7-gear Sport automatic
transmission with dual clutch
The concept This transmission is an automated manual
transmission with two clutches and two gear‐
box components in which the gears are
changed without loss of torque.
The transmission is operated using the selec‐
tor lever and two shift paddles on the steering
wheel.
Functions:▷Choice of manual or automatic operation:
manual mode or Drive mode.▷Automatic downshifting and protection
against selecting the wrong gear, even in
manual mode.▷Acceleration assistant, Launch Control, re‐
fer to page 71.▷Automatic throttle blip.
System limits
This transmission is equipped with an over‐
heating protection system that protects the
clutches against extremely high loads.
The indicator lamp lights up yellow if
the transmission becomes too warm.
Avoid high engine loads and driving
off frequently.
If the transmission overheats, the indicator
lamp lights up red and power flow to the en‐
gine is interrupted. You can only continue driv‐
ing after the transmission has cooled down.
Avoid driving off frequently with high accelera‐
tion and do not hold the vehicle on inclines by
depressing the accelerator lightly; otherwise,
the transmission may overheat.

when they will result in a feasible combina‐
tion of engine and vehicle speed; thus, for
example, a downshift that would cause the
engine to overrev will not be executed by
the system.▷When the vehicle stops, the transmission
automatically shifts down to first gear.▷Shortly before the vehicle slows down to
below the minimum speed of the gear cur‐
rently engaged, the transmission automati‐
cally shifts down without requiring your in‐
tervention.

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
Online Edition for Part no. 01 40 2 954 104 - II/15

▷Each time the lever is pressed beyond the
resistance point, the desired speed is in‐
creased by up to 5 mph/10 km/h.
The system stores and maintains the speed.
Accelerating using the lever
Accelerating slightly:
Press the lever to the resistance point, arrow 1,
and hold until the desired speed is reached.
Accelerating significantly:
Press the lever beyond the resistance point,
arrow 1, and hold until the desired speed is
reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores and
maintains the speed.
Decreasing speed Repeatedly pull the lever to the resistance
point or beyond, arrow 2, until the desired
speed is displayed.
▷Each time the lever is pulled to the resist‐
ance point, the desired speed is decreased
by approx. 1 mph/1 km/h.▷Each time the lever is pulled beyond the
resistance point, the desired speed is re‐
duced by up to 5 mph or 10 km/h until the
minimum speed of 20 mph/30 km/h is ach‐
ieved.
The system stores and maintains the speed.
Interrupting the system
Push the lever upwards or downwards, ar‐
row 3.
The displays in the speedometer change color.
In addition, the system is automatically inter‐
rupted in the following situations:
▷When the brakes are applied.▷In cars with manual transmission, when
gears are shifted very slowly or if neutral is
engaged.▷In cars with Sport automatic transmission,
when transmission position N is engaged.▷When DTC is activated or DSC is deacti‐
vated.▷When DSC or ABS is intervening.
Cruise control is not deactivated by depressing
the accelerator pedal. Once the accelerator
pedal is released, the stored speed is achieved
again and maintained.
Warning light A message appears on the Control
Display.
The warning light comes on, for ex‐
ample, when cruise control has been deacti‐
vated as a result of DSC intervention.
Deactivating the system
▷Press the lever upward or downward twice,

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

Things to remember when drivingVehicle 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.
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

Closing the trunk lidDrive with the trunk lid closed
Only operate the vehicle with the trunk
lid closed; otherwise, exhaust fumes could en‐
ter the passenger compartment.◀
If the vehicle must be driven with the trunk lid
open:1.Close all windows.2.Greatly increase the air flow rate of the air
conditioner or automatic climate control.
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. Make sure
that flammable materials, e. g. hay, leaves,
grass, etc. do not come in contact with the hot
exhaust system during driving, while in idle po‐
sition mode, or when parked. Such contact
could lead to a fire, and with it the risk of seri‐
ous personal injury as well as property dam‐
age.
Do not touch hot exhaust pipes; otherwise,
there is the danger of getting burned.◀
Mobile communication devices in the
vehicle
Mobile communication devices in the ve‐
hicle
It is not recommended to use mobile phones,
such as mobile phones without a direct con‐
nection to an external aerial in the vehicle's
passenger compartment. Otherwise, the vehi‐
cle electronics and mobile communication de‐
vices can interfere with each other. In addition,
there is no assurance that the radiation gener‐
ated 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
electrical systems and the transmission may
be damaged.◀
Braking safely
Your vehicle is equipped with ABS as a stand‐
ard feature.
Applying the brakes fully is the most effective
way of braking in situations when this is neces‐
sary.
The vehicle maintains steering responsive‐
ness. 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.Seite 131Things to remember when drivingDriving tips131
