BMW 3 SERIES GRAN TURISMO 2018 Owners Manual

High-beam
AssistantConcept
The high-beam Assistant detects other traffic
participants early on and automatically
switches the high beams on or off depending
on the traffic situation.
General
information
The high-beam Assistant ensures that the high beams are switched on, whenever the traffic
situation allows. In the low speed range, the high beams are not switched on by the system.
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to
adequate illumination, for instance in towns
and cities.
The high beams can be switched on and off at
any time as usual.
Activating/deactivating
Position of switch, depending on the vehicle
equipment:
,
Press and hold button on signal lever.
The indicator light in the instrument
cluster is illuminated when the low
beams are switched on.
The headlights are automatically switched bej tween low beams and high beams.
The blue indicator light in the instruj
ment cluster lights up when the system
switches on the high beams.
The high-beam Assistant is deactivated when manually switching the high beams on and off,
refer to page 90.
To reactivate the high-beam Assistant, press the button on the turn signal lever.
System
limits
The high-beam Assistant cannot serve as a substitute for the driver's personal judgment of
when to use the high beams. In situation that require this, therefore switch off manually.
The system is not fully functional in the followj ing situations, and driver intervention may be
necessary:'yIn very unfavorable weather conditions,
such as fog or heavy precipitation.'yWhen detecting poorly-lit road users such
as pedestrians, cyclists, horseback riders
and wagons; when driving close to train or ship traffic; and at animal crossings.'yIn tight curves, on hilltops or in depresj
sions, in cross traffic or half-obscured onj coming traffic on highways.'yIn poorly-lit towns and cities and in thepresence of highly reflective signs.'yWhen the windshield in front of the interior
mirror is fogged over, dirty or covered with stickers, etc.

SafetyVehicle
features
and
options
This chapter describes all standard, country- specific and optional features offered with theseries. It also describes features that are notnecessarily available in your vehicle, e. g., dueto the selected options or country versions.
This also applies to safety-related functions
and systems. When using these functions and systems, the applicable laws and regulations
must be observed.
Airbags

airbags
Front airbags help protect the driver and the front passenger by responding to frontal imj
pacts in which safety belts alone would not
provide adequate protection.Side

In a lateral impact, the side airbag supports the
side of the body in the chest and lap area.

Ejection
MitigationThe head airbag system is designed as anejection mitigation countermeasure to reducethe likelihood of ejections of vehicle occupantsthrough side windows during rollovers or sideimpact events.
Knee
airbag The knee airbag supports the legs in a frontal
impact.
Protective
action
Airbags are not triggered in every impact situaj
tion, e.g., in less severe accidents or rear-end collisions.
Information
on
optimum
effect
of
theairbags
WARNING
If the seat position is incorrect or the dej
ployment area of the airbags is impaired, the airbag system cannot provide protection as injtended and may cause additional injuries dueto triggering. There is a risk of injuries or danjger to life. Follow the information on achieving
the optimum protective effect of the airbag system.'

WARNING
Improperly executed work can lead to
failure, malfunction or unintentional triggering of the airbag system. In the case of a malfuncj
tion, the airbag system might not trigger as inj
tended despite the accident severity. There is
a risk of injuries or danger to life. Have the airj bag system checked, repaired, dismantled andscrapped by a dealerss service center or anjother qualified service center or repair shop.'

Indicator
lamp
for
the
front-seat
passenger
airbags
The indicator lamp for the front-seat passenj ger airbags indicates the operating state of thefront-seat passenger airbags.
The lamp indicates whether the airbags are eij
ther activated or deactivated.
'yThe indicator lamp lights up
when a child is properly
seated in a child restraint fixj
ing system or when the seat
is empty. The airbags on the
front passenger side are not
activated.'yThe indicator lamp does not light up when, e.g., a correctly seated person of sufficient
size is detected on the seat. The airbags
on the front passenger side are activated.
Detected
child
restraint
systems
The system generally detects children seated in a child restraint system, particularly in child
restraint systems required by NHTSA at the
point in time when the vehicle was manufacj
tured. After installing a child restraint system,
make sure that the indicator light for the front-
seat passenger airbags lights up. This indij
cates that the child restraint system has been detected and the front-seat passenger airbags
are not activated.
Strength
of
the
driver's
and
front-seat
passenger
airbag
The explosive power that activates driver's/
front-seat passenger airbags very much dej
pends on the positions of the driver's/front
passenger seat.
To maintain the accuracy of this function over the long term, calibrate the front seats as soon
as a respective message appears on the Conj
trol Display.
Calibrating
the
front
seats WARNING
There is a risk of jamming when moving
the seats. There is a risk of injury or risk of property damage. Make sure that the area ofmovement of the seat is clear prior to any adjjustment.'

General
information
Sensors in the tire valves measure the tire inj
flation pressure and, depending on the model,
the tire temperature.
With use of the system follow further informaj
tion found under Tire inflation pressure, refer
to page 226.
Functional
requirements The following conditions must be met for the
system; otherwise, reliable flagging of a loss of
tire inflation pressure is not assured:'yAfter a tire or wheel replacement, a reset
was performed with the correct tire inflaj
tion pressure.'yAfter the tire inflation pressure was adj
justed to a new value, a reset was perj
formed.'yWheels with TPM wheel electronics.

tions.

After a successfully completed reset, the
wheels on the Control Display are shown in green and "Tire Pressure Monitor active. Seelabel for recommended pressures." is disj
played.
You may interrupt this trip at any time. When you continue the reset resumes automatically.
Messages
General
information
A low tire inflation pressure may cause the
DSC Dynamic Stability Control to be switched
on.
Safety
information WARNING
A damaged regular tire with low or missj
ing tire inflation pressure impacts handling, such as steering and braking response. Run-flat tires can maintain limited stability. There is
a risk of an accident. Do not continue driving if the vehicle is equipped with normal tires. Foljlow the information on run-flat tires and continj
ued driving with these tires.'

3.Reset the system.
If

Message A yellow warning light is illuminated inthe instrument cluster.
In addition, a symbol with the affected tire apj
pears in a Check Control message on the Conj
trol Display.
SymbolPossible causeThere is a flat tire or a major loss in
tire inflation pressure.
No reset was performed for the sysj tem. The system issues a warning
based on the tire inflation pressures
stored during the last reset.
Measure
1.Reduce your speed and stop cautiously. Avoid sudden braking and steering maneujvers.2.Check whether the vehicle is fitted with
normal tires or run-flat tires.
Run-flat tires, refer to page 234, are laj
beled with a circular symbol containing the letters RSC marked on the tire's sidewall.
Actions
in
the
event
of
a
flat
tire
Normal
tires
1.Identify the damaged tire.
To do this, check the air pressure in all four
tires, for instance using the tire pressure gage of a flat tire kit.
If the tire inflation pressure in all four tires
is correct, the Tire Pressure Monitor may
not have been reset. In this case, perform the reset.If identification of flat tire damage is notpossible, please contact a dealerss servicecenter or another qualified service center
or repair shop.2.Repair the flat tire, e.g., with a flat tire kit or
by changing the wheel.
Use of sealant, for instance from the flat tire kit, may damage the TPM wheel electronics. In
this case, have the electronics checked and rej
placed at the next opportunity.
Run-flat
tires
Safety
information WARNING
Your vehicle handles differently with a
run-flat with no or low inflation pressure; for inj stance, your lane stability when braking is rejduced, braking distances are longer and theself-steering properties will change. There is a
risk of an accident.
Drive moderately and do not exceed a speed of 50 mph/80 km/h.'
