brake system checked immediately if the
brake warning lamp stays on. Do not add
brake fluid before checking the brake
system. Overfilling the brake fluid reservoir
can result in spilling brake fluid on hot en-
gine parts and the brake fluid catching fire.
You can be seriously burned.!
If you find that the brake fluid in the brake
fluid reservoir has fallen to the minimum mark or
below, have the brake system checked for brake
pad thickness and leaks.

Front passenger

See Oper. Manual

deactivated while driving even
though an adult or someone
larger than a small individual is
occupying the front passenger

may make the system sense a
decrease in weight.
Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Switch off the ignition (
page 315).

Have the front passenger vacate the seat and exit the vehicle.

Adjust the seat in a height position (
page 318).

objects such as books, briefcases etc. lodged underneath, behind or
around the seat). Such forces may cause the system to sense that an oc-
cupant of a lesser weight than actually present is on the front passenger
seat.

Keep the seat unoccupied, close the front passenger door and switch on
the ignition (
