Air conditioning system operation tips
If the vehicle has been parked in directsunlight during hot weather, open the
windows for a short time to let the hot
air inside the vehicle escape.
To help reduce moisture inside of win- dows on rainy or humid days, decrease
the humidity inside the vehicle by oper-
ating the air conditioning system.
During air conditioning system opera- tion, you may occasionally notice a
slight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
Use the air conditioning system every month, even if only for a few minutes,
to ensure maximum system perform-
ance.
When using the air conditioning sys- tem, you may notice clear water drip-
ping (or even puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic.
Operating the air conditioning system in the recirculated air position does
provide maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to
become stale.
Climate control air filter
(if equipped)
The climate control air filter installed
behind the glove box, filters the dust or
other pollutants that come into the vehi-
cle from the outside through the heating
and air conditioning system. If dust or
other pollutants accumulate in the filter
over a period of time, the air flow from the
air vents may decrease, resulting in
moisture accumulation on the inside of
the windshield even when the outside
(fresh) air position is selected. If this hap-
pens, have the climate control air filter
replaced by an authorized Hyundai deal-
er.

Replace the filter every 10,000
miles (15,000 km) or once a year.
If the car is being driven in severeconditions such as dusty, roughroads, more frequent climate con-trol air filter inspections andchanges are required.
When the air flow rate is sudden- ly decreased, the system shouldbe checked at an authorized deal-er.

trical accessories are operative.
✽ ✽NOTICE
If difficulty is experienced turning the
ignition switch to the ACC position, turn
the key while turning the steering wheel
right and left to release the tension.
ON
The warning lights can be checked
before the engine is started. This is the
normal running position after the engine
is started.
Do not leave the ignition switch ON if the
engine is not running to prevent batterydischarge.
START

tion to start the engine. The engine will
crank until you release the key; then it
returns to the ON position. The brake
warning lamp can be checked in this
position.
Starting the gasoline engine
1. Make sure the parking brake is applied.
2. Manual Transaxle - Depress the
clutch pedal fully and shift the
transaxle into Neutral. Keep the clutch
pedal and brake pedal depressed
while turning the ignition switch to the
start position.
Automatic Transaxle - Place the
transaxle shift lever in P (Park).
Depress the brake pedal fully.
You can also start the engine when the shift lever is in the N (Neutral)position.
WARNING - Ignition key
Never turn the ignition switch to
LOCK or ACC while the vehicle is
moving. This would result in loss
of directional control and braking
function, which could cause an
accident.
The anti-theft steering column lock is not a substitute for the parking
brake. Before leaving the driver’s
seat, always make sure the shift
lever is engaged in P (Park) for the
automatic transaxle and set the
parking brake fully and shut the
engine off. Unexpected and sud-
den vehicle movement may occur
if these precautions are not taken.
Never reach for the ignition switch, or any other controls through the
steering wheel while the vehicle is
in motion. The presence of your
hand or arm in this area could
cause a loss of vehicle control, an
accident and serious bodily injury
or death.
Do not place any movable objects around the driver’s seat as they
may move while driving, interfere
with the driver and lead to an acci-
dent.
WARNING
Always wear appropriate shoes
when operating your vehicle.
Unsuitable shoes (high heels, ski
boots,etc.) may interfere with your
ability to use the brake and acceler-
ator pedal, and the clutch (if
equipped).
STARTING THE ENGINE

519
Driving your vehicle
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, there
may be a malfunction in the brake sys-
tem. 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.
Anti-lock brake system (ABS)
(if equipped)

W-75
WARNING
ABS (ESC) will not prevent acci-
dents due to improper or danger-
ous driving maneuvers. Even
though vehicle control is improved
during emergency braking, always
maintain a safe distance between
you and objects ahead. Vehicle
speeds should always be reduced
during extreme road conditions.
The braking distance for cars
equipped with an anti-lock braking
system (Electronic Stability Control
System) may be longer than for
those without it in the following
road conditions.
During these conditions the vehicle
should be driven at reduced
speeds:
Rough, gravel or snow-coveredroads.
With tire chains installed.
On roads where the road surface is pitted or has different surface
height.
(Continued)
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 a person who is unfa- miliar with the vehicle or children
to touch the parking brake. If the
parking brake is released unin-
tentionally, 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.
