Switching on
- To switch on the adaptive cruise control, pull
the lever up to position 1 until it engages.
Storing the speed and activating regulation
If you have switched the system on, you can set
the current speed as the "regulated speed" and
activate regulation:
- Press the [SET] button 2. The set speed is indicated
with a marking in the speedometer 1, fig. 108 and shown in the instrument
cluster.
- To save the speed while the vehicle is stationary,
also hold the brake pedal down.
You can set any speed between 15 mph
(20 km/h)1) and the maximum possible speed
range 32), fig. 108.
1) Analog instrument cluster: 20 mph (30 km/h)
2) Depends on the country and engine
Pausing cruise control
The control can be stopped at any time:
- While driving or when the vehicle is stationary:
Press the lever away from you in the direction
of the arrow. Or
- While driving: Press the brake pedal.
The indicator light turns off.
Resuming regulation
The previously set speed can be resumed at any
time after a pause.
- To resume cruise control while driving, pull the
lever toward you in the direction of the arrow.
- To resume cruise control when stationary, pull
the lever toward you in the direction of the arrow
while pressing the brake pedal.
Changing the speed
- To increase or decrease the set speed in smaller
increments, briefly tap the lever toward (+) or
(0) to the first level.
- To increase or decrease the set speed in larger
increments, briefly tap the lever toward (+) or
(0) to the second level.
- To increase or decrease the set speed continuously,
hold the lever toward (+) or (-) until the
marking in the speedometer (1),
fig. 108 has reached the desired speed.
Applies to: vehicles with predictive control: Predictive
control can automatically adjust the set
speed based on traffic and road conditions.
Preselecting a speed
You can also preselect the speed when adaptive
cruise control is not active by moving the lever in
the desired direction (+)/(-). Activate the previously
selected speed by pulling the lever toward
you in the direction of the arrow.
Switching off
If you do not want to use the adaptive cruise control
for a long period of time, you can switch it
off.
- Push the lever away from you into position (0)
until it clicks into place.
The indicator light and the set speed will turn off.
WARNING
- Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras.
- The activated adaptive cruise control is only
an assist system, and the driver is still responsible
for controlling the vehicle. The
driver is especially responsible for braking,
steering, starting to drive, and controlling
the speed and the distance from other
vehicles.
- Turn on the adaptive cruise control only if
the surrounding conditions permit it. Always
adapt your driving style to the current visual,
weather, road, and traffic conditions.
- Switch adaptive cruise control off temporarily
when driving in turning lanes, on expressway
exits or in construction zones. This prevents
the vehicle from accelerating to the
stored speed when in these situations.
- If you press the [SET] button (2) when driving
at speeds below 15 mph (20 km/h)1), the
minimum possible speed that the system
can maintain will be set. If no vehicle is detected
ahead of you, the vehicle will accelerate
up to that speed.
Tips
- Always keep your hands on the steering
wheel so you can be ready to steer at any
time. The driver is always responsible for
adhering to the regulations applicable in
the country where the vehicle is being operated.
- If you switch the ignition or the adaptive
cruise control system off, the set speed is
erased for safety reasons.
- When adaptive cruise control is switched
on, the ESC and ASR automatically switch
on.
- The system cannot be switched off or it may
be interrupted if the road exceeds the maximum
possible grade for safe operation.
