152 GETTING TO KNOW YOUR INSTRUMENT PANEL
— Low Washer Fluid Warning Light — If Equipped
This warning light will illuminate when the windshield
washer fluid is low.
— Low Fuel Warning Light
When the fuel level reaches approximately 3.2 gal (12 L) this
light will turn on, and remain on until fuel is added.
A single warning chime will sound with Low Fuel Warning.
— Low Coolant Level Warning Light
This telltale will turn on to indicate the vehicle coolant level
is low.
— Loose Fuel Filler Cap Warning Light — If Equipped
This warning light will illuminate when the fuel filler cap is
loose. Properly close the filler cap to disengage the light. If
the light does not turn off, please see 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 recom -
mended 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
above, 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.) 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.

182 SAFETY
Vehicles With Non Matching Full Size Spare Or Compact
Spare
• The non matching full size spare or compact spare tire
does not have a TPM sensor. Therefore, the TPMS will not
monitor the pressure in the non matching full size spare or
compact spare tire.
• If you install the non matching full size spare or compact
spare tire in place of a road tire that has a pressure below the
low-pressure warning limit, upon the next ignition switch
cycle, the TPM Telltale Light and a “LOW TIRE” message
will remain ON and a chime will sound. In addition, the
graphic in the instrument cluster will still display a pressure
value in a different color and an “Inflate to XX” message.
• After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the TPM Telltale Light will flash on
and off for 75 seconds and then remain on solid. In addi -
tion, the instrument cluster will display a "SERVICE TPM
SYSTEM" message for a minimum of five seconds and then
display dashes (- -) in place of the pressure value.
• For each subsequent ignition switch cycle, a chime will
sound, the TPM Telltale Light will flash on and off for 75
seconds and then remain on solid, and the instrument
cluster will display a "SERVICE TPM SYSTEM" message for
a minimum of five seconds and then display dashes (- -) in
place of the pressure value. • Once you repair or replace the original road tire and rein -
stall it on the vehicle in place of the non matching full size
spare or compact spare, the TPMS will update automati -
cally. In addition, the TPM Telltale Light will turn OFF and
the graphic in the instrument cluster will display a new
pressure value instead of dashes (- -), as long as no tire
pressure is below the low-pressure warning limit in any of
the four active road tires. The vehicle may need to be
driven for up to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this information.
Trailer Tire Pressure Monitoring System (TTPMS)
The Trailer Tire Pressure Monitoring System (TTPMS) is a
feature that will display the trailer tire pressure values and
warn the driver of a low trailer tire pressure, based on the
drivers set target tire pressure value, through the Instrument
Cluster (IC).
The TTPMS monitors the pressure of each tire and warns the
driver, through the IC, when either a low tire pressure condi -
tion or a TPM sensor or system malfunction condition exists.
The IC will display the actual tire pressure or dashes for each
of the trailer tires in the correct trailer position, based on
trailer configuration.

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)

STARTING AND OPERATING 347
(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)

IN CASE OF EMERGENCY 393
Jack Warning Label 1. If equipped, remove the spare wheel, jack, and tools from
storage.
2. Using the lug wrench, loosen, but do not remove, the lug
nuts by turning them counterclockwise one turn while
the wheel is still on the ground.• To assure that spare tires, flat or inflated, are securely
stowed, spares must be stowed with the valve stem
facing the ground. WARNING! (Continued) CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in the Jacking
Instructions for this vehicle.

IN CASE OF EMERGENCY 395
5. Remove the lug nuts and pull the wheel off. Install the
spare wheel and lug nuts with the cone shaped end of the
nuts toward the wheel on single rear wheel (SRW)
models. On dual rear wheel models (DRW) the lug nuts
are a two-piece assembly with a flat face. Lightly tighten
the nuts. To avoid risk of forcing the vehicle off the jack,
do not fully tighten the nuts until the vehicle has been
lowered.
6. Using the lug wrench, finish tightening the nuts using a
crisscross pattern. For the proper lug nut torque specifica -
tions refer to “Wheel And Tire Torque Specifications” in
“Technical Specifications.” If in doubt about the correct
tightness, have them checked with a torque wrench by an
authorized dealer or at a service station. 7. Install wheel center cap (if equipped) and remove wheel
blocks. Do not install chrome or aluminum wheel center
caps on the spare wheel. This may result in cap damage.
8. Lower the jack to its fully closed position. If the jack will
not lower by turning the dial (thumbwheel) by hand, it
may be necessary to use the jack driver in order to lower
the jack. Stow the replaced tire, jack, and tools as previ -
ously described.
9. Adjust the tire pressure when possible.WARNING!
Raising the vehicle higher than necessary can make the
vehicle less stable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
remove the tire. WARNING!
A loose tire or jack thrown forward in a collision or hard
stop, could endanger the occupants of the vehicle.
Always stow the jack parts and the spare tire in the
places provided.

396 IN CASE OF EMERGENCY
Dual Rear Wheels
Slots in the wheels will assist in properly orienting the inner
and outer wheels. Align these slots when assembling the
wheels for best access to the tire valve on the inner wheel.
The tires of both dual wheels must be completely off the
ground when tightening to insure wheel centering and
maximum wheel clamping.
Dual wheel models require a special heavy-duty lug nut
tightening adapter (included with the vehicle) to correctly
tighten the lug nuts. Also, when it is necessary to remove and
install dual rear wheels, use a proper vehicle lifting device.
NOTE:
When installing a spare tire (if equipped) as part of a dual
rear wheel end combination, the tire diameter of the two
individual tires must be compared. If there is a significant
difference, the larger tire should be installed in a front loca -
tion. The correct direction of rotation for dual tire installa -
tions must also be observed
It is recommended that wheel stud nuts be kept torqued to
specifications at all times. Torque wheel stud nuts to specifi -
cations at each lubrication interval.
Refer to “Wheel And Tire Torque Specifications” in “Tech -
nical Specifications” for further information. Wheel Nuts
All wheel nuts should be tightened occasionally to eliminate
the possibility of wheel studs being sheared or the bolt holes
in the wheels becoming elongated. This is especially
important during the first few hundred miles/kilometers of
operation to allow the wheel nuts to become properly set. All
wheel nuts should first be firmly seated against the wheel.
The wheel nuts should then be tightened to recommended
torque. Tighten the wheel nuts to final torque in increments.
Progress around the bolt circle, tightening the wheel nut
opposite to the wheel nut just previously tightened until
final torque is achieved.
Refer to “Wheel And Tire Torque Specifications” in “Tech -
nical Specifications” for further information.
To Stow The Flat Or Spare — If Equipped
Refer to Upfitters Body Builder’s Guide for information on
stowing your spare tire (if equipped).
