Coolant
Vehicle features and options
This chapter describes all standard, coun-
try-specific and optional equipment offered
with the series. It also describes features
and functions that are not necessarily avail-
able in the vehicle, e.g., due to the selected
options or country versions. This also ap-
plies to safety-related functions and sys-
tems. When using these functions and sys-
tems, the applicable laws and regulations
must be observed.
General information
Coolant consists of water and coolant addi-
tive.
Not all commercially available coolant addi-
tives are suitable for the vehicle. The vehi-
cle manufacturer recommends using coolant
with the BMW LC-18 specification. Do not
mix coolant additives of different colors.
Use a 50:50 mixing ratio of water to coolant
additive. Information on suitable coolant ad-
ditives can be provided by an authorized
service center or another qualified service
center or repair shop.
Safety information
Warning
With the engine hot and the cooling sys-
tem open, coolant can escape and lead to
scalding. There is a risk of injury. Only
open the cooling system with the engine
cooled down.
Warning
Additives are harmful and incorrect addi-
tives can damage the engine. There is a
risk of injury and risk of damage to prop-
erty. Do not allow additives to come into
contact with skin, eyes or articles of cloth-
ing. Use suitable additives only.
