or cannot be made ready for the test.
Brake System Warning Light
MetricEnglish
This light comes on briefly when the vehicle
is turned on to show that the light is
working. If it does not come on then, have
it fixed so it will be ready to warn you if

a brake problem. Have the brake system
inspected right away. This light may come
on if the brake fluid is low. See

pressure value shown on the Tire and
Loading Information label. SeeTire Pressure
0 292.
When the Light Flashes First and Then Is On
Steady
If the light flashes for about a minute and
then stays on, there may be a problem with
the TPMS. If the problem is not corrected,
the light will come on every time the
vehicle is started. See Tire Pressure Monitor
Operation 0295.Engine Oil Pressure Light
Caution
Driving the vehicle with low engine oil
pressure can damage the engine and the
