Refueling
Before filling the tank, switch off
the engine, as otherwise fuel
cannot flow into the tank and the
"Service Engine Soon" warning lamp
may come on, refer to page 22.<
Open the fuel filler cap:
To open the fuel filler door, turn the fuel
filler cap counterclockwise and remove
the cap. Place the filler cap in the
bracket attached to the fuel filler door.
Open the filler cap carefully. If you
do not, fuel could spray out.<
To unlock the fuel filler door manually in
the event of an electrical malfunction of
the central locking system, refer to
page 157.
367de391
When refueling, insert the filler nozzle
completely into the filler pipe. Pulling
the nozzle out of the pipe during refu-
eling
>results in premature shutoff
>and will reduce the effect of the vapor
recovery system.
If the filler nozzle is operated correctly,
the fuel tank is full when it shuts off the
first time.
Tank capacity, approx. 13.5 gal.
(51 liters), incl. a reserve capacity of
approx. 2.1 gal. (8 liters).
Close the fuel filler cap:
Position the cap on the neck. Turn the
cap clockwise to the stop.
Close the filler cap carefully after
refueling until a "click" is heard.
While closing, be sure not to squeeze
the strap which is fastened to the cap.
A loose or missing cap will activate the
"Service Engine Soon" lamp.<
Close the fuel filler door.
When handling fuels, comply with
all of the applicable safety
precautions and regulations pertaining
to fuels.
Never carry spare fuel containers in
your vehicle. Whether they are empty or
full, these containers can leak, cause an
explosion, or lead to fire in the event of
a collision.<

the illustration with the ignition key in
position 0 by pressing the button in the
instrument cluster (arrow).2 Trip odometer/Gear indicator

Trip odometer:
To reset the trip odometer to zero,
press the button (arrow) with the igni-
tion key in position 1 or higher.
Gear indicator:
>S for Sport Program
>M1 to M5 for manual mode.367us710
Never allow the engine to operate with
the needle in the red overspeed sector
of the gauge.
To protect the engine, the engine-
management system automatically
interrupts the fuel supply in this range;
you will notice a loss of power.367de005
When you switch on the ignition, the
indicator lamp comes on briefly to
confirm that the system is operational.
Once the indicator lamp stays on
continuously, there are still approx.
2.1 gallons (8 liters) of fuel in the fuel
tank.
Tank capacity: page 173.
If the tilt of the vehicle varies (extended
driving in mountainous areas, for
example), the needle may fluctuate
slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.< 367us006

Wheel and tire combinationsThe 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 the informa-
tion beginning on page 116.
The correct wheel and tire combi-
nation affects different systems
such as ABS and ASC+T/DSC
*. The
function of these systems is impaired if
improper wheel and tire combinations
are used.
For this reason, use only tires of the
same manufacture and tread configura-
tion. In the event of a flat tire, for
example, remount the approved wheel
and tire combination as soon as
possible.<
Codes on tires and wheelsThe code on the 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 149 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = up to 186 mph (300 km/h)
ZR = over 149 mph (240 km/h) Example:
Nominal width
in mm
Aspect ratio in %
Belt rating ID code
for radial tires
Wheel diameter in inches
Load rating
(not on ZR tires)
Speed rating
(before R on ZR tires)
205/60 R 15 91 H
All season and 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 valve inserts against dirt by
using screw-on valve caps. Dirt in the
valve inserts frequently causes a slow
loss in tire pressure.Storage Store tires in a cool, dry place,
protecting them against light whenever
possible. Protect the tires against
contact with oil, grease and fuel. Example:
Rim width
in inches
Code letter for
flange type
Symbol for full-drop
center rim
Rim diameter in inches
