If an airbag inflates or the vehicle
has been in a crash, the vehicle's
sensing system may command the
automatic hybrid battery disconnect
to open. When the battery
disconnect is open, the hybrid
battery will be off and the vehicle
will not start. The airbag readiness
light and/or SERVICE HYBRID
SYSTEM warning message may
come on in the Driver Information
Center (DIC). See “Airbag
Readiness Light” in the owner
manual and Driver Information
Center (DIC) on page 5‑11 for more
information. To operate the vehicle, the
automatic hybrid battery disconnect
must be reconnected by a qualified

English
The oil pressure gauge shows the
engine oil pressure in psi (pounds
per square inch) when the engine is
running. Canadian vehicles indicate
pressure in kPa (kilopascals).
Oil pressure should be 200 to
550 kPa (29 to 80 psi). In certain
situations, such as long extended
idles on hot days, it could read as
low as 105 kPa (15 psi) and still be
considered normal. A reading in the low pressure zone
may be caused by a dangerously
low oil level or some other problem
causing low oil pressure. Check the
oil as soon as possible.
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule for changing engine oil.
AUTO STOP
When the engine goes into
Automatic Engine Stop, the oil
pressure gauge drops to zero when
the tachometer is at the AUTO
STOP position. This is normal and
oil pressure returns to the normal
operating range once the engine
starts.
See Starting the Vehicle on
page 9‑2 for more information.
AUTO STOP displays in the Driver
Information Center (DIC) when the
vehicle speed is zero. See Driver
Information Center (DIC) on
page 5‑11 for more information.

Have it checked right away. If a
short distance must be driven with
the light on, be certain to turn off all
the accessories.
Brake System Warning
Light
With the ignition in ON/RUN, the
brake system warning light comes
on when the parking brake is set.
If the vehicle is driven with the
parking brake engaged, a chime
sounds when the vehicle speed is
greater than 8 km/h (5 mph).
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.If the warning light comes on and a
chime sounds there could be a
brake problem. Have the brake
system inspected right away.
This light also comes on due to low
brake fluid. See the owner manual
for more information.
MetricEnglish
This light should come on briefly
when the ignition key is turned to
ON/RUN. If it does not come on
then, have it fixed so it will be ready
to warn if there is a problem.
{WARNING
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
If the light comes on while driving,
pull off the road and stop carefully.
The pedal might be harder to push
or can go closer to the floor. It may
take longer to stop. If the light does
not go out, have the vehicle towed
for service. See General Towing
Information on page 9‑16.

Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light comes on
briefly when the engine is in
ON/RUN.
That is normal. If the light does not
come on then, have it fixed so it will
be ready to warn if there is a
problem.
If the ABS light stays on, turn the
ignition off, if the light comes on
while driving, stop as soon as it is
safely possible and turn the ignition
off. Then start the engine again to
reset the system. If the ABS light
still stays on, or comes on again
while driving, the vehicle needs
service. If the regular brake system
warning light is not on, the vehiclestill has brakes, but not antilock
brakes. If the regular brake system
warning light is also on, the vehicle
does not have antilock brakes and
there is a problem with the regular
brakes. See
Fuel Economy Gauge
on page 5‑6.
See Driver Information Center (DIC)
on page 5‑11 for all brake related
DIC messages.
StabiliTrak®OFF Light
For vehicles with StabiliTrak, this
warning light comes on briefly when
the ignition is in ON/RUN.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light goes off. If the light comes on and stays on
while driving, there could be a
problem with the StabiliTrak system
and the vehicle might need service.
When this warning light is on, the
StabiliTrak system is off and does
not limit wheel spin.
The light flashes if the system is
active and is working to assist the
driver with directional control of the
vehicle in difficult driving conditions.
See the owner manual for more
information.

Engine Oil Pressure Light
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule for changing engine oil.
This light comes on briefly as a
check it works, when the ignition is
in ON/RUN. If it does not, have the
vehicle serviced.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem.
During an AUTO STOP there is zero
oil pressure, but this light will not
come on.

may read BATTERY VOLTAGE
13 VOLTS. Your vehicle's charging
system regulates voltage based on
the state of the battery. The battery
voltage may fluctuate when viewing
this information on the DIC. This is
