Do not operate the engine within
the tachometer's RED ZONE. This
may cause severe engine damage.
Engine Coolant TemperatureGauge
This gauge indicates the tempera-
ture of the engine coolant when the
ignition switch or Engine Start/Stop
button is ON. If the gauge pointer moves
beyond the normal range area
toward the "H" position, it indi-
cates overheating that may dam-
age the engine.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to "If the Engine
Overheats" in chapter 6.

Never remove the radiator cap
when the engine is hot. The
engine coolant is under pressure
and could severely burn. Wait
until the engine is cool before
adding coolant to the reservoir.

When Active ECO is activated:
The acceleration response may beslightly reduced as the accelerator
pedal is depressed moderately.
The air conditioner performance may be limited.
The shift pattern of the automatic transmission may change.
The engine noise may get louder.
The above situations are normal
conditions when the Active ECO sys-
tem is activated to improve fuel effi-
ciency. Limitation of Active ECO opera-
tion:
If the following conditions occur while
Active ECO is operating, the system
operation is limited even though
there is no change in the ECO indi-
cator.
When the coolant temperature is
low:
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
engine torque is restricted.
When using the automatic trans- mission Sports mode:
The system will be limited accord-
ing to the shift location.SPORT mode
SPORT mode focuses ondynamic driving by auto-
matically controlling the
steering wheel, engine
and transmission system.
When the DRIVE MODE switch is pressed and the SPORT mode is
selected, the SPORT indicator
(yellow) will illuminate.
When the SPORT mode is activat- ed, and the engine is turned off
and on it will change to NORMAL
mode. To turn on the SPORT
mode, press the DRIVE MODE
switch again.
If the system is activated: - After accelerating and releasingthe accelerator pedal, the gear
and engine speed RPM may not
drop as soon as in NORMAL
mode.
- Up-shifting is delayed.
Information
In SPORT mode, the fuel efficiency
may decrease.

- When using tire chains:
Wrong size chains or improperlyinstalled chains can damage
your vehicle's brake lines, sus-
pension, body and wheels.
Use SAE “S” class or wire chains.
If you hear noise caused by chains contacting the body,
retighten the chain to prevent
contact with the vehicle body.
To prevent body damage, retighten the chains after driving
0.3~0.6 miles (0.5~1.0 km).
Do not use tire chains on vehi- cles equipped with aluminum
wheels. If unavoidable, use a
wire type chain.
Use wire chains less than 0.47 inch (12 mm) wide to prevent
damage to the chain’s connec-
tion.
Winter Precautions
Use high quality ethylene glycolcoolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Change to "winter weight" oil ifnecessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized HYUNDAI dealer or a
service station.
