intervals.
SCHEDULED MAINTENANCE SERVICES

Checking the engine oil level
Engine oil is used for lubrication and
cooling, so it is gradually consumed
during driving the vehicle.
Regularly check and manage the oil level
using the following procedure.
1. Follow all of the oil manufacturer’s
precautions.
2. Be sure the vehicle is on the level
ground in P (Park) with the parking
brake set and the wheels blocked.
3. Turn the engine on and allow the
engine to reach normal operating
temperature.
4. Turn the engine off and wait about 15
minutes for the oil to return to the oil
pan.
5. Pull the dipstick out, wipe it clean, and
re-insert it fully.
OTMH090002
6. Pull the dipstick out again and check
the level. The level should be between
F (Full) and L (Low).
OTMH090003
7. Check if the oil level is between the
F-L line and refill it if the oil level is
near the L line.
Use only the specified engine oil (Refer
to “Recommended Lubricants and
Capacities” section in chapter 2).
NOTICE
To prevent damage to your engine:
• Do not overfill with engine oil. Add oil
in small quantities and recheck level
to ensure engine is not overfilled.
• The engine oil consumption may
increase while you break in a new
vehicle and it will be stabilized after
driving 3,750 miles.
• The engine oil consumption can be
affected by driving habits, climate
conditions, traffic conditions,
oil quality, etc. Therefore, it is
recommended that you inspect the
engine oil level regularly and refill it
if necessary.
• The engine oil change interval is
set for the purpose of preventing
oil deterioration, and is not related
the amount of oil consumption; so,
check and refill the amount of the oil
regularly.

Maintenance
9-18
Turn the vehicle off and wait until the
engine cools down. Use extreme care
when removing the engine coolant
cap and/or inverter coolant cap. Wrap
a thick towel around it, and turn it
counterclockwise slowly to the first
stop. Step back while the pressure is
released from the cooling system. When
you are sure all the pressure has been
released, press down on the cap, using
a thick towel, and continue turning
counterclockwise to remove it.
Information
The engine coolant and/or inverter coolant
level is influenced by the hybrid system
temperature. Before checking or refilling
the engine coolant and/or inverter coolant,
turn the hybrid vehicle off.
WARNING
The electric motor for the cooling fan may continue to operate or start up
when the engine is not running and
can cause serious injury. Keep hands,
clothing and tools away from the
rotating fan blades of the cooling fan.
Always turn off the vehicle unless the
vehicle has to be inspected with the
engine on. Be cautious as the cooling
fan may operate if the negative (-)
battery terminal is not disconnected.
WARNING
Make sure the coolant cap is properly
closed after refilling coolant. Otherwise
the engine could be overheated while
driving.
