Engine Oil Pressure Light
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule for changing engine oil.
The oil pressure light should come
on briefly as the engine is started.
If it does not come on, have the
vehicle serviced by your dealer.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem. See
your dealer.
Low Fuel Warning Light
This light comes on for a few
seconds when the ignition is turned
on as a check to indicate it is
working. If it does not come on,
have it fixed.
The low fuel warning light comes on
and a chime sounds periodically
when the vehicle is low on fuel. The
light turns off when fuel is added to
the fuel tank.
See Driver Information Center (DIC)
on page 5‑25 for more information.

Battery Level
This display, available on some
vehicles, shows the current battery
voltage. If the voltage is in the
normal range, the value will display.
For example, the display may read
Battery Voltage 15.0 Volts. The
vehicle's charging system regulates
voltage based on the state of the
battery. The battery voltage can
fluctuate while viewing this
information on the DIC. This is
normal.
Power Flow (eAssist Only)
This display shows the operating
mode of the eAssist system and the
high voltage battery charge level.
The animation indicates the
direction of energy flow.Vehicle Information Menu

andTire Pressure
Monitor Operation on page 10‑55 for
more information.
Remaining Oil Life
This display shows an estimate of
the oil's remaining useful life.
If REMAINING OIL LIFE 99% is
displayed, that means 99% of the
current oil life remains.
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
See Engine Oil Messages on
page 5‑31. The oil should be
changed as soon as possible. See
Engine Oil on page 10‑11. In
addition to the Engine Oil Life
System monitoring the oil life,
additional maintenance is
recommended in the Maintenance
Schedule in this manual. See
Maintenance Schedule on
page 11‑3 for more information.
Remember, the Remaining Oil Life
display must be reset after each oil
change. It will not reset itself. Also,

pressure levels occur. Stop the
vehicle as soon as safely possible
and do not operate it until the cause
of the low oil pressure has been
corrected. Check the oil as soon as
possible and have the vehicle
serviced by your dealer.
Engine Power Messages
ENGINE POWER IS REDUCED
This message displays when the
vehicle's engine power is reduced.
Reduced engine power can affect
the vehicle's ability to accelerate.

reduction in performance, proceed
to your destination. The
performance may be reduced the
next time the vehicle is driven. The
vehicle may be driven at a reduced
speed while this message is on, but
maximum acceleration and speed
may be reduced. Anytime this
message stays on, the vehicle
should be taken to your dealer for
service as soon as possible.

Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.Always use engine oil approved
to the proper specification and of
the proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
.Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
.Change the engine oil at the
appropriate time. See Engine Oil
Life System on page 10‑13.
.Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. 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. See
Engine Compartment Overview on
page 10‑6 for the location of the
engine oil dipstick.
Obtaining an accurate oil level
reading is essential:
1. If the engine has been running recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.

10-20 Vehicle Care
These mixtures:
.Give freezing protection down to
−37°C (−34°F), outside
temperature.
.Give boiling protection up to
129°C (265°F), engine
temperature.
.Protect against rust and
corrosion.
.Will not damage aluminum parts.
.Help keep the proper engine
temperature.
Notice: If an improper coolant
mixture is used, the engine could
overheat and be badly damaged.
The repair cost would not be
covered by the vehicle warranty.
Too much water in the mixture
can freeze and crack the engine,
radiator, heater core, and other
parts.
Never dispose of engine coolant by
putting it in the trash, pouring it on
the ground, or into sewers, streams,
or bodies of water. Have the coolant
changed by an authorized service center, familiar with legal
requirements regarding used
coolant disposal. This will help
protect the environment and your
health.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible in
the coolant surge tank. If the coolant
inside the coolant surge tank is
boiling, do not do anything else until
it cools down.
If coolant is visible but the coolant
level is not at or above the mark
pointed to, add:
2.0L Engine and 2.4L Engine
without eAssist
A 50/50 mixture of clean drinkable
water and DEX-COOL coolant.
2.4L Engine with eAssist
A 50/50 mixture of deionized water
and DEX-COOL coolant.
Be sure the cooling system is cool
before this is done.
If no coolant is visible in the coolant
surge tank, add coolant as follows:
How to Add Coolant to the
Coolant Surge Tank
Notice:
This vehicle has a
specific coolant fill procedure.
Failure to follow this procedure
could cause the engine to
overheat and be severely
damaged.
If no problem is found, check to see
if coolant is visible in the coolant
surge tank. If coolant is visible
but the coolant level is not at
the indicated level mark, add a
50/50 mixture of clean, drinkable or
deionized water and DEX-COOL
coolant at the coolant surge tank,
but be sure the cooling system,
including the coolant surge tank
pressure cap, is cool before you
do it.
