Driving your vehicle
Power brakes
Your vehicle's brake system is
power-assisted by the electric
hydraulic pump.
In the event the brakes lose power
because of a brake control system
malfunction, unstable power supply
or some other reason, you can still
stop your vehicle by applying greater
force to the brake pedal than you
normally would. The stopping dis-
tance, however will be longer. Please
have the system checked as soon as
possible.
BRAKE SYSTEM
WARNING - Steep hillbraking
Avoid continuous application of
the brakes when descending a
long or steep hill by shifting to a
lower gear. Continuous brake
application will cause the
brakes to overheat and could
result in a temporary loss of
braking performance.
CAUTION - Brake pedal
Do not drive with your foot rest- ing on the brake pedal. This willcreate abnormally high braketemperatures which can causeexcessive brake lining and padwear.
WARNING
If the brake pedal does not
return to its normal position
when released, there may be a
malfunction in the brake sys-
tem. Take your vehicle to an
authorized Kia dealer and have
the system checked.
WARNING
Do not turn off the Hybrid sys-
tem while going down a hill. The
brake booster may not work
sufficiently and the braking dis-
tance may be longer.
CAUTION
Do not depress the brake pedalcontinuously without READYstatus. The battery may be dis-charged.

Driving your vehicle
Use high quality ethylene gly-
col coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in section 7. Never attempt to check
the Hybrid High Voltage Battery. The
level of charge in your battery can be
checked by an authorized Kia dealer
or a service station.
Change to "winter weight" oil
if necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
Kia dealer.
Check spark plugs and igni-
tion system
Inspect your spark plugs as
described in chapter 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.
Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized Kia dealer and most auto
parts outlets. Do not use engine
coolant or other types of anti-freeze
as these may damage the paint fin-
ish.
