2012 BMW 550I XDRIVE GRAN TURISMO flat tire

Do this by checking the air pressure in all
four tires.
If the tire inflation pressure in all four tires is
correct, the Flat Tire Monitor may not have
been initialized. In this case, initialize the
system.
If an identification is not possible, please
contact the service center.2.Rectify the flat tire.
Run-flat tires
Maximum speed
You can continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
Continued driving with a flat tire
If continuing to drive with a damaged tire:
1.Avoid sudden braking and steering maneu‐
vers.2.Do not exceed a speed of 50 mph/80 km/h.3.Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four tires is
correct, the Flat Tire Monitor may not have
been initialized. In this case, initialize the
system.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
For a vehicle containing an average load, the
possible driving distance is approx. 50 miles/
80 km.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing over obstacles, e.g., curbs, potholes, etc.
Because the possible driving distance depends
on how the vehicle is used during the trip, the
actual distance may be smaller or greater de‐
pending on the driving speed, road conditions,
external temperature, cargo load, etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering prop‐
erties.◀
Final tire failure
Vibrations or loud noises while driving can
indicate the final failure of the tire. Reduce speed
and stop; otherwise, pieces of the tire could
come loose and cause an accident. Do not con‐
tinue driving, and contact your service center. ◀
Lane departure warning
The concept
This system issues a warning at speeds above
approx. 40 mph/65 km/h if the vehicle is about
to leave the lane on roads with lane markings.
The steering wheel begins vibrating gently. The
time of the warning may vary depending on the
current driving situation.
The system does not provide a warning if the
turn signal is set before leaving the lane.

LoadingVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
General information Overloading the vehicle
To avoid exceeding the approved carrying
capacity of the tires, never overload the vehicle.
Overloading can lead to overheating and in‐
creases the rate at which damage develops in‐
side the tires. This could result in a sudden loss
of tire inflation pressure.◀
No fluids in the trunk
Make sure that fluids do not leak into the
trunk; otherwise, the vehicle may be damaged. ◀
Determining the load limit1.Locate the following statement on your ve‐
hicle’s placard:▷The combined weight of occupants and
cargo should never exceed XXX kg or
YYY lbs. Otherwise, damage to the ve‐hicle and unstable driving situations may
result.2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.3.Subtract the combined weight of the driver
and passengers from XXX kilograms or YYY
pounds.4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals
1,000 lbs and there will be four 150 lbs pas‐
sengers in your vehicle, the amount of avail‐
able cargo and luggage load capacity is
400 lbs: 1,000 lbs minus 600 lbs = 400 lbs.5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in Step 4.
Load
The maximum load is the sum of the weight of
the occupants and the cargo.
The greater the weight of the occupants, the
less cargo that can be transported.

Saving fuelVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
General information
Your vehicle contains advanced technology for
the reduction of fuel consumption and emis‐
sions.
Fuel consumption depends on a number of dif‐
ferent factors.
The implementation of certain measures, driv‐
ing style and regular maintenance can have an
influence on fuel consumption and on the envi‐
ronmental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts
following use
Remove auxiliary mirrors, roof or rear luggage
racks which are no longer required following
use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.Close the windows and glass
sunroof
Driving with the glass sunroof and windows
open results in increased air resistance and
raises fuel consumption.
Check the tire inflation
pressure regularly
Check and, if necessary, correct the tire inflation
pressure at least twice a month and before start‐
ing on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away without delay
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.
This is the fastest way for the cold engine to
reach its operating temperature.
Look well ahead when driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehicle
driving ahead of you.
Driving smoothly and looking ahead reduces
fuel consumption.
Use coasting conditions
When approaching a red light, take your foot off
the accelerator and let the vehicle coast to a halt.
On a downhill gradient, take your foot off the ac‐
celerator and let the vehicle roll.Seite 164Driving tipsSaving fuel164

Wheels and tiresVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐

Tire inflation pressure
Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:▷The service life of the tires.▷Road safety.▷Driving comfort.
Checking the pressure
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been parked for at least 2 hours. When the tires
are warm, the tire inflation pressure is higher.
Check the tire inflation pressure regularly
Regularly check the tire inflation pressure
and correct it as needed: at least twice a month
and before a long trip. If you fail to observe this
precaution, you may be driving on tires with in‐
correct tire pressures, a condition that may not
only compromise your vehicle's driving stability,
but also lead to tire damage and the risk of an
accident.◀
After correcting the tire inflation pressure:
▷Reinitialize the Flat Tire Monitor.▷Reinitialize the Tire Pressure Monitor.Pressure specifications
The tire inflation pressure table, refer to
page 262, contains all pressure specifications
for the specified tire sizes at the ambient tem‐
perature. Pressure specifications apply to ap‐
proved tire sizes and recommended tire brands.
This information can be obtained from your
service center.
To identify the correct tire inflation pressure,
please note the following:▷Tire sizes of your vehicle.▷Maximum allowable driving speed.
Tire inflation pressures up to 100 mph/
160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure val‐
ues in the tire inflation pressure table, refer to
page 262, and adjust as necessary.
These pressure values can also be found on the
tire inflation pressure label on the driver's door
pillar.
Maximum permissible speed
Do not exceed 100 mph/160 km/h; other‐
wise, tire damage and accidents may result.◀

Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
Those grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test surfa‐
ces of asphalt and concrete. A tire marked C may
have poor traction performance.
The traction grade assigned to this tire is based
on straight-ahead braking traction tests, and
does not include acceleration, cornering, hydro‐
planing, or peak traction characteristics.
Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel. Sus‐
tained high temperature can cause the material
of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of
performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety
Standard No. 109. Grades Band A represent
higher levels of performance on the laboratory
test wheel than the minimum required by law.
Temperature grade for this tire
The temperature grade for this tire is es‐
tablished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately or in
combination, can cause heat buildup and pos‐
sible tire failure.
If necessary, have the vehicle towed.◀
RSC – Run-flat tires
Run-flat tires, refer to page 269, are labeled with
a circular symbol containing the letters RSC
marked on the sidewall.M+S
Winter and all-season tires with better cold
weather performance than summer tires.
Tire tread
Summer tires
Do not drive with a tire tread depth of less than
0.12 in/3 mm.
There is an increased danger of hydroplaning if
the tread depth is less than 0.12 in/3 mm.
Winter tires
Do not drive with a tire tread depth of less than
0.16 in/4 mm.
Below a tread depth of 0.16 in/4 mm, tires are
less suitable for winter operation.
Minimum tread depth
Wear indicators are distributed around the tire's
circumference and have the legally required
minimum height of 0.063 in/1.6 mm.
They are marked on the side of the tire with TWI,
Tread Wear Indicator.
Tire damage
General information
Inspect your tires often for damage, foreign ob‐
jects lodged in the tread, and tread wear.
