To check the engine oil level consistently
and accurately, do the following:
1.
Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N).
2. Run the engine until it reaches normal operating temperature.
3. Make sure that your vehicle is on level ground.
4. Switch the engine off and wait 15 minutes
for the oil to drain into the oil pan.
Checking the engine oil level too soon
after you switch the engine off may result
in an inaccurate reading.

5. Open the hood. See Opening and
Closing the Hood (page 301).
6. Remove the dipstick and wipe it with a clean, lint-free cloth.
See Under Hood
Overview (page 303).
7. Reinstall the dipstick and remove it again
to check the oil level. See Under Hood
Overview
(page 303).
8. Make sure that the oil level is between the maximum and minimum marks. If the
oil level is at the minimum mark, add oil
immediately.
See Capacities and
Specifications (page 372).
9. If the oil level is correct, replace the dipstick and make sure it is fully seated.
Note: Do not remove the dipstick when the
engine is running.
Note: If the oil level is between the
maximum and minimum marks, the oil level
is acceptable. Do not add oil.
Note: The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km)
. Adding Engine Oil WARNING:
Do not remove the filler
cap when the engine is running.
Do not use supplemental engine oil additives
because they are unnecessary and could
lead to engine damage that may not be
covered by the vehicle Warranty. Only use oils certified for gasoline engines
by the American Petroleum Institute (API).
An oil with this trademark symbol conforms
to the current engine and emission system
protection standards and fuel economy
requirements of the International Lubricants
Specification Advisory Committee (ILSAC).
To top up the engine oil level do the
following:
1. Clean the area surrounding the engine
oil filler cap before you remove it.
2. Remove the engine oil filler cap.
See
Under Hood Overview (page 303). Turn
it counterclockwise and remove it.
3. Add engine oil that meets our specifications.
See Capacities and
Specifications (page 372). You may have
to use a funnel to pour the engine oil into
the opening.
4. Recheck the oil level.
5. If the oil level is correct, replace the dipstick and make sure it is fully seated.
6. Replace the engine oil filler cap. Turn it clockwise until you feel a strong
resistance.

Note:
Do not add oil further than the
maximum mark. Oil levels above the
maximum mark may cause engine damage.
Note: Make sure you install the oil filler cap
correctly.
Note: Soak up any spillage with an
absorbent cloth immediately.

ENGINE COOLANT CHECK WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury.

WARNING: Do not put coolant in the
windshield washer reservoir. If sprayed on
the windshield, coolant could make it
difficult to see through the windshield. WARNING: To reduce the risk of
personal injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling system is
under pressure. Steam and hot liquid can
come out forcefully when you loosen the
cap slightly. WARNING:
Do not add coolant
further than the MAX mark.
When the engine is cold, check the
concentration and level of the coolant at the
intervals listed in the scheduled maintenance
information.
See Scheduled Maintenance
(page 475).
Note: Make sure that the coolant level is
between the
MIN and the MAX marks on
the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark. Note:
Automotive fluids are not
interchangeable. Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -30°F (-34°C) and -34°F (-37°C).
Coolant concentration should be checked
using a refractometer. We do not recommend
the use of hydrometers or coolant test strips
for measuring coolant concentration.
Adding Coolant WARNING:
Do not add engine
coolant when the engine is on or the
cooling system is hot. Failure to follow this
instruction could result in personal injury. WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury.
It is very important to use prediluted coolant
meeting the correct specification in order to
avoid plugging the small passageways in the
engine cooling system. See Capacities and
Specifications
(page 372). Incorrect
prediluted coolant use can cause damage
not covered by the vehicle Warranty.
Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water.
See
Capacities and Specifications (page 365).
Using water that has not been deionized
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways.
