2015 BMW Z4 engine overheat

Radio ready stateIndividual electrical consumers can operate.
The time and the external temperature are dis‐
played in the instrument cluster.
Radio ready state is switched off automatically:▷When the remote control is removed from
the ignition lock.▷In cars with Comfort Access, by touching
the surface above the door lock, locking,
refer to page 40.
Ignition on
All electrical consumers can operate. The od‐
ometer and trip odometer are displayed in the
instrument cluster.
To save battery power when the engine is off,
switch off the ignition and any unnecessary
electronic systems/power consumers.
Radio ready state and ignition off
All indicator and warning lamps as well as dis‐
plays in the instrument cluster go out.
Sport automatic transmission
In certain situations, transmission position P is
engaged automatically. To make it possible for
the vehicle to roll, such as in an automatic car
wash, follow the instructions in Car washes, re‐
fer to page 257.
Starting the engine Enclosed areas
Do not let the engine run in enclosed
areas; otherwise, breathing of exhaust fumes
may lead to loss of consciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless but highly toxic
gas.◀
Unattended vehicle
Do not leave the car unattended with the
engine running; otherwise, it presents a poten‐
tial source of danger.
Before leaving the car with the engine running,
set the parking brake and place the transmis‐
sion in position P or neutral to prevent the car
from moving.◀
Frequent starting in quick succession
Avoid repeated futile attempts at starting
the car and avoid starting the car frequently in
quick succession. Otherwise, the fuel is not
burned or is inadequately burned, and there is
the danger of overheating and damaging the
catalytic converter.◀
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate engine speeds.
Manual transmission
Remote control in the ignition lock or, with
Comfort Access, inside the vehicle, refer to
page 39.
1.Depress the brake pedal.2.Depress the clutch pedal.3.Press the Start/Stop button.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.

▷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.

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
