Driving tips
General driving tips
Important safety notes
GWARNING
Always remember that you must concentrate
primarily on driving the vehicle. The driver's
concentration must always be directed
primarily at road traffic. For your own safety
and that of others, we recommend that you
stop the vehicle at a safe place and in
accordance with the traffic conditions before
making or accepting a phone call.
Comply with all legal requirements if you use
the telephone while driving. Use the hands-
free system and only use the telephone when
road, weather and traffic conditions permit. In
some jurisdictions, it is forbidden for drivers
to use mobile phones while driving.
Only operate COMAND (Cockpit Management
and Data System) in compliance with all legal
requirements and when the road, weather and
traffic conditions permit. You may otherwise
not be able to observe the traffic conditions,
endangering yourself and others.
Remember that your vehicle covers a distance
of 44 feet (approximately 14 m) a second
when it is traveling at only 30 mph
(approximately 50 km/h).
Drive sensibly – save fuel
Observe the following tips to save fuel:
XThe tires should always be inflated to the
recommended tire pressure.XRemove unnecessary loads.XRemove roof carriers when they are not
needed.XRemove basic carriers when they are not
needed.XWarm up the engine at low engine speeds.XAvoid frequent acceleration or braking.XHave all maintenance work carried out as
indicated by the service intervals in theService Booklet or by the service interval
display.
Fuel consumption also increases when
driving in cold weather, in stop-and-go traffic
and in mountainous terrain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment.
The possibility of a serious or even fatal
accident are greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Pedals
GWARNING
Make sure absolutely no objects are
obstructing the pedals' range of movement.
Keep the driver's footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure that the
pedals still have sufficient clearance.
During sudden driving or braking maneuvers,
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.
Rolling with the engine switched off
GWARNING
There is no power assistance for the steering
and the brake when the engine is not running.
Steering and braking requires significantly
more effort and you could lose control of the
vehicle and cause an accident as a result.
Do not turn off the engine while the vehicle is
in motion.

Displaying the coolant temperature
GWARNING
Driving when your engine is overheated can
cause some fluids which may have leaked into
the engine compartment to catch fire. You
could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until

Under normal driving conditions, with the
correct anti-corrosion and antifreeze additive
concentration, the reading may rise to
248 ‡(120 †).
! If the coolant temperature exceeds
248 ‡(120 †) do not continue driving. The
engine will otherwise be damaged.

Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and the child could be burned on these
parts.GWARNING
Never touch the heating element or sides of
the lighter; they are extremely hot. Hold the
knob only.
Make sure any children traveling with you do
not injure themselves or start a fire with the
hot cigarette lighter.
! The 12 V socket in the cigarette lighter
can be used for accessories (up to a
maximum of 180 W) as long as they have
the standard socket type for cigarette
lighters. Note that the socket in the
cigarette lighter can be damaged when
connecting accessories, for example by
frequent insertion and removal or by
sockets that do not fit correctly. A damaged
socket can cause the cigarette lighter to
stop working.
! The cigarette lighter in the center console
in the front compartment is not intended
for operating the tire inflation compressor.
XTurn the SmartKey to position 2 in the
ignition lock.XTo open: briefly press marking =.
Stowage compartment : opens.XPress in cigarette lighter ;.

automatically when the heating element is
red-hot.
12 V sockets
Points to observe before use
! The socket in the center console and the
socket in the cargo compartment are not
intended for operating the tire inflation
compressor.
The sockets can be used for accessories, e.
g. lamps or mobile phone chargers with a
maximum current draw of 180 W (15 A).
If you use the sockets for long periods when
the engine is switched off, the battery may
discharge.
XTurn the SmartKey to position 2 in the
ignition lock.
i You can also use the power sockets when
the SmartKey is in position 1 in the ignition
lock.
An emergency cut-out ensures that the on-
board voltage does not drop too low. If the
on-board voltage is too low, the power to
the sockets is automatically cut. This
ensures that there is sufficient power to
start the engine.

GWARNING
Any device that you connect must have a
suitable plug and meet U.S. standards. Never
pull at a cable to disconnect a plug from a
115 V AC power socket. Never use a damaged
connection cable. The 115 V AC power socket
must never be connected to another 115 V
AC power source. Do not use a converter with
an earthed plug for the 115 V AC power
socket. This could cause serious injury to you
and/or other people.
GWARNING
If the 115V AC socket is damaged or torn out
of the trim, do not use or touch the 115V AC
socket. Using a 115V AC socket that is
damaged or torn out of the trim could cause
serious personal injury to you and/or others.
115 V socket : provides an alternating
voltage of 115 V, so that small electronic
devices can be connected. These devices,
such as games consoles, chargers and
laptops, together should not consume more
than a maximum of 150 W.
Requirements for operation of these devices:
R the plug of the electronic device must be
inserted fully into 115 V power socket :.
R the maximum wattage of the device to be
connected must not exceed 150 W.
R the on-board power supply is within a
permissible volt range.
R the 12 V sockets in the rear and the cargo
compartment are operational
( Y page 285).
XOpen flap =.XInsert the plug of the electronic device into
115 V power socket :.
Indicator lamp ; lights up.
If indicator lamp ; does not light up,
consult the section on malfunctions.XTo turn off: disconnect the plug from 115 V
power socket :.
Ensure that you do not pull on the cord.XClose flap =.
Possible causes of malfunction:
R the on-board power supply is not within a
permissible volt range.
R the temperature of the DC/AC converter is
temporarily too high.
R some small electronic devices have a
constant nominal power of less than
150 W, but a very high inrush current.
These devices will not work. If you connect
such a device, 115 V power socket : will
not supply it with power.
If indicator lamp ; still does not light up,
contact a specialist workshop, e.g. an
authorized Mercedes-Benz Center.
