3. Speedometer• Indicates vehicle speed.
4. 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.
5. Temperature Gauge
• The pointer shows engine coolant temperature. Thepointer positioned within the normal range indicates
that the engine cooling system is operating satisfacto -
rily.
• The pointer will likely indicate a higher temperature 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. Refer to “Cooling System Pressure
Cap” in “Servicing And Maintenance” for further
information if you decide to look under the hood.
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.

— 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.”
— Air Suspension Fault Warning Light — If Equipped
This light will illuminate when a fault is detected with the air
suspension system. — 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.
CAUTION!
Continuous driving with the Transmission Temperature
Warning Light illuminated will eventually cause severe
transmission damage or transmission failure.

228 SAFETY
(Continued)
NOTE:
When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the recom-
mended cold placard pressure in order to turn the TPMS
Warning Light off.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of 30 psi
(207 kPa). If the ambient temperature is 68°F (20°C) and the
measured tire pressure is 27 psi (186 kPa), a temperature
drop to 20°F (-7°C) will decrease the tire pressure to approx -
imately 23 psi (158 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
27 psi (186 kPa), but the TPMS Warning Light will still be on.
In this situation, the TPMS Warning Light will turn off only
after the tires are inflated to the vehicle’s recommended cold
placard 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.
• Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
CAUTION!
• The TPMS has been optimized for the original equip -
ment 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. After -
market wheels can cause sensor damage.
• Using aftermarket tire sealants may cause the Tire Pres -
sure Monitoring System (TPMS) sensor to become
inoperable. After using an aftermarket tire sealant it is
recommended that you take your vehicle to an autho -
rized 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 TPMS sensor. CAUTION!

STARTING AND OPERATING 403
REFUELING THE VEHICLE
The fuel filler is located behind the fuel filler door, on the left
side of the vehicle.
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.
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 MIL to turn on.
• 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.
CAUTION!
To avoid fuel spillage and overfilling, do not “top off”
the fuel tank after filling.

In certain cold conditions, ice may prevent the fuel filler door
from opening. If this occurs, lightly push on the fuel filler
door around the perimeter to break the ice build up.
Emergency Gas Can Refueling
Most gas cans will not open the flapper doors.
A funnel is provided to open the flapper doors to allow
emergency refueling with a gas can.
1. Retrieve funnel from the jack and jack tool kit.
2. Insert funnel into same filler pipe opening as the fuelnozzle. 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 jack and jack tool kit.
VEHICLE LOADING
Gross Vehicle Weight Rating (GVWR)
The Gross Vehicle Weight Rating (GVWR) is the total
permissible weight of your vehicle including driver, passen -
gers, vehicle, options and cargo. The label also specifies
maximum capacities of front and rear axle systems Gross
Axle Weight Rating (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.
WARNING!
• Always place container on the ground before filling.
• Keep the pump nozzle in contact with the container when you are filling it.
• Use only approved containers for flammable liquid.
• Do not leave container unattended while filling.
• A static electric charge could cause a spark and fire hazard.

406 STARTING AND OPERATING
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 Gross Axle Weight Rating
(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 Gross Vehicle Weight Rating (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 Gross Axle
Weight Rating (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 limita-
tions are met. Store the heavier items down low and be sure

526 SERVICING AND MAINTENANCE
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 qualitypocket-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. 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.
