Electronic vehicle immobilizer The key to securityYour BMW is equipped with a passive
anti-theft system. This electronic immo-
bilization system is designed to reduce
the susceptibility of your vehicle to theft
by making it impossible to start the en-
gine using any means other than the
special keys furnished with the vehicle.
Your BMW center can cancel the elec-
tronic system authorization for individ-
ual keys (in the event of loss, for in-
stance). A deactivated key can no
longer be used to start the engine.520de148
How the electronics workAt the heart of this system is an elec-
tronic chip that is integrated into the
key. The lock mechanism itself is actu-
ally a dual-function device, simulta-
neously serving as a communications
interface designed to allow the security
system to maintain a continuous stream
of variable, vehicle-specific signals with
the electronic circuitry in the key. The
system will release the ignition, electri-
cal steering lock, fuel injection and
starter for use only if it detects an
"authorized" key.
Forcing the key can damage the
integrated electronic circuitry. A
damaged key can no longer be used to
unlock the steering column and start
the engine.<

Central locking system Opening and closing Ð from outside The conceptThe central locking system is ready for
operation whenever the driver's door is
closed. The system engages and re-
leases the locks on the:
>Doors
>Luggage compartment lid
>Fuel filler door
>Glove compartment
>Storage shelf for the cellular phone.
The central locking system can be
operated:
>From outside via the driver's door
lock, or by using the remote control
>From inside by pressing a button.
If you initiate central locking from in-
side, neither the fuel filler door, glove
compartment, nor the storage shelf for
the cellular phone are locked (refer to
page 34).
If you do set it from outside, the anti-
theft alarm is automatically activated as
well. This prevents the door handles
from unlocking the doors. The alarm
system is also activated or deactivated.
If locked from inside, the central locking
system unlocks automatically in the
event of an accident. In addition, the
hazard warning flashers and interior
lamps come on.
Using the keySwing the cover panel for the door lock
upward. After either locking or unlock-
ing, return it to its original position until
it clicks back into its final position.
Turning the key in the driver's door
once will unlock the driver's door only;
turning the key a second time will un-
lock the passenger door, the luggage
compartment lid, fuel filler door, the
glove compartment, and the storage
shelf for the cellular phone.
If necessary, you can open the fuel filler
door by pressing the respective button
inside the vehicle; refer to page 23.
You can have various signals set
as an acknowledgment message
when locking.<520de100
Convenience operationYou can also operate the windows via
the door lock.
>To open: with the door closed, turn
the key to the "Unlock" position and
hold it
>To close: with the door closed, turn
the key to the "Lock" position and
hold it.
Watch during the closing process
to be sure that no one is inadvert-
ently injured. Releasing the key stops
the operation. Turn the key all the way to the extreme
left or right to unlock/lock the driver's
door.
Refer to page 141 for operating the
passenger-side door.

can activate the displays shown in the
illustration by pressing the button in the
instrument cluster (arrow).2 Trip odometerTo reset the trip odometer to zero,
press the button (arrow) with the igni-
tion key in position 1.520us004
Avoid engine speeds in the gauge's red
warning zone.
If the needle gets into this range, fuel
supply is interrupted to protect the en-
gine, resulting in a noticeable loss of
power.520de029
When you switch on the ignition, the
indicator lamp lights up briefly to
confirm that the system is operational.
Once the indicator lamp comes on and
stays on, there are approx. 2.6 gallons
(10 liters) of fuel left in the fuel tank.
For fuel tank capacity, refer to
page 157.
Certain operating conditions (such
as those encountered in mountainous
areas) may cause the needle to fluctu-
ate slightly.
Please refuel early, since driving
to the last drop of fuel can result
in damage to the engine or catalytic
converter.<520us005

Brakes:
Do not rest your foot on the brake
pedal while driving. Even light but con-
sistent pressure on the brake pedal
could lead to high temperatures, brake
wear, and possibly, to brake system
failure.
Aquaplaning:
Reduce speed while driving on wet or
slushy roads, otherwise, a wedge of
water can form between the tires and
the road surface. This phenomenon is
referred to as "aquaplaning" or "hydro-
planing." It is characterized by a partial
or complete loss of contact between
the tires and the road surface. The ulti-
mate results are loss of steering and
braking control.
Driving through water:
When there is water on the roads, do
not drive in it if it is deeper than 1 ft
(30 cm), and even then, only at walking
speed, otherwise the vehicle can sus-
tain damage to the engine, the electri-
cal systems and the transmission.<
The catalytic converter reduces harmful
exhaust emissions, and is designed for
use with unleaded fuel only. Even
minute quantities of lead would be
enough to permanently damage both
the catalytic converter and the system
oxygen sensor.To ensure efficient, trouble-free engine
operation and to avoid potential damage:>Be sure to comply with the scheduled
maintenance requirements
>Fill the fuel tank well before it is empty
>Tow-start only when the engine is
cold. If you attempt to tow-start with
a warm engine, unburned residual
fuel in the catalytic converter could
ignite and cause damage. It is better
to start the vehicle with an outside
starting aid
>Avoid other situations where the fuel
is either not burned or burns incom-
pletely, such as engaging the starter
frequently or for extended periods, or
repeated start attempts in which the
engine does not start (stopping and
restarting an engine which is running
properly does not present a prob-
lem). Never allow the engine to run
with any of the spark plug cables dis-
connected.Be sure to comply with the in-
structions above to prevent un-
burned fuel from reaching the catalytic
converter. Otherwise, there is the dan-
ger of overheating and damage to the
catalytic converter.
Extreme temperatures are present with
the catalytic converter both on this and
every catalytic converter-equipped ve-
hicle. Heat shields are installed adja-
cent to some sections of the exhaust
system. Never remove these shields;
do not apply undercoating to their sur-
faces. When driving, standing at idle,
and parking the vehicle, take care to
avoid contact between the exhaust sys-
tem and flammable materials (grass,
hay, leaves etc.). Such contact could
start a fire, resulting in serious personal
injury and property damage.<

Winter tires Snow chains
*
Choosing the right tireFor winter road driving, BMW recom-
mends winter tires (M+S radial belt
tires). Although all-season M+S tires
provide better winter traction than stan-
dard summer tires with H, V, W and ZR
speed ratings, they generally fail to pro-
vide the same levels of performance as
standard snow tires in winter driving.
In the interests of safe tracking and
steering response, install radial tires
made by the same manufacturer and
with the same tread configuration on all
four wheels if you elect to mount winter
tires.
Mount only winter tires that have been
approved by BMW. Any BMW center
will be glad to provide you with informa-
tion on the best winter tires for your
particular driving conditions.
Use only winter tires with emer-
gency driving characteristics as
there is no spare tire available if you get
a flat.
For further information, refer to
page 135.<
Do not exceed specified
maximum speeds
Never exceed the maximum speed
for which winter tires are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Your BMW center
will be glad to assist you with both their
expertise and the proper equipment for
your vehicle.<
Tire condition, tire pressureOnce the tread depth on winter tires is
less than 0.16 in (4 mm), they are no
longer suitable for winter road driving,
and in the interest of safety should be
replaced.
Comply with the specified tire inflation
pressures Ð and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.StorageAlways store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against con-
tact with oil, grease and fuel.
The use of narrow-link BMW snow
chains is permissible in pairs only on
the rear wheels with winter tires with
tire size 245/45 R 18 96 H. Comply with
all manufacturer's safety precautions
when mounting the chains.
Do not activate the RDW system
while using snow chains.
Malfunction warnings and undetected
losses in pressure are possible when
driving with snow chains.
For further information, refer to
page 65.<

Engine oilChecking the oil level 1 Park the vehicle on a level surface
2 Let the warmed-up engine idle for
about 15 seconds, then turn it off
3 Pull the dipstick out after about
1 minute and wipe it off with a clean
lint-free cloth, tissue, or similar
material
4 Carefully push the dipstick all the way
into the guide tube and pull it out
again
5 The oil level should be between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.520de089
The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts (1 liter). Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.520de091
Adding engine oil Wait until the level has dropped to just
above the lower mark before adding oil.
However, never let the oil drop below
the lower mark.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This also applies to the
manual transmission, differential and
the power steering system.<520de090

Caring for your vehicleCaring for the vehicle finish Regular washing is a preventive mea-
sure against long-term effects from
substances that are harmful to the vehi-
cle's finish, especially if you drive your
vehicle in areas with high levels of air
pollution or natural contaminants (tree
resins, pollen).
Nevertheless, you should immediately
remove especially aggressive sub-
stances. Failure to do so can lead to
changes in the paint's chemical struc-
ture or to discoloration. Gasoline spilled
during refueling, oil, grease, brake fluid
and bird droppings should always be
cleaned up immediately.
Any contamination remaining on the
surface of the vehicle will be especially
conspicuous after washing. Use clean-
ing fluid or alcohol and a clean cloth
or cotton pad to remove. Remove tar
spots with tar remover. After cleaning,
the affected areas should be waxed to
ensure continued protection.
Use the cleaning and car-care
products available at your BMW
center.<
Waxing your vehicle Protect the finish using carnauba or
synthetic-based waxes only.
The best way to determine when the
finish needs to be waxed is by noting
when water stops beading on the
surface.
You can use a glass cleaner to remove
any wax or silicone that may have been
left on the windows during waxing.
Use the cleaning and car-care
products available at your BMW
center.<
Repairing the paint You can touch up small areas of paint
damage with a BMW spray paint or a
BMW touchup stick.
The color code of your vehicle is pro-
vided on a tag located near the vehicle
data plate and on the first page of the
Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).
More extensive paint damage should
be repaired professionally in accor-
dance with the manufacturer's instruc-
tions. Your BMW center uses original
BMW finish materials in accordance
with approved repair procedures.

Caring for your vehicleWindow careYou can use window and glass cleaner
to clean inside window surfaces and
mirrors without smearing and streaking.
Never use polishing pastes or abrasive
(quartz) cleansers on mirror lenses.
Clean the wiper blades with soapy
water. The wiper blades should be re-
placed twice a year Ð before and after
the cold season.
Use only wiper blades approved
by BMW.<
Caring for other vehicle
components and materials Light-alloy wheels should be treated
with alloy wheel cleaner, especially dur-
ing the winter months. However, do not
use aggressive products containing
acids, strong alkalis or abrasives. Do
not use steam cleaners operating at
temperatures above 140 7 (60 6).
Follow the manufacturer's instructions.
Carefully clean chrome parts such as
lamp socket assemblies, door handles
and similar items with an ample amount
of clean water Ð and shampoo, too, if
necessary Ð especially if there is an ac-
cumulation of road salt. Use a chrome
polish for an additional treatment.
Use water to clean plastic components,
headliners, lamp lenses, and surfaces
sprayed dull black Ð adding vinyl sham-
poo, if necessary. Do not allow mois-
ture to soak through the seats or head-
liner. Never use solvents such as lac-
quer thinner, heavy-duty grease re-
mover, fuels, or similar substances.
Use a soft, clean cloth to wipe off the
lamp covers, using methylated spirits
with distilled water as a cleaning sol-
vent, if necessary, at a mixing ratio
of 1:1.Rubber components should be cleaned
with water only; a rubber treatment or
silicone spray may also be applied.
The safety belts should be cleaned with
a mild soap and water solution without
being removed from the vehicle. Never
attempt chemical or dry cleaning, as
damage to the belt fabric could result.
After cleaning, never allow the inertia
reel to retract the belts until they are
completely dry. Dirty safety belts pre-
vent the inertia reel mechanism from
retracting the strap properly, thus
constituting a safety hazard.
Heavily soiled floor carpets and mats
*
can be cleaned with an interior cleaner.
The floor mats can be removed from
the vehicle for cleaning.
Clean the aluminum surfaces with water
and, if necessary, with a mild soap.
Never use solvents such as lacquer
thinner, heavy-duty grease remover,
fuels, or similar substances.
Use only a wet cloth to clean the painted
inner parts. Dry them afterwards with a
soft cloth.
Use the cleaning and car-care
products available at your BMW
center.<
