Driving your 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.
• 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.
• 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.
• 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.
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.

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 distance, 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 control
on slippery surfaces.
WARNING
Take the following precautions:
• Do not drive with your foot resting
on the brake pedal. This will create
abnormal high brake temperatures,
excessive brake lining and pad wear,
and increased stopping distances.
• When descending a long or steep
hill, shift to a lower gear and avoid
continuous application of the brakes.
Applying the brakes continuously
will cause the brakes to overheat and
could result in a temporary loss of
braking performance.
• 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 fashion after driving
through deep water. To dry the
brakes, lightly tap the brake pedal to
heat up the brakes while maintaining
a safe forward speed until brake
performance returns to normal.
Avoid driving at high speeds until the
brakes function correctly.
Disc brakes wear indicator
When your brake pads are worn and new
pads are required, you will hear a high
pitched warning sound from your front
or rear brakes. You may hear this sound
come and go or it may occur whenever
you depress the brake pedal.
Please remember some driving
conditions 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.
NOTICE
To avoid costly brake repairs, do not
continue to drive with worn brake pads.
i Information
Always replace brake pads as complete
front or rear axle sets.
BRAKING SYSTEM

7-39
07
• NEVER allow anyone who is
unfamiliar with the vehicle to touch
the parking brake. If the parking
brake is released unintentionally,
serious injury may occur.
• Only release the parking brake when
you are seated inside the vehicle with
your foot firmly on the brake pedal.
NOTICE
• Do not apply the accelerator pedal
while the parking brake is engaged.
If you depress the accelerator pedal
with the parking brake engaged,
warning will sound. Damage to the
parking brake may occur.
• Driving with the parking brake on
can overheat the braking system and
cause premature wear or damage to
brake parts. Make sure the parking
brake is released and the Brake
Warning Light is off before driving.
Parking brake warning light
Check the Parking Brake
Warning Light by placing the
ignition switch to the ON
position (do not start the
engine).
This light will be illuminated when the
parking brake is applied with the ignition
switch in the START or ON position.
Before driving, be sure the parking brake
is released and the Brake Warning Light
is OFF.
If the Parking Brake Warning Light
remains on after the parking brake is
released while the engine is running,
there may be a malfunction in the
brake system. Immediate attention is
necessary.
If at all possible, cease driving the
vehicle immediately. If that is not
possible, use extreme caution while
operating the vehicle and only continue
to drive the vehicle until you can reach a
safe location.

Driving your vehicle
Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice,
mud or sand:
Drive cautiously and allow extra distance
for braking.
Avoid sudden movements in braking or
steering.
If stuck in snow, mud, or sand, use
second gear. Accelerate slowly to avoid
spinning the drive wheels.
WARNING
Downshifting with an Automated
manual transmission, while driving
on slippery surfaces can cause an
accident. The sudden change in tire
speed could cause the tires to skid. Be
careful when downshifting on slippery
surfaces.
Use sand, rock salt, or other non-slip
material under the drive wheels to
provide traction when stalled in ice,
snow, or mud.
Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first
turn the steering wheel right and left
to clear the area around your front
wheels. Then, shift back and forth
between 1st and R (Reverse, for manual
transmission vehicle) or R (Reverse) and
a forward gear (for Automated manual
transmission vehicle). Try to avoid
spinning the wheels, and do not race the
engine.
To prevent transmission wear, wait until
the wheels stop spinning before shifting
gears. Release the accelerator pedal
while shifting, and press lightly on the
accelerator pedal while the transmission
is in gear. Slowly spinning the wheels in
forward and reverse directions causes
a rocking motion that may free the
vehicle.
NOTICE
If the tires spin at high speed the tires
can explode, and you or others may be
injured. Do not attempt this procedure
if people or objects are anywhere near
the vehicle.
The vehicle can overheat causing an
engine compartment fire or other
damage. Spin the wheels as little as
possible and avoid spinning the wheels
at speeds over 56 km/h (35 mph) as
indicated on the speedometer.
NOTICE
If you are still stuck after rocking the
vehicle a few times, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating, possible damage
to the transmission, and tire damage.
See “Towing” in chapter 8.

If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Place the shift lever in N (Neutral,
for Automated manual transmission
vehicle) or neutral (for manual
transmission vehicle) and set the
parking brake. If the air conditioning is
ON, turn it OFF.
3. If engine coolant is running out under
the vehicle or steam is coming out
from the hood, stop the engine. Do
not open the hood until the coolant
has stopped running or the steaming
has stopped. If there is no visible
loss of engine coolant and no steam,
leave the engine running and check
to be sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off.
WARNING
While the engine is running,
keep hands, clothing and
tools away from the moving
parts such as the cooling
fan and drive belt to
prevent serious injury.4. Check for coolant leaking from the
radiator, hoses or under the vehicle. (If
the air conditioning had been in use, it
is normal for cold water to be draining
from it when you stop.)
5. If engine coolant is leaking out,
stop the engine immediately and
we recommend that you call an
authorized HYUNDAI dealer for
assistance.
WARNING
NEVER remove the radiator
cap or the drain plug while
the engine and radiator are
hot. Hot coolant and steam
may blow out under
pressure, causing serious injury.
Turn the engine off and wait until the
engine cools down. Use extreme care
when removing the radiator cap. Wrap
a thick towel around it, and turn it
counterclockwise slowly to the first
stop. Step back while the pressure
is released from the cooling system.
When you are sure all the pressure
has been released, press down on the
cap, using a thick towel, and continue
turning counterclockwise to remove it.
IF THE ENGINE OVERHEATS

9-8
Emergency situations
6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to normal.
Then, if coolant has been lost,
carefully add coolant to the reservoir
to bring the fluid level in the reservoir
up to the halfway mark.
7. Proceed with caution, keeping alert
for further signs of overheating.
If overheating happens again,
we recommend that you call an
authorized HYUNDAI dealer for
assistance.
NOTICE
• Serious loss of coolant indicates a
leak in the cooling system and we
recommend the system be checked
by an authorized HYUNDAI dealer.
• When the engine overheats from
low engine coolant, suddenly adding
engine coolant may cause cracks
in the engine. To prevent damage,
add engine coolant slowly in small
quantities.

9-10
Emergency situations
Tire pressure monitoring system
WARNING
Over-inflation or under-inflation can
reduce tire life, adversely affect vehicle
handling, and lead to sudden tire
failure that may cause loss of vehicle
control resulting in an accident.
Each tire, including the spare (if
provided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label. (If your
vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure label,
you should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your tires is
significantly under-inflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and
check your tires as soon as possible,
and inflate them to the proper pressure.
Driving on a significantly under-inflated
tire causes the tire to overheat and can
lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low
tire pressure telltale.Your vehicle has also been equipped
with a TPMS malfunction indicator
to indicate when the system is
not operating properly. The TPMS
malfunction indicator is combined with
the low tire pressure telltale. When
the system detects a malfunction, the
telltale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as
long as the malfunction exists. When
the malfunction indicator is illuminated,
the system may not be able to detect
or signal low tire pressure as intended.
TPMS malfunctions may occur for
a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that
prevent the TPMS from functioning
properly. Always check the TPMS
malfunction telltale after replacing
one or more tires or wheels on your
vehicle to ensure that the replacement
or alternate tires and wheels allow the
TPMS to continue to function properly.
i Information
If the TPMS indicator does not illuminate
for 3 seconds when the ignition switch
is turned to the ON position or engine
is running, or if it comes on after
blinking for approximately one minute,
we recommend that you contact an
authorized HYUNDAI dealer.

Maintenance
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is filled
at the factory.
Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season, and
before traveling to a colder climate.
NOTICE
• Do not drive with no engine coolant.
It may cause water pump failure and
engine seizure, etc.
• When the engine overheats from
low engine coolant, suddenly adding
engine coolant may cause cracks
in the engine. To prevent damage,
add engine coolant slowly in small
quantities.
Checking the coolant level
OBI3090008OBI3090008
„„Petrol Engine (1.0 T-GDi)Petrol Engine (1.0 T-GDi)
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen or
deteriorated hoses.
The coolant level should be filled
between F (Full) and L (Low) marked on
the side of the coolant reservoir when
the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water.
Bring the level to F (Full), but do
not overfill. If frequent additions are
required, we recommend that the
system be inspected by an authorized
HYUNDAI dealer.
