2015 MERCEDES-BENZ CLA SHOOTING BRAKE cruise control

Selecting the drive program
DISTRONIC PLUS supports a sporty driving
style when you select the S+drive program
(Mercedes-AMG vehicles only), S
(Y page 183) or the manual drive program
(Y page 185). Acceleration behind the vehicle
in front or to the set speed is then noticeably
more dynamic. If you have selected the E(C in
Mercedes-AMG vehicles:) drive program, the
vehicle accelerates more gently. This setting
is recommended in stop-start traffic.
Changing lanes
If you change to the overtaking lane,
DISTRONIC PLUS supports you if:
R you are driving faster than 70 km/h
R DISTRONIC PLUS is maintaining the dis-
tance to a vehicle in front
R you switch on the respective turn signal
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.
Stopping G
WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
R there is a malfunction in the system or in
the voltage supply.
R DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle.
R the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
R the battery is disconnected.
R the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident. If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
Further information on deactivating
DISTRONIC PLUS (Y page 209).
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 short period, the vehicle is secured
by the electric parking brake, thus relieving
the service brake.
i Depending on the specified minimum dis-
tance, your vehicle will come to a standstill
at a sufficient distance behind the vehicle in front. The specified minimum distance is
set using the control on the cruise control
lever.
When DISTRONIC PLUS is activated, the
transmission is shifted automatically to posi-
tion Pif:
R the driver's seat belt is not fastened and the
driver's door is open
R the engine is switched off, unless it is auto-
matically switched off by the ECO start/
stop function
The electric parking brake secures the vehicle automatically if DISTRONIC PLUS is activated
when the vehicle is stationary and:
R a system fault occurs
R the power supply is insufficient
If a malfunction in the electric parking brake
occurs, then the transmission may also be
shifted into position Pautomatically. Driving systems

Setting a speed
Bear in mind that it may take a brief moment
until the vehicle has accelerated or braked tothe set speed.
X Press the cruise control lever up :for a
higher speed or down ;for 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.
X To adjust the set speed in 1 km/h incre-
ments: briefly press the cruise control
lever up :or down ;to the pressure
point.
The last stored speed increases or decrea- ses in 1 km/h increments.

increments: press the cruise control lever
briefly up :or down ;beyond the pres-
sure point.
The last stored speed increases or decrea- ses in 10 km/h increments.
i DISTRONIC PLUS is not deactivated if you
depress the accelerator pedal. If you accel-
erate to overtake, DISTRONIC PLUS
adjusts the vehicle's speed to the last
speed stored after you have finished over-
taking. Setting the specified minimum distance 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 maintains to the vehicle in
front, dependent on vehicle speed. You can
see this distance in the multifunction display
(Y page 209).
i Make sure that you maintain the mini-
mum distance to the vehicle in front as
required by law. Adjust the distance to the
vehicle in front if necessary. X
To increase: turn control=in direc-
tion ;.
DISTRONIC PLUS then maintains a greater distance between your vehicle and the
vehicle in front.
X To decrease: turn control=in direc-
tion :.
DISTRONIC PLUS then maintains a shorter
distance between your vehicle and the
vehicle in front. 208

Tips for driving with DISTRONIC PLUS General notes
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 vehi-
cles when cornering is limited. Your vehicle
may brake unexpectedly or late.
Vehicles which are not driving in the mid- dle of their lane DISTRONIC PLUS may not detect vehicles
which are not driving in the middle of their
lane. The distance to the vehicle in front will
be too short. 210

Notes on towing a trailer
General notes Trailer towing is not permissible on the fol-
lowing models:
R
Mercedes‑ AMG CLA 45 4MATIC
R Vehicles with AMG Line
When towing a trailer, set the tyre pressure on
the rear axle of the towing vehicle for the
maximum load. Further information on the
tyre pressure table in the fuel filler flap
(Y page 374).
Please note that when towing a trailer, the
following driving systems have limited avail-
ability or are not available at all.
R PARKTRONIC (Y page 216)
R Blind Spot Assist (Y page 234)
The height of the ball coupling changes with
the load of the vehicle. If necessary, use a
trailer with a height-adjustable drawbar.
You will find fitting dimensions and loads
under "Technical data" (Y page 411).
Driving tips Observe the notes on ESP
®
trailer stabilisa-
tion (Y page 79).
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check
the trailer's documents to see what the max- imum permitted speed is. Observe the legally
prescribed maximum speed in the relevant
country.
For certain Mercedes-Benz vehicles, the max-
imum permissible rear axle load is increased
when towing a trailer. See the "Technical
data" section to find out whether this applies to your vehicle. If you utilise any of the added
maximum rear axle load when towing a trailer, the vehicle/trailer combination may not
exceed a maximum speed of 100 km/h for
reasons concerning the operating permit.
This also applies in countries in which the permissible maximum speed for vehicle/
trailer combinations is above 100 km/h.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison to when driving without a trailer and it will
consume more fuel.
Change into a lower gear in good time on long
and steep downhill gradients. For vehicles
with automatic transmission, you need to
have selected manual drive program M
(Y page 185).
This also applies if you have activated cruise
control, SPEEDTRONIC or DISTRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to maintain
vehicle speed. 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.
Briefly depressing the accelerator pedal on
downhill gradients while the manual drive
program Mis temporarily activated (vehicles
with automatic transmission): the automatic
transmission may switch back to the last
active automatic drive program Eor S. The
automatic transmission may shift to a higher
gear. This can reduce the engine's braking
effect.
Driving tips If the trailer swings from side to side:
X Do not accelerate.
X Do not countersteer.
X Brake if necessary.
R Maintain a greater distance to the vehicle in
front than when driving without a trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then, increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from a standstill refer to sea
level. When driving in mountainous areas,
note that the power output of the engine,
and consequently the vehicle's gradient- Towing a trailer
