CAUTION: (Continued)
If the brake system warning light is
not on, you still have brakes, but the
supplemental brake assist system on
vehicles with rear disc brakes may not
operate properly. In the event of a vacuum
loss, you may not have vacuum power
assist for braking. The brake pedal will be
harder to push and it will take longer to
stop. If you continue to drive with this
message displayed it can lead to a crash.
Have the brake system serviced as soon
as possible.
If your vehicle has vacuum assist power brakes,
this message will be displayed on the DIC
when there is a problem with the Supplemental
Brake Assist system. If the message is displayed
immediately after starting the vehicle or the
message appears while driving, the Supplemental
Brake Assist system needs service. See your
dealer. See Brake System Warning Light on
page 252 for additional information.
