B260H01GK-AAT Parking Brake/Low Brake Fluid Level Warning Light
CAUTION: If you suspect brake trouble, have your brakeschecked by a Hyundai dealer as soon aspossible. Driving your car with a problem ineither the brake electrical system or brakehydraulic system is dangerous, and couldresult in a serious injury or death. Warning Light Operation The parking brake/brake fluid level warning light should come on when the parking brake is ap-plied and the ignition switch is turned to "ON" or"START". After the engine is started, the lightshould go out in three seconds.If the parking brake is not applied, the warninglight should come on when the ignition switch isturned to "ON" or "START", then go out in threeseconds. If the light comes on at any other time,you should slow the vehicle and bring it to acomplete stop in a safe location off the roadway.The brake fluid level warning light indicates thatthe brake fluid level in the brake master cylinderis low and hydraulic brake fluid conforming toDOT 3 or DOT 4 specifications should be added.After adding fluid, if no other trouble is found, thecar should be immediately and carefully driven toa Hyundai dealer for inspection. If further troubleis experienced, the vehicle should not be drivenat all but taken to a dealer by a professionaltowing service or some other safe method. Your Hyundai is equipped with dual-diagonalbraking systems. This means you still have brak-ing on two wheels even if one of the dual systemsshould fail. With only one of the dual systemsworking, more than normal pedal travel andgreater pedal pressure are required to stop thecar. Also, the car will not stop in as short adistance with only half of the brake system work-ing. If the brakes fail while you are driving, shift toa lower gear for additional engine braking andstop the car as soon as it is safe to do so.

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 conditioning sys- tem, keep all windows closed to keep hot airout.
o When moving slowly, as in heavy traffic, shift to a lower gear. This increases engine speed,which in turn increases the speed of the airconditioning compressor.
o On steep grades, turn the air conditioner off to avoid the possibility of the engine over-heating.
o During winter months or in periods when the air conditioner is not used regularly, run theair conditioner once every month for a fewminutes. This will help circulate the lubricantsand keep your system in peak operatingcondition.

2- 8 C130A01A-AAT GOOD BRAKING PRACTICES WARNING: Nothing should be carried on top of the shelfpanel behind the rear seat. If there were anaccident or a sudden stop, such objects couldmove forward and cause damage to the ve-hicle or injure the occupants.
o After being parked, check to be sure the
parking brake is not engaged and that the parking brake indicator light is out beforedriving away.
o Driving through water may get the brakes wet. They can also get wet when the car iswashed. Wet brakes can be dangerous! Yourcar will not stop as quickly if the brakes arewet. Wet brakes cause the car to pull to one
side. To dry the brakes, apply the brakeslightly until the braking action returns to nor-mal, taking care to keep the car under controlat all times. If the braking action does notreturn to normal, stop as soon as it is safe todo so and call your Hyundai dealer for assis-tance.
o Don't coast down hills with the car out of gear. This is extremely hazardous. Keep the car ingear at all times, use the brakes to slow down,then shift to a lower gear so that enginebraking will help you maintain a safe speed.
o Don't "ride" the brake pedal. Resting your foot on the brake pedal while driving can be dan-gerous because it can result in the brakes
overheating and losing their effectiveness. It
C090I01L-GAT CAUTION:
o Shift into "R" and "P" position only when
the vehicle has completely stopped.
o Do not accelerate the engine in reverse or any of the forward positions with the brakes applied.
o Always apply the footbrake when shifting from "P" or "N", to "R", "D"position.
o Do not use the "P" (Park) position in place of the parking brake. Always set the park-ing brake, shift the transaxle into "P" (Park)position and turn off the ignition whenyou leave the vehicle, even momentarily.Never leave the vehicle unattended whilethe engine is running.
o Check the automatic transaxle fluid level regularly, and add fluid as necessary.
C090N02O-AAT Good Driving Practices
o Never move the gear selector lever from "P" or "N" to any other position with the acceler- ator pedal depressed.
o Never move the gear selector lever into "P" when the vehicle is in motion.
o Be sure the car is completely stopped before you attempt to shift into "R".
o Never take the car out of gear and coast down a hill. This may be extremely hazardous.Always leave the car in gear when moving.
o Do not "ride" the brakes. This can cause them to overheat and malfunction. Instead, whenyou are driving down a long hill, slow down and shift to a lower gear. When you do this,engine braking will help slow the car.
o Slow down before shifting to a lower gear. Otherwise, the lower gear may not be en-gaged.
o Always use the parking brake. Do not depend on placing the transaxle in "P" to keep the carfrom moving.
o Exercise extreme caution when driving on a slippery surface. Be especially careful whenbraking, accelerating or shifting gears. On aslippery surface, an abrupt change in vehiclespeed can cause the drive wheels to losetraction and the vehicle to go out of control.
WARNING:
o Avoid high cornering speeds.
o Do not make quick steering wheel move- ments, such as sharp lane changes orfast, sharp turns.
o Always wear your seat belts. In a collision crash, un unbelted person issignificantly more likely to die than a per-son wearing a seatbelt.
o The risk of rollover is greatly increased if you lose control of your vehicle at high-way speeds.
o Loss of control often occurs if two or more wheels drop off the roadway and the driveroversteers to reenter the roadway.
o In the event your vehicle leaves the road- way, do not steer sharply. Instead, slowdown before pulling back into the travellanes.
o Never exceed posted speed limits.

ating properly, you can feel a slight pulsa- tion in the vehicle. This is only the effect ofbrake control and indicates nothing un-usual.
3) When the engine starts, a click is heard from the engine compartment; however,this is only the sound of traction controlbeing checked.
4) When moving out of the mud or fresh snow, pressing the accelerator pedal maynot cause the engine speed to increasedue to TCS operation.
C310D01O-AAT Indicators and Warning The indicators should illuminate when the igni- tion key is turned to ON or START but should goout after three seconds.If the indicators do not illuminate, or the TCS orTCS-OFF indicator does not go out after 3 sec-onds, have it checked by an authorized dealer. Should there be any unusual conditions in the device while driving, TCS-OFF indicator illumi-nates as a warning.If TCS-OFF indicator illuminates, pull your car toa safe place and stop the engine.Then, start the engine again to check if the TCS-OFF indicator goes out.
C300A03Y-GAT TRACTION CONTROL SYSTEM (TCS) (If installed)
HGK156A
CAUTION: When the TCS indicator blinks, SLIP controlhas been activated. It also means that theroad is slippery or your car is acceleratingexcessively. In this situation, gently releasefoot pressure from the accelerator pedal andmaintain moderate speed. WARNING: Traction control is only a driving aid; allnormal precautions for driving in inclementweather and on slippery road surfaces shouldbe observed.
On slippery road surfaces, the traction controlsystem (TCS) limits the drive wheels from spin-ning excessively, thus helping the car to acceler-ate. It also provides sufficient driving force andsteering performance as the car turns at acceler-ated speeds. SLIP Control Limits the drive wheels from spinning exces- sively during starting or while making accelerat-ed turns on slippery roads to avoid losing thedriving force of the front wheels. Driving hints TCS does not actively apply brakes. Be sure to decelerate the car sufficiently before enteringcurves. C310B01O-AAT TCS ON/OFF Mode When the TCS is running, the TCS indicator light in the instrument cluster will blink.If you turn the system off by pressing the TCSswitch, the TCS-OFF indicator light will come onand stay on. In the TCS-OFF mode, the SLIPcontrol will be deactivated. Adjust you drivingaccordingly. To turn the system back on, pressthe switch again. The TCS-OFF indicator lightshould go off. NOTE:
1) The TCS mode will automatically be turned
ON after the engine is turned off and re-started.

off your engine and restart only when you're ready to go.
o Remember, your Hyundai does not require extended warm-up. As soon as the engine isrunning smoothly, you can drive away. Invery cold weather, however, give your enginea slightly longer warm-up period.
o Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in too high a gear result-ing in the engine bucking. If this happens, shiftto a lower gear. Over-revving is racing theengine beyond its safe limit. This can beavoided by shifting at the recommendedspeeds.
o Use your air conditioning sparingly. The air conditioning system is operated by enginepower so your fuel economy is reduced whenyou use it.
crease wear on these components. In addi-tion, driving with your foot resting on the brakepedal may cause the brakes to overheat,which reduces their effectiveness and maylead to more serious consequences.
o Take care of your tires. Keep them inflated to the recommended pressure. Incorrect infla-tion, either too much or too little, results inunnecessary tire wear. Check the tire pres-sures at least once a month.
o Be sure that the wheels are aligned correctly. Improper alignment can result from hittingcurbs or driving too fast over irregular surfac-es. Poor alignment causes faster tire wearand may also result in other problems as wellas greater fuel consumption.
o Keep your car in good condition. For better fuel economy and reduced maintenancecosts, maintain your car in accordance withthe maintenance schedule in Section 5. If youdrive your car in severe conditions, morefrequent maintenance is required (see Sec-tion 5 for details).
o Keep your car clean. For maximum service, your Hyundai should be kept clean and free ofcorrosive materials. It is especially importantthat mud, dirt, ice, etc. not be allowed toaccumulate on the underside of the car. Thisextra weight can result in increased fuel con-sumption and also contribute to corrosion.
o Travel lightly. Don't carry unnecessary weight in your car. Weight reduces fuel economy.
o Don't let the engine idle longer than neces- sary. If you are waiting (and not in traffic), turn C150A01A-AAT
SMOOTH CORNERING
Avoid braking or gear changing in corners, espe-cially when roads are wet. Ideally, corners shouldalways be taken under gentle acceleration. If youfollow these suggestions, tire wear will be held toa minimum. C160A01A-AAT WINTER DRIVING The more severe weather conditions of winter result in greater wear and other problems. Tominimize the problems of winter driving, youshould follow these suggestions:
If the indicator remains lit even after the enginehas been started, have your car checked by anauthorized Hyundai dealer. NOTE:
1) When the TCS-OFF indicator illuminates,
traction control is automatically deacti-vated for safety.
2) This warning function is not provided when the driver selects the TCS-OFF mode.
C140A01A-GAT DRIVING FOR ECONOMY You can save fuel and get more kilometers from your car if you follow these suggestions:
o Drive smoothly. Accelerate at a moderate rate. Don't make "jack-rabbit" starts or full- throttle shifts and maintain a steady cruisingspeed. Don't race between stoplights. Try toadjust your speed to that of the other traffic soyou don't have to change speeds unneces-sarily. Avoid heavy traffic whenever possible.Always maintain a safe distance from othervehicles so you can avoid unnecessary brak-ing. This also reduces brake wear.
o Drive at a moderate speed. The faster you drive, the more fuel your car uses. Driving ata moderate speed, especially on the high-way, is one of the most effective ways toreduce fuel consumption.
o Don't "ride" the brake or clutch pedal. This can increase fuel consumption and also in-
