Rear passenger area ventilationRotary dial 1 opens the outlets in an in-
finitely-variable range. You can vary the
temperature of the air as it flows out us-
ing rotary dial 3 in the same manner as
for the front rotary dial.
You can change the direction of the air-
flow with levers 2.390de354
Microfilter, activated-charcoal
filterThe microfilter removes dust and pollen
from the incoming air. The activated-
charcoal filter provides additional
protection by filtering gaseous pollut-
ants from the outside air. Your BMW
center replaces this combined filter as a
standard part of your scheduled main-
tenance. A substantial reduction in air-
flow indicates that the filter must be
replaced before scheduled mainte-
nance.
The seat cushion and backrest can
be heated with the ignition key in posi-
tion 2.
You can call up different heating modes
by repeatedly pressing the keys.
The highest heating mode is on when
the three indicator lamps are lit; one
lamp is lit for lowest heating. Tempera-
ture regulation in each mode is with a
thermostat.
You can also switch the higher heating
modes off directly:
Press the key and hold it slightly longer.

Steering wheel heating

Roller sun blind

Independent ventilation
*
To activate and cancel the steering
wheel heater, press the button (arrow)
with the ignition key in position 2.
The lamp within the button lights up
when the steering wheel heater is in
operation.
If you have a multifunction steering
wheel without steering wheel heating,
the button for the recirculated-air mode
is in this location (refer to page 25).390de656
To operate, press the key briefly with
the ignition key in position 1 or 2.Roller sun blinds for rear side
windows
*
Use the strap to extract the blinds, then
hook them in the attachment provided.390us718
This system allows you to ventilate the
interior and lower its temperature, using
the blower of the automatic climate
control.
The independent ventilation system is
operated via the Multi-Information Dis-
play (MID) – refer to page 94 – or the
onboard monitor. Refer to the separate
Owner's Manual.
You can set two different times for the
system to start; it will remain active for
30 minutes. You can also turn it on and
off directly. Since the system uses a
substantial amount of electrical current,
you should not activate it twice in suc-
cession without allowing the battery to
be recharged in normal operation
between use.
When a preselected activation time is
set, the independent ventilation system
is operational at outside temperatures
above 607 (166), or by direct switch
activation. It cannot be switched on
when the vehicle is moving.
The air emerges via the vent outlets for
the upper body. Therefore, the vents
must be open for the system to oper-
ate.

Glove compartment Storage facilities

To open

Pull the handle and the lamp comes on.

To close

Fold the cover up.

To lock

Use one of the master keys to lock the

let parking (refer to page 36), access to
the glove compartment is not possi-
ble.

glove compartment.
Features integral overload-protection,
so it can be left in its holder continu-
ously.
Be sure that the flashlight is
switched off when it is inserted
into its holder. Failure to comply with
this precaution could lead to over-
charging and damage.

128nThrough-loading system*
The backrest of the rear seat is divided
into two portions, one-third and two-
thirds of the seat respectively. For stor-
ing longer objects, you can fold down
either side individually.
To open:
Reach into the recess and pull forward
(arrow 1).
When you close the backrest, be sure
that the catch engages securely. The
red slide (arrow 2) must go underneath.

The central belt has an additional small
buckle.
>If you connect the two belt sections,
you can use the central belt as any
normal 3-point belt.
> It is easier to fold the rear seat back-
rest up and down if you unbuckle the
belt (arrow).
394de303
With a master key, you can lock each
backrest in the rear seat.
This also prevents access to the lug-
gage compartment from the interior of
the vehicle when you turn over the door
and ignition key 3 to someone else
(refer to page 36), for valet parking for
instance.

202nTowing the vehicle
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it is no longer
possible to control vehicle response. <
Tow-starting
It is not possible to start the engine of
vehicles equipped with an automatic
transmission by towing or pushing.
For instructions on jump starting, refer
to page 200.
Never attempt to use your vehicle to
push another vehicle, since damage to
the energy-absorbing bumpers could
result.
Towing a vehicle with automatic
transmission
1 Place the selector lever in position N.
2 Towing speed: Max. 45 mph (70 km/h).
3 Towing distance: Max. 95 miles (150 km).
4 Leave the ignition key in position 1 to ensure that the brake lamps, turn sig-
nals, horn and windshield wipers re-
main operative, and to prevent the
steering lock detent from engaging.
5 Switch on the hazard warning flash- ers (observe country-specific regula-
tions).
Find some means of identifying the ve-
hicle in tow, for instance, place a sign
or warning triangle in the rear window.
Make sure that the ignition key
remains in position 1 even when
the electrical system has failed to pre-
vent the steering lock from engaging.
The steering and brakes are without
power assist when the engine is off.
This means that increased effort is
required for steering and braking. <
Towing with a commercial
tow truck
> Do not tow with sling-type equip-
ment.
> Use a wheel lift or flat bed carrier.
> Please comply with applicable towing
laws.
Never allow passengers to ride in
a towed vehicle for any reason. <

Deceleration sensors continuously
monitor the physical forces acting upon
the vehicle. If, as the result of a frontal
collision, vehicle deceleration is
reached at which the protection of the
safety belts alone is no longer ade-
quate, the gas generators of the driver-
side and passenger-side airbags are ig-
nited simultaneously. However, the
front airbag on the passenger-side is
only triggered if an additional sensor
has recognized that the passenger seat
is occupied.
Depending on which side the vehicle is
involved in a side collision, the head
protection and side airbags in the front
and rear
* are triggered if necessary.
390de319
The airbags located under the marked
covers inflate and unfold in a matter of
a few milliseconds. In this process they
tear through the rated breaking points
of the upholstered covers or press them
out.
Because the inflation process must be
virtually instantaneous, it is necessarily
accompanied by a certain amount of
ignition and inflation noise. The gas
which the system employs to inflate the
airbag is not dangerous. Smoke
appears as the gas dissipates.
The entire process is completed within
fractions of a second.
