Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos-
sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.

ist workshops: ( Y page 24).
Running-in notes
Important safety notes
New or replaced brake pads/linings and
discs only reach their optimum braking effect
after several hundred kilometres of driving.
Compensate for the reduced braking effect
by applying greater force to the brake pedal.
The first 1,500 km
If you treat the engine with sufficient care
from the very start, you will be rewarded with
excellent performance for the remainder of
the engine's life.
R Drive at varying vehicle speeds and engine
speeds for the first 1,500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R Change gear in good time, before the rev
counter needle is Ô of the way to the red
area of the rev counter.
R Do not shift down a gear manually in order
to brake.
Vehicles with automatic transmission:
R Try to avoid depressing the accelerator
pedal beyond the point of resistance (kick-
down).
After 1,500 km, you may gradually bring the
vehicle up to full road and engine speeds.
i You should also observe these notes on
running-in if the engine or parts of the drive
train on your vehicle have been replaced.
Driving
Important safety notes
GWARNING
Objects in the driver's footwell can restrict the
pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle
is jeopardised. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Fit the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use
loose floormats.
GWARNING
Unsuitable footwear can hinder correct usage
of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals.
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.
144DrivingDriving and parking

GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only set the automatic transmission to the
respective drive positions when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. Otherwise, you could damage the
drive train.

i If the key does not belong to the vehicle,
it can still be turned in the ignition lock.
However, the ignition will not be switched
on. The engine cannot be started.
Starting the engine
Important safety notesGWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
GWARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
! Do not depress the accelerator pedal
when starting the engine.
i Vehicles with a petrol engine: the
engine runs at a higher engine speed during
the cold start procedure so that the cata-
lytic converter can reach operating tem-
perature more quickly. The sound of the
engine may change as a result.

is a risk of an accident.
When engaging transmission position D or R,
always firmly depress the brake pedal and do
not simultaneously accelerate.
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-
cle from rolling away by applying the parking
brake.
i Bear in mind that the power transmission
between the engine and the transmission
is interrupted when the engine is switched
off.
To prevent the vehicle from rolling away:

In drive program M, you can change gear
yourself using the steering wheel gearshift
paddles.
If you pull the left or right steering wheel gear-
shift paddle when in automatic drive program
E or S, the automatic transmission shifts into
drive program M for a limited time. Depend-
ing on which gearshift paddle is pulled, the
automatic transmission immediately shifts
into the next gear down or up.
i You can only change gear with the steer-
ing wheel gearshift paddles when the trans-
mission is in position D.

drive program, see ( Y page 156).
Automatic drive program
Drive program E is characterised by the fol-
lowing:
R comfort-oriented engine settings
R optimal fuel consumption resulting from
the automatic transmission shifting up
sooner
R the vehicle pulling away more gently in
forward and reverse gears, unless the
accelerator pedal is depressed fully
R increased sensitivity. This improves driving
stability on slippery road surfaces, for
example
R the automatic transmission shifting up
sooner. This results in the vehicle being
driven at lower engine speeds and the
wheels being less likely to spin
Drive program S is characterised by the fol-
lowing:
R sporty engine settings
R the automatic transmission shifting up
later
R as a result of the later automatic transmis-
sion shift points, the fuel consumption pos-
sibly being higher
Manual drive program
Introduction
In manual drive program M, you can change
gear yourself by using the steering wheel
gearshift paddles. For this, the transmission
must be in position D. The gear currently
selected and engaged is shown in the multi-
function display.
Manual drive program M differs from drive
programs E and S with regard spontaneity,
responsiveness and smoothness of gear
changes.

Activating the manual drive program
Activating permanently
XPress the program selector button
( Y page 155) repeatedly until M appears in
the multifunction display.
Manual drive program M remains active
until drive program E or S is engaged.
Activating temporarily
XPull the right or left steering wheel gearshift
paddle ( Y page 156).
M is shown in the multifunction display.
Manual drive program M is temporarily
active. Depending on which gearshift pad-
dle is pulled, the automatic transmission
immediately shifts into the next gear down
or up.
i When manual drive program M is activa-
ted via the steering wheel gearshift pad-
dles, the temporarily active manual drive
program M will be deactivated automati-
cally after a limited time, if the driving sit-
uation permits. In this case, the automatic
transmission shifts into the automatic drive
program that was last engaged, i.e. E or S.
When driving on downhill gradients, the
temporarily active manual drive program
M will only be deactivated if the accelerator
pedal is depressed while the vehicle is roll-
ing downhill.
Upshifting
XPull the right-hand steering wheel gearshift
paddle ( Y page 156).
The automatic transmission shifts up to the
next gear.
i In order to prevent engine damage, the
automatic transmission automatically
shifts up if:
R the maximum engine speed for the cur-
rently engaged gear is reached and
R you continue to accelerate.
DownshiftingXPull the left-hand steering wheel gearshift
paddle ( Y page 156).
The automatic transmission shifts down to
the next gear.
i If you slow down or stop without shifting
down, the automatic transmission auto-
matically shifts down.
i For maximum acceleration, pull the left-
hand steering wheel gearshift paddle until
the transmission selects the optimum gear
for the current speed.
i If the engine exceeds the maximum
engine speed when shifting down, the auto-
matic transmission protects against engine
damage by not shifting down.
Kickdown
You can also use kickdown for maximum
acceleration in manual drive program M.
XDepress the accelerator pedal beyond the
pressure point.
The transmission shifts to a lower gear
depending on the engine speed.XShift back up once the desired speed is
reached.
i During kickdown, you cannot shift gears
using the steering wheel gearshift paddles.
i If you apply full throttle, the automatic
transmission shifts up to the next gear
when the maximum engine speed is
reached. This prevents the engine from
overrevving.
Switching off the manual drive program
XPress the program selector button
( Y page 155) repeatedly until E or S
appears in the multifunction display.Automatic transmission157Driving and parkingZ

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

Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Winter operation"
section ( Y page 318).
Driving with summer tyres
Observe the notes in the "Winter operation"
section ( Y page 318).
Slippery road surfaces
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.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XVehicles with manual transmission:
shift to neutral.XVehicles with automatic transmission:
shift the transmission to position N.XTry to bring the vehicle under control by
using corrective steering.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges. You
should pay special attention to road condi-
tions when temperatures are around freezing
point.
i For more information on driving with
snow chains, see ( Y page 319).
Driving systems
Cruise control
General notes
Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding 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 drive program
M (Y page 156). 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.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 30 km/h.
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 the
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.

General notes
Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention can assist you during
manoeuvring and parking. You may also use
PARKTRONIC ( Y page 182).
Important safety notes
Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that no persons, animals or
objects are in the manoeuvring range.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable.
GWARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park-
ing Assist parking procedure.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at
a sharp angle. Otherwise, you may damage
the wheels or tyres.
Active Parking Assist may also display spaces
not suitable for parking, e.g.:
R parking or stopping prohibitions
R in front of driveways or entrances and exits
R unsuitable surfaces
186Driving systemsDriving and parking

Active Parking Assist is switched on automat-
ically when driving forwards. The system is
operational at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking
spaces on both sides of the vehicle.
Active Parking Assist will only detect parking
spaces:
R that are parallel or at right angles to the
direction of travel
R that are parallel to the direction of travel
and are at least 1.5 m wide
R that are parallel to the direction of travel
and at least 1.0 m longer than your vehicle
R that are at right angles to the direction of
travel and at least 1.0 m wider than your
vehicle
i In the case of parking spaces that are at
right angles to the direction of travel,
please ensure that the parking space is
long enough to accommodate your vehicle.
When driving at speeds below 30 km/h, you
will see parking symbol ; as a status indi-
cator in the instrument cluster. When a park-
ing space has been detected, an arrow
towards the right or the left also appears.
Active Parking Assist only displays parking
spaces on the front-passenger side as stand-
ard. Parking spaces on the driver's side are
displayed as soon as the turn signal on the
driver's side is activated. When parking on the
driver's side, this must remain switched on
until you acknowledge the use of Active Park-
ing Assist by pressing the a button on the
multifunction steering wheel.
The system automatically determines
whether the parking space is parallel or at
right angles to the direction of travel.
A parking space is displayed while you are
driving past it, and until you are approx-
imately 15 m away from it.ParkingGWARNING
Active Parking Assist merely aids you by inter-
vening actively in the steering. There is a risk
of accident if you do not apply the brakes
yourself.
Always apply the brakes yourself when park-
ing and manoeuvring.
XStop the vehicle when the parking symbol
shows the desired parking space in the
instrument cluster.XVehicles with manual transmission: shift to
