When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment may cause an accident
and/or serious personal injury.
37 Getting started
Unlocking
For information on starting the engine
using the SmartKey, see “Starting with the
SmartKey” (
page 50).SmartKey with KEYLESS-GO*
Pressing the KEYLESS-GO start/stop but-
ton on the gear selector lever corresponds
to turning the SmartKey to the various
starter switch positions.
If you firmly depress the brake pedal dur-
ing pressing the KEYLESS-GO start/stop
button, the engine starts automatically.
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. The indicator and warning lamps
(except low beam headlamp indicator
lamp, high beam headlamp indicator
lamp, and turn signal indicator lamps if
activated) should go out when the en-
gine is running. This indicates that the
respective systems are operational.iThe SmartKey can only be removed
from the starter switch with the gear
selector lever in position P.
!If the SmartKey cannot be turned in the
starter switch, the starter battery may
not be sufficiently charged.
Check the battery and charge it if
necessary (
page 429).
Get a jump start (
page 456).
To prevent accelerated battery dis-
charge or a completely discharged bat-
tery, always remove the SmartKey from
the starter switch when the engine is
not in operation.
iThe function of the SmartKey overrules
the KEYLESS-GO function.

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.
Have the problem repaired by an
authorized Mercedes-Benz Center as
soon as possible.
The coolant temperature is above
248°F (120°C)
The coolant is too hot and is no longer
cooling the engine.
Stop the vehicle as soon as possible in
a safe location and turn off the engine.
Allow engine and coolant to cool.
Check the coolant level and add cool-
ant if necessary (
page 321).In case of accident
If the vehicle is leaking fuel:
Do not start the engine under any cir-
cumstances.
Notify local fire and/or police authori-
ties.
If the extent of the damage cannot be de-
termined:
Notify an authorized Mercedes-Benz
Center.
If no damage can be determined on the
major assemblies
fuel system
engine mount:
Start the engine in the usual manner.
66 Safety and SecurityOccupant safetyIn this section you will learn the most
important facts about the restraint system
components of the vehicle.
Seat belts (
page 72)
Child restraints (
page 78)
Lower anchors and tethers for children
(LATCH) (
page 88)
Supplemental Restraint System (SRS) with
Air bags (
page 67)
Air bag control unit (with crash
sensors)
Emergency tensioning device (ETD) for
seat belts (

Air bag system components with
75indicator lamp
(page 84)
Front passenger seat with Occupant
Classification System (OCS)
(page 81)
As independent systems, their protective
functions work in conjunction with each
other. The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates early detection of malfunctions.
The
1
indicator lamp in the instrument
cluster lights up when the ignition is
switched on and goes out no later than a
few seconds after the engine has been
started.
The SRS components are in operational
readiness if the
1
indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the
1
indicator lamp:
fails to go out after approximately
4 seconds after the engine was started
does not come on at all
comes on after the engine was started
or while driving
iFor information on infants and children
traveling with you in the vehicle and
restraint systems for infants and chil-
dren, see “Children in the vehicle”
(page 77).
Warning!
G
In the event that the 1 indicator lamp
comes on during driving or does not come
on at all, the SRS self-check has detected a
malfunction. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Center immediately to have
the system checked; otherwise the SRS may
not be activated when needed in an acci-
dent, which could result in serious or fatal
injury, or it might deploy unexpectedly and
unnecessarily which could also result in
injury.
In addition, improper repair work on the SRS
creates a risk of rendering the SRS inopera-
tive or causing unintended air bag deploy-
ment. Work on the SRS must therefore only
be performed by qualified technicians. Con-
tact an authorized Mercedes-Benz Center.
98 Safety and SecurityDriving safety systems
The electrohydraulic brake servo assis-
tance switches off automatically
approximately 2 minutes after you
turned the SmartKey in the starter
switch to position0 or removed the
SmartKey
approximately 2 minutes after you
pressed the KEYLESS-GO* start/stop
button to turn off the engine or power
supply and opened the driver’s door
(with driver’s door open, the starter
switch is set to position 0, same as
SmartKey removed from starter
switch)
approximately 20 seconds after you
locked the vehicle from outside
iIf the electrohydraulic brake system is
activated as the brake pedal is first de-
pressed, you may feel a reduced pedal
resistance and longer pedal travel than
normal. When releasing the pedal, you
may also feel the brake pedal pulsate
and you may hear a sound which is
caused by the activation of the electro-
hydraulic brake system pump. This is
normal and not an indication of a mal-
function. Pedal travel returns to normal
when you release the brake pedal and
the sound soon ceases.
If you experience the above while driv-
ing and the red brake warning lamp
(page 374) illuminates and/or warn-
ing messages appear in the instrument
cluster (
page 383), the brake system
is malfunctioning. Follow the instruc-
tions of the warning message(s) and
have the brake system checked imme-
diately.
Warning!
G
Have brake pad replacement and other work
on the electrohydraulic brake system car-
ried out by qualified technicians only. Con-
tact an authorized Mercedes-Benz Center
for further information. The electrohydraulic
brake system must be deactivated prior to
working on the system. High pressure is in-
termittently built up in the system as part of
its automatic self-test. In addition, the sys-
tem is automatically activated when the ve-
hicle is unlocked by SmartKey, when the
driver or passenger door is opened, when
the starter switch is turned to position
1,
when the brake pedal is depressed or when
the parking brake is released. Failure to de-
activate the system prior to maintenance
will cause brake pistons to extend and brake
fluid to leak, which may result in injuries
(contusions and acid burns). Extended
brake pistons may also cause injury.
