solid yellow when the vehicle is approaching a
lane marker. The warning light will flash when
the vehicle is crossing the lane marker.
Service Lane Keep Assist Warning Light —
If Equipped
This warning light will illuminate when the Lane
Keep Assist system is not operating and
requires service. Please see an authorized
dealer.
Low Fuel Warning Light
The Low Fuel Warning Light will turn on when
low fuel is detected in the fuel tank.
Engine Check/Malfunction Indicator (MIL)
Warning Light
The 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.
Keyless Enter n’ Go™/Service Passive

and service is required. Contact an authorized
dealer for service.
Tire Pressure Monitoring System (TPMS)
Warning Light — If Equipped
The warning light switches on and a message is
displayed to indicate that the tire pressure is
lower than the recommended 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
previously, the display will show the indications
corresponding to each tire.
WARNING!
A malfunctioning catalytic converter 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.

76GETTING TO KNOW YOUR INSTRUMENT PANEL
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.

As an added safety feature, your vehicle has been equipped
with a TPMS that illuminates a low tire pressure telltale
when one or more of your tires is significantly underinflated.
Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving on a
significantly underinflated tire causes the tire to overheat
and can lead to tire failure. Underinflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.

Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if underinflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale. Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent
vehicle start-ups as long as the malfunction exists. When
the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or
wheels on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to
function properly.
Towing Hook Breakdown Warning Light —
If Equipped
This light illuminates when there is a failure
with the tow hook. Contact an authorized
dealer for service.
Traffic Sign Recognition (TSR) Fault
Warning Light
This light will illuminate to indicate a TSR fault.
Contact an authorized dealer if the light
remains on after restarting the engine.
Transmission Temperature Warning Light
This warning light will illuminate to warn of a
high transmission fluid temperature. This may
occur with strenuous usage such as trailer
towing. If this light turns on, stop the vehicle
and run the engine at idle or slightly faster, with the
transmission in PARK or NEUTRAL, until the light turns off.
Once the light turns off, you may continue to drive
normally.
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.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning 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. Aftermarket wheels can cause
sensor damage. 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 dealer to have your
sensor function checked.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illuminated
you could cause the fluid to boil over, come in contact
with hot engine or exhaust components and cause a
fire.

23_GG_OM_EN_USC_t.book Page 76

STARTING AND OPERATING89
If the “POWER STEERING SYSTEM HOT -
PERFORMANCE MAY BE LIMITED” message
and a steering wheel icon display on the
instrument cluster, it indicates that extreme
steering maneuvers may have occurred, which caused an
over temperature condition in the electric power steering
system. You will lose power steering assistance
momentarily until the over temperature condition no
longer exists. Once driving conditions are safe, pull over
and let the vehicle idle for a few moments until the light
turns off
Úpage 66.
NOTE:
 Even if the power steering system is no longer opera -
tional, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
 If the condition persists, see an authorized dealer for
service.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is designed to reduce fuel
consumption. The system will stop the engine
automatically during a vehicle stop if the required
conditions are met. Releasing the brake pedal or pressing
the accelerator pedal will automatically restart the engine.
This vehicle has been upgraded with a heavy-duty starter,
enhanced battery, and other upgraded engine parts, to
handle the additional engine starts.
AUTOSTOP MODE
The Stop/Start feature is enabled after every normal
customer engine start. At that time, the system will go into
STOP/START READY.
To Activate The Autostop Mode, The Following Must Occur:
The system must be in STOP/START READY state. A
“STOP/START READY” message will be displayed in the
instrument cluster display within the Stop/Start
section
Úpage 66.
 The vehicle must be completely stopped.
 The gear selector must be in a forward gear and the
brake pedal pressed.
The engine will shut down, the tachometer will move to the
zero position, and the Stop/Start telltale will illuminate
indicating you are in Autostop. Customer settings will be
maintained upon return to an engine-running condition.
POSSIBLE REASONS THE ENGINE DOES
N
OT AUTOSTOP
Prior to engine shut down, the system will check many
safety and comfort conditions to see if they are fulfilled.
Detailed information about the operation of the Stop/Start
system may be viewed in the instrument cluster display
Stop/Start Screen. In the following situations the engine
will not stop:
 Driver’s seat belt is not buckled.
 Driver’s door is not closed.
 Battery temperature is too warm or cold. 
Battery charge is low.
 The vehicle is on a steep grade.
 Cabin heating or cooling is in process and an accept -
able cabin temperature has not been achieved.
 HVAC is set to full defrost mode at a high blower speed.
 HVAC is set to MAX A/C.
 Engine has not reached normal operating temperature.
 The transmission is not in a forward gear.
 Hood is open.
 Brake pedal is not pressed with sufficient pressure.
 Accelerator pedal input.
 Engine temperature is too high.
 5 mph (8 km/h) threshold has not been achieved from
previous Autostop.
 Steering angle beyond threshold.
 Adaptive Cruise Control is on and speed is set.
It may be possible for the vehicle to be driven several
times without the Stop/Start system going into a STOP/
START READY state under more extreme conditions of the
items listed previously.

STARTING AND OPERATING121
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
Úpage 120.
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.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR
Úpage 120.
Tongue Weight (TW)
The TW is the downward force exerted on the hitch ball by
the trailer. You must consider this as part of the load on
your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
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!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose control
of the vehicle and have a collision.
