Driving comfortVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series. Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
When using the features and systems descri‐
bed here, adhere to local regulations.
Cruise control The concept
Cruise control is available for use at speeds of
approx. 20 mph/30 km/h and higher. The car
then stores and maintains the speed that you
specify using the lever on the steering column.
In order to maintain the specified speed, the
system brakes the vehicle when the engine
braking effect is insufficient on downhill gradi‐
ents.
Do not use cruise control
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, for instance:▷On curvy roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
Otherwise, you could lose control of the vehi‐
cle and cause an accident.◀
Manual transmission
You can shift gears while cruise control is acti‐
vated. An indicator lamp notifies you that you
should shift gears when you drive for an ex‐
tended period at very high or very low engine
speeds, or the system is deactivated.

Maintaining current speed
Push the lever, arrow 1, or pull it briefly, ar‐
row 2.
The car's current speed is stored and main‐
tained. It is displayed on the speedometer and briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking ef‐
fect is insufficient on downhill slopes, the sys‐
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow 1, until the desired
speed is reached.
▷Each time the lever is pressed to the point
of resistance, the desired speed increases
by approx. 1 mph/1 km/h.Seite 105Driving comfortControls105

To give the automatic climate control enough
time to achieve the set temperature, do not
switch between different temperature settings
in quick succession.
Maximum heating power can be obtained with
the highest setting, regardless of the external
temperature.
The lowest setting effects continuous cooling.
Switching the cooling function on and
off
The cooling function cools and
dehumidifies the incoming air be‐
fore reheating it as required, ac‐ cording to the temperature set‐
ting. This function is only available
while the engine is running.
The cooling function helps to prevent conden‐
sation on the windows or to remove it quickly.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is switched on automati‐
cally with the AUTO program.
Maximum cooling The air is cooled as quickly as
possible with the engine running.
The automatic climate control goes into recir‐
culated air mode at the lowest temperature. Air
flows at maximum rate from the vents for the
upper body area. You should therefore open
the vents for maximum cooling.
AUTO program
The AUTO program automatically adjusts the
air distribution to the windshield and side win‐
dows, toward the upper body area, and into the
footwell and knee area.
The air flow rate and air distribution, in addition
to your temperature specifications, will be
adapted to outside influences as a result ofseasonal changes, e.g., sunlight or window
condensation.
The cooling function is switched on automati‐
cally with the AUTO program.
Switching on/off Press the button.
Manual air distribution and air flow
rate are activated when the AUTO program is
deactivated.
AUTO program climate level
The climate levels can be used to vary the in‐
tensity when the AUTO program is switched
on. For example, air flow is adjusted automati‐
cally to optimize climate control.
When the AUTO program is
switched on, the climate level of
the AUTO program can be se‐
lected using the buttons for controlling the
manual air flow rate.
The selected climate level is displayed by an
LED.
Convertible program
When the hardtop is open, the convertible pro‐
gram is activated as well. In the convertible
program, the automatic climate control is opti‐
mized for driving with the hardtop open. In ad‐
dition, the air flow rate is increased as vehicle
speed increases.
The effectiveness of the convertible program
can be enhanced considerably by installing the
wind deflector.

▷Left LED on, automatic recirculated air
control: a sensor detects pollutants in the
outside air. If necessary, the system blocks
the supply of outside air and recirculates
the inside air. As soon as the concentration
of pollutants in the outside air has de‐
creased sufficiently, the system automati‐
cally switches back to outside air supply.▷Right LED on, recirculated air mode: the
supply of outside air into the vehicle is per‐
manently blocked. The system then recir‐
culates the air currently within the vehicle.
Adjusting air flow rate manually
Press the left side of the button to
reduce air flow. Press the right
side of the button to increase it.
The air volume may be reduced automatically
to save battery power. The display remains the
same.
Air distribution, manual
Depending on the selected setting, the air is
directed to the windshield, to the upper body
area, to the knee area and into the footwell.
Adjusting air distribution manually Press the button repeatedly until
the air distribution is set as re‐
quired. The corresponding LED lights up.
The manual air distribution is also switched on
when the AUTO program is deactivated.
Residual heat
The heat stored in the engine is used to heat
the interior.
This function can be switched on
using the right-hand button under
the following conditions:
▷Up to 15 minutes after switching off the
engine.▷When the engine is warm.▷With sufficient battery voltage.▷At an external temperature under
77 ℉/25 ℃.
The middle LED is lit when the function is on.
Defrosting and defogging windows Quickly removes ice and conden‐
sation from the windshield and
front side windows.
For this purpose, also switch on the cooling
function.
Rear window defroster The defroster switches off auto‐
matically after a certain time or
when the hardtop is opened.
Microfilter/activated-charcoal filter
The microfilter traps dust and pollen in the in‐
coming air. The activated-charcoal filter pro‐
vides additional protection by filtering gaseous
pollutants from the outside air. Your service
center replaces this combined filter during rou‐
tine maintenance.

Danger of burns
Only hold the hot lighter by its head; oth‐
erwise, there is the danger of getting burned.
Switch off the ignition and take the remote
control with you when leaving the vehicle so
that children cannot use the lighter and burn
themselves.◀
Replace the cover after use
Replace the lighter or socket cover after
use; otherwise, objects that fall into the lighter
socket or power socket could cause a short
circuit.◀

devices
Note Do not connect the charger to the socket
Do not connect the battery charger to
the socket installed in the vehicle at the factory
as this could damage the vehicle.◀
Sockets
In your BMW, when the engine is running or
the ignition is switched on, you can use electri‐
cal devices such as a hand lamp, car vacuum
cleaner, etc., as long as one of the following
sockets is available. The total load of all sock‐
ets must not exceed 140 watts at 12 V. Avoid
damaging the sockets by attempting to insert
plugs of unsuitable shape or size.

Objects in the area around the pedalsNo 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 fas‐
tened again when they are returned after being
removed, such as for cleaning.◀
Driving in wet conditionsWhen roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles.
Ensure that this action does not endanger
other road users.
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
Drive long or steep downhill gradients in the
gear in which the least braking is required.
Otherwise, the brake system may overheat, re‐
sulting in a reduction in the brake system effi‐
ciency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if necessary.
Downshifting in manual mode of the 8-gear
Sport automatic transmission, refer to
page 67.
Downshifting in manual mode of the 7-gear
Sport automatic transmission with dual clutch,
refer to page 70.Avoid load on the brakes
Avoid placing excessive load on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brake wear
and possibly even brake failure.◀
Do not drive in neutral
Never drive with the transmission in neu‐
tral, with the engine switched off or with the
clutch depressed; otherwise, you will have nei‐
ther the braking action of the engine or nor its
power assistance when braking or steering.◀
Brake disc corrosion Corrosion on the brake discs and contamina‐
tion on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops that exits under‐
neath the vehicle.
Therefore, traces of condensed water under
the vehicle are normal.
Loading Overloading the vehicle
To avoid exceeding the approved carry‐
ing capacity of the tires, never overload the ve‐
hicle. Overloading can lead to overheating and
increases the rate at which damage develops

Remove attached parts following use
Remove auxiliary mirrors or rear-mounted lug‐
gage racks after use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.
Close both windows
An open window causes higher air resistance
and thus increases fuel consumption.
Tires
General information
Tires can have varying effects on fuel con‐
sumption; for example, fuel consumption can
be influenced by the tire size.
Check the tire inflation pressure
regularly
Check and, if necessary, correct the tire infla‐
tion pressure, refer to page 228, at least twice
a month and before starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away without delay Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate engine speeds.
This is the fastest way for the cold engine to
reach its operating temperature.
Look well ahead when driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐ cle driving ahead of you.
Driving smoothly and looking ahead reduces
fuel consumption.
Avoid high engine speeds Use 1st gear to get the vehicle in motion. Be‐
ginning with 2nd gear, accelerate rapidly.When accelerating, shift up before reaching high engine speeds.
When you reach the desired speed, shift into
the highest applicable gear and drive with the
engine speed as low as possible and at a con‐
stant speed.
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Use coasting conditions When approaching a red light, take your foot
off the accelerator and coast to a halt in the
highest applicable gear.
On a downhill slope, take your foot off the ac‐
celerator and coast in a suitable gear.
The flow of fuel is interrupted while coasting.
Switch off the engine during longer
stops
Switch off the engine during longer stops, e.g.,
at traffic lights, railroad crossings or in traffic
congestion.
Automatic Engine Start/Stop Function The Automatic Engine Start/Stop Function au‐
tomatically switches the engine off during a
stop.
If the engine is stopped and then started again,
fuel consumption and emissions drop com‐
pared to an engine that runs permanently.
Stopping the engine even for just a few sec‐
onds can result in savings.
Use of this system can cause premature wear
on certain vehicle components.
In addition, fuel consumption depends on
other factors as well, such as driving style, road
conditions, maintenance, and environmental
factors.
Additional information on the Automatic En‐
gine Start/Stop Function, refer to page 59.Seite 135Things to remember when drivingDriving tips135
