Changing the tolerance for the Automatic speed limiter
The speed limiter function (Automatic Speed Limiter - ASL) can be set for different tolerancelevels.
It is possible to increase/decrease the signed speed limit. If, for example, the car follows asigned speed limit of 70 km/h (43 mph) thedriver can instead choose to allow the car tomaintain 75 km/h (47 mph).
Buttons and symbols for functions.
–Press the steering wheel button (1)
until 70 km/h (43 mph) in the centre of the speedometer (4) changes to 75 km/h(47 mph).
> After which, the car uses the selected tol- erance 5 km/h (4 mph) as long as signs passed are showing 70 km/h (43 mph). The tolerance is followed until a road sign with a lower or higher speed is passed -then the car follows the new signedspeed limit instead and the tolerance isdeleted from the memory. If the Road Sign Information * function is
activated, the signed speed limit will then be shown with a RED indicator on thespeedometer. The tolerance is adjusted in the same way as thespeed setting is in the speed limiter.
NOTE
The maximum selectable tolerance is +/- 10 km/h (5 mph).

• the gear selector is moved to
N position
• the clutch pedal is held depressed for longerthan 1 minute
• the driver maintains a speed higher than thestored speed for longer than 1 minute.
The driver must then control the speed himself/herself. 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
Cruise control is temporarily disengaged and set in standby mode if:
• wheels lose traction
• engine speed is too low/high
• brake temperature is too high
• speed falls below 30 km/h (20 mph).

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).
