2015 BMW Z4 clutch

▷If the shift paddles are not used and the ve‐
hicle is not accelerated for a certain time,
the system switches back into automatic
mode if the selector lever is in transmission
position D.▷Shift up: pull right shift paddle.▷Shift down: pull left shift paddle.
The vehicle only shifts up or down at appropri‐
ate engine and road speeds, e.g., it does not
shift down if the engine speed is too high.
The selected gear is briefly displayed in the in‐
strument cluster, followed by the current gear.
Displays in the instrument cluster
The transmission position is displayed and the
engaged gear, such as M4, is displayed in
manual mode.
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.

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

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
