KEYLESS-GO start/stop button1USA only
2Canada only
The SmartKey with KEYLESS-GO must be
located in the vehicle.
Make sure the gear selector lever is set
toP.
Do not depress the brake pedal.
!If the SmartKey cannot be turned in the
starter switch, the vehicle battery may
not be sufficiently charged.
Check the vehicle battery and
charge it if necessary (
page 391).
Get a jump start (
page 394).
To prevent accelerated vehicle battery
discharge or a completely discharged
vehicle battery, 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.
50 Getting startedDrivingStarting difficulties
If the engine does not start as described,
carry out the following steps:
If you are starting the engine with the
SmartKey: Turn SmartKey in starter
switch to position0 and repeat starting
procedure.
If you are starting the engine with
KEYLESS-GO*: Close any doors that
may be open to allow for better detec-
tion of the SmartKey with
KEYLESS-GO*.
or
Start the engine with the SmartKey as
radio signals from another source may
be interfering with the SmartKey with
KEYLESS-GO*.
Repeat the starting procedure
(page 48). Remember that extended
starting attempts can drain the vehicle
battery.
Get a jump start (
page 394).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.

will transmit data generating the vehicle
identification number, model, color and lo-
cation (subject to availability of cellular
and GPS signals).
A voice connection between the Roadside
Assistance dispatcher and the occupants
of the vehicle will be established.
Describe the nature of the need for as-
sistance.The Mercedes-Benz Roadside Assistance
dispatcher will either dispatch a qualified
Mercedes-Benz technician or arrange to
tow your vehicle to the nearest authorized
Mercedes-Benz Center. For services such
as labor and/or towing, charges may ap-
ply. Refer to the Roadside Assistance

when the indicator lamp does not come
on in red or stays on longer than ap-
proximately 10 seconds.
If the indicator lamp in the Roadside
Assistance button• is flashing con-
tinuously and no voice connection to
the Response Center was established,
the Tele Aid system could not initiate a
Roadside Assistance call (e.g. the rele-
vant cellular phone network is not
available). The message CALL FAILED
appears in the multifunction display.

Failure to follow these instructions can re-
sult in severe injury or death.
Never lean over batteries while connecting,
you might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.Warning!
G
Do not place metal objects on the battery as
this could result in a short circuit.
Use leak-proof battery only to avoid the risk
of acid burns in the event of an accident.
!Never loosen or detach battery termi-
nal clamps while the engine is running
or the SmartKey is in the starter switch.
Otherwise the alternator and other
electronic components could be se-
verely damaged.
Have the battery checked regularly by
an authorized Mercedes-Benz Center.
Refer to Maintenance Booklet for main-
tenance intervals or contact your au-
thorized Mercedes-Benz Center for
further information.Warning!

394 Practical hintsJump starting
If the battery is discharged, the engine can
be started with jumper cables and the bat-
tery of another vehicle. Observe the follow-
ing:
Jump starting should only be performed
when the engine and catalytic convert-
er are cold.
Do not start the engine if the battery is
frozen. Let the battery thaw out first.
Only use 12-volt battery to jump start
your vehicle. Jump starting with a more
powerful battery could damage the ve-
hicle’s electrical system, which will not
be covered by the Mercedes-Benz
Limited Warranty.
Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.
Always make sure that the jumper ca-
bles are not on or near pulleys, fans or
other parts that move when an engine
is started or running.
Warning!
G
Failure to follow these directions will cause
damage to the electronic components, and
can lead to a battery explosion and severe
injury or death.
Never lean over batteries while connecting
or jump starting, you might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water, and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and very explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.
Attempting to jump start a frozen battery
can result in it exploding, causing personal
injury.
Read all instructions before proceeding.
!Avoid repeated and lengthy starting at-
tempts.
Do not attempt to start the engine us-
ing a battery quick charge unit.
If engine does not run after several un-
successful starting attempts, have it
checked at the nearest authorized
Mercedes-Benz Center.
Excessive unburned fuel generated by
repeated failed starting attempts may
damage the catalytic converter and
may present a fire risk.
Make sure the jumper cables do not
have loose or missing insulation.
Make sure the cable clamps do not
touch any other metal part while the
other end is still attached to a battery.!Do not tow-start the vehicle.
