1. Tachometer

Indicates the engine speed in revolutions per
minute (RPM x 1000).
2. Voltmeter When the vehicle is in the RUN state, the gauge
indicates the electrical system voltage. The
pointer should stay within the normal range if the
battery is charged. If the pointer moves to either
extreme left or right and remains there during
normal driving, the electrical system should be
serviced.
NOTE:In vehicles equipped with Stop/Start, a reduced voltage
may be present during an Autostop.
3. Instrument Cluster Display
When the appropriate conditions exist, this display
shows the instrument cluster display messages
Úpage 98.
 The display always shows one of the main menu
items after ignition on. 4. Oil Pressure Gauge
The pointer should always indicate the oil pres -
sure when the engine is running. A continuous
high or low reading under normal driving condi -
tions may indicate a lubrication system malfunc -
tion. Immediate service should be obtained from
an authorized dealer.
NOTE:In vehicles equipped with Stop/Start, an oil pressure indi -
cation of zero is normal during an Autostop.
5. Speedometer
Indicates vehicle speed.
6. Temperature Gauge The pointer shows engine coolant temperature.
The pointer positioned within the normal range
indicates that the engine cooling system is oper -
ating satisfactorily.
 The 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. 7. 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.
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
Úpage 350.
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.

Rear Axle Locker Fault Warning Light —
If Equipped
This warning light will illuminate to indicate
when a rear axle locker fault has been
detected.
Service Forward Collision Warning (FCW)
Light — If Equipped
This warning light will illuminate to indicate a
fault in the FCW System. Contact an authorized
dealer for service
Úpage 274.
Service Stop/Start System Warning Light —
If Equipped
This warning light will illuminate when the
Stop/Start system is not functioning properly
and service is required. Contact an authorized
dealer for service.
Service 4WD Warning Light — If Equipped
This warning light will illuminate to signal a fault
with the 4WD system. If the light stays on or
comes on during driving, it means that the 4WD
system is not functioning properly and that
service is required. We recommend you drive to the
nearest service center and have the vehicle serviced
immediately.
Cruise Control Fault Warning Light
This warning light will illuminate to indicate the
Cruise Control System is not functioning
properly and service is required. Contact 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 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 previously
mentioned, 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.
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.
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.
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.

172STARTING AND OPERATING
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 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.
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.
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 ensure 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 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.
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.

23_DT_OM_EN_USC_t.book Page 172

190STARTING AND OPERATING
OFF-ROAD DRIVING TIPS
Care should be taken when attempting to climb steep hills
or driving diagonally across a hill or slope. If natural
obstacles force you to travel diagonally up or down a hill,
choose a mild angle and keep as little side tilt as possible.
Keep the vehicle moving and make turns slowly and
cautiously.
If you must back down a hill, back straight down using
REVERSE gear. Never back down in NEUTRAL or diagonally
across the hill.
When driving over sand, mud, and other soft terrain, shift
to low gear and drive steadily. Apply the accelerator slowly
to avoid spinning the wheels.
Do not reduce the tire pressures for this type of driving.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is always
a good idea to check for damage. That way you can get any
problems taken care of right away and have your vehicle
ready when you need it.
Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
 Inspect the radiator for mud and debris and clean as
required. 
Check threaded fasteners for looseness, particularly
on the chassis, drivetrain components, steering, and
suspension. Retighten them, if required, and torque to
the values specified in the Service Manual.
 Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
 After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.
 If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
CAUTION!
Always check the depth of the standing water before
driving through it. Never drive through standing
water that is deeper than the bottom of the tire rims
mounted on the vehicle.
 Determine the condition of the road or the path that
is under water and if there are any obstacles in the
way before driving through the standing water.
 Do not exceed 5 mph (8 km/h) when driving through
standing water. This will minimize wave effects.
 Driving through standing water may cause damage
to your vehicle’s drivetrain components. Always
inspect your vehicle’s fluids (i.e., engine oil, transmis -
sion, axle, etc.) for signs of contamination (i.e., fluid
that is milky or foamy in appearance) after driving
through standing water. Do not continue to operate
the vehicle if any fluid appears contaminated, as this
may result in further damage. Such damage is not
covered by the New Vehicle Limited Warranty.
 Getting water inside your vehicle’s engine can cause
it to lock up and stall out, and cause serious internal
damage to the engine. Such damage is not covered
by the New Vehicle Limited Warranty.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might not
have full braking power when you need it to prevent a
collision. If you have been operating your vehicle in dirty
conditions, get your brakes checked and cleaned as
necessary.
