Fuel specifications Tire inflation pressure The engine uses lead-free gasoline
only.
Required fuel:
>Premium Unleaded Gasoline,
min. 91 AKI.
AKI = Anti Knock Index
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.<
Proper inflation pressures are on a
sticker attached to the B-pillar and
visible with the driver's door open.Check tire pressuresOn the next page you will find all the tire
pressure and ambient air temperature
specifications stated in the units usually
used in your country (psi; kilopascal).
For vehicles with RDC (Tire Pressure
Control):
After correcting the tire inflation pres-
sure, reactivate the system. Refer to
page 85.462de197
Check tire inflation pressures,
including the space-saver spare
tire, or spare tire, regularly, at least
every two weeks and before beginning
any extended driving. Otherwise, incor-
rect tire pressure can lead to tire
damage and accidents.
Inflate the spare tire to the highest
inflation specified for your vehicle.<

Tire inflation pressure Comply with tire approval
specificationsThe inflation pressures in the table
apply to tires from BMW-approved
manufacturers. Your BMW center is
familiar with these manufacturers.
Higher pressures may be specified for
tires made by other manufacturers. You
will find a list of approved tires begin-
ning on page 127.
Your vehicle is equipped with tires that
meet US and European standards. We
recommend the exclusive use of BMW-
approved tires.BMW Tires
All pressure specifications in
the table are indicated in psi
(kilopascal) for cold tires
(cold = ambient temperature)
325CiAll summer tires 30 (210) 35 (240) 35 (240) 42 (290)
All winter tires 33 (230) 38 (260) 38 (260) 45 (310)
330Ci All summer and winter tires 33 (230) 38 (260) 38 (260) 45 (310)
All Space-saver spare tire 61 (420)
For all-season tires, use the same tire inflation pressure as for summer tires.
When using extra load tires (205/50 R 17), the inflation pressure increases
by 3 psi (20 kilopascal) for summer tires.
330Ci: when using 225/45 R 17 91 W tires, the air pressure decreases by
3 psi (20 kilopascal).

In the event of a flat tire
If there is a tire failure with loss of pres-
sure, the indicator lamp comes on with
a red lamp. In addition, an acoustic
signal is sounded.
If this occurs, reduce vehicle speed
immediately to stop the vehicle in a safe
location. Avoid hard brake applications.
Do not oversteer. Replace the wheel
and flat tire.
The space-saver spare tire is
provided for temporary use only in
the event of tire pressure loss. It does
not have RDC electronics and is not
monitored. A full-size spare tire that has
the same dimensions as the tires
already mounted on the vehicle is
equipped with the necessary RDC elec-
tronics, and will be also monitored once
the tires have been mounted and the
system activated.
<
RDC cannot alert you to severe
and sudden tire damage caused
by external factors.
<
Have the tires changed by your
BMW center.
Your BMW center has been trained to
work with the RDC system and is
equipped with the necessary special
tools.
<
System interference
Local devices using the same radio
frequency can interfere with the RDC.
The yellow indicator lamp will come on
during the malfunction.
The indicator lamp also comes on
>
in the event of a system fault.
>
if a wheel is mounted without the
appropriate electronics.
>
if, in addition to the spare tire, addi-
tional wheels with RDC electronics
are on board.
Please contact your BMW center for
additional information.

Information for your safetyThe factory-approved radial tires are
matched to the vehicle and have been
selected to provide optimum safety and
driving comfort on your vehicle.
It is not merely the tire's service life, but
also driving comfort and Ð above all else
Ð driving safety that depend on the con-
dition of the tires and the maintenance
of the specified tire pressure.
Incorrect inflation pressure is a frequent
cause of tire damage. It also signifi-
cantly influences the roadholding ability
of your BMW.
Be sure to check the tire inflation
pressure Ð including the space-
saver spare tire or the spare tire Ð on a
regular basis, at least twice a month
and before doing any extended driving.
Refer to page 27. If this is not done, in-
correct tire pressures can cause driving
instability and tire damage, ultimately
resulting in an accident.<
Tire tread Ð tire damageInspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread depth.
Tread depth should not be allowed to
go below 0.12 in (3 mm), even though
the legally specified minimum tread
depth is only 0.063 in (1.6 mm). At a
tread depth of 0.063 in (1.6 mm), tread
depth indicators (arrow) in the tread-
groove base indicate that the legally-
permissible wear limit has been
reached. Below 0.12 in (3 mm) tread
depth, there is an increased risk of
aquaplaning, even at relatively moder-
ate speeds and with only small amounts
of water on the road.390de331
Do not drive on a deflated (flat)
tire. A flat tire greatly impairs
steering and braking response, and can
lead to complete loss of control over
the vehicle.
Avoid overloading the vehicle so that
the permitted load on the tires is not ex-
ceeded. Overloading can lead to over-
heating and increases the rate at which
damage develops inside the tires. You
could have a blowout as a result.
Unusual vibrations encountered during
normal vehicle operation can indicate
tire failure or some other vehicle defect.
This is also true for irregularities in the
vehicle's handling characteristics, such
as a pronounced tendency to pull to the
left or right. Should this occur, respond
by immediately reducing your speed.
Proceed carefully to the nearest BMW
center or professional tire center, or
have the vehicle towed in to have it and
its tires inspected.
Tire damage (up to and including blow-
outs) can endanger the lives of both the
vehicle occupants and other road
users.<

Tire replacement Tire rotationTire ageThe date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 4100 means that the tire was
manufactured in week 41 of 2000.
BMW recommends the replacement of
all tires when the tires are no more than
6 years old, even if a tire life of 10 years
is possible.
Spare tires over 6 years old should be
used only in case of emergency. A tire
in this condition should be replaced by
a new tire immediately, and should not
be mounted together with new tires.
Between the axlesThe tread wear patterns at the front end
differ from those at the rear Ð the actual
patterns will vary according to individ-
ual driving conditions. In the interests of
safety and maintaining optimal handling
characteristics, tire rotation is not
recommended.
If a proposed interaxle rotation of tires
is based on economic considerations,
one should consider whether the costs
for the rotation are likely to be recap-
tured by any increase in the service life
of the tires that might be realized. In
principle, tire rotation should be per-
formed at short intervals (maximum
3,000 miles/5,000 km). Consult your
BMW center for more information.
Should you decide to rotate the tires,
it is essential to comply with the
following:
Rotate tires on the same side only,
since braking characteristics and road
grip could otherwise be adversely
affected.
Following rotation, the tire inflation
pressure should always be corrected.If different tire sizes are mounted
on the front and rear axles (refer
to page 127), the wheels may not be
rotated from one axle to the other.<

Changing a wheel
Take these precautionary
measures if you have either a flat
tire or are changing the tire:
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat
surface. Switch on the hazard warning
flashers. Turn the steering wheel to the
straight-ahead position, remove the key
and engage the steering lock. Shift into
1st gear or reverse (selector lever in
"Park" with automatic transmission) and
engage the parking brake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area (behind a guardrail,
for instance).
If a warning triangle
or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all safety guidelines and
regulations.
Change the wheel only on a level, firm
surface which is not slippery. Avoid
jacking the vehicle on a soft or slippery
support surface (snow, ice, loose
gravel, etc.), as it could slide sideways.
Position the jack on a firm support
surface. Do not place wooden blocks or
similar objects under the jack. If this is
done, the jack might not be able to
reach its full support capacity because
of the limited height.
Do not lie under the vehicle or start the
engine when the vehicle is supported
by the jack. Failure to comply with this
creates a risk of fatal injury.< Your BMW has a spare tire
or a space-
saver spare tire for temporary use to
ensure your mobility.
To remove the spare tire, lift out
the floor panel in the luggage
compartment completely (refer to
page 41).<

note the position of the tools when you
remove them and return them to their
original position when you are through
using them.
>Jack (1)
Raise the floor panel in the luggage
compartment (refer to page 41) and
loosen the red wing nut (arrow).
When you have completed work,
screw the jack all the way back
down. Fold the handle back and
insert it in its holder.
>Wedge (2)

Procedure1 Read and comply with the safety
precautions provided on the
previous page.
2 Secure the vehicle from rolling:
Place the wedge against the rear
surface of the front tire on the side
opposite the side being raised. If
the vehicle is parked on a down-
ward slope, place the wedge
securely in front of the tire. If the
wheel must be changed on a
surface with a more severe slope,
take additional precautions to
secure the vehicle from rolling.
3 If your wheels are equipped with full
wheel covers
*: reach into the venti-
lation openings and pull off the
cover.

Changing a wheel4 Loosen the lug bolts g turn.
5 Position the jack at the jacking point
closest to the flat tire (refer to the
center illustration) so that the jack
base is vertically below the jacking
point and the entire surface of the
head of the jack will move into the
square recess of the jacking point
(refer to the illustration detail) when
the jack is cranked.
6 Crank the vehicle up until the wheel
in question is raised from the
ground.
7 Unscrew the lug bolts and remove
the wheel.
8 Remove accumulations of mud or
dirt from the mounting surfaces of
the wheel and hub; clean the lug
bolts.462de252
9 Position the new wheel or the
space-saver spare tire on the hub
and screw at least two lug bolts
finger-tight into opposite bolt holes.
10 Screw in the remaining lug bolts.
Tighten all the bolts securely.
11 Lower the jack and remove it from
beneath the vehicle.
12 Tighten the lug bolts in a diagonal
pattern.462de266
13 If your wheels are equipped with full
wheel covers
*: position the wheel
cover with the valve opening over
the valve (arrow) and press it onto
the wheel with both hands.
14 Check and correct the tire's inflation
pressure at the earliest possibility.
For vehicles with Tire Pressure
Control (RDC):
Reactivate the system after
mounting the spare tire or
correcting the air pressure. Refer to
page 85.
Only use original BMW full wheel
covers, otherwise, the trim piece
may not fit securely. The full wheel
cover may not be installed on the
space-saver spare tire since this could
damage the cover.<
