Ú page 337.
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
previously referenced, 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.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the
vehicle control system. It also could affect fuel
economy and driveability. If the MIL is flashing,
severe catalytic converter damage and power
loss will soon occur. Immediate service is
required.

REVERSE, then shifted to DRIVE, the camera delay
view will display the standard Back Up Camera
view. If the vehicle is then returned to REVERSE
gear from DRIVE, the Zoom View selection will
automatically resume.
Shifting to NEUTRAL from any gear will maintain
the selected view (Zoom or Standard) as long as
the vehicle speed is below 8 mph (13 km/h).
If the vehicle is in PARK, Zoom View is available
until the gear selector is placed in DRIVE or
REVERSE and speeds are at or above 8 mph
(13 km/h).
NOTE:
If the vehicle is in DRIVE, NEUTRAL, or REVERSE,
and speed is greater than or equal to 8 mph

Fuel Filler Door

NOTE:
In certain cold conditions, ice may prevent
the fuel door from opening. If this occurs,
lightly push around the perimeter of the fuel
door to break the ice buildup.
There is no fuel filler cap. Two flapper doors
inside the pipe seal the system.
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.

5. Remove the fuel nozzle and close the fuel door. Engage the fuel door latch by pushing on
the rear outer edge near the center.
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 Vehicle Certification Label
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.
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 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 do 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.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc
-
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.

23_WL_OM_EN_USC_t.book Page 184

STARTING AND OPERATING185
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 ensure 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 rear to front as appropriate until the
specified weight limitations are met. Store the heavier items down low and be sure that the
weight is distributed equally. Stow all loose items
securely before driving.
Improper weight distributions can have an adverse
effect on the way your vehicle steers and handles
and the way the brakes operate.
TRAILER TOWING
In this section you will find safety tips and
information on limits to the type of towing you can
reasonably do with your vehicle. Before towing a
trailer, carefully review this information to tow your
load as efficiently and safely as possible.
To maintain the New Vehicle Limited Warranty
coverage, follow the requirements and
recommendations in this manual concerning
vehicles used for trailer towing.
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will
assist you in understanding the following
information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers, cargo
and tongue weight. The total load must be limited
so that you do not exceed the GVWR Ú
page 184.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight
of all cargo, consumables and equipment
(permanent or temporary) loaded in or on the
trailer in its "loaded and ready for operation"
condition.
The recommended way to measure GTW is to put
your fully loaded trailer on a vehicle scale. The
entire weight of the trailer must be supported by
the scale.
WARNING!
Do not load your vehicle any heavier than the
GVWR or the maximum front and rear GAWR. If
you do, parts on your vehicle can break, or it can
change the way your vehicle handles. This could
cause you to lose control. Overloading can
shorten the life of your vehicle.
WARNING!
If the gross trailer weight is 5,000 lb (2,267 kg)
or more, it is recommended to use a
weight-distributing hitch to ensure stable
handling of your vehicle. If you use a standard
weight-carrying hitch, you could lose control of
your vehicle and cause a collision.

SAFETY265
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (28 kPa)
above the recommended cold placard pressure in
order to turn the TPMS Warning Light off.
The system will automatically update and the
TPMS Warning Light will extinguish once the
updated tire pressures have been received. The
vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) to receive this
information.
For example, your vehicle has a recommended
cold (parked for more than three hours) tire
pressure of 36 psi (248 kPa). If the ambient
temperature is 68°F (20°C) and the measured tire
pressure is 28 psi (193 kPa), a temperature drop
to 20°F (-7°C) will decrease the tire pressure to
approximately 24 psi (165 kPa). This tire pressure
is sufficiently low enough to turn on the TPMS
Warning Light. Driving the vehicle may cause the
tire pressure to rise to approximately 28 psi
(193 kPa), but the TPMS Warning Light will still be
on. In this situation, the TPMS Warning Light will
turn off only after the tires have been inflated to
the vehicle’s recommended cold tire pressure
value.NOTE:
The TPMS is not intended to replace normal tire
care and maintenance, or to provide warning of
a tire failure or condition.
The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure, unless
equipped with Tire Fill Alert.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel effi -
ciency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility
to maintain correct tire pressure using an accu -
rate tire gauge, even if underinflation has not
reached the level to trigger illumination of the
TPMS Warning Light.
Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual
tire pressure in the tire.
CAUTION!

The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warnings have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may result
when using replacement equipment that is not
of the same size, type, and/or style. The TPMS
sensor is not designed for use on aftermarket
wheels and may contribute to a poor overall
system performance or sensor damage.
Customers are encouraged to use Original
Equipment Manufacturer (OEM) wheels to
ensure proper TPMS feature operation.

Using aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an authorized
dealership to have your sensor function
checked.
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 Tire Pres -
sure Monitoring System sensor.
