Automatic climate control
*
Residual heating mode
The heat which is stored in
the engine is utilized for
heating the interior when the engine
has been switched off (while waiting at
a railroad crossing, for instance).
In ignition key position 1, you can alter
the settings of the automatic climate
control. In ignition key position 0, the
system automatically directs heated air
to the windshield, side windows and
footwells.
This function is available for oper-
ation when the outside tempera-
ture is below approx. 59 7 (15 6),
with the engine warm from recent oper-
ation and an adequate charge in the
battery. The LED on the button will light
up when all conditions have been
met.<
Draft-free ventilationYou can adjust the vent outlets for the
upper body area completely for your
personal comfort:
1 Rotary dials for infinitely-variable
opening and closing of the vent out-
lets
2 Selector levers for airflow direction
3 Rotary dial allows you to control the
temperature of the airflow as desired:
>Turn toward blue Ð colder
>Turn toward red Ð warmer.390de685
Rear passenger area ventilation1 Rotary dial for infinitely-variable
opening and closing of the vent out-
lets
2 Selector levers for airflow direction
3 The rotary dial operates in the same
way as the front dial to adjust the
temperature of the emerging air.390de686

Parked-car ventilation
*
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.
To operate, press the button briefly with
the ignition key in position 1 or 2.
Sun blinds for rear side windows
*
Use the strap to extract the blinds, then
hook them in the attachment provided.390us730
This system allows you to ventilate the
interior and lower its temperature using
the blower of the automatic climate
control.
The parked-car ventilation system is
operated via the Multi-Information Dis-
play (MID) Ð refer to page 92 Ð or the
onboard computer. Refer to the sepa-
rate 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.
The parked-car ventilation system is
available for timer-controlled operation
at outside temperatures above 60 7
(16 6) as well as for manual operation
at any temperature, provided that the
vehicle is stationary.
The air emerges via the vent outlets for
the upper body. Therefore, the vent
outlets must be open for the system to
operate.

Towing 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-startingIt 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 164.
Never attempt to use your vehicle to
push another vehicle, since damage to
the energy-absorbing bumpers could
result.
Towing a vehicle with automatic
transmission1. 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
signal indicators, horn and wind-
shield wipers remain operative, and
to prevent the steering lock from
engaging
5. Switch on the hazard warning
flashers (observe official regulations).
Find some means of identifying the
vehicle 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.<
