Fuel gauge Temperature gauge When you switch on the ignition, the
indicator lamp comes on briefly to con-
firm that the system is operational.
Once the indicator lamp begins to light
up 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, e.g.,
when you are driving in mountainous
areas, this may cause the needle to
fluctuate slightly.
Please refuel early, as driving to
the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<462us020
BlueThe engine is still cold. Drive at moder-
ate engine and vehicle speeds.RedWhen you switch on the ignition, the
indicator lamp comes on briefly to con-
firm that the system is operational.
If the lamp comes on while operating
the vehicle, the engine is overheated.
Switch the engine off immediately and
allow it to cool down.460de082
Between the blue and red zonesNormal operating range. It is not un-
usual for the needle to rise as far as the
edge of the red zone in response to high
outside temperatures or severe operat-
ing conditions.

Winter operationThe onset of winter is often accompa-
nied by rapid changes in weather. Adap-
tations in driving style should be accom-
panied by preparations on the vehicle
itself to ensure that your progress
through the winter remains safe and
trouble-free.CoolantBe sure that the coolant mixture is kept
at the year-round ratio of 50:50 of water
and antifreeze/corrosion protection.
This mixture provides protection against
freezing down to approx. – 347
(– 376). Replace the coolant every four
years.LocksBMW door lock deicer can be used to
free them if frozen. This deicer also
contains lubricant.
After using deicer, 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.<
Snow chains BMW snow chains
* can be mounted on
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 situation (snow chains mounted),
deactivate the DSC. Refer to page 81.
Starting offWe recommend that you use the man-
ual control switch to deactivate DSC
when starting off in deep snow or when
rocking the car to free it (refer to
page 81).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. Adapt
your speed and driving style when ap-
proaching grades or slopes. Maintain
an adequate distance between yourself
and the car ahead.
BrakesWinter road conditions substantially
reduce the traction available between
the tires and the road surface.
Remember that braking distances will
be significantly longer as a result.
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 in-
crease the pressure, reduce the pres-
sure 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.

Coolant
Do not add coolant to the cooling
system when the engine is hot,
since escaping coolant can cause
burns.
To avoid the possibility of damage later
on, never use anything other than fac-
tory-approved, nitrite- and amino-free
extended-duty antifreeze with corrosion
inhibitor. Your authorized BMW center
is familiar with the official specifica-
tions.
Antifreeze and anticorrosion agents are
hazardous to health. Store antifreeze
and anticorrosion agents in their origi-
nal containers and inaccessible to chil-
dren. Extended-duty antifreeze with
corrosion inhibitor contains the flamma-
ble substance ethyleneglycol. Do not
spill antifreeze containing corrosion
inhibitor on hot engine components,
since it could catch fire and cause seri-
ous burns.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of extended-duty antifreeze with
corrosion inhibitor.<
Checking coolant levelCorrect coolant level when the engine
is cold (approx. 687 or 206):
Unscrew the cap from the expansion
tank.
The coolant level is correct when the
end of the red float is aligned with the
upper edge of the filler opening (refer to
the arrow in the illustration or the sche-
matic diagram next to the cap).460de053
Add coolant Wait until the engine cools before
removing the cap from the expansion
tank. The coolant gauge needle in the
instrument cluster must be located in
the blue field; otherwise, otherwise, you
could be scalded.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape. Then open.
2 If the coolant is low, slowly add
coolant until the correct level is
reached – do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the pre-
scribed all-season 50:50 mixture ratio
for year-round protection against inter-
nal corrosion. No other additives are re-
quired.
Replace the coolant every four years.
