Checking the Engine Oil Level
1. Make sure that your vehicle is on level ground.
2. Check the oil level before starting the engine, or switch the engine off after
warming up and wait 10 minutes for the
oil to drain into the oil pan. 3. Remove the dipstick and wipe it with a
clean, lint-free cloth.
4. Reinstall the dipstick and make sure it is
fully seated.
5. Remove the dipstick again to check the oil level.
Note: If the oil level is between the maximum
and minimum marks, the oil level is
acceptable. Do not add oil.
6. If the oil level is at the minimum mark, immediately add oil.
7. Reinstall the dipstick. Make sure it is fully
seated.
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.

WARNING: Do not add engine oil
when the engine is hot. Failure to follow
this instruction could result in personal
injury.
Do not use supplemental engine oil additives
because they are unnecessary and could
lead to engine damage that the vehicle
warranty may not cover.
1. Clean the area surrounding the engine oil filler cap before you remove it.
2. Remove the engine oil filler cap.
3. Add engine oil that meets our specifications.
See Capacities and
Specifications (page 402).
4. Reinstall 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: Immediately soak up any oil spillage
with an absorbent cloth. Resetting the Engine Oil Change

CHECKING THE COOLANT
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 459).
Note: Make sure that the coolant level is
between the minimum and maximum marks
on the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between
-29°F (-34°C) and -35°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 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 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 add coolant
further than the MAX mark. 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. 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.
Note: Automotive fluids are not
interchangeable.
It is very important to use prediluted coolant
approved to the correct specification in order
to avoid plugging the small passageways in
the engine cooling system.
See Capacities
and Specifications (page 407). Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine or
cooling system components and could void
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 407).
Using water that has not been deionized
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways.
