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 at which the
TPMS low tire pressure telltale illuminates.
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 lit. This sequence will continue
upon subsequent vehicle startups as long as
the malfunction exists. When the malfunction
indicator is illuminated, 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
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Active steering*
The concept
Active steering varies the turning angle of the
front wheels in relation to steering wheel move-
ments. It also varies the steering force required
to turn the wheels depending on the speed at
which you are driving.
When you are driving in the low road speed
range, e.g. in a town or when parking, the steer-
ing angle is increased, i.e. steering becomes
very direct and less effort is required to turn the
wheels. In the higher speed range, on the other
hand, the steering angle is reduced as the
speed increases. This improves the handling of
your BMW over the entire speed range.

Things to remember when driving
126
Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follow the instructions below
in order to achieve the optimal service life and
economy of operation for your vehicle.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do
not exceed an engine speed of 4,500 rpm or a
road speed of 100 mph/160 km/h.
Avoid full-throttle operation and use of the
transmission's kickdown mode.
After driving 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
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 cautiously 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 cautiously during this break-in
period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
Saving fuel
The fuel consumption of your vehicle depends
on several factors. You can lower fuel consump-
tion and the environmental impact by taking
certain measures, adjusting your driving style
and having the vehicle serviced regularly.
Remove any unneeded cargo
Additional weight increases fuel consumption.
Remove any mounted parts after you
have finished using them
Remove unneeded additional mirrors, the roof
rack and the rear luggage rack after use.
Mounted parts affect the vehicle's aerodynam-
ics and increase fuel consumption.
Close the windows and glass roof
An open glass roof or window causes higher air
resistance and thus increases fuel consump-
tion.
Check tire inflation pressure regularly
Check the tire inflation pressure at least twice a
month and before embarking on a long journey,
and correct it if necessary.
Low tire inflation pressure causes higher rolling
resistance and thus increases fuel consumption
and tire wear.
Set off immediately
Do not let the engine warm up while the car is
still standing, but set off immediately at moder-
ate engine speed. This is the fastest way for the
cold engine to reach its operating temperature.

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 driving on
winter roads or at temperatures below +45 7/
+7 6. 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.
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 tires, 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 against 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 this could impair driving
characteristics. If the tires are of mixed sizes,
swapping wheels between the axles is not per-
missible.
Snow chains*
Only certain fine-link snow 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
page90.<

Care
230
Sports automatic transmission with
double 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 into the ignition
lock, even with Comfort Access.
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.
The transmission is switched into position P:
>automatically after approx. 30 minutes
>if you remove the infrared remote control
from the 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 1407/606.
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 sensors and cam-
eras, e.g. of the Park Distance Control or Rear
View Camera, for an extended period and main-
tain a distance of at least 1 ft/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 unintentional 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.
Loosen dirt, e.g. insects, with shampoo or
insect remover and wash away with copious
quantities of water.
Thaw ice with a windshield deicer 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.<
Convertible: retractable hardtop
Proceed as you would in a normal car wash.
When you open a wet hardtop, water
drops may run into the cargo area. If nec-
essary, remove items from the cargo area
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 paint-
work.
Repairing paintwork damage
Immediately repair scratches or similar
damage, such as that caused by stones
hitting the vehicle, where necessary to prevent
rusting.<
BMW recommends having paintwork damage
repaired by a professional paint repair work-
shop according to BMW specifications using
original BMW paint materials.
