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.

[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.
[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.

Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
If the engine is not running or is turned
off whilst 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 down a long or
steep hill, downshift to a lower
gear in order to control your
speed without using the brake
pedal excessively. 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 whilst 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.
Note that 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.

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:

could be temporarily blinded, and it
will take several seconds for your eyes
to readjust to the darkness.
Driving in the rain
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 your vehicle
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the water.
The best advice is SLOW DOWN when
the road is wet.
The risk of hydroplaning increases as
the depth of tyre tread decreases, refer
to “Tyre replacement” in chapter 9.
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them several
times whilst the vehicle is moving
slowly.
Highway driving
Tyres
Adjust the tyre inflation, as specified.
Under-inflation may overheat or damage
the tyres.
Do not install worn-out or damaged
tyres, which may reduce traction or fail
the braking operation.

Fuel, engine coolant and engine oil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine
coolant level and the engine oil before
driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.

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.
