2015 BMW 3 SERIES ACTIVE HYBRID engine overheat

DisplayREADY 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
the engine running; doing so poses a risk of
danger.
Before leaving the vehicle with the engine run‐
ning, set the parking brake and place the trans‐
mission in selector lever position P or N to pre‐
vent the vehicle from moving.◀
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 69, readiness under
the following conditions:▷The drive system is not at operating tem‐
perature.▷The temperature of the hybrid system is
too high.▷The high-voltage battery has an insuffi‐
cient charge.
Driving away
1.Activate drive readiness.2.Engage selector lever position D, M/S or R.3.Release the parking brake.4.Drive away.
Deactivating drive readiness
After stopping the vehicle:
1.Engage selector lever position P.2.Press the Start/Stop button.3.Set the parking brake.
After parking the vehicle, you may hear noises
due to operation of the hybrid system, such as
for cooling of the high-voltage battery.
Before driving into a car wash So that the vehicle can roll into a car wash ob‐
serve instructions for going into an automatic
car wash, refer to page 228.
Auto Start/Stop function
The concept The Auto Start/Stop function helps save fuel.
The system switches off the combustion en‐
gine when conditions for electric driving have
been met. The ignition or drive readiness re‐
mains switched on.
READY appears on the tachometer. If neces‐
sary, the combustion engine starts automati‐
cally.
The combustion engine is also stopped during
the trip when rolling out or braking. This driving
condition, in which the vehicle is travelling
without power and energy recovery is not ac‐
tive, is referred to as coasting, refer to
page 71.
Note The combustion engine is not switched off au‐
tomatically in the following situations:
▷The combustion engine is not at operating
temperature.Seite 70ControlsDriving70

Driving through waterObserve water level and speed
Do not exceed the maximum water level
and maximum speed; otherwise, the vehicle's
engine, the electrical systems and the trans‐
mission may be damaged.◀
Drive though calm water only and only if it is
not deeper than 9.8 inches/25 cm and at this
height, no faster than walking speed, up to
3 mph/5 km/h.
Braking safely
Your vehicle is equipped with ABS as a stand‐
ard feature.
Applying the brakes fully is the most effective
way of braking in situations needed.
Steering is still responsive. You can still avoid
any obstacles with a minimum of steering ef‐
fort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
In certain braking situations, the perforated
brake discs can cause functional problems.
However, this has no effect on the perform‐
ance and operational reliability of the brake.
Objects within the range of movement
of the pedals
No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the pedal area; otherwise, the
function of the pedals could be impeded while
driving and create the risk of an accident.
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 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 or with the engine
stopped, as doing so disables engine braking.
In addition, steering and brake assist are un‐
available 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.
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.

7.With the ignition turned on or the engine
running, reel on the compressor.
Switch off the compressor after 10 mi‐
nutes
Do not allow the compressor to run longer than
10 minutes; otherwise, the device will overheat
and may be damaged.◀
Let the compressor run for approx. 3 to 8 mi‐
nutes to fill the tire with sealant and achieve a
tire inflation pressure of approx. 2.5 bar.
While the tire is being filled with sealant, the
tire inflation pressure may sporadically reach
approx. 5 bar. Do not reel off the compressor at
this point.
If a tire inflation pressure of 2 bar is not
reached:
1.Switch off the compressor.2.Unscrew the filling hose from the wheel.3.Drive 33 ft/10 m forward and back to dis‐
tribute the sealant in the tire.4.Inflate the tire again using the compressor.
If a tire inflation pressure of 2 bar cannot be
reached, contact your service center.
Stowing the Mobility System
1.Remove the connection hose of the seal‐
ant container from the wheel.2.Remove the connection hose from the
sealant container.3.Wrap the empty sealant container and con‐
nection hose in suitable material to avoid
dirtying the cargo area.4.Stow the Mobility System back in the vehi‐
cle.
Distributing the sealant
Immediately drive approx. 5 miles/10 km to en‐
sure that the sealant is evenly distributed in the
tire.
Do not exceed a speed of 50 mph/80 km/h.
If possible, do not drive at speeds less than
12 mph/20 km/h.
To correct the tire inflation pressure
1.Stop at a suitable location.2.Screw the connection hose onto the tire
valve stem.3.Attach the connection hose directly to the
compressor.Seite 201Wheels and tiresMobility201
