39 Getting started
Unlocking
SmartKey with KEYLESS-GO*
Vehicles equipped with the KEYLESS-GO
feature are supplied with a SmartKey with
integrated KEYLESS-GO function and a re-
movable KEYLESS-GO start / stop button.
With the KEYLESS-GO start/stop button
inserted and the SmartKey with
KEYLESS-GO present in the vehicle, press-
ing the KEYLESS-GO start/stop button

without the brake pedal depressed
corresponds to the various starter
switch positions (
page 40)


with the brake pedal firmly depressed
will start the engine (
page 54)
If you wish or should there be a need to in-
sert the SmartKey with KEYLESS-GO in the
starter switch, the KEYLESS-GO start/stop
button can be easily removed by pulling it
out of the starter switch.
!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 487).


Get a jump start (
page 496).
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 KEYLESS-GO start/stop button
does not need to be removed from the
starter switch when you leave the vehi-
cle. However, always take the
SmartKey with KEYLESS-GO with you
when you leave the vehicle. As long as
the SmartKey with KEYLESS-GO is in
the vehicle, the vehicle’s electrical sys-
tems can be switched on or the engine
can be started using the KEYLESS-GO
start/stop button.

55 Getting started
Driving

Press KEYLESS-GO start / stop
button1 once.
The engine starts if the SmartKey with
KEYLESS-GO is in the vehicle.
For information on turning off the engine
with KEYLESS-GO, see “Turning off with
KEYLESS-GO*” (
page 66).Starting 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:

Remove KEYLESS-GO start / stop
button from starter switch.

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 54). Remember that extended
starting attempts can drain the battery.

Get a jump start (
page 496).
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
Light Truck Center.
iIf you wish to start the vehicle using the
SmartKey instead of the KEYLESS-GO
feature, remove the KEYLESS-GO
start/stop button from the starter
switch (
page 40).

316 Controls in detailUseful featuresThe Mercedes-Benz Roadside Assistance
dispatcher will either dispatch a qualified
Mercedes-Benz technician or arrange to
tow your vehicle to the nearest
Mercedes-Benz Light Truck Center. For
services such as labor and/or towing,
charges may apply. Refer to the Roadside
Assistance Manual for more information.
These programs are only available in the
USA:

Sign and Drive services: Services such
as jump start, a few gallons of fuel or
the replacement of a flat tire with the
vehicle spare tire are obtainable.
iThe indicator lamp on the Roadside
Assistance button• remains illumi-
nated in red for approximately
10 seconds during the system
self-check after switching on the igni-
tion (together with the SOS button and
the Information button¡).
See system self-check (
page 312) if
the indicator lamp does not come on in
red or stays on longer than
approximately 10 seconds.
If the indicator lamp on the Roadside
Assistance button• is flashing
continuously and there was no voice
connection to the Response Center
established, then the Tele Aid system
could not initiate a Roadside Assis-
tance call (e.g. the relevant cellular
phone network was not available). The
message
Call failed
appears in the
multifunction display.
Roadside Assistance calls can be
terminated using thet button on
the multifunction steering wheel or the
END Button on the Modular COMAND
System.

488 Practical hintsBattery
!
The battery is a valve-regulated lead
acid (VRLA) battery, also referred to as
“fleece” battery. Such batteries do not
require topping-up of the electrolyte
level. VRLA batteries therefore do not
have cell caps and the battery cover is
non-removable. Do not attempt to
open the battery as otherwise the bat-
tery will be damaged.
Even though VRLA batteries do not
require topping-up of the electrolyte
level and cannot be opened to check
the electrolyte level, the battery condi-
tion must be checked periodically by
performing a battery conductance test.
Refer to Maintenance Booklet for bat-
tery condition testing intervals.
As with any other battery, the battery
may discharge if the vehicle is not
operated for an extended period of
time. You can connect a battery
maintenance charge unit tested and
approved for use on your vehicle model
or disconnected the battery to prevent
battery discharge. Contact an
authorized Mercedes-Benz Light Truck
Center for more information.
!The factory-equipped VRLA battery is
leak-proofed. Only use a battery as re-
placement that has the same security
features and is of identical size,
voltage, and capacity as the
factory-equipped battery.
The battery, the battery ventilation and
the lateral plug must always be
securely installed when the vehicle is in
operation.Warning!
G
Jump starting must only be done using the
jump-start contacts located in the engine
compartment (
page 496).

489 Practical hints
Battery
Disconnecting, removing, reinstalling and reconnecting the battery
Warning!
G
Failure to follow these instructions can re-
sult in severe injury or death.
Observe all safety instructions and precau-
tions when handling automotive batteries
(page 487).
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.
!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 Light
Truck Center.
Contact your authorized
Mercedes-Benz Light Truck Center for
further information.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.
Warning!
G
Disconnecting, removing, reinstalling and
reconnecting the battery is a complicated
and technically demanding procedure that
also requires safety precautions to avoid the
risk of injury. We strongly recommend that it
be performed by a qualified technician or an
authorized Mercedes-Benz Light Truck
Center only. Please read the instructions
fully before beginning operation and only
undertake it if you feel fully capable of per-
forming all of the tasks involved as de-
scribed in these instructions. Observe all
safety instructions and precautions when
handling automotive batteries
(page 487). Performing the tasks involved
incorrectly can cause damage to the vehicle
and impair the operating safety of the
vehicle, and/or cause severe injury to you
or others.

iWith a disconnected battery you will no
longer be able to turn the SmartKey in
the starter switch and pressing the
KEYLESS-GO* start/stop button will
have no effect.iIf your battery is discharged, the vehi-
cle must be jump started (
page 496)
using the jump start contacts in the
engine compartment, or an accessory
battery charge unit* approved by
Mercedes-Benz must be connected
using the jump start contacts in the
engine compartment (see separate
instructions for the accessory battery
charge unit*) before any of the follow-
ing steps can be performed. If the bat-
tery cannot be jumped or charged,
please contact an authorized
Mercedes-Benz Light Truck Center.
iOpen doors only when conditions are
safe to do so.
