uations, PRE-SAFE
®
PLUS takes pre-emptive
measures to protect the vehicle occupants.
Important safety notes The intervention of PRE-SAFE
®
PLUS cannot
prevent an imminent collision.
The driver is not warned before the intervention
of PRE-SAFE ®
PLUS.
PRE-SAFE ®
PLUS does not intervene:
R if the vehicle is reversing
R when the vehicle is towing a trailer and there
is a risk of a rear-end collision
When driving, or when parking or exiting a park-
ing space with assistance from Parking Pilot,
PRE-SAFE ®
PLUS will not apply the brakes.
Function PRE-SAFE
®
PLUS intervenes in certain situa-
tions if the radar sensor system detects an
imminent head-on or rear-end collision.
PRE-SAFE ®
PLUS takes the following measures
depending on the hazardous situation detected:
R if the radar sensor system detects that a
head-on collision is imminent, the seat belts
are pre-tensioned
R if the radar sensor system detects that a rear-
end collision is imminent:
- the rear hazard warning lamps are activa-
ted and flash at a higher frequency
- the brake pressure is increased if the driver
applies the brakes when the vehicle is sta- tionary
- the seat belts are pre-tensioned
The PRE-SAFE ®
PLUS braking application is can-
celled:
R if the accelerator pedal is depressed when a
gear is engaged
R if the risk of a collision passes or is no longer
detected
R if Distance Pilot DISTRONIC indicates an
intention to pull away
If the hazardous situation passes without result- ing in an accident, the original settings are
restored. Automatic measures after an acci-
dent
Immediately after an accident, the following
measures may be implemented, depending on
the type and severity of the impact:
R the hazard warning lamps are activated
R the emergency lighting is activated
R the vehicle doors are unlocked
R the front side windows are lowered
R vehicles with a memory function: the electri-
cally adjustable steering wheel is raised
R the engine is switched off and the fuel supply
is cut off
R vehicles with the Mercedes-Benz emergency
call system: automatic emergency call Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured in the front seats. For this reason, Mercedes-
Benz strongly advises that you fit a child
restraint system on a rear seat. Children are
generally better protected there.
If a child younger than twelve years old and
under 1.50 m in height is travelling in the vehi-
cle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
R be sure to observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's installation
instructions
R be sure to observe the instructions and safety
notes on the automatic front-passenger front
airbag deactivation system (Y page 50). Children in the vehicle

Driving tips
Changing gear The automatic transmission shifts to the indi-
vidual gears automatically when it is in trans-
mission position
D. Gearshifting is determined
by:
R the selected drive program
R the position of the accelerator pedal
R the road speed
Accelerator pedal position Your driving style influences how the automatic
transmission shifts gear:
R little throttle: early upshifts
R more throttle: late upshifts
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.
Gliding mode (diesel engines only) Gliding mode is characterised by the following:
R the combustion engine is disconnected from
the drive train
R the engine speed is equal to the engine idling
speed
R the gear indicated after the transmission
position Ddisappears in the multifunction
display (Y page 158)
Gliding mode can be activated and transmission
position Dshown in green under the following
conditions:
R you select the "ECO" setting for the drive sys-
tem within the Individualdrive program. You
can find information about this in the Digital
Owner's Manual

WARNING
Electrostatic charge can cause sparks and
thereby ignite fuel vapours. There is a risk of
fire and explosion.
Always touch the vehicle body before opening the fuel filler flap or touching the fuel pump
nozzle. This discharges any electrostatic
charge that may have built up. G
WARNING
Vehicles with a diesel engine:
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is a risk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, fuel can enter the fuel system.
Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. The repair costs are high. Notify a
qualified specialist workshop and have the
fuel tank and fuel lines drained completely.
! Do not use diesel to refuel vehicles with a
petrol engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system.
Even small amounts of the wrong fuel can
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Use a filter when adding fuel from a fuel can.
The fuel lines and/or the fuel injection system could otherwise be blocked by particles fromthe fuel can. Do not get back into the vehicle during the refu-
elling process, Otherwise, electrostatic charge
could build up again.
If you overfill the fuel tank, some fuel may spray out when you remove the fuel pump nozzle.

R
the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
The applicable permissible values, which must
not be exceeded, can be found:
R in your vehicle documents
R on the identification plates of the trailer tow
hitch and the trailer
R on the vehicle identification plate
If the values differ, the lowest value applies.
You will find the values approved by the manu-
facturer on the vehicle identification plates and
those for the towing vehicle under "Technical
data" (Y page 390).
When towing a trailer, your vehicle's handling
characteristics will be different in comparison to
when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradient-
climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R has a larger turning circle
This can impair the vehicle's handling charac-
teristics. Adapt your driving style accordingly.
Maintain a safe distance. Drive carefully.
When towing a trailer, always adjust your speed to the current road and weather conditions. Do
not exceed the maximum permissible speed for
your vehicle/trailer combination. Notes on towing a trailer
General notes !
If you have a trailer tow hitch retrofitted,
changes to the engine cooling system may be necessary, depending on the vehicle type.
If you have a trailer tow hitch retrofitted,
observe the anchorage points on the chassis.
Check the tyre pressures when towing a trailer.
You will find the values in the tyre pressure table in the vehicle fuel filler flap (Y page 364).Please note that when towing a trailer, the fol-
lowing driving systems have limited availability
or are not available at all.

R Blind Spot Assist (Y page 219)
R Active Lane Keeping Assist (Y page 224)
R Parking Pilot (Y page 204)
On vehicles without level control, the height of
the ball coupling will alter according to the load
placed on the vehicle. If necessary, use a trailer
with a height-adjustable drawbar.
You will find permissible trailer loads under
"Technical data" (Y page 390).
Driving tips Observe the information on ESP
®
trailer stabili-
sation (Y page 74) and on pulling away with a
trailer (Y page 151).
Select the Comfortdrive program using the
DYNAMIC SELECT controller (Y page 155).
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check the
trailer's documents to see what the maximum
permissible speed is for your trailer. Observe the legally prescribed maximum speed in the rele-
vant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissible rear axle load is increased
when towing a trailer. See the "Technical Data"
section to find out whether this applies to your
vehicle (Y page 390). If you utilise any of the
added maximum rear axle load when towing a
trailer, the vehicle/trailer combination may not
exceed a maximum speed of 100 km/h for rea-
sons concerning the operating permit. This also
applies in countries in which the permissible
maximum speed for vehicle/trailer combina-
tions is above 100 km/h.
When towing a trailer, your vehicle's handling
characteristics will be different to when driving
without a trailer and the vehicle will consume
more fuel.
Use the left-hand gearshift paddle to shift to a
lower gear on long and steep downhill gradients.
This also applies if you have activated cruise
control, the speed limiter or Distance Pilot
DISTRONIC.
This will use the braking effect of the engine, so
less braking will be required to maintain the
vehicle speed. This relieves the load on the 234

WARNING
A flat tyre severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of accident.
Tyres without run-flat characteristics:
R do not drive with a flat tyre.
R immediately replace the flat tyre with your
emergency spare wheel or spare wheel, or
consult a qualified specialist workshop.
Tyres with run-flat characteristics:
R pay attention to the information and warn-
ing notices on MOExtended tyres (tyres
with run-flat characteristics).
Accessories that are not approved for your vehi-
cle by Mercedes-Benz or are not being used cor- rectly can impair operating safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and enquire about:
R suitability
R legal stipulations
R factory recommendations Further information regarding wheels and tyres
can be found under "Wheel/tyre combinations"
(Y page 374).
You can ask for information regarding permitted
wheel/tyre combinations at a Mercedes-Benz
Service Centre.
Information on tyre pressure can be found:
R in the tyre pressure table in the fuel filler flap

shop. Operation
Information on driving
Check the tyre pressures when the vehicle is
heavily laden and adjust prior to a trip.
While driving, pay attention to vibrations, noises
and unusual handling characteristics, e.g. pull-
ing to one side. This may indicate that the
wheels or tyres are damaged. If you suspect that a tyre is defective, reduce your speed immedi-
ately. Stop the vehicle as soon as possible to
check the wheels and tyres for damage. Hidden tyre damage could also be causing the unusual
handling characteristics. If you find no signs of
damage, have the tyres and wheels checked at a
qualified specialist workshop.
When parking your vehicle, make sure not to
squash the tyre sidewalls. If it is necessary to
drive over kerbs, speed humps or similar eleva- tions, try to do so slowly and at an obtuse angle.
Otherwise, the tyres, particularly the sidewalls,
may be damaged. Regular checking of wheels and tyres
