Automatic headlamp mode
GWarning!
If the exterior lamp switch is set to 0066, the
headlamps will not automatically come on
under foggy conditions.
To minimize risk to you and to others, activate
headlamps by turning exterior lamp switch to
0064 when driving or when traffic and/or
ambient lighting conditions require you to do
so.
In low ambient lighting conditions, only switch
from position 0066 to 0064 with the vehicle
at a standstill in a safe location. Switching
from 0066 to 0064 will briefly switch off the
headlamps. Doing so while driving in low
ambient lighting conditions may result in an
accident.
The automatic headlamp feature is only an aid
to the driver. The driver is responsible for the
operation of the vehicle’s lights at all times.XSwitching on: Turn the exterior lamp
switch to position 0066.
When ambient light is low: When the
SmartKey is in starter switch position 1 or
when the KEYLESS-GO start/stop button has
been pressed once, the parking lamps 38
come on automatically.
When the engine is running, the low-beam
headlamps come on additionally.
When ambient light is bright: When the
SmartKey is in starter switch position 1 or
when the KEYLESS-GO start/stop button has
been pressed once, all lamps are off.
When the engine is running, the daytime
running lamps 39
come on automatically.
When the low-beam headlamps are switched
on, the green indicator lamp 006C in the
exterior lamp switch comes on.
Once the low-beam headlamps are on, the
high-beam headlamps are also available.
Daytime running lamp mode
In Canada, the daytime running lamp mode is
mandatory and therefore in a constant mode.
In the USA, the daytime running lamp mode
is deactivated by default.
XActivate the daytime running lamp mode
using the control system, see “Switching38 When the parking lamps are on, the tail lamps, the license plate lamps, the side marker lamps, and the
instrument cluster illumination are also on.
39 USA only: The daytime running lamp mode must be activated via the control system.Lighting299Controls in detail221_AKB; 6; 20, en-USd2ugruen,Version: 2.11.8.12009-09-24T13:28:17+02:00 - Seite 299Z
The driving safety systems ABS, Adaptive
Brake, Adaptive Brake Lights, BAS, BAS
PLUS, EBP, ESC and PRE-SAFE® Brake are
described in the “Safety and security” section
(Y page 63).
Cruise control
The cruise control maintains the speed you
set for your vehicle automatically.
The use of the cruise control is recommended
for driving at a constant speed for extended
periods of time.
The currently set speed or last set speed
(“Resume” function) appears in the
multifunction display for approximately
5 seconds. The set speed is shown by a
triangle in the speedometer and the
corresponding speedometer segments from
the selected speed to the vehicle maximum
speed in the multifunction display are
illuminated.
GWarning!
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle’s speed
and for safe brake operation.
Only use the cruise control if the road, traffic,
and weather conditions make it advisable to
travel at a constant speed.
RThe use of the cruise control can be
dangerous on winding roads or in heavy
traffic because conditions do not allow safe
driving at a constant speed.
RThe use of the cruise control can be
dangerous on slippery roads. Rapid
changes in tire traction can result in wheel
spin and loss of control.
RDeactivate the cruise control when driving
in fog.
The “Resume” function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed.
GWarning!
When the cruise control is braking, the brake
pedal is retracted (i.e. depressed
automatically). The pedals’ range of motion
must not be impeded by any obstacles:
RDo not place any objects in the footwell.
RMake sure that the floormats and carpets
are securely in place.
RDo not rest your foot underneath the brake
pedal, as it could otherwise be trapped.
You could otherwise cause an accident and
injure yourself and/or others.
