Parking Brake/Low Brake Fluid Level Warning Light WARNING:
In the event of problems being sus- pected with the braking system, the advice of the nearest Hyundai authorised repairer must be soughtbefore the vehicle is driven. Driving the vehicle with either an electrical or hydraulic braking system defectmay be dangerous, resulting in acci- dent or personal injury. Warning light operation The parking brake/low brake fluid level warning light will be illuminated when-ever the ignition switch is turned to the "ON" position irrespective of whether or not the parking brake is applied andmust be extinguished when the engine starts and the parking brake released. If the warning light fails to extinguish orilluminates at any other time, the ve- hicle must be brought to rest in a safe location and the level of brake fluid inthe reservoir checked. If the fluid level is incorrect, fluid con- forming to DOT 3 or DOT 4 specifica-tions should be added. If, after correct- ing the brake fluid level, the warning light continues to be illuminated, theadvice of the nearest Hyundai authorised repairer must be sought before the ve- hicle is driven again.The Hyundai Matrix is equipped with a diagonally split dual braking system which will ensure that in the event ofone of the brake circuits becoming defective, approximately fifty per cent of the normal braking performance willbe available.

Overdrive Off Indicator
Light (Not all models)
When the overdrive (4th gear) switch is turned off and the operation of overdrive(4th gear) is cancelled, the overdrive warning light (O/D OFF) will be illumi- nated. When the switch is at the onposition, the gearbox will operate in the normal fully automatic mode and the warning light will be extinguished. If failure of one of the circuits occurs,the required amount of pedal effort,pedal travel and stopping distance will be increased. Use of the gearbox is recommended to assist in bringing thevehicle to rest. The vehicle must not be driven once brake failure has occurred until the system has been repaired andis functioning normally. The braking system employs a vacuum servo in order that the pedal efforts arereduced. Power for the servo is derived from the engine and therefore, in the event of the engine stopping or thevehicle being towed, pedal efforts will be substantially increased.

o Automotive fuels are flammable/
explosive materials. When refuel- ing, please note the following guidelines carefully.
o Before touching the fuel nozzle or fuel filler cap, have one's hands incontact with metal parts away from the filler neck to discharge staticelectricity.
o Do not get back in the vehicle
whilst refueling. Do not operateanything that can produce static electricity. Static electricity dis- charge can ignite fuel vapors re-sulting in explosion.
o When using a portable fuel con-
tainer be sure to place the con-tainer on the ground whilst refuel- ing. Static electricity discharge from the container can ignite fuelvapors causing a fire. Whilst start- ing refueling contact should be maintained until the filling is com-plete. o Do not use cellular phones around
a gas station. The electric currentor electronic interference from cellular phones can ignite fuel vapors causing a fire.
o When refueling always shut the engine off. Sparks by electricalequipment of the engine can ig-nite fuel vapors causing a fire. After refueling, check to make sure the fuel filler cap is securely closed,and then start the engine.
o Do not smoke or try to light ciga-
rettes around a gas station. Auto-motive fuels are flammable.

B750A02A-AAT How Car Audio Works AM and FM radio signals are broadcast from transmitter towers located around your city. They are intercepted by theradio antenna on your car. This signal is then received by the radio and sent to your car speakers.When a strong radio signal has reached your vehicle, the precise engineering of your audio system ensures high qualityreproduction. However, in some cases the signal coming to your vehicle is not strong and clear. This can be dueto factors such as the distance from the radio station, closeness of other strong radio stations or the presence of build-ings, bridges and other large obstruc- tions in the area.STEREO SOUND SYSTEM

C055B01B-GAT STARTING AND STOPPING THE ENGINE FOR TURBOCHARGER INTERCOOLER(DIESEL ENGINE)
(1) Do not race the engine or suddenly
accelerate the engine immediately after starting it. If the engine is cold,allow the engine to idle for several seconds before it is driven to ensure sufficient lubrication of the turbocharger unit.
(2) After high speed or extended driv-
ing, requiring a heavy engine load,the engine should be allowed to idle about 1 minute before turning it off. This idle time will allow the turbocharger to cool prior to shutting the engine off.
WARNING:
Do not turn the engine off immedi- ately after it has been subjected to a heavy load. Doing so may cause severe damage to the engine or turbocharger unit. SC060B1-E FUEL ECONOMY The following suggestions are made to assist in achieving the greatest degreeof fuel economy.
o Maintaining a constant check on fuel
consumption will enable the most economical use pattern and driving style to be adopted.
o Avoid using the vehicle for very short journeys if possible, particularly whena cold start is involved.
o Ensure that tyre pressures are main- tained at the correct level.
o Use only the recommended grade of fuel.
o Avoid carrying unnecessary weight,
and if a roof rack is in use, remove itas soon as possible after use.
o Anticipate the road and conditions
ahead to enable adjustments in speedto be made smoothly. Avoid heavy acceleration and sharp braking.
o Avoid cruising at unnecessary high speeds. o Always ensure that the periodic main-
tenance services are performed by a Hyundai authorised repairer at the time and/or mileage intervals speci- fied.
o Use the air conditioning only when necessary.
