ESC OFF usage
When driving
The ESC OFF mode should only be
used briefly to help free the vehicle if
stuck in snow or mud by temporarily
stopping operation of the ESC to
maintain wheel torque.
To turn ESC off while driving, press
the ESC OFF button while driving on
a flat road surface.
✽ ✽
NOTICE
Turning the ESC OFF does not
affect ABS or standard brake sys-
tem operation.
CAUTION
To prevent damage to the
transaxle:
Do not allow wheel(s) of one axle to spin excessively whilethe ESC, ABS, and brakewarning lights are displayed.The repairs would not be cov-ered by the vehicle warranty.Reduce engine power and donot spin the wheel(s) exces-sively while these lights aredisplayed.
When operating the vehicle on a dynamometer, ensure theESC is turned off (ESC OFFlight illuminated).
WARNING
When the ESC is blinking, this
indicates the ESC is active:
Drive slowly and NEVER
attempt to accelerate. NEVER
press the ESC OFF button while
the ESC indicator light is blink-
ing or you may lose control of
the vehicle resulting in an acci-
dent.
CAUTION
Driving with varying tire orwheel sizes may cause the ESCsystem to malfunction. Whenreplacing tires, make sure theyare the same size as your origi-nal tires for this vehicle.

✽
✽NOTICE
• The HAC does not operate when
the transaxle shift lever is in the P
(Park) or N (Neutral) position.
• The HAC activates even though the ESC is off but it does not acti-
vate when the ESC has malfunc-
tioned.
Good braking practices
After being parked, check to be
sure the parking brake is not
engaged and that the parking
brake indicator light is out before
driving away. Driving through water may get the
brakes wet. They can also get wet
when the vehicle is washed. Wet
brakes can be dangerous! Your
vehicle will not stop as quickly if the
brakes are wet. Wet brakes may
cause the vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns
to normal, taking care to keep the
vehicle under control at all times. If
the braking action does not return to
normal, stop as soon as it is safe to
do so and call an authorized
HYUNDAI dealer for assistance.
Don't coast down hills with the vehicle out of gear. This is extreme-
ly hazardous. Keep the vehicle in
gear at all times, use the brakes to
slow down, then shift to a lower
gear so that engine braking will
help you maintain a safe speed.
Don't "ride" the brake pedal. Resting your foot on the brake
pedal while driving can be danger-
ous because it can result in the
brakes overheating and losing their
effectiveness. It also increases the
wear of the brake components.
WARNING
Whenever you leave or parkyour vehicle, always set the
parking brake as far as possi-
ble and fully engage the vehi-
cle's transaxle into the P (Park)
position. If the parking brake is
not fully engaged, the vehicle
may move inadvertently and
injure yourself and others.
All vehicles should always have the parking brake fully
engaged when parking to
avoid inadvertent movement
of the vehicle which can injure
occupants or pedestrians.

Active ECO operation
Active ECO helps improve fuel effi-
ciency by controlling certain engine
and transaxle system operating
parameters. Fuel efficiency depends
on the driver's driving habit and road
condition. When the Active ECO button is
pressed the ECO indicator (green)
will illuminate to show that the
Active ECO is operating.
When the Active ECO is activated, it will remain on until the Active
ECO button is pressed again.
Active ECO does not turn off when
the engine is restarted. To turn off
Active ECO, press the Active ECO
button again.
If Active ECO is turned off, the sys- tem will return to normal mode.When Active ECO is activated :
The engine noise may get louder.
The vehicle speed may slightly bereduced.
The air conditioner performance may be affected.
Limitation of Active ECO oper-
ation:
If the following conditions occur while
Active ECO is operating, the system
operation is limited even though there
is no change in the ECO indicator.
When the coolant temperature islow: The system will be limited until
engine performance becomes nor-
mal.
When driving up a hill: The system will be limited to gain power when
driving uphill because the engine
torque is restricted.
When using sports mode: The sys- tem will be limited according to the
shift location.
When the accelerator pedal is deeply depressed for a few sec-
onds: The system will be limited,
judging that the driver wants to
speed up.

Driving your vehicle
Your vehicle's fuel economy depends
mainly on your style of driving, where
you drive and when you drive.
Each of these factors affects how
many miles (kilometers) you can get
from a gallon (liter) of fuel. To oper-
ate your vehicle as economically as
possible, use the following driving
suggestions to help save money in
both fuel and repairs:
Drive smoothly. Accelerate at amoderate rate. Don't make "jack-
rabbit" starts or full-throttle shifts
and maintain a steady cruising
speed. Don't race between stop-
lights. Try to adjust your speed to
the traffic so you don't have to
change speeds unnecessarily.
Avoid heavy traffic whenever possi-
ble. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your
vehicle uses. Driving at a moderate
speed, especially on the highway,
is one of the most effective ways to
reduce fuel consumption. Don't "ride" the brake pedal. This
can increase fuel consumption and
also increase wear on these com-
ponents. In addition, driving with
your foot resting on the brake pedal
may cause the brakes to overheat,
which reduces their effectiveness
and may lead to more serious con-
sequences.
Take care of your tires. Keep them inflated to the recommended pres-
sure. Incorrect inflation, either too
much or too little, results in unnec-
essary tire wear. Check the tire
pressures at least once a month.
Be sure that the wheels are aligned correctly. Improper align-
ment can result from hitting curbs
or driving too fast over irregular
surfaces. Poor alignment causes
faster tire wear and may also result
in other problems as well as
greater fuel consumption. Keep your vehicle in good condi-
tion. For better fuel economy and
reduced maintenance costs, main-
tain your vehicle in accordance
with the maintenance schedule in
Section 7. If you drive your vehicle
in severe conditions, more frequent
maintenance is required (see
Section 7 for details).
Keep your vehicle clean. For maxi- mum service, your vehicle should
be kept clean and free of corrosive
materials. It is especially important
that mud, dirt, ice, etc. not be
allowed to accumulate on the
underside of the vehicle. This extra
weight can result in increased fuel
consumption and also contribute to
corrosion.
Travel lightly. Don't carry unneces- sary weight in your vehicle. Weight
reduces fuel economy.
Don't let the engine idle longer than necessary. If you are waiting
(and not in traffic), turn off your
engine and restart only when
you're ready to go.

Remember, your vehicle does not
require extended warm-up. After
the engine has started, allow the
engine to run for 10 to 20 seconds
prior to placing the vehicle in gear.
In very cold weather, however, give
your engine a slightly longer warm-
up period.
Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in too
high a gear resulting engine buck-
ing. If this happens, shift to a lower
gear. Over-revving is racing the
engine beyond its safe limit. This
can be avoided by shifting at the
recommended speeds.
Use your air conditioning sparingly. The air conditioning system is
operated by engine power so your
fuel economy is reduced when you
use it.
Open windows at high speeds can reduce fuel economy.
Fuel economy is less in crosswinds and headwinds. To help offset
some of this loss, slow down when
driving in these conditions. Keeping a vehicle in good operating
condition is important both for econ-
omy and safety. Therefore, have an
authorized HYUNDAI dealer perform
scheduled inspections and mainte-
nance.
WARNING - Engine off
during
motion
Never turn the engine off to
coast down hills or anytime the
vehicle is in motion. The power
steering and power brakes will
not function properly without the
engine running. Instead, keep
the engine on and downshift to
an appropriate gear for engine
braking effect. In addition, turn-
ing off the ignition while driving
could engage the steering wheel
lock resulting in loss of vehicle
steering which could cause
serious injury or death.
