of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not

at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parking brake has not been fully
released when driving, the

parking brake can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only shift the automatic transmission to
the desired drive position when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery

Driving and parking Z

Drive sensibly – save fuel
Observe the following tips to save fuel:
X
The tires should always be inflated to the
recommended tire pressure.
X Remove unnecessary loads.
X Remove roof carriers when they are not
needed.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work performed at
the service intervals specified in the
Service Booklet or indicated
by the service
interval indicator.
Fuel consumption also increases when
driving in cold weather,
in stop-and-go traffic
and in mountainous terrain.
Drinking and driving G
WARNING
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 G
WARNING
Objects in the driver's footwell can restrict the
pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle
is jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the

pedals. Do not use
loose floormats. Exhaust check G
WARNING
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do not run the

engine in confined areas (such
as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are
entering the vehicle while driving, have the
cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with
the manufacturer's specifications. For this
reason, all work on the engine should only be
carried out by qualified and authorized
Mercedes-Benz technicians.
The engine settings must not be changed
under any circumstances. Furthermore, all
specific service work must be carried out at
regular intervals and in accordance with the
Mercedes-Benz service requirements. Details
can be found in the Maintenance Booklet. Braking

models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that
your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.

G
WARNING
The driver's concentration must always be
directed primarily at road traffic.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and

road conditions permit
it to be done safely.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 feet (approximately 14 m) per
second. G
WARNING
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see
information about your driving conditions,
such as
R speed
R outside temperature
R warning/indicator lamps
R malfunction/warning messages
R failure of any systems
Driving characteristics may be impaired. If you must continue to drive, do so with added
caution. Contact an authorized Mercedes-
Benz Center as soon as possible.
G
WARNING
Malfunction and warning messages are only
displayed for certain systems and are
intentionally not very detailed. The
malfunction and warning messages are
simply a reminder with respect to the
operation of certain systems. They do not
replace the owner's and/or driver's
responsibility to maintain the vehicle's
operating safety. Have all required
maintenance services and safety checks
performed on the vehicle.

Bring the vehicle to
an authorized Mercedes-Benz Center to
address the malfunction and warning
messages. G
WARNING
All categories of messages contain important
information which should be taken note of
and, where a malfunction is indicated,
addressed as soon as possible at an
authorized Mercedes-Benz Center.

when not in use. Otherwise, you could suffer
an electric shock and be seriously or even
fatally injured.
G
WARNING
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. G
WARNING
If the 115 V AC power socket is damaged or
pulled out of the

trim, do not use or touch the
115 V AC power socket. The use of a 115 V
AC power socket that has been damaged or
pulled out of the trim could cause serious
injury to you or others. 115 V power socket
0043 provides an AC
voltage of 115 V so that small electronic
devices can be connected. These devices,
such as games consoles, chargers and
laptops, should not consume more than a
maximum of 150 W altogether. Requirements for operation of these devices:
R
the 12 V sockets in the rear compartment
and the cargo compartment are
operational ( Y page 271).
R the plug of
the

electronic device is plugged
into 115 V power socket 0043.
R the on-board power supply is within a
permissible voltage range.
R the electronic device's maximum power
output does not exceed 150 W.
X Open flap 0087.
X Switch on the ignition.
X Insert the plug of the electronic device into
115 V power socket 0043.
Indicator lamp 0044 lights up.
If indicator lamp 0044 does not light up,
please read the section on malfunctions.
X To turn off: disconnect the plug from
115 V power socket 0043.
Ensure that you do not pull on the cord.
X Close flap 0087.
Possible causes of malfunctions:
R the on-board power supply is not within a
permissible voltage 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 switch-on current.
In that case, there is a possibility that these
devices will not function properly as 115 V
socket 0043 is not able to provide a high
enough current.
X If indicator lamp 0044 still does not light up,
contact a qualified specialist workshop. mbrace
