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 vehicle turned off, check the brake fluid level immediately and add
fluid as required (For more details,
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. We recommend that
you 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 are 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.
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, we recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer.

Instrument cluster
4-10
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.
In this case, drive safely and we
recommend that you 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.
Anti-lock Brake System (ABS)
Warning Light
This warning light illuminates:
•
When the START/STOP button is in the ON position.
- It illuminates for approximately 3 seconds and then goes off.
• When there is a malfunction with
the ABS (The normal braking system
will still be operational without the
assistance of the anti-lock brake
system).
In this case, we recommend that
you have the vehicle inspected by an
authorized HYUNDAI dealer. 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, we recommend that
you 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.
We recommend you 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, we recommend you have the vehicle inspected by an authorized
HYUNDAI dealer as soon as possible.

NOTICE
When using tire chains: • Wrong size chains or improperly
installed chains can damage your
vehicle’s brake lines, suspension, body and wheels.
• Use SAE “S” class or wire chains.
• If you hear noise caused by chains
contacting the body, retighten the
chain to prevent contact with the
vehicle body.
• To prevent body damage, retighten
the chains after driving 0.5~1.0 km
(0.3~0.6 miles).
• Do not use tire chains on vehicles
equipped with aluminum wheels. If
unavoidable, use a wire type chain.
• Use wire chains less than 12 mm (0.47
in) wide to prevent damage to the
chain’s connection.
Winter Precautions
Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery and
cables, as specified in the chapter 9. The battery charging level can be
checked by an authorized HYUNDAI
dealer or in a service station.
Change to “winter weight” oil if
necessary
In some regions during winter, it is
recommended to use the “winter
weight” oil with lower viscosity. For
further information, refer to the chapter
2. When you are not sure about a type
of winter weight oil, we recommend to
consult an authorized HYUNDAI dealer.
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.

OWNER MAINTENANCE
WARNING
Performing maintenance work on a
vehicle can be dangerous. If you lack
sufficient knowledge and experience
or the proper tools and equipment to
do the work, we recommend that the
system be serviced by an authorized
HYUNDAI dealer. ALWAYS follow
these precautions for performing
maintenance work: • Park your vehicle on level ground,
shift to P (Park) position, apply the
parking brake, place the START/STOP
button in the OFF position.
• Block the tires (front and back) to
prevent the vehicle from moving.
Remove loose clothing or jewelry
that can become entangled in
moving parts.
• Keep flames, sparks, or smoking
materials away from the battery and
motor related parts.
The following lists are vehicle checks and
inspections that should be performed
by the owner or an authorized HYUNDAI
dealer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as soon as possible.
These Owner Maintenance vehicle
checks are generally not covered by
warranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for charging: • Check the coolant level in the coolant
reservoir.
• Check the windshield washer fluid
level.
• Check for low or under-inflated tires.
WARNING
Be careful when checking your coolant
level when the motor compartment is
hot. This may result in coolant being
blown out of the opening and cause
serious burns and other injuries.
