Life of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style
•Tire pressure
•Distance driven
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have an accident resulting
in serious injury or death.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. (Refer to the paragraph on
“Tread Wear Indicators”). Refer to the “Tire and Loading
Information” placard for the size designation of your tire.
The service description and load identification will be
found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability.

CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures 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 dam-
age. Do not use aftermarket tire sealants or balance
beads if your vehicle is equipped with a TPMS, as
damage to the sensors may result.
•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 tire pressure moni-
toring sensor.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.
•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire gauge, even
if under-inflation has not reached the level to trigger
illumination of the “Tire Pressure Monitoring Telltale
Light.”

the fault condition no longer exists. A system fault can
occur by any of the following scenarios: 1) Jamming due
to electronic devices or driving next to facilities emitting
the same radio frequencies as the TPM sensors; 2) Install-
ing some form of aftermarket window tinting that affects
radio wave signals; 3) Lots of snow or ice around the
wheels or wheel housings; 4) Using tire chains on the
vehicle; 5) Using wheels/tires not equipped with TPM
sensors.
NOTE: Your vehicle is equipped with a non-matching
full size spare wheel and tire assembly.
1. This spare tire does not have a tire pressure monitor-
ing sensor. Therefore, the TPMS will not monitor the tire
pressure in the spare tire.
2. If you install the full size spare tire in place of a road
tire that has a pressure below the low-pressure warninglimit, upon the next ignition key cycle a chime will sound
and the “TPM Telltale Light” will still turn ON due to the
low tire.
3. However, after driving the vehicle for up to 20 min-
utes above 15 mph (25 km/h), the “TPM Telltale Light”
will flash on and off for 75 seconds and then remain on
solid.
4. For each subsequent ignition key cycle, a chime will
sound and the “TPM Telltale Light” will flash on and off
for 75 seconds and then remain on solid.
5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the full size spare tire,
the TPMS will update automatically and the “TPM
Telltale Light” will turn OFF, 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 (25 km/h) in order for the
TPMS to receive this information.

WARNING! (Continued)
•Never add fuel to the vehicle when the engine is
running. This is in violation of most state and
federal regulations and will cause the “Malfunc-
tion Indicator Light (MIL)” to turn on.
•A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle or on
a truck bed. You could be burned. Always place
gas containers on the ground while filling.
NOTE:
•If fuel is poured from a portable container, the con-
tainer should have a flexible nozzle long enough to
extend into the fuel filler tube.
•When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
•Tighten the gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is properly
tightened. Make sure that the gas cap is tightened each
time the vehicle is refueled.
Loose Fuel Filler Cap Message
After fuel has been added, the vehicle diagnostic system
can determine if the fuel filler cap is possibly loose,
improperly installed, or damaged. If the system detects a
malfunction, the “gASCAP” message will display in the
odometer display. Tighten the gas cap until a clicking
sound is heard. This is an indication that the gas cap is
properly tightened. Press the odometer reset button to
turn the message off. If the problem persists, the message
will appear the next time the vehicle is started. This
might indicate a damaged cap. If the problem is detected
twice in a row, the system will turn on the MIL. Resolving
the problem will turn the MIL off.

NOTE: Before raising the wheel off the ground, make
sure that the jack will not damage surrounding truck
parts and adjust the jack position as required.
5. By rotating the wheel wrench clockwise, raise the
vehicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle unstable and cause an accident. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
6. Remove the wheel nuts and pull the wheel off. Install
the spare wheel and wheel nuts with the cone shaped end
of the nuts toward the wheel. 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.
7. Using the wheel wrench, finish tightening the nuts in
a crisscross pattern. The correct nut tightness is 120 to
160 ft lbs (163 to 217 N·m). If in doubt about the correct
tightness, have them checked with a torque wrench by
your authorized dealer or at a service station.

WARNING!
When temperatures are below the freezing point,
electrolyte in a discharged battery may freeze. Do not
attempt jump-starting because the battery could rup-
ture or explode and cause personal injury. Battery
temperature must be brought above freezing point
before attempting a jump-start.
Preparations for Jump-Start
The battery in your vehicle is located in the front of the
engine compartment, behind the left headlight assembly.

8. Disconnect the opposite end of the positive(+)jumper
cable from the positive (+)post of the booster battery.
9. Disconnect the positive (+)end of the jumper cable
from the positive (+)post of the discharged vehicle.
10. Reinstall the air intake duct.
If frequent jump-starting is required to start your vehicle
you should have the battery and charging system in-
spected at your authorized dealer.
CAUTION!
Accessories that can be plugged into the vehicle
power outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the vehicle’s
battery will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.
FREEING A STUCK VEHICLE
If vehicle becomes stuck in snow, sand, or mud, it can
often be moved by a rocking motion. Move the shift lever
rhythmically between FIRST and REVERSE, while apply-
ing slight pressure to the accelerator.
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause damage, or
even failure, of the axle and tires. A tire could
explode and injure someone. Do not spin your vehi-
cle’s wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without stop-
ping when you are stuck. And do not let anyone near
a spinning wheel, no matter what the speed.
The least amount of accelerator pedal pressure to main-
tain the rocking motion without spinning the wheels or
racing the engine is most effective. Allow the engine to

•Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, also keep the front of
the condenser clean.
•Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine coolant (antifreeze)
performance, poor gas mileage, and increased
emissions.
Brake System
Fluid Level Check – Brake Master Cylinder
The fluid level in the master cylinder should be checked
whenever the vehicle is serviced, or immediately if the
“Brake Warning Light” is on. If necessary, add fluid to
bring level to the full mark on the side of the reservoir of
the brake master cylinder. Be sure to clean the top of the
master cylinder area before removing the cap. With disc
brakes, the fluid level can be expected to fall as the brake
pads wear. Brake fluid level should be checked when
pads are replaced. If the brake fluid level is abnormally
low, check the system for leaks.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
