Driving your vehicle
VSM detects the distance from the vehi-
cle ahead with the sensor, to warn you
before collision and protect you in certain
hazardous situations. If the VSM senses the object ahead too
near the vehicle and if driver's operat-
ing of the brake pedal or the steering
wheel should be needed, the warning
light illuminates.
Immediately reduce your speed.
If the VSM senses more dangerous, the warning sound also operates and
the seat belt vibrates.
Immediately reduce your speed.
Brake operating
If the VSM senses the collision, thebrake system comes to standard mode
to react promptly when the driver oper-
ates the brake pedal.
If the driver releases the accelerator after warning in hazardous situations,
the VSM automatically brakes the vehi-
cle gently.
If the driver hits the brake to reduce vehicle speed, the brake assistant sys-
tem operates to raise efficiency of
braking.
If danger disappears, if the driver depresses the accelerator or if the driv-
er releases the brake pedal, the brake
operating stop.
VEHICLE STABILITY MANAGEMENT (VSM) (IF EQUIPPED)
CAUTION
Always check the road conditions
to prevent danger even if the warn-ing light does not illuminate, the
warning sound does not operate or the seat belt does not vibrate.
OVI059059OVI059064L
WARNING
The VSM does not stop the vehicle
completely and does not avoid col-
lision. Always look ahead cautious-
ly to prevent unexpected and sud-
den situations from occurring.

Driving your vehicle
Remember, your vehicle does notrequire extended warm-up. After the
engine has started, allow the engine to
run for 10 to 20 seconds prior to plac-
ing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warm-up period.
Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in too high
a gear resulting in the engine bucking.
If this happens, shift to a lower gear.
Over-revving is racing the engine
beyond its safe limit. This can be avoid-
ed by shifting at the recommended
speeds. Use your air conditioning sparingly.
The air conditioning system is operat-
ed by engine power so your fuel econ-
omy is reduced when you use it.
Open windows at high speeds can reduce fuel economy.
Fuel economy is less in crosswinds and headwinds. To help offset some of
this loss, slow down when driving in
these conditions.
Keeping a vehicle in good operating con-
dition is important both for economy and
safety. Therefore, have an authorized
HYUNDAI dealer perform scheduled
inspections and maintenance.
WARNING - Engine off dur-
ing motion
Never turn the engine off to coast
down hills or anytime the vehicle is
in motion. The power steering and
power brakes will not function
properly without the engine run-
ning. Instead, keep the engine on
and downshift to an appropriate
gear for engine braking effect. In
addition, turning off the ignition
while driving could engage the
steering wheel lock resulting in
loss of vehicle steering which
could cause serious injury ordeath.

Driving your vehicle
✽✽NOTICE
The ESP system should be turned OFF
prior to rocking the vehicle.
Smooth cornering
Avoid braking or gear changing in cor-
ners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration. If you follow
these suggestions, tire wear will be held
to a minimum. Driving at night
Because night driving presents more
hazards than driving in the daylight, here
are some important tips to remember:
Slow down and keep more distance
between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.
WARNING - Spinning tires
Do not spin the wheels, especially at speeds more than 56 km/h (35
mph). Spinning the wheels at high
speeds when the vehicle is station-
ary could cause a tire to overheat
which could result in tire damage
that may injure bystanders.
OVI059045
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 of backward as it
becomes unstuck, causing injury
or damage to nearby people orobjects.

ROAD WARNING
Hazard warning flasher
The hazard warning flasher serves as a
warning to other drivers to exercise
extreme caution when approaching,
overtaking, or passing your vehicle. It should be used whenever emergency
repairs are being made or when the vehi-cle is stopped near the edge of a road-
way.
Depress the flasher switch with the
engine start/stop button in any position.
The flasher switch is located in the cen-
ter console switch panel. All turn signal
lights will flash simultaneously.
• The hazard warning flasher operates
whether your vehicle is running or not.
The turn signals do not work when the hazard flasher is on.
Care must be taken when using the hazard warning flasher while the vehi-
cle is being towed. If the engine stalls at a crossroad
or crossing If the engine stalls at a crossroad or
crossing, set the shift lever in the N
(Neutral) position and then push the vehi-
cle to a safe place.
If you have a flat tire while driving
If a tire goes flat while you are driving:
1. Take your foot off the accelerator pedal
and let the vehicle slow down while
driving straight ahead. Do not apply the
brakes immediately or attempt to pull
off the road as this may cause a loss of
control. When the vehicle has slowed
to such a speed that it is safe to do so,
brake carefully and pull off the road.
Drive off the road as far as possible
and park on a firm level ground. If you
are on a divided highway, do not park
in the median area between the two
traffic lanes.
2. When the vehicle is stopped, turn on your emergency hazard flashers, set
the parking brake and put the shift
lever in P.
3. Have all passengers get out of the vehicle. Be sure they all get out on the
side of the vehicle that is away from
traffic.

Do not use any tire sealant ifyour vehicle is equipped witha Tire Pressure MonitoringSystem. The liquid sealant candamage the tire pressure sen- sors.
In order to correctly monitor the tires with inflation, the 4tire pressure monitoring sen-sors should be exactly fitted to each of the 4 driven wheel.There should be no other sen-sors in the vehicle include spare tire, it may cause thesystem couldn’t monitor thetires with inflation correctly.
WARNING - Protecting
TPMS
Tampering with, modifying, or
disabling the Tire PressureMonitoring System (TPMS)
components may interfere withthe system's ability to warn the
driver of low tire pressure con-
ditions and/or TPMS malfunc-
tions. Tampering with, modify-
ing, or disabling the TirePressure Monitoring System
(TPMS) components may void
the warranty for that portion of
the vehicle.WARNING - TPMS
The TPMS cannot alert you to severe and sudden tire dam-
age caused by external fac-
tors such as nails or roaddebris.

What to do in an emergency
7. Place the jack at the front or rearjacking position closest to the tire
you are changing. Place the jackat the designated locations under
the frame. The jacking positions
are plates welded to the frame
with two tabs and a raised dot to
index with the jack. 8. Insert the jack handle into the jack
and turn it clockwise, raising the
vehicle until the tire just clears the
ground. This measurement is
approximately 30 mm (1.2 in).
Before removing the wheel lug
nuts, make sure the vehicle is sta-
ble and that there is no chance for
movement or slippage. 9. Loosen the wheel nuts and
remove them with your fingers.Slide the wheel off the studs and
lay it flat so it cannot roll away. To
put the wheel on the hub, pick up
the spare tire, line up the holeswith the studs and slide the wheel
onto them. If this is difficult, tip thewheel slightly and get the top holein the wheel lined up with the top
stud. Then jiggle the wheel back
and forth until the wheel can be
slid over the other studs.
WARNING - Jack location
To reduce the possibility of
injury, be sure to use only the
jack provided with the vehicle
and in the correct jack position;
never use any other part of the
vehicle for jack support.
