Driving tips Accelerator pedal position
Your style of driving influences how AUTO-
TRONIC shifts gear:
R little throttle: early upshifts

Kickdown
Use kickdown for maximum acceleration.

The transmission shifts to a lower gear
depending on the engine speed.
X Ease off the accelerator pedal once the
desired speed is reached.
The transmission shifts back up. Trailer towing

Overview of driving systems
The vehicle's driving systems are described
on the following pages:
R Cruise control* and Speedtronic*, which
are used to control the speed of the vehicle
R Parktronic* and active parking assist*,
which can help you to find a parking space,
to manoeuvre and park
R ECO Start-Stop function*, helps you to
save fuel
The ABS, BAS, adaptive brake lights, ESP ®
and STEER CONTROL driving safety systems
are described in the "Driving safety systems"
section ( Ypage 55). Cruise control*
Cruise control maintains a constant road
speed for you. You must select a low gear in
good time on long and steep downhill gradi-
ents, especially if the vehicle is laden or tow-
ing a trailer. By doing so you will make use of
the braking effect of the engine, which
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly. G
Risk of accident
Never depress the brake pedal continu-
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying
constant slight pedal pressure. This causes
the brake system to overheat, increases
the braking distance and can lead to the
brakes failing completely. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid.
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. G
Risk of accident
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in good
time. G
Risk of accident
Do not use cruise control:
R in road and traffic conditions which do
not allow you to maintain a constant
speed (e.g. heavy traffic or winding
roads). You could otherwise cause an
accident.
R on slippery roads. Braking or accelerat-
ing 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
Cruise control lever You can operate cruise control and variable
Speedtronic with the cruise control lever.Controls

Setting a speed X
Press the cruise control lever up 1for a
higher speed or down 4for a lower speed.
X Keep the cruise control lever pressed until
the desired speed is reached.
X Release the cruise control lever.
The new speed is stored.
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.
i Vehicles with AUTOTRONIC*:
When you decelerate the vehicle using the
cruise control lever, AUTOTRONIC changes
down if deceleration is insufficient.
Making fine adjustments in
1 km/hincrements X
Briefly press the cruise control lever up
1 for a higher speed or down 4for a
lower speed.
The last speed stored is increased or
reduced. Deactivating cruise control There are several ways to deactivate cruise
control:
X
Briefly press the cruise control lever for-
wards 6.
or
X Brake.
or
X Briefly press the cruise control lever in the
direction of arrow 5.
Variable Speedtronic is selected. LIM indi-
cator lamp 2in the cruise control lever
lights up.
Cruise control is automatically deactivated if,
for example:
R aquaplaning is detected
R you press the clutch pedal for more than
four seconds on vehicles with a manual
transmission
R you move the selector lever to Nwhile driv-
ing in vehicles with AUTOTRONIC*
i The last speed stored is cleared when you
switch off the engine. Speedtronic*
Speedtronic is used to make sure that you do
not exceed a stored speed. You must select
a low gear in good time on long and steep
downhill gradients, especially if the vehicle is
laden or towing a trailer. By doing so you will
make use of the braking effect of the engine,
which relieves the load on the brake system
and prevents the brakes from overheating
and wearing too quickly. G
Risk of accident
Never depress the brake pedal continu-
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying
constant slight pedal pressure. This causes
the brake system to overheat, increases
the braking distance and can lead to the
brakes failing completely. G

Example: sensors in the front bumper,
left-hand side
Range of the sensors The sensors must be free of dirt, ice and
slush, otherwise they may not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them
(Y page 196). Side view Top view
Front sensors
Centre Approximately 100 cm
Corners Approximately 80 cm
Rear sensors
Centre Approximately 120 cm
Corners Approximately 80 cm
!
When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer towbars. Parktronic
does not detect such objects when they are
in the immediate vicinity of the vehicle. You
could damage the vehicle or the objects. Ultrasonic sources such as an automatic
car wash, a lorry's compressed-air brake
system or a pneumatic drill could cause
Parktronic to malfunction.
Minimum distance Centre Approximately 20 cm
Corners Approximately 20 cm
If there is an obstacle within this range, all
warning displays light up and a tone sounds.
If the distance falls below the minimum clear-
ance, it may no longer be shown.
Warning displays
The warning displays show the distance
between the sensors and the obstacle. The
warning display for the front area is located
on the dashboard above the centre air vents.
The warning display for the rear area is loca-
ted on the roof lining in the rear compart-
ment.Controls

Parktronic is automatically activated
when you turn the key to position 2in the
ignition lock.
Trailer towing* Parktronic is deactivated for the rear area
when you establish an electrical connection
between your vehicle and a trailer.
! Remove the detachable trailer coupling if
it is no longer required. Parktronic meas-
ures the minimum detection range to an
obstacle from the bumper, not the ball cou-
pling. Active parking assist*
Active parking assist is an electronic parking
aid with ultrasound. Ultrasound is used to
measure the road on both sides of the vehicle.
A suitable parking space is indicated by the
parking symbol. Active steering intervention
can assist you during parking. You may also
use Parktronic (Y page 119). When Parktronic
is deactivated, active parking assist is also
unavailable. G
Risk of accident
Active parking assist is merely an aid and
may sometimes recommend parking
spaces that are not suitable for parking.
These might be, for example, spaces where
parking is prohibited, driveways, unsuitable
surfaces, etc.
Active parking assist measures the parking
space as you drive past it. Any later
changes to the parking space are not taken
into account. This may be the case, for
instance, when the vehicle parked in front
of or behind the space changes its position
or when an obstacle is moved into the park-
ing space.
Active parking assist does not relieve you
of the responsibility of paying attention. If
you rely solely on Active parking assist, you
could cause an accident and injure yourself
and others.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
manoeuvring. G
Risk of accident
Objects located above the height range of
Active parking assist will not be detected when the parking space is measured. These
are not taken into account when the park-
ing procedure is calculated, e. g. overhang-
ing loads, tail sections or loading ramps of
goods vehicles. In some circumstances,
Active parking assist may therefore guide
you into the parking space too early. This
may lead to a collision. For this reason, you
should avoid using Active parking assist in
such situations.
G
Risk of accident
The front of the vehicle will veer out in the
direction of the oncoming traffic during the
parking operation. In some cases the vehi-
cle will also take you onto sections of the
oncoming lane during the parking proce-
dure.
You are responsible for safety at all times
and must pay attention to any road users
approaching or passing. Stop the vehicle if
necessary or cancel the Active parking
assist parking procedure. G
Risk of injury
Make sure that no persons or animals are
in the manoeuvring range. Otherwise, they
could be injured. Controls
