type and severity of the impact:
Rthe hazard warning lamps are activated
Rthe emergency lighting is activated

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 install a child
restraint system on a rear seat. Children are
generally better protected there.
If a child younger than twelve years and under
5 ft (1.50 m) in height is traveling in the vehicle:
Ralways secure this child in a restraint system
approved for Mercedes-Benz vehicles. The
child restraint system must be appropriate to
the age, weight and size of the child.
Rbe sure to observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's installation
instructions.
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
GWARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.

Important safety notes
GWARNING
When leaving the vehicle, always remove the
SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system, and do not give them access to an unlocked vehicle. A child's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. They could:
Rinjure themselves on vehicle parts
Rbe seriously or fatally injured by extreme
heat or cold
Rinjure themselves or have an accident with
vehicle equipment that may still be in oper-
ation even after the SmartKey has been
removed from the ignition, such as the seat
adjustment, steering wheel adjustment or
memory function.
If children open a door, they could cause
severe or even fatal injury to other persons; if they get out of the vehicle, they could injure
themselves when doing so or be seriously or
even fatally injured by any passing traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and a child could be burned on these
parts.
GWARNING
Do not carry heavy or hard objects in the
passenger compartment or cargo compart-
ment unless they are firmly secured in place.
Unsecured or improperly positioned cargo
increases a child's risk of injury in the event of
Rstrong braking maneuvers
Rsudden changes of direction
Ran accident
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the rear
door is open when the engine is running, par-
ticularly if the vehicle is moving, exhaust
fumes could enter the passenger compart-
ment. There is a risk of poisoning.
Turn off the engine before opening the rear
door. Never drive with the rear door open.
!The tailgate swings out to the side when
opened. Therefore, make sure that there is
sufficient clearance.
iDo not leave the SmartKey in the cargo
compartment. Otherwise, you could lock
yourself out.

Hill start assist
GWARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist helps you when pulling away for-
wards or in reverse on an uphill gradient. It holds
the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and to
depress it before the vehicle begins to roll.
XTake your foot off the brake pedal.
iOnce you have taken your foot off the brake
pedal, the vehicle is held for around one sec-
ond.

ECO start/stop function
Important safety notes
GWARNING
If the engine is switched off automatically and
you exit the vehicle, the engine is restarted
automatically. The vehicle may begin moving.
There is a risk of accident and injury.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.
General notes
The ECO start/stop function switches the
engine off automatically when the vehicle stops
moving.
The engine starts automatically when the driver
wants to pull away again. The ECO start/stop
function thereby helps you to reduce the fuel
consumption and emissions of your vehicle.
The ECO start/stop function is activated each
time the engine is switched on.
The ECO start/stop function is only available in
drive program C/E.
The system is operational if all conditions for
automatic engine switch-off have been fulfilled
(
Ypage 115) and the èsymbol is shown in
green in the multifunction display.
In addition, the Stop/Start active
message
is shown in the AMG menu in the multifunction
display.
If not all conditions for automatic engine switch-
off are fulfilled (
Ypage 115), the èECO
symbol is shown in yellow in the multifunction
display.
In addition, the Stop/Start inactive
mes-
sage is shown in the AMG menu in the multi-
function display.
If the ECO start/stop function has been man-
ually deactivated (
Ypage 114) or a malfunction
has caused the system to be deactivated, the
