Clear vision
The head lights only work when the ignition is switched on . While
starting the engine or when switching off the ignition, the head ­
lights will go off and only the side marker lights will be on.
After starting the engine, the xenon headlights are automatically
adjus ted to the load and angle of the vehic le (for example, during
acceleration, braking) . This prevents oncoming traffic from experi ­
encing unnecessary headlig ht g lare from your xenon head ligh ts .
If the system is not operating properly, a warning symbol in the
Auto -Check Control is displayed
=> page 36.
With the side marker lights or head ligh ts switched on, the sym bol

&, WARNING (continued)
• Please note that inadvertently "resting" your foot on the accel­
erator pedal causes the cruise control not to brake . This is because
the cruise control is overridden by the driver's acceleration.
[ i] Tips
The brake lights illumin ate as soon as the brakes decelerate
automatically. •
Changing speed
-Press lever@in the 0 or Q direction=> page 137,
fig. 149 to increase or decrease your speed.

Change speed in increments of 1 mph (1 km/h) by lightly pressing
the lever . If you keep the lever pressed down, you will alter your
speed in 5 mph (10 km/h) increments.
You can also press the accelerator pedal down to increase your
speed, e.g. if you want to pass someone. The speed you saved
earlier will resume as soon as you release the accelerator pedal.
If, however, you exceed your saved speed by 5 mph (10 km/h) for
longer than 5 minutes, the cruise control will turn off temporarily.
The green symbol in the
display=> page 137, fig . 150 is replaced
with a white symbol. The saved speed remains the same. •
Presetting your speed
You can preset your desired speed while the vehicle is not
moving.
-Turn on the ignition .
-Pull lever@ into position G) => page 137, fig. 149 .
-Press the lever in the 0 or Q direction to increase or
decrease your speed.

• If the Adaptive Cruise Control initiates braking, the hydraulic
brake system is under pressure. Therefore, the brake pedal distance
is shorter and the peda l feels "harder" .
• I f you use the accelerator to go faster than the speed being main ­
