INSTRUMENTS AND CONTROLS
45REAR HEATER AND AIR CONDITIONER
C710A01P-GAT (If installed) The rear heater can be operated with the ignition switch at the "ON" positionby depressing the main switch in the instrument panel.
C700A01P-GAT Operation Tips
o If the interior of the vehicle is hot
when you first get in, open the win- dows for a few minutes to expel the hot air.
o When you are using the air condi- tioning system, keep all windowsclosed to keep hot air out.
o When you must drive slowly, as in heavy traffic, shift to a lower gear.This increases engine speed, which in turn increases the speed of theair conditioning compressor.
o When driving up long grades, turn
occasionally the air conditioner offto avoid the possibility of the engine overheating.
o During winter months or in periods when the air conditioner is not usedregularly, turn on the air conditioner switch occasionally for a few min-utes. This will help circulate the lubricants and keep your system in peak operating condition.
For dehumidified heating:
o Turn on the fan control switch.
o Turn on the air conditioner switch by
pushing in on the switch. The air conditioner indicator light should come on at the same time.
o Set the air intake control to the "Fresh".
o Set the air flow control to the "Face".
o Adjust the fan control to the desired
speed. For more rapid action, set the fan at one of the higher speeds.
o Adjust the temperature control to provide the desired amount ofwarmth.

D110A01P-GAT Good Braking Practices
WARNING:
Nothing should be carried on top of the cargo area cover behind the rear seat. If there were an accident or a sudden stop, such objectscould move forward and cause dam- age to the vehicle or injure the oc- cupants.
o After being parked, check to be sure the parking brake is not engagedand that the parking brake indicator light is out before driving away.
o Driving through water may get the brakes wet. They can also get wetwhen the vehicle is washed. Your vehicle may not stop as quickly if thebrakes are wet and it may also pull to one side. To dry the brakes, apply the brakes lightly until the brakingaction returns to normal, taking care to keep the vehicle under control at all times. If the braking action doesnot return to normal, stop as soon as it is safe to do so and call your Hyundai dealer for assistance. o Don’t coast down hills with the ve-
hicle out of gear. This may be ex-tremely hazardous. Keep the vehicle in gear at all times, use the brakes to slow down, thenshift to a lower gear so that engine braking will help you maintain a safe speed.
o Don’t "ride" the brake pedal. Rest- ing your foot on the brake pedalwhile driving can be dangerous be-cause it can result in the brakes overheating and losing their effec- tiveness. It also increases the wearof the brake components.
o If a tire goes flat while you are
driving, apply the brakes gently andkeep the vehicle pointed straight ahead while you slow down. When you are moving slowly enough for itto be safe to do so, pull off the road and stop in a safe place.
o If your vehicle is equipped with an automatic transmission, don’t letyour vehicle creep forward. To avoid creeping forward, keepyour foot on the brake pedal when the vehicle is stopped.
D130A01P-GAT Loading Loading should not be to the point at which the Maximum Gross VehicleWeight is exceeded. Loading should be as uniform as pos- sible.Driving stability will be reduced if the load is unequal between front/rear or left/right.Avoid sudden starts, sudden braking, and sharp cornering.

44IN CASE OF EMERGENCY
18BLEEDING THE FUEL SYSTEM
CAUTION:
If overheating should occur when towing, (temperature gauge reads near red zone), taking the followingaction may reduce or eliminate the problem.
1. Turn off the air conditioner.
2. Reduce highway speed.
3. Select a lower gear when going uphill.
4. While in stop and go traffic, place
the gear selection in park or neu-tral and idle the engine at a higher speed.
! E090A01P-GAT The fuel system should be bled to remove air as described in the illustra-tion if the fuel supply is exhausted during travel, when the fuel filter is replaced, or if the vehicle is not usedfor a long time.
1. Loosen the air plug at the top of the
fuel filter. E090A01P
13.Avoid holding the brake pedal down
too long or too frequently. This could cause the brakes to overheat, re- sulting in reduced braking efficiency.
14.When going down a hill, shift into a
lower gear and use the engine brak-ing effect. When ascending a long grade, downshift the transmissionto a lower gear and reduce speed to reduce chances of engine over- loading and/or overheating.
15.If you have to stop while going uphill, do not hold the vehicle inplace by pressing on the accelera-tor. This can cause the automatic transmission to overheat. Use the parking brake or footbrake.
NOTE: When towing, check transmission fluid more frequently.

44IN CASE OF EMERGENCY
22IF THE ENGINE OVERHEATS
CAUTION:
o Do not allow the jumper cable clips to touch one another.
o Do not connect the jumper cable
to the negative terminal of the flat battery. The battery generates explosive gas, and a spark caused whenthe jumper cable is disconnected from the negative terminal could ignite this gas and cause an ex-plosion.
o Be careful that the jumper cable
becomes not caught in the cool-ing fan, etc.
! D030A02A-AAT If your temperature gauge indicates overheating, you experience a loss of power, or hear loud pinging or knock- ing and the engine is probably too hot.If this happens to you, you should:
1. Pull off the road and stop as soon as
it is safe to do so.
2. Place the gear selector lever in "P"
(automatic transmission), or neutral (manual transmission) and set the parking brake. If the air conditioning is on, turn it off.
3. If engine coolant is running out un- der the car or steam is coming outfrom the hood, stop the engine. Donot open the hood until the engine coolant has stopped running or the steaming has stopped. If there is novisible loss of engine coolant and no steam, leave the engine running and check to be sure the enginecooling fan is operating. If the fan is not running, turn the engine off.
the other end to the engine block of the vehicle with the flat batteryat the point farthest from the battery.
8. Start engine as described "Starting the engine" in section 3.
9. After the engine is started, discon- nect the cables in the reverse order.
1. Both batteries must be 12V. The
capacity (Ah) of the battery supply- ing current should not be signifi- cantly below that of the discharged battery.
2. Use only heavy-duty jumper cables.
3. A discharged battery can freeze. A
frozen battery must be thawed out before connecting the jumper cables.
4. There should be no contact be-
tween the two vehicles; otherwisecurrent may flow when the positive terminal is connected.
5. The discharged battery must be correctly connected to the vehicleelectrical system.
6. Run the engine of the vehicle sup- plying current.
7. Connect the jumper cables as fol-
lows:
(1) Connect one end of one jumper cable to the positive terminal of the flat battery, and the other end to the positive terminal of the booster battery.
(2) Connect one end of the other jumper cable to the negative ter-minal of the booster battery, and

4. Check to see if the water pump drive belt is missing. If it is not missing, check to see that it is tight. If the drive belt seems to be satisfactory, check for engine coolant leakingfrom the radiator, hoses or under the car. (If the air conditioning had been in use, it is normal for coldwater to be draining from it when you stop).
!WARNING:
While the engine is running, keep hair, hands, long hair and clothing away from moving parts such as the fan and drive belts to preventinjury.
!WARNING (Diesel only):
Never work on injection system with engine running or within 30 sec- onds after shutting off engine. High pressure pump, rail, injectors andhigh pressure pipes are subject to high pressure even after the engine stopped. The fuel jet produced byfuel leaks may cause serious in- jury, if it touch the body. People using pacemakers should not movethan 30cm closer to the ECU or wiring harness within the engine room while engine is running, sincethe high currents in the Common Rail system produce considerable magnetic fields.
5. If the water pump drive belt is bro- ken or engine coolant is leaking out, stop the engine immediately and call the nearest Hyundai dealer for assistance.!WARNING:
Do not remove the radiator cap when the engine is hot. This can allow coolant to be blown out of the open- ing and cause serious burns.
6. If you cannot find the cause of the overheating, wait until the engine temperature has returned to nor-mal. Then, if the engine coolant has been lost, carefully add coolant to the reservoir (page 8-12) to bringthe fluid level in the reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. Ifoverheating happens again, call a Hyundai dealer for assistance.
CAUTION:
Serious loss of engine coolant indi-cates there is a leak in the coolingsystem and this should be checked as soon as possible by a Hyundai dealer.
