General notes You can shift gears yourself using the steering
wheel gearshift paddles. The transmission must
be in position hto do this.
Depending on which steering wheel gearshift
paddle is pulled, the automatic transmission
immediately shifts into the next gear up or
down, if permitted.
Mercedes-AMG vehicles: to use manual gear-
shifting, you have two options:
R temporary setting
R permanent setting
If you activate manual gearshifting, the multi-
function display will show the current gear
instead of transmission position h.
If manual gearshifting is deactivated, the gears
will be selected automatically. Temporary setting X
To activate: shift the DIRECT SELECT lever to
position h.
X Pull steering wheel gearshift paddle :or;.
The temporary setting will remain active for a
certain amount of time. Under certain condi-
tions, the minimum amount of time is extended, e.g. in the case of lateral acceleration, during an overrun phase or when driving on steep terrain.
X To deactivate: pull steering wheel gearshift
paddle ;and hold it in place.
or X Use the DIRECT SELECT lever to shift the
transmission position.
or X All vehicles (except Mercedes-AMG vehicles):
use the DYNAMIC SELECT button to change
the drive program.

For maximum acceleration, depress the
accelerator pedal beyond the pressure point.
The automatic transmission shifts to a lower
gear depending on the engine speed.
X Shift back up once the desired speed is
reached.
During kickdown, you cannot shift gears using
the steering wheel gearshift paddles. If you apply full throttle, the automatic trans-
mission shifts up to the next gear when the
maximum engine speed is reached. This pre-
vents the engine from overrevving.

General notes
Important safety notes G
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.
Drive sensibly – save fuel Observe the following tips to save fuel:
R The tyres should always be inflated to the rec-
ommended tyre pressure.
R Remove unnecessary loads.
R Remove roof racks when they are not needed.
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 Ser-
vice Booklet or by the service interval display.
Fuel consumption also increases when driving in cold weather, in stop-start traffic, on short jour-
neys 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 condi-
tions. Consumption can be significantly influ-
enced by your driving style. :

169Driving and parking Z

Cruise control or Distance Pilot DISTRONIC is
selected.
Vehicles with manual transmission: the lim-
iter 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 limiter If you wish to restrict the maximum speed of the
vehicle for an extended period (e.g. when driving with winter tyres), the desired maximum speed
can be set with the permanent limiter.
You can use the on-board computer to limit the
speed to a value between 160 km/h and
240 km/h (Y page 229).
Shortly before the stored speed is reached, it
appears in the multifunction display. When you
confirm the message with aor%, the
display is suppressed until you next switch off
the engine. The speed will only be displayed
again once the engine has been restarted.
The permanent limiter remains active even if the variable limiter is deactivated. The driven speed
will remain below the stored speed even in the
event of kickdown. Distance Pilot DISTRONIC
General notes Distance Pilot DISTRONIC regulates the speed
and automatically helps you maintain the dis-
tance to the vehicle detected in front. The sys-
tem detects vehicles using the radar sensor sys-
tem. Distance Pilot DISTRONIC brakes automat- ically to avoid exceeding the set speed or to
maintain the designated distance from the vehi- cle in front.
If Distance Pilot DISTRONIC detects that there is
a risk of a collision with the vehicle in front, you will be warned visually and acoustically. Without
your intervention, Distance Pilot DISTRONIC
cannot prevent a collision. An intermittent warn- ing tone will then sound and the distance warn- ing lamp will light up in the instrument cluster.
Brake immediately to increase the distance to
the vehicle in front, or take evasive action, pro-
vided it is safe to do so.
Distance Pilot DISTRONIC operates in the rangebetween 0 km/h and 200 km/h. Shift to 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 sys-
tem and prevents the brakes from overheating
and wearing too quickly.
Do not use Distance Pilot DISTRONIC on roads
with steep gradients.
For Distance Pilot DISTRONIC to assist you
when driving, the radar sensor system must be
operational.
Important safety notes G
WARNING
Distance Pilot DISTRONIC does not recognise
R people or animals
R stationary objects on the road, e.g. stopped
or parked vehicles
R oncoming vehicles or crossing traffic
As a result, Distance Pilot DISTRONIC 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. G
WARNING
Distance Pilot DISTRONIC cannot always
clearly identify other road users and complex
traffic situations.
In such cases, Distance Pilot DISTRONIC may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
R accelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, especially if Distance Pilot DISTRONIC
warns you. G
WARNING
Distance Pilot DISTRONIC brakes your vehicle with up to 50% of the maximum possible
deceleration. If this deceleration is not suffi-
cient, Distance Pilot DISTRONIC alerts you 180
Driving systemsDriving and parking

If there is no vehicle in front, Distance Pilot
DISTRONIC operates in the same way as cruise control.
If Distance Pilot DISTRONIC detects a slower-
moving vehicle in front, it brakes your vehicle. In
this way, the distance you have selected is main- tained.
If Distance Pilot DISTRONIC detects a faster-
moving vehicle in front, it increases the driving
speed. However, the vehicle is only accelerated
up to the speed you have stored.
i Distance Pilot DISTRONIC is deactivated
when you depress the brake, except when the vehicle is stationary.
Selecting the drive program Distance Pilot DISTRONIC supports a sporty
driving style when you select the S+drive pro-
gram (Y page 159) or manual gearshifting
(Y page 161). 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 want to change to the overtaking lane on
multi-lane roads, Distance Pilot DISTRONIC sup-
ports you if:
R you are driving faster than 70 km/h
R Distance Pilot DISTRONIC is maintaining the
distance to a vehicle in front
R you switch on the respective turn signal
R Distance Pilot DISTRONIC does not currently
detect a danger of collision
If these conditions are met, your vehicle accel-
erates. Acceleration will be interrupted if chang-
ing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
Stopping If Distance Pilot DISTRONIC detects that the
vehicle in front is stopping, it brakes your vehicle
until it is stationary.
Once your vehicle is stationary, it remains sta-
tionary 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 Distance Pilot DISTRONIC is activated,
the transmission is shifted automatically to
position jif:
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 is applied automati-
cally if Distance Pilot DISTRONIC is active when
the vehicle is stationary and:
R a system fault occurs
R the power supply is insufficient
If a fault occurs, the transmission may also shift
to position jautomatically.
Setting a speed Bear in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the 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 or press the cruise
control lever repeatedly until the desired
speed is reached.
X Release the cruise control lever.
The new speed is stored. Distance Pilot
DISTRONIC is activated and adjusts the vehi-
cle'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 Ato the pressure point.
The last stored speed increases or decreases

Tips for driving with Distance Pilot
DISTRONIC General notes
Pay particular attention in the following traffic
situations:
R Cornering, entering and exiting a bend: the
ability of Distance Pilot DISTRONIC to detect
vehicles when cornering is limited. Your vehi-
cle may brake unexpectedly or late.
R Driving on a different line: Distance Pilot
DISTRONIC may not detect vehicles driving in
a different lane. The distance to the vehicle in front will be too short.
R Other vehicles changing lane: Distance Pilot
DISTRONIC has not detected the vehicle cut-
ting in yet. The distance to this vehicle will be
too short.
R Narrow vehicles: Distance Pilot DISTRONIC
does not detect the vehicle in front on the
edge of the carriageway because of its narrow
width. The distance to the vehicle in front will
be too short.
R Obstacles and stationary vehicles: Distance
Pilot DISTRONIC does not brake for obstacles
or stationary vehicles. If, for example, the
detected vehicle turns a corner and an obsta-
cle or stationary vehicle is revealed, Distance Pilot DISTRONIC will not brake for them.
R Distance Pilot DISTRONIC may mistakenly
detect vehicles that are crossing your lane. If
you activate Distance Pilot DISTRONIC under the following conditions, the vehicle could
pull away unintentionally:
- at traffic lights with crossing traffic, for
example
- if there is a vehicle in front after a crossing
with the HOLD function activated
In such situations, brake if necessary. Distance Pilot DISTRONIC is then switched off. HOLD function
General notes The HOLD function can assist the driver in the
following situations:
R when pulling away, especially on steep slopes
R when manoeuvring on steep slopes
R when waiting in traffic The vehicle is kept stationary without the driver
having to depress the brake pedal.
The braking effect is cancelled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
Important safety notes G
WARNING
When leaving the vehicle, it can still roll away despite being braked by the HOLD function if:
R there is a malfunction in the system or in
the voltage supply
R the HOLD function is deactivated by the
accelerator pedal being depressed, e.g. by
a vehicle occupant
R the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with
R the battery is disconnected
There is a risk of an accident.
Before leaving the vehicle, always deactivate
the HOLD function and secure the vehicle
