system. Even small amounts of the wrong
fuel can result in damage to the fuel system
and the engine. Notify a qualified specialist workshop and have the fuel tank and fuel
lines drained completely.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not switch on the ignition if you accidentally refuel with the wrong
fuel. Otherwise, fuel can enter the fuel sys-tem. Even small amounts of the wrong fuel
could result in damage to the fuel system
and the engine. The repair costs are high.
Notify a qualified specialist workshop and
have the fuel tank and fuel lines drained
completely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Use a filter when adding fuel from a fuel
can. The fuel lines and/or the fuel injection system could otherwise be blocked by par-
ticles from the fuel can.
Do not get into the vehicle again during the
refuelling process. Otherwise, electrostatic
charge could build up again.
If you overfill the fuel tank, some fuel may
spray out when you remove the fuel pump
nozzle.

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

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

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 are appropriate for maintaining a
steady speed for a prolonged period. You can
store any road speed above 30 km/h.
The speed indicated in the speedometer may differ slightly from the speed stored.
Important safety notes If you fail to adapt your driving style, cruise
control can neither reduce the risk of an acci-
dent nor override the laws of physics. Cruise
control cannot take into account road,
weather or traffic conditions. Cruise control is only an aid. You are responsible for the dis-
tance to the vehicle in front, for vehicle speed,
for braking in good time, and for staying in
lane.
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintain a constant speed, e.g.
in heavy traffic or on winding roads
R on smooth or slippery roads. Braking or
accelerating can cause the drive wheels to lose traction and the vehicle could then
skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is a change of drivers, advise the new
driver of the speed stored. Cruise control lever :

X Briefly press the cruise control lever up :
or down ?.
The current speed is stored and shown in
the multifunction display.
Storing or calling up the speed G
WARNING
If you call up the stored speed and it is lower
than the current speed, the vehicle deceler-
ates. If you do not know the stored speed, the vehicle could decelerate unexpectedly. There
is a risk of an accident.
Pay attention to the road and traffic condi-
tions before calling up the stored speed. If you do not know the stored speed, store the
desired speed again.

multifunction display disappears.
Deactivating variable SPEEDTRONIC
It is not possible to deactivate variable
SPEEDTRONIC by braking.
There are several ways to deactivate variable SPEEDTRONIC:
X Briefly press the cruise control lever for-
wards B.
or
X Briefly press the cruise control lever in the
direction of arrow A.
LIM indicator lamp ;in the cruise control
lever goes out. Variable SPEEDTRONIC is

Cruise control or DISTRONIC PLUS is selec-
ted.
Vehicles with manual transmission:
SPEEDTRONIC switches off if you shift to a
higher gear and as a result, the engine speed
is too low.
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 a value between
160 km/h(e.g. for driving on winter tyres) and
the maximum speed (Y page 251).
Shortly before the stored speed 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
General notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the dis-
tance to the vehicle detected in front. Vehi-
cles are detected with the aid of the radar
sensor system. DISTRONIC PLUS brakes
automatically to avoid exceeding the set
speed or to maintain the designated distance from the vehicle in front.
Change into a lower gear in good time on long
and steep downhill gradients. Take particular note of this when driving a laden vehicle. 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 DISTRONIC PLUS detects that there is a risk of a collision, you will be warned visually and
acoustically. Without your intervention,
DISTRONIC PLUS cannot prevent a collision.
An intermittent warning tone will then sound
and the distance warning lamp will light up in
the instrument cluster. Brake immediately to
increase the distance to the vehicle driving in front, or take evasive action, provided it is
safe to do so.
DISTRONIC PLUS operates in the range
between 0 km/h and 200 km/h.
Do not use DISTRONIC PLUS while driving on
roads with steep gradients. 196

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 202).
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-
