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 approximately 59 7
(15 6), with the engine warm from
recent operation 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 air outlets for the
upper body area completely for your
personal comfort:
1 Rotary dials for infinitely-variable
opening and closing of the vent
outlets
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
outlets
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
airflow 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
Display (MID) Ð refer to page 90 Ð or
the onboard computer. 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
succession 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
vents must be open for the system to
operate.

Lamps and bulbsThe lamps and bulbs are essential
factors contributing to the safety of your
vehicle. For this reason, you should
follow the instructions below carefully
when replacing a bulb. If you are not
familiar with any of the procedures,
consult your BMW center.
Do not touch the glass portion of a
new bulb with your bare hands
since even small amounts of impurities
burn into the surface and reduce the
service life of the bulb. Use a clean
cloth, paper napkin, or a similar mate-
rial, or hold the bulb by its metallic
base.<
A replacement bulb set is available from
your BMW center.
Whenever working on the elec-
trical system, switch off the elec-
trical accessory you are working on or
disconnect the cable from the negative
terminal of the battery. Failure to do this
could result in short circuits.
To prevent injuries and damage,
comply with any instructions provided
by the bulb manufacturer.<

Failure to observe these precautions
can result in physical injury if the bulb
breaks.< 390de767
1. Turn the bulb holder to the left
(arrow) and remove
2. Remove and replace the bulb.
When cleaning the headlamps,
please observe the following:
>Do not wipe dry (scratches). Never
use abrasives or strong solvents to
clean the covers
>Remove dirt and contamination (such
as insects) by soaking with BMW Car
Shampoo and then rinsing with plenty
of water
>Always use a deicer spray to remove
accumulated ice and snow Ð never
use a scraper.<

Battery Fuses
Battery posts, terminals and other
components contain lead and lead
compounds. Wash hands after
handling.<
Battery careThe battery is maintenance-free, that is,
the original electrolyte will normally last
for the service life of the battery under
moderate climatic conditions.
For all questions that regard the
battery, please consult your BMW
center. The battery is completely main-
tenance-free; the following section is
provided for your information only.<
Do not disconnect the battery
when the engine is running, as the
ensuing voltage surge would damage
the vehicle's onboard electronics.<
Charging the batteryWhen charging the battery in the
vehicle, leave the engine off at all times.
Connect the charge cables to the termi-
nals in the engine compartment (for
terminal locations, refer to "Jump-
starting" on page 162.
Return used batteries to a recy-
cling point or your BMW center.
Maintain the battery in an upright posi-
tion for transport and storage. Secure
the battery against tilting during trans-
port.<

Do not use spray starter fluids to start
the engine.
When your battery is discharged you
can used two jumper cables to start
your car with power from the battery in
a second vehicle. You can also use the
same method to help start another
vehicle. Always use jumper cables with
fully insulated handles on the terminal
clamps.
Do not touch high-voltage wiring
and cables on a running engine.
Contact with components carrying high
voltage can be harmful or fatal. Care-
fully observe the following instructions
to avoid personal injury and/or damage
to one or both vehicles.<
1. Ensure that the battery in the
support vehicle is also rated at
12 volts. This information is
provided on the top of the battery
casing
2. Do not disconnect your battery from
your vehicle's electrical system.
Switch off all electrical accessories
in both vehicles
3. Make absolutely certain that there
is no contact between the body-
work of the two vehicles Ð short
circuit hazard
4. Start the engine on the support
vehicle and allow it to run
5. Use one jumper cable (+) to
connect the positive terminal of the
battery in the support vehicle with
the auxiliary positive terminal
provided in the engine compart-
ment of your BMW specifically for
jump-starting. The cover on this
auxiliary terminal is identified by a
"+" symbol, refer to the illustration.

6. Next, connect one end of the other
jumper cable (Ð) to either the
support vehicle's negative battery
terminal or a suitable ground on its
engine or bodywork. Connect the
other end to the negative battery
terminal or a suitable ground on the
vehicle being started. There is a
special nut on the strut dome of
your BMW; refer to the arrow in the
illustration
Always adhere to this sequence
when connecting jumper cables;
failure to observe this procedure can
lead to sparks at the battery terminals
and pose an injury hazard.< 390de146

OverviewControlsMaintenanceRepairsDataIndex
Jump-starting Towing the vehicle7. Start the support vehicle's engine
and let it run at an increased idling
speed for a few minutes. Start the
engine on the vehicle needing the
jump-start, and allow it to run as
usual. If the first start attempt is not
successful, wait a few minutes
before another attempt in order to
allow the discharged battery to
recharge
8. Before disconnecting the jumper
cables let the engines run for a few
minutes
9. Then disconnect the jumper cables
in reverse sequence.
Depending on the cause of the fault,
have the battery recharged by your
BMW center.
Tow fittingThe screw-in tow fitting is stored in the
onboard tool kit; be sure that it remains
in the vehicle at all times. This fitting is
designed for installation in the tow
sockets located at the front and rear of
the vehicle, and is intended for towing
on paved road surfaces only.
It should not be used to pull a vehicle
out of deep snow, mud, sand, etc.
Always observe all applicable towing
laws and regulations.Access to tow socketsFront:
Apply pressure to the arrow symbol on
the cover panel to remove.390de087
Rear:
Apply pressure to the arrow symbol on
the cover panel to remove.
Screw the tow fitting in until it
bottoms firmly. Failure to screw
the fitting all the way in can cause
thread damage.
Never attach tie-down hooks, chains,
straps, or tow hooks to tie rods, control
arms, or any other part of the vehicle
suspension, as severe damage to these
components will occur, leading to
possible accidents.<
Use only a nylon towing strap to tow
the vehicle, since the inherent resil-
ience of this material helps protect both
vehicles from sudden jerking move-
ments.394de088
