Gauges and Meters
Speedometer/ECO guide
The speedometer indicates the
speed of the vehicle and is calibrated
in miles per hour (mph) and/or kilo-
meters per hour (km/h).The speedometer is displayed differ-
ently according to the selected drive
mode in the Drive Mode Integrated
Control System.
For more information, refer to
“Drive Mode Integrated Control
System” in chapter 5.
Power/Charge gauge
The Power/Charge gauge shows the
energy consumption rate of the vehi-
cle and the charge/discharge status
of the regenerative brakes.

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

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.State of Charge (SOC) gauge for
high voltage battery
The SOC gauge shows the charging
status of the high voltage battery.
"L (Low)" position on the indicator
indicates that there is not enough
energy in the high voltage battery. "H
(High)" position indicates that the
driving battery is fully charged.
When driving on highways or motor-
ways, make sure to check in advance
if the driving battery is charged
enough.When there are 4~5 gauge bars
(near the "L (Low)" area) on the SOC
gauge, the warning lamp turns ON to
alert you of the battery level.
When the warning lamp turns ON,
the vehicle can drive an additional
18~25 miles (30~40 km) depending
on the driving speed, heater/air con-
ditioner, weather, driving style, and
other factors. Charging is required.

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.
Alway apply the parking brake
when parked on a sloped driveway
or hill 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. Also,
avoid increasing the regenerative
braking level suddenly. On a slip-
pery surface, an abrupt change in
vehicle speed can cause the drive
wheels to lose traction and may
cause loss of vehicle control result-
ing 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.

The Smart Regeneration System
may not operate temporarily due
to:
Electrical interference
Modifying the suspension
Differences of tire abrasion or
tire pressure
Installing different type of tires
NOTICE
Driving your vehicle
(Continued)
Vehicles moving in front of
you with frequent lane
changes may cause a delay in
the system's reaction or may
cause the system to react to a
vehicle actually in an adjacent
lane. Always drive cautiously
to prevent unexpected and
sudden situations from occur-
ring.
The Smart Regeneration
System may not recognize
complex driving situations so
always pay attention to driv-
ing conditions and control
your vehicle speed.
When using the Smart
Regeneration System take the
following precautions:
If an emergency stop is nec-
essary, you must apply the
brakes.
Keep a safe distance accord-
ing to road conditions and
vehicle speed. If the vehicle-
to-vehicle distance is too
close and the brakes are sud-
denly applied, a serious colli-
sion may result.
Always maintain sufficient
braking distance and deceler-
ate your vehicle by applying
the brakes if necessary.
The Smart Regeneration
System cannot recognize a
stopped vehicle, pedestrians
or an oncoming vehicle.
Always look ahead cautiously
to prevent unexpected and
sudden situations from occur-
ring.

WARNING

5-26
Driving your vehicle
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.
