Electric power steering (EPS)
The system assists you with steering
the vehicle. If the engine is off or if
the power steering system becomes
inoperative, the vehicle may still be
steered, but it will require increased
steering effort.
Also, the steering effort becomes
heavier as the vehicle’s speed
increases and becomes lighter as
the vehicle’s speed decreases for
better control of the steering wheel.
Should you notice any change in the
effort required to steer during normal
vehicle operation, we recommend
that the system be checked by an
authorized HYUNDAI dealer.
✽ ✽
NOTICE
The following symptoms may occur
during normal vehicle operation:
• The steering effort may be high
immediately after placing the igni-
tion switch in the ON position.
This happens as the system per-
forms the EPS system diagnostics.
When the diagnostics is complet-
ed, the steering wheel will return
to its normal condition.
• A click noise may be heard from the EPS relay after the ignition
switch is placed to the ON or
LOCK/OFF position.
• A motor noise may be heard when the vehicle is at stop or at a low
driving speed.
• When you operate the steering wheel in low temperature, abnor-
mal noise may occur. If tempera-
ture rises, the noise will disappear.
This is a normal condition.

CAUTION
If the Electric Power Steering
System does not operate nor-mally, the warning light ( ) willilluminate on the instrumentcluster. The steering wheel maybecome difficult to control oroperate. Take your vehicle to anauthorized HYUNDAI dealer andhave the system checked assoon as possible.

Once you set the ignition switch or Engine Start/Stop Button to the ON
position.
- It illuminates for approximately 3seconds
- 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 illuminateswith the parking brake released, it
indicates the brake fluid level 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 details,
refer to “Brake Fluid” in chapter 7). Then check all brake components
for fluid leaks. If any leak on the
brake system is found, the warning
light remains on, or the brakes do
not operate properly, do not drive
the vehicle.
In this case, have your vehicle
towed to an authorized HYUNDAI
dealer and inspected.
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 sys-
tems 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.
If the brakes fail while you are driv-
ing, shift to a lower gear for addition-
al engine braking and stop the vehi-
cle as soon as it is safe to do so.
WARNING - Parking
Brake & Brake Fluid
Warning Light
Driving the vehicle with a warn-
ing 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.

WARNING
Carbon monoxide (CO) gas is toxic. Breathing CO can cause unconsciousness and death.
Engine exhaust contains carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust inside the vehicle, open the windows immediately. Exposure to CO can cause
unconsciousness and death by asphyxiation.
Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose. If
you hear a change in the sound of the exhaust or if you drive over something that strikes the underneath side of the
vehicle, have the exhaust system checked as soon as possible by an authorized HYUNDAI dealer.
Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Run the engine only
long enough to start the engine and to move the vehicle out of the garage.
Avoid idling the engine for prolonged periods with people inside the vehicle.
If it is necessary to idle the engine for a prolonged period with people inside the vehicle , be sure to do so only in an
open area with the air intake set at "Fresh" and fan control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.
To assure proper operation of the ventilation system, keep the ventilation air intakes located in front of the windshield
clear of snow, ice, leaves, or other obstructions.
If you must drive with the trunk open:
Close all windows.
Open instrument panel air vents.
Set the air intake control at "Fresh", the air flow control at "Floor" or "Face", and the fan control set to high.
