• The lap portion should be low on the hips and as snug
as possible.
• Check belt fit periodically. A child’s squirming or
slouching can move the belt out of position.
If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm or behind
their back.
NEW ENGINE BREAK-IN
5.7L Gas Engine
A long break-in period is not required for the engine in
your new vehicle. Drive moderately during the first 300
miles (500 km). After the initial 60 miles (100 km), speeds
up to 50 or 55 mph (80 or 90 km/h) are desirable. While
cruising, brief full-throttle acceleration, within the limits of local traffic laws, contributes to a good break-in.
Avoid wide open throttle acceleration in low gear.
The engine oil installed in the engine at the factory is a
high quality, energy conserving type lubricant. Oil
changes should be consistent with the anticipated cli-
matic conditions under which vehicle operation will
occur. The recommended viscosity and quality grades are
discussed in Section 7 under Maintenance Procedures,
Engine Oil.
NON-DETERGENT OR STRAIGHT MINERAL OILS
MUST NEVER BE USED.
A new engine may consume some oil during its first few
thousand miles of operation. This is a normal part of the
break-in and is not an indication of difficulty.72 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

CAUTION!• During the first 500 miles (805 km) your new
vehicle is driven, do not tow a trailer. Doing so
may damage your axles, driveline and vehicle.
• Limit your speed to 50 mph (80 km/h) during the
first 500 miles (805 km) of towing.
6.7L Diesel Engine
Your Cummins 24 Valve Turbo Diesel engine does not
require a break-in period due to its construction. Normal
operation is allowed, provided the following recommen-
dations are followed:
NOTE: Light duty operation such as light trailer towing
or no load operation, will extend the time before the
engine is at full efficiency and may effect the performance
of the vehicle aftertreatment (exhaust) system. Reduced
fuel economy and power may be seen at this time. • Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged
periods.
• Use the appropriate transmission gear to prevent
engine lugging.
• Observe vehicle oil pressure and temperature indica-
tors.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carry-
ing or towing significant weight.
Because of the construction of the Cummins Diesel
engine, engine run-in is enhanced by loaded operating
conditions which allow the engine parts to achieve final
finish and fit during the first 6,000 miles (10 000 km). THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 73

Exhaust Gas
WARNING!Exhaust gases contain carbon monoxide, a poten-
tially toxic gas that by itself is colorless and odorless.
To avoid inhaling these gases, the following precau-
tions should be observed:
• Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in
or out of the area.
• If it is necessary to sit in a parked vehicle with the
engine running for more than a short period, adjust
your climate control system to force outside air into the vehicle. Set the blower at high speed and the
controls in any position except OFF or MAX A/C.
• The best protection against carbon monoxide entry
into the vehicle body is a properly maintained engine
exhaust system.
Be aware of changes in the sound of the exhaust system;
exhaust fumes detected inside the vehicle; or damage to
the underside or rear of the vehicle. Have a competent
mechanic inspect the complete exhaust system and adja-
cent body areas for broken, damaged, deteriorated or
mispositioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust system
each time the vehicle is raised for lubrication or oil
change. Replace or adjust as required. THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 75

Things You Should Know About Your UConnect™
System
Voice Training
For users experiencing difficulty with the system recog-
nizing their voice commands or numbers, the UConnect
system Voice Training feature may be used. To enter this training mode, follow one of the two procedures: From
outside the UConnect mode (e.g. from radio mode),
• Press and hold the ‘Voice Recognition’ button for 5
seconds until the session begins, or
• Press the ‘Voice Recognition’ button and say Setup,
Voice Training command.
Repeat the words and phrases when prompted by the
UConnect System. For best results, the Voice Training
session should be completed when the vehicle is parked,
engine running, all windows closed, and the blower fan
switched off.
This procedure may be repeated with a new user. The
system will adapt to the last trained voice only.
To restore the Voice recognition system to factory default
settings, enter the Voice Training session via the above
procedure and follow the prompts. UNDERSTANDING THE FEATURES OF YOUR VEHICLE 105

Headlights, Parking Lights, Panel Lights
When the headlight switch is rotated to the first
position, the parking lights, taillights, side marker
lights, license plate light and instrument panel
lights are all turned on. The headlights will turn ON
when the switch is rotated to the second position. Your vehicle is equipped with plastic headlight lenses
that are lighter and less susceptible to stone breakage
than glass headlights.
Plastic is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed.
To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution fol-
lowed by rinsing.
Do not use abrasive cleaning components, solvents, steel
wool or other abrasive materials to clean the lenses.
Daytime Running Lights (Canada Only and Fleet
Vehicles)
The headlights on your vehicle will illuminate when the
engine is started an the transmission is in any gear except
park. This provides a constant Lights ON condition
until the ignition is turned OFF. The lights illuminate atLight Switch Rotation124 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

RESET button approximately five seconds. The last vari-
ance zone number will be displayed. Press the STEP
button to select the new variance zone and press the
RESET button to resume normal operation.
Outside Temperature
Because the ambient temperature sensor is located un-
derhood, engine temperature can influence the displayed
temperature, therefore, temperature readings are slowly
updated when the vehicle speed is below 20 mph (30
km/h) or during stop and go driving. OVERHEAD CONSOLE WITH ELECTRONIC
VEHICLE INFORMATION CENTER (EVIC) —
DIESEL ONLY
The overhead console contains dome/reading lights, and

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
