6. Fuel Gauge
• The pointer shows the level of fuel in the fuel tank
when 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. 3

— 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. WARNING! (Continued)

338 STARTING AND OPERATING
Payload
The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the driver,
all passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo area
so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle, springs,
tires or wheels). Heavier axles or suspension components
sometimes specified by purchasers for increased durability
does not necessarily increase the vehicle's GVWR.
Tire Size
The tire size on the Vehicle Certification Label represents the
actual tire size on your vehicle. Replacement tires must be
equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size listed. Inflation Pressure
This is the cold tire inflation pressure for your vehicle for all
loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight of
the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo loaded
into the vehicle. The front and rear curb weight values are
determined by weighing your vehicle on a commercial scale
before any occupants or cargo are added.
Loading
The actual total weight and the weight of the front and rear
of your vehicle at the ground can best be determined by
weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commercial
scale to insure that the GVWR has not been exceeded. The
weight on the front and rear of the vehicle should then be
determined separately to be sure that the load is properly
distributed over the front and rear axle. Weighing the vehicle
may show that the GAWR of either the front or rear axles has
been exceeded but the total load is within the specified
GVWR. If so, weight must be shifted from front to rear or

SERVICING AND MAINTENANCE 455
Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause abnormal
wear patterns and reduced tread life, resulting in the need
for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the driver's
side B-Pillar or rear edge of the driver's side door.
At least once a month:
• Check and adjust tire pressure with a good quality
pocket-type pressure gauge. Do not make a visual judge -
ment when determining proper inflation. Tires may look
properly inflated even when they are under-inflated.
• Inspect tires for signs of tire wear or visible damage. Inflation pressures specified on the placard are always “cold
tire inflation pressure”. Cold tire inflation pressure is
defined as the tire pressure after the vehicle has not been
driven for at least three hours, or driven less than 1 mile
(1.6 km) after sitting for a minimum of three hours. The cold
tire inflation pressure must not exceed the maximum infla -
tion pressure molded into the tire sidewall.
Check tire pressures more often if subject to a wide range of
outdoor temperatures, as tire pressures vary with tempera -
ture changes.
Tire pressures change by approximately 1 psi (7 kPa) per 12°F
(7°C) of air temperature change. Keep this in mind when
checking tire pressure inside a garage, especially in the Winter.
Example: If garage temperature = 68°F (20°C) and the
outside temperature = 32°F (0°C) then the cold tire inflation
pressure should be increased by 3 psi (21 kPa), which equals
1 psi (7 kPa) for every 12°F (7°C) for this outside temperature
condition. CAUTION!
After inspecting or adjusting the tire pressure, always
reinstall the valve stem cap. This will prevent moisture
and dirt from entering the valve stem, which could
damage the valve stem.
