warning light should come on briefly
when ignition is placed in ON/RUN.
If it does not come on, then have it
fixed so it will be ready to warn if
there is a problem.
If this light comes on, there is a
problem with a system on the
vehicle that is causing the park
brake system to work at a reduced level. The vehicle can still be driven,
but should be taken to a dealer/
retailer as soon as possible. See
Parking Brake
on page 8‑32for
more information.

Antilock Brake System
(ABS) Warning Light
This light comes on briefly when the
engine is started.
If the light does not come on, 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 off the vehicle. Then start
the engine again to reset the
system. If the ABS light stays on,
or comes on again while driving, the
vehicle needs service. A chime may
also sound when the light comes on
steady.
If the ABS light is the only light on,
the vehicle has regular brakes, but
the antilock brakes are not
functioning.
If both lights are on, the vehicle's
antilock brakes are not functioning
and there is a problem with the
regular brakes. See your dealer/
retailer for service.

9-14 Vehicle Care
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A Change Engine Oil
Soon message comes on. See
Engine Oil Messages
on
page 4‑35. Change the oil as soon
as possible within the next 1 000 km
(600 miles). It is possible that,
if driving under the best conditions,
the oil life system might not indicate
that an oil change is necessary for
over a year. However, the engine oil
and filter must be changed at least
once a year and at this time the
system must be reset. Your dealer/
retailer has trained service people
who will perform this work using
genuine parts and reset the system.
It is also important to check the oil
regularly and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 miles)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Turn the key to ON/RUN with the engine off.
2. Press the DIC menu button on the turn signal lever to scroll
through the menu items on the
DIC screen.
3. Press the set button to clear the Change Engine Oil Soon
message and/or restore the
Remaining Oil Life 100%
message.
4. Turn the key to LOCK/OFF.
The system is reset when the
Change Engine Oil Soon message
is off and the Remaining Oil Life
100% message is is displayed.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer's warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your
own oil, be sure to drain all the oil
from the filter before disposal. Never
dispose of oil by putting it in the
trash, pouring it on the ground, into
sewers, or into streams or bodies of
water. Recycle it by taking it to a
place that collects used oil.
