Air bag warning light
This warning light illuminates:
•
When you set the Start/Stop button to the ON position.
- The air bag warning light illuminates for about 6 seconds and then turns
off when all checks have been
performed.
• The air bag warning light will remain
illuminated if there is a malfunction
with the Safety Restraint System (SRS)
air bag operation.
If this occurs, have the vehicle
inspected by an authorized HYUNDAI
dealer.
Regenerative brake warning
light
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.
In this case, drive safely and have your
vehicle inspected by an authorized
HYUNDAI dealer.
The operation of the brake pedal may
be more difficult than normal and the
braking distance can increase. Parking brake & brake fluid
warning light
This warning light illuminates:
•
When you set the START/STOP button in the ON position.
- It illuminates for approximately 3 seconds.
- It remains on if the parking brake is applied.
• When the parking brake is applied.
• When the brake fluid level in the
reservoir is low.
- If the warning light illuminates with the parking brake released, it
indicates the brake fluid level in the
reservoir is low.
• When the regenerative brake does not
operate.
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 motor stopped, check the brake fluid level immediately and add
fluid as required (For more details,
refer to “Brake Fluid” section 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 system. 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.
Also, the vehicle will not stop in as short
a distance with only a portion of the
brake system working.
If the brakes fail while you are driving,
shift to a lower gear for additional vehicle
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.
If this occurs, have the vehicle
inspected by an authorized HYUNDAI
dealer. Anti-lock Brake System (ABS)
warning light
This warning light illuminates:
•
When you set the Start/Stop button to the ON position.
- The ABS warning light illuminates for about 3 seconds and then goes
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.
If this occurs, have the vehicle
inspected by an authorized HYUNDAI
dealer.
Electronic Brake Force
Distribution (EBD) system
warning light
When the ABS warning and
Parking Brake warning lights are on
simultaneously, it may indicate a
problem with the Electronic Brake Force
Distribution system.
If this occurs, 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.
If this occurs, avoid high speed driving
and abrupt braking.
Have the vehicle inspected by an
authorized HYUNDAI dealer as soon as possible.
NOTICE
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.
If this occurs, have the vehicle
inspected by an authorized HYUNDAI dealer as soon as possible. Electric Power Steering (EPS)
warning light
This warning light illuminates:
•
When you set the Start/Stop button to the ON position.
- The electric powering steering warning light illuminates for about 3
seconds and then goes off.
• Whenever there is a malfunction with
the electric power steering.
If this occurs, have the vehicle
inspected by an authorized HYUNDAI
dealer.
Master warning light
This warning light illuminates:
When there is a malfunction in operation
in any of the following systems: - Forward Collision-Avoidance Assist malfunction (if equipped)
- Forward Collision-Avoidance Assist radar blocked (if equipped)
- Blind-Spot Collision Warning malfunction (if equipped)
- Blind-Spot Collision Warning radar blocked (if equipped)
- LED headlamp malfunction (if equipped)
- High Beam Assist malfunction (if equipped)
- Smart Cruise Control malfunction (if equipped)
- Smart Cruise Control radar blocked (if equipped)
- Tire Pressure Monitoring System (TPMS) malfunction
To identify the details of the warning,
look at the LCD display.

Winter Precautions
Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery and
cables, as specified in chapter 9. The
battery charging level can be checked
by an authorized HYUNDAI dealer or in a
service station.
To prevent locks from freezing
To prevent the locks from being frozen,
spray approved de-icing fluid or glycerin
into key holes. When a lock opening is
already covered with ice, spray approved
de-icing fluid over the ice to remove it.
When an internal part of a lock freezes,
try to thaw it with a heated key. Carefully
use the heated key to avoid an injury.
Use approved window washer anti-
freeze solution in system
To prevent the window washer from
being frozen, add authorized window
washer anti-freeze solution, as specified
on the window washer container.
Window washer anti-freeze solution is
available from an authorized HYUNDAI
dealer, and most vehicle accessory
outlets. Do not use coolant or other types
of anti-freeze solution, to prevent any
damage to the vehicle paint. 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. When there is the risk that your
parking brake may freeze, temporarily
apply it with the gear in P (Park). Also,
block the rear wheels in advance, so the
vehicle may not 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 such conditions during the severe
winter, you should check underneath
the vehicle on a regular basis, to ensure
that the front wheels and the steering
components is unblocked.
Carry emergency equipment
In accordance with weather conditions,
you should carry appropriate emergency
equipment, while driving. Some of the
items you may want to carry include tire
chains, tow straps or chains, flashlight,
emergency flares, sand, shovel, jumper
cables, window scraper, gloves, ground
cloth, coveralls, blanket, etc.
Do not place objects or materials in the
motor compartment
Putting objects or materials in the motor
compartment may cause an motor
failure. Such damage will not be covered
by the manufacturer’s warranty.
