cycles. Use this function when the wind-
shield is dirty. The spray and wiper oper-
ation will continue until you release the

WARNING - ENGINE EXHAUST CAN BE DANGEROUS!
Engine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle, open the win-
dows immediately.
• Do not inhale exhaust fumes.
Exhaust fumes contain carbon monoxide, a colourless, odourless gas that can cause unconsciousness and death by asphyx- iation.
The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose. If you hear
a change in the sound of the exhaust or if you drive over something that strikes the underneath side of the car, have the
exhaust system checked as soon as possible by an authorised HYUNDAI dealer.
Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the engine in your
garage any longer than it takes to start the engine and back the car out.
If it is necessary to idle the engine for a prolonged period with people inside the car, be sure to do so only in an open area
with the air intake set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn into the interior.
If you must drive with the trunk open because you are carrying objects that make this necessary:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the windshie ld are
kept clear of snow, ice, leaves or other obstructions.

WARNING - Driving under
the influence of alcohol or drugs
Driving under the influence of
drugs or alcohol is dangerous and
is one of the major contributing fac-
tors to the road deaths each year.Even a small amount of alcohol will
affect your reflexes, perceptions
and judgement. Driving while under
the influence of drugs is as danger-
ous or more dangerous than driv-ing drunk.
You are much more likely to have a
serious accident if you drink or
take drugs and drive.
If you are drinking or taking drugs,
don’t drive. Do not ride with a driv-er who has been drinking or taking
drugs. Choose a designated driveror call a cab.

The highly efficient automatic transaxle
has 4 (or 5) forward gears and one
reverse gear. The individual gears are
selected automatically, depending on the
position of the shift lever.

position, the brake pedal must be
depressed with the ignition switch ON.
✽✽
NOTICE
The first few shifts on a new vehicle, or if the battery has been disconnected,
may be somewhat abrupt. This is a nor-mal condition, and the shifting sequence
will adjust after shifts are cycled a few
times by the TCM (Transaxle Control
Module) or PCM (Powertrain ControlModule).
For smooth operation, depress the brake pedal when shifting from N (Neutral) to a forward or reverse gear.

Transaxle ranges
The indicator lights in the instrument
cluster displays the shift lever position

ple, especially children, beforeputting a car into D (Drive) or R
(Reverse).
Before leaving the driver’s seat, always make sure the shift lever
is in the P (Park) position; then
set the parking brake fully and
shut the engine off. Unexpected
and sudden vehicle movementcan occur if these precautions
are not followed in the order iden-tified.
CAUTION
To avoid damage to your
transaxle, do not accelerate theengine in R (Reverse) or any for- ward gear position with the
brakes on.
When stopped on an upgrade, do not hold the vehicle stationarywith engine power. Use the serv-ice brake or the parking brake.
Do not shift from N (Neutral) or P (Park) into D (Drive), or R(Reverse) when the engine is above idle speed.

the vehicle, do not use the
gearshift lever in place of the
parking brake. Set the parkingbrake 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.
