Coolant

Do not add coolant to the cooling
system when the engine is hot.

Escaping coolant can cause burns.

Coolant consists of water and coolant
additive. Not all commercially available
additives are suitable for your BMW.
Ask your BMW Sport Activity Vehicle
center for suitable additives.

Only use suitable additives, as
otherwise engine damage may

result. The additives present a health
hazard.

Always observe all applicable
environmental rules and regula-

tions when disposing of used coolant
additives.

Checking coolant level

1. The engine must be at ambient tem-

perature

2. Start by turning the cap of the expan-

sion tank counter-clockwise. Pause
to allow any accumulated pressure to
escape, then open

3. The coolant level is correct when the

end of the red float is aligned with
the upper edge of the filler opening,
refer to the arrow in the illustration,
or max. 0.8 in/2 cm higher, i. e. up to
the mark on the float, refer also to the
schematic diagram, next to the cap

4. If the coolant is low, slowly add cool-

ant up to the specified level – do not
overfill

5. Twist closed the cap and tighten

firmly

6. Have the reason for the coolant loss

eliminated as soon as possible.
