Shift-Lock System
For your safety, the automatic trans-
mission has a shift-lock system
which prevents shifting the transmis-
sion from P (Park) into R (Reverse)
unless the brake pedal is depressed.
To shift the transmission from P
(Park) into R (Reverse):
1. Depress and hold the brake pedal.
2. Start the engine or place the igni-tion switch in the ON position.
3. Move the shift lever.
Shift-Lock Release
If the shift lever cannot be moved from
the P (Park) position into R (Reverse)
position with the brake pedal
depressed, continue depressing the
brake, and then do the following:
1. Place the ignition switch in the LOCK/OFF position.
2. Apply the parking brake.
3. Carefully remove the cap (1) cov- ering the shift-lock release access
hole.
4. Insert a tool (e.g. flathead screw- driver) into the access hole and
press down on the tool. 5. Move the shift lever.
6. Remove the tool from the shift-
lock override access hole then
install the cap.
If you need to use the shift-lock
release, have your vehicle inspected
by an authorized HYUNDAI dealer
immediately.

Parking
Always come to a complete stop and
continue to depress the brake pedal.
Move the shift lever into the P (Park)
position, apply the parking brake,
and place the ignition switch in the
LOCK/OFF position. Take the Key
with you when exiting the vehicle.
Good Driving Practices
Never move the shift lever from P(Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.
Never move the shift lever into P (Park) when the vehicle is in
motion.
Be sure the vehicle is completely stopped before you attempt to shift
into R (Reverse) or D (Drive).
Do not move the shift lever to N (Neutral) when driving. Doing so
may result in an accident because
of a loss of engine braking and the
transmission could be damaged.
Do not drive with your foot resting on the brake pedal. Even light, but
consistent pedal pressure can
result in the brakes overheating,
brake wear and possibly even
brake failure.
Depressing both accelerator and brake pedals at the same time can
trigger logic for engine power
reduction to assure vehicle decel-
eration. Vehicle acceleration will
resume after the brake pedal is
released. When driving in Manual shift mode,
slow down before shifting to a
lower gear. Otherwise, the lower
gear may not be engaged if the
engine rpms are outside of the
allowable range.
Always apply the parking brake when leaving the vehicle. Do not
depend on placing the transmis-
sion in P (Park) to keep the vehicle
from moving.
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
may cause loss of vehicle control
resulting in an accident.
Optimum vehicle performance and economy is obtained by smoothly
depressing and releasing the
accelerator.
When you stay in the vehicle
with the engine running, be
careful not to depress the accel-
erator pedal for a long period of
time. The engine or exhaust
system may overheat and start
a fire.
The exhaust gas and the
exhaust system are very hot.
Keep away from the exhaust
system components.
Do not stop or park over flam-
mable materials, such as dry
grass, paper or leaves. They
may ignite and cause a fire.

Information - Kickdown
Mechanism
Use the kickdown mechanism for
maximum acceleration. Depress the
accelerator pedal beyond the pressure
point. The automatic transmission will
shift to a lower gear depending on the
engine speed.
Moving up a steep grade from a standing start
To move up a steep grade from a
standing start, depress the brake
pedal, shift the shift lever to D
(Drive). Depress the accelerator
gradually while releasing the service
brakes.

To reduce the risk of SERIOUS
INJURY or DEATH:
ALWAYS wear your seatbelt.
In a collision, an unbelted
occupant is significantly more
likely to be seriously injured
or killed than a properly belt-
ed occupant.
Avoid high speeds when cor-
nering or turning.
Do not make quick steering
wheel movements, such as
sharp lane changes or fast,
sharp turns.
The risk of rollover is greatly
increased if you lose control
of your vehicle at highway
speeds.
Loss of control often occurs if
two or more wheels drop off
the roadway and the driver
over steers to reenter the
roadway.
(Continued)
(Continued)
In the event your vehicle
leaves the roadway, do not
steer sharply. Instead, slow
down before pulling back into
the travel lanes.
HYUNDAI recommends you
follow all posted speed limits.
WARNING
If your vehicle becomes stuck in
snow, mud, sand, etc., then you
may attempt to rock the vehicle
free by moving it forward and
backward. Do not attempt this
procedure if people or objects
are anywhere near the vehicle.
During the rocking operation
the vehicle may suddenly move
forward or backward as it
becomes unstuck, causing
injury or damage to nearby peo-
ple or objects.
WARNING

Driving your vehicle
Power Brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
You can still stop your vehicle by
applying greater force to the brake
pedal than typical. The stopping dis-
tance, however, will be longer than
with power brakes.
When the engine is not running, the
reserve brake power is partially
depleted each time the brake pedal
is applied. Do not pump the brake
pedal when the power assist has
been interrupted.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces.

Take the following precautions:
Do not drive with your foot
resting on the brake pedal.
This will create abnormal high
brake temperatures, exces-
sive brake lining and pad
wear, and increased stopping
distances.
When descending a long or
steep hill, shift to a lower gear
and avoid continuous applica-
tion of the brakes. Applying
the brakes continuously can
cause the brakes to overheat
and could result in a tempo-
rary loss of braking perform-
ance.
(Continued)
(Continued)
Wet brakes may impair the
vehicle's ability to safely slow
down; the vehicle may also
pull to one side when the
brakes are applied. Applying
the brakes lightly will indicate
whether they have been
affected in this way. Always
test your brakes in this fash-
ion after driving through deep
water. To dry the brakes, light-
ly tap the brake pedal to heat
up the brakes while maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at high
speeds until the brakes func-
tion correctly.
