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.

[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.

[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.

and may cause loss of vehicle control
resulting in an accident.
[Optimum vehicle performance
and fuel economy is obtained by
smoothly depressing and releasing the
accelerator.
WARNING
To reduce the risk of SERIOUS INJURY
or DEATH:

[ALWAYS wear your seat belt. 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.

Good braking practices
WARNING
Whenever leaving the vehicle or
parking, always come to a complete
stop and continue to depress the brake
pedal. Move the shift lever into the 1st
gear (for Manual transmission vehicle)
or N (Neutral) position (for Automatic
transmission/Dual clutch transmission
vehicle), then apply the parking brake,
and place the ignition switch in the
LOCK/OFF position.
Vehicles parked with the parking brake
not applied or not fully engaged may
roll inadvertently and may cause injury
to the driver and others. ALWAYS apply
the parking brake before exiting the
vehicle.Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it is
washed.
Your vehicle will not stop as quickly if
the brakes are wet. Wet brakes may
cause the vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns to
normal. If the braking action does not
return to normal, stop as soon as it is
safe to do so and we recommend that
you call a HYUNDAI authorised repairer
for assistance.
DO NOT drive with your foot resting on
the brake pedal. Even light, but constant
pedal pressure can result in the brakes
overheating, brake wear, and possibly
even brake failure.
If a tyre goes flat whilst you are driving,
apply the brakes gently and keep the
vehicle pointed straight ahead whilst you
slow down. When you are moving slowly
enough for it to be safe to do so, pull off
the road and stop in a safe location.
Keep your foot firmly on the brake pedal
when the vehicle is stopped to prevent
the vehicle from rolling forward.

Driving your vehicle
Hazardous driving conditions
When hazardous driving elements are
encountered such as water, snow,
ice, mud and sand, take the following
precautions:

[Drive cautiously and maintain a longer
braking distance.

[Avoid abrupt braking or steering.

[When your vehicle is stuck in snow,
mud, or sand, use the second
gear. Accelerate slowly to avoid
unnecessary wheel spin.

[Put sand, rock salt, tyre chains or
other non-slip materials under the
wheels to provide additional traction
whilst the vehicle becomes stuck in
ice, snow, or mud.
WARNING
Downshifting with an Automatic
transmission, whilst driving on slippery
surfaces can cause an accident. The
sudden change in tyre speed could
cause the tyres to skid. Be careful when
downshifting on slippery surfaces.
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 the
1st gear and R (Reverse, for manual
transmission vehicle) or R (Reverse)
and a forward gear (for Automatic
transmission vehicle/Dual clutch
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
whilst shifting, and press lightly on the
accelerator pedal whilst the transmission
is in gear. Slowly spinning the wheels in
forward and reverse directions causes
a rocking motion that may free the
vehicle.
WARNING
If the vehicle is stuck and excessive
wheel spin occurs, the temperature
in the tyres can increase very quickly.
If the tyres become damaged, a tyre
blow out or tyre explosion can occur.
This condition is dangerous - you and
others may be injured. Do not attempt
this procedure if people or objects are
anywhere near the vehicle.
If you attempt to free the vehicle, the
vehicle can overheat quickly, possibly
causing an engine compartment fire or
other damages. Try to avoid spinning
the wheels as much as possible to
prevent overheating of either the tyres
or the engine. DO NOT allow the vehicle
to spin the wheels above 35 mph (56
km/h).

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 tyre damage.
See “Towing” in chapter 8.
Smooth cornering
Avoid braking or gear changing in
corners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration.
Driving at night
Night driving presents more hazards
than driving in the daylight. Here are
some important tips to remember:

Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or on
slick pavement:

Driving on hills
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes so much
that they would get overheated and may
not operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 45 mph (70
km/h) to reduce the possibility of engine
and transmission overheating.
If your trailer weighs more than the
maximum trailer weight without trailer
brakes and you have an automatic
transmission/dual clutch transmission,
you should drive in D (Drive) when
towing a trailer. Operating your vehicle
in D (Drive) when towing a trailer will
minimise heat build-up and extend the
life of your transmission.
NOTICE
To prevent engine and/or transmission
overheating:

V When towing a trailer on steep
grades (in excess of 6%) pay close
attention to the engine coolant
temperature gauge to ensure the
engine does not overheat. If the
needle of the coolant temperature
gauge moves towards “H” (HOT),
pull over and stop as soon as it is
safe to do so, and allow the engine
to idle until it cools down. You may
proceed once the engine has cooled
sufficiently.

V You must decide your vehicle speed
according to the trailer weight and
uphill grade.
Parking on hills
Generally, if you have a trailer attached
to your vehicle, you should not park your
vehicle on a hill.
However, if you ever have to park your
trailer on a hill, here's how to do it:
1. Pull the vehicle into the parking space.
Turn the steering wheel in the
direction of the kerb (left if headed
down hill, right if headed up hill).
2. Shift the vehicle to P (Park, for
Automatic transmission/Dual clutch
transmission vehicle) or neutral (for
Manual transmission vehicle).
3. Set the parking brake and shut off the
vehicle.
4. Place wheel chocks under the trailer
wheels on the down hill side of the
wheels.
5. Start the vehicle, hold the brakes, shift
to neutral, release the parking brake
and slowly release the brakes until the
trailer chocks absorb the load.
6. Reapply the brakes and parking
brakes.
7. Move the shift lever to P (Park, for
Automatic transmission/Dual clutch
transmission vehicle) or the 1st gear
when the vehicle is parked on a uphill
grade and in R (Reverse) on a downhill
(for Manual transmission vehicle).
8. Shut off the vehicle and release the
vehicle brakes but leave the parking
brake set.
WARNING
To prevent serious or fatal injury:
Do not get out of the vehicle without
the parking brake firmly set. If you have
left the engine running, the vehicle can
move suddenly. You and others could
be seriously or fatally injured.

6-72
Driving your vehicle
Ready to leave after parking on a
hill
1. With the shift lever to P (Park, for
Automatic transmission/Dual clutch
transmission vehicle) or neutral (for
Manual transmission vehicle), apply
your brakes and hold the brake pedal
down whilst you:

V Start your engine;

V Shift into gear; and

V Release the parking brake.
2. Slowly remove your foot from the
brake pedal.
3. Drive slowly until the trailer is clear of
the chocks.
4. Stop and have someone pick up and
store the chocks.
Maintenance when towing a
trailer
Your vehicle will need service more
often when you regularly pull a trailer.
Important items to pay particular
attention to include engine oil,
automatic transmission/dual clutch
transmission fluid, axle lubricant and
cooling system fluid. Brake condition
is another important item to frequently
check. If you’re trailering, it’s a good
idea to review these items before
you start your trip. Don’t forget to
also maintain your trailer and towbar.
Follow the maintenance schedule that
accompanied your trailer and check it
periodically. Preferably, conduct the
check at the start of each day’s driving.
Most importantly, all towbar nuts and
bolts should be tight.
NOTICE
To prevent vehicle damage:

V Due to higher load during trailer
usage, overheating might occur on
hot days or during uphill driving. If
the coolant gauge indicates over-
heating, switch off the air conditioner
and stop the vehicle in a safe area to
cool down the engine.

V When towing check Automatic
transmission/Dual clutch
transmission fluid more frequently.

V If your vehicle is not equipped with
an air conditioner, you should install
a condenser fan to improve engine
performance when towing a trailer.

8-9
08
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 P (Park, for
automatic transmission/dual clutch
transmission vehicle) or neutral (for
manual transmission/dual clutch
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 bonnet, stop the engine. Do
not open the bonnet 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
Whilst 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 a HYUNDAI
authorised repairer for assistance.
WARNING
NEVER remove the radiator
cap or the drain plug whilst
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 whilst 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.
