Closing the gas capPlace the cap in position and turn it
until a clearly audible click is heard.
Close the gas 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
CHECK GAS CAP* lamp.<
Warning lamp* lights up. The
gas cap is not properly closed
or is missing. Check if the gas
cap is properly closed.Fuel tank capacity>Approx. 16.6 gal./63 liters, of which
>approx. 2.1 gal./8 liters are reserve
capacity.
Do not drive to the last drop of
fuel. This can prevent the engine
from operating properly and result in
damage.<
Fuel specificationsThe engine uses lead-free gasoline
only.Required fuelPremium Unleaded Gasoline,
Minimum Octane Rating: AKI 91.
Minimum Octane Rating corresponds to
the Anti Knock Index AKI and is deter-
mined according to the so-called
(R+M)/2 method.
Do not use leaded gasoline, as
otherwise the lambda probe and
catalytic converter will be permanently
damaged. cant differences in fuel quality: volatility,
composition, additives, etc., among
gasolines offered for sale in the United
States and Canada. Fuels containing up
to and including 10 % ethanol or other
oxygenates with up to 2.8 % oxygen by
weight, that is, 15 % MTBE or 3 % meth-
anol plus an equivalent amount of co-
solvent, will not void the applicable
warranties with respect to defects in
materials or workmanship.
The use of poor-quality fuels may
result in drivability, starting and
stalling problems especially under cer-
tain environmental conditions such as
high ambient temperature and high alti-
tude.
Should you encounter drivability prob-
lems which you suspect could be
related to the fuel you are using, we
recommend that you respond by
switching to a recognized high-quality
brand.
Failure to comply with these recom-
mendations may also result in unsched-
uled maintenance.<
Refueling

Fuel gaugeOnce the indicator lamp stays on con-
tinuously, there are still approx. 2.1 gal-
lons/8 liters of fuel in the fuel tank.
Fuel tank capacity approx.
16.6 gallons/63 liters.
Certain operating conditions, such as
those encountered in mountainous
areas, may cause the needle to fluctu-
ate slightly.
Fill the fuel tank before it is com-
pletely empty. Driving to the last
drop of fuel can prevent the engine
from operating properly and result in
damage.<
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.
Engine coolant temperature gaugeBlueThe engine is still cold. Drive at moder-
ate engine and vehicle speeds.Between the blue and red zonesNormal operating range. The needle
may rise as far as the edge of the red
sector during normal operation.RedWhen you switch on the ignition, the
warning lamp comes on briefly as an
operation check.
If the lamp comes on during normal
vehicle operation: the engine has over-
heated. Shut off the engine immediately
and allow it to cool down.

Coolant
Do not add coolant to the cooling
system when the engine is hot. If
you attempt to do so, escaping coolant
can cause burns.<
Coolant consists of water as well as an
additive such as antifreeze with corro-
sion inhibitor. Not all commercially
available additives are suitable for your
BMW. Your BMW center knows which
additives are appropriate.
Only use approved additives, as
the engine could otherwise be
damaged. The additives are hazardous
to your health; therefore, follow the
instructions on the containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of antifreeze with corrosion inhib-
itor.<
Checking the coolant level and
adding coolantCheck the coolant level when the
engine is cold, approx. 687/+206.
1. Open the cap for the expansion tank
by turning it slightly counterclock-
wise to allow accumulated pressure
to escape, then open
2. The coolant level is correct when the
upper end of the red float rod – see
arrow – is at least even with the
upper edge of the filler neck, is at
least even with the upper edge of the
filler neck; see arrow. The end of the
float may stick out by a maximum of
3/4 in / 2 cm – that is, up to the sec-
ond mark on the float
3. If necessary, add coolant. If the cool-
ant is low, slowly add coolant until
the correct level is reached – do not
overfill.

function.
Jump-startingWhen your battery is discharged you
can use two jumper cables to start your
vehicle with power from the battery in a
second vehicle. You can also use the
same method to help start another
vehicle. Only use jumper cables with
fully insulated handles on the terminal
clamps.
Do not touch high-voltage wiring
and cables on a running engine.
Contact with components carrying high
voltage can be harmful or fatal. Care-
fully observe the following instructions
to avoid personal injury and/or damage
to one or both vehicles. support vehicle has 12 volts and
approximately the same capacity –
measured in Ah. This information is
provided on the battery
2. Stop the engine of the support vehi-
cle
3. Switch off all electrical components
in both vehicles.
Make absolutely certain that there
is no contact between the body-
work of the two vehicles, otherwise
there is a short circuit hazard.<
Connecting the jumper cables
Always adhere to this sequence
when connecting jumper cables;
failure to observe this procedure can
lead to sparks at the battery terminals
and pose an injury hazard.<
The auxiliary jump-starting terminal
located in your BMW's engine compart-
ment acts as the positive battery termi-
nal. Refer to the engine compartment

The towing vehicle must not be
lighter than the vehicle being
towed; otherwise, vehicle handling can
no longer be controlled.<
The towing eyelets of both vehicles
should be on the same side.
If the tow bar can only be used in a
diagonal position, please note the fol-
lowing:
>Clearance is restricted while you are
driving around corners
>The inclination of the tow bar pro-
duces lateral force.
Only attach the tow bar to the
towing eyelets. Other parts of the
vehicles could otherwise be dam-
aged.<
With a tow ropeWhen the towing vehicle is driving off,
make sure that the tow rope is taut.
Use nylon ropes or straps for tow-
ing because they prevent sudden
jerking movements. Attach the tow rope
only to the towing eyelets. Other parts
of the vehicles could otherwise be
damaged.<
With a tow truckHave the BMW transported by a tow
truck with a lift sling, or on a flatbed.
Never allow passengers to ride in
a towed vehicle for any reason.<
Do not lift the vehicle by the tow-
ing eyelet, nor by parts of the
body or chassis. Otherwise damage
could result. Do not tow-start vehicles with
automatic transmissions. Jump-
starting, refer to page 163.<
