4Power steering (if equipped)Power steering uses energy from the
engine to assist you in steering the vehi-
cle. If the engine is off or if the power
steering system becomes inoperative,
the vehicle may still be steered, but it will
require increased steering effort.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power steer-
ing checked by an authorized Kia dealer.✽ ✽
NOTICE• Never hold the steering wheel against
a stop (extreme right or left turn) for
more than 5 seconds with the engine
running. Holding the steering wheel
for more than 5 seconds in either posi-
tion may cause damage to the power
steering pump.
• If the power steering drive belt breaks or if the power steering pump mal-
functions, the steering effort will
greatly increase.
✽ ✽ NOTICEIf the vehicle is parked for extended
periods outside in cold weather (below -
10 °C/14 °F), the power steering may
require increased effort when the engine
is first started. This is caused by
increased fluid viscosity due to the cold
weather and does not indicate a mal-
function.
When this happens, increase the engine
RPM by depressing the accelerator until
the RPM reaches 1,500 rpm then release
or let the engine idle for two or three
minutes to warm up the fluid.
Tilt and telescopic steering
(if equipped)A tilt and telescopic steering wheel
allows you to adjust the steering wheel
before you drive. You can also raise it to
the highest level to give your legs more
room when you exit and enter the vehi-
cle.
The steering wheel should be positioned
so that it is comfortable for you to drive,
while permitting you to see the instru-
ment panel warning lights and gauges.
STEERING WHEEL

Never adjust the angle of steering
wheel while driving. You may lose
