Maintenance
Parking brake
Inspect the parking brake system includ-
ing the parking brake pedal and cables.
Brake discs, pads, calipers and
rotors
Check the pads for excessive wear, discs
for run out and wear, and calipers for fluid
leakage.
Exhaust pipe and muffler
Visually inspect the exhaust pipes, muf-
fler and hangers for cracks, deterioration,
or damage. Start the engine and listen
carefully for any exhaust gas leakage.
Tighten connections or replace parts as
necessary.
Suspension mounting bolts
Check the suspension connections for
looseness or damage. Retighten to the
specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine off,
check for excessive free-play in the
steering wheel.
Check the linkage for bends or damage.
Check the dust boots and ball joints for
deterioration, cracks, or damage.
Replace any damaged parts.
Drive shafts and boots
Check the drive shafts, boots and clamps
for cracks, deterioration, or damage.
Replace any damaged parts and, if nec-
essary, repack the grease.
Air conditioning refrigerant
Check the air conditioning lines and con-
nections for leakage and damage.

WASHER FLUID
Checking the washer fluid level
The reservoir is translucent so that you
can check the level with a quick visual
inspection.
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. Plain
water may be used if washer fluid is not
available. However, use washer solvent
with antifreeze characteristics in cold cli-
mates to prevent freezing.
Checking the parking brake
Check whether the stroke is within spec-
ification when the parking brake pedal is
depressed with 44 lb (20 kg, 196 N) of
force. Also, the parking brake alone should
securely hold the vehicle on a fairly steep
grade. If the stroke is more or less than
specified, have the parking brake adjusted
by an authorized HYUNDAI dealer.
Stroke : 4~5 notch
WARNING -Coolant
Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
Radiator coolant can severely obscure visibility when sprayed
on the windshield and may cause
loss of vehicle control or damage
to paint and body trim.
Windshield washer fluid agents contain some amounts of alcohol
and can be flammable under cer-
tain circumstances. Do not allow
sparks or flame to contact the
washer fluid or the washer fluid
reservoir. Damage to the vehicle
or occupants could occur.
Windshield washer fluid is poi- sonous to humans and animals.
Do not drink and avoid contacting
windshield washer fluid. Serious
injury or death could occur.

LIGHT BULBS
Use only bulbs of the specified wattage.
✽
✽NOTICE
After heavy, driving rain or washing,
headlight and taillight lenses could
appear frosty. This condition is caused by
the temperature difference between the
lamp inside and outside. This is similar
to the condensation on your windows
inside your vehicle during the rain and
doesn’t indicate a problem with your
vehicle. If the water leaks into the lamp
bulb circuitry, have the vehicle checked
by an authorized HYUNDAI dealer.
WARNING - Working on
the lights
Prior to working on the light, firmly
apply the parking brake, ensure
that the engine start/stop button is
in the OFF position and turn off the
lights to avoid sudden movement
of the vehicle and burning your fin-
gers or receiving an electric shock.
CAUTION
Be sure to replace the burned-out
bulb with one of the same wattagerating. Otherwise, it may causedamage to the fuse or electricwiring system.CAUTION
If you don’t have necessary tools,the correct bulbs and the expertise,consult an authorized HYUNDAIdealer. In many cases, it is difficultto replace vehicle light bulbsbecause other parts of the vehicle must be removed before you canget to the bulb. This is especiallytrue if you have to remove the head-light assembly to
get to the bulb(s).
Removing/installingthe headlight
assembly can result in damage to the vehicle.
WARNING
When you replace the front head-
lamp bulb be careful of the HPCU
system, the high voltage cable
(orange color), and high voltage
components for the hybrid system.
It is very dangerous because the
HPCU has high voltage. Do not
touch high voltage systems or it
could result in the electric shock or
burns or even death.
CAUTION
If your vehicle is equipped withHigh Intensity Discharge (HID)headlights, these headlights con- tain mercury. So if you need to haveyour vehicle disposed, you shouldremove the HID Headlights before disposal. The removed HID head-lights should be recycled, re-used or disposed as hazardous waste.

Starting the engine
1. Carry the smart key or leave it insidethe vehicle.
2. Make sure the parking brake is firmly applied.
3. Place the shift lever in the P(Park) position. In N(Neutral) position, you
can not start the vehicle.
4. Depress the brake pedal.
5. Press the engine start/stop button.
6. In extremely cold weather or after the vehicle has not been operated for sev-
eral days, let the engine warm up with-
out depressing the accelerator.
Whether the engine is cold or warm, it
should be started without depressing
the accelerator.
if it is far away from you, the engine
may not start.
in the ACC or ON position, if any door
is open, the system checks for the
smart key. If the smart key is not in
the vehicle, the warning, "Key is not
in vehicle" will come on, and if all
doors are closed, the chime will also
sound for about 5 seconds. The indi-
cator will turn off while the vehicle is
moving. Keep the smart key in the
vehicle when using the ACC position
or if the vehicle engine is on. If the starting procedure is followed,
the "READY" symbol on the instru-
ment cluster will turn on. For more
details, please check Chapter 5.
ECONOMICAL and SAFE OPERA-
TION of Hybrid system
Drive smoothly. Accelerate at a moder-
ate rate and maintain a steady cruising
speed. Don't make "jack-rabbit" starts.
Don't race between stoplights.
Avoid heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid unnec-
essary braking. This also reduces
brake wear.
The regenerative brake generates energy when the vehicle decelerates.
When the hybrid battery power is low, the hybrid system automatically
recharges the hybrid battery.
When the engine runs in "N" position, the hybrid system can not generate
electricity. The hybrid battery cannot
recharge in "N" position. Please check
Chapter 5.
✽ ✽ NOTICE
In the hybrid system, the engine auto-
matically runs and stops. If the hybrid
system operates, the "READY" symbol
is illuminated.
In the following situation, the engine
may operate automatically.
- When the engine is ready to run
- When the hybrid battery is charged
- Depending on the temperature condi-
tion of the hybrid battery
STARTING THE HYBRID VEHICLE (SMART KEY)
WARNING
To avoid serious injury, turn off
ignition and be sure "READY" lamp
is off before working under hood.
Engine may start unexpectedly.
