2014 BMW 4 SERIES COUPE Air con low pressure

Actions in the event of a flat tire
Normal tires1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
If the tire inflation pressure in all four tires
is shown to be correct, it is possible that
the Tire Pressure Monitor did not perform
a reset. Then perform the reset.
If an identification is not possible, please
contact the service center.2.Fixing a flat tire, where applicable with the
Mobility System.
Run-flat tires
Maximum speed
You may 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 shown to be correct, it is possible that
the Tire Pressure Monitor did not perform
a reset. In that case, carry out a reset.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on cargo load, driv‐
ing style and road conditions.
A vehicle with an average load has a possible
driving range of approx. 50 miles/80 km.
A vehicle with a damaged tire reacts differ‐
ently, e.g., it has reduced lane stability during
braking, a longer braking distance and different
self-steering properties. Adjust your driving
style accordingly. Avoid abrupt steering ma‐
neuvers or driving over obstacles, e.g., curbs,
potholes, etc.
Because the possible driving distance de‐
pends on how the vehicle is used during the
trip, the actual distance may be shorter or lon‐
ger depending on the driving speed, road con‐
ditions, 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.
Your car handles differently when you lose tire
inflation pressure, e.g., your lane stability is re‐
duced when braking, braking distances are
longer and the self-steering properties will
change.◀
Final tire failure
Vibrations or loud noises while driving
can indicate the final failure of a tire. Reduce
speed and stop; otherwise, pieces of the tire
could come loose and cause an accident. Do
not continue driving and contact your service
center.◀
Required tire inflation pressure check
message
A Check Control message is displayed in the
following situations▷The system has detected a wheel change,
but no reset was done.▷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.Seite 101SafetyControls101

Saving fuelVehicle features and optionsThis 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.
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.
Carrying out certain measures, such as a mod‐
erate driving style and regular maintenance,
can influence fuel consumption and the envi‐
ronmental impact.
Remove unnecessary cargoAdditional 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
thereby reduces the range.
Tires
General information Tires can affect fuel consumption in various
ways, e.g., tire size may influence fuel con‐
sumption.
Check the tire inflation pressure
regularly
Check and, if needed, correct the tire inflation
pressure at least twice a month and before
starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away immediately
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 quickest way of warming the cold
engine up to operating temperature.
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.Seite 172Driving tipsSaving fuel172

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 the
vehicle, classified as road-safe and approved.
Information about the approved snow chains
are available from the service center.
Use
Use only in pairs on the rear wheels, equipped
with the tires of the following size:▷225/50 R 17.▷225/45 R 18.
Follow the snow chain manufacturer's instruc‐
tions.
Make sure that the snow chains are always
sufficiently tight. Retighten as needed accord‐
ing to the chain manufacturer's instructions.
Do not initialize the Flat Tire Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
Do not initialize the Tire Pressure Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
When driving with snow chains, briefly activate
Dynamic Traction Control if needed.
Maximum speed with snow chains Do not exceed a speed of 30 mph/50 km/hwhen using snow chains.
