Things to know about active cruise control
As with conventional cruise control
systems, active cruise control in no
way diminishes or substitutes for the
driverÕs own personal responsibility, alert-
ness and awareness in adjusting speed,
braking or otherwise controlling the vehi-
cle. The driver should decide when to use
the system on the basis of road, traffic,
visibility, and weather conditions. Active
cruise control is intended for use on high-
way-type roadways where traffic is moving
relatively smoothly. Do not use this system
in city driving; heavy traffic such as during
rush hour; on curvy, winding roads, slip-
pery roads or roads with sharp curves such
as highway off-ramps; during inclement
weather such as snow, strong rain or fog;
or when entering interchanges, service/
parking areas or toll booths. It is also
important to regulate your vehicle's speed
and distance setting within applicable legal
limits. Always be ready to take action or
apply the brakes if necessary, especially
when the system is actively following a
vehicle in front of you.<
Always remember that the range and
ability of the system does have phys-
ical limitations. It will not apply the brakes
or decelerate your vehicle when there is a
slow-moving vehicle, stopped vehicle or
stationary object ahead of you, as for
example, at a traffic light or a parked vehi-
cle. Also, the system does not react to
oncoming traffic, pedestrians or other type
of potential traffic such as a rider on horse-
back. It is also possible that the system
may not detect smaller moving objects
such as motorcycles or bicycles. Be espe-
cially alert when encountering any of these situations as the system will neither auto-
matically 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 alert-
ness.<
If while 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 vehicle will
accelerate to the speed you have selected.
Be aware that changing to a clear, unob-
structed 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 man-
ner 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 system 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 deactivated whenever the driver applies
the vehicle brakes, shifts the transmission
from drive/D to neutral/N, or deactivates
DSC. After any deactivation, the system
will no longer automatically activate the

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 Ð e.g.,
snow, ice, dirt, road debris, etc. Ð 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 page 82. Also observe
the additional information provided in the
Control Center.

Fuel gauge
The fuel gauge display 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.
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 page 84.<
Tank capacity: approx. 23.2 gallons/
88 liters. You can find information on refu-
eling on page 186.
If the tilt of the vehicle varies, when you are
driving in mountainous areas, for example,
the indicator may fluctuate slightly.
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
available with the remaining fuel. The sys-
tem calculates the cruising range based on
operating conditions and the amount of fuel
remaining in the tank. The basis for the cal-
culations is the average fuel consumption
over the preceding 20 miles/30 km.
Always refuel as soon as possible
once your range falls to below
30 miles/50 kilometers, as otherwise
engine functions are not ensured and dam-
age 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 sys-
tem can also display the distance remain-ing to your destination, refer to page 132
or 86.
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
distance 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.
Time of arrival
A display of your estimated time of arrival is
available whenever you enter a destination
in the navigation system, refer to page 132,
or enter the distance manually in the com-
puter, refer to page 86, prior to departure.
A requirement is that you have cor-
rectly set the time in the Control Cen-
ter, refer to page 88.<
