6. Fuel Gauge• The pointer shows the level of fuel in the fuel tankwhen the ignition is in the ON/RUN position.
• The fuel pump symbol points to the side of the vehicle where the fuel door is located.
7. Temperature Gauge
• The gauge pointer shows engine coolant temperature.The pointer positioned within the normal range indi -
cates that the engine cooling system is operating satis -
factorily.
• The gauge pointer will likely indicate a higher tempera -
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.WARNING!
A hot engine cooling system is dangerous. You or others
could be badly burned by steam or boiling coolant. You
may want to call an authorized dealer for service if your
vehicle overheats. If you decide to look under the hood
yourself, see “Servicing And Maintenance.” Follow the
warnings under the Cooling System Pressure Cap
paragraph.
CAUTION!
Driving with a hot engine cooling system could damage
your vehicle. If the temperature gauge reads “H,” pull
over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into
the normal range. If the pointer remains on the “H,” turn
the engine off immediately and call an authorized dealer
for service.

150 GETTING TO KNOW YOUR INSTRUMENT PANEL
— Door Open Warning Light
This indicator will illuminate when a door is ajar/open and
not fully closed.
NOTE:
If the vehicle is moving there will also be a single chime.
Yellow Warning Lights
— Adaptive Cruise Control (ACC) Fault Warning Light
— If Equipped
This warning light will illuminate to indicate a fault in the
ACC system. Contact a local authorized dealer for service.
For further information, refer to “Adaptive Cruise Control
(ACC)” in “Starting And Operating.”
— Engine Check/Malfunction Indicator Warning Light
(MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a
part of an Onboard Diagnostic System called OBD II that
monitors engine and automatic transmission control
systems. This warning light will illuminate when the ignition
is in the ON/RUN position before engine start. If the bulb does not come on when turning the ignition switch from OFF
to ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap, poor
quality fuel, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through
several typical driving styles. In most situations, the vehicle
will drive normally and will not require towing.
When the engine is running, the MIL may flash to alert
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced by an authorized dealer as soon as
possible if this occurs.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you drive
slowly or park over flammable substances such as dry
plants, wood, cardboard, etc. This could result in death
or serious injury to the driver, occupants or others.

— Low Washer Fluid Warning Light — If Equipped
This warning light will illuminate when the windshield
washer fluid is low.
— Low Fuel Warning Light
When the fuel level reaches approximately 3.2 gal (12 L) this
light will turn on, and remain on until fuel is added.
A single warning chime will sound with Low Fuel Warning.
— Low Coolant Level Warning Light
This telltale will turn on to indicate the vehicle coolant level
is low.
— Loose Fuel Filler Cap Warning Light — If Equipped
This warning light will illuminate when the fuel filler cap is
loose. Properly close the filler cap to disengage the light. If
the light does not turn off, please see an authorized dealer. — Tire Pressure Monitoring System (TPMS) Warning
Light
The warning light switches on and a message is displayed to
indicate that the tire pressure is lower than the recom -
mended value and/or that slow pressure loss is occurring. In
these cases, optimal tire duration and fuel consumption may
not be guaranteed.
Should one or more tires be in the condition mentioned
above, the display will show the indications corresponding
to each tire.

Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires
of a different size than the size indicated on the vehicle placard
or tire inflation pressure label, you should determine the
proper tire inflation pressure for those tires.)

CAUTION!

Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle, avoiding
sharp braking and steering. If a tire puncture occurs, repair
immediately using the dedicated tire repair kit and contact
an authorized dealer as soon as possible.

336 STARTING AND OPERATING
(Continued)
Deactivation
Once activated, the image will continue to be displayed in
any gear until the vehicle speed exceeds 8 mph (13 km/h).REFUELING THE VEHICLE — GAS
NOTE:
When the fuel nozzle “clicks” or shuts off the fuel tank is full.
WARNING!
Drivers must be careful when backing up even when
using the Surround View Camera. Always check
carefully behind your vehicle, and be sure to check for
pedestrians, animals, other vehicles, obstructions, or
blind spots before backing up. You are responsible for
the safety of your surroundings and must continue to
pay attention while backing up. Failure to do so can
result in serious injury or death.
CAUTION!
• To avoid vehicle damage, Surround View should only be used as a parking aid. The Surround View camera is
unable to view every obstacle or object in your drive
path.
• To avoid vehicle damage, the vehicle must be driven slowly when using Surround View to be able to stop in
time when an obstacle is seen. It is recommended that
the driver look frequently over his/her shoulder when
using Surround View.
CAUTION!
• Damage to the fuel system or emissions control system could result from using an improper fuel tank filler
tube cap (fuel filler cap). A poorly fitting cap could let
impurities into the fuel system. Also, a poorly-fitted
aftermarket cap can cause the MIL (Malfunction Indi -
cator Light) to illuminate due to fuel vapors escaping
from the system.
• A poorly fitting fuel filler cap may cause the MIL to turn on.
• To avoid fuel spillage and overfilling, do not “top off” the fuel tank after filling.
WARNING!
• Never have any smoking materials lit in or near the vehicle when the gas cap is removed or the tank is
being filled.

STARTING AND OPERATING 337
NOTE:
Tighten the gas cap ¼ turn until you hear one click. This is an
indication that the cap is properly tightened.
If the gas cap is not tightened properly, the Malfunction Indi-
cator Light will come on. Be sure the gas cap is tightened
every time the vehicle is refueled.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the
fuel filler cap is loose, improperly installed, or
damaged, a loose gascap indicator will display in the
instrument cluster telltale display area. Refer to “Instrument
Cluster Display” in “Getting To Know Your Instrument
Panel” for further information. Tighten the fuel filler cap
properly and push the RIGHT button to turn off the message.
If the problem continues, the message will appear the next
time the vehicle is started.
VEHICLE LOADING
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo. The
label also specifies maximum capacities of front and rear axle
systems (GAWR). Total load must be limited so GVWR and
front and rear GAWR are not exceeded.
• Never add fuel to the vehicle when the engine is
running. This is in violation of most state and federal
fire regulations and may cause the MIL to turn on.
WARNING!
A fire may result if gasoline is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place gas containers on the ground
while filling.
