Locking and unlocking
Automatic central locking
The doors and the trunk automatically lock
when the ignition is switched on and the
wheels are turning at vehicle speeds of
approximately 9 mph (15 km/h).
You can open a locked door from the in-
side. Open door only when conditions are
safe to do so.
You can deactivate the automatic locking
using the control system, see “Setting
automatic locking” (
page 141).
Locking and unlocking from the inside
You can lock or unlock the doors and the
trunk from inside using the central locking
switch. This can be useful, for example, if
you want to lock the vehicle before starting
to drive.
The fuel filler flap will not be locked or un-
locked with the central locking or unlock-
ing switch, respectively.
iIf the vehicle has previously been cen-
trally locked from the outside with the
SmartKey, opening the trunk from the
inside will trigger the anti-theft alarm
system.
To cancel the alarm, do one of the fol-
lowing:
Press buttonŒor‹ on the
SmartKey.
Insert the SmartKey in the starter
switch.
iThe doors unlock automatically after an
accident if the force of the impact ex-
ceeds a preset threshold.
To prevent the vehicle door locks from
locking, deactivate the automatic cen-
tral locking when the vehicle
is pushed or towed
is on a test stand
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Unsuper-
vised use of vehicle equipment may cause
an accident and/or serious personal injury.

Switching off cornering fog lamps
The combination switch for the turn signal
resets automatically after major steering
wheel movements. This will switch off the cornering fog lamps if they where activat-
ed by switching on the left or right turn
signal.
If the turn signal should stay on after mak-
ing the turn, the turn signal and cornering
fog lamp can be switched off by returning
the combination switch to its original
position.

available at a vehicle speed above
25 mph (40 km/h).
iThe cornering fog lamps will come on
automatically depending on the
steering angle, even if you did not
switch on either turn signal.
If the cornering fog lamps came on
automatically, they will also go out au-
tomatically depending on the steering
angle.

116 Controls in detailInstrument clusterOutside temperature indicator
The outside temperature is displayed in
the multifunction display (
page 123).
For information on selecting the tempera-
ture display unit, i.e. degrees Celsius (°C)
or degrees Fahrenheit (°F), see “Selecting
temperature display mode” (page 131).The temperature sensor is located in the
front bumper area. Due to its location, the
sensor can be affected by road or engine
heat during idling or slow driving. There-
fore, the accuracy of the displayed temper-
ature can only be verified by comparison to
a thermometer placed next the sensor, not
by comparison to external displays, e.g.
bank signs, etc.
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature displays caused by heat radiated
from the engine during idling or slow driv-
ing.
Trip odometer
Make sure you are viewing the stan-
dard display menu (
page 122).
Press and hold reset buttonJuntil
the trip odometer is reset.
Clock
Vehicles with COMAND*:
The clock in the instrument cluster can be
synchronized with the time set in
COMAND using the time synchronization
with head unit feature (
page 133), or set
independently from COMAND using the
control system (
page 134) with the time
synchronization with head unit feature set
to
Off
.
For setting the time in COMAND, see sep-
arate COMAND operating instructions.
For setting the time with audio system,
(
page 134).
Warning!
G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
