Hand brake & brake fluidwarning
Hand brake warning This light is illuminated when the hand
brake is applied with the ignition switch in
the START or ON position. The warning
light should go off when the hand brakeis released. Low brake fluid level warning
If the warning light remains on, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains on:
1. Drive carefully to the nearest safe location and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately and add
fluid as required. Then check all brake
components for fluid leaks.
3. Do not drive the vehicle if leaks are found, the warning light remains on or
the brakes do not operate properly.
Have it towed to any authorised
Hyundai dealer for a brake system
inspection and necessary repairs. Your vehicle is equipped with dual-diago-
nal braking systems. This means you still
have braking on two wheels even if one
of the dual systems should fail. With only
one of the dual systems working, more
than normal pedal travel and greaterpedal pressure are required to stop the
car. Also, the car will not stop in as short
a distance with only a portion of the
brake system working. If the brakes fail
while you are driving, shift to a lower gear
for additional engine braking and stop the
car as soon as it is safe to do so.
To check bulb operation, check whether
the hand brake and brake fluid warning
light illuminates when the ignition switchis in the ON position.
CAUTION
If the oil pressure warning light
stays on while the engine is run- ning, serious engine damage mayresult. The oil pressure warning
light comes on whenever there isinsufficient oil pressure. In normaloperation, it should come on whenthe ignition switch is turned on,
then go out when the engine isstarted. If the oil pressure warninglight stays on while the engine is running, there is a serious malfunc-
tion.
If this happens, stop the car assoon as it is safe to do so, turn offthe engine and check the oil level. If
the oil level is low, fill the engine oilto the proper level and start theengine again. If the light stays onwith the engine running, turn the
engine off immediately. In anyinstance where the oil light stays onwhen the engine is running, the engine should be checked by an
authorised Hyundai dealer beforethe car is driven again.
WARNING
Driving the vehicle with a warning
light on is dangerous. If the brake
warning light remains on, have the
brakes checked and repaired imme-
diately by an authorised Hyundai
dealer.

cates that a potential problem has been
detected somewhere in the emissioncontrol system. This light will also illuminate when the
ignition switch is turned to the ON posi-
tion, and will go out in a few seconds
after the engine is started. If it illuminates
while driving, or does not illuminate when
the ignition key is turned to the ON posi-
tion, take your vehicle to your nearest

switch is ON. The warning light illumi-
nates if the temperature of the engine
coolant is above 120°C (248°F) and the
warning light turns off if the temperature
of the engine coolant is below 115°C(239°F).
If the warning light illuminates, pull over
and stop as soon as possible and turn off
the engine. Then open the hood and
check the coolant level (If your vehicle
overheats, refer to “If the engine over-
heats” in the Index.) and the water pump
drive belt. If you suspect cooling system
trouble, have your cooling system
checked by a Hyundai dealer as soon as
possible.

Air conditioning system operation tips
If the vehicle has been parked in direct
sunlight 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 aslight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
Use the air conditioning system every month 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 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 authorised Hyundai deal-
er.

CAUTION
Replace the filter every 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 and changes are required.
When the air flow rate is sudden- ly decreased, the system shouldbe checked at an authorised deal-
er.

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 boot lid 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.

Driving your vehicle
Before entering vehicle
• Be sure that all windows, outside mir-ror(s), and outside lights are clean.
Check the condition of the tyres.
Check under the vehicle for any sign of leaks.
Be sure there are no obstacles behind you if you intend to back up.
Necessary inspections
Fluid levels, such as engine oil, engine
coolant, brake fluid, and washer fluid
should be checked on a regular basis,
with the exact interval depending on the
fluid. Further details are provided in
Section 7, “Maintenance”.
Before starting
Close and lock all doors.
Position the seat so that all controls are easily reached.
Adjust the inside and outside rearview mirrors. Be sure that all lights work.
Check all gauges.

BEFORE DRIVING
WARNING
All passengers must be properly
belted whenever the vehicle is mov-
ing. Refer to “Seat belts” in section
3 for more information on their
proper use.
WARNING
Always check the surrounding
areas near your vehicle for people,
especially children, before putting a
car into “Drive” or “Reverse”.
WARNING - Driving under
the influence of alcohol or drugs
Drinking and driving is dangerous.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgement.Driving while under the influence of
drugs is as dangerous or more dan-
gerous than driving 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.
WARNING
When you intend to park or stop the
vehicle with the engine on, be care-ful not to depress the accelerator
pedal for a long period of time. It
may overheat the engine or exhaust
system and cause fire.
