When shifting between 5thand 6thgear,
you should always push the gear lever all
the way to the right. Otherwise, you could
shift unintentionally into thirdorfourth
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.

especially when the vehicle is laden, you

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

A warning tone sounds. the multi-function
display shows the message: Park Assist
cancelled .
When active parking assist is cancelled, you
must steer again yourself.
Trailer towing* For vehicles with a trailer coupling, the mini-
mum length for parking spaces is slightly
increased.
If you have attached a trailer to your vehicle,
you should not use active parking assist.
Once the electrical connection is established
between your vehicle and the trailer, active
parking assist is no longer available. Park-
tronic is deactivated for the rear area. ECO start/stop function*
The ECO start/stop function automatically
switches off the engine as soon as you stop
the vehicle and restarts the engine as soon as
you prepare to pull away again. Each time the
engine is started using the key, the ECO
start/stop function is activated.
Conditions for the automatic engine
switch-off The ECO start/stop function automatically
switches off the engine if all of the following
conditions are met:
R
you have shifted to neutral
R the clutch pedal is not depressed
R the brake pedal is depressed
R the vehicle speed is very low
R the engine has reached its operating tem-
perature
R the indicator lamp in the ECO button is lit
green
R the bonnet is closed
R the outside temperature is within the com-
fort range R
the battery is sufficiently charged
R the brake vacuum is stable
Conditions for the automatic engine

switches on the engine if one of the following
conditions is met:
R

R the clutch pedal is depressed
R the vehicle speed exceeds a certain thresh-
old
R the ECO button is pressed
R the brake vacuum has decreased
R the battery charge has dropped
R the demister function of Thermotronic* is

Fitting the ball coupling
X Make a note of the ball coupling key num-
ber.
i You can use this number to obtain a
replacement key from a Mercedes-Benz
Service Centre. G
Risk of injury
If the ball coupling does not engage cor-
rectly when it is mounted, the vehicle/
trailer combination is not secured and the
trailer could come loose. This could cause
an accident. Fit the ball coupling carefully
and make sure that it engages in position
correctly.
Vehicles without ECO start/stop func-
tion: the attachable ball coupling is on the
right of the stowage compartment in the lug-
gage compartment (Y page 160).

right-hand side of the luggage compart-
ment.

and consequently the vehicle's gradient-
climbing capability, decrease with increas-
ing altitude.
If the trailer swings from side to side:
X Do not accelerate.
X Do not counter-steer.
X Brake if necessary. G
Risk of accident
On no account should you attempt to draw
the vehicle/trailer combination out by
increasing speed. Removing the ball coupling
X Pull the protective cap off the lock in the
handwheel.
X Insert the key into the lock in the hand-
wheel.
X Turn the key clockwise.
The lock is unlocked.
X Hold the ball coupling. Pull the handwheel
away from the ball coupling and turn it
clockwise until it engages.
The green area on the ball coupling is
aligned with the red mark on the hand-
wheel. X
Pull out the ball coupling downwards.
X Clean the ball coupling if it is dirty.
X Vehicles without ECO start/stop func-
tion*: open the stowage compartment on
the right of the luggage compartment.
X Fold the trim downwards.
X Vehicles with start/stop function*:
open the luggage compartment floor.
X Remove the protective cap from the ball
coupling recess.
X Press the protective cap into the ball cou-
pling recess until it engages.
Storing the ball coupling X
Store the ball coupling with the key inser-
ted in the ball coupling recess.
X Vehicle without ECO start/stop func-
tion: Secure the ball coupling in place using
the retainer strap. G
Risk of accident
Do not carry the ball coupling in the vehicle
interior if it is not secured.
Otherwise, you and others could be injured
by the ball coupling being thrown around if
you: R
brake sharply
R change direction suddenly
R are involved in an accident Trailer power supply
When it leaves the factory, your vehicle's
trailer socket outlet is equipped with a per-
manent power supply and a power supply that
is switched on via the ignition lock.
The permanent power supply is supplied via
trailer socket pin 9.
The power supply that is switched on via the
ignition lock is supplied via trailer socket pin
10.
! You can connect consumers with a power
rating of up to 240 W to the permanent
power supply and up to 180 W to the power
supply that is switched on via the ignition
lock.
You must not charge a trailer battery using
the power supply.
The trailer's turn signal lamps are only guar-
anteed to function when bulbs are used.
You can obtain further information about
installing the trailer electrics from a qualified Operation
