Center Lap Belts
The center seating position for the Quad Cab front seat
has a lap belt only. To fasten the lap belt, slide the latch
plate into the buckle until you hear a  click.  To lengthen
the lap belt, tilt the latch plate and pull. To remove slack,
pull the loose end of the webbing. Wear the lap belt snug
against the hips. Sit back and erect in the seat, then adjust
the belt as tightly as is comfortable. WARNING!• A lap belt worn too loose or too high is dangerous.
• A belt worn too loose can allow you to slip down
and under the belt in a collision.
• A belt that is too loose or too high will apply crash
forces to the abdomen, not to the stronger hip
bones. In either case, the risk of internal injuries
is greater. Wear a lap belt low and snug.
Seat Belt Pretensioners
The seat belts for both front seating positions are
equipped with pretensioning devices that are designed to
remove slack from the seat belt system in the event of a
collision. These devices improve the performance of the
seat belt by assuring that the belt is tight about the
occupant early in a collision. Pretensioners work for all
size occupants, including those in child restraints. THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 45

•You will then be asked to give your cellular phone a
priority level between 1 and 7, 1 being the highest
priority. You can pair up to seven cellular phones to
your UConnect™ system. However, at any given time,
only one cellular phone can be in use, connected to
your UConnect™ System. The priority allows the
UConnect™ system to know which cellular phone to
use if multiple cellular phones are in the vehicle at the
same time. For example, if priority 3 and priority 5
phones are present in the vehicle, the UConnect™
system will use the priority 3 cellular phone when you
make a call. You can select to use a lower priority
cellular phone at any time (refer to Advanced Phone
Connectivity).
Call/Dial by Saying a Number
•
Press the ’Phone’ button to begin.
•After the Readyprompt and the following beep, say
Dial.
•System will prompt you to say the number you want
call.
•For example, you can say “234-567-8901.” The phone
number that you enter must be of valid length and
combination. Based on the Country in which the
vehicle was purchased, the UConnect™ limits the user
from dialing invalid combination of numbers. For
example, in USA, 234-567-890 is nine digits long,
which is not a valid USA phone number - the closest
valid phone number has ten digits.
•The UConnect™ system will confirm the phone num-
ber and then dial. The number will appear in the
display of certain radios.
Call/Dial by Saying a Name
•
Press the “Phone” button to begin.
•After the Readyprompt and the following beep, say
“Dial” or Call.

There is an additional Power Outlet inside the center
console of vehicles equipped with 40/20/40, or Bucket
front seats. There is also a Power Outlet located on the
rear of the center console for Quad Cab or Mega Cab
vehicles (only) equipped with bucket seats.
The outlet(s) has/have a fused direct feed from the
battery so it/they receive power whether the ignition is
ON or OFF.
All accessories connected to this/these outlet(s) should
be removed or turned OFF when the vehicle is not in use
to protect the battery against discharge.
NOTE: If desired, all of the power outlets can be
converted by your authorized dealer to provide power
with the ignition switch in the ON position only. CAUTION!Electrical Outlet Use With Engine Off
• Many accessories that can be plugged in 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 engine starting.
• Accessories that draw higher power (i.e. coolers,
vacuum cleaners, lights, etc.), will discharge the
battery even more quickly. Only use these inter-
mittently and with greater caution.
• After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
generator to recharge the vehicle’s battery.150 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

removable coin holder (if equipped), and two dividers to
configure the storage area into compartments. For ex-
ample, compartments can be configured to hold a lap-top
computer, a cellular telephone, CD’s and miscellaneous
items. The top of the cover provides a generous firm
surface to serve as a desktop for your “mobile office.”
WARNING!• This armrest is not a seat. Anyone seated on the
armrest could be seriously injured during vehicle
operation, or an accident. Only use the center
seating position when the armrest is fully upright.
• In an accident, the latch may open if the total
weight of the items stored exceeds about 10 lbs
(4.5 kg). These items could be thrown about
endangering occupants of the vehicle. Items
stored should not exceed a total of 10 lbs (4.5 kg). CAUTION!• Many accessories that can be plugged in draw
power from the vehicle’s battery, even when not
in use (i.e. cellular phones, etc.). Eventually, if

INSTRUMENT CLUSTER DESCRIPTION
1. Check Gages
This light illuminates when the Voltmeter, Engine
Oil Pressure or Engine Coolant Temperature
gages indicate a reading either too high or too low.
Examine the gages carefully, and follow the instructions
above for each indicated problem.
NOTE: When the ignition switch is turned to OFF, the
Fuel Gage, Voltmeter, Oil Pressure and Engine Coolant
Temperature gages may not show accurate readings.
When the engine is not running, turn the ignition switch
to ON to obtain accurate readings.
2. Voltmeter
When the engine is running, 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 sys-
tem should be serviced.
NOTE: If the gauge pointer moves to either extreme of
the gauge, the “Check Gages” indicator will illuminate
and a single chime will sound.
NOTE:
• The voltmeter may show a gauge fluctuation if certain
engine temperatures are below 66°F (19°C). This cy-
cling operation is caused by the post-heat cycle of the
intake manifold heater system. The number of cycles
and the length of the cycling operation is controlled by
the engine control module, this time will not exceed
150 seconds. The needle should then stabilize at the
approximate operation point.
• The cycling action will cause temporary dimming of
the headlamps, interior lamps, and also a noticeable
reduction in blower motor speed.172 UNDERSTANDING YOUR INSTRUMENT PANEL

Follow the steps in the Normal Starting Procedure ex-
cept:
CAUTION!Do not crank engine for more than 15 seconds at a
time or starter motor damage may result. Turn key to
OFF and wait at least 2 minutes for starter to cool
before repeating start procedure.
• The WAIT TO START light will remain on for a period
of time (length of time depends on engine tempera-
ture).
• After the WAIT TO START light goes off, turn the
ignition key to START. Do not press the accelerator
during starting.
• After engine start-up, check to see that there is oil
pressure. • Allow the engine to idle about three minutes until
the manifold heaters have completed the post-heat
cycle.
• Release the parking brake and drive.
NOTE: Engine idle speed will automatically increase to
1000 rpm at low coolant temperatures to improve engine
warm-up.
NOTE: If the engine stalls or if the ignition switch is left
On for more than 2 minutes after the WAIT TO START
light goes out, reset the grid heaters by turning the
ignition switch to Off for at least 5 seconds and then back
On. Repeat steps 3 through 7 of the normal starting
procedure.
For Extremely Cold Weather Starting — Engine
Manifold Air Temperature Below 0°F (- 18°C)
In extremely cold weather below 0°F (- 18°C) it may be
beneficial to cycle the manifold heaters twice before254 STARTING AND OPERATING

cycle of the intake manifold heater system. The
number of cycles and the length of the cycling
operation is controlled by the engine control mod-
ule, this time will not exceed 150 seconds. The
needle should then stabilize at the approximate
operation point.
• The cycling action will cause temporary dimming of
the headlamps, interior lamps, and also a noticeable
reduction in blower motor speed.
Cold Weather Precautions
Operation in ambient temperature below 32°F (0°C) may
require special considerations. The following charts sug-
gest these options:
Fuel Operating Range
NOTE: Use “Ultra Low Sulfur Diesel Fuels” ONLY. *No. 1 Ultra Low Sulfur diesel fuel should only be used
where extended arctic conditions (-10°F/-23°C) exist.
NOTE:
• Use of Climatized Ultra Low Sulfur Diesel Fuel or
Number 1 Ultra Low Sulfur Diesel Fuel results in a
noticeable decrease in fuel economy.
• Climatized Ultra Low Sulfur Diesel Fuel is a blend of
Number 2 Ultra Low Sulfur and Number 1 Ultra Low
Sulfur Diesel Fuels which reduces the temperature at
which wax crystals form in fuel.258 STARTING AND OPERATING

Drive Belts (Gas Engines)
Belt tension is controlled by means of an automatic
tensioner. No belt tension adjustments are required.
However, belt and belt tensioner condition should be
inspected at the specified intervals and replaced if re-
quired. See your authorized dealer for service.
At the mileage indicated in the maintenance schedule, all
belts and tensioner should be checked for condition.
Improper belt tension can cause belt slippage and failure.
Belts should be inspected for evidence of cuts, cracks,
glazing or frayed cords and replaced if there is indication
of damage which could result in belt failure. Low gen-
erator belt tension can cause battery failure.
Also check belt routing to make sure there is no interfer-
ence between the belts and other engine components. Drive Belt (Diesel Engines)
Inspection
Check the belt for intersecting cracks.
• Transverse (across the belt width) cracks are accept-
able.
• Longitudinal (direction of belt length) cracks that
intersect with transverse cracks are NOT acceptable.
Replace the belt if it has unacceptable cracks, is frayed or
has pieces of material missing.
The engine speed sensor, located near the damper, should
be inspected for damage if a belt is frayed.
Engine Air Cleaner Filter (Gas Engines)
Under normal driving conditions, replace the air filter at
the intervals shown on Schedule “A”. If, however, you406 MAINTAINING YOUR VEHICLE
