Adjust your desired speed to the traf-
fic conditions and remain ready to
brake at all times. Great differences in
speed to the vehicles driving ahead, e.g.
when quickly approaching a truck or when
another vehicle swerves into your lane,
cannot be compensated for by the sys-
tem.<
Activate system
From approx. 20 mph/30 km/h you can
activate the system by pressing the lever
forward or pulling it back:
The current driving speed is stored as a
desired speed and briefly displayed in the
speedometer, refer to arrow.
If the display ACC --- mph/km/h
appears briefly in the speedometer,
it might be that conditions necessary for
operation are not currently being met.
To call up Check Control messages, refer
to page84.<
1 Desired speed store and increase
Press the lever forward:
The system applies and stores your current
speed as a desired speed. The speedome-
ter indicates this speed.
Subsequently pressing forward increases
the desired speed to the next 5-mile place/
10 km/h.
Each time the lever is pressed forward
again, the desired speed is increased by
another 5 mph/10 km/h until a maximum of
110 mph/180 km/h is reached. The speed
then displayed is stored and reached on a
clear road.
2 Desired speed store and decrease
Pull back the lever:
The current driving speed is rounded off to
the next 5-mile place/10 km/h, displayed
and stored.
Each time the lever is pulled back again,
the desired speed is decreased by another
5 mph/10 km/h until the minimum speed of
20 mph/30 km/h is reached. The speed
then displayed is stored and reached on a
clear road.
3 Deactivate system
Press the lever up or down while the sys-
tem is active. The displays in the speedom-
eter disappear. You can use the system
again as required.
In addition, the system is deactivated auto-
matically:
>When you apply pressure to the brake
pedal
>When you select the automatic trans-
mission's neutral range N
>When you deactivate the DSC Dynamic
Stability Control
>When you actuate the parking brake
during driving
>When the system reduces the speed to
below 20 mph/30 km/h due to a traffic
situation.
The system deactivates automatically
when the speed is set to below
20 mph/30 km/h. A gong sounds and a
message appears in the Check Control.
The active intervention of the driver is
required, otherwise there is an accident
danger.<
Background lighting
You can switch off the background lighting
of the speedometer and tachometer
>when you have deactivated the system
>when the prewarning field in the
tachometer has gone out, refer to
page81
>when the destination guidance system
of the navigation system is deactivated.

Driving
80 In approaching a curve, it is possible that
active cruise control would react briefly to
a vehicle in the adjacent lane. In addition,
the system can sense if your vehicle is in
a curve and may not accelerate. If your
vehicle decelerates in either case, you can
choose to overcome the deceleration by
briefly pressing the accelerator pedal.
Driver interventions
Remember actions by the driver
always supersede and take priority
over the system's automatic actions. Any-
time the driver presses down on the accel-
erator pedal, any automatic braking action
by the system is interrupted until the pedal
is fully released. After doing this, release
the accelerator and the system again con-
trols your cruising speed and distance set-
ting. While driving with activated system,
resting your foot on the accelerator pedal
will cause the system not to brake even if
necessary. Be certain that floormats or
other objects on the vehicle floor do not
interfere with movement of the accelerator
pedal.<
While active cruise control is capable
of braking your vehicle automatically
when you approach a slower vehicle
ahead, it is important to be aware that the
ability of the system to apply the brakes is
also limited, if you are driving down a steep
grade or when you reduce your desired
speed sharply. The system cannot stop
your vehicle. It uses only a portion of brak-
ing system capacity and does not utilize the
full capacity of the vehicle braking system.
Therefore, the system cannot decrease
your speed for large differences in speed
between your vehicle and the vehicle ahead. Examples: during emergency brak-
ing, when you approach a vehicle traveling
at a much lower speed than your own
speed such as approaching a toll booth or
when a much slower vehicle cuts in front of
you at close range.<
Whenever active cruise control
recognizes a situation that
requires driver braking because
the system capacity has been
reached or has been exceeded,
the system alerts the driver by flashing this
symbol in the instrument cluster and
sounding a chime.
Swerving vehicles
When a vehicle moves from an adjacent
lane into your lane, active cruise control will
not recognize this vehicle until it is fully in
your lane ahead of your vehicle.
Malfunctions
The build-up of foreign material, e. g.,
snow, ice, dirt, road debris, etc., can lead
to reduced detection performance of active
cruise control. You should check the sen-
sor under the front bumper and clean it as
necessary prior to driving your vehicle.
If the sensor becomes covered by foreign
material or has a malfunction, it is possible
that the sensor will no longer be able to
detect vehicles in front of you. After the
system recognizes that the sensor is no
longer functional, a message is displayed in
the Check Control and an acoustic signal is
emitted, refer to page83. Also observe the
additional information provided in the Con-
trol Center.

Ice warning
A warning signal sounds when the outside
temperature falls to roughly +37.57/+36,
this is accompanied by a message in the
Check Control.
Please bear in mind that the ice warn-
ing does nothing to alter the fact that
glare ice may be present on roads at tem-
peratures higher than +37.57/+36, for
instance, on bridges and shaded sur-
faces.<

moves upward as the engine warms to its
normal operating temperature. The seg-
ments disappear in sequence as the engine
warms to its normal operating temperature.
Avoid allowing the engine speed to rise as
far as the orange warning sector whenever
possible.

Fuel gauge
The fuel gauge mode appears automati-
cally once the fuel level falls into the
reserve range. At the same time, the words
"Fuel reserve" appear. The tank still con-
tains approx. 2.6 gallons/10 liters of fuel.
If the tilt of the vehicle varies, when you are
driving in mountainous areas, for example,
the indicator may fluctuate slightly.
It will not be possible to cancel the
computer display once the fuel level
drops into the reserve range. However, you
can still request a display of the travel
range. Computer, refer to page85.<
Fuel tank capacity: approx. 23.2 gallons/
88 liters. You can find information on refu-
eling on page186.
Refuel well before the tank is empty,
as otherwise engine functions will not
be ensured and damage can occur if you
drive down to the last drop.<
Cruising range
Displays the estimated cruising range avail-
able with the remaining fuel. The fuel level
is measured and the range is calculated
taking the driving style over the last
20 miles/30 km into account.
Always refuel as soon as possible
once your range falls to below
30 miles/50 km, as otherwise engine func-tions are not ensured and damage can
occur.<
Refueling is only registered by the com-
puter for fuel amounts above approx.
1.3 gallons/5 liters.
Remaining distance
When you enter a destination in the naviga-
tion system or manually enter a distance in
the computer prior to departure, the system
can also display the distance remaining to
your destination, refer to page132 or87.
The system automatically applies the dis-
tance to your destination using the route
recommended by the navigation system.
When you enter a destination in the
navigation system, any manual entries
will be overwritten no later than once
1,640 ft/500 meters of the calculated dis-
tance have elapsed.<
Energy Control/
current fuel consumption
Shows the current fuel consumption. This
allows you to see whether your current
driving style is conducive to fuel economy
with minimum exhaust emissions.
Average fuel consumption
The average fuel consumption is calculated
for the time during which the engine is run-
ning.
You can use the Control Display to view
your fuel consumption rate over two differ-
ent distances, refer to Computer or Trip
computer.
Average speed
Periods with the vehicle parked and the
engine off are not included in the calcula-
tions of average speed.
Reset average speed: Press button2 in the
turn indicator lever for approx. 2 seconds.
