Changing Cruise Control speed
Changing a set speed
Function buttons and symbols (generic illustration)
–Change a set speed by pressing the (1)
or — (3) buttons briefly or by pressing and
holding them:
• Press briefly
: changes speed in
+/– 5 mph (+/– 5 km/h) increments. Each press changes the vehicle's speedby +/– 5 mph (+/– 5 km/h).
• Press and hold
: changes the speed
+/– 1 mph (+/– 1 km/h) at a time.Release the button when the set speedindicator (4)/(6) has moved to the desiredspeed.
If speed is increased by pressing the accelerator pedal before the
button is pressed, the vehi-
cle's speed when the button is pressed will become the set speed assuming that the accel- erator pedal is still depressed when the button ispressed. A temporary increase in speed, such as when passing another vehicle, does not affect the CCset speed. The vehicle will return to the set speedwhen the accelerator pedal is released. Alwaysobserve posted speed limits.
Engine braking instead of applying the
brakes
CC regulates speed by applying the brakeslightly. To avoid a loss of speed when drivingdown hills, use the engine braking functioninstead of letting the CC apply the brakes. In thissituation, the driver can temporarily deactivate theCC braking function. To do so:
–Press the accelerator pedal approx. halfway down and release it.
> CC will automatically deactivate the auto- matic brake function and will then only use the engine braking function.

Distance Alert *
Distance Alert is a function that alerts the driver if the time interval to the vehicle ahead is too short.
Distance Alert is active at speeds above approxi- mately 20 mph (30 km/h) and only reacts to avehicle ahead that is driving in the same direc-tion. No information is provided for vehicles driv-ing toward you, moving very slowly, or at a stand-still.
Warning light (generic illustration)
A warning light in the windshield glows steadily if your vehicle is closer to the one ahead than theset time interval.
NOTE
Strong sunlight, reflections, extreme light con- trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.
NOTE
Distance Alert only monitors distance to the vehicle ahead while Adaptive Cruise Control isin standby mode or off.
WARNING
Distance Alert only indicates the distance to the vehicle ahead. It does not affect thespeed of your vehicle.

Activating ACC (putting it in active mode and setting a speed)
Before ACC can be put in active mode:
• The driver's seat belt must be buckled and the driver's door must be closed.
• There must be a vehicle ahead (a target vehi-cle) within a reasonable distance or yourvehicle's current speed must be at least9 mph (15 km/h).
–With the symbol displayed (ACC is in
standby mode), press the
button (1) on
the left-side steering wheel keypad.
> This puts ACC in active mode and sets the vehicle's current speed, which is indi- cated by digits in the center of the speed-ometer. The
time interval to the vehi-
cle ahead will only be shownwhen two vehicles are dis-played.
A speed interval will also be indicated:
• The higher speed is the one set in ACC
• The lower one is the speed of the vehicle ahead (the target vehicle).

Setting an Adaptive Cruise Control time interval
ACC makes it possible to set various time inter- vals to the vehicle ahead.
Different time intervals to the vehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The greater the number ofbars, the longer the time inter-val. One bar between the vehi-
cles represents a time interval of approximately1 second; 5 bars is approximately 3 seconds. The same symbol appears if Distance Alert is activated.
• If the symbol shows two vehicle's, ACC is actively following the vehicle ahead (a targetvehicle).
• If only one vehicle is displayed, ACC is
not
actively following another vehicle.
Changing a time interval
Controls for setting a time interval
Reduce the time interval
Increase the time interval
Distance/time indicator
–Press buttons (1) or (2) to reduce or increase the time interval.
> The distance/time indicator (3) shows the current time interval.
In order to follow the vehicle ahead as smoothly as possible, ACC allows the time interval to varyconsiderably in certain situations. At low speeds,when the distance to the vehicle ahead is short,ACC increases the time interval slightly. • If ACC does not seem to react when it is put in active mode, this may be because the set time interval to the vehicle ahead does notallow an increase in speed.
• The higher the speed, the greater the dis-tance to the vehicle ahead for a given timeinterval.
• Only use time intervals permitted by localtraffic regulations.
WARNING
•
Only use a time interval that is suitable in current traffic conditions.
• A short time interval gives the driver lim-ited reaction time if an unexpected situa-tion occurs in traffic.
