OVERDRIVE SWITCH
HFC3023-D
The overdrive switch prevents the transaxle
upshifting higher than third gear when the
switch is turned "OFF". The transaxle will start
from rest in first gear and upshift to second
and third gear depending upon the roadspeed
and throttle opening but will not upshift to
fourth gear. When the overdrive switch is
turned "ON", the transaxle will start from rest
in first gear and will upshift, depending upon
roadspeed and throttle opening to second,
third and fourth gear. Therefore, when the
overdrive switch is turned "OFF", the transaxle
performs as a three speed unit and the over-
drive warning light located in the instrument
cluster will be illuminated. When the overdrive
switch is turned "ON", the transaxle functions
as a fully automatic four speed unit with the
maximum fuel economy potential of the ve-
hicle being realized.
DRIVING YOUR HYUNDAI
SC140A1-E
EFFECTIVE BRAKING
Braking system performance and friction ma-
terial life are greatly affected by the driving
style adopted. The following suggestions are
made to assist in achieving the best results
from the braking system.
o Anticipate the road and conditions ahead
in order that heavy braking may be avoided.
o When descending long gradients, use the
engine to assist in retarding the vehicle to
minimize the possibility of brake fade oc-
curring.
o When trailer towing, ensure that the trailer
brakes function correctly and use engine
braking to assist the vehicle braking system.
o Use only genuine Hyundai replacement
brake pads and shoes to ensure consis-
tent friction characteristics and wear rates.
o After driving through deep water (e.g.
fording), the brakes may become wet and
performance reduced. Always check brake
efficiency after emerging from the water
and dry the brakes by lightly depressing
the brake pedal several times whilst driv-
ing slowly.
o Apply the parking brake only when the
vehicle is at rest.
o Since the power assistance provided by
the brake servo is derived from the engine,
coasting with the engine turned off or tow-
ing of the vehicle with the engine turned off
will result in greatly increased pedal pres-
sures being required to stop the vehicle.
o Do not hold the vehicle on the upgrade
with the accelerator pedal. This can cause
the transmission to overheat. Always use
the brake pedal or parking brake.

ANTI-LOCK BRAKE SYSTEM
(Not all models)
The Anti-Lock Brake System (ABS) is de-
signed to prevent wheel lock-up during sud-
den braking or on hazardous road surfaces.
The ABS control module monitors the wheel
speed and controls the pressure applied to
each brake. Thus, in emergency situations or
on slick roads, ABS will increase vehicle con-
trol during braking.
NOTE:
During ABS operation, a slight pulsation
may be felt in the brake pedal when the
brakes are applied. Also, a noise may be
heard in the engine compartment whilst
braking. These conditions are normal and
indicate that the anti-lock brake system is
functioning properly.
WARNING:
ABS will not prevent accidents due to im-
proper or dangerous driving maneuvers.
Even though vehicle control is improved
during emergency braking, always maintain
a safe distance between you and objects
ahead. Vehicle speeds should always be
reduced during extreme road conditions.
