Tire Pressure Warning (RDW)The conceptRDW monitors the tire pressure in all
four wheels while driving. The system
provides an alert whenever the inflation
pressure drops significantly in one of
the tires.
For RDW to "learn" the correct tire infla-
tion pressure, check the inflation pres-
sure in all tires, comparing them with
the values in the inflation pressure table
(refer to page 27), and make correc-
tions as necessary. Then activate the
system.
The indicator lamp within the in-
strument cluster flashes to alert
you to substantial pressure loss
in any of the tires.
To activate the system 1 Turn the ignition key to position 2
2 Press the switch long enough for
the indicator lamp in the instrument
cluster to light up red for a few
seconds
3 RDW carries out an automatic
initialization process while you are
driving, and stores this data to aim for
optimal conditions. This one-time
"learning" process lasts at least
10 minutes, after which the RDW is
able to detect and report a flat tire.520de117
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement.
Do not reactivate the system after
periodic corrections of inflation pres-
sures to maintain them at the levels
stored during an earlier initialization
process.

Brake system Winter operationBrake 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 antifreeze/corrosion protec-
tion. This mixture provides protection
against freezing down to approx. Ð 34 7
(Ð 37 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.
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. * only in pairs
on the rear wheels with approved winter
tires. Always follow the manufacturer's
safety precautions. Do not exceed a
maximum speed of 30 mph (50 km/h).
Do not activate the RDW system while
using snow chains. Malfunction warn-
ings and undetected losses in pressure
are possible when driving with snow
chains.
Starting offWhen starting off in deep snow or when
"rocking" the vehicle to free it, it may be
advisable to temporarily deactivate the
DSC system. Refer to page 65.
To maintain vehicle stability,
always drive with the system
switched on whenever possible.<

Special features of winter tires Snow chains
*
Choosing the right tireFor winter road driving, BMW recom-
mends winter tires (M+S radial belt
tires). Although all-season M+S tires
provide better winter traction than stan-
dard summer tires with H, V, W and ZR
speed ratings, they generally fail to
provide the same levels of performance
as standard snow tires in winter driving.
In the interests of safe tracking and
steering response, install radial tires
made by the same manufacturer and
with the same tread configuration on all
four wheels if you elect to mount winter
tires.
Use only winter tires with emer-
gency driving characteristics as
there is no spare tire available if you get
a flat tire.
For further information, refer to
page 135.<
Do not exceed specified
maximum speeds
Never exceed the maximum speed
for which winter tires are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Your BMW center
will be glad to assist you with both their
expertise and the proper equipment for
your vehicle.<
Tire condition, tire pressureOnce the tread depth on winter tires is
less than 0.16 in (4 mm), they are no
longer suitable for winter road driving,
and in the interest of safety should be
replaced.
Comply with the specified tire inflation
pressures Ð and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.
The use of narrow-link BMW snow
chains is permissible in pairs only on
the rear wheels with winter tires with
tire size 245/45 R 18 96 H. Comply with
all manufacturer's safety precautions
when mounting the chains.
Do not activate the RDW system
while using snow chains.
Malfunction warnings and undetected
losses in pressure are possible when
driving with snow chains.
For further information, refer to
page 67.<

Vehicle storage
If the vehicle is to be stored for
more than three months, ensure
that the following service operations
are carried out first.<
Preparations for storageHave your BMW center perform the
following procedures:
1 Clean and apply a rust proofing agent
or other treatment to the engine,
engine compartment, undercarriage,
axles and major components in accor-
dance with approved repair proce-
dures. Wash the vehicle, clean the
interior and treat painted and
chromed parts. Clean the weather-
stripping around the hood, luggage
compartment and doors
2 Change engine oil and oil filter at
operating temperature. As an addi-
tional 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 off if necessary
4 Check the fluid level of the wind-
shield washer fluid reservoir; top off
if necessary
5 Fill the fuel tank completely to
prevent the formation of condensa-
tion
6 Increase the tire inflation pressure to
51 psi (350 kPa).Before parking the vehicle1 Dry the parking brake and footbrake
by brake applications to prevent the
brake discs and drums from
corroding
2 Park the vehicle in a covered, dry,
and well-ventilated area. Place the
transmission in first gear or, if neces-
sary, chock the wheels to prevent the
vehicle from rolling. Do not engage
the parking brake
3 Remove the battery, charge it
completely and store it in a cool (but
frost-free) room
4 Remove the hardtop and store it
separately, refer to page 96
5 Close the convertible top.
During storageRecharge a battery that has been taken
out of the car every six months. If it is
not recharged, it will not be serviceable.
Every time the battery is discharged,
especially over extended periods, its
service life is reduced.Removing the vehicle from
storageRecharge the battery if the "Magic Eye"
turns black, refer to page 136.
Then have Inspection I performed by
your BMW center, including a brake
fluid replacement, if necessary. Refer to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).
