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:

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.
Unlocking the liftgate

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.

cluster displayPractical hints Car care Index 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 buttonŒ.
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.

Automatic (optional on ML 320):
With the key in steering lock position 2 and the
automatic antiglare function activated, the mirror
reflection brightness responds to changes in light
sensitivity.
To a ctiva te:
Press button (1). The green indicator lamp in the rear
view mirror lights up.To deactivate:
Press button (1) again. The indicator lamp in the rear
view mirror goes out. The mirror brightness does not
respond to changes in light sensitivity.
Notes:
With gear selector lever in position “R”, or with the
interior lamps (except cargo compartment lamp)
switched on, the mirror brightness does not respond to
changes in light sensitivity.
The automatic antiglare function does not react, if
incoming light is not aimed directly at sensors in the
mirror.
Wa r n i n g !
In the case of an accident liquid electrolyte may
escape the mirror housing when the mirror glass
breaks.Electrolyte has an irritating effect. Do not allow the
liquid come into contact with eyes, skin, clothing,
or respiratory system. In cases it does, immediately
flush affected area with water, and seek medical
help if necessary.

166 Automatic transmission
Te ch n ica l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index
Driving
The selector lever is automatically locked while in
position “P”. To move the selector lever out of
position “P”, the service brake pedal must be firmly
depressed before the shift lock will release.
Shift selector lever to the desired position only when the
engine is idling normally and the service brake is
applied. Do not release the brake until ready to drive.
The vehicle may otherwise start creeping when the
selector lever is in drive or reverse position.Important!
After selecting any driving position from “N” or “P”,
wait a moment to allow the gear to fully engage before
accelerating, especially when the engine is cold.
Accelerator position
Partial throttle = early upshifting = normal acceleration
Full throttle = later upshifting = rapid acceleration
Kickdown (depressing the accelerator beyond full
throttle) = downshifting to a lower gear = maximum
acceleration. Once the desired speed is attained, ease up
on the accelerator – the transmission shifts up again.
Stopping
For brief stops, e.g. at traffic lights, leave the
transmission in gear and hold vehicle with the service
brake.
For longer stops with the engine idling, shift into “N”
or “P” and hold the vehicle with the service brake.
When stopping the vehicle on an uphill gradient, do not
hold it with the accelerator, use the brake. This avoids
unnecessary transmission heat build up.
Wa r n i n g !
It is dangerous to shift the selector lever out of “P”
or “N” if the engine speed is higher than idle speed.
If your foot is not firmly on the brake pedal, the
vehicle could accelerate 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.

The switch is located in the instrument panel.
Important!
When switching to or from the LOW RANGE mode,
observe the following:
•The vehicle must be at a complete standstill.
•The engine speed must not exceed 1500 rpm.Failure to do so may result in transmission / engine
damage not covered by the Mercedes-Benz Limited
Warranty
The LOW RANGE mode should be switched on:
•during off-road driving,
•when crossing waters.
For additional practical hints refer to off-road driving
on page 183.
Switching on:
1. Sto p t h e v e h i c l e .
2. Move transmission selector lever to position “N”.
3. Push top end of switch. The LOW RANGE indicator
lamp in the instrument cluster blinks slowly during
the changeover.
Once the changeover is complete, the indicator lamp in
the instrument cluster lights up continuously.
Note:
If the indicator lamp blinks fast, one or more switching
conditions were not observed, or the LOW RANGE mode
is defective.
