Engine Oil
Checking Engine Oil
It is a good idea to check the
engine oil every time you get fuel.
In order to get an accurate reading,
the oil must be warm and the
vehicle must be on level ground.
The engine oil dipstick handle
is a yellow loop. SeeEngine
Compartment Overview on
page 5-10for the location of
the engine oil dipstick.
1. Turn off the engine and give the
oil several minutes to drain back
into the oil pan. If you do not
do this, the oil dipstick might
not show the actual level.2. Pull out the dipstick and clean
it with a paper towel or cloth,
then push it back in all the way.
Remove it again, keeping the
tip down, and check the level.
When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick,
add at least one quart/liter of the
recommended oil. This section
explains what kind of oil to use.
For engine oil crankcase capacity,
seeCapacities and Specifications
on page 5-96.
Notice:Do not add too much oil.
If the engine has so much oil
that the oil level gets above the
cross-hatched area that shows
the proper operating range,
the engine could be damaged.

Bead:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.
Bias Ply Tire

Service and Appearance Care 5-39

Vehicle Capacity Weight:The
number of designated seating
positions multiplied by 150 lbs
(68 kg) plus the rated cargo load.
SeeLoading the Vehicle on
page 4-16.
Vehicle Maximum Load on the
Tire
:Load on an individual tire
due to curb weight, accessory
weight, occupant weight, and
cargo weight.
Vehicle Placard
:A label
permanently attached to a
vehicle showing the vehicle’s
capacity weight and the original
equipment tire size and
recommended ination pressure.
See “Tire and Loading
Information Label” underLoading
the Vehicle on page 4-16.
Ination - Tire Pressure
Tires need the correct amount
of air pressure to operate
effectively.
Notice:Do not let anyone tell
you that under-ination or
over-ination is all right. It is
not. If your tires do not have
enough air (under-ination),
you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air
(over-ination), you can get
the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road
hazardsA vehicle specic Tire and
Loading Information label is
attached to your vehicle. This
label shows your vehicle’s
original equipment tires and the
correct ination pressures for
your tires when they are cold.
The recommended cold tire
ination pressure, shown on the
label, is the minimum amount of
air pressure needed to support
your vehicle’s maximum load
carrying capacity.
For additional information
regarding how much weight
your vehicle can carry, and an
example of the Tire and Loading
Information label, seeLoading
the Vehicle on page 4-16. How
you load your vehicle affects
vehicle handling and ride
comfort. Never load your vehicle
with more weight than it was
designed to carry.
Service and Appearance Care 5-41

Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inate them to
the proper pressure. Driving on a
signicantly under-inated tire
causes the tire to overheat and can
lead to tire failure. Under-ination
also reduces fuel efficiency and
tire tread life, and may affect the
vehicle’s handling and stopping
ability.
Please note that the TPMS is
not a substitute for proper tire
maintenance, and it is the driver’s
responsibility to maintain correct tire
pressure, even if under-ination
has not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been
equipped with a TPMS malfunction
indicator to indicate when the system
is not operating properly. The TPMS
malfunction indicator is combined
with the low tire pressure telltale.When the system detects a
malfunction, the telltale will ash for
approximately one minute and then
remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as
long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire
pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow
the TPMS to continue to function
properly.

Owner Checks and
Services
These owner checks and services
should be performed at the intervals
specied to help ensure vehicle
safety, dependability, and emission
control performance. Your dealer/
retailer can assist with these checks
and services.
Be sure any necessary repairs are
completed at once. Whenever
any uids or lubricants are added to
the vehicle, make sure they are
the proper ones, as shown in
Recommended Fluids and
Lubricants on page 6-12.
At Each Fuel Fill
It is important to perform these
underhood checks at each fuel fill.
Engine Oil Level Check
Notice:It is important to check
the engine oil regularly and keep it
at the proper level. Failure to keepthe engine oil at the proper level
can cause damage to the engine
not covered by the vehicle
warranty.
Check the engine oil level and add
the proper oil if necessary. See
Engine Oil on page 5-11.
Engine Coolant Level Check
Check the engine coolant level
and add DEX-COOL®coolant
mixture if necessary. SeeEngine
Coolant on page 5-17.
Windshield Washer Fluid
Level Check
Check the windshield washer uid
level in the windshield washer uid
reservoir and add the proper uid if
necessary.
At Least Once a Month
Tire Ination Check
Inspect the vehicle’s tires and make
sure they are inated to the correct
pressures. Do not forget to check
the spare tire, if the vehicle has one.
SeeInflation - Tire Pressure on
page 5-41. If the vehicle has a spare
tire, check to make sure it is stored
securely. SeeChanging a Flat Tire
on page 5-69.
Tire Wear Inspection
Tire rotation may be required for high
mileage highway drivers prior to the
Engine Oil Life System service
notication. Check the tires for wear
and, if necessary, rotate the tires.
SeeTire Inspection and Rotation on
page 5-47.
