2008 MERCEDES-BENZ CLS COUPE brake

Driving systems
142 Speedtronic
Speedtronic brakes automatically so that you
do not exceed the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select shift range
1, 2 or 3 in good time. In this way you will
make use of the braking effect of the engine,
which relieves the load on the brake system
and prevents the brakes from overheating
and wearing too quickly. If you need addi-
tional braking, depress the brake pedal
repeatedly rather than continuously. G
Risk of accident
Never depress the brake pedal continu-
ously 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 144) 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, Distronic* 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* 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. 1

Variable Speedtronic is deactivated automat-
ically when you depress the accelerator pedal
beyond the pressure point (kickdown). but
only if your current speed does not differ by
more than 20 km/h from the stored speed.
You will hear a warning tone if this is the case.
G
Risk of accident
It is not possible to deactivate variable
Speedtronic by braking.
i The last speed stored is cleared when you
switch off the engine.
Permanent Speedtronic i
Permanent Speedtronic is only available
for certain countries.
You can use the on-board computer to limit
the speed permanently to a value between
160 km/h (e.g. for driving with winter tyres)
and the maximum speed.
Shortly before the stored speed is reached, it
is shown in the multi-function display.
You cannot exceed the stored limit speed,
even if you depress the accelerator pedal
beyond the pressure point (kickdown). Setting permanent Speedtronic

Activating HOLD X
Make sure that the activation conditions
are met.
X Depress the brake.
X Depress the brake again quickly until
HOLD appears in the display.
HOLD is activated. You can release the
brake pedal.
i If depressing the brake pedal the first
time does not activate HOLD, wait briefly
and then try again. G
Risk of accident
The vehicle's brakes are applied when
HOLD is activated. For this reason, deacti-
vate HOLD if the vehicle is to be set in
motion by other means (e.g. in a car wash
or by towing).
Deactivating HOLD HOLD is deactivated if:
R
you
accelerate when the selector lever is in
position D or R
R you move the selector lever to position P
R you release the brakes completely and
apply them again with a certain amount of pressure until the
HOLD message in the
multi-function display goes out G
Risk of accident
Never get out of the vehicle when HOLD is
activated.
HOLD

must never be operated or deactiva-
ted by a passenger or from outside the
vehicle.
HOLD does not replace the parking brake
and must not be used for parking.
The HOLD braking effect is cancelled and
the vehicle can start moving if:
R HOLD is deactivated by depressing the
accelerator pedal or the brake pedal
R there is a malfunction in the system or an
interruption in the power supply, e.g. bat-
tery failure
R the electrical system in the engine com-
partment, the battery or the fuses are
tampered with
R the battery is disconnected G
Risk of accident
If you wish to leave the vehicle or park it,
deactivate HOLD and secure the vehicle
against rolling away. You will see a warning message in the multi-
function display if HOLD is activated and:
R
the

driver's door is opened and you release
the seat belt
R the ignition is switched off

HOLD is deactivated. The warning message
in the multi-function display goes out.
A horn will also sound at regular intervals if
HOLD is activated and you:
R stop

the engine and open the driver's door
R open the bonnet
The horn draws your attention to the fact that
the vehicle has been parked while HOLD is
still activated. The sound becomes louder if
you attempt to lock the vehicle. The vehicle
is not locked until HOLD is deactivated.
i If the ignition has been switched off, the
engine cannot be restarted until HOLD is
deactivated.

148 Parktronic*
G
Risk of accident
Parktronic is only an aid and may not detect
all obstacles. It does not relieve you of the
responsibility to pay attention.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
manoeuvring. You could otherwise endan-
ger yourself and others. G
Risk of injury
Make sure that no persons or animals are
in the manoeuvring range. Otherwise, they
could be injured.
Parktronic is an electronic parking aid. It indi-
cates visually and audibly the distance
between your vehicle and an object.
Parktronic is automatically activated when
you switch on the ignition and release the
parking brake.
Parktronic is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
Parktronic monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.1 Sensors in the front bumper
Range of the sensors
The sensors must be free of dirt, ice and
slush, otherwise they may not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them.
