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.

Driving Information
Steering
This vehicle has On-Demand
Electric-Assist Power Steering
instead of conventional full-time
hydraulic power steering. It uses
electricity supplied by the same
battery which is re-charged by the
regenerative braking system.
Because the system is On-Demand
Electric-Assist, energy is used only
when the steering wheel is turned,
or when the steering gear is used to
help isolate the forces of rough
roads. This system does not use
power steering fluid, making it
maintenance-free.

Automatic Transmission
Fluid
When to Check and Change
Automatic Transmission Fluid
It is usually not necessary to check
the transmission fluid level. The
only reason for fluid loss is a
transmission leak or overheating the
transmission. If a small leak is
suspected, then use the following
checking procedures to check the
fluid level. However, if there is a
large leak, then it may be necessary
to have the vehicle towed to a
dealer service department and have
it repaired before driving the vehicle
further.
Notice:Use of the incorrect
automatic transmission fluid may
damage the vehicle, and the
damages may not be covered by
the vehicle warranty. Always use
the automatic transmission fluid
listed in Recommended Fluids
and Lubricants on page 11‑1. Change the fluid and filter at the
scheduled maintenance intervals
listed in Scheduled Maintenance.
Be sure to use the transmission fluid
listed in
Recommended Fluids and
Lubricants on page 11‑1.How to Check Automatic
Transmission Fluid
Notice: Too much or too
little fluid can damage the
transmission. Too much can
mean that some of the fluid could
come out and fall on hot engine
parts or exhaust system parts,
starting a fire. Too little fluid
could cause the transmission to
overheat. Be sure to get an
accurate reading if checking the
transmission fluid.
Before checking the fluid level,
prepare the vehicle as follows:
1. Start the engine and park the
vehicle on a level surface. Keep
the engine running.
2. Apply the parking brake and place the shift lever in P (Park). 3. With your foot on the brake
pedal, move the shift lever
through each gear range,
pausing for about three seconds
in each range. Then, move the
shift lever back to P (Park).
4. Allow the engine to idle (500–800 RPM) for at least
one minute. Slowly release the
brake pedal.
5. Keep the engine running and press the Trip/Fuel button or
trip odometer reset stem until
TRANS TEMP (Transmission
Temperature) displays on the
Driver Information Center (DIC).
6. Using the TRANS TEMP reading, determine and perform
the appropriate check
procedure. If the TRANS TEMP
reading is not within the required
temperature ranges, allow the
vehicle to cool, or operate the
vehicle until the appropriate
transmission fluid temperature is
reached.
