2019 - crc - 8/27/18
In Brief 25
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.

Fuel
Regular Unleaded Fuel
Use only Regular 87 octane —(R
+M)/2 —or higher unleaded
gasoline in your vehicle. TOP TIER
Detergent Gasoline is
recommended. Do not use gasoline with an octane rating lower as it will
result in reduced performance and
lower fuel economy. See
Recommended Fuel
0208.
E85 or FlexFuel
FlexFuel Possible
Certain models are compatible with
E85 fuel. See E85 or FlexFuel
0 209.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays the CHANGE ENGINE
OIL SOON message when it is time
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change. Resetting the Oil Life System
1. Using the DIC controls on the right side of the steering wheel,
display REMAINING OIL LIFE
on the DIC. See Driver
Information Center (DIC) 0129.
When remaining oil life is low,
the CHANGE ENGINE OIL
SOON message will appear on
the display.
2. Press
Von the DIC controls
and hold down for a few
seconds to clear the CHANGE
ENGINE OIL SOON message
and reset the oil life at 100%.
Be careful not to reset the oil
life display accidentally at any
time other than after the oil is
changed. It cannot be reset
accurately until the next oil
change.
The oil life system can also be reset
as follows: 1. Display REMAINING OIL LIFE on the DIC. See Driver
Information Center (DIC) 0129.

Extending Engine Run Time
The engine run time can also be
extended by another 15 minutes,
if during the first 15 minutes
Steps 1–3 are repeated while the
engine is still running. An extension
can be requested, 30 seconds after
starting. This provides a total of
30 minutes.
The remote start can only be
extended once.
When the remote start is extended,
the second 15-minute period is
added on to the first 15 minutes and
the engine will run for a total of
30 minutes.
A maximum of two remote starts,
or a remote start with an extension,
is allowed between ignition cycles.The vehicle's ignition must be

. Turn the vehicle on and then off.
Conditions in Which Remote Start
Will Not Work
The remote vehicle start feature will
not operate if:
. The RKE transmitter is in the
vehicle.
. The hood is not closed.
. The hazard warning flashers
are on.
. The malfunction indicator lamp
is on. .
The engine coolant temperature
is too high.
. The oil pressure is low.
. Two remote vehicle starts, or a
single remote start with an
extension, have already
been used.
. The vehicle is not in P (Park).Door Locks
{Warning
Unlocked doors can be
dangerous.
. Passengers, especially
children, can easily open
the doors and fall out of a
moving vehicle. The doors
can be unlocked and
opened while the vehicle is
moving. The chance of
being thrown out of the
vehicle in a crash is
increased if the doors are
not locked. So, all

Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the engine is
started. It provides information
about tire pressures and the TPMS.
When the Light Is On Steady
This indicates that one or more of
the tires are significantly
underinflated.
A Driver Information Center (DIC)
tire pressure message may also
display. Stop as soon as possible,
and inflate the tires to the pressure
value shown on the Tire and
Loading Information label. See Tire
Pressure 0264. When the Light Flashes First and
Then Is On Steady
If the light flashes for about a minute
and then stays on, there may be a
problem with the TPMS. If the
problem is not corrected, the light
will come on at every ignition cycle.
See
Tire Pressure Monitor
Operation 0267.
Engine Oil Pressure Light
Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check
the oil level as soon as possible.
Add oil if required, but if the oil
level is within the operating range
and the oil pressure is still low,
have the vehicle serviced. Always
follow the maintenance schedule
for changing engine oil.
This 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 is near the fuel gauge and
comes on briefly when the ignition is
turned on as a check to show it is
working.

When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
The oil should be changed as soon
as possible. SeeEngine Oil0228.
In addition to the engine oil life
system monitoring the oil life,
additional maintenance is
recommended. See Maintenance
Schedule 0301.
The Oil Life display must be reset
after each oil change. It will not
reset itself. Do not reset the Oil Life
display accidentally at any time
other than when the oil has just
been changed. It cannot be reset
accurately until the next oil change.
To reset the engine oil life system,
press and hold
Vfor several
seconds while the Oil Life display is
active. See Engine Oil Life System

Coolant Temperature : Displays
the coolant temperature in either
degrees Celsius (°C) or degrees
Fahrenheit (°F). Tire Pressure :
Displays the
approximate pressures of all four
tires. Tire pressure is displayed in
either kilopascal (kPa) or in pounds
per square inch (psi). If the pressure
is low, the value for that tire is
shown in amber.
See Tire Pressure Monitor System
0 266 andTire Pressure Monitor
Operation 0267.
Battery Voltage : Displays the
current battery voltage. The battery
voltage can fluctuate while viewing
this information on the DIC. This is
normal.
Speed Signs : Displays sign
information, which comes from a
roadway database in the onboard
navigation.
Vehicle Messages
Messages displayed on the DIC
indicate the status of the vehicle or
some action that may be needed to
correct a condition. Multiple
messages may appear one after
another.
The messages that do not require
immediate action can be
acknowledged and cleared by
pressing
V. The messages that
require immediate action cannot be
cleared until that action is
performed.
All messages should be taken
seriously; clearing the message
does not correct the problem.

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:
.
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 0230.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0225 for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
If a low oil Driver Information Center
(DIC) message displays, check the
oil level.
Follow these guidelines:
. To get an accurate reading, park
the vehicle on level ground.
Check the engine oil level after
the engine has been off for at
least two hours. Checking the
engine oil level on steep grades
or too soon after engine shutoff
can result in incorrect readings.
Accuracy improves when
