Winter operationThe onset of winter is often accompa-
nied by rapid changes in weather.
Adaptations in driving style should be
accompanied by preparations on the
vehicle itself to ensure that your vehicle
operation through the winter remains
safe and trouble-free.CoolantEnsure that the coolant contains the
year-round 50 : 50 ratio of water and
antifreeze with corrosion inhibitor. This
mixture provides protection against
freezing down to approx. Ð 34 7
(Ð 37 6). Replace the coolant every
three years.LocksBMW door lock deicer can be used to
free the doors if they are frozen. This
deicer also contains lubricant.
After using deicer, treatment with BMW
lock cylinder grease is recommended.
Rubber seals and components In order to prevent freezing, apply BMW
rubber treatment to weather-stripping
on the doors, hood, luggage compart-
ment and to convertible top seals.
A full range of car-care products is
available from your BMW center.< Snow chainsBMW snow chains
* can be mounted on
both summer and winter tires. Mount
them in pairs on the rear wheels only.
Comply with the manufacturer's safety
precautions. Do not exceed a speed
limit of 30 mph (50 km/h) when driving
with chains. As an exception in this
situation, we recommend that you
switch off the ASC+T/DSC
* system
when snow chains are mounted. Refer
to pages 73, 74.
Starting offWhen starting from a full stop or
"rocking" free in deep snow, we recom-
mend that you switch off the ASC+T/
DSC
* system, refer to pages 73, 74.
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. Shift down
into the next lowest gear when
approaching uphill or downhill grades.
Maintain an adequate distance between
yourself and the vehicle ahead.Brakes Winter road conditions substantially
reduce the traction available between
the tires and the road surface.
Remember that Ð in every situation Ð
braking distances will be significantly
longer as a result of this.
ABS is intended to prevent the wheels
from locking during brake applications,
thus helping to maintain vehicle stability
and steering response.

Tire replacementTractionThe traction grades, from highest to
lowest, are AA, A, B and C.
Those grades represent the tire's ability
to stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests, and does
not include acceleration, cornering,
hydroplaning, or peak traction charac-
teristics.<
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 material of the tire to degenerate
and reduce tire life, and excessive
temperature 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, under-inflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible tire failure.<
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
Do not use retreaded tires as this
could negatively affect driving
safety. This is due to the possible varia-
tions in casing structures and, in some
cases, to their extreme age, factors
which can lead to a decrease in their
durability.<

Airbags Storing your vehicle1 Front airbags on the driver and
passenger side
2 Side airbags on the driver and
passenger sideImportant safety notices
Do not attempt to remove the gas
generators of the airbag restraint
system from the vehicle or to disas-
semble them.
Have inspection and service proce-
dures performed by specially-trained
personnel only.
If the airbag restraint system malfunc-
tions, is deactivated or triggered as a
response to an accident, have the
system repaired by a BMW center only.
367de730
Do not make modifications of any kind
to the individual components or system
wiring. These include the upholstered
covers on the steering wheel hub, in the
instrument panel and in the side trim
panels of the doors. Never apply adhe-
sive materials to these components or
cover or modify them in any way. Do
not attempt to disassemble the steering
wheel itself.
To ensure compliance with applicable
safety regulations, have the airbag
generators disposed of by a BMW
center only.
Unprofessional attempts to service the
system could lead to failure in an emer-
gency or undesired airbag activation,
either of which could result in personal
injury.< If you intend to store the vehicle
for longer than three months, have
the maintenance operations described
on this page performed.<
Preparation for storageHave the following operations
performed by your BMW center:
1. Clean and apply a rust-proofing
agent or other treatment to the
engine, engine compartment, under-
carriage, axles and major compo-
nents in accordance with approved
repair procedures. Wash the vehicle,
clean the interior and treat painted
and chromed parts. Clean the rubber
seals around the hood, luggage
compartment and doors
2. Change the engine oil and oil filter
with the engine at operating temper-
ature. As an additional corrosion
protection measure, an anticorrosive
agent can be added to the engine in
accordance with the manufacturer's
instructions
3. Check the coolant level and concen-
tration and top up if necessary
4. Check the fluid level of the wind-
shield washer fluid reservoir; top up if
necessary

Remote controlChanging batteryRenew when the LED no longer lights
up when a button is pressed and it is
not possible to lock the vehicle using
the remote key.
Install only a battery of the specification
(CR 2016) indicated in the battery
compartment and make sure that the
battery is installed in the correct posi-
tion.
1. Use a screwdriver to lift the cover at
the recess (arrow)365de017
2. Loosen the two screws (arrows) and
remove the cover.
The battery type and its installation
position are stamped into the base of
the battery compartment.
Return used batteries to a recy-
cling point or your BMW center.< 365de018
New master key with remote
controlIf you place a new master key with
remote control into service (either a
replacement or an additional key), it
must be initialized together with all
existing master keys (with remote
control):
1. Have all existing master keys with
remote control as well as the spare-
or ignition key present, refer to
page 30
2. Enter the vehicle and close the doors
3. Briefly turn the spare key 2 or the
ignition key 3 (max. 5 seconds) to
position 1 in the steering lock, then
return it to position 0365de126

Remote control4. Press and hold down button 1 (see
illustration). Maintain pressure on
button 1 while rapidly pressing
button 2 three times in succession
within a period of 10 seconds
5. Release button 1. LED 3 flashes
slowly for a maximum of 10 seconds
6. The central locking system engages
and releases all lock mechanisms in
rapid succession to indicate that the
initialization procedure has been
successfully completed.
If the LED does not flash or if the
central locking system fails to respond,
the initialization procedure will have to
be repeated.
All additional master keys with remote
control for your vehicle (up to a
maximum of four units) must now be
initialized. Make sure that no more than
30 seconds is allowed to elapse
between the individual initialization
procedures. Repeat steps 4 and 5. The
central locking system will respond to
each initialization procedure as
descriped in step 6.
In the event of a system malfunction,
please contact your BMW center, who
can also provide you with replacement
keys.Turn each new master key into
ignition position 2 (ignition
switched on) and back again to allow
the electronic vehicle immobilizer (refer
to page 31) to recognize the new key.
To prevent unauthorized use of the
master key, surrender only the door and
ignition key 3 or the spare key 2 (refer
to page 30) for valet parking, for
instance.<
