occurs in the following situations:▷The high-voltage battery has an insuffi‐
cient charge.▷The vehicle has a flat tire.▷When activating cruise control in TRAC‐
TION or DSC OFF mode.
DTC Dynamic Traction
Control
The concept The DTC system is a version of the DSC where
forward momentum is optimized.
The system ensures maximum headway on
special road conditions or loose road surfaces,
e.g., unplowed snowy roads, but with some‐
what limited driving stability.
Activating the Dynamic Traction Control DTC
provides maximum traction. Driving stability is
limited during acceleration and when driving in
curves.
Therefore drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
▷When driving in slush or on uncleared,
snow-covered roads.▷When freeing vehicle from deep snow or
driving off from loose grounds.▷When driving with snow chains.Seite 110ControlsDriving stability control systems110

With the BMW i Remote App, refer to
page 128, the standing air conditioning can be
switched on.
The system switches off automatically after a
certain period of time.
If stationary climate control is used during the
charging process, less air conditioning ca‐
pacity will be required while driving. This opti‐
mizes the range.
Functional requirements▷When the departure time is preselected:
depends on internal, external and set tem‐
perature.▷Direct operation via iDrive: any external

Things to remember when drivingVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Breaking-in period General information
Moving parts need time to adjust to one an‐
other (break-in time).
The following instructions will help accomplish
a long vehicle life and good efficiency.
During break-in, do not use the Launch Con‐
trol, refer to page 73.
Engine, transmission, and axle drive
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road
speed:▷For gasoline engine 4,500 rpm and
100 mph/160 km/h.
Avoid full load or kickdown under all circum‐
stances.
From 1,200 miles/2,000 km The engine and vehicle speed can gradually be
increased.
Tires
Tire traction is not optimal due to manufactur‐
ing circumstances when tires are brand-new;
they achieve their full traction potential after a
break-in time.
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 optimal per‐
formance between brake discs and brake
pads. Drive moderately during this break-in pe‐
riod.
Following part replacement
The same break-in procedures should be ob‐
served if any of the components above-men‐
tioned have to be renewed in the course of the
vehicle's operating life.
Using eDRIVE efficiently The concept
eDRIVE operates automatically. Proactive driv‐
ing utilizes energy consumption and energy re‐
covery optimally. Energy recovery is used to
charge the high-voltage battery. It is important
for the supply of electrical components and
thus a prerequisite for an extensive range. En‐
ergy consumption and recovery depend very
much, among other things, on your driving
style.
Optimizing driving style
Performance display The driving style can be optimized using the
performance display in ECO PRO mode.Seite 138Driving tipsThings to remember when driving138
Online Edition for Part no. 01 40 2 960 891 - II/15

The driving style is efficient as long as the ac‐
celerator pedal pointer is within the lower
range highlighted in blue during acceleration
and deceleration.
The energy recovery occurs during coasting
and braking and is displayed in the perform‐
ance display by the accelerator pedal indicator.
The accelerator pedal pointer is within the
CHARGE range.
Efficient energy recovery:
▷The accelerator pedal moves to the left
within the blue range of the CHARGE dis‐
play, arrow 1.▷The energy use while driving can be opti‐
mized by efficient acceleration.
Efficient acceleration:
▷The accelerator pedal moves to the right
within the blue range of the eDRIVE dis‐
play, arrow 2.▷Use deceleration during coasting as often
as possible for energy recovery.
Brake according to traffic and circum‐
stances
Brake in accordance with the traffic conditions,
or there is the risk of accident.◀
Using drive modes and assistance
systems
Max eDRIVE
Max eDRIVE, refer to page 64, forces electric
driving. Electric driving is especially efficient
for short distances, low to medium speeds and
in stop-and-go traffic.
SAVE battery
SAVE Battery, refer to page 64, conserves the
electric range for a later point in time. In this
case, the vehicle is driven primarily by the
combustion engine.
ECO PRO ECO PRO, refer to page 145, supports a driv‐
ing style that saves on fuel consumption. For
this purpose, the engine control and comfort
features, e. g. the climate control output, are
adjusted.
Discharge of the high-voltage battery Longer idle periods, refer to page 190, can re‐
duce the charging state of the high-voltage
battery.
Do not allow the vehicle to sit idle for ex‐
tended periods with a low charging state
Before storing the vehicle for an extended pe‐
riod, check the battery charge indicator to en‐
sure that the high-voltage battery is fully
charged. During the idle period, connect the
vehicle to a charging station at a suitable
charging location. If necessary, the high-volt‐
age battery will be charged automatically.
Make sure that the charging process takes
place. Regularly check the charging state.
Don't allow battery charge status to drop too
low - it will damage the battery.◀
