fuel pressure BMW 750I XDRIVE 2012 F01 Owner's Manual

or more of your tires is significantly under-in‐
flated. 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
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stopping
ability. Please note that the TPMS is not a sub‐
stitute for proper tire maintenance, and it is the
driver's responsibility to maintain correct tire
pressure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low
tire pressure telltale. Your vehicle has also been
equipped with a TPMS malfunction indicator to
indicate when the system is not operating prop‐
erly. The TPMS malfunction indicator is com‐
bined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will
flash for approximately one minute and then re‐
main continuously illuminated. This sequence
will continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the mal‐
function 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 re‐
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
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 system does not provide a warning if the
turn signal is set before leaving the lane. Switching on/off
Press the button.
▷ On: the LED lights up.
▷ Off: the LED goes out.
The system can issue warnings at speeds above
approx. 40 mph/65 km/h.
The state is stored for the remote control cur‐
rently in use.
Display ▷
Lines, arrow 1: the system is activated.
▷ Arrows, arrow 2: at least one lane marking
was detected and warnings can be issued.
Issued warning
If you leave the lane and if a lane marking has
been detected, the steering wheel begins vi‐
brating.
If

the turn signal is set before changing the lane,
a warning is not issued.
End of warning
The warning ends:
▷ Automatically after approx. 3 seconds.
▷ When returning to your own lane. Seite 94

Safety

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.
The flow of fuel is interrupted while coasting.
Switch off the engine during longer
stops
Switch off the engine during longer stops, e.g.,
at traffic lights, railroad crossings or in traffic
congestion.
Fuel savings are achieved after the vehicle is
switched off for only approx. 4 seconds. Switch off any functions that are not
currently needed
Functions
such as seat heating and the rear win‐
dow defroster require a lot of energy and con‐
sume additional fuel, especially in city and stop-
and-go traffic.
Therefore, switch off these functions if they are
not actually needed.
Have maintenance carried out
Have vehicles maintained regularly to achieve
optimal vehicle economy and operating life.
Have the maintenance carried out by your serv‐
ice center.
Please also note the BMW Maintenance Sys‐
tem.

Retreaded tires
Possibly substantial variations in the de‐
sign and age of the tire casing structures can
limit service life and have a negative impact on
road safety.◀
Winter tires
The manufacturer of your vehicle recommends
winter tires for winter roads or at temperatures
below +45 ℉/+7 ℃.
Although
so-called all-season M+S tires do pro‐
vide better winter traction than summer tires,
they do not provide the same level of perform‐
ance as winter tires.
Maximum speed of winter tires
If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then display a corresponding sign in the field of
vision. You can obtain this sign from the tire spe‐
cialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for the
winter tires; otherwise, tire damage and acci‐
dents can occur.◀
Run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire. Your
service center will be glad to advise you.
Rotating wheels between axles
The manufacturer of your vehicle advises
against swapping wheels between the front and
rear axles.
This can impair the handling characteristics.
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 pres‐
sure indicated on the side wall of the tire. Run-flat tires*
Label
RSC label on the tire sidewall.
The wheels are composed of special rims and
tires that are self-supporting, to a limited de‐
gree.
The

support of the sidewall allows the tire to re‐
main drivable to a restricted degree in the event
of a pressure loss.
Continued driving with a damaged tire., refer to
page 93
Changing run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire. Your
service center will be glad to advise you.
Snow chains
Fine-link snow chains
Only certain types of fine-link snow chains have
been tested by the manufacturer of your vehicle,
classified as road-safe and recommended.
Consult your service center for more informa‐
tion.
Use
Use only in pairs on the rear wheels, equipped
with the tires of the following size:
▷ 245/50 R 18.
▷ 245/45 R 19.
Follow the chain manufacturer's instructions.
