Driving your vehicle
Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event that the power-assisted
brakes lose power because of a stalled
engine or some other reason, you can
still stop your vehicle by applying greater
force to the brake pedal than you nor-
mally would. The stopping distance, how-
ever, will be longer.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied. Do
not pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when neces-
sary to maintain steering control on slip-
pery surfaces.
In the event of brake failure
If service brakes fail to operate while the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
BRAKE SYSTEM
(Continued)
When descending a long or steephill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brake
application will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
Wet brakes may impair the vehi- cle’s ability to sefely slow down;
the vehicle may also pull to one
side when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test
your brakes in this fashion after
driving through deep water. To
dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
Always, confirm the position of the brake and accelerator pedal
before driving. If you don't check
the position of the accelerator
and brake pedal before driving,
you may depress the accelerator
instead of the brake pedal. It may
cause a serious accident.
WARNING- Parking brake
Applying the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you must
use the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.
WARNING- Brakes
Do not drive with your foot rest-ing on the brake pedal. This will
create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increased
stopping distances.

Driving your vehicle
Vehicle stability management
(VSM) (if equipped)
This system provides further enhance-
ments to vehicle stability and steering
responses when a vehicle is driving on a
slippery road or a vehicle detected
changes in coefficient of friction between
right wheels and left wheels when brak-
ing.
VSM operation
When the VSM is in operation, ESC indi-
cator light ( ) blinks.
When the vehicle stability management
is operating properly, you can feel a slight
pulsation in the vehicle and/or abnormal
steering responses (EPS). This is only
the effect of brake and EPS control and
indicates nothing unusual.
The VSM does not operate when:
Driving on bank road such as gradientor incline
Driving rearward
ESC OFF indicator light ( ) remains on the instrument cluster
EPS indicator light remains on the instrument cluster
VSM operation off
If you press the ESC OFF button to turn
off the ESC, the VSM will also cancel and
the ESC OFF indicator light ( ) illumi-
nates.
To turn on the VSM, press the button
again. The ESC OFF indicator light goes
out.
Malfunction indicator
The VSM can be deactivated even if you
don’t cancel the VSM operation by press-
ing the ESC OFF button. It indicates that
a malfunction has been detected some-
where in the Electric Power Steering sys-
tem or VSM system. If the ESC indicator
light ( ) or EPS warning light remains
on, take your vehicle to an authorized
KIA dealer and have the system
checked.
✽ ✽ NOTICE
• The VSM is designed to function
above approximately 15 km/h (9 mph)
on curves.
• The VSM is designed to function above approximately 30 km/h (18
mph) when a vehicle is braking on a
split-mu road. The split-mu road is
made of surfaces which have different
friction forces.
WARNING
The Vehicle Stability Management
system is not a substitute for
safe driving practices but a sup-
plementary function only. It is the
responsibility of the driver to
always check the speed and the
distance to the vehicle ahead.
Always hold the steering wheel
firmly while driving.
Your vehicle is designed to acti- vate according to the driver’s
intention, even with installed
VSM. Always follow all the normal
precautions for driving at safe
speeds for the conditions –
including driving inclement
weather and on a slippery road.
Driving with varying tire or wheel sizes may cause the VSM system
to malfunction. When replacing
tires, make sure they are the
same size as your original tires.

Remember, your vehicle does not
require extended warm-up. After the
engine has started, allow the engine to
run for 10 to 20 seconds prior to plac-
ing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warm-up period.
Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in a very
high gear resulting in engine bucking. If
this happens, shift to a lower gear.
Over-revving is racing the engine
beyond its safe limit. This can be avoid-
ed by shifting at the recommended
speed. Use your air conditioning sparingly.
The air conditioning system is operat-
ed by engine power so your fuel econ-
omy is reduced when you use it.
Open windows at high speeds can reduce fuel economy.
Fuel economy is less in crosswinds and headwinds. To help offset some of
this loss, slow down when driving in
these conditions.
Keeping a vehicle in good operating con-
dition is important both for economy and
safety. Therefore, have an authorized KIA
dealer perform scheduled inspections
and maintenance.
WARNING - Engine off dur- ing motion
Never turn the engine off to coast
down hills or anytime the vehicle is
in motion. The power steering and
power brakes will not function
properly without the engine run-
ning. Instead, keep the engine on
and downshift to an appropriate
gear for engine braking effect. In
addition, turning off the ignition
while driving could engage the
steering wheel lock resulting in
loss of vehicle steering which
could cause serious injury or
death.

Maintenance
67
At least monthly:
Check the coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn sig-
nals and hazard warning flashers.
Check the inflation pressures of all tires including the spare.
At least twice a year (i.e., every Spring and Fall) :
Check the radiator, heater and air con- ditioning hoses for leaks or damage.
Check the windshield washer spray and wiper operation. Clean the wiper
blades with clean cloth dampened with
washer fluid.
Check the headlight alignment.
Check the muffler, exhaust pipes, shields and clamps.
Check the lap/shoulder belts for wear and function.
Check for worn tires and loose wheel lug nuts.
At least once a year :
Clean the body and door drain holes.
Lubricate the door hinges and checks,and hood hinges.
Lubricate the door and hood locks and latches.
Lubricate the door rubber weather- strips.
Check the air conditioning system.
Check the power steering fluid level.
Inspect and lubricate automatic transaxle linkage and controls.
Clean the battery and terminals.
Check the brake/clutch fluid level.
