Introduction
For customers who do not use TOP
Tier Detergent Gasoline regularly,
and have problems starting or the
engine does not run smoothly, addi-
tives that you can buy separately
may be added to the gasoline. If TOP
TIER Detergent Gasoline is not avail-
able, 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. 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, 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.

Parking Brake & BrakeFluid Warning Light
This warning light illuminates:
When the Engine Start/Stop button
is in the ON position
- It illuminates for approximately 3seconds and then goes off.
- 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 illuminateswith the parking brake released, it
indicates the brake fluid level in
reservoir is low.
When the regenerative brake does not operate.
When only one of the dual system is working, the stopping distance
will be increased
If the brake fluid level in the reser-
voir is low:
1. Drive carefully to the nearest safe location and stop your vehicle.
2. Stop the vehicle, immediately check the brake fluid level and add
fluid, if necessary (For more infor-
mation, refer to "Brake Fluid" in
the chapter 7). Then check all
brake components for fluid leaks.

is still detected, when the warning
light remains ON, or when the
brakes do not properly operate, do
not drive the vehicle.
Have the vehicle towed to an
authorized 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 systems fails.
With only one of the dual systems
working, longer pedal travel and
greater pedal pressure should be
required. Also, the vehicle will not stop in a
short distance only with one of the
brake systems.
If the brakes fail, while driving, shift
to a lower gear for additional engine
braking and stop the vehicle as soon
as it is safe to do so.
(red color)
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.

Driving your vehicle
R (Reverse)
Use this position to drive the vehicle
backward.
Always come to a complete stop
before shifting into or out of R
(Reverse); you may damage the
transmission if you shift into R
(Reverse) while the vehicle is in
motion.
N (Neutral)
The wheels and transmission 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 driving position.
The transmission will automatically
shift through a 6-gear sequence, pro-
viding the best fuel economy and
power.
For extra power when passing anoth-
er vehicle or driving uphill, depress
the accelerator fully. The transmis-
sion will automatically downshift to
the next lower gear (or gears, as
appropriate).
The DRIVE MODE switch, located on
the shift lever console, allows the driv-
er to switch from NORMAL mode to
SPORT or ECO mode.
For more information, refer to
"Drive Mode Integrated Control
System" later in this chapter.
NOTICE
Do not drive with the shift lever
in N (Neutral).
The engine brake will not work
and lead to an accident.
WARNING

Parking
Always come to a complete stop and
continue to depress the brake pedal.
Move the shift lever into the P (Park)
position, apply the parking brake,
and place the Engine Start/Stop but-
ton in the OFF position. Take the Key
with you when exiting the vehicle.
Good driving practices
Never move the shift lever from P(Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.
Never move the shift lever into 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 move the shift lever to N (Neutral) when driving. Doing so
may result in an accident because
of a loss of engine braking and the
transmission could be damaged.
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 transmis-
sion 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.
When you stay in the vehicle
with the engine running, be
careful not to depress the accel-
erator pedal for a long period of
time. The engine or exhaust
system may overheat and start
a fire.
The exhaust gas and the
exhaust system are very hot.
Keep away from the exhaust
system components.
Do not stop or park over flam-
mable materials, such as dry
grass, paper or leaves. They
may ignite and cause a fire.

Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the hybrid system is not on or 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 dis-
tance, however, will be longer than
with power brakes.
When the hybrid system is not on,
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.Do not depress the brake pedal
continuously without the " "
indicator ON. The battery may be
discharged.

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, move the
gear shift lever to Manual
Shift Mode and manually
downshift to a lower gear in
order to control your speed
without using the brake pedal
excessively. Applying the
brakes continuously will
cause the brakes to overheat
and could result in a tempo-
rary loss of braking perform-
ance.
(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.
