(1) Select engine oil of the proper SAE viscosity
number according to the atmospheric tem- perature. Recommended viscosity is given in the fol- lowing illustration.

2. Diesel Engine
(1) Select engine oil of the proper SAE viscosity number according to the atmospheric tem- perature.Recommended viscosity is given in the fol- lowing illustration.
NOTE: For diesel-powered vehicle (2.5 TCI only) SAE 5W-30 oil should be used only in areas where extremely cold temperatures of 10°C(50°F) or below are experienced. For diesel-powered vehicle (2.5 TCI only), ifthe atmospheric temperatures are 0°C (32°F) or below, SAE 30 oil must not be used. This oil should be used only in areas where the atmospheric temperatures are 0°C (32°F) or above.
(2) The engine oil quality should meet the fol-lowing API classification:
Diesel Engine (2.5 TCI) : CF-4 or ABOVE Diesel Engine (2.9 CRDi) : CF-4 or ABOVE

G030C01A-AAT To Check the Oil LevelBefore checking the oil, warm up the engine to the normal operating temperature and be sure your car is parked on level ground. Turn the engine off.
G030C02HP-1
NOTE: Before checking or adding the engine oil, remove the cover above the engine oil filler cap and the engine oil level dipstick with a blade screwdriver inserted in the notch (2.5 TCI only).

G350A01A-GAT ENGINE OIL CONSUMPTION Function of Engine Oil Engine oil has the primary function of lubricat- ing and cooling the inside of the engine. Engine oil consumption It is normal that an engine should consume
some engine oil while normal driving. The cause of oil consumption in a normal engine are as follows;
o Engine oil is used to lubricate pistons, piston rings and cylinders. A thin film of oil is left on the cylinder wall
when a piston moves downwards in the cylinder. High negative pressure generated during engine operation sucks some of the oil into the combustion chamber. This oil with some oil of the cylinder wall is
burned by the high temperature combustion gases during the combustion process.
1. Remove the oil filler cap by turning it counter-
clockwise.
2. Add oil, then check the level again. Do not overfill.
3. Replace the cap by turning it clockwise. The distance between the "F" and "L" marks is equal to about 1 liter of oil.

Wait a minute, then remove the dipstick, wipe it off, fully reinsert the dipstick and withdraw it again. Then note the highest level the oil has reached on the dipstick. It should be between the upper ("F") and lower ("L") range. If the oil level is close to or below the "L" mark, add oil until it reaches the "F" mark. To add oil:

The engine oil and filter should be changed at those intervals specified in the maintenance schedule in Section 5. If the car is being driven in severe conditions, more frequent oil and filter changes are required. The procedure for changing the oil and filter is as follows:
1. Park the car on level ground and set theparking brake. Start the engine and let it warm up until the needle on the coolant temperature gauge moves above the lowest mark. Turn the engine off and place the gear selector lever in "P" (automatic transmis- sion) or reverse gear (manual transmis- sion).
2. Open the hood and remove the engine oil filler cap.
3. Slide underneath the car and loosen the drain plug by turning it counterclockwise with a wrench of the proper size. Be sure that a drain pan is in position to catch the oil as it drains out, then remove the drain plug.
WARNING: Be very careful when draining the engine oil
as it may be hot enough to burn you!
4. When the oil has stopped draining, replace
the drain plug using a new washer and retighten by turning it clockwise. Oil pan drain plug tightening torque: 3.5 ~ 4.5 kgf.m
5. Remove the oil filter by turning it counter- clockwise with a oil filter wrench of theproper size. A certain amount of oil will come out when you remove the filter. So be sure to have your drain pan in place under- neath it.
6. Install a new oil filter in accordance with the instructions on the carton or on the filteritself. Do not over-tighten (Tightening
torque: Gasoline- 1.2 ~ 1.6 kgf .
m, Diesel
- 2.3 ~ 2.5 kgf .
m). Be sure that the mounting
surface on the engine is clean and that theold gasket is removed completely. Lubricate the new gasket on the filter with clean en- gine oil before installation.
7. Refill the crankcase with the recommended engine oil. Refer to the specification in chap-ter 9 for engine oil capacity.

G040A02HP-GAT CHANGING THE OIL AND FILTER
o The engine oil consumption is strongly ef-
fected by the viscosity and quality of oil, engine rpm and driving condition etc. The engine oil is more consumed under severe driving conditions such as high speeds and
frequent acceleration and deceleration than normal driving condition.

To Check the Coolant Level

Use a high quality ethylene-glycol coolant in a 50/50 mix with water. The engine coolant should be compatible with aluminum engine parts. Additional corrosion inhibitors or additives should not be used. The cooling system must be main- tained with the correct concentration and type of engine coolant to prevent freezing and corro-

8. Start the engine and check to be sure no oil
is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil level. NOTE: Always dispose of used engine oil in anenvironmentally acceptable manner. It is sug- gested that it be placed in a sealed container and taken to a service station for reclama- tion. Do not pour the oil on the ground or put it into the household trash. WARNING: Used motor oil may cause irritation or can- cer of the skin if left in contact with the skin for prolonged periods of time. Wash your hands thoroughly with soap and warm wa- ter as soon as possible after handling used oil. G050A01A-AAT CHECKING AND CHANGING THE EN- GINE COOLANT WARNING: Do not remove the radiator cap when the engine is hot. When the engine is hot, the engine coolant is under pressure and may erupt through the opening if the cap is removed. You could be seriously burned if you do not observe this precaution. Do not remove the radiator cap until the radiator is cool to touch.
