Proceed as follows:
1. Position the vehicle with the charged battery so that
the jumper cables will reach, but never let the
vehicles touch. Make sure the jumper cables do not
have loose or missing insulation.
2. On both vehicles:
•Turn off engine and all lights and accessories,
except hazard warning flashers or work lights.
•Apply parking brake and shift selector lever to
position “P”.
Important!
3. Clamp one end of the first jumper cable to the
positive (+) under hood terminal of the discharged
battery and the other end to the positive (+) terminal
of the charged battery. Make sure the cable clamps
do not touch any other metal parts.
4. Clamp one end of the second jumper cable to the
grounded negative (–) terminal of the charged
battery and the final connection to the negative (–)
terminal of the discharged battery.Important!
5. Start engine of the vehicle with the charged battery
and run at high idle. Make sure the cables are not
on or near pulleys, fans, or other parts that move
when the engine is started. Allow the discharged
battery to charge for a few minutes. Start engine of
the disabled vehicle in the usual manner.
6. After the engine has started, remove jumper cables
by exactly reversing the above installation
sequence, starting with the last connection made
first. When removing each clamp, make sure that it
does not touch any other metal while the other end
is still attached.
Notes:
If engine does not run after several unsuccessful
starting attempts, have it checked at the nearest
authorized Mercedes-Benz Light Truck Center.
Excessive unburned fuel may damage the catalytic
converter.

Locking:
Press transmit button ‹ once. All turn signal lamps
blink three times to indicate that the vehicle is locked
and the antitheft alarm is activated.
Notes:
If the turn signal lamps do not blink three times when
locking the vehicle, a door, the liftgate, or the hood is
not properly closed. Close the respective element and
lock the vehicle again with the remote control.
If the vehicle cannot be locked or unlocked by pressing
the transmit button, then it may be necessary to change
the batteries in the remote control or to synchronize the
remote control, see page 270 and page 271.

Notes:
If doors are unlocked with the central locking switch
after activating the automatic central locking, and
neither door is opened, then the doors remain unlocked
even at vehicle speeds of approximately 9 mph
(15 km / h) or more.
If a door is opened from the inside at speeds of
approximately 9mph (15km/h) or less with the
automatic central locking activated, the door will again
be automatically locked at speeds of approximately
9 mph (15 km / h) or more.
Important!
When towing the vehicle, or with the vehicle on a
dynamometer test stand, please, note the following:
With the engine running, the vehicle doors will lock if
the left front wheel spins at vehicle speeds of
approximately 9 mph (15 km / h) or more.
To prevent vehicle door locks from locking, deactivate
the automatic central locking. Emergency unlocking in case of accident
The doors unlock automatically a short time after an
accident in which an airbag or emergency tensioning
retractor deploys (this is intended to aid rescue and
exit). However, the key must still be in the steering lock
position 1 or 2.
Additionally the hazard warning flashers turn on
automatically and the interior lights switch on for
approximately 30 minutes.

Antitheft alarm system
The indicator lamp is located in the center console.
The antitheft alarm is automatically armed or disarmed
with the remote control by locking or unlocking the
vehicle.
The antitheft alarm is armed within approximately
15 seconds after locking the vehicle with the remote
control.
A blinking lamp in the center console indicates that the
alarm is armed.
Notes:
Use of the key in the front door locks does not arm or
disarm the antitheft alarm system.
The alarm sounds when unlocking the driver’s door
with the mechanical key. Cancel alarm by turning key in
steering lock to position 1, or with the remote control by
pressing button Œ.
If the vehicle battery voltage falls below 10 volts, the
alarm is automatically canceled and the antitheft alarm
system is disarmed. When the voltage is above this
value again, the antitheft alarm system is armed again. Operation:
Once the alarm system has been armed, the turn signal
lamps will flash rapidly (approximately 3 minutes) and
the horn will sound intermittently (approximately
30 seconds) when someone:
• opens a door,
• opens the liftgate,
• opens the hood,
• breaks a window,
• attempts to raise the vehicle.
The alarm will stay on even if the activating element (a
door, for example) is immediately closed.
If the alarm stays on for more than 20 seconds, an
emergency call is initiated automatically. See Tele Aid
on page 148.
Note:
The alarm system will cycle three times when triggered.
The interior lights are automatically switched on when
the alarm comes on and go out when canceling the
alarm.
