Important safety notes
GWARNING
If flammable materials such as leaves, grass
or twigs are exposed to prolonged contact to
parts of the exhaust system that heat up, they
could ignite. There is a risk of fire.
Park the vehicle so that no flammable mate-
rials come into contact with parts of the vehi-
cle which are hot. Take particular care not to
park on dry grassland or harvested grain
fields.
GWARNING
If you leave children unattended in the vehi-
cle, they could set the vehicle in motion by,
for example:
R releasing the parking brake
R shifting an automatic transmission out of
parking position P
R shifting a manual transmission into neutral
R starting the engine
They could also operate vehicle equipment.
There is a risk of an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unattended in the vehicle.
! Always secure the vehicle correctly
against rolling away. Otherwise, the vehicle
or its drivetrain could be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the electric parking brake must be applied.
R on vehicles with manual transmission,
engage first gear or reverse gear.
R on vehicles with automatic transmission,
the transmission must be in position P and
the transmission position display must
show P in the multifunction display.
R the key must be removed from the ignition
lock.
R on uphill or downhill gradients, the front
wheels must be turned towards the kerb.
Switching off the engine
Important safety notes
GWARNING
The automatic transmission switches to neu-
tral position N when you switch off the engine.
The vehicle may roll away. There is a risk of
an accident.
After switching off the engine, always switch
to parking position P. Prevent the parked vehi-

Driving tips
General notes
GWARNING
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
The ECO display provides feedback on how
economical your driving characteristics are.
The ECO display assists you in achieving the
most economical driving style for the selec-
ted settings and existing conditions. Con-
sumption can be significantly influenced by
your driving style.
Example: ECO display
The ECO display consists of three bars:
R Acceleration
R Constant
R Coasting
The percentage count is the mean value of the
three bar values. The three bars and the mean
value begin at the value of 50%. A higher per-
centage count indicates a more economical
driving style.
The ECO display does not indicate the actual
fuel consumption and a fixed percentage
count in the ECO display does not indicate a
fixed consumption figure.
In addition to driving style, the consumption
is affected by many 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.
The evaluation of your driving style takes the
following three categories into consideration:
R Acceleration (evaluation of all accelera-
tion processes)
- The bar fills up: moderate acceleration,
especially at higher speeds
- The bar empties: sporty acceleration
R Constant (assessment of driving behav-
iour at all times)
- The bar fills up: constant speed and
avoidance of unnecessary acceleration
and deceleration
- The bar empties: fluctuations in speed
R Coasting (assessment of all deceleration
processes)
- The bar fills up: anticipatory driving,
keeping your distance and early release
of the accelerator. The vehicle can coast
without use of the brakes.
- The bar empties: frequent braking
i An economical driving style involves driv-
ing with 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 E (vehi-
cles with automatic transmission).
i On long journeys at a constant speed, e.g.
on the motorway, only the bar for Con‐
stant will change.
i The ECO display summarises the driving
characteristics from the start of the journey
to its completion. Therefore, there areDriving tips165Driving and parkingZ

dynamic changes in the bars at the start of
a journey. During a prolonged driving time,
these changes are smaller. For more
dynamic changes, perform a manual reset.
For further information on the ECO display,
see ( Y page 212).
Braking
Important safety notes
GWARNING
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 have selec-
ted manual drive program M(Y page 156).
i This also applies if you have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to prevent the
vehicle from gaining speed. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
i Briefly depressing the accelerator pedal
on downhill gradients while the manual
drive program M is temporarily activated
(vehicles with automatic transmission): the
automatic transmission may switch back to
the last active automatic drive program E
or S. The automatic transmission may shift
to a higher gear. This can reduce the
engine's braking effect.
Heavy and light loadsGWARNING
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.
Never use the brake pedal as a footrest. Do
not simultaneously depress both the brake
pedal and the accelerator pedal while driving.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If heavy demands are made on the brakes, do
not park the vehicle immediately. Drive on for
a short while. This allows the airflow to cool
the brakes more quickly.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed, paying attention to traffic con-
ditions. This improves the grip of the brakes.
Wet road surfaces
If you have driven for a long time in heavy rain
without braking, there may be a delayed reac-
tion from the brakes when braking for the first
time. This may also occur after a car wash or
after driving through deep water.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehi-
cle washed, brake firmly while paying atten-
tion to the traffic conditions. This will warm
up the brake discs, thereby drying them more
quickly and protecting them against corro-
sion.

Cruise control lever
You can operate cruise control and variable
SPEEDTRONIC with the cruise control lever.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:
R LIM indicator lamp off: cruise control is
selected.
R LIM indicator lamp on: variable SPEED-
TRONIC is selected.

iable SPEEDTRONICBTo deactivate cruise control
When you activate cruise control, the stored
speed is shown in the multifunction display
for five seconds.
In the multifunction display, the segments
between the stored speed and the maximum
speed light up.
Activation conditions
To activate cruise control, all of the following
activation conditions must be fulfilled:
R the electric parking brake must be
released.
R you are driving faster than 30 km/h.
R
ESP ®
must be switched on, but not inter-
vening.
R on vehicles with automatic transmission,
the selector lever must be in position D.
R on vehicles with manual transmission, a
gear must be engaged.
R cruise control must be selected.XTo select cruise control: check whether

Storing and maintaining the current
speed
You can store the current speed if you are
driving faster than 30 km/h.
XAccelerate the vehicle to the desired
speed.XBriefly press the cruise control lever
up : or down ?.XRemove your foot from the accelerator
pedal.
Cruise control is activated. The vehicle
automatically maintains the speed.
i Cruise control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by
automatically braking the vehicle.
i Vehicles with manual transmission:
R always drive at adequate, but not exces-
sive, engine speeds.
R change gear in good time.
R if possible, do not change down several
gears at a time.
Driving systems169Driving and parkingZ

Storing the current speed and calling up
the last stored speedGWARNING
If you call up a stored speed and this is dif-
ferent from the current speed, the vehicle
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again.
XBriefly pull the cruise control lever towards
you =.XRemove your foot from the accelerator
pedal.
The first time cruise control is activated, it
stores the current speed or regulates the
speed of the vehicle to the previously
stored speed.
Setting a speed
Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the set speed.
XPress the cruise control lever up : for a
higher speed or down ? for a lower speed.XKeep the cruise control lever pressed until
the desired speed is reached.XRelease the cruise control lever.
The new speed is stored.XTo 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.XTo adjust the set speed in 10 km/h
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 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:
XBriefly press the cruise control lever for-
wards B.
or
XBrake
or
XBriefly press the cruise control lever in the
direction of arrow A.

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 into position N while driving
If cruise control is deactivated, you will hear
a warning tone. You will see the Cruise
control off message in the multifunction
display for approximately five seconds.
i The last speed stored is cleared when you
switch off the engine.

Storing the current speed
You can use the cruise control lever to limit
the speed to any speed above 30 km/h while
the engine is running.XBriefly press the cruise control lever
up : or down ?.
The current speed is stored. For five sec-
onds, the multifunction display shows the
stored speed, e.g. Limit 100 km/h.
The segments in the speedometer light up
from the start of the scale up to the stored
speed.
Storing the current speed and calling up
the last stored speed
GWARNING
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.
XBriefly pull the cruise control lever towards
you =.XTo adjust the set speed in 1 km/h incre-
ments: briefly press the cruise control
lever up : to the pressure point for a
higher speed, or down ? for a lower speed.
or
XKeep the cruise control lever pressed to the
pressure point until the desired speed is
set. Press the cruise control lever up : for
a higher speed or down ? for a lower
speed.XTo adjust the set speed in 10 km/h
increments: briefly press the cruise con-
trol lever up : past the pressure point fora higher speed, or down ? for a lower
speed.
or
XKeep the cruise control lever pressed
beyond the pressure point until the desired
speed is set. Press the cruise control lever
up : for a higher speed or down ? for a
lower speed.
Deactivating variable SPEEDTRONIC
It is not possible to deactivate variable
SPEEDTRONIC by braking.
There are several ways to deactivate variable
SPEEDTRONIC:
XBriefly press the cruise control lever for-
wards B.
or
XBriefly press the cruise control lever in the
direction of arrow A.
LIM indicator lamp ; in the cruise control
lever goes out. Variable SPEEDTRONIC is
deactivated.
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.
Kickdown
Switching SPEEDTRONIC to passive
If you depress the accelerator pedal beyond
the pressure point (kickdown), SPEED-
TRONIC is switched to passive. The following
message appears in the multifunction dis-
play: SPEEDTRONIC passive .
You can then exceed the stored speed.
SPEEDTRONIC is activated again if you:
172Driving systemsDriving and parking

Rdrive slower than the stored speed without
kickdown
R set a new speed or
R call up the last speed stored again
The SPEEDTRONIC passive message in the
multifunction display disappears.
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 223).
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 so that the set speed is not
exceeded.
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, DIS-
TRONIC 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.
Important safety notesGWARNING
DISTRONIC PLUS does not react to:
R people or animals
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic
As a result, DISTRONIC PLUS may neither give
warnings nor intervene in such situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
GWARNING
DISTRONIC PLUS cannot always clearly iden-
tify other road users and complex traffic sit-
uations.
In such cases, DISTRONIC PLUS may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
R accelerate unexpectedly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, in particular when warned to do so by
DISTRONIC PLUS.
GWARNING
DISTRONIC PLUS brakes your vehicle with up
to 50% of the maximum possible deceleration.
If this deceleration is not sufficient, DIS-
TRONIC PLUS alerts you with a visual and
acoustic warning. There is a risk of an acci-
dent.
Driving systems173Driving and parkingZ

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 keeps to the vehicle in
front, dependent on vehicle speed. You can
see this distance in the multifunction display
( Y page 179).
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.
XTo increase: turn control = in direc-
tion ;.
DISTRONIC PLUS then maintains a greater
distance between your vehicle and the
vehicle in front.XTo decrease: turn control = in direc-
tion :.
DISTRONIC PLUS then maintains a shorter
distance between your vehicle and the
vehicle in front.Deactivating DISTRONIC PLUS
There are several ways to deactivate DIS-
TRONIC PLUS:
XBriefly press the cruise control lever for-
wards :.
