2011 BMW 7 SERIES brake

Driving comfort
Active Cruise Control with
Stop & Go function, ACC*
The concept
This system can be used to select a desired
speed that the vehicle will maintain automati‐
cally on clear roads.
To
the extent possible, the system automatically
adjusts the speed to a slower vehicle ahead of
you.
The distance that the vehicle maintains to the
vehicle ahead of you can be varied.
For safety reasons, it depends on the speed.
To maintain a certain distance, the system au‐
tomatically decelerates, applies the brakes
lightly, or accelerates again if the vehicle ahead
begins moving faster.
If the vehicle ahead of you brakes to a halt, the
system is able to detect this within the given
system limits. If the vehicle ahead of your drives
away again from a halt, your vehicle is able to
accelerate if operated accordingly.
Even if some time passes before the vehicle
drives away again, the BMW can still be accel‐
erated automatically and simply.
As soon as the road is clear, it accelerates to the
desired speed.
The speed is also maintained on downhill gra‐
dients, but may not be maintained on uphill
slopes if engine power is insufficient. Buttons at a glance 1

System limits
Be alert
Due to system limitations, warnings may
be not be issued at all, or may be issued late or
improperly. Therefore, always be alert and ready
to intervene; otherwise, there is the danger of an
accident occurring.◀ Detection range
The detection capacity of the radar sensor and
the collision warning has limitations.
This may result in the warning not being issued
or being issued late.
For

example, the following situations may not be
detected:
▷ Slow moving objects when you approach
them at high speed.
▷ Vehicles that suddenly swerve in front of
your vehicle.
▷ Two-wheeled vehicles ahead of you.
▷ Pedestrians.
Functional limitations
The system may not be fully functional in the
following situations:
▷ In heavy fog, rain or snowfall.
▷ In tight curves.
▷ If the radar sensor is dirty or covered.
Prewarning sensitivity
If the prewarning setting is too sensitive, there
may be an excess of false warnings.
Cruise control
The concept
The

system is functional at speeds beginning at
approx. 20 mph/30 km/h.
It maintains the speed that was set using the
control elements on the steering wheel.
The system brakes on downhill gradients if en‐
gine braking action is insufficient.
Unfavorable conditions
Do not use the system if unfavorable con‐
ditions make it impossible to drive at a constant
speed, for instance:
▷ On curvy roads.
▷ In heavy traffic.
▷ On slippery roads, in fog, snow or rain, or on
a loose road surface. Seite 111

Things to remember when driving
Breaking-in period
General information
Moving parts need to be broken in to adjust to
each other.
The following instructions will help achieve a
long vehicle life and good economy.
Engine and differential
Always obey the official speed limit.
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road
speed:
▷
For gasoline engine, 4500 rpm and
100 mph/160 km/h.
Avoid full-throttle operation and use of the
transmission's kickdown mode for the initial
miles.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
Tires
Due to technical factors associated with their
manufacture,
tires do not achieve their full trac‐
tion potential until after an initial breaking-in pe‐
riod.
Drive conservatively for the first 200 miles/
300 km.
Brake system
Brakes require an initial break-in period of ap‐
prox. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and discs. Drive moderately during this break-in
period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx. 300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The

same breaking in procedures should be ob‐
served if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
General driving notes
Closing the trunk lid
Drive with the trunk lid closed
Only drive with the tailgate closed; other‐
wise, in the event of an accident or braking or
evasive maneuvers, passengers or other road
users may be injured or the vehicle may be dam‐
aged. In addition, exhaust fumes may enter the
passenger compartment.◀
If driving with the tailgate open cannot be
avoided:
▷ Close all windows and the glass sunroof*.
▷ Greatly increase the blower speed.
▷ Drive moderately.
Hot exhaust system Hot exhaust system
High temperatures are generated in the
exhaust system.
Do not remove the heat shields installed and
never apply undercoating to them. When driv‐
ing,

standing at idle and while parking, take care
to avoid possible contact between the hot ex‐
haust system and any highly flammable materi‐
als such as hay, leaves, grass, etc. Such contact
could lead to a fire, and with it the risk of serious
personal injury as well as property damage.
Do not touch hot exhaust pipes; otherwise, there
is the danger of getting burned.◀ Seite 144

Things to remember when driving

Climate control windshield*
The marked area is not covered with heat re‐
flective coating.
Use this area for garage door openers, devices
for electronic toll collection, etc.
Climate
control laminated tinted safety
glass*
The vehicle glass provides full protection
against the harmful effects of UV radiation on the
skin.
Mobile communication devices in the
vehicle
Mobile communication devices in the ve‐
hicle
It is advised that you do not use mobile commu‐
nication devices, e.g., mobile phones, inside the
vehicle without connecting them directly to the
external antenna. Otherwise, the vehicle elec‐
tronics and mobile communication devices can
interfere with each other. In addition, there is no
assurance that the radiation generated during
transmission will be discharged from the vehicle
interior.◀
Hydroplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle. Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent hydroplaning.

◀
Driving through water
Drive though calm water only if it is not deeper
than 9.8 inches/25 cm and at this height, no
faster than walking speed, up to 6 mph/10 km/h. Adhere to water depth and speed limita‐
tions
Do not exceed this water depth and walking
speed; otherwise, the vehicle's engine, the elec‐
trical systems and the transmission may be
damaged.◀
Braking safely
Your vehicle is equipped with ABS as a standard
feature.
Applying the brakes fully is the most effective
way of braking in situations when this is neces‐
sary.
The vehicle maintains steering responsiveness.
You can still avoid any obstacles with a minimum
of steering effort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
Objects in the area around the pedals
No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving
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 fixed in place.
Ensure that the floor mats are securely fastened
again after they were removed for cleaning, for
example.◀ Seite 145
