controlled manner. The spinning of the
wheels results in a cutting action, which
provides better grip.
R ESP ®
still provides support when you
brake.
Characteristics when ESP ®
is deactivated
If
ESP ®
is deactivated and one or more wheels
start to spin, the 00E5 ESP®
warning lamp in
the instrument cluster does not flash. In such
situations, ESP ®
will not stabilize the vehicle.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R the engine's torque is no longer limited and
the drive wheels are able to spin without
restriction. The spinning of the wheels
results in a cutting action, which provides
better grip.
R traction control is still activated.

trailer stabilization G
WARNING
If road and weather conditions are poor,
trailer stabilization will not be

able to prevent
the vehicle/trailer combination from
swerving. Trailers with a high center of gravity
can tip over before ESP ®
can detect this.
There is a risk of an accident.
Always adapt your driving style to the
prevailing road and weather conditions.
If your vehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
In this situation, ESP ®
assists you and can
detect if the vehicle/trailer combination
begins to lurch. ESP ®
slows the vehicle down
by braking and limiting the engine output until the vehicle/trailer combination has
stabilized.
Trailer
stabilization is active above

speeds of
about 40 mph (65 km/h).
Trailer stabilization does not work if ESP ®
is
deactivated because of a malfunction. EBD (electronic brake force
distribution)
i Observe the "Important safety notes"
section ( Y page 64). G
WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This
increases the risk of skidding

and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified
specialist workshop.
Observe information regarding indicator and
warning lamps ( Y page 259) as well as
display messages ( Y page 233).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking. PRE-SAFE
®
Brake
i Observe the "Important safety notes"
section ( Y page 64).
PRE-SAFE ®
Brake is only available

in vehicles
with DISTRONIC PLUS.
If PRE-SAFE ®
Brake is to aid you, the radar
sensor system must be:
R activated (Y page 229)
R operational
With the help of the radar sensor system,
PRE-SAFE ®
Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
PRE-SAFE ®
Brake can help you to minimize
the risk of a collision with a vehicle ahead or Driving safety systems

Neutral
Do not shift the transmission to
N
while driving. The transmission
could otherwise be damaged.
No power is transmitted from the
engine to the drive wheels.
Releasing the brakes will allow
you
to move the vehicle freely, e.g. to
push it or tow it.
If ESP ®
is deactivated or faulty:
only shift the transmission to
position N if the vehicle is in danger
of skidding, e.g. on icy roads.
! Rolling in neutral N can damage
the drive train. 003A
Drive
The automatic transmission
changes gear automatically. All
forward gears are available.
Changing gear
The automatic transmission shifts to the
individual gears automatically when it is in
transmission position D. This automatic
gearshifting behavior is determined by:
R a shift range restriction, if selected
R the selected drive program:
E/S (Y page 151)
R the position of the accelerator pedal
R the road speed Driving tips
Kickdown Use kickdown for maximum acceleration.
X
Depress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to a
lower gear depending on the

engine speed.
X Ease off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back

up.
Towing a trailer X
When traveling downhill, switch to a lower
gear if the automatic transmission
constantly switches between two gears.
X Engaging a lower gear and reducing the
speed reduces the risk of the engine
overheating. Program selector button

lose control of the vehicle. If the gradient is
too steep for your
vehicle,
drive back down in
reverse gear.
Maximum gradient-climbing capability i
If the load on the front axle is reduced
when pulling away on a steep uphill slope,
the front wheels have a tendency to spin.
4ETS recognizes this and brakes the
wheels accordingly. The rear wheel torque
is increased, making it easier to drive off.
Hilltops When driving up an uphill gradient, slightly
reduce pressure on the accelerator
immediately before reaching the brow of the
hill.
Make
use of
the

vehicle's own impetus to
travel over the brow.
This style of driving prevents:
R the vehicle from lifting off the ground on the
brow of a hill
R the vehicle from traveling too quickly down
the other side
Driving downhill R
Drive slowly.
R Do not drive at an angle down steep
inclines. Steer into the line

of fall and drive
with the front wheels aligned straight.
Otherwise, the vehicle could slip sideways,
tip and rollover.
R Before tackling steep downhill gradients,
select shift range 1.
R Activate DSR. If this is not sufficient, brake
gently. When doing so, make sure that the
vehicle is facing in the direction of the line
of fall.
R Check that the brakes are working normally
after a long downhill stretch. Driving systems
Cruise Control
Important safety notes Cruise control maintains a constant road
speed for you. It
brakes

automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
select shift range 1, 2 or 3 in good time. 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
conditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 20 mph
(30 km/h).
If you fail to adapt your driving style, cruise
control can neither reduce the risk of an
accident nor override the laws of physics.
Cruise control cannot take into account the
road, traffic and weather conditions. Cruise
control 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
staying in your 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 slippery road surfaces. Braking or
accelerating could 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.
i Cruise control should not be activated
when driving off-road. Driving systems

Activating the HOLD function
X
Make sure that the activation conditions
are met.
X Depress the brake pedal.
X Quickly depress the brake pedal further
until 00D9 appears in the multifunction
display.
The HOLD function is activated. You can
release the brake pedal.
i If depressing the brake pedal the first
time does not activate the HOLD function,
wait briefly and then try again.
Deactivating the HOLD function The HOLD function is deactivated
automatically if:
R
you accelerate and the transmission is in
position D or R
R the transmission is in position P.
R you depress the brake pedal again with a
certain amount of pressure until 00D9
disappears from the multifunction display
R you activate DISTRONIC PLUS
When the HOLD function is activated, the
automatic transmission is shifted
automatically to position P if:
R the driver's door is open and the driver's
seat belt is unfastened.
R the engine is switched off, unless it is
automatically switched off by the ECO
start/stop function.
R the hood is opened.
R a system malfunction occurs.
R the power supply is not sufficient.
The horn will also sound
at regular intervals if
the HOLD function is activated and you:
R switch the engine off, open the driver's
door and remove your seat belt
R open the hood
The sounding of the horn alerts you to the fact
that the vehicle has been parked while the
HOLD function is still activated. If you attempt to lock the vehicle, the tone becomes louder.
The vehicle is not locked until the HOLD
function is deactivated.
i
If the engine has been switched off, it
cannot be started again until the HOLD
function has been deactivated.
If there is a malfunction in the system or
power supply while the HOLD function is
activated, the Brake Immediately message
is shown in the multifunction display.
Immediately depress the brake firmly until
the warning message in the multifunction
display goes out.
You can

also shift the transmission to position
P. This deactivates the HOLD function. PARKTRONIC
Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a
replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting a parking space. When
maneuvering, parking or pulling out of a
parking space, make sure that there are no
persons, animals or objects in the area in
which you are maneuvering.
!
When parking, pay particular attention

to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a 180
