10-10 Vehicle Care
{ CautionFailure to use the recommended
engine oil can result in engine
damage not covered by the
vehicle warranty. Check with your
dealer or service provider on
whether the oil is approved to the
dexos1 specification. Use of Substitute Engine Oils if
dexos1 is unavailable: In the event
that dexos1-approved engine oil is
not available at an oil change or for
maintaining proper oil level, you
may use substitute engine oil that
meets American Petroleum Institute
(API) approved specifications of the
appropriate viscosity grade. These
oils have the API certification mark
on the front of the container.
Viscosity Grade
Use SAE 5W-30 viscosity grade
engine oil.
Engine Oil Additives/Engine
Oil Flushes Do not add anything to the oil. The
recommended oils meeting the
dexos1 specification are all that is
needed for good performance and
engine protection.
Engine oil system flushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty. What to Do with Used Oil Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer's warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your
own oil, be sure to drain all the oil
from the filter before disposal. Never
dispose of oil by putting it in the
trash or pouring it on the ground,
into sewers, or into streams or
bodies of water. Recycle it by taking
it to a place that collects used oil.

10-14 Vehicle Care What to Use
{ WarningAdding water or some other liquid
to the cooling system can be
dangerous. Water and other
liquids can boil before the proper
coolant mixture will. The coolant
warning system is set for the
proper coolant mixture. With
water or the wrong mixture, the
engine could get too hot but you
would not get the overheat
warning. The engine could catch
fire and you or others could be
burned. Use the recommended
engine coolant. See
Recommended Fluids and
Lubricants on page 11-11 . Use the recommended engine
coolant. See Recommended Fluids
and Lubricants on page 11-11 .
If using this coolant, nothing else
needs to be added. This coolant: .
Gives freezing protection down
to − 37°C ( − 34°F), outside
temperature. .
Gives boiling protection up to
129°C (265°F), engine
temperature. .
Protects against rust and
corrosion. .
Will not damage aluminum parts. .
Helps keep the proper engine
temperature.
{ Caution
If the improper coolant mixture,
inhibitors, or additives are used in
the vehicle cooling system, the
engine could overheat and be
damaged. Too much water in the
(Continued) Caution (Continued) mixture can freeze and crack
engine cooling parts. The repairs
would not be covered by the
vehicle warranty. Use only the
recommended engine coolant for
the cooling system. See
Recommended Fluids and
Lubricants on page 11-11 .
Never dispose of engine coolant by
putting it in the trash, by pouring it

Vehicle Care 10-17If Steam is Coming from the
Engine Compartment
{ WarningSteam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool. Overheated Engine
Protection
Operating Mode The engine has an engine
protection mode to reduce the
chance of damage if the coolant
temperature goes too high (for
example, when climbing steep
grades in high temperature with
heavy loads, such as when towing a
trailer). When the engine
temperature reaches a certain level: .
The engine coolant temperature
warning light will illuminate. .
Engine power may be reduced. .
The air conditioning cooling
function may be automatically
turned OFF for a short time (the
blower will continue to operate).
Engine power and under certain
conditions, vehicle speed will
decrease. Vehicle speed can be
controlled with the accelerator
pedal, but the vehicle may not
accelerate at the desired speed. The transmission will downshift or
upshift as it reaches prescribed shift
points. You can also shift manually.
As driving conditions change and
engine coolant temperature is
reduced, vehicle speed can be
increased using the accelerator
pedal, and air conditioning cooling
function will automatically be turned
back ON.
If:
1. The engine coolant temperature
is not reduced.
2. The air conditioning cooling
function does not turn back ON.
3. The engine oil pressure low/
engine coolant temperature high
warning light illuminates, this
may indicate a malfunction.
Move the vehicle off the road in
a safe area and allow the engine
to cool. If after checking the oil
and coolant, the oil pressure

be damaged or interfere with the car
wash equipment.
Rinse the vehicle well, before
washing and after, to remove all
cleaning agents completely. If they
are allowed to dry on the surface,
they could stain.
Dry the finish with a soft, clean
chamois or an all-cotton towel to
avoid surface scratches and water
spotting.
Finish Care Application of aftermarket clearcoat
sealant/wax materials is not
recommended. If painted surfaces
are damaged, see your dealer to
have the damage assessed and
repaired. Foreign materials such as
calcium chloride and other salts, ice
melting agents, road oil and tar, tree
sap, bird droppings, chemicals from
industrial chimneys, etc., can
damage the vehicle's finish if they
remain on painted surfaces. Wash
the vehicle as soon as possible.
If necessary, use non-abrasive cleaners that are marked safe for
painted surfaces to remove foreign
matter.
Occasional hand waxing or mild
polishing should be done to remove
residue from the paint finish. See
your dealer for approved cleaning
products.
Do not apply waxes or polishes to
uncoated plastic, vinyl, rubber,
decals, simulated wood, or flat paint
as damage can occur.
{ CautionMachine compounding or
aggressive polishing on a
basecoat/clearcoat paint finish
may damage it. Use only
non-abrasive waxes and polishes
that are made for a basecoat/
clearcoat paint finish on the
vehicle.
To keep the paint finish looking new,
keep the vehicle garaged or
covered whenever possible. Protecting Exterior Bright Metal
Moldings
{ CautionFailure to clean and protect the
bright metal moldings can result
