Introduction
For customers who do not use TOP
Tier Detergent Gasoline regularly,
and have problems starting or the
engine does not run smoothly, deter-
gent-based fuel additives that you
can purchase 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 7,500 miles or 12
months is recommended.
Additives are available from your
authorized HYUNDAI dealer along
with information 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
registration and insurance.
Determine that acceptable fuel is
available. This vehicle should not be modi-
fied. Modification of your vehicle
could affect its performance, safety
or durability and may even violate
governmental safety and emis-
sions regulations.
In addition, damage or perform-
ance problems resulting from any
modification may not be covered
under warranty.
If you use unauthorized electronic
devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.By following a few simple precautions
for the first 600 miles (1,000 km) you
may add to the performance, econo-
my and life of your vehicle.
Do not race the engine.
While driving, keep your engine
speed (rpm, or revolutions per
minute) between 2,000 rpm and
4,000 rpm.
Do not maintain a single speed for
long periods of time, either fast or
slow. Varying engine speed is need-
ed to properly break-in the engine.
Avoid hard stops, except in emer-
gencies, to allow the brakes to seat
properly.

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
the reservoir is low.
When the regenerative brake does
not operate.
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). After adding
brake fluid, check all brake com-
ponents 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.
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.Parking Brake & Brake Fluid
Warning Light
Driving the vehicle with a warn-
ing light ON is dangerous. If the
Parking Brake & Brake Fluid
Warning Light illuminates with
the parking brake released, it
indicates that the brake fluid
level is low.
In this case, have the vehicle
inspected by an authorized
HYUNDAI dealer.WARNING

Driving your vehicle
Always come to a complete stop
before shifting into D (Drive) or
R (Reverse).
Do not put the shift lever in N
(Neutral) while driving.
To avoid damage to your trans-
mission, do not try to accelerate
in R (Reverse) or any forward
gear position with the brakes
applied.
When stopped on a slope, do
not hold the vehicle with accel-
erator pedal. Use the brake
pedal or the parking brake.
LCD display for transmission
temperature and warning
message
Steep Grade
This warning message is displayed
when vehicle is driven slowly on a
grade and the vehicle detects that
the brake pedal is not applied.
Driving up hills or on steep grades:
To hold the vehicle on an incline
use the foot brake or the parking
brake.
When in stop-and-go traffic on an
incline, allow a gap to form ahead
of you before moving the vehicle
forward. Then hold the vehicle on
the incline with the foot brake. If the vehicle is held or creeping
forward on an incline by applying
the accelerator pedal, the clutch
and transmission may overheat
which can result in damage. At this
time, a warning message will
appear on the LCD display.
If the LCD display warning is
active, the foot brake must be
applied.
Ignoring the warnings can lead to
damage to the transmission.
To hold the vehicle on a hill use
the foot brake or the parking
brake. If the vehicle is held by
applying the accelerator pedal on
a hill, the clutch and transmission
will be overheated resulting in
damage.
NOTICE

Transmission High Temperature
Under certain conditions, such as
repeated stop-and-go launches on
steep grades, sudden take off or
acceleration, or other harsh driving
conditions, the transmission clutch
temperatures will increase exces-
sively.
When the clutch temperatures are
too high, the "Transmission temp is
high! Stop safely" warning mes-
sage will appear on the LCD dis-
play, a chime will sound, and the
transmission shifting may not be
smooth. If this occurs, pull over to a safe
location, stop the vehicle with the
engine running, apply the brakes
and shift the vehicle to P (Park),
and allow the transmission to cool.
If you ignore this warning, the driv-
ing condition may become worse.
You may experience abrupt shifts,
frequent shifts, or jerkiness.
When the message "Trans cooled.
Resume driving." appears you can
continue to drive your vehicle.
When possible, drive the vehicle
smoothly.
Transmission Overheated
If the vehicle continues to be driv-
en and the clutch temperatures
reach the maximum temperature
limit, the "Transmission Hot! Park
with engine on" warning will be dis-
played. When this occurs the clutch
is disabled until the clutch cools to
normal temperatures.
