tion, and will go out in a few seconds
after the engine is started. If it illuminates
whilst driving, or does not illuminate
when the ignition switch is turned to the
ON position, take your vehicle to your
nearest authorised HYUNDAI dealer and
have the system checked.
Generally, your vehicle will continue to be
drivable, but have the system checked by
an authorised HYUNDAI dealer promptly.

Engine coolant tempera-ture warning light (if equipped)
The warning light illuminates if the tem-
perature of the engine coolant is above125±2.5°C (257±4.5°F).
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “Overheating” in section 6.
✽✽ NOTICE
If the engine coolant temperature warn-
ing light illuminates, it indicates over-
heating that may damage the engine.
ESP (Electronic Stability Program) indicator (if equipped)
The ESP indicator will illuminate when
the ignition switch is turned ON, but
should go off after approximately 3 sec-
onds. When the ESP is on, it monitors the
driving conditions. Under normal driving
conditions, the ESP indicator will remain
off. When a slippery or low traction con-dition is encountered, the ESP will oper-
ate, and the ESP indicator will blink to
indicate the ESP is operating. But, if the ESP system malfunctions the
indicator illuminates and stays on. Take
your vehicle to an authorised HYUNDAI
dealer and have the system checked.

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 fully, at which time the
transaxle will automatically downshift to
the lower gear.
✽✽
NOTICE
Always come to a complete stop before
shifting into D (Drive).
CAUTION
The transaxle may be damaged if you shift into P (Park) whilst the
vehicle is in motion.

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
kilometers (miles) you can get from a litre
(gallon) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
Drive smoothly. Accelerate at a moder-ate rate. Don't make "kangaroo" starts or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to that of the other traffic so you
don't have to change speeds unneces-
sarily. Avoid heavy traffic whenever
possible. 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 car uses.
Driving at a moderate speed, especial-
ly on the highway, is one of the most
effective ways to reduce fuel consump-tion. Don't "ride" the brake pedal. This can
increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing on the brake pedal may cause the
brakes to overheat, which reduces
their effectiveness and may lead to
more serious consequences.
Take care of your tyres. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tyre
wear. Check the tyre pressures at leastonce a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting kerbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tyre wear and may
also result in other problems as well as
greater fuel consumption. Keep your car in good condition. For
better fuel economy and reduced
maintenance costs, maintain your carin accordance with the maintenance
schedule in section 7. If you drive your
car in severe conditions, more frequentmaintenance is required (see section 7
for details).
Keep your car clean. For maximum 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 car. This extra
weight can result in increased fuel con-
sumption and also contribute to corro-sion.
Travel lightly. Don't carry unnecessary weight in your car. 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.
ECONOMICAL OPERATION

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 plac-
ing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warm-up period.
Don't "labour" or "over-rev" the engine. Labouring is driving too slowly in toohigh a gear resulting in the engine
bucking. If this happens, shift to a lower
gear. Over-revving is racing the engine
beyond its safe limit. This can be avoid-
ed by shifting at the recommended
speeds. Use your air conditioning sparingly.
The air conditioning system is operat-
ed by engine power so your fuel econ-
omy 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 con-
dition is important both for economy and
safety. Therefore, have an authorised
HYUNDAI dealer perform scheduled
inspections and maintenance.
WARNING - Engine off dur-
ing 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 run-
ning. Instead, keep the engine on
and downshift to an appropriate
gear for engine braking effect. In
addition, turning off the ignition
whilst driving could engage the
steering wheel lock resulting in
loss of vehicle steering which
could cause serious injury ordeath.
