Emergency fuel filler lid release
If the fuel filler lid does not open
using the remote fuel filler lid
release, you can open it manually by
pulling the handle outward slightly.
(Continued)
• When refueling, always shut
the engine off. Sparks pro-
duced by electrical compo-
nents related to the engine
can ignite fuel vapors causing
a fire. Once refueling is com-
plete, check to make sure the
filler cap and filler door are
securely closed, before start-
ing 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.
• 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.CAUTION
• Make sure to refuel your vehi-
cle according to the "Fuel
requirements" suggested in
section 1.
• If the fuel filler cap requires
replacement, use only a gen-
uine 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 exteri-
or 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 prevent fuel spillage in the
event of an accident.
CAUTION
Do not pull the handle exces-
sively, otherwise the luggage
area trim or release handle may
be damaged.

A driver position memory system is
provided to store and recall the driv-
er seat, outside rearview mirrors,
steering wheel position and HUD
(Head-Up Display) height with a sim-
ple button operation. By saving the
desired positions into the system
memory, different drivers can reposi-
tion the driver seat, outside rearview
mirrors, steering wheel and HUD
(Head-Up Display) height based
upon their driving preference. If the
battery is disconnected, the position
memory will be lost and the driving
positions should be restored in the
system.
✽NOTICE
If the memory system does not oper-
ate normally, have the driver posi-
tion memory system checked by an
authorized HYUNDAI dealer.

STEERING WHEEL
Power steering
Power steering uses energy from the
engine 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.
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.
Electronic Hydraulic Power
Steering (EHPS)
EHPS uses an electromotor to assist
you in steering the vehicle. It senses
the vehicle speed and road condition.
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.
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
If the power steering drive belt
breaks or if the power steering
pump malfunctions, the steering
effort will greatly increase.
✽NOTICE
If the vehicle is parked for extended
periods outside in cold weather
(below -10°C/14°F), the power steer-
ing may require increased effort
when the engine is first started. This
is caused by increased fluid viscosity
due to the cold weather and does not
indicate a malfunction.
When this happens, increase the
engine RPM by depressing accelera-
tor until the RPM reaches 1,500 rpm
then release or let the engine idle for
two or three minutes to warm up the
fluid.
CAUTION
Never hold the steering wheel
against a stop (extreme right or
left turn) for more than 5 sec-
onds with the engine running.
Holding the steering wheel for
more than 5 seconds in either
position may cause damage to
the power steering pump.

Parking Brake & Brake
Fluid Warning Light
This warning light illuminates:
• Once you set the ignition switch or
Engine Start/Stop Button to 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
reservoir 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 still
found, the warning light remains
on, or the brakes do not operate
properly, do not drive the vehicle.
In this case, we recommend that
you have the 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.
