor sec- tors.
The center display shows an overview of the vehi- cle in relation to objects that have been detected. The marked sector indicates where the obstacle is located. The closer the vehicle symbol is to amarked sector, the closer the detected obstacleis to your vehicle. The audible signals will also speed up the closer the obstacle is to the vehicle. The volume of theaudio system will be automatically lowered. Audible signals for obstacles in front and to the sides of the vehicle are active when the vehicle is moving but will cease after the vehicle has beenstationary for approx. 2 seconds. Audible signalsfor obstacles behind the vehicle will remain activeeven when the vehicle is stationary. If a detected obstacle is within 30 cm (1 ft) from the front or rear of the vehicle, the tone willbecome constant and the active sensor's fieldclosest to the vehicle symbol will be filled in. The volume of the Park Assist audible signals can be adjusted while the signal is being given using the
>II knob or in the center display's Top
view under
Settings.
NOTE
• Acoustic warnings are only given for objects directly in front of the vehicle'spath.
WARNING
•The Parking Assist function is supple- mentary driver support intended to facili-tate driving and help make it safer – itcannot handle all situations in all traffic,weather and road conditions.
• The parking sensors have dead/blindspots where objects cannot be detected.
• Pay particular attention to people andanimals near the vehicle.
• Parking Assist is not a substitute for thedriver's attention and judgment. The driveris always responsible for ensuring thevehicle 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.

CAUTION
Objects such as chains, thin and glossy poles or low obstacles may end up in the "signalshadow" and then go temporarily undetectedby the sensors – the pulsating tone may thenunexpectedly stop instead of becoming aconstant tone as expected. The sensors cannot detect high objects, such as protruding ramps.
• In such situations, pay extra attention andmaneuver/drive the vehicle very slowly orstop the current parking maneuver –there may be a high risk of damage tothe vehicle or other objects since infor-mation from the sensors is not alwaysreliable in such situations.
CAUTION
In some circumstances, the Park Assist Sys- tem may produce false warnings due to exter-nal sound sources with the same ultrasonicfrequencies as those the system works with. Examples of such sources are horns, wet tires on asphalt, pneumatic brakes, exhaust noisefrom motorcycles, etc.
NOTE
When a trailer hitch is configured with the vehicle electrical system, the trailer hitch pro-trusion is included when the function meas-ures the distance to objects behind the vehi-cle.

Brake Assist System
The brake enhancing system, Brake Assist
System (BAS), helps increase braking force andthereby reduce braking distance.
The system monitors the driver's braking habits and increases braking force when necessary.Braking force can be increased up to the point atwhich the ABS intervenes. The function is deacti-vated when pressure on the brake pedal isdecreased.
NOTE
When BAS is activated, the brake pedal will go down slightly more than usual. Press(hold) down the brake pedal as long as nec-essary. When the brake pedal is released, all braking ceases.
Related information
• Brakes (p. 399)
Braking on wet roads
Prolonged driving in heavy rain without braking may cause braking effect to be slightly delayedthe first time the brakes are applied.
This may also occur after washing the vehicle. It will then be necessary to apply greater pressureto the brake pedal. You should therefore maintaina greater distance to the vehicle ahead. Firmly apply the brakes after washing the vehicle or driving on wet roads. This helps warm up thebrake discs, enabling them to dry more quicklyand protecting them against corrosion. Considerthe current traffic situation when braking.
