Introduction
No special break-in period is needed. By
following a few simple precautions for the
first 600 miles (1,000 km) you may add to
the performance, economy and life of
your vehicle.
 Do not race the engine.
 While driving, keep your engine speed(rpm, or revolutions per minute)
between 2,000 rpm and 4,000 rpm.
 Do not maintain a single speed for long periods of time, either fast or slow.
Varying engine speed is needed to
properly break-in the engine.
 Avoid hard stops, except in emergen- cies, to allow the brakes to seat prop-
erly.
 Don't let the engine idle longer than 3 minutes at one time.
 Don't tow a trailer during the first 1,200 miles (2,000 km) of operation.VEHICLE BREAK-IN PROCESS

Parking brake & brake fluid
warning lightParking brake warning
This light is illuminated when the parking
brake is applied with the ignition switch in
the START or ON position. The warning
light should go off when the parking
brake is released.
Low brake fluid level warning
If the warning light remains on, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains on:
1. Drive carefully to the nearest safe location and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately and add
fluid as required. Then check all brake
components for fluid leaks.
3. Do not drive the vehicle if leaks are found, the warning light remains on or
the brakes do not operate properly.
Have the vehicle towed to any author-
ized HYUNDAI dealer for a brake sys-
tem inspection and necessary repairs. Your vehicle is equipped with a dual-
diagonal braking system. This means you
still have braking on two wheels even if
one of the brake circuits is damaged or
malfunctions. With only one of the circuits
working, more than normal pedal travel
and greater pedal pressure are required
to stop the car. Also, the car will not stop
in as short a distance with only a portion
of the brake system working. If the
brakes fail while you are driving, shift to a
lower gear for additional engine braking
and stop the car as soon as it is safe to
do so.
To check bulb operation, check whether
the parking brake and brake fluid warning
light illuminates when the ignition switch
is in the ON position.
WARNING
Driving the vehicle with a warning
light on is dangerous. If the brake
warning light remains on, have the
brakes checked and repaired imme-
diately by an authorized HYUNDAI
dealer.
CAUTION
If the oil pressure warning light
stays on while the engine is run- ning, serious engine damage mayresult. The oil pressure warninglight comes on whenever there is insufficient oil pressure. In normaloperation, it should come on whenthe ignition switch is turned on,then go out when the engine is started. If the oil pressure warninglight stays on while the engine isrunning, there is a serious malfunc-tion.
If this happens, stop the car assoon as it is safe to do so, turn offthe engine and check the oil level. Ifthe oil level is low, fill the engine oil to the proper level and start theengine again. If the light stays onwith the engine running, turn theengine off immediately. In any instance where the oil light stays onwhen the engine is running, theengine should be checked by an authorized HYUNDAI dealer beforethe car is driven again.

Features of your vehicle
Low brake vacuum pressure warning
(2.0 TGDI engine only, if equipped)
If the warning light remains on, it may
indicate that the brake vacuum pump has
any problem. Therefore you should avoid
high speed driving or sudden stop, and
you should depress the brake pedal
deeper and harder than usual in braking.
Make sure to have the brake system
checked and repaired by an authorized
HYUNDAI dealer.
Low tire pressure telltale The low tire pressure telltale illuminates
when one or more of your tires is signifi-
cantly underinflated.
The low tire pressure telltale will illumi-
nate after it blinks for approximately one
minute when there is a problem with the
Tire Pressure Monitoring System.
If this occurs, have the system checked
by an authorized HYUNDAI dealer as
soon as possible.
For details, refer to the TPMS on chapter
6.
WARNING
- Low tire pres- sure
Significantly low tire pressure
makes the vehicle unstable and can
contribute to loss of vehicle control
and increased braking distances.
Continued driving on tires with low
pressure will cause the tires to
overheat and fail.
WARNING
- Safe stopping
 The TPMS cannot alert you to
severe and sudden tire damage
caused by external factors.
 If you feel any vehicle instability, immediately take your foot off the
accelerator, apply the brakes
gradually and with light force,
and slowly move to a safe posi-
tion off the road.
WARNING
 Continuous braking while drivingon steep or long downhill may
cause to descend the vacuum
level in brake booster for a time
and turn on the warning light. In
this case, shift down the trans-
mission. If the warning light illu-
minate continuously, stop the
vehicle in the safe location and
wait until the warning light goes
off.
 Driving the vehicle with a warn- ing light on is dangerous. If the
brake warning light remains on,
have the brakes checked and
repaired immediately by an
authorized HYUNDAI dealer.

Driving your vehicle
Good driving practices Never take the vehicle out of gear andcoast down a hill. This is extremely
hazardous. Always leave the vehicle in
gear.
 Do not "ride" the brakes. This can cause them to overheat and malfunc-
tion. Instead, when you are driving
down a long hill, shift to a lower gear.
When you do this, engine braking will
help slow down the vehicle.
 Slow down before shifting to a lower gear. This will help avoid over-revving
the engine, which can cause damage.
 Slow down when you encounter cross winds. This gives you much better con-
trol of your vehicle.
 Be sure the vehicle is completely stopped before you attempt to shift into
R (Reverse). The transaxle can be
damaged if you do not. To shift into R
(Reverse), depress the clutch, move
the shift lever to neutral, wait three sec-
onds, then shift to the R (Reverse)
position.
 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.
WARNING
 Always buckle-up! In a collision,
an unbelted occupant is signifi-
cantly more likely to be seriously
injured or killed than a properly
belted occupant.
 Avoid high speeds when corner- ing 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.
 In the event your vehicle leaves the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
 Never exceed posted speed lim- its.

Driving your vehicle
For smooth operation, depress the brakepedal when shifting from N (Neutral) to aforward or reverse gear. Transaxle ranges
The indicator in the instrument cluster
displays the shift lever position when the
ignition switch is in the ON position.
P (Park)
Always come to a complete stop before
shifting into P (Park). This position locks
the transaxle and prevents the drive
wheels from rotating.
WARNING
- Automatic
transaxle
 Always check the surrounding
areas near your vehicle for peo-
ple, especially children, before
shifting a car into D (Drive) or R
(Reverse).
 Before leaving the driver’s seat, always make sure the shift lever
is in the P (Park) position; then
set the parking brake fully and
shut the engine off. Unexpected
and sudden vehicle movement
can occur if these precautions
are not followed in the order iden-
tified.
CAUTION
 To avoid damage to your transaxle, do not accelerate theengine in R (Reverse) or any for-ward gear position with thebrakes on.
 When stopped on an incline, do not hold the vehicle stationarywith engine power. Use the serv- ice brake or the parking brake.
 Do not shift from N (Neutral) or P (Park) into D (Drive), or R(Reverse) when the engine isabove idle speed.
WARNING
 Shifting into P (Park) while the vehicle is in motion will cause the
drive wheels to lock which will
cause you to lose control of the
vehicle.
 Do not use the P (Park) position in place of the parking brake.
Always make sure the shift lever
is latched in the P (Park) position
and set the parking brake fully.
 Never leave a child unattended in a vehicle.

R (Reverse)
Use this position to drive the vehicle
backward. N (Neutral)
The wheels and transaxle are not
engaged. The vehicle will roll freely even
on the slightest incline unless the parking
brake or service brakes are applied.
D (Drive)
This is the normal forward driving posi-
tion. The transaxle will automatically shift
through a 6-gear sequence, providing the
best fuel economy and power.
For extra power when passing another
vehicle or climbing grades, depress the
accelerator fully, at which time the
transaxle will automatically downshift to
the next lower gear.
✽ ✽
NOTICEAlways come to a complete stop before
shifting into D (Drive).
CAUTION
The transaxle may be damaged if
you shift into P (Park) while the vehicle is in motion.
CAUTION
Always come to a complete stopbefore shifting into or out of R(Reverse); you may damage thetransaxle if you shift into R(Reverse) while the vehicle is in motion, except as explained in“Rocking the vehicle” in this sec- tion.

Driving your vehicle
Ignition key interlock system The ignition key cannot be removed
unless the shift lever is in the P (Park)
position. If the ignition switch is in any
other position, the key cannot be
removed.
Good driving practices Never move the gear shift lever from P(Park) or N (Neutral) to any other posi-
tion with the accelerator pedal
depressed.
 Never move the gear shift lever into P (Park) when the vehicle is in motion.
 Be sure the car is completely stopped before you attempt to shift into R
(Reverse) or D (Drive).
 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.
 Do not "ride" the brakes. This can cause them to overheat and malfunc-
tion. Instead, when you 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.
 Slow down before shifting to a lower gear. Otherwise, the lower gear may
not be engaged.  Always use the parking brake. Do not
depend on placing the transaxle in P
(Park) to keep the car 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 the vehicle to go out of control.
 Optimum vehicle performance and economy is obtained by smoothly
depressing and releasing the accelera-
tor pedal.

Moving up a steep grade from a stand-
ing startTo move up a steep grade from a stand-
ing start, depress the brake pedal, shift
the shift lever to D (Drive). Depress the
accelerator gradually while releasing the
service brakes.
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 people or
objects.
WARNING
 Always buckle-up! In a collision, an unbelted occupant is signifi-
cantly more likely to be seriously
injured or killed than a properly
belted occupant.
 Avoid high speeds when corner- ing 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.
 In the event your vehicle leaves the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
 Never exceed posted speed lim- its.

521
Driving your vehicle
Power brakes Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event that the power-assisted
brakes lose power because of a stalled
engine or some other reason, you can
still stop your vehicle by applying greater
force to the brake pedal than you nor-
mally would. The stopping distance, how-
ever, will be longer.
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 neces-
sary to maintain steering control on slip-
pery surfaces.
In the event of brake failure If service brakes fail to operate while the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
BRAKE SYSTEM
WARNING
- Brakes
 Do not drive with your foot rest-ing on the brake pedal. This will
create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increased
stopping distances.
(Continued)
(Continued)
 When descending a long or steephill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brake
application will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
 Wet brakes may impair the vehi- cle’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 fashion after
driving through deep water. To
dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
 Always, confirm the position of the brake and accelerator pedal
before driving. If you don't check
the position of the accelerator
and brake pedal before driving,
you may depress the accelerator
instead of the brake pedal. It may
cause a serious accident.
WARNING
- Parking brake
Applying the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you must
use the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.

Driving your vehicle22
5Disc brakes wear indicator Your vehicle has disc brakes.
When your brake pads are worn and new
pads are required, you will hear a high-
pitched warning sound from your front
brakes or rear brakes. You may hear this
sound come and go or it may occur
whenever you depress the brake pedal.
Please remember that some driving con-
ditions or climates may cause a brake
squeal when you first apply (or lightly
apply) the brakes. This is normal and
does not indicate a problem with your
brakes.
Parking brake Applying the parking brake■ ■Foot type
To engage the parking brake, first apply
the foot brake and then depress the park-
ing brake pedal down as far as possible.
■ ■Hand type
To engage the parking brake, first apply
the foot brake and then pull up the park-
ing brake lever as far as possible.
In addition it is recommended that when
parking the vehicle on an incline, the shift
lever should be in the appropriate low
gear on manual transaxle vehicles or in
the P (Park) position on automatic
transaxle vehicles.
WARNING
- Brake wear
This brake wear warning sound
means your vehicle needs service.
If you ignore this audible warning,
you will eventually lose braking
performance, which could lead to a
serious accident.
CAUTION
 To avoid costly brake repairs, do not continue to drive with wornbrake pads.
 Always replace the front or rear brake pads as pairs.
