Transmission
93
6-speed manual transmission
Vehicles without ECO Start-Stop-Function* (6-
speed manual transmission)
!
When shifting between 5thand 6thgear,
you should always push the gear lever all
the way to the right. You could otherwise
shift unintentionally into 3rdor4th gear
and damage the transmission.
Do not exceed the maximum speed for the
individual gears.
If you shift down at too high a speed (trans-
mission braking), this can cause the engine
to overrev, leading to engine damage.
! On long and steep downhill gradients,
especially when the vehicle is laden, you
must shift to a lower gear in time. This will use the braking effect of the engine, so less
braking will be required to prevent the vehi-
cle from gaining speed. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
Engaging reverse gear
! Only engage reverse gear when the vehi-
cle is stationary, otherwise the transmis-
sion could be damaged.
X Pull the gear lever up, move it to the left and
then back.
Gearshift indicator (BlueEFFI-
CIENCY*vehicles) i
Observing the gearshift indicator in the
instrument cluster's multi-function display
will help you to improve the fuel economy
of your vehicle. 1
Upshift indicator
X Shift up or down a gear when the corre-
sponding indicator appears in the instru-
ment cluster's multi-function display.
The shift indicator is meant as a recommen-
dation for an economical driving style. How-
ever, always observe traffic conditions, as
your driving style is determined, in the first
instance, by the traffic situation. Controls

Driving sys
tems 115Driving systems
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
