- Pressing the knob will prevent unintentional changes.
(I] Tips
The illumination for the instrument cluster lights up whenever you
switch on the ignition with the vehicle headlights off . As the daylight
fades, the instrument cluster illumination likewise dims automati­
cally and will go out completely when the outside light is very low.
This feature is meant to remind you to switch on the headlights when
outside light conditions become poor. •
Appli es to veh icles : wi th xenon headlights
Xenon headlights
After starting the engine , the xenon headlights are automatically
adjusted to the load and angle of the vehicle (for example, during
acceleration and braking). This prevents oncoming traffic from expe­
riencing unnecessary headlight glare from your xenon headlights .
If the system is not operating properly, a warning symbol in the Auto­
Check Control is displayed~
page 37. •
Ap plies to vehi cles: with adap tive light
Adaptive light
When driving around bends, the relevant area of the road
is better illuminated.
Fig. 69 Adaptive light
when driving
The benefit of adaptive light is that the curve and the edge of the road
are better illuminated ~ fig. 69. Dynamic adaptive light is controlled
automat ically, depending on vehicle speed and steering wheel angle.
When driving around bends, the headlights are controlled according
to steering wheel angle . So that there is no black hole ahead of the
vehicle , the two main beams pivot at different angles. .,.

_& WARNING
• Unintended vehicle movement can cause serious injury.
- When the selector lever is
in a driving position, the vehicle
may creep, even at idle speed. Therefore do not release the
parking brake
or foot brake until you are ready to move,
because power is transmitted to the wheels as soon as a driving
position is engaged.
- Do not accelerate while selecting a driving position . At this
time the engine must be at idle speed so that undue stress is
not placed on the clutches in the transmission.
- Remember : · even when stopped briefly with the automatic
transmission
in " D", "S" or "R", engine power is being trans­
mitted to the wheels. Your vehicle could "creep " forward or
backward. When stopped, keep the brake pedal fully
depressed and use the parking brake if necessary to keep the
vehicle from rolling .
• If the selector lever is unintentionally moved into N while you
are driving, take your foot off the accelerator pedal and wait for
the engine to return to idle speed before selecting a driving posi­
tion.
• Never shift into "R" or "P " when the vehicle is in motion .
• Never get out of the d river's seat when the engine is running.
• If you must get out of the vehicle , move the selector lever
securely into the P position and apply the parking brake firmly .
• If the engine must remain running, never have any driving
position engaged when checking under the hood. Make sure the
selector lever has securely engaged and is locked in "P " with the
