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.
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.
Coolant level
Checking
There are yellow minimum and maximum
marks in the coolant reservoir.
General information
Coolant consists of water and coolant addi-
tive.
1. Let the engine cool down.
2. Open the hood, refer to page 273.
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.
3. Turn the lid of the coolant reservoir
slightly counterclockwise to allow any
excess pressure to dissipate, then open
it.
Safety information
4. Open the coolant reservoir lid.
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.
