2009 MERCEDES-BENZ CL COUPE cruise control

Activating when driving towards a sta-
tionary vehicle
If the vehicle in front of you is stationary, you
can only activate Distronic Plus once your
vehicle is stationary as well.
X Briefly pull the cruise control lever towards
you ?.
Distronic Plus is selected.
i Distronic Plus can only be activated at
under 30 km/h if a vehicle in front has been
detected. Therefore, the Distronic Plus dis-
tance display in the instrument cluster
should be activated.
X Keep the cruise control lever pressed
up : or down Auntil the desired speed
is set.
i You can use the cruise control lever to set
the stored speed and the thumbwheel on
the cruise control lever to set the specified
minimum distance (Y page 239).
Pulling away
X If the vehicle in front pulls away: remove
your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you ?.
or
X Accelerate briefly.
Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
Driving
If there is no vehicle in front, Distronic Plus
operates in the same way as cruise control.
If a slower-moving vehicle is detected in front,
Distronic Plus causes your vehicle to brake
and maintain a preset distance to the vehicle
in front.
If Distronic Plus detects a faster-moving vehi-
cle in front, it increases the driving speed, but
only up to the stored speed. G
Risk of accident
If you depress the brake, Distronic Plus is
deactivated unless your vehicle is stationary.
Distronic Plus then no longer brakes your
vehicle. The driver remains fully responsible
for the vehicle's distance from other vehicles,
its speed and for braking in good time.
Stopping G
Risk of accident
The Distronic Plus braking effect is cancelled
and the vehicle could roll away if:
R Distronic Plus is deactivated using the
cruise control lever.
R you accelerate.
R the system or the power supply is disrup-
ted, e.g. due to battery failure.
R the electrical system in the engine com-
partment or the fuses have been tampered
with.
R the battery is disconnected. G
Risk of accident
Never get out of the vehicle when Distronic
Plus is activated.
Distronic Plus must never be operated or
deactivated by a passenger or from outside
the vehicle.
Distronic Plus does not replace the electric
parking brake and must not be used for park-
ing.
If you wish to leave the vehicle or park it,
deactivate Distronic Plus and secure the vehi-
cle against rolling away.
If Distronic Plus detects that the vehicle in
front is stopping, it brakes your vehicle until
it is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
i After a time, the electric parking brake
secures the vehicle and relieves the service
brake. 238

Depending on the specified minimum dis-
tance, your vehicle will come to a standstill
about four metres behind the vehicle in
front. The specified minimum distance is
set using the thumbwheel on the cruise-
control lever.
Setting a speed X
Press the cruise control lever to the pres-
sure point, up :for a higher speed or
down Afor a lower speed.
X Keep the cruise control lever pressed until
the desired speed is reached.
X Release the cruise control lever.
The new speed is stored. Distronic Plus is
activated and adjusts the vehicle's speed
to the new speed stored.
Making adjustments in 1 km/h incre-
ments X
Briefly press the cruise control lever to the
pressure point, up :for a higher speed or
down Afor a lower speed.
The last speed stored is increased or
reduced.
Making adjustments in 10 km/h incre-
ments X
Briefly press the cruise control lever
beyond the pressure point, up :for a
higher speed or down Afor a lower speed.
The last speed stored is increased or
reduced.
Storing the current speed or calling up
the last stored speed G
Risk of accident
Only select a stored speed if you know what
that speed is and whether it is suitable for the
current situation. Otherwise, sudden acceler-
ation or braking could endanger you or others. X
Briefly pull the cruise control lever towards
you ?.
X Remove your foot from the accelerator
pedal.
Distronic Plus is activated. The first time it
is activated, the current speed is stored.
Otherwise, it sets the vehicle cruise speed
to the previously stored value.
Setting the specified minimum dis-
tance for Distronic Plus You can set the specified minimum distance
for Distronic Plus by varying the time span
between one and two seconds. With this func-
tion, you can set the minimum distance that
Distronic Plus keeps to the vehicle in front,
dependent on vehicle speed. You can read
this distance in the multi-function display
(Y
page 240). X
To increase: turn thumbwheel ;towards
=.
Then, Distronic Plus maintains a greater
distance between your vehicle and the
vehicle in front.
X To decrease: turn thumbwheel ;
towards :.
Then, Distronic Plus maintains a shorter
distance between your vehicle and the
vehicle in front.
i Make sure that you maintain the mini-
mum distance to the vehicle in front
required by law. Adjust the distance to the
vehicle in front if necessary. Driving systems

Deactivating Distronic Plus
There are several ways to deactivate Dis-
tronic Plus:
X
Briefly press the cruise control lever for-
wards :.
or
X Brake, unless the vehicle is stationary.
or
X Briefly press the cruise control lever in the
direction of arrow =.
Variable Speedtronic is selected. LIM indi-
cator lamp ;in the cruise control lever
lights up.
i The last speed stored remains stored until
you switch off the engine.
i Distronic Plus is not deactivated if you
depress the accelerator pedal. If you accel-
erate briefly to overtake, Distronic Plus
adjusts the vehicle's speed to the last
speed stored after you have finished over-
taking.
Distronic Plus is automatically deactivated if:
R you engage the electric parking brake or if
the vehicle is automatically secured with
the electric parking brake
R you are driving slower than 25 km/h and
there is no vehicle in front, or the vehicle in
front is no longer detected
R ESP ®
intervenes or you deactivate ESP ®R
you shift the automatic transmission to N,
P or R
R the vehicle is near a radio telescope facility:
only vehicles with COMAND and a naviga-
tion system* (Y page 411).
If Distronic Plus is deactivated, you will hear
a warning tone. You will see the DISTRONIC
PLUS off message in the multi-function dis-
play for approximately five seconds
Tips for driving with Distronic Plus The following contains descriptions of certain
road and traffic conditions in which you must
be particularly attentive. In such situations,
brake if necessary. Distronic Plus is then
deactivated.
Cornering, entering and exiting a bend The ability of Distronic Plus to detect vehicles
when cornering is limited. Your vehicle may
brake unexpectedly or too late.

tional braking, depress the brake pedal
repeatedly rather than continuously.
G
Risk of accident
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
You can set a variable or permanent limit
speed:
R variable for speed limits, e.g. in built-up
areas
R permanent for long-term speed restric-
tions, e.g. for driving on winter tyres
(Y page 245) G
Risk of accident
Speedtronic is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time.
i The speed indicated in the speedometer
may differ slightly from the limit speed
stored.
Variable Speedtronic With the cruise control lever, you can operate
cruise control or Distronic*/Distronic Plus*
and variable Speedtronic.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:
R LIM indicator lamp off:
Cruise control or Distronic*/Distronic
Plus* is selected.
R LIM indicator lamp lit: Variable Speedtronic is selected.
You can use the cruise control lever to limit
the speed to any speed above 30 km/h while
the engine is running. :

Driving tips
Rolling with the engine switched off
G
Risk of accident
Never switch the engine off while the vehicle
is in motion.
There is no power assistance for the steering
and the service brake when the engine is not
running.
You will require considerably more effort to
steer and brake and you could therefore lose
control of the vehicle and cause an accident. Brakes
G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
Risk of accident
Make sure that other road users are not
endangered by your braking.
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden, you must select
shift range 1,2or 3in good time.
i This also applies if you have activated
cruise control, Speedtronic, Distronic* or
Distronic Plus*.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously.
Heavy and light loads If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but drive on for a short while. This allows the air-
flow to cool the brakes more quickly. G
Risk of accident
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet roads If driving in heavy rain for a prolonged period
of time without braking, there may be a
delayed reaction from the brakes when brak-
ing for the first time. You must brake harder.
You must therefore maintain a greater dis-
tance from the vehicle in front.
After driving on a wet surface, brake firmly
while paying attention to the traffic condi-
tions. This way the brake discs will become
warm, drying more quickly, which will protect
them against corrosion.
Limited braking performance on salted
roads G
Risk of accident
The layer of salt on the brake discs and the
brake pads/linings may cause a delay in the
braking effect, resulting in a significantly lon-
ger braking distance, which could lead to an
accident.
To avoid this danger, you should:
R occasionally brake carefully, without put-
ting other road users at risk, when you are
driving on salted roads. This helps to
remove any salt that may have started to 304
