Introduction
Fuel Additives
HYUNDAI recommends that you use
good quality gasolines treated with deter-
gent additives such as TOP TIER
Detergent Gasoline, which help prevent
deposit formation in the engine. These
gasolines will help the engine run cleaner
and enhance performance of the Emission
Control System. For more information on
TOP TIER Detergent Gasoline, please go
to the website (www.toptiergas.com)
For customers who do not use TOP Tier
Detergent Gasoline regularly, and have
problems starting or the engine does not
run smoothly, additives that you can buy
separately may be added to the gasoline.
If TOP TIER Detergent Gasoline is not
available, one bottle of additive added to
the fuel tank at every 7,500mile or every
engine oil change is recommended.
Additives are available from your author-
ized HYUNDAI dealer along with informa-
tion on how to use them. Do not mix other
additives.
Operation in foreign countries
If you are going to drive your vehicle in
another country, be sure to:
Observe all regulations regarding reg-istration and insurance.
Determine that acceptable fuel is avail- able. No special break-in period is needed. By
following a few simple precautions for the
first 600 miles (1,000 km) you may add to
the performance, economy and life of
your vehicle.
Do not race the engine.
Avoid hard stops, except in emergen-
cies, to allow the brakes to seat prop-
erly.
Don't tow a trailer during the first 1,200 miles (2,000 km) of operation.

WARNING
Driving the vehicle with a warning
light on is dangerous. If the brake
warning light remains on, have the
brakes checked and repaired imme-
diately by an authorized HYUNDAI
dealer.
Brake system &
Parking brake & Brake fluid warning light
When the service brake system or the
regenerative brake system malfunctions,
the brake warning light is turned on and
'check brake' is displayed on the LCD.
Have the system checked by an author-
ized HYUNDAI dealer as soon as possi-
ble.
Parking brake warning
This light illuminated when the parking
brake is applied with engine start/stop
button in the START or ON position. The
warning light should go off when the
parking brake is released. Low brake fluid level warning
If the warning light remains on, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains on:
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. Then check all brake
components for fluid leaks.
3. Do not drive the vehicle if leaks are found, the warning light remains on or
the brakes do not operate properly.
Have the vehicle towed to any author-
ized HYUNDAI dealer for a brake sys-
tem inspection and necessary repairs.
Your vehicle is equipped with a dual-
diagonal braking system. This means you
still have braking on two wheels even if
one of the brake circuits is damaged or
malfunctions. With only one of the circuits
working, more than normal pedal travel
and greater pedal pressure are required
to stop the car. Also, the car will not stop
in as short a distance with only a portion
of the brake system working. If the
brakes fail while you are driving, shift to a
lower gear for additional engine braking
and stop the car as soon as it is safe to
do so. To check bulb operation, check whether
the parking brake and brake fluid warning
light illuminates when the engine
start/stop button is in the ON position.
CAUTION
When the service brake system and
the regenerative brake system mal-functions, the brake warning light is turned on and 'check brake' is dis-played on the LCD, and also the warn- ing chime will sound. If this occursyou can stop your vehicle by apply-ing greater force to the brake pedal than normal and the stopping dis-tance will be longer. Have the system checked by an authorized HYUNDAIdealer as soon as possible.

Features of your vehicle
Low tire pressure telltale
The low tire pressure telltale illuminates
when one or more of your tires is signifi-
cantly underinflated.
The low tire pressure telltale will illumi-
nate after it blinks for approximately one
minute when there is a problem with the
Tire Pressure Monitoring System.
If this occurs, have the system checked
by an authorized HYUNDAI dealer as
soon as possible.
For details, refer to the TPMS on Chapter 6.
Automatic Transaxle shift
indicator
The indicator displays which automatic
transaxle shift position is selected.
✽ ✽ NOTICE
When the system is not working proper-
ly, the gear is not displayed. Have the
system checked by an authorized
HYUNDAI dealer.
WARNING - Low tire pres-
sure
Significantly low tire pressure
makes the vehicle unstable and can
contribute to loss of vehicle control
and increased braking distances.
Continued driving on tires with low
pressure will cause the tires to
overheat and fail.
WARNING - Safe stopping
The TPMS cannot alert you to
severe and sudden tire damage
caused by external factors.
If you feel any vehicle instability, immediately take your foot off the
accelerator, apply the brakes
gradually and with light force,
and slowly move to a safe posi-
tion off the road.

For smooth operation, depress the brake
pedal when shifting from N (Neutral) to aforward or reverse gear. Transaxle ranges
The indicator in the instrument cluster
displays the shift lever position when the
engine start/stop button is in the ON
position.
P (Park)
Always come to a complete stop before
shifting into P (Park). This position locks
the transaxle and prevents the drive
wheels from rotating.
WARNING- Automatic
transaxle
Always check the surrounding
areas near your vehicle for peo-
ple, especially children, before
shifting a car into D (Drive) or R
(Reverse).
Before leaving the driver’s seat, always make sure the shift lever
is in the P (Park) position; then
set the parking brake fully and
shut the HEV system off.
Unexpected and sudden vehicle
movement can occur if these pre-
cautions are not followed in the
order identified.
CAUTION
To avoid damage to your transaxle, do not accelerate theengine in R (Reverse) or any for-ward gear position with thebrakes on.
When stopped on an incline, do not hold the vehicle stationarywith engine power. Use the serv-ice brake or the parking brake.
WARNING
Shifting into P (Park) while the vehi- cle is in motion will cause the drive
wheels to lock which will cause you
to lose control of the vehicle.
Do not use the P (Park) position in place of the parking brake.
Always make sure the shift lever
is latched in the P (Park) position
and set the parking brake fully.
Never leave a child unattended in a vehicle.
CAUTION
The transaxle may be damaged ifyou shift into P (Park) while thevehicle is in motion.

Driving your vehicle
R (Reverse)
Use this position to drive the vehicle
backward.N (Neutral)
The wheels and transaxle are not
engaged. The vehicle will roll freely even
on the slightest incline unless the parking
brake or service brakes are applied.
D (Drive)
This is the normal forward driving posi-
tion. The transaxle will automatically shift
through a 6-gear sequence, providing the
best fuel economy and power.
For extra power when passing another
vehicle or climbing grades, depress the
accelerator, at which time the transaxle
will automatically downshift to a lower
gear.
✽ ✽
NOTICE
Always come to a complete stop before
shifting into D (Drive).
Sports mode
Whether the vehicle is stationary or in
motion, sports mode is selected by push-
ing the shift lever from the D (Drive) posi-
tion into the manual gate. To return to D
(Drive) range operation, push the shift
lever back into the D (Drive) position.
In sports mode, moving the shift lever
backwards and forwards will allow you to
make gearshifts rapidly.
Up (+) : Push the lever forward once to
shift up one gear.
Down (-) : Pull the lever backwards once to shift down one gear.
CAUTION
Always come to a complete stopbefore shifting into or out of R(Reverse); you may damage thetransaxle if you shift into R(Reverse) while the vehicle is in motion, except as explained in“Rocking the vehicle” in this sec-tion.

Good driving practices
Never move the gear shift lever from P(Park) or N (Neutral) to any other posi-
tion with the accelerator pedal
depressed.
Never move the gear shift lever into P (Park) when the vehicle is in motion.
Be sure the car is completely stopped before you attempt to shift into R
(Reverse) or D (Drive).
Never take the car out of gear and coast down a hill. This may be
extremely hazardous. Always leave the
car in gear when moving.
Do not "ride" the brakes. This can cause them to overheat and malfunc-
tion. Instead, when you are driving
down a long hill, shift into sports mode,
slown down and shift to a lower gear.
When you do this, engine braking will
help slow the car.
Always use the parking brake when parked. Do not depend on placing the
transaxle in P (Park) to keep the car
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 the vehicle to go out of control.
Optimum vehicle performance and economy is obtained by smoothly
depressing and releasing the accelera-
tor pedal.WARNING
Always buckle-up! In a collision,an unbelted occupant is signifi-
cantly more likely to be seriously
injured or killed than a properly
belted occupant.
Avoid high speeds when corner- ing or turning.
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.
Never exceed posted speed lim- its.

Moving up a steep grade from a stand-
ing start
To move up a steep grade from a stand-
ing start, depress the brake pedal, shift
the shift lever to D (Drive). Depress the
accelerator gradually while releasing the
service brakes.
Power brakes
Your vehicle's brake system is power-
assisted by the electric hydraulic pump.
In the event the brakes lose power
because of a brake control system mal-
function, unstable power supply or some
other reason, you can still stop your vehi-
cle by applying greater force to the brake
pedal than you normally would. The stop-
ping distance, however will be longer. For
your safety, please have the system
checked as soon as possible.WARNING
If your vehicle becomes stuck in
snow, mud, sand, etc., then you
may attempt to rock the vehicle free
by moving it forward and backward.
Do not attempt this procedure if
people or objects are anywhere
near the vehicle. During the rocking
operation the vehicle may suddenly
move forward or backward as it
becomes unstuck, causing injury
or damage to nearby people or
objects.
BRAKE SYSTEM
WARNING- Brakes
Do not drive with your foot rest- ing on the brake pedal. This will
create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increased
stopping distances.
When descending a long or steep hill, move the shift lever to sports
mode, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brake
application will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.

Driving your vehicle
In the event of brake failure
If service brakes fail to operate while the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
✽ ✽NOTICE
1) When you apply the brake repeatedly,
you may hear the sound the electric
hydraulic pump or motor operating.
This is a normal condition.
2) The following types of pedal applica- tions may result in the brake pedal
feeling different, however it is normal
condition.
- When you apply the pedal quickly
- When you apply the pedal continu-ously and repeatedly
- While braking, when the ABS oper- ated
(Continued)
Wet brakes may impair the vehi-
cle’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 fashion after
driving through deep water. To
dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
Always confirm the position of the brake and accelerator pedal
before driving. If you don't check
the position of the accelerator
and brake pedal before driving,
you may depress the accelerator
instead of the brake pedal. It may
cause a serious accident.
Do not turn off the Hybrid system while going down a hill. The brake
booster may not work sufficiently
and the braking distance may be
longer.
(Continued)(Continued)
If the brake pedal does not returnto its normal position when
released, there may be a malfunc-
tion in the brake system. Take
your vehicle to an authorized
HYUNDAI dealer and have the
system checked.
To avoid applying the brakes do not get too close to the vehicle in
front of you and try to avoid
going down steep roads or sharp
corning if the power assisted
brakes are not functioning nor-
mally. The vehicle will stop but
the braking distance may be
longer.
WARNING- Parking brake
Applying the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you must
use the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.
CAUTION
If the driver’s door is not firmlyclosed, the auxiliary battery may bedischarged because the brake con-troller remains in standby opera-tion. To prevent the battery frombeing discharged, ensure the door is fully closed.
