Driving
72 your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead
of you, as for example at a traffic light or when
approaching a parked vehicle. Also, the system
does not react to oncoming traffic, pedestrians
or other types of potential traffic such as a rider
on horseback. It is also possible that the system
may not detect smaller moving objects such as
motorcycles or bicycles. Be especially alert
when encountering any of these situations as
the system will neither automatically brake, nor
provide a warning to you. Also, be aware that
every decrease in the distance setting allows
your vehicle to come closer to a vehicle in front
of you and requires a heightened amount of
alertness.<
If your vehicle is actively following a vehicle in
front of you and the vehicle ahead speeds up or
the lane ahead becomes clear, then your vehi-
cle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane will also result in your vehicle
accelerating.
Be certain to deactivate the system when
you pull into an exit lane for a highway off-
ramp.<
Also, vehicles traveling in a staggered manner
on a highway may cause a delay in the system's
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
Active cruise control can only decelerate the
vehicle to approx. 20 mph/30 km/h. If the sys-
tem reduces vehicle speed below 20 mph/
30 km/h or if DSC/ABS is engaged while driving,
the system will automatically deactivate.
Remember, the system cannot stop your
vehicle. In addition, the system is deacti-
vated whenever the driver applies the vehicle
brakes, shifts into neutral, or deactivates DSC.
After any deactivation, the system will no longer
automatically activate the vehicle brakes, which
means the driver must intervene and resume
manual braking. You should then reactivate the
system only when you are fully aware of the
prior speed and distance settings.
driver must constantly monitor traffic and inter-
vene if necessary.
When you switch off the engine or ignition,
active cruise control is fully switched off, too,
and any settings you have selected are can-
celed.
Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, active cruise control will not rec-
ognize this vehicle until it is fully in your lane
ahead of your vehicle.
Behavior in curves
Because of the limited range of the system, it is
possible that in curves or on the peaks and val-
leys of hilly roads, a vehicle ahead may be rec-
ognized late, or not at all. Therefore, it is up to
the driver to select a speed that is prudent in
view of the curves and terrain of the roadway.

Outside temperature warning
If the display drops to +377/+36, a signal
sounds and a message appears. There is an
increased danger of ice.
Ice can form even at temperatures above
+377/+36. Drive carefully, especially
on bridges and shaded roadways; otherwise,
your risk of accident increases.<
Tachometer
The white-striped advance warning field,
arrow1, changes depending on the engine
temperature. The segments disappear in
sequence as the engine warms to its normal
operating temperature.
Avoid allowing the engine speed to rise as far as
the advance warning field whenever possible.
It is absolutely crucial to avoid engine speeds in
the red warning field, arrow2.
In this range, the fuel supply is interrupted to
protect the engine.
Coolant temperature
Should the coolant and therefore the engine
become too hot, a warning lamp lights up. In
addition, a message appears on the Control
Display.
Checking coolant level, refer to page193.

Engine oil temperature gauge
During normal operation, the engine oil temper-
ature is between approx. 1607/706 and
approx. 3407/1706.
If the engine oil temperature is too high, a mes-
sage appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 18.5 gallons/
70 liters. You can find information on refueling
on page182.
If the tilt of the vehicle varies for a longer period,
for example when you are driving in mountain-
ous areas, the indicator may fluctuate slightly.
Reserve
After the reserve quantity has been reached, a
message appears for a short time on the Con-
trol Display; the remaining range is shown in the
onboard computer. Below a range of approx.
30 miles/50 km, the message remains on the
Control Display.
Refuel as soon as possible once your
remaining range falls below 30 miles/

Average fuel consumption
The average fuel consumption is calculated for
the time during which the engine is running.
You can use the Control Display to view your

Check Control
The concept
The Check Control monitors functions in the
vehicle and issues a message if there is a mal-
function in the monitored systems. A Check
Control message of this kind includes indicator
or warning lamps in the instrument cluster, pos-
sibly an acoustic signal, and text messages at
the bottom of the Control Display.
Indicator and warning lamps
Indicator and warning lamps can light up in dif-
ferent combinations and colors, both in the dis-
play area1 and in the display2
This symbol means that a Check Control
message has been generated. The symbol
remains visible even if the Check Control message has been hidden after a short time.
The combinations of warning lamps and text
messages are stored and can be viewed later,
also refer to page80.
Explanatory text messages
Text messages at the bottom edge of the Con-
trol Display explain the meaning of the indicator
and warning lamps displayed.
You can display supplementary information
regarding most Check Control messages, e.g.
as to the cause of a malfunction and corre-
sponding actions to be taken, see below.
In cases of corresponding urgency, this infor-
mation is immediately displayed when the
associated lamps light up.
To exit the displayed information:
Select the arrow and press the controller.
Importance of Check Control
messages
Important Check Control messages are
retained until the malfunctions have been recti-
