DRIVING YOUR HYUNDAI
2- 4 C070A02A-AAT OPERATING THE MANUAL TRANSAXLE
HFC3029
Your Hyundai's manual transaxle has a conven- tional shift pattern. This shift pattern is imprinted on the shift knob. The transaxle is fully synchro- nized in all forward gears so shifting to either a higher or a lower gear is easily accomplished.
C055B01B-GAT STARTING AND STOPPING THE ENGINE FOR TURBO CHARGER INTERCOOLER (DIESEL ENGINE)
(1) Do not race the engine or sudden accelerate
the engine immediately after start it. If the engine is cold, allow the engine to idle for several seconds before it is driven to ensure sufficient lubrication of the turbo charger unit.
(2) After high speed or extended driving, requir- ing a heavy engine load, the engine should be allowed to idle about 1 minute before turning it off.
NOTE: If the engine were not started 10 seconds after the preheating is completed, turn the ignition key once more to the "LOCK" posi- tion, and then to the "ON" position, in order to preheat again. WARNING: Be sure that the clutch is fully depressed when starting a manual transaxle vehicle. Otherwise there is the potential to cause damage to the vehicle or injury to someone inside or outside the vehicle as a result of the forward or backward movement of the vehi- cle that will occur if the clutch is not de- pressed when the vehicle is started.
5. Turn the ignition key to the "Start" position
and release it when the engine starts. This idle time will allow the turbo charger to cool prior to shutting the engine off.
WARNING: Do not turn the engine off immediately after it has been subjected to a heavy load. Doing so may cause severe damage to the engine or turbo charger unit. NOTE:
o To shift into reverse, rest the lever in
neutral for at least 3 seconds after yourcar is completely stopped. Then move the lever into the reverse position.
o During cold weather, shifting may be dif- ficult until the transaxle lubricant has warmed up. This is normal and not harm- ful to the transaxle.
o If you 've come to a complete stop and it's hard to shift into 1 st
or R(Reverse), put the
shift lever in N(Neutral) position and re-lease the clutch. Press the clutch pedal back down, and then shift into 1 st
or
R(Reverse) gear position.
o Do not use the shift lever as a handrest during driving, as this can result in prema-ture wear of the transaxle shift forks.
CAUTION: When downshifting from fifth gear to fourth gear, caution should be taken not to inadvert- ently press the gear shift lever sideways in such a manner that second gear is engaged. Such a drastic downshift may cause the en- gine speed to increase to the point that the tachometer will enter the red zone. Such over-revving of the engine may possibly cause engine damage.

DRIVING YOUR HYUNDAI 2- 7
C090I02A-AAT 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", "2" or "L" 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 when you leave the vehicle, even momentarily. Never leave the vehicle unattended while the engine is running.
o Check the automatic transaxle fluid level regularly, and add fluid as necessary. See the maintenance schedule for the proper fluid recommendation.
C090N02A-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 car from moving.
o Exercise extreme caution when driving on a slippery surface. Be especially careful when braking, accelerating or shifting gears. On a slippery surface, an abrupt change in vehicle speed can cause the drive wheels to lose traction and the vehicle to go out of control.
o Turn the overdrive switch on for good fuel economy and smooth driving. If engine brak- ing is needed in the "D" range or if repeated upshifting and downshifting between 3rd and 4th gear is needed when climbing a gentle slope, it is recommended that the overdrive switch be turned off. Turn the overdrive switch back on immediately afterward.
WARNING:
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 driv- er oversteers to reenter the roadway. C090P01A-GAT Overdrive Switch
HFC3023
When the overdrive switch is turned on, the transaxle will automatically upshift to the second, third and overdrive gears. When the overdrive switch is turned off, the transaxle will not upshift to the overdrive gear. For normal driving, the selector lever should be left in the "D" position and the overdrive switch turned on. If you need to accelerate rapidly, press the accel- erator pedal all the way to the floor. The transaxle will automatically shift to a lower gear, depending on the vehicle speed and load.
o In the event your vehicle leaves the road- way, do not steer sharply. Instead, slow down before pulling back into the travel lanes.
o In a collision crash, an unbelted person is
significantly more likely to die than a per- son wearing a seatbelt.
