2015 BMW I8 engine overheat

Lighting lights up steady blue
After drive readiness is switched on, light turns
blue. The vehicle is ready to drive. The READY
indicator lights up in the instrument cluster. In
addition, a signal sounds.
Lighting off
Drive readiness, operating readiness and
radio-ready state are turned off. The vehicle is
in the idle state. The charging cable may be
connected.
Activating drive readiness1.Close the driver's door.2.Depress the brake pedal.3.Press the Start/Stop button.
Drive readiness is active, electric driving, Silent
Start or Start of the combustion engine.
Electric drive readiness, Silent Start
The vehicle is ready for driving without starting
the combustion engine.
Silent Start is possible if the requirements for
Electric driving, refer to page 64, are met.
Display READY indicates drive readi‐
ness.
Starting the combustion engine 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.◀
Unattended vehicle
Do not leave the vehicle unattended with
engine running or drive readiness switched on;
otherwise, it may pose a risk.
Before leaving the vehicle, engage lever in po‐
sition P P, and set the parking brake; other‐
wise, the vehicle is not secured against rolling
away.◀
Repeated starting in quick succession
Avoid trying to start the vehicle repeat‐
edly and in quick succession. Otherwise, the
fuel is not burned or is inadequately burned,
posing a risk of overheating and damage to the
catalytic converter.◀
The combustion engine is started with Acti‐
vate drive, refer to page 63, readiness under
the following conditions:▷The temperature of the hybrid system is
too high.▷The charge level or temperature of the
high-voltage battery is too low.
Driving away
1.Activate drive readiness.2.Apply the brake and engage lever in posi‐
tion P D, SPORT or R.3.Release the parking brake.4.Drive away.
Deactivating drive readiness
After parking the vehicle, you may hear noises due to operation of the hybrid system, such as
for cooling of the high-voltage battery.
After stopping the vehicle:
1.Depress the brake pedal.2.Set the parking brake.3.Press the Start/Stop button.
The READY indicator goes out and a signal
sounds. In case of longer idle times, follow the
instructions in the Care chapter, refer to
page 190.

Only use floor mats that have been approved
for the vehicle and can be properly attached to
floor.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, e.g.◀
Driving in wet conditions When roads are wet, salted, or in heavy rain,
press brake pedal ever so gently every few
miles.
Ensure that this action does not endanger other traffic.
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 Avoid stressing the brakes
Avoid placing excessive stress on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brakes
wearing out and possibly even brake failure.◀
Do not drive in neutral
Do not drive in neutral, in the ECO PRO
driving program, or with drive readiness
switched off, as doing so disables engine brak‐
ing. In addition, steering and brake assist are
unavailable with the engine stopped.◀
Drive long or steep downhill gradients in the
gear that requires least braking efforts. Other‐
wise the brakes may overheat and reduce
brake efficiency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if needed.
On downhill sections, use energy recovery if
possible to decelerate the vehicle.Brake disc corrosion
Brake disc corrosion and contamination of the
brake pads are favored by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion will built up when the maximum
pressure applied to the brake pads during
braking is not reached - thus discs don't get
cleaned.
Corrosion buildup on the brake discs will cause
a pulsating effect on the brakes in their re‐
sponse - generally that cannot be corrected.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops collecting under‐
neath the vehicle.
These traces of water under the vehicle are
normal.
