Sequential M gearbox* SMG II
Indicator/Headlamp ßasher
SMG II must "become familiar" with the
changed condition.
Reinitialize the system afterwards:
1. Move the selector lever into
position 0 on a straight stretch of
road at a speed of over 20 mph
(30 km/h)
2. Pull both shift paddles for approx.
2 seconds.
If you do not carry out the initialization,
the system automatically "learns" the
changed condition gradually during
driving. This can become apparent due
to brief opening and closing of the
clutch. 1 High beams (blue indicator lamp)
2 Headlamp flasher (blue indicator
lamp)
3 Turn signal indicator (green indicator
lamp accompanied by periodic
clicking sound from the relay)
To signal brieflyPress the lever up to but not beyond
the resistance point. It then returns to
the center position when released.
If the indicator lamp of the turn
signal indicators and the clicking
from the relay are both faster than
normal, one of the turn signal indicators
has failed.<

Cruise control To deceleratePress button (Ð) briefly:
When cruise control is active, every tap
of the button reduces the speed by
approx. 0.6 mph (1 km/h).
Press and hold button (Ð):
With the cruise control active, the
system automatically reduces the
throttle opening to slow the vehicle.
When you release the button, the
system maintains and stores the
current speed.
To interrupt the cruise controlWhen the system is activated, press the
button. The indicator lamp stays on.
You can use the cruise control again
whenever you want by calling up the
speed that was stored last.
In addition, cruise control is interrupted
automatically:
>When the brakes are applied
>When pressing down the clutch pedal
>If you exceed or fall below the
programmed speed for an extended
period (by depressing the acceler-
ator, for example)
>When shifting in the sequential mode,
refer to sequential M gearbox
*
SMG II on page 59.
To recall the stored speedPress button:
The vehicle accelerates to and main-
tains the last speed stored.

Tire replacement Wheel and tire combinationsTire ageBMW recommends the replacement of
all tires after 6 years at the latest, even
if a tire life of 10 years is possible.
The date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 4 101 means that the tire was
produced in the 41st week of the year
2001. Following wheel/tire changesFollowing wheel and/or tire replace-
ment you will need to reinitialize both
the Flat Tire Monitor and the sequential
M gearbox
* SMG II, refer to pages 65,
78.
The right choice
Use only wheels and tires
approved by BMW for the corre-
sponding vehicle model, as otherwise
the tires may make contact with the
body as the result of tolerances despite
the same nominal size being used,
resulting in serious accidents. If non-
approved wheels and tires are used,
BMW cannot evaluate their suitability,
and therefore cannot be held liable for
driving safety.<
BMW tests certain tire brands for each
tire size, classifies them as road-safe
and approves them. Consult your BMW
center for more information. Observe
any country-specific regulations, e.g.
on making a corresponding entry in the
vehicle documents.
The correct wheel and tire combi-
nation affects different systems
such as ABS, DSC, Flat Tire Monitor.
The function of these systems is
impaired if improper wheel and tire
combinations are used.
For this reason, use only tires of the
same brand and tread pattern on the
vehicle and, for example, restore the
approved wheel and tire combination
following a flat tire as soon as possible.<
The use of rims and lug bolts that
do not meet the specifications of
the original factory-installed equipment
will affect the safe operation of your
vehicle and may cause an accident and
personal injury.
Never mix tires of different design, such
as steel-belted radials with radial bias-
belted or bias-ply tires, etc. Mixing tire
types will adversely affect roadholding
and can lead to loss of vehicle
control.<
Storage Store tires in a cool, dry place,
protecting them against light whenever
possible. Protect the tires against
contact with oil, grease and fuel.

Special characteristics of winter tires Snow chainsChoosing the right tireBMW recommends winter tires (M+S
radial tires) for operation under adverse
winter driving conditions. So-called all-
season tires with the M+S identification
mark do indeed possess better winter
traction than summer tires that have the
H, V, W, Y and ZR speed ratings, they
generally fail to provide the same levels
of performance as snow tires.
In the interest of safe tracking and
steering response, install winter tires
made by the same manufacturer having
the same tread configuration on all four
wheels. 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. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire pressureOnce winter tires wear to a tread depth
of less than 0.16 in (4 mm), their perfor-
mance under winter driving conditions
deteriorates noticeably. Worn tires
should therefore be replaced for safety
considerations.
Inflate tires to specified pressure and
have the wheels balanced every time
the tires or wheels have been replaced.Use narrow-link BMW snow chains
* on
winter tires in pairs only and only on the
rear wheels. Comply with all manufac-
turer's safety precautions when
mounting the chains. Do not exceed a
maximum speed of 30 mph (50 km/h)
with snow chains.
After mounting or removing snow
chains, always reinitialize the sequential
M gearbox
* SMG II, refer to page 65.
It is not possible to mount snow
chains on tires with 18- and
19-inch wheels.
Deactivate the Flat Tire Monitor when
using snow chains. Malfunction warn-
ings and undetected losses in pressure
are a possibility when driving with snow
chains.
For additional information, refer to
page 77.<

Towing the vehicleTowing a vehicle1. Shift lever in Neutral
2. Towing speed:
Max. 45 mph (70 km/h)
3. Towing distance:
Max. 95 miles (150 km)
4. Leave the ignition key at position 1 to
ensure that the brake lamps, turn
signal indicators, horn and wind-
shield wipers remain operative, and
to prevent the steering lock detent
from engaging
5. Switch on the hazard-warning
system (observe applicable legal
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
prevent 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.c
Vehicles with sequential M gearbox
*
SMG II:
To push or tow, engage selector lever
in position 0.
Never work on the vehicle with a
driving position engaged.c
Towing with a commercial tow
truck>Do not tow with sling-type equipment
>Use wheel lift or flatbed equipment
>Please comply with applicable state
towing laws.
Never allow passengers to ride in
a towed vehicle for any reason.
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.c
