2016 MERCEDES-BENZ CLA COUPE fuel

The ECO display consists of three sections, with
an inner and outer area. The sections corre-
spond to the following three categories: :
Acceleration
(evaluation of the
acceleration processes):
R the outer area fills up and the inner
area lights up green: moderate
acceleration, especially at higher
speeds
R the outer area empties and the
inner area is grey: sporty acceler-
ation ;
Coasting
(evaluation of all decelera-
tion processes):
R the outer area fills up and the inner
area lights up green: anticipatory
driving, keeping your distance and
early release of the accelerator.
The vehicle can coast without use
of the brakes.
R the outer area empties and the
inner area is grey: frequent heavy
braking =
Constant
(continuous evaluation
over the entire journey):
R the outer area fills up and the inner
area lights up green: constant
speed and avoidance of unneces-
sary acceleration and deceleration
R the outer area empties and the
inner area is grey: fluctuations in
speed The three inner areas display the current driving
style and light up green as a result of a particu-
larly economical driving style. Depending on the driving situation, up to two areas may light up
simultaneously.
At the beginning of the journey, the three outer
areas are empty and fill up as a result of eco-
nomical driving. A higher level indicates a more
economical driving style. If the three outer areas
are completely filled at the same time, the driver
has adopted the most economical driving style
for the selected settings and prevailing condi-
tions. The ECO display border lights up.
The ECO display does not indicate the actual fuel consumption. The additionally achieved range
displayed under Bonus from start
Bonus from start does not
indicate a fixed consumption reduction. In addition to driving style, the actual consump-
tion is affected by other factors, such as:
R load
R tyre pressure
R cold start
R choice of route
R the use of electrical consumers
These factors are not included in the ECO dis-
play.
An economical driving style involves driving at a moderate engine speed.
To achieve a higher value in the categories
"Acceleration" and "Constant":
R observe the gearshift recommendation.
R drive the vehicle in drive program Cor E
(vehicles with DYNAMIC SELECT button).
On long journeys at a constant speed, e.g. on the motorway, only the outer area for "Constant"
will change.
The ECO display summarises the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer areas at the start of a journey. During
a prolonged driving time, these changes are
smaller. For more marked changes, perform a
manual reset (Y page 204).

Important safety notes 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.
Downhill gradients Change into a lower gear in good time on long
and steep downhill gradients. For vehicles with
automatic transmission, you need to activate
manual gearshifting beforehand (Y page 150).160
Driving tipsDriving and parking

not exceed the maximum permissible speed for
your vehicle/trailer combination. Notes on towing a trailer
General notes Trailer towing is not possible on the following
models:
R CLA 180 d BlueEFFICIENCY Edition
R CLA 250 Sport
R CLA 250 Sport 4MATIC
R Mercedes‑AMG CLA 45 4MATIC
When towing a trailer, set the tyre pressure on
the rear axle of the towing vehicle for the max-
imum load. Further information on the tyre pres-
sure table in the fuel filler flap (Y page 313).
Please note that when towing a trailer, the fol-
lowing driving systems have limited availability
or are not available at all.
R Parking Assist PARKTRONIC (Y page 177)
R Blind Spot Assist (Y page 192)
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 334).
Driving tips Observe the notes on ESP
®
trailer stabilisation
(Y page 72).
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 maximum
permitted speed is. Observe the legally prescri-
bed maximum speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum 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 to when driving
without a trailer and the vehicle will consume
more fuel.
Shift into a lower gear in good time on long and steep downhill gradients. For vehicles with auto-
matic transmission, you need to have selected
manual drive program M(Y page 150).
This also applies if you have activated cruise
control, SPEEDTRONIC or Distance Pilot
DISTRONIC.
This will use the braking effect of the engine, so
less braking will be required to maintain the
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 pro-
gram Mis temporarily activated (vehicles with
automatic transmission): the automatic trans-
mission may switch back to the last active auto-
matic drive program Eor S. The automatic trans-
mission may shift to a higher gear. This can
reduce the engine's braking effect.
Driving tips R
Maintain a greater distance to the vehicle in
front than when driving without a trailer.
R Avoid braking abruptly. If possible, brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
R The values given for gradient-climbing capa-
bilities from a standstill refer to sea level.
When driving in mountainous areas, note that
the power output of the engine, and conse-
quently the vehicle's gradient-climbing capa-
bility from a standstill, decrease with increas-
ing altitude.
If the trailer swings from side to side:
X Do not accelerate under any circumstances
X Do not countersteer
X Brake, if necessary 196
