In the engine compartment

Checking the coolant level

The engine must be at ambient tempera-
ture

Open the cap of the expansion tank by turn-
ing it slightly counterclockwise to allow
accumulated pressure to escape, then
open completely

The coolant level is correct when the upper
end of the red float is at least even with the
upper edge of the filler neck but no more
than 3/4 in/2 cm above it, that is up to the
second mark on the float. Refer also to the
schematic diagram next to the filler neck

Slowly add coolant, if necessary, until the
correct level is reached; do not overfill

Turn the cap clockwise until it is tightly
closed

Have the cause for the coolant loss
removed as soon as possible.

Brake system

Malfunction

Brake fluid

The warning lamp lights up although
the parking brake is not engaged:
Stop the vehicle immediately.

The brake fluid level in the reservoir is too low.
At the same time, you may notice that brake
pedal travel is longer. Have the system checked
as soon as possible.

If you continue driving, extended pedal
travel may be necessary and braking dis-

tances may be significantly longer. Be sure to
adapt your driving style accordingly.

Indication of the above-described mal-
function in Canadian models.

Brake pads

The warning lamp lights up. The brake
pads have worn down to the minimum
safe limit. Have the brake pads

replaced as soon as possible.

For your own safety: use only brake pads
which BMW has approved for your spe-

cific vehicle model. BMW cannot evaluate non-
approved brake pads to determine if they are
suitable for use, and therefore cannot guaran-
tee the operating safety of the vehicle in the
event of their use.
