If the brake fluid level in the reser-
voir is low:
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 (For more details,
refer to “Brake Fluid” in chapter 9).
Then check all brake components for
fluid leaks. If any leak on brake system
is still found, the warning light remains
on, or the brakes do not operate
properly, do not drive the vehicle.
In this case, we recommend that
you have the vehicle towed to an
authorized HYUNDAI dealer and
inspected.
Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking systems. This means
you still have braking on two wheels
even if one of the dual systems should
fail.
With only one of the dual systems
working, more than normal pedal travel
and greater pedal pressure are required
to stop the vehicle.
Also, the vehicle 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 vehicle as
soon as it is safe to do so.
WARNING
Parking Brake & Brake Fluid Warning
Light
Driving the vehicle with a warning light
ON is dangerous. If the Parking Brake &
Brake Fluid Warning Light illuminates
with the parking brake released, it
indicates that the brake fluid level is
low.
In this case, we recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer.
Anti-lock Brake System
(ABS) Warning Light
This warning light illuminates:
• Once you set the ignition switch or
Engine Start/Stop button to the ON
position.
- It illuminates for approximately 3
seconds and then goes off.
• When there is a malfunction with
the ABS (The normal braking system
will still be operational without the
assistance of the anti-lock brake
system).
In this case, we recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer.

This warning light illuminates:
• When you set the ignition switch or
Engine Start/Stop button to the ON
position.
- It illuminates for approximately 3
seconds and then goes off.
• When one or more of your tires
are significantly underinflated (The
location of the underinflated tires are
displayed on the LCD display).
For more details, refer to “Tire Pressure
Monitoring System (TPMS)” section in
chapter 8.
This warning light remains on after
blinking for approximately 60 seconds
or repeatedly blinks on and off at
approximately 3 second intervals:
• When there is a malfunction with the
TPMS.
In this case, we recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer as soon as
possible.
For more details, refer to “Tire Pressure
Monitoring System (TPMS)” section in
chapter 8.
WARNING

Driving your vehicle
Using the clutch (if equipped)
The clutch pedal should be depressed all
the way to the floor before:
- Starting the engine
The engine will not start without
depressing the clutch pedal.
- Shifting
To start your vehicle, slowly release
the clutch pedal and depress the
accelerator.
When releasing the clutch pedal, release
it slowly. The clutch pedal should always
be released while driving.
NOTICE
To prevent unnecessary wear or
damage to the clutch:
• Do not rest your foot on the clutch
pedal while driving.
• Do not hold the vehicle with the
clutch on an incline, while waiting for
the traffic light, etc.
• Always depress the clutch pedal
down fully to prevent noise or
damage.
• Do not start with the 2nd (second)
gear engaged except when you start
on a slippery road.
• Depress the clutch pedal all the way
and be careful not to depress the
pedal again before returning to the
upright position after you release
the pedal. If you depress the pedal
before returning to the original
position repeatedly, it may cause the
clutch system failure.
Downshifting
Downshift when you must slow down in
heavy traffic or drive up a steep hill to
prevent engine load.
Also, downshifting reduces the chance
of stalling and can accelerate when you
need to increase your speed again.
When the vehicle is going downhill,
downshifting helps maintain safe speed
by providing brake power from the
engine and enables less wear on the
brakes.
NOTICE
To prevent damage to the engine,
clutch and transmission:
• When downshifting from 5th
gear to 4th gear, be careful not to
inadvertently push the shift lever
sideways engaging the 2nd gear.
A drastic downshift may cause the
engine speed to increase to the point
the tachometer will enter the red-
zone.
• Do not downshift more than two
gear at a time or downshift the gear
when the engine is running at high
speed (5,000 RPM or higher). Such
a downshifting may damage the
engine, clutch and the transmission.

Good driving practices
• Never take the vehicle out of gear and
coast down a hill. This is extremely
dangerous.
• Don’t “ride” the brakes. This can
cause the brakes and related parts to
overheat and malfunction.
When you are driving down a long hill,
slow down and shift to a lower gear.
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
control of your vehicle.
• Be sure the vehicle is completely
stopped before you shift into R
(Reverse) to prevent damage to the
transmission.
• 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.
WARNING
Do not use the engine brake (shifting
from a higher gear to lower gear)
rapidly on slippery roads. The vehicle
may slip causing an accident.
WARNING
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 belted occupant.
• Avoid high speeds when cornering 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.
• HYUNDAI recommends you follow all
posted speed limits.

Driving your vehicle
Good driving practices
• Never take the vehicle out of gear and
coast down a hill. This is extremely
hazardous. Always leave the vehicle
in gear.
• Don’t “ride” the brakes. This can cause
them to overheat and malfunction.
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
control of your vehicle.
• Be sure the vehicle is completely
stopped before you attempt to shift
into reverse. The transmission can be
damaged if you do not.
• 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 significantly
more likely to be seriously injured
or killed than a properly belted
occupant.
• Avoid high speeds when cornering 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 oversteers 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 limits.

Transmission high temperature
• Under certain conditions, such as
repeated stop-and-go launches on
steep grades, sudden take off or
acceleration, or other harsh driving
conditions, the transmission clutch
temperatures will increase excessively.
• When the clutch is overheated, the
safe protection mode engages and the
gear position indicator on the cluster
blinks with a chime. At this time,
“Transmission temp. is high! Stop
safely” warning message will appear
on the LCD display and driving may
not be smooth.
• If this occurs, pull over to a safe
location, stop the vehicle with the
engine running, apply the brakes
and shift the vehicle to P (Park) with
engine on, and allow the transmission
to cool.
• If you ignore this warning, the driving
condition may become worse. You
may experience abrupt shifts, frequent
shifts, or jerkiness. To return to the
normal driving condition, stop the
vehicle and apply the foot brake or
shift into P (Park). Then allow the
transmission to cool for a few minutes
with engine on, before driving off.
• When possible, drive the vehicle
smoothly.

• If the vehicle continues to be driven
and the clutch temperatures reach
the maximum temperature limit, the
“Trans Hot! Park with engine on”
warning will be displayed. When this
occurs the clutch is disabled until the
clutch cools to normal temperatures.
• The warning will display a time to wait
for the transmission to cool.

• When the message “Trans cooled.
Resume driving.” appears you can
continue to drive your vehicle.
• When possible, drive the vehicle
smoothly.
If any of the warning messages in the
LCD display continue to blink, for your
safety, we recommend you contact an
authorized HYUNDAI dealer and have
the system checked.Transmission 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).
To shift from P (Park), you must depress
firmly on the brake pedal and make sure
your foot is off the accelerator pedal.
If you have done all of the above and
still cannot shift the lever out of P
(Park), see “Shift-Lock Release” in this
chapter.
The shift lever must be in P (Park) before
turning the engine off.
WARNING
• Shifting into P (Park) while the
vehicle is in motion may cause you to
lose control of the vehicle.
• After the vehicle has stopped, always
make sure the shift lever is in P (Park),
apply the parking brake, and turn the
engine off.
• When parking on an incline, block the
wheels to prevent the vehicle from
rolling down.
• For safety, always engage the parking
brake with the shift lever in the P
(Park) position except for the case of
emergency parking.

7-29

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.
WARNING
When you stay in the vehicle with
the engine running, be careful not to
depress the accelerator 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 flammable
materials, such as dry grass, paper or
leaves. They may ignite and cause a
fire.
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.
• Driving uphill or downhill, always shift
to D (Drive) when driving forward or to
R (Reverse) when driving backwards,
and check the gear position indicated
on the cluster before driving. If you
drive in the opposite direction of the
selected gear, the engine will turn
off and a serious accident might be
occurred due to the degraded brake
performance.
• 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 deceleration. 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 transmission in P (Park) to
keep the vehicle from moving.
