94GETTING TO KNOW YOUR INSTRUMENT PANEL
Vehicle Security Warning Light —
If Equipped
This light will flash at a fast rate for
approximately 15 seconds when the
vehicle security system is arming, and
then will flash slowly until the vehicle is
disarmed.
YELLOW WARNING LIGHTS
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.
Electronic Stability Control (ESC) Active
Warning Light
This warning light will indicate when the
ESC system is Active. The ESC Indicator
Light in the instrument cluster will come
on when the ignition is placed in the
ON/RUN or ACC/ON/RUN position, and when ESC
is activated. It should go out with the engine
running. If the ESC Indicator Light comes on
continuously with the engine running, a
malfunction has been detected in the ESC system.
If this warning light remains on after several
ignition cycles, and the vehicle has been driven
several miles (kilometers) at speeds greater than
30 mph (48 km/h), see an authorized dealer as
soon as possible to have the problem diagnosed
and corrected.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.
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.

21_WD_OM_EN_USC_t.book Page 94

116STARTING AND OPERATING
Track usage results in increased operating
temperatures of the engine, transmission, drive -
line and brake system. This may affect Noise
Vibration Harshness (NVH) countermeasures
designed into your vehicle. New components
may need to be installed to return the system to
the original NVH performance.
Tire pressure:
Recommended tire pressure of 33 psi
(230 kPa) when tires are cold, or below
42 psi (290 kPa) when hot.
NOTE:It is recommended that you target below 42 psi
(290 kPa) when tires are hot at the conclusion of
each track session. Starting at 33 psi (230 kPa)
cold and adjusting based on ambient and track
conditions is recommended. Tire pressure can be
monitored via the instrument cluster display and
can assist with adjustments.
Track burnishing your brakes
To avoid “green lining fade” during track use, the
brake pads and rotors must have a thermal
burnish for factory-installed components or when
new brake friction components are installed:

1. Use one track session to burnish brakes by driving at 75% speed. Brake at approximately
0.60 - 0.80g max without Anti-Lock Brake
System (ABS) intervention.
2. Complete one lap in this manner until you start
smelling the brakes. Continue for another half
lap at speed, then complete a two lap
cooldown with minimal brake applications.
Ensure the brakes are not smoking. If they are,
complete another cooldown lap.
3. Getting the brakes to smoke is an indication that the brakes have overheated and may
negatively affect future track usage.
4. Allow vehicle to sit and cool for at least 30 minutes. If an infrared thermal gun is
available, allow rotors to cool to 200°F
(93.3°C) before returning to the track.
5. There should be a thin layer of ash when inspecting the brake pads. Having the ash
layer go more than half the thickness of the
pad material is a sign of an overly aggressive
burnish.
6. Occasionally, a second burnish session is required. If the brake pads begin to emit an
odor during the next track session, reduce
vehicle speed and braking deceleration rate to
burnish targets and follow steps 2-4. 7. New brake pads installed on old rotors require
a burnish. New rotors installed with old brake
pads should be burnished at the track or
driven for 300 miles (485 km) of city driving to
develop an adequate lining transfer layer on
the rotor surface prior to track use.
8. Rotors that pulsate during track use should be replaced.
NOTE:Resurfacing of the rotors is not recommended, as
it removes mass from the rotor, reducing its
thermal capacity. Resurfacing also thins the rotor
cheek, making it less robust and increasing the
likelihood of pulsation in further track use.
FUEL SAVER TECHNOLOGY 5.7L ONLY —
IF EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and cruise conditions. The system
is automatic with no driver inputs.
NOTE:This system may take some time to return to full
functionality after a battery disconnect.

21_WD_OM_EN_USC_t.book Page 116

140STARTING AND OPERATING
NOTE:If snow, ice, mud, or any foreign substance builds
up on the camera lens, clean the lens, rinse with
water, and dry with a soft cloth. Do not cover the
lens.
Rear View Camera — Viewing At Speed
When the vehicle is in PARK, NEUTRAL or
DRIVE, the Rear View Camera can be
activated with the Rear View Camera
button in the Controls tab of the Vehicle
Menu. This feature allows the customer to monitor
the area directly behind the vehicle (or trailer, if
equipped) for up to 10 seconds while driving. If the
vehicle speed remains below 8 mph (13 km/h),
the Rear View Camera image will be displayed
continuously until deactivated via the X button on
the touchscreen.
REFUELING THE VEHICLE

1. Open the fuel filler door by pushing on the outer edge of the fuel door.

NOTE:There is no fuel filler cap. Two flapper doors inside
the pipe seal the system. 2. Insert the fuel nozzle fully into the filler pipe –
the nozzle opens and holds the flapper doors
while refueling.

Fuel Filler

3. Fill the vehicle with fuel – when the fuel nozzle “clicks” or shuts off the fuel tank is full.
4. Wait five seconds before removing the fuel nozzle to allow fuel to drain from nozzle.
WARNING!
Drivers must be careful when backing up even
when using the ParkView Rear Back Up 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, ParkView should
only be used as a parking aid. The ParkView
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 ParkView 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 ParkView.

STARTING AND OPERATING141
5. Remove the nozzle and push the fuel door all the way in to secure it in place.
VEHICLE LOADING
CERTIFICATION LABEL
As required by National Highway Traffic Safety
Administration regulations, your vehicle has a
certification label affixed to the driver's side door or
pillar.
This label contains the month and year of
manufacture, Gross Vehicle Weight Rating
(GVWR), front and rear Gross Axle Weight Rating
(GAWR), and Vehicle Identification Number (VIN). A
Month-Day-Hour (MDH) number is included on this
label and indicates the Month, Day and Hour of
manufacture. The bar code that appears on the
bottom of the label is your VIN.
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 (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, 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.
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.

142STARTING AND OPERATING
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 141.
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.
CAUTION!
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.

21_WD_OM_EN_USC_t.book Page 142

IN CASE OF EMERGENCY257
Disconnecting The Jumper Cables

1. Disconnect the negative
(-) end of the jumper
cable from the remote negative (-)
post of the
discharged vehicle.

2. Disconnect the opposite end of the negative (-)
jumper cable from the negative (-) post of the
booster battery.
3. Disconnect the positive (+) end of the jumper
cable from the positive (+) post of the booster
battery.
4. Disconnect the opposite end of the positive (+)
jumper cable from the remote positive (+) post
of the discharged vehicle.
5. Reinstall the protective cover over the remote positive (+) post of the discharged vehicle.
If frequent jump starting is required to start your
vehicle have the battery and charging system
tested at an authorized dealer.
REFUELING IN EMERGENCY – IF EQUIPPED
The vehicle is equipped with a refueling funnel for
a Cap-Less Fuel System Úpage 248. If refueling is
necessary, while using an approved gas can, insert
the refueling funnel into the filler neck opening.
Take care to open both flappers with the funnel to
avoid spills.
NOTE:In certain cold conditions, ice may prevent the fuel
door from opening. If this occurs, lightly push on
the fuel door to break the ice buildup and
re-release the fuel door using the inside release
button. Do not pry on the door.

Refueling Funnel
Emergency Gas Can Refueling
Most gas cans will not open the flapper doors. A
funnel is provided to allow emergency refueling
with a gas can.
See below steps for refueling:

1. Retrieve funnel from the spare tire storage
area.

2. Insert funnel into same filler pipe opening as the fuel nozzle.

Inserting Funnel

3. Ensure funnel is inserted fully to hold flapper doors open.
4. Pour fuel into funnel opening.
5. Remove funnel from filler pipe, clean off prior to putting back in the spare tire storage area.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular devices, etc.).
Eventually, if plugged in long enough without
engine operation, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent the engine from starting.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.

258IN CASE OF EMERGENCY
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
In any of the following situations, you can reduce
the potential for overheating by taking the
appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL (N), but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
NOTE:There are steps that you can take to slow down an
impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off. The
A/C system adds heat to the engine cooling
system and turning the A/C off can help remove
this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the heater
core to act as a supplement to the radiator and
aids in removing heat from the engine cooling
system.
MANUAL PARK RELEASE
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.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator.
If you see or hear steam coming from under the
hood, do not open the hood until the radiator
has had time to cool. Never try to open a cooling
system pressure cap when the radiator or
coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads
HOT (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 HOT (H), and you hear
continuous chimes, turn the engine off
immediately and call for service.
WARNING!
Always secure your vehicle by fully applying the
parking brake before activating the Manual Park
Release. In addition, you should be seated in the
driver’s seat with your foot firmly on the brake
pedal when activating the Manual Park Release.
Activating the Manual Park Release will allow
your vehicle to roll away if it is not secured by the
parking brake, or by proper connection to a tow
vehicle. Activating the Manual Park Release on
an unsecured vehicle could lead to serious
injury or death for those in or around the vehicle.
