Important Notes:
BMW M Motorsport Customer Racing Vehicles.
Your BMW M Motorsport Customer Racing Vehicle has been designed for motorsport use and therefore
significantly differs from road legal production vehicles. These Important Notes provide you with essential
information regarding the safety and security of your vehicle, recommended usage scenarios and vehicle
characteristics.
Safety and security
Not for use on public roads
•The vehicle is not approved for use on public roads and does not comply with the locally
applicable road approval regulations.
•The vehicle has been designed for specific motorsport usage scenarios only, please see below
“Usage scenarios” for further details.
Driving characteristics and driver skills
•Driving characteristics of the vehicle significantly differ from road legal production vehicles. BMW
recommends special race training, ideally a racing license, for drivers and continuous training and
education during the whole holding and usage period of the vehicle. Otherwise the driver and third
parties can be exposed to significant risks.
•BMW recommends to register with BMW M Motorsport (https://specials.bmw-
motorsport.com/kundensport/) in order to receive vehicle specific safety-related information.
Observance of applicable law
•The operation of the vehicle, as well as all work on the vehicle, might be subject to special legal
requirements, in particular concerning safety and security, under the (locally) applicable law.
•Such requirements may especially derive from guidelines and regulations of the local (traffic or
sporting) authorities, health protection regulations, accident protection regulations and environmental
protection regulations.
•The assessment and observance of such guidelines and regulations as well as any other applicable legal
provisions is your exclusive responsibility.
IMPORTANT NOTES.
Repair and maintenance instructions
•BMW recommends that all repair, maintenance and adjustment work is carried out by official BMW M
Motorsport dealers or equally qualified professional mechanics. Any attempt to carry out repair, maintenance
or adjustment work without appropriate training, tools and equipment may result in serious injuries
(including death) to yourself or others. In addition, vehicle damage or malfunctions of the vehicle can occur.
•The (functional) safety and security of the vehicle is only ensured if the instructions in the manual are strictly
followed. It is your responsibility to read and understand the information in the manual. If you have any
questions about the content of the manual, please contact your BMW M Motorsport dealer or send an e-mail
to: technical-supp[email protected].
•The vehicle design is geared towards lightweight construction. As a result the vehicle has a reduced durability
compared to road legal production vehicles. For this reason, it is your responsibility to strictly follow the
vehicle manual instructions regarding handling, service and maintenance intervals of the vehicle and running
times of the components.
Safety equipment
•The vehicle is equipped with built-in safety equipment such as safety roll cage, fire extinguishing equipment,
safety belts, safety tank and certified racing seat in order to protect the driver. Some of these safety devices
have a limited durability and must be checked regularly and replaced if necessary (see user manual for further
details).
•After an accident and/or potential damage to the installed safety equipment such as the safety roll cage, fire
extinguishing equipment, safety belts, safety tank and certified racing seat, the vehicle must be checked for
damage by a recognized technical scrutineer, a BMW M Motorsport dealer or an equally qualified
professional mechanic and may only be reused after repair and release by the person performing the check
and repair.
•In order for the safety equipment in the vehicle to be fully effective, BMW recommends that the driver also
wears up-to-date (FIA) certified safety equipment, consisting of helmet, shoes, gloves, head and neck support
(HANS) system and fireproof racing suit and underwear.
•In addition to the above mentioned safety equipment, there are various components of the vehicle (see user
manual) which must be in fully functioning condition for safe operation of the vehicle. Components must be
checked for damage after accidents and atypical driving manoeuvres and, if necessary, be serviced or
replaced.

BMW M2 CS RACING 2020 I DRIVER MANUAL I BMW M MOTORSPORT I V02 I AUGUST 2023 Page 5
Roll cage –special requirements
•The roll cage is firmly welded into the body. Any modifications to the roll cage will likely result in non-
registration or disqualification of the vehicle.
•In the event of an accident, the roll cage must be inspected and approved by a technical scrutineer or an
independent expert. A damaged roll cage will result in reduced occupant protection.
•BMW recommends replacing a damaged cage with a new one. Cage repairs should only be carried out by a
certified cage manufacturer. Please pay particular attention to the cage certificate including instructions,
which are enclosed with the vehicle.
Usage scenarios

Vehicle characteristics
As described in the chapter “Safety and Security”, the vehicle deviates significantly from road legal production
vehicles. The below described characteristics of the vehicle may occur due to the specific purpose of use of the
vehicle and its corresponding design, but do not constitute a defect:
•Corrosion
To optimize performance and weight, corrosion protection measures are not fully applied. This can result in
corrosion damage to body components, paintwork, chassis and drivetrain components. For this reason it is
strongly recommended to store the vehicle in a dry place. Should moisture penetrate into the vehicle, it is
recommended to remove the moisture immediately.
•Brakes
The brake system is one of the most heavily stressed components in motorsport vehicles. Explicit reference
is made to the instructions in the vehicle manual for handling of the brake system, in particular the run-in
instructions must be respected. Non-compliance can result in significantly increased wear and tear and/or
damage to the brake system. Due to the performance design of the brake system, acoustic abnormalities,
such as brake squeal, are not considered a defect.
•Vehicle battery
The specific electric motorsport components significantly increase the quiescent current level. If the vehicle
is not used for a longer period of time, it is recommended to disconnect the vehicle from the power supply
via the main battery switch. In case of shorter interruptions, it is recommended to charge the battery via an
external power supply.
•Vehicle glazing
To optimize performance and weight, Makrolon ®plastic car windows are used to some extent. These may
show optical distortions due to their nature. They are also less scratch-resistant than conventional glass car
windows.
IMPORTANT NOTES.

PSL: Pressing PSL activates the Pit Speed limiter. The Limiter can be operated in any driving dynamics mode. The limiter target speed can be selected via the SEPP mode. There are two different PSL limits that can be
set in the SEPP mode via the DSC switch (Limit 1 - low) / FDS switch (Limit 2 - high). Push the selected switch up or down to increase/decrease the PSL limit. In the Dash, the respective limit is displayed in SEPP mode
under OIL (Limit 1) and WAT (Limit 2). Only the limiter is active, which is in the catch-speed limit, when the PSL button is pressed. For example: If limiter 1 is set to 60 km/h and Limiter 2 is set to 120 km/h, Limiter 1 is
active at a speed up to 90 km/h. Limiter 2 is active from 90 km/h.
