2.
In the event of complete pressure loss,
0 psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guidelines:
>With a light load:
1 person without luggage:
approx. 155 miles/250 km
> With a medium load:
1 person, cargo bay full, or 2 people
without luggage:
approx. 95 miles/150 km
> With a full load:
2 people, cargo bay full:
approx. 30 miles/50 km
Drive cautiously 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 vibration or lo ud noises occur during
the journey, this may be an indication that the
damaged tire has finally failed. Reduce your
speed and pull over as soon as possible at a
suitable location. Otherw ise parts of the tire
could come loose, resulting in an accident. Do
not continue driving. Instead, contact your
BMW center. <
Message for unsuccessful system
reset
The warning lamp lights up yellow. A
message will appear on the Control
Display. The system is not reset after
a tire has been changed, for example.
Check the tire inflation pressure and reset the
system, refer to page 83.

Malfunction
The small warning lamp flashes in
yellow and then lights up continu-
ously; the larger warning lamp comes
on in yellow. On the Control Display,
the tires are shown in gray and a message
appears. No punctures can be detected.
This type of message is shown in the following
situations:

other systems or devices using 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 infl ation 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, yo u 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 under-inflated. 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 underi nflated tire causes the
tire to overheat and ca n 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 dr iver’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.

Things to remember when driving
110
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.
Do not drive with full-throttle operation, and do
not use the transmission 's kick-down mode or
Launch Control.
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 no t achieve their full trac-
tion potential until afte r 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 clut ch reaches its optimal
level only after a distan ce 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 renewe d 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 incr eases fuel consumption.
Remove any mounted parts after you
have finished using them
Remove additional mirrors and the luggage rack
when they are no longer in use. Mounted parts
affect the vehicle's aerodynamics and increase
fuel consumption.
Close both windows
An open glass roof or window causes higher air
resistance and thus increases fuel con-
sumption.
Check tire inflation pressure regularly
Check the tire inflation pr essure 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 wa rm 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.

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.<

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:
> Automatically after approx. 30 minutes
> When you take the remo te control out of 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 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.
