Wheels and tires
196
Recommended tire brands
Certain makes of tire are recommended by
BMW for each tire size. They are marked with a
clearly visible BMW designation on the sidewall
of the tire.
When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Special characteristics of winter tires
BMW recommends winter tires for winter roads
or at temperatures below +45 7/+7 6.
Although all-season M+ S tires provide better
winter traction than summer tires, they gener-
ally fail to provide the same levels of cold-
weather performance as winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and acci-
dents. <
If the car is capable of speeds higher than that
permitted for the winter ti res, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your BMW center
can supply these labels.
Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as possible.
Always protect tires agains t all contact with oil,
grease and fuels. Do not exceed the maximum
tire inflation pressure indicated on the sidewall
of the tire.
Swapping wheels between axles
BMW advises against swapping wheels
between the front and rear axles, even if all tires
have the same size, as th is could impair driving
characteristics. If the tires are of mixed sizes,
swapping wheels betwee n the axles is not per-
missible.
Snow chains*
Only certain fine-link sn ow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your BMW center for
more information.
Snow chains must be mounted in pairs and on
the rear wheels only. Observe the manufac-
turer's instructions when mounting snow
chains. Do not exceed a speed of 30 mph or
50 km/h.
Do not initialize the Flat Tire Monitor if
snow chains are mounted, otherwise the
instrument might issue an incorrect reading.
When driving with snow chains, you may find it
helpful to activate DTC temporarily, refer to
page 78.<

Checking coolant level
1.Do not open the engine hood before the
engine has cooled down.
2. Turn the expansion tank cap counterclock-
wise slightly to allo w any accumulated pres-
sure to escape, then continue turning
to open.
3. The coolant level is correct if it is between
the maximum and minimum marks in the
filler neck, refer also to the diagram next to
the filler neck.
4. If the coolant is low, slowly add coolant up to
the specified level; do not overfill.
5. Turn the cap until there is an audible click.
6. Have the reason for the coolant loss elimi-
nated as soon as possible.

underneath a cover.
Exhaust emission values
The warning lamp lights up:
The vehicle emissions are raised. The
trip can be continued. Have the car
checked as soon as possible.
Canadian models display this
warning lamp.
The lamp flashes under certain condi-
tions. This indicates excessive misfiring in the
engine. If this happens, you should reduce your
speed and visit your nearest BMW center as
soon as possible. Severe engine misfiring can
quickly lead to serious damage of emissions-
related components, espe cially the catalytic
converter.
The warning lamp comes on if the gas
cap is not properly tightened and the
OBD system assumes that fuel vapor
is escaping. If the gas ca p is then tightened, the
warning lamp should go out within a few days.
Data recorders
Your vehicle may be equipped with one or sev-
eral measuring or diagnostic modules or a
device for recording or sending certain vehicle
data or information. In addition, if you have
signed a service contract for BMW Assist, cer-
tain vehicle data may be transmitted or
recorded in order to fa cilitate the corresponding
services.

7-gear sport automatic transmission
with dual clutch
Before driving into an automatic car wash, per-
form the following steps to ensure that the vehi-
cle can roll:
1. Insert the remote control, even with conve-
nient access, into the ignition lock.
2. Engage transmission position N.
3. Release the parking brake.
4. Switch off the engine.
5. Leave the remote control in the ignition lock
so that the vehicle can roll.
Transmission position P is engaged:

ignition lock
Steam jets / high -pressure washers
When using steam jets or high-pressure
washers, ensure that you maintain suffi-
cient clearance to the vehicle and do not exceed
a temperature of 60°C.
Insufficient clearance or excessive pressure or
temperature can lead to component damage or
water penetration. Follow the operating instruc-
tions of the high-pressure washer. <
When using high-pressure washers, do
not spray against the seals of the retract-
able hardtop, the sensor s and the cameras, e.g.
of the Park Distance Control or Rear View Cam-
era, for an extended period and maintain a dis-
tance of at least 12 in/30 cm. <
Manual car wash
When washing the vehicle by hand, use large
quantities of water and car shampoo if neces-
sary. Clean the vehicle with a sponge or wash-
ing brush, applying light pressure only.
Before cleaning the windshield, deacti-
vate the rain sensor or switch off the igni-
tion to prevent unintent ional activation of the
wipers. <
Observe local regulations pertaining to
washing vehicles by hand. <
Headlamps
Do not rub them dry and do not use abrasive or
corrosive cleaning agents.
Remove contamination, such as insects, by
soaking with shampoo or insect remover and
then rinsing with plenty of water.
Thaw ice with a windshield de-icer and do not
use an ice scraper.
Windows
Clean the inside and outside surfaces of the
windows and the mirrors with window cleaner.
Do not clean the mirrors with cleaners
containing quartz. <
Retractable hardtop
Proceed as you would in a normal car wash.
When you open a we t hardtop, water
drops may run into the cargo bay. If nec-
essary, remove items from the cargo bay
beforehand to avoid water stains or soiling. <
Paintwork care
Regular care contributes to value retention and
protects the paintwork against the long-term
effects of damaging substances.
Region-specific environmental influences can
damage the vehicle paintwork. Therefore, it is
important to adapt the frequency and scope of
car care accordingly.
Immediately remove aggressive materials such
as spilled fuel, oil, grease, brake fluid, tree sap or
bird droppings to prevent damage to the
paintwork.
Repairing paintwork damage
Immediately repair scratches or similar
damage, such as that caused by stones
hitting the vehicle, wher e necessary to prevent
rusting. <
BMW recommends having paintwork damage
repaired by a profession al paint repair work-
shop according to BMW specifications using
original BMW paint materials.

Care
206
Preservation
A preservation treatment is necessary when
water no longer beads o ff of the clean paintwork
surface. Only use products for paintwork pres-
ervation that contain carnauba or synthetic
waxes.
Rubber seals
Treat only with water or rubber care products.
Do not use silicon-con taining care prod-
ucts on rubber seals; otherwise, noise
and damage could occur. <
Chrome parts
Carefully clean vehicle parts, such as the radia-
tor grill, door handles or window frames, with
copious quantities of water and a shampoo
additive. For additional treatment, use a chrome
polish.
Light-alloy wheels
For technical reasons, dust is generated during
braking that is deposited on the light-alloy
wheels. Remove the dust regularly using acid-
free rim cleaner.
Do not use aggressive, acidic, strongly
alkaline and abrasive cleaning agents or
steam jets over 140 7/60 6, otherwise dam-
age may occur. <
Outside sensors / cameras
Keep the sensors and cameras on the
outside of the vehicle, e.g. those of Park
Distance Control, clean and free of ice to ensure
that they remain fully functional. <
Interior care
Upholstery / cloth trim
Vacuum regularly with a vacuum cleaner to
remove superficial dirt.
To treat severe stains, e.g. from beverages, use
a soft sponge or lint-free microfiber cloth in
combination with suitable interior cleaners. Fol-
low the instructions on the packaging. Clean the upholstery
down to the seams
using a sweeping motion. Avoid strong
rubbing. <
Opened Velcro fasteners, etc., on pants
or other articles of clothing can damage
the seat covers. Ensure that Velcro fasteners
are closed. <
Leather / leather trim
The leather used by BM W is a high quality
natural product. Slight irregularities in the
leather are a typical char acteristic of natural
leather.<
Dust and road grit in th e pores and folds of the
leather have an abrasive effect, leading to
increased wear and caus ing the leather surface
to become brittle prematurely. Therefore, regu-
larly dust the leather with a cloth, for example.
In particular, ensure that light-colored leather is
cleaned regularly as it has a tendency to soil
more easily.
Treat the leather at least twice a year using a
suitable leather lotion, as dirt and grease will
gradually attack the leather's protective layer.
Rivets, etc., on pants or other articles of
clothing can damage the seat covers. <
Carpets / cargo bay
You can vacuum the carpets and floor mats or
clean them with interior cleaner if heavily soiled.
The floor mats can be removed for cleaning.
When replacing the mats, ensure that the seat
rails do not extend over the floor mats, as this
may damage the mats.
Lint on the floor mats occurs for technical rea-
sons and can be re moved by vacuuming
repeatedly.
When cleaning the interior, do not move
both seats all the wa y forward while mov-
ing them to their uppermost position and lean-
ing the backrests forward. Otherwise, the seats
could hit and damage th e seal on the wind-
shield, the sun visor or the headliner. <

Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to vehicle safety. They should, therefore,
be handled carefully. BMW recommends hav- ing your BMW center perform any work that you
do not feel competent to
perform yourself or
that is not described here.
Never touch the glass of new bulbs with
your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life. Use a
clean tissue, cloth or something similar, or hold
the bulb by its base. <
You can obtain a selection of replacement bulbs
at your BMW center.
Only change bulbs while they are cool to
the touch, otherwise you could suffer
burns. <
When working on electrical systems,
always begin by switching off the con-
sumer in question, otherwise short-circuits
could result. To avoid possible injury or equip-
ment damage when replacing bulbs, observe
any instructions provided by the bulb manufac-
turer.<
For care of the headlamps, please follow the
instructions in the chapter entitled 'Care'.
If the routine for changing a particular
bulb is not described here, please contact
your BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel. <
Light-emitting diodes LED
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially desi gnated as Class 1 light-
emitting diodes.
Do not remove the covers or expose the
eyes directly to the unfiltered light source
for several hours, othe rwise this could cause
irritation to the retina. <
