Seat Belt Warning Light
This warning light informs the driver that the seat belt is not fastened.
For more information, refer to “Seat
Belts” in chapter 3.
Parking Brake & Brake Fluid
Warning Light
This warning light illuminates:
• When you place the ignition switch to
the ON position.
-The parking brake light illuminates
for about 3 seconds and will then
turn off once the parking brake is
released.
• Whenever the parking brake is
applied.
• Whenever the brake fluid level in the
reservoir is low.
-If the warning light illuminates
with the parking brake released, it
indicates that the brake fluid level in
the reservoir is low.
If the brake fluid level in the reservoir is
low:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the engine stopped, check
the brake fluid level immediately
and add fluid as required (For more
information, refer to "Brake Fluid" in
chapter 9). After adding brake fluid,
check all brake components for fluid
leaks. If a brake fluid leak is found, or
if the warning light remains on, or if
the brakes do not operate properly, do
not drive the vehicle. Have the vehicle
inspected by an authorized HYUNDAI
dealer. Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking systems. This means
you still have braking on two wheels even
if one of the dual systems should fail.
With only one of the dual systems
working, more than normal pedal travel
and greater pedal pressure is required to
stop the vehicle.
If the brakes fail while you are driving,
shift to a lower gear for additional engine
braking and stop the vehicle as soon as it
is safe to do so.
WARNING
Parking Brake & Brake Fluid Warning
Light
Driving the vehicle with a warning light
ON is dangerous. If the Parking Brake &
Brake Fluid Warning Light illuminates
with the parking brake released, it
indicates that the brake fluid level is
low.
In this case, have the vehicle inspected
by an authorized HYUNDAI dealer.
Regenerative brake warning
light
(yellow)
This warning light illuminates:
When the regenerative brake does not
operate and the brake does not perform
well. This causes the Brake Warning
light (red) and Regenerative Brake
Warning Light (yellow) to illuminate
simultaneously.
If this occurs, drive safely and we
recommend that you have the vehicle
inspected by an authorized HYUNDAI
dealer.
The operation of the brake pedal may
be more difficult than normal and the
braking distance may increase.

Instrument Cluster
4-12
Anti-lock Brake System (ABS)
Warning Light
This warning light illuminates:
• When you place the ignition switch to
the ON position.
-The ABS warning light illuminates
for about 3 seconds and then turns
off.
• Whenever there is a malfunction with
the ABS.
Note that the hydraulic braking
system will still be operational even if
there is a malfunction with the ABS.
Electronic Brake Force
Distribution (EBD) System
Warning Light
These two warning lights illuminate at the same time while driving:
When the ABS and regular brake system
may not work normally.
In this case, have the vehicle inspected
by an authorized HYUNDAI dealer.
WARNING
Electronic Brake Force Distribution
(EBD) System Warning Light
When both ABS and Parking Brake &
Brake Fluid Warning Lights are on, the
brake system will not work normally
and you may experience an unexpected
and dangerous situation during sudden
braking.
In this case, avoid high speed driving
and abrupt braking.
Have the vehicle inspected by an
authorized HYUNDAI dealer as soon as
possible.
Information - Electronic Brake
Force Distribution (EBD)
System Warning Light
When the ABS Warning Light is on
or both ABS and Parking Brake &
Brake Fluid Warning Lights are on, the
speedometer, odometer, or tripmeter may
not work. Also, the EPS Warning Light
may illuminate and the steering effort may
increase or decrease.
In this case, have the vehicle inspected by
an authorized HYUNDAI dealer as soon
as possible.
Electronic Parking Brake
(EPB) Warning Light
(if equipped)
EPB
This warning light illuminates:
• When you place the Engine Start/Stop
button to the ON position.
-The EPB warning light illuminates
for approximately 3 seconds and
then turns off.
• Whenever there is a malfunction with
the EPB.
If this occurs, have the vehicle
inspected by an authorized HYUNDAI
dealer.
Information
The Electronic Parking Brake (EPB)
Warning Light may illuminate when
the Electronic Stability control (ESC)
Indicator Light comes on to indicates that
the ESC is not working properly (This
does not indicate malfunction of the EPB).

Winter Precautions
Use high quality ethylene glycol
coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because it
helps prevent corrosion in the cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 8. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
Change to "winter weight" oil if
necessary
In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See chapter 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the
battery and cables as described in
chapter 8. The level of charge in your
battery can be checked by an authorized
HYUNDAI dealer or a service station.
Check spark plugs and ignition
system
Inspect your spark plugs as described in
chapter 8 and replace them if necessary.
Also check all ignition wiring and
components to be sure they are not
cracked, worn or damaged in any way.
Use approved window washer anti-
freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the
container. Window washer anti-freeze is available
from an authorized HYUNDAI dealer
and most auto parts outlets. Do not
use engine coolant or other types of
antifreeze as these may damage the
paint finish.
Do not let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when
there is an accumulation of snow or
ice around or near the rear brakes or
if the brakes are wet. If there is a risk
the parking brake may freeze, apply
it only temporarily while you put the
gear selector lever in P and block the
rear wheels so the car cannot roll. Then
release the parking brake.
Do not let ice and snow accumulate
underneath
Under some conditions, snow and ice
can build up under the fenders and
interfere with the steering. When driving
in severe winter conditions where this
may happen, you should periodically
check underneath the car to be sure the
movement of the front wheels and the
steering components is not obstructed.
Don't place foreign objects
or materials in the engine
compartment
Placement of foreign object or materials
which prevent cooling of the engine, in
the engine compartment, may cause a
failure or combustion. The manufacturer
is not responsible for the damage caused
by such placement.
To keep locks from freezing
To keep the locks from freezing, squirt
an approved de-icer fluid or glycerine
into the key opening. If a lock is covered
with ice, squirt it with an approved de-
icing fluid to remove the ice. If the lock
is frozen internally, you may be able to
thaw it out by using a heated key. Handle
the heated key with care to avoid injury.
