Coolant
Warning lamp
The warning lamp lights up: coolant
level is too low; top off at the next
opportunity.
Do not open 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 suit-
able for your BMW. Ask your BMW Sports
Activity Vehicle Center for suitable additives.
Only use suitable additives; otherwise,
engine damage may result. The additives
are harmful to your health, so follow the instruc-
tions on the containers.
<
Always observe all applicable environ-
mental laws and regulations when dis-
posing of used coolant additives. <
Checking coolant level
1. Allow engine to cool.
2. Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.
3. The coolant level is correct when it is
between the MIN and MAX marks, also refer
to illustration next to filler neck.
4. If the coolant is low, slowly add coolant up to
the specified level – do not overfill.
5. Screw on the cap and tighten snugly.
6. Have the reason for the coolant loss cor-
rected as soon as possible.
Brake system
Malfunction
Brake fluid
The warning lamp lights up red despite
the handbrake being released.
The brake fluid in the reservoir has
fallen to below the minimum level. At the same
time, a considerably longer brake pedal travel
may be noticeable. Have the system checked
immediately.
During continued driving, increased brake
pedal travel may be necessary, and con-
siderably longer braking distances may result.
Please adapt your driving style accordingly.
