General driving notes
Closing the trunk lid Drive with the trunk lid closed
Only drive with the tailgate closed; other‐
wise, in the event of an accident or braking and
evasive maneuvers, passengers and other traf‐
fic may be injured, and the vehicle may be
damaged. In addition, exhaust fumes may en‐
ter the vehicle interior.◀
If driving with the tailgate open cannot be avoided:▷If the hardtop is closed, close all windows.▷Greatly increase the air flow from the vents.▷Drive moderately.
Hot exhaust system
Hot exhaust system
High temperatures are generated in the
exhaust system.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that flammable materials, e. g. hay, leaves,
grass, etc. do not come in contact with the hot
exhaust system while driving, while in idle po‐
sition mode, or when parked. Such contact
could lead to a fire, resulting in an increased
risk of serious personal injury as well as prop‐
erty damage.
Do not touch hot exhaust pipes; otherwise,
there is a danger of getting burned.◀
Mobile communication devices in the
vehicle
Mobile communication devices in the ve‐
hicle
It is not recommended to use mobile phones,
such as mobile phones, in the vehicle interior
without a direct connection to an external aer‐
ial. Otherwise, the vehicle's electronics and
mobile communication devices can interfere
with each other. In addition, there is no assur‐
ance that the radiation generated during trans‐
mission will be conducted away from the vehi‐
cle interior.◀
Hydroplaning Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent hydroplaning.◀
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.
Driving through water Observe water level and speed
Do not exceed the maximum water level
and maximum speed; otherwise, the vehicle's
engine, the electrical systems and the trans‐
mission may be damaged.◀
Drive though calm water only and only if it is
not deeper than 9.8 inches/25 cm and at this
height, no faster than walking speed, up to 3 mph/5 km/h.
Braking safely
Your vehicle is equipped with ABS as a stand‐
ard feature.
Applying the brakes fully is the most effective
way of braking in situations needed.
Steering is still responsive. You can still avoid
any obstacles with a minimum of steering ef‐
fort.
The pulsing of the brake pedal indicates that
ABS is in its active mode.
In certain braking situations, the perforated
brake discs can cause functional problems.
However, this has no effect on the perform‐
ance and operational reliability of the brake.Seite 159Things to remember when drivingDriving tips159

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.Minimum tread depth
Wear indicators are distributed around the
tire's circumference and have the legally re‐
quired minimum height of 0.063 in/1.6 mm.
They are marked on the side of the tire with
TWI, Tread Wear Indicator.
Tire damage
General information
Inspect your tires often for damage, foreign
objects lodged in the tread, and tread wear.
Hints
Driving over rough or damaged road surfaces,
as well as debris, curbs and other obstacles
can cause serious damage to wheels, tires and
suspension parts. This is more likely to occur
with low-profile tires, which provide less cush‐
ioning between the wheel and the road. Be
careful to avoid road hazards and reduce your
speed, especially if your vehicle is equipped
with low-profile tires.
Indications of tire damage or other vehicle de‐
fects:
▷Unusual vibrations while driving.▷Unusual handling such as a strong ten‐
dency to pull to the left or right.
Damage can, e. g., be caused by driving over
curbs, road damage, or similar things.

necessarily available in your car, e. g., due tothe 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.
Note
The technical data and specifications in this
Owner's Manual are used as guidance values.
The vehicle-specific data can deviate from this,
for example, due to the selected special equip‐
ment, country version or country-specific
measurement method. Detailed values can befound in the approval documents, on informa‐
tion signs on the vehicle or can be obtained
from the service center.
The information in the vehicle documents al‐
ways has priority.
Dimensions
The dimensions can vary depending on the
model version, equipment or country-specific
measurement method.
The specified heights do not take into account
attached parts, for example, a roof antenna,roof racks or spoiler. The heights can deviate,
for example, due to the selected special equip‐
ment, tires, load and chassis version. BMW M4 ConvertibleWidth with mirrorsinches/mm79.3/2,014Width without mirrorsinches/mm73.6/1,870Heightinches/mm54.6/1,386Lengthinches/mm184.5/4,687Wheelbaseinches/mm110.7/2,812Smallest turning radius diam.ft/m40/12.2
