If necessary, move steering wheel
slightly to allow the locking mechanism
to engage.
1Power supply to some electrical con-
sumers, such as seat adjustment2Ignition (power supply for all electrical
consumers) and driving position. All
lamps (except low beam headlamp in-
dicator lamp, high beam headlamp indi-
cator lamp, and turn signal indicator
lamps unless activated) in the instru-
ment cluster come on. If a lamp in the
instrument cluster fails to come on
when the ignition is switched on, have
it checked and replaced if necessary. If
a lamp in the instrument cluster re-
mains on after starting the engine or
comes on while driving, refer to “Lamps
in instrument cluster” (

iWhen you switch on the ignition, the in-
dicator and warning lamps (except low
beam headlamp indicator lamp, high
beam headlamp indicator lamp, and
turn signal indicator lamps unless acti-
vated) in the instrument cluster come
on. This indicates that the respective
systems are operational. The indicator
and warning lamps (except low beam
headlamp indicator lamp, high beam
headlamp indicator lamp, and turn sig-
nal indicator lamps if activated) should
go out when the engine is running.iVehicles with automatic transmission:
The SmartKey can only be removed
from the starter switch with the gear
selector lever in positionP.
!If the SmartKey cannot be turned in the
starter switch, the battery may not be
sufficiently charged.
Check the battery and charge it if
necessary (
page 401).
Get a jump start (
page 404).
To prevent accelerated battery dis-
charge and a possible dead battery, al-
ways remove the SmartKey from the
starter switch when the engine is not in
operation.

Make sure the gearshift lever is in neu-
tral position (no gear selected).
Fully depress clutch pedal.
Otherwise the engine cannot be start-
ed due to the integrated safety inter-

Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas
(such as garage) which are not properly ven-
tilated. If you think that exhaust gas fumes
are entering the vehicle while driving, have
the cause determined and corrected imme-
diately. If you must drive under these condi-
tions, drive only with at least one window
fully open.

If the engine does not start as described,
carry out the following steps:
Turn SmartKey in starter to position0
and repeat starting procedure.
Remember that extended starting
attempts can drain the battery.
Get a jump start (
page 404).
If the engine does not start after several
starting attempts, there could be a mal-
function in the engine electronics or in the
fuel supply system.
Notify an authorized Mercedes-Benz
Center.
iYou can also use the “touch-start”
function. Turn the SmartKey to

When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could release the parking brake, which
could result in an accident and/or serious
injury.
iVehicles with automatic transmission*:
Wait for the gear selection process to
complete before setting the vehicle in
motion.
iYou can open a locked door from the
inside. Open doors only when condi-
tions are safe to do so.
You can deactivate the automatic lock-
ing using the control system
(page 148).
!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.!If you hear a warning signal when driv-
ing off, you have forgotten to release
the parking brake.
Release the parking brake.

After a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter to reach
its operating temperature earlier.
For more information on driving, see “Driv-
ing instructions” (
page 277).
Switching on headlamps
For more information on headlamps, see
“Lighting” (
page 110).

Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.!Vehicles with automatic transmission*:
Place the gear selector lever in
positionP or R only when the vehicle is
stopped in order to avoid damaging the
transmission.
!Do not run cold engine at high engine
speeds. Running a cold engine at high
speeds may shorten the service life of
the engine.Warning!
G
Vehicles with automatic transmission*: It is
dangerous to shift the gear selector lever
out ofP or N if the engine speed is higher
than idle speed. If your foot is not firmly on
the brake pedal, the vehicle could acceler-
ate quickly forward or in reverse. You could
lose control of the vehicle and hit someone
or something. Only shift into gear when the
engine is idling normally and when your right
foot is firmly on the brake pedal.

setting.
Vehicles with rain sensor*:
Intermittent wiping interval is depen-
dent on wetness of windshield. After
the initial wipe, pauses between wipes
are automatically controlled by the rain
sensor.
!Vehicles with rain sensor*:
Do not leave windshield wipers in inter-
mittent setting when the vehicle is tak-
en to an automatic car wash or during
windshield cleaning. Wipers will oper-
ate in the presence of water sprayed on
the windshield, and wipers may be
damaged as a result.
The switch should not be left in inter-
mittent setting as the wipers will wipe
the windshield once every time the
engine is started. Dust that accumu-
lates on the windshield might scratch
the glass and/or damage the wiper
blades when wiping occurs on a dry
windshield.

Problems while driving
The engine runs erratically and misfires
An ignition cable may be damaged.
The engine electronics may not be
operating properly.
Unburned gasoline may have entered
the catalytic converter and damaged it.
Give very little gas.

authorized Mercedes-Benz Center as
soon as possible.The coolant temperature is over 248°F
(120°C)
The coolant is too hot and is no longer
cooling the engine.
Stop the vehicle as soon as possible
and turn off the engine. Allow engine
and coolant to cool.
Check the coolant level and add cool-
ant if necessary (
page 296).In case of accident
If the vehicle is leaking gasoline:
Do not start the engine under any cir-
cumstances.
