2014 BMW Z4 SDRIVE35I inflation pressure

Close both windows
An open window causes higher air resistance
and thus increases fuel consumption.
Tires
General information
Tires can have varying effects on fuel con‐
sumption; for example, fuel consumption can
be influenced by the tire size.
Check the tire inflation pressure
regularly
Check and, if necessary, correct the tire infla‐
tion pressure, refer to page 227, at least twice
a month and before starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away without delay Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate engine speeds.
This is the fastest way for the cold engine to
reach its operating temperature.
Look well ahead when driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐ cle driving ahead of you.
Driving smoothly and looking ahead reduces
fuel consumption.
Avoid high engine speeds
Use 1st gear to get the vehicle in motion. Be‐
ginning with 2nd gear, accelerate rapidly.
When accelerating, shift up before reaching high engine speeds.
When you reach the desired speed, shift into
the highest applicable gear and drive with the
engine speed as low as possible and at a con‐
stant speed.As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Use coasting conditions
When approaching a red light, take your foot
off the accelerator and coast to a halt in the
highest applicable gear.
On a downhill slope, take your foot off the ac‐
celerator and coast in a suitable gear.
The flow of fuel is interrupted while coasting.
Switch off the engine during longer
stops
Switch off the engine during longer stops, e.g.,
at traffic lights, railroad crossings or in traffic
congestion.
Automatic Engine Start/Stop Function
The Automatic Engine Start/Stop Function au‐
tomatically switches the engine off during a
stop.
If the engine is stopped and then started again,
fuel consumption and emissions drop com‐
pared to an engine that runs permanently.
Stopping the engine even for just a few sec‐
onds can result in savings.
Use of this system can cause premature wear
on certain vehicle components.
In addition, fuel consumption depends on
other factors as well, such as driving style, road
conditions, maintenance, and environmental
factors.
Additional information on the Automatic En‐
gine Start/Stop Function, refer to page 57.
Switch off any functions that are not
currently needed
Functions such as the automatic climate con‐
trol require a large amount of energy and con‐
sume additional fuel, especially in city and
stop-and-go traffic.
Therefore, switch off these functions if they
are not actually needed.Seite 133Things to remember when drivingDriving tips133

Wheels and tiresVehicle 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.
Tire inflation pressure
Information for your safety
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres‐
sure.
Check the tire inflation pressure regularly
Regularly check the tire inflation pres‐
sure and correct it as needed: at least twice a
month and before a long trip. If you fail to ob‐
serve this precaution, you may be driving on
tires with incorrect tire pressures, a condition
that may not only compromise your vehicle's
driving stability, but also lead to tire damage
and the risk of an accident.◀
Checking the pressure Only check the tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle
has been parked for at least 2 hours. When the
tires are warm, the tire inflation pressure is
higher.
After correcting the tire inflation pressure, rein‐
itialize the Flat Tire Monitor, refer to page 92.
After correcting the tire inflation pressure, re‐
set the Tire Pressure Monitor, refer to page 95.Pressure specifications
The tables below provide all the correct infla‐
tion pressures for the specified tire sizes at
ambient temperature.
The inflation pressures apply to the tire sizes
approved and tire brands recommended by
BMW; a list of these is available from your
service center.
For correct identification of the right tire infla‐
tion pressures, observe the following:▷Tire sizes of your vehicle.▷Maximum allowable driving speed.
Tire inflation pressures for driving up
to 100 mph or 160 km/h
For normal driving up to 100 mph/160 km/h,
adjust pressures to the respective tire inflation
pressures listed on the following pages in the
column for traveling speeds up to 100 mph/
160 km/h to achieve optimum driving comfort.
These tire inflation pressures can also be
found on the driver's side door pillar when the
driver's door is open.
Do not exceed the maximum permissible
speed
The maximum permissible speed for these tire
pressures is 100 mph/160 km/h Do not exceed
this speed; otherwise, tire damage and acci‐
dents could occur.◀

Tire inflation pressures for driving
above 100 mph or 160 km/h
Adjust the tire inflation pressures
To drive at maximum speeds in excess of
100 mph/160 km/h, adjust pressures to the re‐
spective tire inflation pressures listed on the
following pages in the column for travelingspeeds including those exceeding 100 mph or
160 km/h. Otherwise, tire damage and acci‐
dents could occur.◀
Observe all national and local maximum speed
limits; otherwise, violations of the laws could
occur.
