(Continued)
Use only approved portable plas-
tic fuel containers designed to
carry and store gasoline.
• Do not use cellular phones while
refueling. Electric current and/or
electronic interference from cel-
lular phones can potentially
ignite fuel vapors causing a fire.
• When refueling, always shut the
engine off. Sparks produced by
electrical components related to
the engine can ignite fuel vapors
causing a fire. Once refueling is
complete, check to make sure the
filler cap and filler door are
securely closed, before starting
the engine.
• DO NOT use matches or a lighter
and DO NOT SMOKE or leave a lit
cigarette in your vehicle while at
a gas station especially during
refueling. Automotive fuel is
highly flammable and can, when
ignited, result in fire.
(Continued)(Continued)
• If a fire breaks out during refuel-
ing, leave the vicinity of the vehi-
cle, and immediately contact the
manager of the gas station and
then contact the local fire depart-
ment. Follow any safety instruc-
tions they provide.
CAUTION
• Make sure to refuel with unleaded
(or leaded for some countries)
fuel only. (Gasoline engine only)
• If the fuel filler cap requires
replacement, use only a genuine
HYUNDAI cap or the equivalent
specified for your vehicle. An
incorrect fuel filler cap can result
in a serious malfunction of the
fuel system or emission control
system.

• Do not spill fuel on the exterior
surfaces of the vehicle. Any type
of fuel spilled on painted surfaces
may damage the paint.
• After refueling, make sure the fuel
cap is installed securely to pre-
vent fuel spillage in the event of
an accident.

WARNING
• Never adjust the angle and height
of the steering wheel while driv-
ing. You may lose steering con-
trol and cause severe personal
injury, death or accidents.
• After adjusting, push the steering
wheel both up and down to be
certain it is locked in position.

Electric power steering
(if equipped)
Power steering uses the motor to assist
you in 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.
The motor driven power steering is con-
trolled by the power steering control unit
which senses the steering wheel torque
and vehicle speed to command the
motor.
The steering wheel becomes heavier as
the vehicle’s speed increases and
becomes lighter as the vehicle’s speed
decreases for better control of the steer-
ing wheel.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power steer-
ing checked by an authorized HYUNDAI
dealer.
✽NOTICE
The following symptoms may occur dur-
ing normal vehicle operation:
• The EPS warning light does not illumi-
nate.
• The steering effort is high immediately
after turning the ignition switch on.
This happens as the system performs
the EPS system diagnostics. When the
diagnostics is completed, the steering
wheel will return to its normal condi-
tion.
• A click noise may be heard from the
EPS relay after the ignition switch is
turned to the ON or LOCK position.
• Motor noise may be heard when the
vehicle is at a stop or at a low driving
speed.
• The steering effort can suddenly
increase, if the operation of the EPS
system is stopped to prevent serious
accidents when it detects malfunction
of the EPS system by self-diagnosis.
• The steering effort increases if the
steering wheel is rotated continuously
when the vehicle is not in motion.
However, after a few minutes, it will
return to its normal conditions.
D130300AEN
Tilt steering (if equipped)Tilt steering allows you to adjust the
steering wheel before you drive. You can
also raise it to give your legs more room
when you exit and enter the vehicle.
The steering wheel should be positioned
so that it is comfortable for you to drive,
while permitting you to see the instru-
ment panel warning lights and gauges.

Parking brake & brake
fluid warning
This light illuminates if the ignition switch
is turned ON and goes off in approxi-
mately 3 seconds if the parking brake is
not applied.
Parking brake warning
This warning light is illuminated when the
parking brake is applied with the ignition
switch in the START or ON position. The
warning light should go off when the
parking brake is released.
Low brake fluid level warning
If the warning light remains on, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains on:
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. Then check all brake
components for fluid leaks.
3. Do not drive the vehicle if leaks are
found, the warning light remains on or
the brakes do not operate properly.
Have it towed to any authorized
HYUNDAI dealer for brake system
inspection and necessary repairs.Your vehicle is equipped with dual-diago-
nal 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. 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.
To check bulb operation, check whether
the parking brake and brake fluid warn-
ing light illuminates when the ignition
switch is in the ON position.
CAUTION
If the oil pressure warning light
stays on while the engine is run-
ning, serious engine damage may
result. The oil pressure warning
light comes on whenever there is
insufficient oil pressure. In normal
operation, it should come on when
the ignition switch is turned on,
then goes off when the engine
starts. If the oil pressure warning
light stays on while the engine is
running, there is a serious malfunc-
tion.
If this happens, stop the vehicle as
soon as it is safe to do so, turn off
the engine and check the oil level. If
the oil level is low, fill the engine oil
to the proper level and start the
engine again. If the light stays on
with the engine running, turn the
engine off immediately. In any
instance where the oil light stays on
when the engine is running, the
engine should be checked by an
authorized HYUNDAI dealer before
the vehicle is driven again.
WARNING
Driving the vehicle with a warning
light on is dangerous. If the brake
warning light remains on, have the
brakes checked and repaired imme-
diately by an authorized HYUNDAI
dealer.
