As with conventional cruise control systems, ac‐
tive cruise control in no way reduces or substi‐
tutes for the driver's own personal experience,
responsibility, alertness and awareness in ad‐
justing speed, braking or otherwise controlling
the vehicle. The driver should decide when to
use the system on the basis of road, traffic, vis‐
ibility, and weather conditions. Active cruise
control is intended for use on highway-type
roadways where traffic is moving relatively
smoothly as well as in slow-moving traffic con‐
gestion.
Do not use the system in city driving; in
complex driving situations; 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 enter‐
ing interchanges, service/parking areas or toll
booths. It is also important to regulate your ve‐
hicle's speed and distance setting within appli‐
cable 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. Otherwise, driving conditions can result
which lead to a violation of the law or elevated
risk of an accident.
The minimum initial activation speed is
20 mph/ 30 km/h, and the maximum speed is
110 mph/ 180 km/h. The system can also be ac‐
tivated while the vehicle is stationary, refer to
page 105.

Storing the current speed
Push
the lever, arrow 1, or pull it briefly, arrow 2. The system stores the current vehicle speed. It
is indicated on the speedometer and briefly in
the instrument panel.
Increasing desired speed
Press or briefly push the lever up to or beyond
the resistance point, arrow 1, until the desired
speed is displayed.
The displayed speed is stored and the vehicle
reaches the stored speed if the road is clear.
▷
With each activation to the resistance point,
the desired speed increases by approx.
1 mph/1 km/h.
▷ With each activation beyond the resistance
point,
the desired speed increases by a max‐
imum of 5 mph/10 km/h.
Reducing the desired speed
Pull
the lever, arrow 2, until the desired speed is
displayed.
The functions are the same as those when in‐
creasing the desired speed.

the bend of the curve. Any deceleration of the
vehicle by the system can be compensated for
by briefly accelerating. After the accelerator
pedal is released, the system becomes active
again and independently controls the speed.
Driving away
In some situations, the vehicle cannot drive
away automatically, e.g., on steep inclines, with
a heavy trailer or behind bumps in the road.
Driver interventions and your
responsibility
Your
actions have priority at all times. When you
press on the accelerator pedal while driving, au‐
tomatic braking is not performed and the bars in
the distance display go out until you lift your foot
from the accelerator pedal. Once you release the
accelerator pedal, the desired speed is achieved
again on clear roads or the selected distance to
the vehicle ahead is maintained.
Making braking possible
Anytime the driver presses down on the
accelerator pedal, any braking action by the sys‐
tem is interrupted and the distance indicator
goes out until the pedal is fully released. As soon
as you fully release the accelerator, the system
will again control your cruising speed and dis‐
tance setting. While driving with the system ac‐
tivated, resting your foot on the acelerator pedal
will cause the system not to brake even if nec‐
essary. Be certain that floormats or other ob‐
jects on the vehicle floor do not interfere with
movement of the acccelerator pedal.◀
Limits of automatic braking
While active cruise control is capable of
braking your vehicle automatically when you ap‐
proach a slower vehicle ahead, it is important to
be aware that the ability of the system to apply
the brakes is also limited, e.g. when you reduce
your desired speed sharply. lt uses only a portion
of braking 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: when you approach a vehicle traveling at a much
lower speed than your own speed such as ap‐
proaching a toll booth or when a much slower
vehicle cuts in front of you at close range.◀
Cruise control*
The concept
The
system is functional at speeds beginning at
approx. 20 mph/30 km/h.
The speed specified using the lever on the
steering column is maintained.
The system brakes on downhill gradients if en‐
gine braking action is insufficient.
Do not use cruise control
Do not use the system if unfavorable con‐
ditions make it impossible to drive at a constant
speed, for instance:
▷ On curvy roads.
▷ In heavy traffic.
▷ On slippery roads, in fog, snow or rain, or on
a loose road surface.
Otherwise, you could lose control of the vehicle
and cause an accident.◀
