Tire replacement Tire rotation 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.
Sustained high temperature can cause
the tire material to degenerate and
reduce tire life, and excessive tempera-
ture can lead to sudden tire failure. The
Grade C corresponds to a level of
performance which all passenger
vehicle tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this
tire is established for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possibly a flat tire.<
Uniform Tire Quality GradingQuality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
Tread wear 200 Traction AA
Temperature A
Use only tires with emergency
driving characteristics as there is
no spare tire available if you get a flat
tire. For further information, refer to
page 135. factured is indicated by the code on the
sidewall:
DOT ... 1200 indicates that the tire was
manufactured in week 12 of 2000.
Although tires may have a theoretical
service life of up to 10 years, BMW
strongly recommends that you replace
all tires after an absolute maximum of
6 years.
Between the axles
If different tire sizes are mounted
on the front and rear axles (refer to
page 103), then the tires may not be
rotated from one axle to the other.<
The tread wear patterns at the front end
differ from those at the rear Ð the actual
patterns will vary according to indi-
vidual driving conditions. In the inter-
ests of safety and maintaining optimal
handling characteristics, tire rotation is
not recommended.

Wheel and tire combinations 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.<
For wheel and tire specifications
approved by BMW, refer to page 103.
The correct wheel-tire combina-
tion affects different systems that
otherwise will not function properly,
e.g. ABS, DSC and RDW.
For this reason, use only tires of the
same brand and tread pattern on the
vehicle and, for example, restore the
approved wheel-tire combination
following a flat tire as soon as
possible.<
Codes on tires and wheels The code on tires has the following
meaning.
Codes on radial tires:
The speed rating indicates the approved
maximum speed for the tire.
Summer tires:
S = up to 112 mph (180 km/h)
T = up to 118 mph (190 km/h)
H = up to 130 mph (210 km/h)
V = up to 150 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = up to 186 mph (300 km/h)
ZR = over 150 mph (240 km/h) For example:
Nominal width
in mm
Aspect ratio in X
Radial tire code
Rim diameter in inches
Load rating
(not on ZR tires)
Speed rating
(before R on ZR tires)
245/45 R 18 96 W
Winter tires:
Q M+S = up to 100 mph (160 km/h)
T M+S = up to 118 mph (190 km/h)
H M+S = up to 130 mph (210 km/h)
Codes on light-alloy wheels:
Protect tire valves from dirt by using
screw-on valve stem caps. Dirt in the
valves frequently leads to slow leaks.
Tires with emergency driving character-
istics also possess an additional identi-
fication mark that varies by manufac-
turer, e. g.:
Bridgestone RFT
Dunlop DSST
Goodyear EMT
Michelin ZPStorage Store tires in a cool, dry place,
protecting them against light when-
ever possible. Protect the tires against
contact with oil, grease and fuel. For example:
Rim width
in inches
Code letter for
flange type
Symbol for full-drop
center rim
Rim diameter in inches
Hump on the 2 rim shoulders

Coolant Brake fluidAdding coolant To guard against the possibility of
scalding injuries, always wait until the
engine cools (temperature gauge
needle in blue sector) before
unscrewing the cap on the expansion
tank.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape, then continue
turning to remove.
2 If the coolant is low, slowly add
coolant until the correct level is
reached Ð do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the
prescribed all-season 50:50 mixture
ratio for year-round protection against
internal corrosion. No other additives
are required.
Replace the coolant every three years.The brake warning lamp comes on and
the parking brake has been released:
Check the brake fluid level. Fill it to the
top mark ("MAX") if necessary.
For adding brake fluid or for deter-
mining and correcting the cause of
brake fluid loss, consult your BMW
center. Your BMW center is familiar
with the specifications for factory-
approved brake fluids (DOT 4).
Brake fluid loss can increase brake
pedal travel. For this type of situation,
refer to the notes on page 91.
520de157
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
a BMW center. Refer also to the Service
and Warranty Information Booklet (US
models) or the Warranty and Service
Guide Booklet (Canadian models).
Brake fluid is toxic and attacks the
vehicle's paintwork. You should always
store it in its original container and in a
location that is inaccessible to children.
Do not spill the 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.<

Battery
Battery posts, terminals, and
related accessories contain lead
and lead compounds. Wash hands after
handling.<
Installation location The battery is located under the
luggage compartment's floor panel.Charge conditionYou can read the charge condition
of the battery with the "Magic Eye"
hydrometer (arrow):
>Green: adequate charge
>Black: not charged adequately. The
battery must be recharged. Please
contact your BMW center for addi-
tional information
>Yellow: replace the battery.520de076
The service life specified for the
battery can be achieved only if it is
always kept adequately charged. If the
vehicle is primarily used for stop-and-
go traffic, be sure to check the charge
state often.<
MaintenanceThe battery is completely maintenance-
free. That means that the original
battery acid will normally last for the
service life of the battery under
moderate climate conditions.
For all questions regarding the
battery, please consult your BMW
center. Since the battery is absolutely
maintenance-free, the following is for
your information only. your vehicle battery. To avoid injury,
please comply with the following
precautions whenever you work with or
near the battery.
Before handling the battery,
please read the following infor-
mation.
Wear eye protection. Do not
allow particles containing
battery acid or lead to come into
contact with eyes, skin, or clothing.
Battery acid is extremely corro-
sive. Wear eye protection and
protective gloves. Do not tip the
battery. Battery acid can leak from the
ventilation openings.
Be sure that children keep well
away from batteries and battery
acid.
Never allow sparks or open
flame near the battery. Do not
smoke in the vicinity of the
battery. Avoid creating sparks when
working around electrical cables or
equipment. Turn the key to position 0 in
the ignition when disconnecting or
connecting the battery. Do not short-
circuit the battery terminals. This
creates a risk of injury from high-energy
sparks.

Towing the vehicle
Avoid "off-center" towing. Be sure
that the tow rope is pulled tightly
when the towing vehicle begins to
move.<
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it is no longer
possible to control vehicle response.<
Tow-startingFor instructions on jump starting, refer
to page 143.
Never attempt to use your vehicle to
push another vehicle, since damage to
the energy-absorbing bumpers could
result.
Towing a vehicle1 Put the manual-shift gear 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 in position 1
to ensure that the brake lamps, turn
signals, horn and windshield wipers
remain operative, and to prevent the
steering lock detent from engaging
5 Switch on the hazard-warning system
(comply with country-specific regula-
tions).
Find some means of identifying the
vehicle in tow, e. g. 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
not running. This means that increased
effort is required for steering and
braking.<
Towing with a commercial tow
truck>Do not tow with sling-type equipment
>Use a wheel lift or flat bed equipment
>Please comply with applicable towing
laws.
Never allow passengers to ride in a
towed vehicle for any reason.<520us014
