instrument cluster BMW 128I CONVERTIBLE 2011 E88 Owner's Guide

Technology for driving comfort and safety
82 >When driving uphill on snow-covered roads,
in slush or on unplowed, snow-covered
roads
>When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
>When driving with snow chains
Activating DTC
Press the button; the indicator lamps for DTC in
the instrument cluster come on.
For better control
If the indicator lamp flashes:
DTC is regulating the drive and braking
forces.
If the indicator lamps are on:
DTC has been activated.
Deactivating DTC
Press the button again; the DTC indicator
lamps in the instrument cluster go out.
Drive-off assistant
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the parking brake for this.
1.Hold the car in place by depressing the
brake.
2.Release the brake and drive off without
delay.
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Drive off without delay after
releasing the brake. Otherwise, the drive-off assistant will no longer hold the car in place
after approx. 2 seconds and the car will start to
roll backwards.<
Flat Tire Monitor FTM*
The concept
The system does not measure the actual infla-
tion pressure in the tires.
The system detects a tire pressure loss due to
speed comparisons among the individual
wheels as you drive.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. The system detects this
and reports it as a flat tire.
Functional requirement
The system has to have been initialized at the
correct inflation pressure; otherwise, a reliable
reporting of a flat tire is not assured.
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reinitialize the system.
System limitations
It is impossible to provide advance warn-
ing of sudden, severe tire damage caused
by outside influences.<
The system will not detect a natural, uniform
pressure loss in all four tires. Therefore you
should check the inflation pressure regularly.
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration
>Driving with snow chains
*
Status display
The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.
whether or not the FTM is active.

Malfunction
The LED next to the symbol for automatic head-
lamp control flashes. Adaptive light control is
malfunctioning or has failed. Have the system
checked as soon as possible.
High beams/roadside parking
lamps*
1High beams
2Headlamp flasher
3Roadside parking lamps
*
Roadside parking lamps, left or right*
There is an additional option of switching on the
lamps on the side of the car facing the road
when parked.
Switching on
After parking the vehicle, press the lever up or
down beyond the pressure point for approx.
1 second, arrow 3.
The roadside parking lamps drain the bat-
tery. Therefore, do not leave them on for
unduly long periods of time; otherwise, the bat-
tery might not have enough power to start the
engine.<
Switching off
Press the lever in the opposite direction to the
pressure point, arrow 3.
High-beam assistant*
The concept
This system automatically switches the high
beams on and off. The procedure is controlled
by a sensor on the front of the interior rearview
mirror. The assistant ensures that the high
beams are switched on whenever the traffic sit-
uation allows. It handles this task for you and
gives you the benefit of the best possible view.
You can intervene at any time and switch the
high beams on and off as usual.
Activating the system
1.Turn the light switch to position3, refer to
page91.
2.With the low beams switched on, briefly
push the turn signal/high beam lever in the
direction of the high beam.
The indicator lamp in the instrument
cluster lights up when the high beams
are activated. The system automati-
cally switches from high beams to low beams
and vice versa in response to oncoming traffic,
traffic ahead of you, and adequate ambient
lighting, e.g. on city streets.
Switching the high beams on and off
manually
Whenever you wish, or when the situation
requires, you can intervene:
>If the high-beam assistant switches on the
high beams, but you would like to drive with
the low beams, simply switch off the high
beams using the turn signal/high beam
lever. This deactivates the high-beam
assistant.
To reactivate the system, briefly push the
turn signal/high beam lever toward the high
beams again.
>If the high-beam assistant switches on the
low beams, but you would like to drive with
the high beams, switch on the high beams
as usual. This deactivates the system and
the high beams need to be switched off
manually, if necessary.

Lamps
94 To reactivate the system, briefly push the
turn signal/high beam lever toward the high
beams again.
>Use the headlamp flasher as usual with the
low beams switched on.
System limitations
The high-beam assistant cannot serve as
a substitute for the driver's personal judg-
ment of when to use the high beams. Therefore,
manually switch off the high beams in situations
where this is required to avoid a safety risk.<
The system is not fully functional in situations
such as the following, and driver intervention
may be necessary:
>In very unfavorable weather conditions,
such as fog or heavy precipitation
>In 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
>In tight curves, on hilltops or in depressions,
in cross traffic or half-obscured oncoming
traffic on highways
>In poorly lit towns and cities and in the pres-
ence of highly reflective signs
>At low speeds
>When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov-
ered with stickers, etc.
>If the sensor is dirty. Clean the sensor on
the front of the interior rearview mirror using
a cloth moistened with a small amount of
glass cleaner.
Activating via iDrive
1."Settings"
2."Lighting"3."High beam assistant"
The high-beam assistant is activated and is
stored for the remote control currently in use.
Fog lamps*
To switch on/off, press the button.
The parking lamps or low beams must
be switched on for the fog lamps to
operate. The green indicator lamp in
the instrument cluster lights up whenever the
fog lamps are on.
The fog lamps are switched off while you acti-
vate the headlamp flasher or switch on the high
beams.
If the automatic headlamp control is acti-
vated, the low beams will come on auto-
matically when you switch on the fog lamps.<

Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking oil level
Your car is equipped with an electronic oil-level
monitor.
For precise measurement and display of the oil
level, the engine must be at operating tempera-
ture, i.e. following at least 6.2 miles/10 km of
uninterrupted driving. You can have the oil level
displayed while you are driving, or while the
vehicle is at a standstill on a level surface and
the engine is running.
Display in the instrument cluster
1.Push button1 in the turn indicator lever up
or down repeatedly until the appropriate
symbol is shown in the display, accompa-
nied by the word "OIL".
2.Press button2.
The oil level is checked and the reading dis-
played.

Care
212 Clean light-colored leather more frequently as
dust and dirt are more noticeable.
Treat the leather at least once every two
months using a leather lotion as dirt and grease
will gradually attack the leather's protective
layer.
Carpet/floor mats*
The floor mats can be removed for cleaning.
When heavily soiled, clean carpets with a
microfiber cloth and water or textile cleaner.
Rub back and forth in the direction of travel; oth-
erwise, the carpet may become matted.
Interior plastic parts
>Imitation leather surfaces
>Lamp glasses
>Display pane of instrument cluster
>Matte parts
Clean with water and solvent-free plastic
cleaner if necessary.
Fine wood parts
Clean fine wood trim and fine wood parts with a
damp cloth. Wipe dry with a soft cloth.
Safety belts
Dirty belt straps impede the reeling action and
thus have a negative impact on safety.
Do not clean chemically, as this may
destroy the webbing.<
Interior sensors/cameras
To clean interior sensors and cameras, e.g. of
the high-beam assistant, use a lint-free cloth
moistened with glass cleaner.
Displays
To clean displays, e.g. of the radio or instrument
cluster, use a cleaning cloth for displays or a
soft, non-abrasive, lint-free cloth.
Avoid applying excessive pressure when
cleaning the displays; otherwise, damage
may occur. hold cleaning agents. Keep all types of
fluid away from the device. Otherwise, surfaces
or electrical components may be corroded or
damaged.<
CD/DVD drives
Do not use a cleaning CD, as it may dam-
age parts of the drive.<
Vehicle storage
If your vehicle is to be decommissioned for
longer than three months, your BMW center or
a workshop that operates according to BMW
specifications will be glad to advise you.
