Air cleaner filter
We recommend that the air cleaner filter
be replaced by an authorized HYUNDAI
dealer.
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
When installing new spark plugs, be sure
that the ignition coils are clean and free
of any oil or debris. Clean and wipe off
the bottom portion of the ignition coil in
order to prevent any contamination with
the spark plug during installation.
WARNING
Do not remove spark plugs from the
vehicle when the engine is hot. You
may damage the engine and may also
risk burn injury.
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Engine coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Engine coolant/water-cooled
intercooler coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Automatic transmission fluid
The automatic transmission fluid level
does not need to be checked under
normal usage conditions.
We recommend that the automatic
transmission fluid be changed by an
authorized HYUNDAI dealer according to
the maintenance schedule.
Information
Automatic transmission fluid color is red
when new.
As the vehicle is driven, the automatic
transmission fluid will begin to look
darker.
This is a normal condition. It does not
need to be replaced based on the color
change.
NOTICE
The use of a non-specified fluid could
result in transmission malfunction and
failure.
Use only specified automatic
transmission fluid. (Refer to
“Recommended Lubricants and
Capacities” section in chapter 2.)

minutes and get immediate medical
attention. If acid gets on your skin,
thoroughly wash the area. If you feel
pain or a burning sensation, get medical
attention immediately.
• When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak. Lift with a
battery carrier or with your hands on
opposite corners.
• Do not attempt to jump start your
vehicle if your battery is frozen.
• NEVER attempt to recharge the
battery when the vehicle’s battery
cables are connected to the battery.
