when the battery is dead or disconnected or
when there is an electrical malfunction, the
transmission lock must be released manually;
otherwise, the rear wheels are locked and the
vehicle cannot be towed.
Step on the brake when manually unlock-
ing the transmission lock; otherwise,
there is a danger of the vehicle rolling.<
The transmission lock should only be released
for towing. Reengage the transmission lock
after parking the vehicle at its destination.
If it also becomes necessary to manually
release the parking brake, follow this sequence:
1.Start by manually releasing the parking
brake, refer to page60.

during periods when the vehicle is stored with
the battery disconnected or the battery switch
in the OFF position.
It is therefore important, independent of the dis-
play, to change the brake fluid at least every
2years.
The same is true for other time-dependent
maintenance procedures.<

Parking lamps/low beams

1Parking lamps and daytime running lamps*
2Low beams
3Automatic headlamp control, daytime run-
ning lamps
* and Adaptive Head Light*
If you open the driver's door when the ignition is
switched off, then the exterior lighting is
switched off if the light switch is in position0, 2
or3.
Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps for parking.
The parking lamps drain the battery. Do
not leave them switched on for long peri-
ods of time; otherwise, it may no longer be pos-
sible to start the engine. It is preferable to
switch on the left-hand or right-hand roadside
parking lamps, refer to page101.<
Low beams
The low beams light up when the light switch is
in position 2 and the ignition is on.
Automatic headlamp control
In the switch position3, the system activates
the low beams and switches them on or off in
response to changes in ambient light condi-
tions, for example in a tunnel, at dawn and dusk,
and in case of precipitation. The LED next to the symbol is illuminated when the low beams are
on.
The low beams may be switched on when the
sun is low on the horizon in a clear sky.
The low beams remain switched on
regardless of the ambient light when you
switch on the front fog lamps.<
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the sensors
cannot detect fog or hazy weather. To avoid
safety risks, you should always switch on the
lamps manually under these conditions.<
Pathway lighting
After parking the vehicle and switching off the
headlamps, you can use the headlamp flasher
control to activate the low beams for a period of
roughly 40 seconds.
Pressing the button on the remote control,
refer to page32, also switches on the low
beams for approx. 40 seconds. In addition, the
door handle and interior lamps are switched on
for approx. 10 seconds.
Daytime running lamps*
The daytime running lamps light up in posi-
tion0, 1 or3. The light output is lower than with
the low-beam headlamps.
If the light switch remains in position1, then the
parking lamps are lit after the ignition is
switched off.
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables dynamic illumina-
tion of the road surface. Depending on the
steering angle and other parameters, the light

button.
The button for the interior lamps in the rear pas-
senger area only switches these lamps on and
off.
Reading lamps
Reading lamps are provided in the front and
rear, adjacent to the interior lamps. They can be
switched on and off with the respective button
located next to the them.
To avoid discharging the battery, all of the
vehicle's interior lamps are automatically
extinguished approx. 15 minutes after the igni-
tion is switched off.<

Maximally cooled air is obtained as
quickly as possible at an outside
temperature of approx. 327/06
and with the engine running.
The automatic climate control
changes over to the lowest temperature and
switches into the recirculated-air mode. The

wish to take advantage of the condensation
sensor.
Defrosting windows and removing
condensation

Residual heat
The system uses the warmth
stored in the engine to heat the
interior when the ignition is off, e.g.
while the vehicle is stopped at a
school to pick up a child.
The function can be switched on when the fol-
lowing conditions are met:
>up to 15 minutes after switching off the
engine
>with the engine at operating temperature
>with sufficient battery voltage
>at an outside temperature below 777/

Ventilation in rear
Use the lever1 to vary the airflow direction.
For additional information on rear ventilation
options, refer to page107.
Parked car ventilation
The parked car ventilation blows air into the
passenger compartment to reduce interior tem-
peratures.
You can set two different times for the system
to start. The system is operated via iDrive.
It remains switched on for 30 minutes.
Since the system uses a substantial amount of
electrical current, you should refrain from acti-
vating it twice in succession without allowing
the battery to be recharged in normal operation
between uses.
With a preselected switch-on time, the parked
car ventilation is switched on at an outside tem-
perature of 597/156 or greater. When oper-
ated manually, it is ready for use at any outside
temperature, but not during driving.
The air enters the passenger compartment
through the air vents for the upper body in the
dashboard, which can be adjusted for both
direction and airflow. These vents must be
open for the system to operate.

What to do if …
What to do if …
>a navigation DVD is inserted, but an instruc-
tion to insert the DVD appears on the Con-
trol Display?
The navigation DVD may not be the right
DVD for the navigation system. The DVD is
labeled accordingly.
>you request the current position of your
vehicle, but do not receive a precise dis-
play?
The system is unable to receive enough
GPS signals at your current position due to
obstructions, your position is not yet avail-
able on your navigation DVD, or the system
is in the process of calculating your posi-
tion. Please wait and then try again a little
later.
>the route guidance does not accept a desti-
nation?
The data of the destination is not stored on
the navigation DVD that is loaded. Select a
destination that is as close as possible to
the original.
>the route guidance does not accept a desti-
nation without the street?
On the navigation DVD, no downtown area
can be determined for the city or town
entered. Enter any street, or a destination
such as the railway station etc., then start
the route guidance.
>you want to enter a destination for the route
guidance, but it is not possible to select the
letters for your desired entry?
The data of the destination is not stored on
the navigation DVD that is loaded. In this
case, the system will not offer you any let-
ters to choose from. Select a destination
that is as close as possible to the original.>the system stops furnishing directions on
which way to turn as you approach intersec-
tions?
You are driving in an area that has not yet
been completely recorded on the naviga-
tion DVD. Instead of an arrow indicating a
turn, you will see an arrow which indicates
the general direction of your planned route.
Or you have left the recommended route
and the system requires a few seconds to
calculate a new recommended route.
>the navigation system does not react to
entries?
If the battery was disconnected, it then
takes up to 10 minutes before the system is
once again operational.
