Electric Power Steering (EPS)
The system assists you with steering
the vehicle. If the engine is turned off
or if the power steering system
becomes inoperative, you may still
steer the vehicle, but it will require
increased steering effort.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the system
checked by an authorized HYUNDAI
dealer.
Information
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 completed,
the steering wheel will return to its
normal condition.
• A click noise may be heard from the EPS relay after the ignition switch is
in the ON or OFF position.
• Motor noise may be heard when the vehicle is at a stop or at a low driv-
ing speed.
• When you operate the steering wheel in low temperature, abnormal
noise may occur. If temperature
rises, the noise will disappear. This
is a normal condition.
i
If the Electric Power Steering
System does not operate nor-
mally, the warning light ( ) will
illuminate on the instrument
cluster. You may steer the vehi-
cle, but it will require increased
steering efforts. Take your vehi-
cle to an authorized HYUNDAI
dealer and have the system
checked as soon as possible.

(Continued)
Do not get back into a vehicle
once you have begun refuel-
ing. You can generate a build-
up of static electricity by
touching, rubbing or sliding
against any item or fabric
capable of producing static
electricity. Static electricity
discharge can ignite fuel
vapors causing a fire. If you
must re-enter the vehicle, you
should once again eliminate
potentially dangerous static
electricity discharge by touch-
ing a metal part of the vehicle,
away from the fuel filler neck,
nozzle or other gasoline
source, with your bare hand.
When using an approved
portable fuel container, be
sure to place the container on
the ground prior to refueling.
Static electricity discharge
from the container can ignite
fuel vapors causing a fire.(Continued)
(Continued)Once refueling has begun,
contact between your bare
hand and the vehicle should
be maintained until the filling
is complete.
Use only approved portable
plastic fuel containers designed
to carry and store gasoline.
When refueling, always move
the shift lever to the P (Park)
position, set the parking
brake, and place the ignition
switch to the LOCK/OFF posi-
tion. Sparks produced by
electrical components related
to the engine can ignite fuel
vapors causing a fire.
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.
Do not over-fill or top-off your
vehicle tank, which can cause
gasoline spillage. (Continued)
(Continued)
If a fire breaks out during refu-
eling, leave the vicinity of the
vehicle, and immediately con-
tact the manager of the gas
station and then contact the
local fire department. Follow
any safety instructions they
provide.
If pressurized fuel sprays out,
it can cover your clothes or
skin and thus subject you to
the risk of fire and burns.
Always remove the fuel cap
carefully and slowly. If the cap
is venting fuel or if you hear a
hissing sound, wait until the
condition stops before com-
pletely removing the cap.
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.

If the brake fluid level in the reser-
voir 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 7) . Then check all
brake components for fluid leaks. If
any leak on the brake system is still
found, the warning light remains on,
or the brakes do not operate prop-
erly, do not drive the vehicle. In this
case, have your 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 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.
