Fuel specifications Tire inflation pressure Use unleaded gasoline only.
Recommended fuel: premium with a
minimum octane rating of 91 AKI.
BMW engines are equipped with knock
sensors and will adapt automatically
to different octane ratings, provided
that the minimum octane requirement
(87 AKI) is met.
Fuels with higher octane ratings will
provide enhanced performance and
lower fuel consumption, while the use
of fuels with low octane ratings will have
the opposite effect.
Do not use leaded fuels. The use
of leaded fuels will cause perma-
nent damage to the system's oxygen
sensor and the catalytic converter.<
AKI = Anti Knock Index
You will find the inflation pressures on
the inside door pillar (visible with door
open).Check tire pressuresAll pressure specifications are stated
in psi (kilopascal) with cold tires (cold =
ambient temperature). Refer to the next
page as well.
For vehicles with Tire Pressure Control
(RDC)
*:
After correcting the tire inflation pres-
sure, reactivate the system. Refer to
page 89.
462de197
Check tire inflation pressures reg-
ularly – at least every two weeks
and before beginning a longer trip.
Otherwise, incorrect tire pressure can
lead to driving instability or to tire dam-
age and accidents.
Check the tire pressure in the space-
saver tire as well.<

Tire inflation pressureObserve tire approval
specificationsThe inflation pressures in the table ap-
ply to tires made by BMW-approved
manufacturers. Your BMW center is
familiar with these pressures. Higher
pressures may be specified for tires
made by other manufacturers. Ap-
proved tire sizes are listed on
page 128.
Your vehicle is equipped with tires that
meet US and European standards. We
recommend the exclusive use of
BMW-approved tires.BMW Tires

Tire Pressure Control (RDC)
*
The conceptRDC monitors the tire pressure at all
four wheels – even while you are driv-
ing. The system provides an alert when-
ever the inflation pressure drops signifi-
cantly below the specified pressure in
one or more tires.
In order for the system to "learn" cor-
rect tire inflation pressure, check the
pressure in all the tires, compare your
pressures with those in the tire inflation
tables (page 28), and make corrections
as necessary. Then activate the system.
This indicator lamp in the
instrument cluster informs you
whenever the tire pressure is
not normal.
Activate the system 1 Turn the ignition key to position 2
(do not start the engine)
2 Press the button long enough for
the indicator lamp in the instrument
cluster to light up yellow for a few
seconds
3 After you have driven a few minutes,
RDC imports the current tire inflation
pressures as the nominal values to be
monitored.
You will only have to repeat this proce-
dure following a correction of the tire
inflation pressure. Otherwise, the RDC
functions automatically when the igni-
tion key is in position 2, and thus oper-
ates whenever the vehicle is driven.46cus013
Loss of tire pressureIf the inflation pressure has dropped
significantly over a long period of time
(which is normal for any tire), the
indicator lamp will come on with a
yellow lamp.
This alerts you that you should have the
tires inflated to the specified pressures
as soon as possible.
If you are prompted to check the
tire pressure shortly after a cor-
rection has been made, this indicates
that the corrected values were not ac-
curate. Please check the inflation pres-
sure again and make corrections ac-
cording to the inflation pressure table.
Then activate the system once again.<

Flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with
a red lamp. In addition, an acoustic sig-
nal goes off.
If this occurs, reduce vehicle speed im-
mediately and stop the vehicle. Avoid
hard brake applications. Do not over-
steer. Replace the wheel and flat tire.
The space-saver spare tire is pro-
vided for temporary use only in the
case of a tire failure. It does not have
RDC electronics and is not monitored.<
RDC cannot inform you of sudden
and severe tire damage caused by
external influences.<
Have the tires changed by your
BMW center.
Your BMW center is familiar with, and
has the special tools necessary, for
working on the RDC.<
System interferenceThe RDC may encounter interference
from outside equipment or devices
which use the same radio frequency.
The indicator lamp will come on with a
yellow lamp during the malfunction.
The indicator lamp also comes on
>in the event of a system fault
>if a wheel is mounted without RDC
electronics
>or if additional wheels using RDC
electronics are transported.
Please contact your BMW center for
additional information.

Car care

112n
To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you comply
with the following recommendations.
Engine and differentialUp to 1,200 miles (2,000 km):
Drive at varying engine and road
speeds, but do not exceed 4,500 rpm
or 100 mph (160 km/h) during this time.
Obey your local and state maximum
speed limits.
Refrain from using full throttle and avoid
pressing the accelerator beyond the
"kickdown" point.
After you have driven 1,200 miles
(2,000 km), you can gradually increase
the engine and road speed.
You should also comply with these
break-in procedures if the engine or
differential is replaced at a later point.
TiresDue to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed.
Thus, drive with extra care during the
initial 200 miles (300 km).
Obey your local and state maximum
speed limits.
When the vehicle is operated on
wet or slushy roads, a wedge of
water may form between the tire and
the road surface. This phenomenon is
referred to as aquaplaning, or hydro-
planing, and can lead to partial or com-
plete loss of traction, vehicle control
and braking effectiveness. Reduce your
speed on wet roads. their optimum wear and surface-con-
tact patterns until you have driven
approx. 300 miles (500 km).
To break in the separate parking brake
drums, apply the parking brake lightly
when coasting to a standstill (at a traffic
signal, for instance), provided that traf-
fic conditions allow you to do so.
To avoid corrosion, repeat this proce-
dure from time to time.
The brake lamps do not come on
when the parking brake is applied.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the
vehicle with the engine shut off – when
towing, for example – substantially
higher levels of pedal force will be
required to brake the vehicle.<
Break-in procedures

113n
IndexDataTechnologyRepairsCar careControlsOverview
Brakes:
Do not drive with your foot resting
on the brake pedal. Even light but con-
sistent pedal pressure can lead to high
temperatures, brake wear, and possibly
to brake failure.
Aquaplaning:
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the
tires and the road surface. This phe-
nomenon is referred to as aquaplaning
or hydroplaning. It is characterized by a
partial or complete loss of contact be-
tween the tires and the road surface.
The ultimate results are loss of steering
and braking control.
Driving through water:
Do not drive through water over the
road if it is deeper than 1 ft (30 cm), and
then only at walking speed, otherwise
the engine, electrical system and trans-
mission could be damaged.
Clothes hooks (when hardtop
* is
mounted):
When suspending clothing from the
hooks, ensure that they will not obstruct
the driver's vision. Do not hang heavy
objects on the hooks. If you do, they
could cause personal injury during
braking or evasive maneuvers.<
The catalytic converter reduces harmful
exhaust emissions. It 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 jump-start the vehicle with outside
assistance
>Avoid other situations in which the
fuel is 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 problem).
Never allow the engine to run with
any of the spark plug cables
disconnected.Be sure to observe the instruc-
tions above to prevent unburned
fuel from reaching the catalytic con-
verter, otherwise, the catalytic con-
verter could overheat and be damaged.
High temperatures occur in every vehi-
cle equipped with a catalytic converter.
Heat shields are installed adjacent to
some sections of the exhaust system.
Never remove these shields; do not
apply undercoating to their surfaces.
When driving, standing at idle, and
parking the vehicle, take extra care to
avoid contact between the exhaust sys-
tem and flammable materials (grass,
hay, leaves, etc.). Such contact could
lead to a fire, resulting in serious per-
sonal injury and property damage.<

Winter operationWinter is often accompanied by rapid
changes in weather, requiring not only
a different driving style, but also certain
preparations to the vehicle itself to en-
sure that your vehicle operates safely
and trouble free throughout the winter
months.CoolantBe sure that the coolant mixture con-
tains the year-round ratio of 50:50
water and antifreeze/corrosion protec-
tion. This mixture provides protection
against freezing down to approx. –34 7
(–37 6). Replace the coolant every four
years.LocksBMW door lock deicer can be used to
free them if frozen. This deicer also
contains lubricant.
After its use, treatment with BMW lock
barrel grease is recommended.
Rubber seals and components To prevent the weather stripping from
freezing, apply a spray-on rubber treat-
ment or silicone spray to the door, hood
and luggage compartment lid seals.
A full range of car care products is
available from your BMW center. both summer and winter tires. Mount
them in pairs on the rear wheels only
and comply with the manufacturer's
safety precautions. Do not exceed a
maximum speed of 30 mph (50 km/h).
In this type of exceptional situation
where the snow chains are mounted,
deactivate the DSC. Refer to page 88.
Starting offWhen starting off from a full stop in
deep snow or when "rocking" the vehi-
cle to free it, it may be effective to
deactivate the DSC system for a short
period. Refer to page 88.Driving on low-traction road
surfacesUse smooth, gentle pressure to control
the accelerator pedal. Avoid excessive
engine speeds and shift to the next
higher gear at an early point. On down-
hill grades or slopes, shift down to the
next lower gear at an early point. Main-
tain an adequate distance between
yourself and the vehicle ahead.

Winter operationBrakesWinter road conditions substantially
reduce the amount of traction available
between the tires and the road surface.
Keep this in mind, because the braking
distance increases substantially.
ABS is intended to prevent the wheels
from locking during brake applications,
thus helping to maintain vehicle stability
and steering response.
If the ABS does not respond in a critical
braking situation and the wheels lock,
reduce the pressure on the brake pedal
until the wheels just start to roll again
while still maintaining enough force to
continue braking. Then increase the
pressure, reduce the pressure when the
wheels lock, reapply pressure, etc.
This staggered braking procedure will
reduce stopping distances while help-
ing you maintain steering control.
You can then attempt to steer around
hazards after you have reduced pres-
sure on the brake pedal.Do not shift down on slick road
surfaces. Doing so could cause
the rear wheels to lose traction and
skid, which could result in the loss of
vehicle control.<
Depress the clutch during hard
braking on road surfaces that pro-
vide only poor or uneven traction.<
Skid control Depress the clutch and release the ac-
celerator pedal, or place the selector
lever of the automatic transmission into
the "Neutral" position. Countersteer
carefully and attempt to regain control
of the vehicle.
ParkingEngage first or reverse gear. If your
vehicle is equipped with an automatic
transmission, place the selector lever in
Park. On vehicles with manual trans-
mission, also apply the parking brake
when parking on inclined surfaces. In
order to prevent the parking brake pads
from locking due to frost or corrosion,
dry them by gently applying the parking
brake as the vehicle is coming to a
stop. Make sure that following traffic
is not endangered.
The brake lamps do not come
on when the parking brake
is applied.<
