Brake system Winter operationBrake fluid level
The brake warning lamp comes
on with the parking brake
released:
The brake fluid level in the
reservoir is too low, refer to
page 114.
If the brake fluid level is too low and
brake pedal travel has become notice-
ably longer, there may be a defect in
one of the brake system's hydraulic
circuits.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and brake pedal travel may
be significantly longer. Please
remember to adapt your driving style
accordingly.<
Brake pads
The warning lamp for the brake
pads comes on:
The brake pads have reached
their minimum thickness. Proceed to
the nearest BMW center as soon as
possible to have the pads replaced.
For your own safety: use only
brake pads which BMW has
approved for your specific vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
Winter is often accompanied by rapid
changes in weather, requiring not only a
different driving style, but also certain
preparations to the vehicle itself to
ensure that your progress through the
winter months remains safe and
trouble-free. CoolantBe sure that the coolant mixture
contains the year-round ratio of 50:50
water and extended-duty antifreeze
with corrosion inhibitor. This mixture
provides protection against freezing
down to approx. Ð34 7 (Ð37 6).LocksBMW door lock deicer can be used to
free doors if frozen. This deicer also
contains lubricant.
After using the deicer, treatment with
BMW lock cylinder grease is recom-
mended.

on rear tires, complying with the manu-
facturer's safety precautions. Do not
exceed a maximum speed of 30 mph
(50 km/h) while the snow chains are
mounted and refrain from activating the
Flat Tire Monitor, as the snow chains
could trigger false alarms and/or
prevent the system from detecting
actual pressure loss.
Starting off When starting off in deep snow or when
"rocking" the vehicle to free it, it may be
advisable to temporarily deactivate the
DSC. Refer to page 65.
To maintain vehicle stability,
always drive with the system
switched on whenever possible.<
Driving on low-traction road
surfaces Do not activate the Sport mode (refer to
page 66). Use smooth, gentle pressure
to control the accelerator pedal. Avoid
excessive engine speeds and upshift
early. Downshift well in advance when
approaching uphill or downhill grades.
Maintain an adequate distance
between yourself and the vehicle
ahead. BrakesWinter road conditions substantially
reduce the amount of traction available
between the tires and the road surface.
The resulting increases in braking
distance are considerable and should
be kept in mind at all times.
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 increase the pressure, reduce the
pressure when the wheels lock, reapply
pressure etc.
This staggered braking procedure will
reduce braking distances while helping
you maintain steering control.
You can always then attempt to steer
around hazards after you have reduced
pressure on the brake pedal.
Never downshift to exploit engine
braking when driving on slippery
road surfaces, as this could lead to a
loss of traction at the rear wheels,
impairing your ability to control the
vehicle.<
Depress the clutch during hard
braking on road surfaces that
provide only poor or uneven traction.<

Winter operation Power steering Cellular phone Skid control Depress the clutch and release the
accelerator pedal. Countersteer care-
fully and attempt to regain control over
the vehicle.ParkingEngage first or reverse gear. Depending
on the steepness of the incline, you can
apply the parking brake as well. In order
to prevent the parking brake pads from
locking due to frost or corrosion, dry
them by gently applying the parking
brake as the vehicle is coming to a
stop. Make sure that following traffic is
not endangered.
The brake lamps do not come
on when the parking brake is
engaged.<
If there is a change in steering response
Ð e. g. difficult or over-responsive
steering Ð at increasing speeds, consult
a BMW center to have it checked.
If the power steering fails,
increased effort will be required to
steer the vehicle.<
Mobile communications systems
(cellular phone, radio, etc.) are
permitted with an output of up to
10 watts only. Mobile communications
devices not specifically designed for
use in your vehicle may trigger malfunc-
tions while you are operating your
vehicle. BMW can neither test nor
assume responsibility for every indi-
vidual product being offered on the
market. We recommend that you
consult your BMW center before
purchasing any device of this kind.
To ensure reliable and trouble-free
operation of your BMW, do not use any
cellular phones or other radio devices
where the antenna is located either
inside the passenger compartment or
otherwise not attached to the outside of
the vehicle.
You will find instructions for operating
your cellular phone in the supplemen-
tary Owner's Manual.

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 open
2. 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:
The brake fluid is too low.
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 92.
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.<
