Releasing the parking brake
To release the parking brake, first apply
the foot brake and pull up the parking
brake lever slightly. Secondly depress the
release button (1) and lower the parking
brake lever (2) while holding the button. Check the brake warning light by turning
the ignition switch ON (do not start the
engine). This light will be illuminated
when the parking brake is applied with
the ignition switch in the START or ON
position.
Before driving, be sure the parking brake
is fully released and the brake warning
light is off.
If the brake warning light remains on
after the parking brake is released while
engine is running, there may be a mal-
function in the brake system. Immediate
attention is necessary.
If at all possible, cease driving the vehi-
cle immediately. If that is not possible,
use extreme caution while operating the
vehicle and only continue to drive the
vehicle until you can reach a safe loca-
tion or repair shop.
WARNING
To prevent unintentional move-
ment when stopped and leaving
the vehicle, do not use the
gearshift lever in place of the
parking brake. Set the parking
brake AND make sure the
gearshift lever is securely posi-
tioned in 1st (First) gear or R
(Reverse) for manual transaxle
equipped vehicles and in P (Park)
for automatic transaxle equipped
vehicles.
Never allow anyone who is unfa- miliar with the vehicle to touch
the parking brake. If the parking
brake is released unintentionally,
serious injury may occur.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the car which
can injure occupants or pedestri-
ans.

Good braking practices
After parking the vehicle, check to be
sure the parking brake is not engaged
and that the parking brake indicator
light is out before driving away.
Driving through water may get the brakes wet. They can also get wet
when the car is washed. Wet brakes
can be dangerous! Your car will not
stop as quickly if the brakes are wet.
Wet brakes may cause the car to pull
to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns to
normal, taking care to keep the car
under control at all times. If the braking
action does not return to normal, stop
as soon as it is safe to do so and call
an authorized KIA dealer for assis-
tance. Don't coast down hills with the car out
of gear. This is extremely hazardous.
Keep the car in gear at all times, use
the brakes to slow down, then shift to a
lower gear so that engine braking will
help you maintain a safe speed.
Don't "ride" the brake pedal. Resting your foot on the brake pedal while driv-
ing can be dangerous because it can
result in the brakes overheating and
losing their effectiveness. It also
increases the wear of the brake com-
ponents.
If a tire goes flat while you are driving, apply the brakes gently and keep the
car pointed straight ahead while you
slow down. When you are moving
slowly enough for it to be safe to do so,
pull off the road and stop in a safe
place.
WARNING
Whenever leaving vehicle orparking, always set the parking
brake as far as possible and fully
engage the vehicle's transaxle
into the park position. Vehicles
not fully engaged in park with the
parking brake set are at risk for
moving inadvertently and injur-
ing yourself or others.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the car which
can injure occupants or pedestri-
ans.

Your vehicle's fuel economy depends
mainly on your style of driving, where you
drive and when you drive.
Each of these factors affects how many
kilometers (miles) you can get from a
liter (gallon) of fuel. To operate your vehi-
cle as economically as possible, use the
following driving suggestions to help
save money in both fuel and repairs:
Drive smoothly. Accelerate at a moder-
ate rate. Don't make "jack-rabbit" starts
or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to that of the other traffic so you
don't have to change speeds unneces-
sarily. Avoid heavy traffic whenever
possible. Always maintain a safe dis-
tance from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your car uses.
Driving at a moderate speed, especial-
ly on the highway, is one of the most
effective ways to reduce fuel consump-
tion. Don't "ride" the brake or clutch pedal.
This can increase fuel consumption
and also increase wear on these com-
ponents. In addition, driving with your
foot resting on the brake pedal may
cause the brakes to overheat, which
reduces their effectiveness and may
lead to more serious consequences.
Take care of your tires. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tire
wear. Check the tire pressures at least
once a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting curbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tire wear and may
also result in other problems as well as
greater fuel consumption.
Keep your car in good condition. For better fuel economy and reduced
maintenance costs, maintain your car
in accordance with the maintenance
schedule in Section 7. If you drive your
car in severe conditions, more frequent
maintenance is required (see Section
7 for details). Keep your car clean. For maximum
service, your vehicle should be kept
clean and free of corrosive materials. It
is especially important that mud, dirt,
ice, etc. not be allowed to accumulate
on the underside of the car. This extra
weight can result in increased fuel con-
sumption and also contribute to corro-
sion.
Travel lightly. Don't carry unnecessary weight in your car. Weight reduces fuel
economy.
Don't let the engine idle longer than necessary. If you are waiting (and not
in traffic), turn off your engine and
restart only when you're ready to go.
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 too
high a gear resulting in the 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
speeds.
