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.

ating3Deactivating cruise control4Resuming a speed stored beforehand
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

Switching on automaticallyEngage reverse gear with the engine running
or the ignition switched on.
Switching off automatically when
driving forward
The system switches off when a certain dis‐
tance or speed is exceeded.
Switch on the system again if necessary.
Signal tones When approaching an object, an intermittent
tone is sounded that indicates the position of
the object. For example, if an object is de‐
tected to the left rear of the vehicle, a signal
tone sounds from the left rear speaker.
The shorter the distance to the object be‐
comes, the shorter the intervals.
If the distance to a detected object is less than
approx. 10 in/25 cm, a continuous tone is
sounded.
If objects are located both in front of and be‐
hind the vehicle, an alternating continuous sig‐
nal is sounded.
The intermittent tone is interrupted after ap‐
prox. 3 seconds:▷If the vehicle stops in front of an object that
is detected by only one of the corner sen‐
sors.▷If moving parallel to a wall.
The signal tone is switched off:
▷When the vehicle moves away from an ob‐
ject by more than approx. 4 in/10 cm.▷When transmission position P is engaged.
Volume
You can set the volume of the PDC signal, refer
to page 163.
The setting is stored for the remote control
currently in use.
Visual warning
The approach of the vehicle to an object is
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis‐
play before a signal sounds. The display ap‐
pears as soon as PDC is switched on.
Malfunction The indicator lamp in the instrument
cluster comes on. PDC has failed.
A message appears on the Control Display.
Have the system checked.
To ensure full operability:▷Keep the sensors clean and free of ice.▷When using high-pressure washers, do not
spray the sensors for long periods and
maintain a distance of at least 12 in/30 cm.Seite 108ControlsDriving comfort108

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.

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.

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 limits.
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road
speeds:▷4,500 rpm and 100 mph/160 km/h.
Do not drive with full-throttle operation, and do
not use the transmission's kickdown mode or
Launch Control.
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
traction potential until after an initial breaking-
in period.
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 cautiously during this break-in
period.
Clutch
The clutch requires an initial break-in period of
approx. 300 miles/500 km to function at an op‐
timal level.
During this break-in period, engage the clutch
gently.
Following part replacement
The same breaking in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
General driving notes
Ground clearance Limited ground clearance
Note that the Z4 sDrive35 has limited
ground clearance, for instance when driving
into underground parking garages or over ob‐
stacles. Otherwise, the vehicle may be dam‐
aged.◀Seite 130Driving tipsThings to remember when driving130
