Brake Fluid
Checking the Brake Fluid
Level
B9002301
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the side
of the reservoir.
Before removing the reservoir cap and
adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If the level is low, add the specified brake
fluid to the MAX level. If the fluid level is
excessively low or frequent additions are
required have the brake system inspected
by an authorized HYUNDAI dealer.
WARNING If brake fluid comes in contact with your
eyes, flush your eyes with clean water for
at least 15 minutes and get immediate
medical attention.

Washer Fluid
Checking the Washer Fluid
Level
B9002701
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
climates to prevent freezing.
WARNING To prevent serious injury or death, take
the following safety precautions when
using washer fluid:
• Do not use coolant or antifreeze in the washer fluid reservoir. Coolant can
severely obscure visibility when
sprayed on the windshield and may
cause loss of vehicle control resulting in
an accident or damage to paint and
body trim.
• Do not allow sparks or flame to contact the washer fluid or the washer fluid
reservoir. Washer fluid may contain
alcohol and can be flammable.
• Do not drink washer fluid and avoid contact with skin. Washer fluid is
harmful to humans and animals.
• Keep washer fluid away from children and animals.

Cabin Air Filter
Filter Inspection
The cabin air filter must be replaced
according to the Maintenance Schedule.
If the vehicle is operated in severely
air-polluted cities or on dusty rough roads
for a long period, it should be inspected
more frequently and replaced sooner.
Replace the cabin air filter by following
the procedure below and be careful to
avoid damaging other components.

• Install a new cabin air filter with the arrow symbol (↓) facing down to
improve effectiveness.
• Always be sure that the front trunk cover is firmly closed after replacing
the cabin air filter.
Otherwise is may cause interior
damage in the motor compartment,
noise trouble, or entrance of foreign
substances.
Wiper Blades
Blade Inspection
Contamination of either the windshield or
the wiper blades with foreign matter can
reduce the effectiveness of the
windshield wipers.
Common sources of contamination are
insects, tree sap, and hot wax treatments
used by some commercial car washes. If
the blades are not wiping properly, clean
both the window and the blades with a
good cleaner or mild detergent, and rinse
thoroughly with clean water. Replace
blades as needed.

Battery Recharging
By battery charger
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged over a short time (because, for example, the
headlights or interior lights were left on
while the vehicle was not in use),
recharge it by slow charging (trickle) for
10 hours.
• If the battery gradually discharges because of high electrical load while the vehicle is being used, recharge it at
20-30 A for two hours.
WARNING Always follow these instructions when
recharging your vehicle’s battery to avoid
the risk of SERIOUS INJURY or DEATH
from explosions or acid burns:
• Before performing maintenance or
recharging the battery, turn off all
accessories and stop the vehicle.
• Keep all flames, sparks, or smoking materials away from the battery.
• Always work outdoors or in an area with plenty of ventilation.
• Wear eye protection when checking the battery during charging.
• The battery must be removed from the vehicle and placed in a well ventilated
area.
• Watch the battery during charging, and stop or reduce the charging rate if the
battery cells begin boiling violently.
• Remove the negative battery cable first and install it last when the battery is
disconnected. Disconnect the battery
charger in the following order:
1. Turn off the battery charger main switch.
2. Unhook the negative clamp from the negative battery terminal.
3. Unhook the positive clamp from the positive battery terminal.

By jump starting
After a jump start from a good battery,
drive the vehicle for 20-30 minutes
before it is shutoff. The vehicle may not
restart if you shut it off before the battery
had a chance to adequately recharge. For
more information, refer to the
“JumpStarting” section in chapter 8 for
more information on jump starting
procedures.

Information
An inappropriately disposed battery can be
harmful to the environment and human health.
Dispose of the battery according to your local
law(s) or regulation.

Reset Items
The following items may need to be reset
after the battery has been discharged or
the battery has been disconnected:
• Drive info/After Recharging/Accumulated info (items in
View modes) (refer to chapter 4)
• Integrated Memory System (refer to chapter 5)
• Power Windows (refer to chapter 5)

Tires and Wheels
WARNING Tire failure may cause loss of vehicle
control resulting in an accident. To
reduce risk of SERIOUS INJURY or
DEATH, take the following
precautions:
• Inspect your tires monthly for proper inflation as well as wear and
damage.
• The recommended cold tire pressure for your vehicle can be
found in this manual and on the tire
label located on the driver’s side
center pillar. Always use a tire
pressure gauge to measure tire
pressure. Tires with too much or
too little pressure wear unevenly
causing poor handling.
• Check the pressure of the spare every time you check the pressure
of the other tires on your vehicle.
• Replace tires that are worn, show uneven wear, or are damaged.
Worn tires can cause loss of braking
effectiveness, steering control, or
traction.
• ALWAYS replace tires with the same size, type, construction and
tread pattern as each tire that was
originally supplied with this vehicle.
Using tires and wheels other than
the recommended sizes could
cause unusual handling
characteristics, poor vehicle
control, or negatively affect your
vehicle’s Anti-Lock Brake System
(ABS) resulting in a serious
accident.
