Drive-off assistant
This system supports driving away on gradients.
The parking brake is not required.
1.Hold the vehicle in place with the foot brake.2.Release the foot brake and drive away with‐
out delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driving
without delay, since the drive-off assistant will
not hold the vehicle in place for more than ap‐
prox. 2 seconds and the vehicle will begin rolling
back.◀
Servotronic
The concept
The Servotronic varies the steering force re‐
quired to turn the wheels depending on the
speed at which you are driving. Power steering
provides strong support at low speeds, which
means that little effort is needed to turn the
wheels. Power steering support lessens as your
speed increases.
The system works automatically.

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 sys‐
tems.
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 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.
Otherwise, you could lose control of the vehicle
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, arrow 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 effect
is insufficient on downhill slopes, the system 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.▷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, ar‐
row 1, and hold until the desired speed is
reached.
The vehicle accelerates without pressure on the
accelerator pedal. The system stores and main‐
tains 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 re‐
sistance point, the desired speed is reduced
by up to 5 mph or 10 km/h until the minimum
speed of 20 mph/30 km/h is achieved.
The system stores and maintains the speed.
Interrupting the system
Push the lever upwards or downwards, arrow 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 lamp The warning lamp comes on, for ex‐
ample, when cruise control has been
deactivated as a result of DSC inter‐
vention.
Deactivating the system▷Press the lever upward or downward twice,
arrow 3.▷Switch off the ignition.
The stored speed is cleared.
Resuming a speed stored beforehand
Press the button, arrow 4. The last stored speed
is resumed and maintained.

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 sys‐
tems.
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 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 rotors. 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 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
Ground clearance Limited ground clearance
Note that the Z4 sDrive35 has limited
ground clearance, for instance when driving into
underground parking garages or over obstacles.
Otherwise, the vehicle may be damaged.◀
Closing the trunk lid Drive with the trunk lid closed
Only operate the vehicle with the trunk lid
closed; otherwise, exhaust fumes could enter
the passenger compartment.◀Seite 108Driving tipsThings to remember when driving108
Online Edition for Part no. 01 40 2 609 184 - 09 11 500

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 position
mode, or when parked. 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.◀
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 connec‐
tion to an external aerial in the vehicle's passen‐
ger compartment. 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.Seite 109Things to remember when drivingDriving tips109
Online Edition for Part no. 01 40 2 609 184 - 09 11 500

Ensure that the floor mats are securely fastened
again when they are returned after being re‐
moved, such as for cleaning.◀
Driving in wet conditions
When 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, resulting in a
reduction in the brake system efficiency.
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 54.
Downshifting in manual mode of the 7-gear
Sport automatic transmission with dual clutch,
refer to page 57.
Avoid load on the brakes
Avoid placing excessive load on the brake
system. Light but consistent brake pressure can
lead to high temperatures, brake wear and pos‐
sibly 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 contamination
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, con‐
densation water develops that exits underneath
the vehicle.
Therefore, traces of condensed water under the
vehicle are normal.
Loading Overloading the vehicle
To avoid exceeding the approved carrying
capacity of the tires, never overload the vehicle.
Overloading can lead to overheating and in‐
creases the rate at which damage develops in‐
side the tires. This could result in a sudden loss
of tire inflation pressure.◀
Secure heavy objects
Never transport unsecured heavy or hard
objects in the passenger compartment, as they
could be thrown around and pose a safety haz‐
ard to the vehicle's occupants during abrupt
braking or evasive maneuvers.◀
No fluids in the cargo area
Make sure that fluids do not leak into the
cargo area; otherwise, the vehicle may be dam‐
aged.◀

amount of maintenance you need to your user
profile.
Details on the service requirements, refer to
page 65, can be displayed on the instrument
cluster.
Service data in the remote control
Information on the required maintenance is con‐
tinuously stored in the remote control. Your
service center will read out this data and suggest
the right array of service procedures for your ve‐
hicle.
Therefore, hand your service specialist the re‐
mote control that you used most recently.Storage periods
Storage periods during which the vehicle bat‐
tery was disconnected are not taken into ac‐
