Technology for comfort, convenience and safety
94 1.Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steer-
ing maneuvers. Do not exceed a speed of
50 mph/80 km/h.
Stop driving if the vehicle is no longer
equipped with run-flat tires, as it was
when it came from the factory, refer to
page218. Continued driving after a flat tire
can result in serious accidents.<
2.In the event of complete tire pressure loss,
0 psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guide values:
>With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
>With a medium load:
2 persons, cargo bay full, or
4 persons without luggage:
approx. 95 miles/150 km
>With a full load:
4 persons, luggage compartment full:
approx. 30 miles/50 km
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. In the event of
pressure loss, vehicle handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
If unusual vibrations or loud noises occur while
the vehicle is being driven, this can indicate final
failure of the damaged tire. Reduce speed and
stop at a suitable location as soon as possible,
otherwise pieces of the tire could become
detached and cause an accident. Do not con-
tinue driving, but instead contact your BMW
center.<
Malfunction
The yellow warning lamp flashes and
then lights up continuously. The tires
are shown in gray on the Control Dis-
play and a message is displayed. No flat tire can
be detected.
A message like this is displayed in the following
situations:>In case of a malfunction;
have the system checked.
>If a wheel is mounted without TPM elec-
tronics.
>If TPM is temporarily interfered with by
other systems or devices which use the
same radio frequency.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire should be checked monthly when cold
and inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. If
your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire infla-
tion pressure label, you should determine the
proper tire inflation pressure for those tires. As
an added safety feature, your vehicle has been
equipped with a tire pressure monitoring sys-
tem, TPMS, that illuminates a low tire pressure
telltale when one or more of your tires are signif-
icantly underinflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle's han-
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte-
nance, and it is the driver's responsibility to
maintain correct tire pressure, even if underin-
flation has not reached the level to trigger illumi-
nation of the TPMS low tire pressure telltale.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle startups as
long as the malfunction exists. When the mal-
function indicator lights up, the system may not
be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of

Things to remember when driving

Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. To ensure that your vehicle contin-
ues to provide optimized economy of operation
throughout an extended service life, we request
that you devote careful attention to the follow-
ing section.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at changing engine and driving speeds,
however do not exceed 4,500 rpm or 100 mph/
160 km/h.
Avoid full-throttle operation and use of the
transmission's kick-down mode during these
initial miles.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive reservedly during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive in a reserved manner during
this break-in period.
Clutch
The function of the clutch is only at its opti-
mized level after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
Observe the break-in instructions again if com-
ponents mentioned above must be replaced
after subsequent driving operation.
Saving fuel
The fuel consumption of your vehicle depends
on various factors. Through a few simple steps,
your driving style, and regular maintenance, you
can have a positive influence on your fuel con-
sumption and environmental impact.
Removing unnecessary cargo
Additional weight increases fuel consumption.
Removing add-on parts after use
Remove unneeded auxiliary mirrors, roof or rear
luggage racks after use. Add-on parts attached
to the vehicle impede the aerodynamics and
increase the fuel consumption.
Closing windows and glass sunroof
An open glass sunroof or open windows like-
wise increase the drag coefficient and therefore
the fuel consumption.
Checking tire inflation pressures
regularly
Check and correct the tire inflation pressure as
needed at least twice a month and before long
trips.
An insufficient tire inflation pressure increases
the rolling resistance and thus increases the
fuel consumption and tire wear.
Driving off immediately
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive at a moderate engine
speed. This is the fastest way for the cold
engine to reach its operating temperature.

Thinking ahead when driving
Avoid unnecessary acceleration and braking.
To do so, maintain the appropriate distance
from the vehicle in front of you. An anticipatory
and smooth driving style reduces fuel con-
sumption.
Avoiding high engine speeds
Use 1st gear only for starting off. Accelerate
rapidly in 2nd gear and above. Avoid high
engine speeds in doing so and shift into the
next gear early.
When you have reached the desired speed,
shift into the highest possible gear and drive
with the lowest possible engine speed while
maintaining a constant a vehicle speed.
In general: driving at a low engine speed
reduces fuel consumption and minimizes wear.
Taking advantage of coasting
When approaching a red light, let off the gas
and allow the vehicle to coast to a stop in the
highest possible gear.
On steep roadways, let off the gas and allow the
vehicle to roll in the appropriate gear.
The flow of fuel is interrupted when coasting.
Switching off the engine during longer
stops
Switch off the engine at longer stops such as
traffic signals, railroad crossings, or in traffic
jams. Even having the engine switched off for
approx. 4 seconds results in fuel savings.
Switching off functions currently not
required
Functions such as the cooling function of the
automatic climate control, seat heating or rear
window defroster draw large amounts of power
and consume additional fuel. Their influence is
particularly pronounced in city traffic and stop &
go operation. For this reason, it is a good idea to
switch these functions off when they are not
really needed.
Having maintenance carried out
Have the vehicle serviced regularly in order to
achieve the optimum economy and service life
of your vehicle. BMW recommends having the
maintenance performed by a BMW center. Also
please pay attention to the BMW maintenance
system, refer to page225.
General driving notes
Closing luggage compartment lid
Only drive with the luggage compartment
lid completely closed, otherwise exhaust
can penetrate into the passenger compart-
ment.<
If it is absolutely necessary to drive with the lug-
gage compartment lid open:
1.Coupe: close both windows and the glass
sunroof.
Convertible: with closed top, close all win-
dows.
2.Increase the air volume of the automatic cli-
mate control to a high level, refer to
page112.
Hot exhaust system
As in all vehicles, extremely high temper-
atures are generated on the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to it, and never apply undercoating to
them. When driving, standing at idle and while
parking take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, and with it
the risk of serious property damage as well as
personal injury. Do not touch hot exhaust tail
pipes. Otherwise there is a risk of burns.<
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between the tires and

Refueling
Switch off the engine before refueling,
otherwise no fuel can be filled into the
tank and a message is displayed.<
When handling fuel, always observe all
applicable precautionary measures and
regulations. Never transport reserve fuel con-
tainers in the vehicle. They can leak and cause
an explosion or a fire in an accident.<
Fuel filler door
To open and close: briefly press the rear edge of
the fuel filler door.
Unlocking manually
In the event of an electrical malfunction, you can
release the fuel filler door manually:
In the luggage compartment, pull the knob with
the gas pump symbol on the right side panel.
Observe the following when refueling
When handling fuels, follow the safety
precautions posted at the filling station. Otherwise, there is a danger of personal injury
and property damage.<
Place the fuel filler cap in the bracket attached
to the fuel filler door.
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid raising the filler
nozzle during refueling, otherwise this
>results in premature pump shutoff
>can lead to reduced efficiency in the fuel-
vapor recovery system
The fuel tank is full when the filler nozzle clicks
off the first time.
Fuel tank capacity
Approx. 18.5 US gal/70 liters, including the
reserve capacity of approx. 2.6 US gal/10 liters.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, otherwise engine functions are not
ensured and damage can occur.<
Fuel filler cap
Closing
Insert the cap and turn it clockwise until there is
a clearly audible click.
Do not crush the band attached to the
cap; otherwise, the cap may not properly
seal and fuel vapors can escape.<
A message
* is displayed if the cap is loose or
missing.

Fuel specifications
Never used leaded gasoline; it will perma-
nently damage the catalytic converter.
Do not use E85, i.e. fuel that consists of 85%
ethanol, or Flex Fuel. Otherwise permanent
damage to the engine and the fuel supply sys-
tem will result.<
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI rating is 87.
If you use gasoline with this minimum AKI rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no affect on the engine life.
Do not use gasoline below the specified
minimum quality, otherwise engine dam-
age can result.<
Use high-quality brands
Field experience has demonstrated significant
differences in fuel quality: volatility, composi-
tion, additives, etc., among gasolines offered for
sale in the United States and Canada. Fuels
containing up to and including 10 % ethanol or
other oxygenates with up to 2.8 % oxygen by
weight, that is, 15 % MTBE or 3 % methanol
plus an equivalent amount of co-solvent, will
not void the applicable warranties with respect
to defects in materials or workmanship.
The use of poor-quality fuels may result in
problems relating to drivability and start-
ing, and to a tendency to stall, especially under
certain environmental conditions such as high
ambient temperature and high altitude.
Should you encounter drivability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in unscheduled maintenance.<

Recommended tire brands
Certain tire makes are recommended by BMW
depending on the tire size. You can recognize
these from the clearly visible BMW marking on
the tire sidewall.
When used properly, these tires comply with
the most demanding standards for safety and
vehicle response.
Run-flat tires
When mounting new tires, or changing from
summer to winter tires or vice versa, use run-flat
tires for your own safety. In addition, no spare
tire is available in case of a flat tire. Your BMW
center will be glad to advise you.
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Watch speed
Always observe the maximum permissi-
ble speed for the winter tires, otherwise
tire damage may occur, which can result in acci-
dents.<
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible. Always
protect tires against all contact with oil, grease
and fuels. Do not exceed the maximum tire
inflation pressure indicated on the side wall of
the tire.
Rotating wheels between axles
BMW does not recommend moving the front
wheels to the rear or vice versa, as otherwise
the handling characteristics may be impaired.
With tires of different makes and types
* such a
change is not permissible.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Consult your BMW center for more infor-
mation.
These snow chains are approved exclusively for
use in pairs on the rear wheels with the tire size:
>245/50 R 17
>245/45 R 18
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with the chains mounted.
Do not initialize the Flat Tire Monitor after
installing snow chains as this could cause
the Flat Tire Monitor to malfunction.
When driving with snow chains, it may be prac-
tical to briefly activate DTC, refer to page89.<

Socket for OBD Onboard
Diagnostics interface
Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located under a cover on the left
side of the driver's footwell, directly under the
instrument panel.
Exhaust-gas values
The warning lamp lights up. The
exhaust-gas values worsen. Have the
vehicle checked as soon as possible.
Display of the previously described
malfunction on Canadian models.
The lamp flashes under certain condi-
tions. This is a sign of excessive misfiring of the
engine. In this case you should reduce speed
and drive to the nearest BMW center as soon as
possible. Heavy engine misfiring causes seri-
ous damage to the emission-relevant compo-
nents, especially the catalytic converter, within
a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system can detect the
escape of fuel vapor. Then a display lights up. If
the cap is then tightened, the display will go out
within a few days.<
Event Data Recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with
a device for recording or transmitting certain
v e hi c l e d a t a o r i n f o r m a t i o n . I f y o u h a v e a l s o s u b -
scribed to BMW Assist, certain vehicle data can be transmitted or recorded to enable corre-
sponding services.

Care
228 can result in water penetration. Follow the oper-
ating instructions for the high-pressure clean-
ing jets.<
When using high-pressure cleaning jets,
do not remain in one place for a long time
and be sure to maintain a distance of at least
12 in/30 cm from sensors, e.g. Park Distance
Control sensors or radar sensors.<
Hand washing
When washing the vehicle by hand, use plenty
of water and car washing shampoo. Clean the
vehicle with gentle pressure using a sponge or a
washing brush.
Before cleaning the windshield, deacti-
vate the rain sensor or switch off the igni-
tion to prevent unwanted wiper operation.<
Follow local guidelines for washing vehi-
cles by hand.<
Headlamps
Do not rub dry and never use abrasives or
strong solvents to clean the covers.
Loosen dirt, e.g. insects, with shampoo or
insect remover and wash away with plenty of
water.
Use a window de-icer to remove accumulated
ice and snow, not a scraper.
Windows
Use a glass cleaner to clean the inside and out-
side surfaces of the windows and the glass sur-
faces of the mirrors.
Do not use quartz-containing cleansers
to clean glass surfaces of the mirrors.<
Wiper blades
Clean with soapy water and replace regularly to
prevent streaking.
The presence of wax and sealant residues
and dirt on the windows leads to streaking
during wiper operation and results in premature
wear on wiper blades as well as interference
with the rain sensor.<
Convertible top care
The appearance and service life of the convert-
ible top depend on proper care and operation.
Please follow these instructions:
>Never stow the convertible top in the con-
vertible top compartment when it is wet or
frozen, since this can cause water marks,
mildew stains, and scuff marks.
>Remove water marks on the headliner with
a microfiber cloth and interior cleanser.
>When parking for long intervals in enclosed
spaces, make sure there is sufficient venti-
lation.
>Remove bird droppings immediately
because their caustic properties have a cor-
rosive effect on the convertible top and can
damage the rubber seals.
Do not use stain remover, paint thinner,
solvents, gasoline, or the like to remove
stains. These substances can damage the rub-
ber coating. Improper care and cleaning can
cause leaks to develop in the convertible top
and its seams.<
In the event of more serious soiling, use a spe-
cial convertible top cleaner.
When doing so, follow the manufacturer's
directions for use.
After three to five washings, treat the convert-
ible top with sealant.
Caring for the vehicle finish
Regular care helps your vehicle retain its value
and protects the paint from the long-term
effects of aggressive substances.
Regionally occurring environmental factors can
affect and damage vehicle finish. It is therefore
important to tailor the frequency and extent of
your car care accordingly.
Immediately remove particularly aggressive
substances such as spilled fuel, oil, grease,
brake fluid, tree resin, or bird droppings; other-
wise, they may damage your paint.
