Brake disc corrosion
Brake disc corrosion and contamination of the
brake pads are favored by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion will built up when the maximum
pressure applied to the brake pads during
braking is not reached - thus discs don't get
cleaned.
Corrosion buildup on the brake discs will cause
a pulsating effect on the brakes in their re‐
sponse - generally that cannot be corrected.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops collecting under‐
neath the vehicle.
These traces of water under the vehicle are
normal.

Increase rangeGeneral informationThe vehicle contains comprehensive technolo‐
gies for reducing the energy consumption and
for maximizing the range.
The range depends on a number of different
factors.
The implementation of certain measures, driv‐
ing style and regular maintenance can increase
range and thereby also reduce the environ‐
mental impact.
Remove unnecessary cargo
Additional weight reduces the range.
Remove attached parts
following use
Attached parts on the vehicle impair the aero‐ dynamics and increase the energy consump‐
tion.
Close the windows and glass
sunroof
Driving with the glass sunroof and windows
open results in increased air resistance and
thereby reduces the range.
Tires
General information
Tires can affect energy consumption in various
ways, for instance energy consumption can be
influenced by tire size.Check the tire inflation pressure
regularly
Check and, if needed, correct the tire inflationpressure at least twice a month and before
starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises energy consumption
and tire wear.
Standing air conditioning Run advance climate control, refer to
page 133, in the vehicle during charging if pos‐
sible before driving off.
Heating and cooling operations are very en‐
ergy intensive and substantially reduce the
electric range.
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 proactively reduces en‐
ergy consumption.
Longer braking procedures result in more effi‐
cient charging of the high-voltage battery via
energy recovery from braking.
Use accelerator pedal for
deceleration and coasting
When approaching a red light, use accelerator
pedal for decelerating.
For going downhill use coasting function; for
this purpose, press accelerator pedal just
enough that the vehicle rolls.Seite 154Driving tipsIncrease range154

Switch off any functions that
are not currently needed
Functions such as the rear window defroster
require a lot of energy and reduce the range,
especially in city and stop-and-go traffic.
Reel off these functions if they are not needed.
The ECO PRO and ECO PRO+ driving pro‐
grams support the energy-conserving use of
comfort features. They automatically perform a
partial or complete deactivation of these func‐
tions.
Have maintenance carried
out
Have vehicles maintained regularly to achieve
optimal vehicle efficiency and operating life.
The maintenance should be carried out by
your service center.
Also note the BMW Maintenance System, refer
to page 188.
ECO PRO and ECO PRO+ The concept
ECO PRO and ECO PRO+ support an efficient
driving style. To this end, the control of the
drive is optimized for moderate acceleration,
and adapted to lighting and comfort features,
such as climate control output. Some vehicle
functions cannot be used during activated
drive mode ECO PRO and ECO PRO+.
In addition, context-sensitive instructions can
be displayed that assist in driving efficiently.
At a glance With ECO PRO and ECO PRO+ different set‐
tings are made in the respective mode.ECO PRO▷Reduce heat output or heating cycle for ex‐
terior mirror, rear window and seat heating.▷What reduces the the cooling and heating

car.
With a set departure time, the vehicle is cli‐
mate controlled during the charging process
when climate control is set. Climate control
output is reduced during the trip. This in‐
creases the range.
The following settings are possible at depar‐
ture time:
▷Climate control at departure time.▷Planning a one-time departure time.▷Planning of up to three regular departure
times per day of the week.If drive readiness is switched off, changes can
be made on the Control Display. Departure
time can only be changed once. Scheduled de‐
parture times are not adjusted. Settings for cli‐

General information
In addition to the high-voltage battery, the ve‐
hicle has a 12 volt vehicle battery, which is re‐
quired for operation of the onboard electron‐
ics.
If the high-voltage battery and the vehicle bat‐
tery are discharged, it is not possible to oper‐
ate the vehicle.
Place vehicle in service To place the vehicle in service, charge as
usual.
If there is no possibility of charging on site,
contact the service center.

Uniform Tire Quality GradingQuality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section width.
For example: Treadwear 200; Traction AA;
Temperature A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to Fed‐
eral Safety Requirements in addition to these
grades.
TreadwearThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov‐
ernment test course. For example, a tire
graded 150 would wear one and one-half, 1 g,
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and may depart signifi‐
cantly from the norm due to variations in driv‐
ing habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to lowest,
are AA, A, B, and C.
Those grades represent the tire's ability to
stop on wet pavement as measured under
controlled conditions on specified government
test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction tests,
and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the ma‐
terial of the tire to degenerate and reduce tire
life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds
to a level of performance which all passenger
car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades Band
A represent higher levels of performance on
the laboratory test wheel than the minimum re‐
quired by law.
Temperature grade for this tire
The temperature grade for this tire is es‐
tablished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
If necessary, have the vehicle towed.◀
M+S
Winter and all-season tires with better cold
weather performance than summer tires.
Tire tread
Summer tires
Do not drive with a tire tread depth of less than
0.12 in/3 mm.
There is an increased danger of hydroplaning if
the tire tread depth is less than 0.12 in/3 mm.
Winter tires
Do not drive with a tire tread depth of less than
0.16 in/4 mm.
Below a tread depth of 0.16 in/4 mm, tires are
less suitable for winter operation.Seite 175Wheels and tiresMobility175
