•When refuelling, always move
the shift lever to the P (Park)
position (for automatic
transaxle) or first gear or R
(Reverse, for manual
transaxle), 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
vapours causing a fire.
•When using an approved
portable fuel container, be sure
to place the container on the
ground prior to refuelling. Static
electricity discharge from the
container can ignite fuel
vapours causing a fire. Once
refuelling has begun, contact
between your bare hand and
the vehicle should be main-
tained until the filling is com-
plete.

•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.
(Continued)
•Use only approved portable
plastic fuel containers designed
to carry and store petrol.
•Do not use matches or a
lighter and do not smoke or
leave a lit cigarette in your
vehicle whilst at a gas station,
especially during refuelling.
•Do not over-fill or top-off your
vehicle tank, which can cause
petrol spillage.
•If a fire breaks out during refu-
elling, 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.

Parking Brake & Brake
Fluid Warning Light
This warning light illuminates:
• Once you set the ignition switch or
the 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 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
details, refer to “Brake Fluid” in
chapter 7). Then check all brake
components for fluid leaks. If any
leak in 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
authorised 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 whilst 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.
