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.

5. Add the pre‐mixed DEX‐COOL,available at your dealer, until the
coolant level is maintained at the
FULL COLD mark. This should
take no longer than two minutes
of hybrid cooling pump
operation.
If the level cannot be kept at the
FULL COLD level, the vehicle
may need service. See your
dealer.
6. Then replace the DMCM coolant
surge tank pressure cap. Be
sure the pressure cap is
hand-tight and fully seated. Notice:
Using tap water, cooling
system sealers or conditioners in
an attempt to stop coolant leaks
can damage the DMCM and
engine cooling systems. Never
use tap water, cooling system
sealers or conditioners in your
cooling system.
Power Steering Fluid
The vehicle has electric power
steering and does not use power
steering fluid.
Battery
This vehicle has a standard 12‐volt
battery and a high voltage hybrid
battery.
Refer to the replacement number on
the original battery label when a
new standard 12‐volt battery is
needed. Only a trained service technician
with the proper knowledge and tools
should inspect, test, or replace the
hybrid battery. See your dealer if the
hybrid battery needs service. The
dealer has information on how to
recycle the hybrid battery. There
is also information available at
http://www.recyclemybattery.com.
If an airbag inflates or the vehicle
has been in a crash, the vehicle's
sensing system might command the
automatic hybrid battery disconnect
to open. See
Replacing Airbag
System Parts After a Crash on
page 3‑2 for more information.
{DANGER
Battery posts, terminals, and
related accessories contain lead
and lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Wash hands after handling.
