2015 BMW I8 fuel pressure

▷Inflation was not carried out according to
specifications.▷The tire inflation pressure has fallen below
the level of the last confirmation.
In this case:
▷Check the tire pressure and correct as
needed.▷Carry out a reset of the system after a tire
change.
System limits
The system does not function properly if a re‐
set has not been carried out, e.g., a flat tire is
reported though tire inflation pressures are
correct.
The tire inflation pressure depends on the
tire's temperature. Driving or exposure to the
sun will increase the tire's temperature, thus
increasing the tire inflation pressure. The tire
inflation pressure is reduced when the tire
temperature falls again. These circumstances
may cause a warning when temperatures fall
very sharply.
Malfunction The yellow warning lamp flashes and
then lights up continuously. A Check
Control message is displayed. No flat
tire or loss of tire inflation pressure can be de‐
tected.
Display in the following situations:
▷A wheel without TPM electronics is fitted:
have the service center check it if needed.▷Malfunction: have the system checked by
your service center.▷TPM was unable to complete the reset.
Reset the system again.▷Interference through systems or devices
with the same radio frequency: after leav‐
ing the area of the interference, the system
automatically becomes active again.Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
System
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended
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 inflation
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
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly 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 pres‐
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel ef‐
ficiency and tire tread life, and may affect the
vehicle's handling and stopping ability. Please
note that the TPMS is not a substitute 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 indi‐
cator to indicate when the system is not oper‐
ating properly. The TPMS malfunction indica‐
tor is combined with the low tire pressure
telltale. When the system detects a malfunc‐
tion, the telltale will flash for approximately one
minute and then remain continuously illumi‐
nated. This sequence will continue upon sub‐
sequent vehicle start-ups as long as the mal‐
function 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 replace‐
ment or alternate tires or wheels on the vehicleSeite 101SafetyControls101

Increase rangeGeneral informationThe vehicle contains comprehensive technolo‐
gies for reducing the energy consumption and
for maximizing the range.
The range depends on a number of different
factors.
The implementation of certain measures, driv‐
ing style and regular maintenance can increase
range and thereby also reduce the environ‐
mental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts
following use
Attached parts on the vehicle impair the aero‐
dynamics and increase the energy consump‐
tion.
Closing the windows
Open windows increase air resistance and
therefore lead to greater fuel consumption.
Tires General information Tires can affect energy consumption in various
ways, for instance energy consumption can be
influenced by tire size.Check the tire inflation pressure
regularly
Check and, if needed, correct the tire inflationpressure at least twice a month and before
starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises energy consumption
and tire wear.
Standing air conditioning Run advance climate control, refer to
page 127, in the vehicle during charging if pos‐
sible before driving off.
Heating and cooling operations are very en‐
ergy intensive and substantially reduce the
electric range.
Look well ahead when
driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐
cle driving ahead of you.
Driving smoothly and proactively reduces fuel
consumption.
Longer braking procedures result in more effi‐
cient charging of the high-voltage battery via
energy recovery from braking.
Use coasting
When approaching a red light, take your foot
off the accelerator and let the vehicle coast to
a halt.Seite 144Driving tipsIncrease range144

RefuelingVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Hints Observe the fuel recommendation, refer to
page 161, prior to refueling.
Refuel promptly
Refuel no later than at a range of
30 miles/50 km or engine operation might fail
and damage might occur.◀
To also ensure all engine functions under un‐
favorable conditions, e.g. steep vehicle inclina‐
tions, at least 2.6 US gal/10 liters fuel should
be refueled.
Do not refuel unless the engine is at a
standstill and the selector lever is in posi‐
tion P/N
Do not refuel unless the engine is at a standstill
and the selector lever is in position P/N, other‐
wise the buildup of pressure may cause the
fuel nozzle to shut off prematurely.◀
Tank vent
The concept The vehicle is equipped with a special fuel
tank. It is designed for special requirements
that arise with the hybrid operation of the vehi‐cle, e.g., alternating drive with combustion en‐
gine or electric motor.
General information In the fuel tank, excess pressure can build up
due to gasoline vapors which are dissipated
before the tank lid is opened.
Overview The button is located on the driver's side on
the door armrest.
Tank venting1.Switch off drive readiness.2.
Press button to start the pressure
equalization.
The status of the tank venting is displayed
in the instrument cluster. In rare cases, the
tank venting can last several minutes.
If the tank venting has been completed, a
message is displayed in the instrument
cluster. The tank lid is released for open‐
ing.
3.Open the fuel filler flap.
If the fuel filler flap is not opened within 10
minutes after the fuel filler flap was re‐
leased, the fuel filler flap relocks. Press
button again.

properly and fuel vapors can escape.◀
Manually unlocking fuel filler flap
In the event of an electrical malfunction, e.g.
The release is located in the trunk.1.Open the cover on the right side trim.2.Pull the green knob with the fuel pump
symbol. This releases the fuel filler flap.3.Open the fuel filler flap.4.Carefully open the fuel filler flap. Excess
pressure can build up in the fuel tank from
gasoline vapor.5.Fuel the vehicle as usual. This may be diffi‐
cult due to the residue pressure in the
tank, caused by frequent stopping of the
fuel pump nozzle, e.g.Seite 159RefuelingMobility159

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
Winter tires are recommended for operating on
winter roads.
Although so-called all-season M+S tires 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 a respective symbol is displayed in your
field of vision. You can obtain this sign from the
tire specialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for
the respective winter tires; otherwise, tire dam‐
age and accidents can occur.◀
Rotating wheels between axles Different wear patterns can occur on the front
and rear axles depending on individual driving
conditions. The tires can be rotated between
the axles to achieve even wear. Your service
center will be glad to advise you. After rotating,
check the tire pressure and correct if needed.
Rotating the tires is not permissible on vehi‐
cles with different tire sizes or rim sizes on the
front and rear axles.
StorageStore 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.Mobility System
The concept
With the Mobility System, minor tire damage
can be sealed quickly to enable continued
travel. To accomplish this, sealant is pumped
into the tires, which seals the damage from the
inside.
The compressor can be used to check the tire
inflation pressure.
Hints▷Follow the instructions on using the Mobi‐
lity System found on the compressor and
sealant container.▷Use of the Mobility System may be ineffec‐
tive if the tire puncture measures approx.
1/8 in/4 mm or more.▷Contact the nearest service center if the
tire cannot be made drivable.▷If possible, do not remove foreign bodies
that have penetrated the tire.▷Pull the speed limit sticker off the sealant
container and apply it to the steering
wheel.▷The use of a sealant can damage the TPM
wheel electronics. In this case, have the
electronics checked at the next opportu‐
nity and have them replaced if needed.
Enclosed areas
Do not let the engine run in enclosed
areas, since breathing in exhaust fumes may
lead to loss of consciousness and death. The
exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀
Storage The Mobility System is located behind the left
side trim in the trunk.
