Parking Brake/Low Brake
Fluid Level Warning Light other time, you should slow the vehicle and bring it to a complete stop in a safelocation off the roadway. The brake warning light indicates that the brake fluid level in the brake mas-ter cylinder is low and hydraulic brake fluid conforming to DOT 3 or DOT 4 specifications should be added. Afteradding fluid, if no other trouble is found, the car should be immediately and carefully driven to a Hyundai dealer forinspection. If further trouble is experi- enced, the vehicle should not be driven at all but taken to a dealer by aprofessional towing service or some other safe method. Your Hyundai is equipped with dual-diagonal braking systems. This means you still have braking on two wheels even if one of the dual systems shouldfail. With only one of the dual systems working, more than normal pedal travel and greater pedal pressure are re-quired to stop the car. Also, the car will not stop in as short a distance with only half of the brake system working. If thebrakes fail while you are driving, shift to a lower gear for additional engine braking and stop the car as soon as itis safe to do so.
WARNING:
If you suspect brake trouble, have your brakes checked by a Hyundaidealer as soon as possible. Driving your car with a problem in either the brake electrical system or brakehydraulic system is dangerous, and could result in a serious injury or death.

This is normal and not a cause for concern.Whenever you open the fuel filler
cap, turn it slowly. HFC2016
REMOTE FUEL-FILLER LID RELEASE
B560A02A-AAT The fuel-filler lid may be opened from inside the vehicle by pulling up on the fuel-filler lid opener located on the frontfloor area on the left side of the car.

90AIR CONDITIONER FILTER (IN FRONT OF BLOWER UNIT)
B740D01A-AAT Operation Tips
o If the interior of the car is hot when
you first get in, open the windows for a few minutes to expel the hot air.
o When you are using the air condition-
ing system, keep all windows closedto keep hot air out.
o When moving slowly, as in heavy
traffic, shift to a lower gear. Thisincreases engine speed, which in turn increases the speed of the air conditioning compressor.
o On steep grades, turn the air condi- tioning off to avoid the possibility ofthe engine over-heating.
o During winter months or in periods when the air conditioning is not usedregularly, run the air conditioning onceevery month for a few minutes. This will help circulate the lubricants and keep your system in peak operatingcondition. B760A03FC-GAT (If Installed) The air conditioner filter is located in front of the blower unit behind the glove box. It operates to decrease pollutants from entering the car.To replace the air conditioner filter, refer to the page 6-26.
CAUTION:
o Replace the filter every 20,000 km (12,000 miles) or once a year. If the car is being driven in severe con-ditions such as dusty, rough roads, more frequent air condi- tioner filter inspections andchanges are required.
o When the air flow rate is decreased,
it must be checked at an autho-rized dealer.

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 windows immediately. o Do not inhale exhaust fumes. Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by asphyxiation. o Be sure the exhaust system does not leak. 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 your Hyundai dealer. o Do not run the engine in an enclosed area. Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run theengine in your garage any longer than it takes to start the engine and back the car out. o Avoid idling the engine for prolonged periods with people inside the car. 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 tail gate 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 ofthe windshield are kept clear of snow, ice, leaves or other obstructions.
