WARNING
The driver support system only issues a warning for obstacles detected by its radarsensor – thus, a warning may come after adelay or not at all.
Never wait for a warning or assistance. Apply the brakes when necessary.
NOTE
Driver support can keep the vehicle sta- tionary for no more than 5 minutes – afterthat time the parking brake is applied andthe function is deactivated. The parking brake must be released before driver support can be reactivated.
Deactivation of the Auto-hold brake function
In certain situations, auto-hold will be deacti- vated when the vehicle is at a standstill andthe function will go into standby mode. This means that the brakes will be released and the vehicle could begin to roll. The driver mustactively apply the brakes to keep the vehiclestationary. This can occur if:
the driver depresses the brake pedal
the parking brake is applied
the gear selector is moved to the
P, N or R
positions
the driver puts the function in standby mode.
Auto Activate Parking BrakeIn certain situations, the parking brake will beapplied to keep the vehicle at a standstill. This occurs if the function is keeping the vehi- cle stationary using the brakes and:
the driver opens the door or unbuckleshis/her seat belt
the function has kept the vehicle at astandstill for more than approx. 5 minutes
the brakes overheat
the driver switches off the engine man-ually.

Drive mode for driver support The driver can choose different drive modes to determine how driver support shouldmaintain a time interval to the vehicle ahead.
Settings are made using the
DRIVE MODE
controls. Select one of the following:

Pure - Driver support will focus on provid-
ing good fuel economy, which will increase the time interval to the vehicleahead.

Hybrid - Driver support will focus on fol-
lowing the set time interval to the vehicle ahead as smoothly as possible.

Power - Driver support will focus on fol-
lowing the set time interval to the vehicle ahead more exactly, which could meanfaster acceleration and heavier braking.

1 - Collision warning
The driver is first alerted to the risk of an immi- nent collision. In vehicles equipped with a head-up display *,
a flashing warning symbol will be displayed on the windshield.
Collision warning symbol on the windshield.
NOTE
Visual warnings on the windshield may be difficult to notice in cases of strong sun-light, reflections, extreme light contrasts,or if the driver is wearing sunglasses or isnot looking straight ahead.
City Safety can detect pedestrians, cyclists or vehicles that are stationary, are moving in thesame direction as your vehicle and are aheadof your vehicle. City Safety can also detect pedestrians, cyclists or large animals that arecrossing the road in front of your vehicle. If there is a risk of a collision with a pedestrian, large animal, cyclist or another vehicle, thedriver will be alerted with light, sound and pul-sations in the brake pedal. At lower speeds,during hard braking or if the accelerator pedalis pressed, the brake pedal pulsation warningwill not be given. The intensity of the brakepedal pulsations varies according to the vehi-cle's speed.
2 - Brake assistance
If the risk of a collision increases after the colli- sion warning, brake support will be activated. If the system determines that the pressure the driver is exerting on the brake pedal is insuffi-cient to prevent the collision, brake supportwill increase pressure.
3 - Auto-brake
The automatic braking function is activated at the last moment. If the driver has not taken evasive action by this stage and a collision is imminent, theautomatic braking function will be triggered.This occurs whether or not the driver is press-ing the brake pedal. Full braking force will beapplied to reduce the speed at impact orreduced braking effect will be applied if this issufficient to avoid the collision.
The seat belt tensioner may be activated whenthe automatic braking function is triggered. In certain situations, auto-braking may begin with a limited braking force before applyingfull braking force. If City Safety has prevented a collision, the vehicle will be kept at a standstill until thedriver takes action. If the vehicle has slowed toavoid colliding with a slower-moving vehicleahead, your speed will be reduced to that vehi-cle's speed. Auto-braking can always be cancelled if the driver presses hard on the accelerator pedal.
NOTE
When City Safety activates the brakes, the brake lights come on.
When City Safety applies the brakes, a text message will appear in the instrument panelto notify the driver that the function is/wasactivated.
WARNING
City Safety may not be used to change how the driver operates the vehicle. Thedriver must not only rely on City Safety tobrake the vehicle.
