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, the automaticbraking function will be triggered. This occurswhether or not the driver is pressing the brakepedal. Full braking force will be applied to reducethe speed at impact or reduced braking effect willbe applied if this is sufficient to avoid the colli-sion. The seat belt tensioners may be activated along with the automatic braking function. See "Seatbelt tensioners" for more information. In certain situations, auto-braking may begin with a limited braking force before applying full brak- ing force. If City Safety has prevented a collision, the vehi- cle will be kept at a standstill until the drivertakes action. If the vehicle has slowed to avoidcolliding with a slower-moving vehicle ahead, yourspeed will be reduced to that vehicle'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 mes- sage will appear in the instrument panel to notifythe driver that the function is/was activated.
WARNING
City Safety may not be used to change how the driver operates the vehicle. The drivermust not only rely on City Safety to brake thevehicle.

Setting a warning distance for CitySafety
City Safety is always active, but the function's warning distance can be adjusted.
NOTE
The City Safety function cannot be deacti- vated. It is activated automatically each timethe engine/electric motor is started.
The alert distance determines the sensitivity of the system and regulates the distance at whichthe light, sound and brake pulsations will be acti-vated. To select warning distance:
1. Select
SettingsMy CarIntelliSafe in
the center display's Top view.
2. Under
City Safety Warning, tap Late,Normal or Early to set the desired warning
distance.
If the driver feels that the
Early setting is giving
too many warnings or finds them irritating, the
Normal or Late warning distance settings can
be selected instead. If the driver feels that the warnings are too fre- quent and distracting, the warning distance canbe reduced. This will reduce the total number ofwarnings, but it will also result in City Safety pro-viding warnings at a later stage.

Rear Collision Warning
The Rear Collision Warning (RCW) function can help the driver avoid rear-end collisions fromvehicles approaching from behind.
RCW is automatically activated each time the engine is started. RCW can warn the driver of a potential collision with vehicles approaching from behind by rapidlyflashing the turn signals. If, at a speed below 30 km/h (20 mph), the RCW function detects that the car is in danger of beinghit from behind, the seatbelt tensioners may ten-sion the front seatbelts and activate the WhiplashProtection System safety system. Immediately before a collision from behind, RCW may also activate the foot brake in order toreduce the forward acceleration of the car duringthe collision. However, the brakes will only beapplied if your vehicle is stationary. The brakeswill be immediately released if the acceleratorpedal is depressed.

• Whiplash Protection System (p. 46)
Rear Collision Warning limitations
In some situations, it may be difficult for RCW to warn the driver of a collision risk.
This may be the case if:
• the vehicle approaching from the rear is detected at a late stage
• the vehicle approaching from the rearchanges lanes at a late stage
• the vehicle approaching from the rear is mov-ing at a speed above 80 km/h (50 mph)
• a trailer, bicycle holder or similar is con-nected to the vehicle's electrical system - theRCW function will then be automaticallydeactivated.
NOTE
In certain markets RCW does
not warn with
the direction indicators due to local traffic regulations – in such cases, that part of thefunction is deactivated.
NOTE
The warning with direction indicators for Rear Collision Warning is deactivated if the colli-sion warning distance in the City Safety func- tion is set to the lowest level "
Late".
The seat belt tensioning and braking func- tions remain active.

Activating/deactivating Cross TrafficAlert
The driver can choose to deactivate the CTA 90
function as follows:
Press the Cross Traffic Alertbutton in the center display's Function view.
• GRAY button indicator light - CTA is deacti- vated.
• GREEN button indicator light - CTA is acti-vated.
CTA is automatically activated each time theengine is started.

functionality may be reduced in certain
situations.
CTA does not function optimally in all situations and has certain limitations. The CTA sensors, forexample, cannot "see" through other parkedvehicles or objects blocking the vehicle. Below are a few examples of situations in which CTA's field of vision may be initially limited andapproaching vehicles may therefore not bedetected until they are very close to your vehicle:
The vehicle is parked very far into a parking space.
In a diagonal parking space, CTA may be completely "blind" on one side of your vehicle.

CTA's field of vision.
However, as you back your vehicle slowly out of a parking space, CTA's field of vision changes inrelation to the obstructing vehicle/object and itsblind zone is reduced.

WARNING
•
The Driver Alert Control function is sup- plementary driver support intended tofacilitate driving and help make it safer –it cannot handle all situations in all traffic,weather and road conditions.
• Driver Alert Control must not be used toextend a period of driving. The drivershould plan in breaks at regular intervalsand make sure they are well rested.
• Driver Alert Control is not a substitute forthe driver's attention and judgment. Thedriver is always responsible for ensuringthe vehicle is driven in a safe manner, atthe appropriate speed, with an appropri-ate distance to other vehicles, and inaccordance with current traffic rules andregulations.
WARNING
An alarm from Driver Alert Control should be taken very seriously since a sleepy driver isoften not aware of their own condition. If the alarm sounds or you feel fatigued:
• Stop the vehicle safely as soon as possi- ble and rest.
Studies have shown that it is just as danger- ous to drive while tired as it is to drive underthe influence of alcohol or other stimulants.

Using the steering wheel paddles *to shift
The steering wheel paddles are a supplement to the gear selector and make it possible to shiftmanually without removing your hands from thesteering wheel.
Activating the steering wheel paddlesIn order to shift gears using the paddles, they must first be activated:
–Pull one of the paddles toward the steering wheel.
> A number in the instrument panel indi- cates the current gear being used.
Instrument panel when the paddles are activated for shifting.
ChangeTo shift one gear:
–Pull one of the paddles toward the steering wheel and then release.
"-": Shift down one gear.
" + ": Shift up one gear.
As long as the engine speed (rpm) is within the permissible range for the selected gear, a gearshift will take place each time a paddle is pulled. After each gear shift, a number indicating the current gear will be displayed in the instrumentpanel.
Turning off Start/Stop
Manual deactivation in gear D and B
–Deactivate the paddles by pulling the right paddle ( +) toward the steering wheel and
holding it until the number of the current gear is no longer displayed in the instrumentpanel. > The transmission will revert to gear D or B
depending on which gear was selected before the paddles were activated.
Automatic deactivation
In gear position D, the steering wheel paddles
are deactivated after a short period of time if they are not used. The number of the current gear willno longer be displayed in the instrument panel. In gear position B, the paddles will not activate
automatically.

the hill is and without the brakes needing to be applied. The brake lights will illuminate when thefunction is activated. The driver can brake to stop or slow the vehicle at any time by depressing the brake pedal. HDC is activated along with Low Speed Control (LSC), which facilitates and improves traction andcontrol on rough and slippery surfaces. The sys-tem is intended to be used at low speeds, up toapproximately 40 km/h (25 mph).
To keep in mind when using HDC
•
If the function is switched off while driving ona steep downhill gradient, braking effect willbe gradually reduced.
• HDC can be used in gear positions
D and R,
and in manual gears 1 or 2.
• It is not possible to manually shift to thirdgear or higher when HDC is active.
NOTE
When LSC with HDC is activated in the OFF ROAD drive mode, the feel of the acceleratorpedal and engine response will change.
NOTE
This drive mode is not designed to be used for normal street driving.
NOTE
The function is deactivated when driving at high speeds and must be reactivated at lowerspeeds if so desired.
