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. Driving tips

Drive sensibly – save fuel
Observe the following tips to save fuel:
R The tyres should always be inflated to the
recommended tyre pressure.
R Remove unnecessary loads.
R Remove roof racks when they are not nee-
ded.
R Warm up the engine at low engine speeds.
R Avoid frequent acceleration or braking.
R Have all maintenance work carried out as
indicated by the service intervals in the
Service Booklet or by the service interval
display.
Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic, on
short journeys and in hilly terrain. ECO display
The ECO display shows you how economical
your driving style is. The ECO display assists
you in achieving the most economical driving
style for the selected settings and prevailing
conditions. Consumption can be significantly influenced by your driving style. :
Acceleration
; Coasting
= Constant
? Additional range achieved
Range ?is shown under Bonus fr. start Bonus fr. start
and represents the additional range achieved
since the beginning of the journey as a result of an adapted driving style.
If the fuel level has dropped into the reserve
range, the Reserve fuel Reserve fuel message is shown
in the multifunction display instead of
range ?. In addition, the 8warning lamp in the instrument cluster lights up
(Y
page 301).
The ECO display consists of three sections,
with an inner and outer area. The sections
correspond to the following three categories: :
Acceleration
(evaluation of all
acceleration processes):
R the outer area fills up and the
inner area lights up green: mod-
erate acceleration, especially at
higher speeds
R the outer area empties and the
inner area is grey: sporty accel-
eration ;
Coasting
(evaluation of all decel-
eration processes):
R the outer area fills up and the
inner area lights up green: antic-
ipatory driving, keeping your dis- tance 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: con-
stant speed and avoidance of
unnecessary acceleration and
deceleration
R the outer area empties and the
inner area is grey: fluctuations in
speed The three inner areas display the current driv-
ing style and light up green as a result of a
particularly 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 188

economical 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 eco-
nomical driving style for the selected settings and prevailing conditions. The ECO display
border lights up.
The ECO display does not indicate the actual
fuel consumption. The additionally achieved
range displayed under Bonus fr. start
Bonus fr. start
does not indicate a fixed consumption reduc- tion.
In addition to driving style, the actual con-
sumption 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 "con-
stant" 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. Dur-
ing a prolonged driving time, these changes
are smaller. For more marked changes, per-
form a manual reset (Y page 243).
Further information on the ECO display
(Y page 242). Brakes
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. Take particular note of this when driving a laden vehicle and
when towing a trailer. For vehicles with auto-
matic transmission, you need to activate
manual gearshifting (Y page 177).
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.
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.
Heavy and light loads G
WARNING
The braking system can overheat if you leave your foot on the brake pedal while driving.
This increases the braking distance and could
even cause the braking system to fail. There is
a risk of an accident. Driving tips

Cruise control is not deactivated if you
depress the accelerator pedal. For exam-
ple, if you accelerate briefly to overtake,
cruise control adjusts the vehicle's speed
to the last speed stored after you have fin- ished overtaking.
Deactivating cruise control There are several ways to deactivate cruise
control:
X Briefly press the cruise control lever for-
wards B.
or
X Brake.
or X Briefly press the cruise control lever in the
direction of arrow A.
Variable SPEEDTRONIC is selected. LIM
indicator lamp ;in the cruise control lever
lights up.
Cruise control is automatically deactivated if: R the vehicle is secured with the electric
parking brake
R you are driving at less than 30 km/h
R ESP ®
intervenes or you deactivate ESP ®
R while driving a vehicle with manual trans-
mission, you shift into neutral or depress
the clutch pedal for longer than six seconds
R on vehicles with manual transmission, you
shift to a gear that is too high, and as a
result the engine speed is too low
R on vehicles with automatic transmission,
you shift to position Nwhile driving
If cruise control is deactivated, you will hear a
warning tone. You will see the Cruise con‐
Cruise con‐
trol off trol off message in the multifunction dis-
play for approximately five seconds.
i The last speed stored is cleared when you
switch off the engine. SPEEDTRONIC
General notes SPEEDTRONIC brakes automatically so that
you do not exceed the set speed. You must
select a lower gear in good time on long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer. For vehi-
cles with automatic transmission, you need to have selected manual shift drive program M
(Y page 177). 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 196)
i The speed indicated in the speedometer
may differ slightly from the limit speed
stored.
Important safety notes If you fail to adapt your driving style, SPEED-
TRONIC can neither reduce the risk of an
accident nor override the laws of physics.
SPEEDTRONIC cannot take into account
road, weather or traffic conditions. SPEED-
TRONIC is only an aid. You are responsible for
the distance to the vehicle in front, for vehicle speed, for braking in good time, and for stay-
ing in lane.
If there is a change of drivers, advise the new driver of the speed stored. 194
