Distance Warning *
The Distance Warning function (Distance Alert) warns the driver if the time interval to the vehicleahead becomes too short.
Distance warning is active at speeds
above 30 km/h (20 mph) and only reacts to thevehicle ahead travelling in the same direction. Nodistance information is provided for oncoming,slow or stationary vehicles.
NOTE
Distance warning is deactivated during the time the adaptive cruise control is active.
WARNING
Distance warning only reacts if the distance to the vehicle ahead is shorter than the presetvalue - the speed of the driver's vehicle is notaffected.

.
In cars equipped with head-up display, a symbol is shown on the windscreen for as long as thetime interval to the vehicle ahead is shorter thanthe preset value. However, this presupposes that the
Show Driver Support function is activated
via settings in the car's menu system; see the heading "Head-up display" for how this works.
NOTE
Information on the windscreen may be diffi- cult to see in strong sunlight and when wear-ing sunglasses.

The function is activated/deac- tivated in function view in thecentre display.
–Tap on the Distance Alert button in func-
tion view.
> Distance warning is activated/deactivated, a green/grey indicator is displayed in the button.
Setting the time interval for Distance warning
Different time intervals to the vehicle in front can be selectedand shown in the driver displayas 1-5 horizontal lines - themore lines the longer the timeinterval. One line representsabout 1 second to the vehicle
in front, 5 lines represents about 3 seconds.
The same symbol is also shown when the adap- tive cruise control function is activated.

–Press the steering wheel button (1) or (2) to increase or decrease the time interval.
> The distance indicator (3) shows the cur- rent time interval.
NOTE
The higher the speed the longer the calcula- ted distance in metres for a given time inter-val. The set time interval is also used by the Adaptive Cruise Control function. Only use the time intervals permitted by local traffic regulations.

WARNING
The adaptive cruise control only warns of vehicles which its radar unit has detected -hence a warning may not be given, or it maybe given with a certain delay. Do not wait for awarning without braking when so required.

Activating and starting the adaptive cruise control *
The adaptive cruise control (Adaptive Cruise Control - ACC) must first be activated and thenstarted if it is to control the speed and distance.
NOTE: The illustration is schematic - details may vary depending on car model.
Activate Adaptive Cruise ControlImmediately after the engine is started the Adap- tive Cruise Control is in the standby mode.
–Press ◀ (2) or ▶ (3) to browse to the sym-
bol/function
(4).
> The symbol is displayed and Adaptive Cruise Control is set in standby mode.
Start Adaptive Cruise ControlIn order to start the ACC the following require- ments apply:
• The driver's seatbelt must be buckled andthe driver's door must be closed.
• There must be a vehicle (the "target vehicle")within reasonable distance in front of the car,or the current speed must be at least15 km/h (9 mph).
• For cars with manual gearbox. Speed mustbe at the lowest 30 km/h (20 mph).
–With the symbol/function displayed -
press the steering wheel button
(1).
> Adaptive cruise control starts and the cur- rent speed is stored, which is shown in figures in the centre of the speedometer.
The time interval is onlyadjusted to the vehicle aheadby the ACC when the distancesymbol shows two vehicles.
At the same time a speed range is marked. The higher speed is the stored/selected speed and thelower speed is that of the vehi-cle ahead (target vehicle).

Managing the speed of the adaptive cruise control *
The adaptive cruise control (Adaptive Cruise Control -ACC) can be set to different speeds.
NOTE: The illustration is schematic - details may vary depending on car model.
–Change the stored speed with short or long presses on steering wheel button
(1) or
- (3):
• Use
short presses to adjust +/- 5 km/h
(+/- 5 mph) with each press.
• Hold the button depressed
to adjust
+/- 1 km/h (+/- 1 mph) and release
when the driver display's marking (4) is at
the desired speed .
> The speed set after the last press is stored in the memory. If the driver increases the car

Setting the time interval for the adaptive cruise control *
The adaptive cruise control (Adaptive Cruise Control -ACC) can be set to different time inter-vals.
Different time intervals to the vehicle in front can be selectedand shown in the driver displayas 1-5 horizontal lines - themore lines the longer the timeinterval. One line representsabout 1 second to the vehicle
in front, 5 lines represents about 3 seconds. The same symbol is also shown when the Dis- tance Warning function is activated.
NOTE
When the symbol in the driver display shows two cars, ACC is following the vehicle in frontat a pre-set time interval. When only one car is shown, there is no vehi- cle within a reasonable distance ahead.
Control for time interval.
Decrease time interval
Increase time interval
Distance indicator
–Press the steering wheel button (1) or (2) to increase or decrease the time interval.
> The distance indicator (3) shows the cur- rent time interval.
The adaptive cruise control allows the time inter- val to vary significantly in certain situations inorder to allow the car to follow the vehicle in frontsmoothly and comfortably. At low speed, whenthe distances are short, the adaptive cruise con-trol increases the time interval slightly. Note that a short time interval only allows the driver a short time to react and take action if anyunforeseen problem should arise.
NOTE
Only use the time intervals permitted by local traffic regulations. If the adaptive cruise control does not appear to react when activated, this may be becausethe time distance to the vehicle in front is pre-venting an increase in speed. The higher the speed the longer the calcula- ted distance in metres for a given time inter-val.

Deactivating/activating the adaptive cruise control *
The adaptive cruise control (Adaptive Cruise Control - ACC) can be temporarily deactivatedso that it is set in the standby mode and canlater be reactivated.
Deactivate Adaptive Cruise Control and set it in standby mode
NOTE: The illustration is schematic - details may vary depending on car model.
To temporarily switch off Adaptive Cruise Control and set it in standby mode:
–Press the steering wheel button (2).
> The
symbol on the driver display
changes colour from WHITE to GREY and the stored speed in the centre of thespeedometer changes from BEIGE toGREY. In standby mode, the driver must him/herselfcontrol both speed and distance. When the adaptive cruise control is in standby mode and the car drives too close to a vehicleahead, the driver is warned about the short dis-tance by the Distance Warning function instead(see reference to the heading "Distance Warn-ing" at the end of this section).
Standby mode on driver intervention
The adaptive cruise control is temporarily deacti- vated and set in standby mode if:
• the foot brake is used
• the gear selector is moved to
N position.
• the driver maintains a speed higher than thestored speed for longer than 1 minute.
• the clutch pedal is depressed for approx. 1minute - applies to cars with manual gearbox.
In this situation, the driver must intervene andadapt the speed and distance to the vehicleahead. A temporary increase in speed with the accelera- tor pedal, e.g. during overtaking, does not affectthe setting - the car returns to the last storedspeed when the accelerator pedal is released.
Automatic standby mode
Adaptive cruise control is dependent on other systems, e.g. stability control/anti-skid ESC. If anyof these systems stops working, adaptive cruisecontrol is switched off automatically. In the event of automatic deactivation a signal willsound and a message is shown in the driver dis-play. The driver must then intervene and adaptthe speed and distance to the vehicle ahead. Automatic deactivation may occur if:
• the speed is below 5 km/h (3 mph) and ACC is uncertain whether the vehicle ahead is astationary vehicle or an object, such as aspeed bump.
• the speed is below 5 km/h (3 mph) and thevehicle ahead turns off so that ACC nolonger has a vehicle to follow.
• speed is reduced to below 30 km/h(20 mph) - only applies to cars with manualgearbox.
• the driver opens the door
• the driver takes off the seatbelt
• engine speed is too low/high
• wheels lose traction
• brake temperature is high
• the parking brake is applied
• the camera and radar unit is covered by e.g.snow or heavy rainfall (camera lens/radiowaves are blocked).
