This light will come on
briey when you start
your engine.
{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become
so hot that it catches re. You or others
could be burned. Check your oil as soon
as possible and have your vehicle
serviced.Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
That is a check to be sure the light works. If it

When the light comes on and stays on, it means
that oil is not owing through your engine properly.
You could be low on oil and you might have some
other system problem.Security Light
For information
regarding this light,
seeTheft-Deterrent
Systems on page 112.

It cannot be reset accurately until the next oil
change. To reset the engine oil life system, See
Engine Oil Life System on page 368. The display
will show 100% when the system is reset.
UNITS
This display allows you to select between English
or Metric units of measurement. Once in this
display, press the set/reset button to select
between ENGLISH or METRIC units.
PARKING ASSIST
If your vehicle has the Ultrasonic Front and Rear
Parking Assist (UFRPA) system, this display
allows the system to be turned on or off. Once
in this display, press the set/reset button to select
between ON or OFF. If you choose ON, the
system will be turned on. If you choose OFF,
the system will be turned off. The UFRPA system
automatically turns back on after each vehicle
start. When the UFRPA system is turned off and
the vehicle is shifted out of PARK (P), the DIC

as a reminder that the system has been turned
off. SeeDIC Warnings and Messages on page 246
andUltrasonic Front and Rear Parking Assist
(UFRPA) on page 202for more information.
FRONT TIRES or REAR TIRES
The pressure for each tire can be viewed in the
DIC. The tire pressure will be shown in either
pounds per square inch (psi) or kilopascals (kPa).
Press the vehicle information button until the
DIC displays FRONT TIRES PSI (kPa) LEFT ##
RIGHT ##. Press the vehicle information button
again until the DIC displays REAR TIRES
PSI (kPa) LEFT ## RIGHT ##.
If a low or high tire pressure condition is detected
by the system while driving, a message advising
you to check the pressure in a specic tire will
appear in the display. SeeInation - Tire Pressure
on page 411andDIC Warnings and Messages on
page 246for more information.
If the tire pressure display shows dashes instead of
a value, there may be a problem with your vehicle.
If this consistently occurs, see your dealer for
service.

When you reset the CHANGE ENGINE OIL
SOON message by clearing it from the display,
you still must reset the engine oil life system
separately. For more information on resetting
the engine oil life system, seeEngine Oil
Life System on page 368.
CHECK TIRE PRESSURE
This message displays when the tire pressure in
one of the tires needs to be checked. This message
also displays LEFT FRONT, RIGHT FRONT, LEFT
REAR, or RIGHT REAR to indicate which tire needs
to be checked. You can receive more than one tire
pressure message at a time. To read the other
messages that may have been sent at the same
time, press the set/reset button. If a tire pressuremessage appears on the DIC, stop as soon as you
can. Have the tire pressures checked and set to
those shown on the Tire Loading Information label.
SeeTires on page 402,Loading Your Vehicle on
page 333, andInation - Tire Pressure on
page 411. The DIC display also shows the tire
pressure values for the front and rear tires by
pressing the vehicle information button. SeeDIC
Controls and Displays on page 240. If the tire
pressure is low, the low tire pressure warning light
comes on. SeeLow Tire Pressure Warning Light on
page 231.
CLEAN RADAR
This message displays when the Adaptive Cruise
Control (ACC) system and the Forward Collision
Alert (FCA) system are disabled because the radar
is blocked and cannot detect vehicles in your

OIL PRESSURE LOW STOP ENGINE
Notice:If you drive your vehicle while
the engine oil pressure is low, severe engine
damage may occur. If a low oil pressure
warning appears on the instrument panel
cluster and/or DIC, stop the vehicle as soon
as possible. Do not drive the vehicle until
the cause of the low oil pressure is corrected.
SeeEngine Oil on page 365for more
information.
This message displays when the vehicle’s engine
oil pressure is low. The oil pressure light also
appears on the instrument panel cluster.
SeeOil Pressure Light on page 237.
A multiple chime sounds when this message
is displayed. SeeEngine Oil on page 365for
more information.
Stop the vehicle immediately, as engine damage
can result from driving a vehicle with low oil
pressure. Have the vehicle serviced by your
dealer as soon as possible when this message
is displayed.

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 364
for 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.

{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can
boil before the proper coolant mixture will.
Your vehicle’s coolant warning system is
set for the proper coolant mixture. With
plain water or the wrong mixture, your
engine could get too hot but you would
not get the overheat warning. Your engine
could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.
Notice:In cold weather, water can freeze and
crack the engine, radiator, heater core and
other parts. Use the recommended coolant and
the proper coolant mixture.
{CAUTION:
You can be burned if you spill coolant on
hot engine parts. Coolant contains
ethylene glycol and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.
1. You can remove the
coolant surge tank
pressure cap when
the cooling system,
including the coolant
surge tank pressure
cap and upper
radiator hose, is no
longer hot.
Turn the pressure cap slowly counterclockwise.
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.
2. Then keep turning the cap and remove it.
