Service interval display
The service interval display reminds you when your next
service is due.
Fi g. 14 D isplay:
Se rvice i nterval displ ay
The date for service is calculated automa tically. Based on the
average distance driven in previous months, a monthly driving
distance is calculated. As soon as the distance remaining to the next
service drops below the distance driven monthly, the service
reminder is initiated. The maximum period from one service to the
next is one year.
S erv ice reminder
30 days before the next service is due, a service reminder appears

Adaptive Light
When making a turn or driving around tight corners, the
relevant area of the road is better illuminated.
Adaptive Light (making turns)
Fig. 60 Adaptive Light
when turning and
driving through curves
An additional bulb in the headlight provides a cornering light@ in
addition to the low
beam @~ fig. 60. Adaptive Light is switched on
and off automatically depending on driving conditions .
When you activate the turn signal lever, the Adaptive Light for the
same side is switched on. Please note that the turn signal lever must
engage. Adaptive Light is not switched on if you only move the
turn signal
lever to the point of resistance to signal a lane
change~ page 73,
"Turn signal¢ c:> and high beam 110 lever ".
When driving around bends, Adaptive Light is controlled according
to steering wheel angle .
• I t is switched on in tight corners.
• It is not switched on in long, open bends.
Adaptive Light (in curves)
When driving through curves, the low beams @are automatically
controlled depending on driving speed and the steering wheel
angle.
Th e two main beams pivot at different angles so that there is no
unilluminated area in front of the vehicle.
[ i] Tips
• The system works up to a speed of about 43 mph (70 km/h). If the
speed is higher, it is not activated.
• Adaptive Light (in curves) functions at a speed of about
6 mph
(10 km/h) and is deactivated at speeds below about 4 mph
(6 km/h).•

The positive (+l battery terminal is protected by a plastic cover . This
cover must be removed to access the positive (+l terminal when
connecting jumper cables to start the engine.
Always heed the safety warnings, when working on the vehicle
battery or the vehicle electrical system to prevent injury.
The following WARNINGS are very important when
working on the battery:
Always heed the following WARNING SYMBOLS and safety pre­
cautions when working on the battery.
-
@
®
-Always wear eye protection.
Battery acid contains sulfuric acid. Always wear
gloves and eye protection.
No
-sparks
-flames
-smoking.
When a battery is charged, it produces hydrogen
gas which is explosive and could cause personal
injury.
Always keep the battery well out of reach of chil­
dren.
& WARNING
Whenever working on the battery or on the electrical system,
there is the risk of injury, accident and even fire. Read and heed the
following WARNINGS:
& WARNING (continued)
• Always wear eye protection. Do not let battery acid or any lead
particles get on your skin or clothing. Shield your eyes. Explosive
gases can cause blindness or other injury.
• Battery acid contains sulfuric acid. Sulfuric acid can cause
blindness and severe burns.
-Always wear gloves and eye protection. Do not tilt the
battery because acid could leak out of the ventilation openings.
- If you get battery acid in your eyes or on your skin, immedi­
ately rinse with cold water for several minutes and get medical
attention.
- If you should ingest any battery acid, seek medical attention
immediately.
• Do not expose the battery to an open flame, electric sparks or
an open light.
• Do not smoke.
• Do not interchange the positive and negative cables.
• When working on the battery, be sure not to short-circuit the
terminals with tools or other metal objects. This would cause the battery to heat up very quickly, which could lead to damage or
explosion and personal injury.
• When a battery is charged, it produces hydrogen gas which is
explosive and could cause personal injury.
• Always keep the battery well out of the reach of children .
• Before work is done on the electrical system, disconnect the
negative ground cable.
• Before performing any work on the electrical system, switch off
the engine and ignition as well as any electrical equipment. The
negative cable on the battery must be disconnected. If you are just
going to replace a light bulb, then it is enough to switch off the
lights.
• Before disconnecting the battery, switch off the anti-theft
alarm system! Otherwise you will set off the alarm.

It is becoming increasing ly more and more difficult to replace
vehic le light bulbs since in many cases, other parts of the car must
first be removed before you are able to get to the bu lb. This applies
especially to the light bulbs in the front of your car which you can
only reach through the engine compartment.
