Road Sign Information (RSI) – limitations
RSI's camera has the same limitations as the human eye. See The camera’s limitations(p. 183) for more information about the cam-era's limitations. Signs that indirectly indicate the speed limit (such as a sign with a town's name and thepermitted speed limit) will not be registeredby RSI. Other factors that may interfere with RSI include:
• Faded signs
• Signs located in a curve
• Twisted or damaged signs
• Obstructed signs
• Signs that are partially covered by snow, ice, etc.

Before a speed can be set, the cruise control system must be engaged (put in standbymode).
–Press the CRUISE button (1).
> The symbol
illuminates and the text
(---) mph (5) indicates that cruise con-
trol is in standby mode.
NOTE
Putting cruise control in standby mode does not set a cruising speed.
Setting a speed
Use the or buttons set the vehicle's
current speed. The set speed is shown in the display.
NOTE
Cruise control cannot be engaged at speeds below 20 mph (30 km/h).
Adjusting the set speedAfter a speed has been set, it can be increased or decreased by using the
or buttons. 1. Press
or briefly and release the
button to increase or decrease vehicle speed by approximately 1 mph or 1 km/h.
> This will become the set speed when the button is released.
2. Press and hold one of these buttons to increase/decrease the speed in 1-mph or 1-km/h increments. Release the buttonwhen you have reached the desiredspeed.
NOTE
•A temporary increase in speed by pressing the accelerator pedal, for lessthan 1 minute (e.g. when passinganother car), does not affect the cur-rent cruise control setting. The vehiclewill automatically return to the previ-ously set speed when the acceleratorpedal is released.
• If one of the cruise control buttons iskept depressed for more than approx.1 minute cruise control is disengaged.The engine must then be switched offin order to reset cruise control.

Toggling between ACC and CC (standard Cruise Control)
Adaptive Cruise Control (ACC) helps the driver maintain a safe distance/time interval tothe vehicle ahead.
Switching from ACC to CCThis may be useful if, for example, the radarsensor is obstructed in some way. SeeAdaptive Cruise Control – limitations (p. 159)for additional information.
• Press and hold the
button; the symbol
in the instrument panel will switch from
to .
> This activates the standard cruise control function (see Cruise control (CC) – intro- duction (p. 147)).
WARNING
Switching from ACC to CC means that:
• Your vehicle will
no longer automati-
cally maintain a set distance to a vehi- cle ahead.
• Only the set speed will be maintainedand the driver will have to apply thebrakes when needed.
Switching from CC to ACC
Switch off cruise control by pressing once
or twice as needed according to the instruc- tions in the previous section "Turning ACC off completely." The next time the system isswitched on, ACC will be reactivated.

Cruise control (CC) – deactivating
Cruise control is designed to assist the driver by maintaining a set speed. It is primarilyintended for use on long straight roads insteady traffic, such as on highways and othermain roads.
Automatic deactivationThe cruise control is automatically deacti-vated
temporarily if one of the following
occurs: • If the speed drops below approximately 20 mph (30 km/h).
• When the brake pedal is depressed.
• If the gear selector is moved to positionN
.
• During wheel spin or wheel lock-up.
• If the vehicle's speed is increased byusing the accelerator pedal for more than1 minute.
• Engine speed (rpm) is too high or too low.
The currently set speed will be saved in the system's memory.
Temporary deactivationThe driver can temporarily deactivate thecruise control by pressing 0. The saved
speed is shown in brackets in the informationdisplay.

Function
Function overview 1
Warning light, braking by driver required
Controls in steering wheel
Radar sensor in front grille
Adaptive Cruise Control consists of: • A cruise control system to maintain a set speed
• A system to maintain a set distance to thevehicle ahead, which is expressed as atime interval. For example, you canchoose to remain approximately 2 sec-onds behind the vehicle ahead. Theactual distance required to maintain a2-second interval will vary according thespeed of the vehicles.

WARNING
Adaptive Cruise Control only warns of vehicles detected by the radar sensor, seeAdaptive Cruise Control – limitations(p. 159). In some cases there may be nowarning or the warning may be delayed.The driver should always apply the brakeswhen necessary.
Steep inclines and/or heavy loadsACC is primarily intended for use on fairly level roads. The system may have difficultymaintaining the correct distance to a vehicleahead on steep inclines, if the vehicle is car-rying a heavy load or is towing a trailer. Inthese situations, the driver should always beprepared to apply the brakes if necessary.

NOTE
The driver's door must be closed and the driver's seat belt must be fastened beforeACC can be put in active mode. If the driv-er's seat belt is taken off or if the driver'sdoor is opened, ACC will return to standbymode.

Adaptive Cruise Control – setting speed
Setting a speedOnce ACC has been put in standby mode:
Controls and display
Put in active mode and set a speed (each additional press increases/decreasesspeed by 1 mph (approximately 2 km/h))
• Press
or (4).
> The set speed, for example 60 mph (5), will be magnified for several seconds and the frame around the speed will changecolors from white to green to indicate
that this speed has been stored (set).
When this symbol has changed col-ors from white to green , ACC is in
active mode and the vehicle will
maintain the set speed.
This symbol indicates that you are approaching a vehi-cle ahead. ACC will switch from main- taining a set speed to main-
taining a set distance from
that vehicle.
When this happens, a speed range will be indicated on
the speedometer: The higher speed (the cur-
rently set speed (5)) will be marked in green.
The lower speed in the range is the speed of
the vehicle ahead.
Changing the set speed
• After a speed has been set, it can be increased or decreased by briefly press- ing the
or buttons. Each time one
of these buttons is pressed, the vehicle's speed changes by 5 mph or 5 km/h. If thespeed is increased by pressing the accel-erator pedal, the vehicle's speed whenthe button is pressed will be set.
• Press and hold one of these buttons toincrease/decrease the speed in 1-mph or1-km/h increments. Release the buttonwhen you have reached the desiredspeed.
NOTE
•If one of the Adaptive Cruise Control buttons is pressed for more thanapproximately one minute, ACC will bedeactivated. The engine must then beswitched off and restarted to resetACC.
• In some situations Adaptive CruiseControl cannot be put in active mode.

Adaptive Cruise Control – setting time interval
Setting a time interval
Controls and display
Decrease/increase time interval
The set time interval to vehicles ahead can be increased by pressing
and decreased by
pressing
. The current time interval is
shown briefly in the display following adjust- ment. Different time intervals canbe selected and are shown in the instrument panel
2
as 1–5
horizontal bars. The greater the number of bars, thelonger the time interval. Onebar represents a time interval
of approximately 1 second; 5 bars is approxi-mately 3 seconds.
To set/change a time interval:
• Press the
/ buttons (3).
At low speeds, when the distance to the vehi- cle ahead is short, ACC increases the timeinterval slightly. In order to follow the vehicleahead as smoothly as possible, ACC allowsthe time interval to vary considerably in cer-tain situations.
WARNING
• Only use a time interval that is suitable in current traffic conditions.
• A short time interval gives the driverlimited reaction time if an unexpectedsituation occurs in traffic.
