All indicator and warning lamps as well as dis-
plays in the instrument cluster go out.
Starting the engine
Do not run the engine in enclosed areas; 
otherwise, the inhalation of toxic exhaust 
gases can cause loss of consciousness and 
death. The exhaust gases contain carbon mon-
oxide, an odorless and colorless, but highly 
toxic gas. Never leave an unattended vehicle 
with the engine running; otherwise, such a vehi-
cle represents a potential safety hazard. 
Before leaving the car with the engine running, 
place the transmission in neutral or move the 
selector lever to position P and forcefully apply 
the parking brake to prevent the car from mov-
ing.<
Avoid frequent starting in quick succes-
sion as well as repeated start attempts in 
which the engine does not start. Otherwise, the 
fuel is not burned or incompletely burned and 
there is a danger of overheating and damaging 
the catalytic converter.<
Do not wait for the engine to warm up while the 
vehicle remains stationary. Start driving right 
away, but at moderate engine speeds.

tinuously press the button of the parking brake 
lever. 
Otherwise, excessive force on the parking 
brake can lock up the rear wheels and cause the 
rear of the car to swerve.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the parking 
brake lightly when the vehicle is slowly coming 
to a stop if the traffic conditions are suitable.The brake lamps do not light up when the park-
ing brake is applied.<

Cruise control*
The concept
Cruise control is available for use at speeds of 
approx. 20 mph or 30 km/h. The car then stores 
and maintains the speed that you specify using 
the lever on the steering column. In order to 
maintain the specified speed, the system 
brakes the vehicle when the engine braking 
effect is insufficient on downhill gradients.
Do not use cruise control when driving at 
constant speed is prevented by adverse 
conditions, e.g. winding roads, dense traffic or 
poor road conditions due to, e.g., snow, rain, ice 
or loose surfaces. Otherwise, you could lose 
control of the vehicle and cause an accident as a 
result.<
Manual transmission
You can shift gears while cruise control is acti-
vated. The system is deactivated when you 
drive at very low engine speeds for an extended 
period.

Maintaining current speed
Tap the lever, arrow 1, or pull it briefly, arrow 2.
The car's current speed is stored and main-
tained. It is displayed on the speedometer and 
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to 
maintain the set speed if current engine power 
output is insufficient. If the engine braking 
effect is insufficient on downhill slopes, the sys-
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance 
point or beyond, arrow1, until the desired 
speed is reached.
>Each time the lever is pressed to the resis-
tance point, the desired speed is increased 
by approx. 1 mph or 1 km/h.
>Each time the lever is pressed beyond the 
resistance point, the desired speed is 
increased by up to 5 mph or 10 km/h.
The system stores and maintains the speed.
Accelerating using the lever
Accelerating slightly:

maintained when driving on open roadways, but 
also varied to maintain a selected distance set-
ting as slower traffic is encountered.
Active cruise control is a technological advance 
over the familiar cruise control and is a welcome 
relief from the constant adjustment of speed 
that can accompany driving in traffic on high-
ways or other high-speed thoroughfares. Espe-
cially on longer trips, the system can reduce 
fatigue and tension, while increasing your 
enjoyment of driving. Please use it safely and 
responsibly.
Within the limits of its capability, the system 
automatically adapts the car's speed to that of a 
slower vehicle in front of you. You can specify 
the distance to be maintained from the vehicle 
in front in four stages. For safety reasons, the 
distance is speed-dependent. Based on your 
selected distance setting, the system automat-
ically decreases the throttle setting and lightly 
applies the brakes if necessary. The vehicle 
brake lamps will automatically illuminate to sig-
nal a following driver to take action. In addition, 
it may be necessary for the vehicle or the driver 
to downshift, depending on the kind of trans-
mission your vehicle is equipped with, to main-
tain the distance setting selected. If the vehicle 
ahead speeds up or when the lane ahead 
becomes clear, your vehicle will accelerate to 
the speed you have selected by increasing the 
throttle setting and shifting gears automatically 
or by the driver as needed. Your selected speed 
will be held when driving downhill, too.
Since this active cruise control system is a new 
technology and operates differently from con-
ventional cruise control systems which you may 
be accustomed to, you are strongly urged to 
read all of the pages relating to this system 
before use. Pay special attention to the System 
limitations section beginning on page66.
Braking sensation
>If you step on the brake pedal while the sys-
tem is braking, pedal sensation will be 
slightly different from the usual.
>Possible noises during automatic braking 
are normal.
Manual transmission
You can shift gears while cruise control is acti-
vated. The system is deactivated when you 
drive at very low engine speeds for an extended 
period.
Range of applications
The minimum desired speed is 20 mph or 
30 km/h, the maximum desired speed is 
110 mph or 180 km/h.
As with conventional cruise control sys-
tems, active cruise control in no way 
diminishes or substitutes for the driver’s own 
personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise 
controlling the vehicle. 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 
highway-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, slippery roads or 
roads with sharp curves such as highway off-
ramps; during inclement weather such as snow, 
strong rain or fog; or when entering inter-
changes, 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. Otherwise, driving situations could 
result that pose the risk of accidents.<
