engine overheat BMW Z4 SDRIVE35I 2014 Owners Manual

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 37.
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 255.
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 37.
1.Depress the brake pedal.2.Press on the clutch and shift to neutral.3.Press the Start/Stop button.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.

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 68.▷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.
Transmission positionsP R N D M/S + –
Displays in the instrument cluster
The gear position and the engaged gear, such
as M4, are displayed.
Engaging transmission positions N, D,
R
▷Transmission position P can only be disen‐
gaged if the engine is running.▷Before moving the lever away from P or N
with the vehicle stationary, depress the
brake; otherwise, the transmission will not
shift.
Press on the brake pedal until you start
driving
To prevent the vehicle from creeping after you
select a driving position, maintain pressure on
the brake pedal until you are ready to start.◀
Briefly push the selector lever in the desired di‐
rection, beyond a resistance point if necessary.
When shifting out of P or into R, press button 1
at the same time.
The engaged transmission position is also dis‐
played on the selector lever.
When you release the selector lever, it returns
to its center position.

Ensure that the floor mats are securely fas‐
tened again when they are returned after being
removed, 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, 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 64.
Downshifting in manual mode of the 7-gear
Sport automatic transmission with dual clutch,
refer to page 67.
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
inside 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.◀
