2012 BMW 128I engine

Driving
64 The engaged gear, e.g. M1 is displayed in the
instrument cluster.
In the following situations, the 7-gear Sport
automatic transmission with double clutch
does the thinking for you:
>Upshifts and downshifts are executed only
when they will result in a plausible combina-
tion of engine and vehicle speed; thus, for
example, a downshift that could cause the
engine to overrev will not be executed by
the system.
>At a stop, the transmission is automatically
shifted down to the first gear.
>Shortly before the speed falls below a gear-
dependent minimum speed, the transmis-
sion automatically downshifts without your
intervention.
Quick downshifting: even in sequential mode,
you can skip over several gears in order to
achieve an optimum acceleration. To do so,
depress the accelerator past the resistance
point.
To return to automatic mode, push the selector
lever to the right.
Gear shifting
Upshift or downshift using the selector lever or
the shift paddles. You do not need to lift your
foot off the accelerator when doing so.
Using the selector lever
>To upshift, pull the selector lever toward the
rear.
>To downshift, push it toward the front.
Using the shift paddles on the steering
wheel
You can also shift manually using two shift pad-
dles on the steering wheel. The shift paddles
allow you to shift gears quickly since both
hands can remain on the steering wheel.
>When you use the shift paddles on the
steering wheel to shift gears in automatic
mode, the transmission switches to manual
mode.>If you do not accelerate or shift gears using
the shift paddles for a certain amount of
time, the transmission switches back to
automatic mode if the selector lever is in
position D.
>To upshift, briefly pull the right shift
paddle +.
>To downshift, briefly pull the left shift pad-
dle –.
Driving dynamics control
The driving dynamics control permits you, at
the push of a button, to have your BMW react in
an even more sporty fashion when driving:
>Optimal use is made of the engine's speed
range.
>Gear changes occur more quickly.
>The engine reacts more spontaneously to
accelerator pedal movements.
Activating the system
Press the SPORT button.
The LED in the button lights up.
Deactivating the system
>Press the SPORT button again
>Switch off the engine

Launch Control
Launch Control enables an optimum accelera-
tion when starting off on a road surface with
good traction.
Do not use Launch Control too often; oth-
erwise, the powerful stresses on the vehi-
cle will lead to premature component wear.<
Launch Control is ready for use when the
engine is at operating temperature, i.e. after
uninterrupted travel of at least 6.2 miles/10 km.
1.With the engine running, step on the brake
with your left foot.
2.Activate Dynamic Traction Control (DTC),
refer to page84.
3.Activate Driving dynamics control, refer to
page64.
4.With the vehicle stationary, activate the
manual mode and select 1
stgear.
5.With your right foot, push the accelerator
pedal past the resistance point. The engine
speed for pulling away is adjusted. A flag
symbol appears in the instrument cluster.
6.When you release the brake pedal, the vehi-
cle accelerates. Keep the accelerator pedal
floored.
7.The upshifting occurs automatically as long
as you keep the accelerator pedal pressed
past the resistance point.
Launch Control will be ready for use again after
you drive a certain distance.
Launch Control is not available for use during
the break-in phase, refer to page116.
To maintain driving stability, keep DSC
activated whenever possible.<

Using turn signals
Press the lever beyond the resistance point.
To turn off manually, press the lever to the
resistance point.
Unusually rapid flashing of the indicator

one of the turn signal bulbs has failed.<
Signaling a turn briefly
Press the lever as far as the resistance point for
as long as you wish to signal a turn.
Triple turn signal activation
Press the lever as far as the resistance point.
The turn signals flash three times.

Windshield washer nozzles
The windshield washer nozzles are heated
automatically
* while the engine is running or
the ignition is switched on.
Washer fluid
Washer fluid is flammable. Therefore,
keep it away from ignition sources and
only store it in the closed original container that
is kept out of reach of children; otherwise, there
is a risk of personal injury. Comply with the
instructions on the container.<
Washer fluid filler neck
Only refill washer fluid when the engine is
cool to avoid contact with hot engine
parts. Otherwise, fluid spills constitute a fire
hazard and a risk to personal safety.<
All washer nozzles are supplied with washer
fluid by the same reservoir.
Fill with water and, if required, with a washer
antifreeze, according to manufacturer's recom-
mendations.
Mix the water and antifreeze before filling
the washer fluid reservoir to make sure
the correct concentration is maintained.<
Capacity
Approx. 6.3 US quarts/6 liters.
Cruise control*
The concept
You can use the cruise control feature begin-
ning at approx. 20 mph/30 km/h. The car then
stores and maintains the speed that you specify
using the lever on the steering column.
Do not use cruise control when driving at
constant speed is prevented by adverse
conditions, e.g. winding roads, dense traffic or
poor road conditions due to, e.g. snow, rain, ice
or loose surfaces. Otherwise, you could lose
control of the vehicle and cause an accident as a
result.<

4Resuming a previously stored speed
Maintaining current speed
Briefly press the lever, arrow 1, or pull it briefly,
arrow 2.
The car's current speed is stored and main-
tained. It is briefly displayed in the instrument
cluster.
If the engine braking power is insufficient on a
downhill slope, the set speed may be exceeded.
On uphill grades vehicle speed may drop if the
engine output is insufficient.

Outside temperature warning
When the displayed temperature falls to approx.
+377/+36, a signal sounds and a warning
lamp lights up. There is an increased risk of
black ice.Black ice can also form at temperatures
above +377/+36. You should there-
fore drive carefully on bridges and shaded
roads, for example; otherwise, there is an
increased risk of an accident.<

Engine oil temperature*
When the engine is at normal operating temper-
ature, the engine oil temperature is between
approx. 2107/1006 and approx. 3007/
1506.
If the engine oil temperature is too high, a mes-
sage appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 14 US gal/53 liters.
You can find information on refueling on
page206.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Fuel display 135i: in speedometer.
Reserve
Once the fuel level has fallen to the reserve
zone, a message briefly appears on the Control
Display and the remaining cruising range is dis-
played on the computer. Under a cruising range
of approx. 30 miles/50 km, the message
appears continuously in the Control Display.With a dynamic driving style, e.g. rapid corner-
ing, engine functions are not always assured.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km; otherwise, engine functions are not
ensured and damage can occur.<

Cruising range
Displays the estimated cruising range available
with the remaining fuel. The range is calculated
on the basis of the way the car has been driven
over the last 18 miles/30 km and the amount of
fuel currently in the tank.
It is important that you refuel as soon as
possible once your cruising range falls
below 30 miles/50 km; otherwise, engine func-
tions are not ensured and damage can occur.<
Average speed
Periods with the vehicle parked and the engine
switched off are not included in the calculations
of average speed.
With the trip computer, refer to page73, you
can have the average speed for another trip dis-
played.
To reset average speed: press the button in the
turn signal/high beam lever for approx.
2seconds.
Average fuel consumption
The average fuel consumption is calculated for
the time during which the engine is running.
With the trip computer, refer to page73, you
can have the average consumption for another
trip displayed.
To reset average fuel consumption: press the
button in the turn signal/high beam lever for
approx. 2 seconds.
Current fuel consumption
Displays the current fuel consumption. This
allows you to see whether your current driving
style is conducive to fuel economy with mini-
mum exhaust emissions.
