Electronic throttle control:
Illuminates when the engine has defaulted to a “limp-home” operation.
Report the fault to a dealer at the earliest opportunity.
Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the on position
when the engine is not running, or in a position between on and start, or
by applying the parking brake when the ignition is turned to the on
position. If the brake system warning light does not illuminate at this
time, seek service immediately from your authorized dealer. Illumination
after releasing the parking brake indicates low brake fluid level and the
brake system should be inspected immediately by your authorized dealer.
WARNING:Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the vehicle.
Have the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
Brake reserve system warning (if equipped):Illuminates to indicate
normal Hydromax booster reserve system activation when the engine is
off and the service brake pedal is applied.
This light may also illuminate
momentarily if the engine is running
and the driver turns the steering
wheel fully in one direction while
braking.
If the light remains on while the engine is running, this indicates
inadequate hydraulic booster pressure or reserve pump system failure.
Stop the vehicle as soon as possible and seek service immediately by
your authorized dealer.

System warnings
System warnings alert you to possible problems or malfunctions in your
vehicle’s operating systems.
In the event of a multiple warning situation, the message center will
cycle the display to show all warnings by displaying each one for four
seconds.
The message center will display the last selected feature if there are no
more warning messages. This allows you to use the full functionality of
the message center after you acknowledge the warning by pressing the
RESET control and clearing the warning message.
Warning messages that have been reset are divided into two categories:
•They will not disappear until a condition is changed.
•They will reappear on the display 10 minutes from the reset.
This acts as a reminder that these warning conditions still exist within
the vehicle.

WARNING:If you smell exhaust fumes inside your vehicle, have
your dealer inspect your vehicle immediately. Do not drive if you
smell exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped in an open area for
long periods of time, open the windows at least one inch (2.5 cm).
Adjust the heating or air conditioning (if equipped) to bring in fresh air.
Improve vehicle ventilation by keeping all air inlet vents clear of snow,
leaves and other debris.
BRAKES
Your service brakes are self-adjusting. Refer to thescheduled
maintenance informationfor scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle’s brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a “metal-to-metal,” “continuous grinding” or
“continuous squeal” sound is present while braking, the brake linings
may be worn-out and should be inspected by an authorized dealer.
Refer toBrake system warning
lightin theInstrument Cluster
chapter for information on the brake
system warning light.
WARNING:If you are driving down a long or steep hill, shift to
a lower gear. Do not apply your brakes continuously, as they may
overheat and become less effective.
Hydraulic brake booster system (Hydroboost or Hydromax)
The Hydroboost and Hydromax systems receive fluid pressure from the
power steering pump to provide power assist during braking.
The Hydromax booster receives backup pressure from the reserve
system electric pump whenever the fluid in the power steering system is

not flowing. When the engine is OFF, the pump will turn on if the brake
pedal is applied, or if the ignition is turned to the ON position.
The sound of the pump operating may be heard by the driver, but this is
a normal characteristic of the system.
The reserve system provides reduced braking power, so the vehicle
should be operated under these conditions with caution, and only to seek
service repair and remove the vehicle from the roadway.
For Hydromax-equipped vehicles operating under normal
conditions,the noise of the fluid flowing through the booster may be
heard whenever the brake is applied. This condition is normal. Vehicle
service is not required.
If braking performance or pedal response becomes very poor, even when
the pedal is strongly depressed, it may indicate the presence of air in the
hydraulic system or leakage of fluid. Stop the vehicle safely as soon as
possible and seek service immediately.
Anti-lock brake system (ABS)
On vehicles equipped with an anti-lock braking system (ABS), a noise
from the hydraulic pump motor and pulsation in the pedal may be
observed during ABS braking events. Pedal pulsation coupled with noise
while braking under panic conditions or on loose gravel, bumps, wet or
snowy roads is normal and indicates proper functioning of the vehicle’s
anti-lock brake system. The ABS performs a self-check after you start
the engine and begin to drive away. A brief mechanical noise may be
heard during this test. This is normal. If a malfunction is found, the ABS
warning light will come on. If the vehicle has continuous vibration or
shudder in the steering wheel while braking, the vehicle should be
inspected by an authorized dealer.
The ABS operates by detecting the
onset of wheel lockup during brake
applications and compensates for
this tendency. The wheels are
prevented from locking even when
the brakes are firmly applied. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during hard braking with loss of front braking
traction.
