SAFETY 243
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts and
cracks. Inspect sidewalls for cuts, cracks, and bulges. Check
the wheel bolts for tightness. Check the tires (including
spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline fumes
are detected or if fuel, or brake fluid leaks are suspected. The
cause should be located and corrected immediately.• ALWAYS make sure objects cannot fall or slide into the
driver’s side floor area when the vehicle is moving.
Objects can become trapped under accelerator, brake,
or clutch pedals and could cause a loss of vehicle
control.
• NEVER place any objects under the floor mat (e.g.,
towels, keys, etc.). These objects could change the posi -
tion of the floor mat and may cause interference with
the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-installed,
always properly attach carpet to the floor and check the
floor mat fasteners are secure to the vehicle carpet.
Fully depress each pedal to check for interference with
the accelerator, brake, or clutch pedals then re-install
the floor mats.
• It is recommended to only use mild soap and water to
clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners by
lightly pulling mat. WARNING! (Continued)

3. When the shift is complete, the indicator light for the
selected position will stop flashing and remain ON.
If One Or More Of The Following Shift Conditions Are
Not Met:
1. The indicator light for the current position will remain
ON.
2. The newly selected position indicator light will continue
to flash.
3. The transfer case will not shift.
NOTE:
Before retrying a selection, make certain that all the neces -
sary requirements for selecting a new transfer case position
have been met. To retry the selection, push the current posi -
tion, wait five seconds, and retry selection. To find the shift
requirements, refer to the "Shifting Procedure" for your
transfer case, located in this section.
The “SVC 4WD Warning Light” monitors the electronic shift
four-wheel drive system. If this light remains on after engine
start up or illuminates during driving, it means that the
four-wheel drive system is not functioning properly and that
service is required. NOTE:
Do not attempt to make a shift while only the front or rear
wheels are spinning. This could cause damage to driveline
components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 2WD or 4WD
HIGH positions at a given road speed. Take care not to over -
speed the engine and do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles depends on
tires of equal size, type and circumference on each wheel.
Any difference in tire size can cause damage to the drive -
train.
Because four-wheel drive provides improved traction, there
is a tendency to exceed safe turning and stopping speeds. Do
not go faster than road conditions permit. WARNING!
Always engage the parking brake when powering down
the vehicle if the “SVC 4WD Warning Light” is
illuminated. Not engaging the parking brake may allow
the vehicle to roll which may cause personal injury or
death.

NEUTRAL (N)
Neutral — This range disengages both the front and rear
driveshafts from the powertrain. To be used for flat towing
behind another vehicle. Refer to “Recreational Towing” in
“Starting And Operating” for further information.
4L
Four-Wheel Drive Low Range — This range locks the front
and rear driveshafts together forcing the front and rear
wheels to rotate at the same speed. Additional traction and
maximum pulling power for loose, slippery road surfaces
only. Do not exceed 25 mph (40 km/h).
This transfer case is intended to be driven in the 2H position
for normal street and highway conditions such as dry, hard
surfaced roads.
When additional traction is required, the 4H and 4L posi -
tions can be used to lock the front and rear driveshafts
together and force the front and rear wheels to rotate at the
same speed. This is accomplished by simply moving the gear
selector to the desired positions once the appropriate speed
and gear requirements are met, refer to “Shifting Procedure
– Manually Shifted Transfer Case” in this section for further
information. The 4H and 4L positions are intended for loose, slippery road
surfaces only. Driving in the 4H and 4L positions on dry,
hard surfaced roads may cause increased tire wear and
damage to the driveline components.
The “Transfer Case Position Indicator Light” in the instru -
ment cluster will alert the driver that the vehicle is in
four-wheel drive and that the front and rear driveshafts are
locked together. This light will illuminate when the transfer
case is shifted into either the 4H or 4L position. There is no
light for the 2H or NEUTRAL positions on some models.
When operating your vehicle in 4L, the engine speed is
approximately three times that of the 2H or 4H positions at a
given road speed. Take care not to overspeed the engine and
do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles depends on
tires of equal size, type and circumference on each wheel.
Any difference will adversely affect shifting and can cause
damage to the drivetrain.
NOTE:
Do not attempt to make a shift while only the front or rear
wheels are spinning, as this can cause damage to driveline
components.

338 STARTING AND OPERATING
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.
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 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

(Continued) Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact spare
tire.
• Do not drive more than 50 mph (80 km/h) when towing
while using a full size spare tire.WARNING!
• Make certain that the load is secured in the trailer and
will not shift during travel. When trailering cargo that
is not fully secured, dynamic load shifts can occur that
may be difficult for the driver to control. You could lose
control of your vehicle and have a collision.
• When hauling cargo or towing a trailer, do not overload
your vehicle or trailer. Overloading can cause a loss of
control, poor performance or damage to brakes, axle,
engine, transmission, steering, suspension, chassis
structure or tires.
• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
• Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle transmission in PARK. For
four-wheel drive vehicles, make sure the transfer case
is not in NEUTRAL. Always, block or "chock" the
trailer wheels.
• GCWR must not be exceeded. • Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
• GVWR
• GTW
• GAWR
• Tongue weight rating for the trailer hitch utilized. WARNING! (Continued)

348 STARTING AND OPERATING
• Proper tire inflation pressures are essential to the safe and
satisfactory operation of your vehicle. Refer to “Tires” in
“Servicing And Maintenance” for proper tire inflation
procedures.
• Check the trailer tires for proper tire inflation pressures
before trailer usage.
• Check for signs of tire wear or visible tire damage before
towing a trailer. Refer to “Tires” in “Servicing And Main -
tenance” for the proper inspection procedure.
• When replacing tires, refer to “Tires” in “Servicing And
Maintenance” for the proper tire replacement procedures.
Replacing tires with a higher load carrying capacity will
not increase the vehicle's GVWR and GAWR limits.
Towing Requirements — Trailer Brakes
• Do not interconnect the hydraulic brake system or vacuum
system of your vehicle with that of the trailer. This could
cause inadequate braking and possible personal injury.
• An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu -
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic brake
controller is not required. • Trailer brakes are recommended for trailers over 1,000 lbs
(453 kg) and required for trailers in excess of 2,000 lbs (907 kg).
WARNING!
• Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have brakes
when you need them and could have an accident.
• Towing any trailer will increase your stopping
distance. When towing, you should allow for addi -
tional space between your vehicle and the vehicle in
front of you. Failure to do so could result in an accident.
CAUTION!
If the trailer weighs more than 1,000 lbs (453 kg) loaded,
it should have its own brakes and they should be of
adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal effort,
and longer stopping distances.
