of the vehicle when driving uphill or
accelerating. The more electric ener-
gy is used, the higher the gauge level.

It shows the energy consumption
rate during normal driving condition.
It shows the charging status of the
battery when it is being charged by
the regenerative brakes (decelerat-
ing or driving on a downhill road).
The more electric energy is charged,
the lower the gauge level.

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 vehicle turned off, check the brake fluid level immediately
and add fluid as required (For more
information, refer to "Brake
Fluid" in chapter 7) . After adding
brake fluid, check all brake compo-
nents for fluid leaks. If a brake fluid
leak is found, or if the warning light
remains on, or if the brakes do not
operate properly, do not drive the
vehicle. Have the 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 is
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.

Good Driving Practices
Never shift to P (Park) or N(Neutral) to any other position with
the accelerator pedal depressed.
Never shift to P (Park) when the vehicle is in motion.
Be sure the vehicle is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive).
Do not shift to N (Neutral) when driving. Doing so may result in an
accident.
Do not drive with your foot resting on the brake pedal. Even light, but
consistent pedal pressure can
result in the brakes overheating,
brake wear and possibly even
brake failure.
Always apply the parking brake when leaving the vehicle. Do not
depend on placing the gear in P
(Park) to keep the vehicle from
moving. Exercise extreme caution when
driving on a slippery surface. Be
especially careful when braking,
accelerating or shifting gears. On a
slippery surface, an abrupt change
in vehicle speed can cause the
drive wheels to lose traction and
may cause loss of vehicle control
resulting in an accident
Optimum vehicle performance and economy is obtained by smoothly
depressing and releasing the
accelerator.
To reduce the risk of SERIOUS
INJURY or DEATH:
ALWAYS wear your seat belt.
In a collision, an unbelted
occupant is significantly more
likely to be seriously injured
or killed than a properly belt-
ed occupant.
Avoid high speeds when cor-
nering or turning. (Continued)
WARNING
(Continued)
Do not make quick steering
wheel movements, such as
sharp lane changes or fast,
sharp turns.
The risk of rollover is greatly
increased if you lose control
of your vehicle at highway
speeds.
Loss of control often occurs if
two or more wheels drop off
the roadway and the driver
over steers to reenter the
roadway.
In the event your vehicle
leaves the roadway, do not
steer sharply. Instead, slow
down before pulling back into
the travel lanes.
HYUNDAI recommends you
follow all posted speed limits.

Power Brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the vehicle is not in the ready
( ) mode or the vehicle is turned
off while driving, the power assist for
the brakes will not work. You can still
stop your vehicle by applying greater
force to the brake pedal than typical.
The stopping distance, however, will
be longer than with power brakes.
When the vehicle is not in the ready
( ) mode, the reserve brake
power is partially depleted each time
the brake pedal is applied. Do not
pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces.

Take the following precautions:
Do not drive with your foot
resting on the brake pedal.
This will create abnormal high
brake temperatures, exces-
sive brake lining and pad
wear, and increased stopping
distances.
When descending down a
long or steep hill, use the pad-
dle shifter (left side lever) to
increase regenerative braking
control in order to control
your speed without using the
brake pedal excessively.
Applying the brakes continu-
ously will cause the brakes to
overheat and could result in a
temporary loss of braking per-
formance.
(Continued)
(Continued)
Wet brakes may impair the
vehicle's ability to safely slow
down; the vehicle may also
pull to one side when the
brakes are applied. Applying
the brakes lightly will indicate
whether they have been
affected in this way. Always
test your brakes in this fash-
ion after driving through deep
water. To dry the brakes, light-
ly tap the brake pedal to heat
up the brakes while maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at high
speeds until the brakes func-
tion correctly.
WARNING

5-18
Driving your vehicle
Do not continue depressing the brake pedal if the " "indica-
tor is OFF. The battery may be
discharged.
Noise and vibration generated during braking is normal.
Under normal operation, electric brake pump noise and motor
vibration may occur temporarily
in below cases.
- When the pedal is depressedsuddenly.
- When the pedal is repeatedly depressed in short intervals.
- When the ABS function is acti- vated while braking.
Disc Brake Wear Indicator
When your brake pads are worn and
new pads are required, you will hear
a high pitched warning sound from
your front or rear brakes. You may
hear this sound come and go or it
may occur whenever you depress
the brake pedal.
Note that some driving conditions or
climates may cause a brake squeal
when you first apply (or lightly apply)
the brakes. This is normal and does
not indicate a problem with your
brakes.
To avoid costly brake repairs, do
not continue to drive with worn
brake pads.
Information
Always replace brake pads as com-
plete front or rear axle sets.
Electronic Parking Brake
(EPB)
Applying the parking brake
To apply the EPB (Electronic
Parking Brake):
1. Depress the brake pedal.
2. Pull the EPB switch upwards.
Make sure the Parking Brake
Warning Light comes on.
With the AUTO HOLD feature
enabled, the EPB is automatically
applied when the vehicle is shut off.
