2012 MERCEDES-BENZ CLS SHOOTING BRAKE park assist

i
Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill start assist G
WARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal.N ever
leave the vehicle when it is held by hill start
assist.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient.
It holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and depress it before the vehicle begins to
roll.
X Take your foot off the brake pedal.
The vehicle is then held for about a second.
X Pull away.
Hill start assist will not function if:
R you are pulling away on a level road or a
downhill gradient.
R the transmission is in position N.
R the parking brake is applied.
R ESP ®
is malfunctioning. ECO start/stop function
Important safety notes G
WARNING
If the engine is switched off automatically and
you exit the vehicle, the engine is restarted
automatically. The vehicle may begin moving.
There is a risk of accident and injury. If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.
General notes :
ECO start/stop display
If the ¤ symbol appears in green in the
multifunction display, the ECO start/stop
function automatically switches the engine
off when the vehicle comes to a stop.
When pulling away again, the engine starts
automatically. The ECO start/stop function
thereby helps you to reduce the fuel con-
sumption and emissions of your vehicle.
Every time you switch on the engine using the
key or the Start/Stop button, the ECO start/
stop function is activated.
AMG vehicles: the ECO start/stop function
is only available in drive program C.
If the ECO start/stop function has been man-
ually deactivated (Y page 152) or if a mal-
function has caused the system to be deac-
tivated, the ¤symbol is not displayed.
AMG vehicles: theStop/Start active or
Stop/Start inactive display message
goes out in the AMG menu of the multifunc-
tion display.
Automatic engine switch-off Method of operation
If the vehicle is braked to a standstill in
Dor
N, the ECO start/stop function switches off
the engine automatically. 150

WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
ECO display
ECO display (example)
The ECO display gives you information on how
economical your driving style is. The ECO dis-
play assists you in achieving the optimum
driving style in terms of consumption, taking
the actual and selected conditions into con-
sideration. Your driving style can significantly
influence the vehicle's consumption.
The ECO display consists of three bars:
R
Acceleration
R Constant
R Coasting
The percen tvalue is the average value of the
three bars .The three bars and the average
value commence with a value of 50%. Ahigher
percentage indicates a mor eeconomical driv-
ing style.
The ECO display provides no information on
the actual fuel consumption. Afixed percent-
age value of the ECO display does not corre-
spond to a fixed consumption figure in
l/100km.
Apart from driving style, consumption is
dependent on many factors such as:
R load
R tyre pressure
R cold start
R selected route
R number of consumers that are switched on Driving tips

Driving with summer tyres
Observe the notes in the "Winte
roperation"
section (Y page 356).
Slippery road surfaces G
WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Move the transmission to position N.
X Try to bring the vehicle under control by
using corrective steering.
You should drive particularly carefully on slip-
pery road surfaces .Avoid sudden accelera-
tion, steering and braking manoeuvres.

snow chains, see (Y page 357). Driving systems
Cruise control
Important safety notes G
WARNING
Do not change downf or additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated. Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time.
G
WARNING
Do not use cruise control
R in traffic conditions that do not allow you to
drive at a constant speed (e.g. heavy traffic
or winding roads). You may otherwise
cause an accident.
R on slippery roads. The drive wheels may
lose their grip when braking or accelerating
and the vehicle may skid.
R when there is low visibility, e.g. due to fog,
heavy rain or snow.
General notes Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer (CLS Shoot-
ing Brake only), you must select shift range
1,
2 or 3in good time. By doing so, you will make
use of the braking effect of the engine. This
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 30 km/h. Driving systems

If cruise control is deactivated, you will hear
a warning tone. You will see the Cruisecontrol off message in the multifunction
display for approximately five seconds.
i The last speed stored is cleared when you
switch off the engine. SPEEDTRONIC
Important safety notes G
WARNING
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constan tslight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely. G
WARNING
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
WARNING
SPEEDTRONIC is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in good time.
SPEEDTRONIC brakes automatically so that
you do not exceed the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towin gatrailer (CLS Shoot-
ing Brake only), you must select shift range 1,
2 or 3in good time. By doing so, you will make
use of the braking effect of the engine .This
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly. If you need additional
braking, depress the brake pedal repeatedly
rather than continuously.
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. when driving with winter tyres
fitted (Y page 177)

Variable SPEEDTRONIC is deactivated auto-
matically if 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.
i The last speed stored is cleared when you
switch off the engine.
Permanent SPEEDTRONIC You can use the on-board computer to limit
the speed permanently to avalue between
160 km/h(e.g. for driving on winter tyres) and
the maximum speed ( Ypage 242).
Shortly before the store dspeed is reached, it
appears in the multifunction display.
Permanent SPEEDTRONIC remains active,
even if variable SPEEDTRONIC is deactivated.
You cannot exceed the stored limit speed,
even if you depress the accelerator pedal
beyond the pressure point (kickdown). DISTRONIC PLUS
Important safety notes G
WARNING
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
WARNING
DISTRONIC PLUS is only an aid designed to
assist driving. The driver remains fully respon-
sible for the vehicle's distance from other
vehicles, the vehicle's speed and for braking
in good time. DISTRONIC PLUS does not react in particular
to:
R
pedestrians
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic
DISTRONIC PLUS may not detect narro wvehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on a differen tline. Therefore,
always pay attention to traffic conditions even
when DISTRONIC PLUS is activated. Other-
wise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others. G
WARNING
DISTRONIC PLUS cannot tak eaccount of road
and traffic conditions. If DISTRONIC doe snot
recognise or no longer recognises the vehicle
in front, do not activate DISTRONIC or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R on filter lanes
R when changing to a lane with faster moving
traffic
R in complex driving situations or where lanes
are diverted, e.g. at roadworks on a motor-
way
DISTRONIC PLUS otherwise maintains the
current speed set by you or accelerates up to
the set speed.
DISTRONIC PLUS cannot take account of
weather conditions. Deactivate, or do not
activate, DISTRONIC PLUS:
R if the roads are slippery, snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicle could
start to skid.
R if the sensors are dirty or there is poor vis-
ibility, e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when DISTRONIC PLUS is activated. Driving systems

Otherwise, you may fail to recognise dangers
in time, cause an accident and injure yourself
and others. G
WARNING
DISTRONIC PLUS brakes your vehicle up to a
maximum of 4 m/s 2
depending on its speed.
This corresponds to approximately 40% of
your vehicle's maximum braking power. You
must also apply the brakes yourselfift his
braking power is not sufficient.
If DISTRONIC PLUS detects a risk of collision
with avehicle in front, an intermittent warning
tone sounds. In addition, the ·distance
warning lamp in the instrument cluster lights
up. Brake to avoid a collision.
General notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the dis-
tance to the vehicle detected in front. DIS-
TRONIC PLUS brakes automatically so that
the set speed is not exceeded.
On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer
(CLS Shooting Brake only), you must select
shift range
1,2or 3in good time. By doing
so, you will make use of the braking effec tof
the engine .This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly.
If DISTRONIC PLUS detects a slower-moving
vehicle in front, your vehicle is braked in order
to maintain the preset distance to the vehicle
in front.
If you want DISTRONIC PLUS to assist you,
the radar sensor system must be activated
(Y page 243) and operational.
The radar sensor system is switched off auto-
matically in the vicinity of radio telescope
facilities (Y page 398).
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control in the speed range between
30 km/h and 200 km/h. If avehicle is driving in front of you, DISTRONIC operates in the
speed range between 0km/h and
200 km/h.
Do not use DISTRONIC PLUS on roads with
steep gradients.

Pulling away and driving G
WARNING
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
DISTRONIC PLUS the nno longer brakes your
vehicle. In such cases, control the distance
from vehicles travelling in front with the brake
alone. You could otherwise cause an accident
and thereby injure yourself and others. The
driver remains fully responsible for the vehi-
cle's distance from other vehicles, the speed
being driven and for braking in good time.
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 press it up :or down =.
or
X Accelerate briefly.
Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control.
If DISTRONIC PLUS detects that the vehicle
in front has slowed down, it brakes your vehi-
cle. In this way, the distance you have selec-
ted is maintained.
If DISTRONIC PLUS detects that the vehicle
in front is driving faster, it accelerates your
vehicle, but only up to the speed you have
stored.
Changing lanes G
WARNING
DISTRONIC PLUS and Active Blind Spot Assist
are only an aid designed to assist driving.
They do not relieve you of the responsibility
of paying attention. The driver remains fully
responsible for the vehicle's distance from other vehicles, the vehicle's speed and for
braking in good time. Always pay attention to
traffic conditions and your surroundings. Oth-
erwise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others.
If you change to the overtaking lane, DIS-
TRONIC PLUS supports you if:
R you are driving faster than 60 km/h.
R DISTRONIC PLUS is maintaining the dis-
tance to a vehicle in front.
R you switch on the respective turn signals.
R DISTRONIC PLUS does not detect a danger
of collision.
If these conditions are met, your vehicle is
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in
front becomes too small.
i When changing lanes, DISTRONIC PLUS
monitors the left lane for left-hand-drive
vehicles and the right lane for right-hand-
drive vehicles.
Vehicles with COMAND Online
i The following function is not operational
in all countries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can
react appropriately to certain traffic situa-
tions. This is the case if, while following a
vehicle, DISTRONIC PLUS is active and you:
R approach or drive around a roundabout
R approach a T-junction
R turn off at a motorway exit
Even if the vehicle in front leaves the detec-
tion range, DISTRONIC PLUS temporarily
maintains the current driving speed and does
not accelerate. This is based on the current
map data in the navigation system. 180
