2012 BMW 640I COUPE engine overheat

▷When opening and closing the driver door, if
the driver's seat belt is unbuckled and the
low beams are switched off.▷While the driver's seat belt is unbuckled, if
the driver's door is open and the low beams
are switched off.
When the ignition is switched off, by opening or
closing the driver's door or unbuckling the driv‐
er's seat belt, the radio ready state remains ac‐
tive.
Radio ready state
Activate radio ready state:
▷When the ignition is switched off: press ON/
OFF button on the radio.▷When the engine is running: press START/
STOP button.
Some electronic systems/power consumers re‐
main ready for operation.
Radio ready state switches off automatically:
▷After approx. 8 minutes.▷When the vehicle is locked using the central
locking system.▷Shortly before the battery is discharged
completely, so that the engine can still be
started.
Starting the engine
General information Enclosed areas
Do not let the engine run in enclosed
areas; otherwise, breathing of exhaust fumes
may lead to loss of consciousness and death.
The exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀
Unattended vehicle
Do not leave the car unattended with the
engine running; otherwise, it presents a poten‐
tial source of danger.
Before leaving the car with the engine running,
set the parking brake and place the transmission
in position P or neutral to prevent the car from
moving.◀
Frequent starting in quick succession
Avoid repeated futile attempts at starting
the car and avoid starting the car frequently in
quick succession. Otherwise, the fuel is not
burned or is inadequately burned, and there is
the danger of overheating and damaging the
catalytic converter.◀
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving at mod‐
erate engine speeds.
Manual transmission
Starting the engine1.Depress the brake pedal.2.Press on the clutch and shift to neutral.3.Press the Start/Stop button.
The ignition is activated automatically for a cer‐
tain time and is stopped as soon as the engine
starts.
Automatic-Transmission

Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved for
the vehicle and can be properly fixed in place.
Ensure that the floor mats are securely fastened
again after they were removed for cleaning, for
example.◀
Driving in wet conditions
When roads are wet or there is heavy rain, briefly
exert gentle pressure on the brake pedal every
few miles.
Ensure that this action does not endanger other
road users.
The heat generated in this process helps dry the
brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills
Drive long or steep downhill gradients in the gear
in which the least braking is required. Otherwise,
the brake system may overheat, resulting in a
reduction in the brake system efficiency.
Manual transmission:
You can increase the engine's braking effect by
shifting down, going all the way to first gear, if
necessary.
Automatic transmission:
You can increase the engine's braking effect by
shifting down in the manual mode of the auto‐
matic transmission, refer to page 66.
Avoid load on the brakes
Avoid placing excessive load on the brake
system. Light but consistent brake pressure can
lead to high temperatures, brake wear and pos‐
sibly even brake failure.◀Do not drive in neutral
Do not drive in neutral or with the engine
stopped, as doing so disables engine braking. In
addition, steering and brake assist is unavailable
with the engine stopped.◀
Brake disc corrosion
Corrosion on the brake discs and contamination
on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected.
Condensation under the parked vehicle
When using the automatic climate control, con‐
densation water develops that exits underneath
the vehicle.
Therefore, traces of condensed water under the
vehicle are normal.
