14. RESERVE TANK FLUID (FOR ACTIVE CENTER 
DIFFERENTIAL AND ACTIVE YAW CONTROL 
SYSTEM) (CHECK FLUID LEVEL)

M1001017500013

FLUID LEVEL CHECK

.

<WHEN THE SCAN TOOL IS NOT USED>

1. Remove the trunk room side trim lid on the right of the trunk 

room.

2. If the vehicle has been run, leave it for 90 min. or more in an 

ordinary temperature {10 

− 30° C (50 − 86° F)} to allow the 

accumulator internal pressure to drop.
NOTE: If the ambient temperature is 10

°

C (50

°

F) or less, 

allow more time to leave the vehicle to stand idle.

3. Check that the oil reservoir fluid level is in between MAX and 

MIN.

4. If the fluid level is not in between MAX and MIN, fill the 

specified fluid.

Specified fluid: DIAMOND ATF-SP III

5. Install the trunk room side trim lid.

.

<WHEN THE SCAN TOOL IS USED>

1. Remove the trunk room side trim lid on the right of the trunk 

room.

CAUTION

Turn the ignition switch to the "LOCK (OFF)" position 
before connecting or disconnecting the scan tool.
2. Set the scan tool to the 16-pin data link connector. (Refer to 

P.27-6

.)

3. Turn the ignition switch to the ON position.
4. Using the scan tool, forcibly activate the hydraulic unit (item 

No. 03) to reduce the pressure inside the accumulator. 
(Refer to GROUP 22A 

− Actuator Test Table.)

NOTE: 

.

•

With the forced activation (oil level check mode), the 
hydraulic unit direction valve is operated 20 times to right 
and left, and then the operation is canceled automati-
cally. Also, using the clear key on the scan tool, the acti-
vation can be forcibly canceled.

•

When the functions are suspended by the fail-safe func-
tion, the hydraulic unit cannot be forcibly activated.

5. Check that the oil reservoir fluid level is in between MAX and 

MIN.

6. If the fluid level is not in between MAX and MIN, fill the 

specified fluid.

Specified fluid: DIAMOND ATF-SP III

7. Install the trunk room side trim lid.

15. ENGINE COOLANT (CHANGE)

M1001003100573

1. Remove the engine room under cover front A (RH). (Refer to 

GROUP 51, Under Cover 

P.51-16

)

WARNING

When removing the radiator cap, use care to avoid 
contact with hot coolant or steam. Place a shop towel 
over the cap and turn the cap counterclockwise a lit-
tle to let the pressure escape through the vinyl tube. 
After relieving the steam pressure, remove the cap by 
slowly turning it counterclockwise.

2. Drain the water from the radiator, heater core and engine 

after unplugging the radiator drain plug and removing the 
radiator cap.

3. Remove the engine room under cover front B. (Refer to 

GROUP 51, Under Cover 

P.51-16

)

4. Remove the air cleaner intake hose. (Refer to GROUP 15, 

Air Cleaner 

P.15-10

)

5. Remove the turbocharger compressor bracket. (Refer to 

GROUP 15, Exhaust Manifold and Turbocharger Assembly 

P.15-16

)

6. Disconnect the turbocharger water return hose and drain the 

coolant in the water jacket.

7. Remove the radiator condenser tank and drain the coolant.
8. Drain the coolant then clean the path of the coolant by 

injecting water into the radiator from the radiator cap area.

9. Securely tighten the drain plug of the radiator.
10.Reinstall the radiator condenser tank.

CAUTION

Do not use alcohol or methanol anti-freeze or any engine 
coolants mixed with alcohol or methanol anti-freeze. The 
use of an improper anti-freeze can cause corrosion of the 
aluminum components.
11.By referring to the section on coolant, select an appropriate 

concentration for safe operating temperature within the 
range of 30 to 60%. Use special tool MB991871 to refill the 
engine coolant up to the top of the radiator port. A 
convenient mixture is a 50% water and 50% antifreeze 
solution [freezing point: 

−31° C (−23.8 ° F)].

Recommended antifreeze: Long Life Antifreeze 

Coolant or an equivalent

Quantity: 7.5 dm

3

 (7.9 quarts)

NOTE: For how to use special tool (MB991871), refer to its 
manufacturer’s instructions.

12.Tighten the radiator cap securely.
13.Remove the radiator condenser tank cap, and add the 

engine coolant up to the "FULL" line.

14.Turn the A/C switch to OFF position to start the engine and 

warm up until the cooling fan operates.
NOTE: This step opens the thermostat fully.

15.Rev the engine several times and then stop it. Check that 

there are no coolant leaks.

16.Remove the radiator cap with the engine cool, and then refill 

the engine coolant up to the top of the radiator port.

17.Tighten the radiator cap securely.

CAUTION

Do not overfill the radiator condenser tank.
18.Remove the radiator condenser tank cap, and add the 

engine coolant up to the "FULL" line.

19.Install the turbocharger compressor bracket. (Refer to 

GROUP 15, Exhaust Manifold and Turbocharger Assembly 

P.15-16

)

20.Install the air cleaner intake hose. (Refer to GROUP 15, Air 

Cleaner 

P.15-10

)

21.Remove the engine room under cover front A and engine 

room under cover front A (RH). (Refer to GROUP 51, Under 
Cover 

P.51-16

)

16. COOLANT HOSES (RADIATOR HOSE, 
HEATER HOSE) (INSPECT)

M1001009700175

Inspect the surface of radiator hoses and heater hoses for heat 
and mechanical damage. Hard and brittle rubber, cracking, 
tears, cuts, abrasions and excessive swelling indicate deterio-
ration of the rubber.
