Vehicle Memory, Key MemoryHow the system functionsNo doubt you have reflected at one
time or another on how great it would
be if you could permanently configure
your vehicle's various features and
adjustments to mirror your own individ-
ual preferences. In engineering your
vehicle, BMW has provided for a num-
ber of options for personal adjustment
that can be programmed into your vehi-
cle at your BMW center.
The available configuration data fall into
two categories, according to whether
their primary orientation is the vehicle –
Vehicle Memory – or the individual –
Key Memory. Provided that each per-
son has a separate remote-control key,
you can have your BMW center enter
basic adjustment data for up to four
individuals in the system.
The system then relies on a bilateral
data exchange to identify the individual
user and executes the selected settings
whenever the remote control unit is
used to disengage the door locks.
Distinguishing between keysColor-coded decals have been pro-
vided to help you distinguish individual
keys with different settings.What the system can doYou can learn about the entire array of
features this system offers at your BMW
center.
You will see this symbol through-
out the Owner's Manual. It is to
remind you at appropriate places of the
settings that are available to you.<

RReverseSelect only when the vehicle is station-
ary.NNeutralAlways engage before starting the
engine, refer to Starting the engine on
page 66.Sequential modeEach time the engine is started, the
sequential mode is activated as soon as
you move the selector lever into the for-
ward driving position while the brake is
depressed.
The gears are shifted via the shift pad-
dles or the selector lever.
It is also possible to drive off in second
gear, e.g. on snow-covered roads.DDrive modeIn the drive mode all forward gears are
shifted automatically.
To switch from sequential to drive
mode: tap the selector lever to the right
toward D.
For rapid acceleration, e.g. during
passing, depress the accelerator pedal
completely: kickdown.To switch back to sequential mode: tap
the selector lever again to the right
toward D or change the current gear via
the shift paddles or the selector lever.
KickdownYou can achieve maximum acceleration
using kickdown.
Depress the accelerator pedal past the
increased resistance point at the full-
throttle position.
Shifting gearsWith selector lever:
>To upshift, tap the selector lever
toward +
>To downshift, tap the lever toward —.
With shift paddles on steering wheel:
>To upshift, pull one of the shift pad-
dles
>To downshift, push the paddle.
You accelerate from higher gears, e.g.
during passing, by manually downshift-
ing.
In the following situations, the SMG in
the sequential mode assists you:
>The transmission will only execute
upshifts and downshifts that will
result in an appropriate combination
of vehicle speed and engine rpm. For

ClockIf you wish to have a permanent time
display, you can make this adjustment
in the radio display, refer to the Owner's
Manual for Radio.
You can adjust the clock and the time
display in the car radio as follows.
Setting
Before the clock can be set, the
time must be showing in the
instrument cluster display.<
With the ignition key in position 1 or
higher
To set ahead: turn the right button to
the right.
To set back: turn the right button to the
left.
The adjustment speed will increase the
longer you continue to hold the right
button.
To change the display mode: press the
right button briefly.
Every time you press the button, the
clock display alternates between the
12-hour and 24-hour mode.
In ignition key position 0: the time is
displayed for a few seconds after you
press the left button, refer to Odometer
on page 80.

Computer*Mode selectionWith the ignition key in position 1 or
higher, you can use the button in the
turn signal lever to request information
from the computer. Each time you
press the button briefly toward the
steering column, a new function is
called up in the display.
The displays appear in the following
order:
Time of day, outside temperature, aver-
age fuel consumption, cruising range,
average vehicle speed.
With the ignition key in position 1 or
higher, the last active setting is dis-
played.
Outside temperatureYou can change the units of measure
6/7 for the outside temperature dis-
play by pressing the right-hand reset
button in the instrument cluster while
the temperature display is active. The
units of measure 6/7 in the tempera-
ture display of the automatic climate
control change automatically, see
page 102.Ice warningIf the outside temperature drops to
about 37.57/+36, then the computer
will automatically switch to a display of
the outside temperature. In addition, a
signal sounds as a warning and the dis-
play flashes for a brief period.
After giving an ice warning, the
display returns to the previous
setting.<
The ice warning does not alter the
fact that surface ice can form at
temperatures above 37.57/+36, on
bridges or shaded road surfaces, for
instance.<

92
Flat Tire Monitor*The conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires. The system alerts you whenever
the inflation pressure of a tire falls sig-
nificantly below the pressure of another
tire.
The system actually detects pressure
loss by monitoring differences in the
relative speeds of the four wheels. It
interprets variations outside specified
limits as severe pressure loss, and then
responds by generating a warning.Functional requirementsIn order for the Flat Tire Monitor to learn
the correct tire inflation pressure,
please do the following:
1. Check the tire inflation pressures in
all tires
2. Compare them with the tire inflation
pressure table on page 26 and cor-
rect them, if necessary
3. Initialize the system.
System limitations
The Flat Tire Monitor cannot pro-
vide you with advance warning of
sudden and severe tire damage caused
by external factors and does not detect
the balanced and very gradual pressure
loss that takes place in all four tires
over an extended period of time.<
On the other hand, the following situa-
tions can lead to a delayed detection of
pressure loss and even to the system
not functioning:
>Driving on snow-covered or slippery
roads
>Performance-oriented driving: slip at
the drive wheels, high levels of lateral
acceleration
>When driving with snow chains, false
warnings and undetected pressure
losses may occur
>When driving with a space-saver
spare tire, the Flat Tire Monitor can-
not function.
Initializing the system
Each time you correct the pres-
sure in a tire, or change a wheel or
tire, reinitialize the system immediately
afterwards. This requires a bit of driv-
ing.<
1. Before driving off, start the engine
but do not start driving
2. Press the button as long as you need
to until the yellow indicator lamp in
the instrument cluster lights up for a
few seconds
3. Drive off.
It takes a few minutes before the Flat
Tire Monitor can detect a flat tire and
issue a warning.

94Lamps
Parking lamps/Low beamsParking lamps
The front, rear and side vehicle
lighting is switched on. You can
use the parking lamps to signal
the position of the vehicle when it is
parked. For lighting on one side for
parking as an additional feature, refer to
page 95.
Low beams
When the ignition is switched off
while the low beams are on, the
headlamps go out and only the
parking lamps remain on.
Follow me home lampsWhen you activate the headlamp
flasher after parking the vehicle with the
lamps turned off, the low-beam head-
lamps will come on for a short time.
You can also have this function
deactivated.<LIGHTS ON warningWhen you open the driver's door after
having turned the ignition key to posi-
tion 0, you will hear an acoustic signal
for a few seconds to remind you that
the lamps have not been switched off.Daytime driving lamps*If you desire, the light switch can be left
in the second position: when the igni-
tion is switched off, the external lighting
is also switched off.
You can have the activation set-
tings for the daytime driving lamps
programmed on your vehicle.<
Automatic headlamp control*
When the switch is set to this
position, the system automati-
cally activates and cancels the
low beams in response to changes in
ambient light – in tunnels, at dusk, etc. –
and in the event of rain and snow.
The vehicle's external lights
remain on constantly when you
switch on the front fog lamps after the
headlamps have come on automati-
cally.<
Automatic headlamp control can-
not serve as a substitute for the
driver's judgement in determining when
the vehicle lights should be switched
on. For example, the sensors are not
able to detect fog. To avoid safety risks,
you should respond to these kinds of
low-visibility situations by switching the
headlamps on manually.<
You can have the sensitivity of
your vehicle's automatic head-
lamp control adjusted.<

125
Do not drive on a flat tire unless
your vehicle is equipped with Run
Flat tires. A flat tire greatly impairs
steering and braking response, and can
lead to complete loss of control over
the vehicle. Avoid overloading the vehi-
cle so that the permitted load on the
tires is not exceeded. Overloading can
lead to overheating and internal tire
damage.
The ultimate result can assume the
form of a sudden air loss.
Unusual vibrations encountered during
normal vehicle operation can indicate a
flat tire or some other vehicle malfunc-
tion. This type of problem can be
caused by contact with curbs, etc. This
is also true for abnormalities in the vehi-
cle's handling characteristics, such as a
pronounced tendency to pull to the left
or right. Should this occur, respond by
immediately reducing your speed. Pro-
ceed carefully to the nearest BMW cen-
ter or professional tire center, or have
the vehicle towed in to have it, its
wheels or its tires inspected.
Tire damage up to and including sud-
den and complete air loss can endan-
ger the lives of both the vehicle occu-
pants and other road users.<
Tire replacementTo maintain good handling and vehicle
response, use only tires of a single
tread configuration from a single manu-
facturer.
Comply with the specified tire inflation
pressures — and be sure to have the
wheel and tire assembly balanced
every time you change a tire or wheel.DOT quality gradesTread wear
Traction AA A B C
Temperature A B C
All passenger car tires must con-
form to Federal Safety Require-
ments in addition to these grades.<Tread wearThe tread wear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled condi-
tions on a specified government test
course.
For example, a tire graded 150 would
wear one and one-half – 1
1/2 – times as
well on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may
depart significantly from the norm due
to variations in driving habits, service
practices and differences in road char-
acteristics and climate.TractionThe traction grades, from highest to
lowest, are AA, A, B, and C.
Those grades represent the tire's ability
to stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction.
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests, and does
not include acceleration, cornering,
hydroplaning, or peak traction charac-
teristics.<TemperatureThe temperature grades are A – the
highest – B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.

the tire sidewall, refer to Changing a
wheel. In this case, use only Run Flat
winter tires, since no spare tire is pro-
vided in the event of a flat tire.Tire condition, tire pressureAt tread depths below approx. 3/16 in /
4 mm, winter tires display a perceptible
decrease in their ability to cope with
winter driving conditions, and should be
replaced in the interest of safety.
Comply with the specified tire inflation
pressures — and be sure to have the
wheel and tire assembly balanced
every time you change a tire or wheel.Snow chains*Only certain snow chains have been
tested by BMW and determined and
approved as roadworthy. Consult any
BMW center for details. BMW recom-
mends using only these approved fine-
link snow chains. Use them in pairs on
either summer or winter tires, but only
on both rear wheels.325xi, 330xi: only in an emergency – for
instance, with the vehicle stuck on one
side, or when obstructions make it
impossible to reach one tire – a chain
may also be mounted on just one tire
for the limited period needed to resolve
the problem.
Comply with all manufacturer's safety
precautions when mounting the chains.
Do not exceed a speed of 30 mph /
50 km/h when using snow chains.
You cannot mount snow chains on the
following tires:
225/50 R 16
225/45 R 17
225/40 R 18
245/40 R 17
255/35 R 18
Do not initialize the Flat Tire Moni-
tor after mounting snow chains to
the tires.
When driving with snow chains, it may
be useful to turn off the DSC for a short
time, refer to page 88 or 89.<Winter tires

Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the brake system's
safety and reliability, have the brake
fluid changed every two years by a
BMW center. Refer to the Service and
Warranty Information Booklet for US
models or the Warranty and Service
Guide Booklet for Canadian models.
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its closed original container and in
a location which is out of reach of chil-
dren.
Do not spill the brake fluid and do not
fill the brake fluid reservoir beyond the
MAX mark. The brake fluid could ignite
upon contact with hot engine parts and
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating
the disposal of brake fluid.<

136Maintenance
The BMW Maintenance SystemThe BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and operat-
ing safety – and as cost-effectively as
possible for you.
Please keep in mind that regular main-
tenance is not only necessary for the
safety of your vehicle, but also plays a
significant role in maintaining the resale
value of the vehicle.
Service interval displayWhile conventional systems rely on
milage alone to determine when service
is due, the BMW Maintenance System
reflects the actual conditions under
which the vehicle is operated: some
miles are more strenuous than others.
From a maintenance point of view,
62,000 miles/100,000 km accumulated
in short-distance urban driving are not
the equivalent of the same distance
covered at moderate cruising speeds in
long-distance highway travel.
The BMW Maintenance System
includes the Engine Oil Service and
Inspections I and II.
This service strategy accurately reflects
your own vehicle's specific needs by
defining maintenance intervals accord-
ing to individual operating conditions.
Minimal use drivers – those who drive
significantly fewer than
6,200 miles/10,000 km annually –
should have the engine oil changed at
least every 2 years since oil deterio-
rates over time, regardless of use.Service and Warranty Information
Booklet for US models/
Warranty and Service Guide
Booklet for Canadian modelsFor additional information on required
maintenance intervals and procedures,
please refer to the Service and War-
ranty Information Booklet for US mod-
els, or the Warranty and Service Guide
Booklet for Canadian models.
As a precaution against corrosion, if
your vehicle is exposed to potential
damage from unimproved road sur-
faces we suggest that you have the
body checked for damage from stone
chips and gravel at the same time.
