1. Insert the first previously
programmedcoded keyinto the
ignition and turn the ignition from
the 1 (OFF/LOCK) position to the 3
(ON) position (maintain ignition in
the 3 (ON) position for at least one
second, but no more than ten
seconds).
2. Turn ignition from the 3 (ON)
position back to the 1 (OFF/LOCK)
position in order to remove the first
coded keyfrom the ignition.
3. Within ten seconds of removing the firstcoded key,insert the second
previously programmedcoded keyinto the ignition and turn the ignition
from the 1 (OFF/LOCK) position to the 3 (ON) position (maintain
ignition in the 3 (ON) position for at least one second but no more than
ten seconds).
4. Turn the ignition from the 3 (ON) position back to the 1 (OFF/LOCK)
position in order to remove the secondcoded keyfrom the ignition.
5. Within 10 seconds of removing the secondcoded key,insert the new
unprogrammed key (new key/valet key) into the ignition and turn the
ignition from the 1 (OFF/LOCK) position to the 3 (ON) position
(maintain ignition in the 3 (ON) position for at least one second, but no
more than ten seconds). This step will program your new key to a coded
key.
6. To program additional new unprogrammed key(s), repeat Steps 1
through 5.
If successful, the new coded key(s) will start the vehicle’s engine and the
theft indicator will illuminate for three seconds and then go out.
If not successful, the new coded key(s) will not start the vehicle’s engine
and the theft indicator will flash on and off and you may repeat Steps 1
through 5. If failure repeats, bring your vehicle to your authorized dealer
to have the new spare key(s) programmed.

Using the manual lumbar support
The lumbar support control is
located on the outboard side of the
seat
Turn the lumbar support clockwise
for more support.
Turn the lumbar support
counterclockwise for less support.
Heated seats (if equipped)
The heated seat control is located on the climate control panel.
Persons who are unable to feel pain to the skin because of
advanced age, chronic illness, diabetes, spinal cord injury,
medication, alcohol use, exhaustion, or other physical conditions, must
exercise care when using the seat heater. The seat heater may cause
burns even at low temperatures, especially if used for long periods of
time. Do not place anything on the seat that insulates against heat,
such as a blanket or cushion, because this may cause the seat heater
to overheat. Do not puncture the seat with pins, needles, or other
pointed objects because this may damage the heating element which
may cause the seat heater to overheat. An overheated seat may cause
serious personal injury.
Note:Do not do the following:
•Place heavy objects on the seat.
•Operate the seat heater if water or any other liquid is spilled on the
seat. Allow the seat to dry thoroughly.
To operate the heated seats, do the following (engine must be running):
Push
to activate; pushagain to deactivate.
The indicator light on the control will illuminate when activated.

Cargo Weight– includes all weight added to the Base Curb Weight,
including cargo and optional equipment. When towing, trailer tongue load
or king pin weight is also part of cargo weight.
GAW (Gross Axle Weight)– is the total weight placed on each axle
(front and rear) – including vehicle curb weight and all payload.
GAWR (Gross Axle Weight Rating)– is the maximum allowable
weight that can be carried by a single axle (front or rear).These
numbers are shown on the Safety Compliance Certification Label
located on the B-Pillar or the edge of the driver’s door. The total
load on each axle must never exceed its GAWR.
Exceeding the Safety Compliance Certification Label axle weight
rating limits could result in substandard vehicle handling or
performance, engine, transmission and/or structural damage, serious
damage to the vehicle, loss of control and personal injury.
Note:For trailer towing information refer toTrailer towingfound in
this chapter or theRV and Trailer Towing Guideprovided by your
authorized dealer.

The above calculations also assume that the loads are positioned in your
vehicle in a manner that does not overload the Front or the Rear Gross
Axle Weight Rating specified for your vehicle on the Tire Label or Safety
Compliance Certification Label found on the edge of the driver’s door.
Special loading instructions for owners of pickup trucks and
utility-type vehicles
For important information regarding safe operation of this type
of vehicle, see thePreparing to drive your vehiclesection in
theDrivingchapter of this owner guide.
Loaded vehicles may handle differently than unloaded vehicles.
Extra precautions, such as slower speeds and increased stopping
distance, should be taken when driving a heavily loaded vehicle.
Your vehicle can haul more cargo and people than most passenger cars.
Depending upon the type and placement of the load, hauling cargo and
people may raise the center of gravity of the vehicle.
TRAILER TOWING
Note:The trailer towing charts in this section apply to vehicles equipped
with gasoline engines; for vehicles equipped with diesel engines, refer to
your6.0 and 6.4 Liter Power Stroke Direct Injection Turbo Diesel
Owner’s Guide Supplement.
Your vehicle may tow a Conventional/Class IV trailer or fifth wheel trailer
provided the maximum trailer weight is less than or equal to the
maximum trailer weight listed for your engine and rear axle ratio on the
following charts.
To calculate your maximum trailer weight:
For pickup trucks:Take curb weight, hitch hardware and the driver’s
weight, then subtract them from the GCWR listed for your vehicle series,
engine, transmission and drive axle ratio(refer to the chart/table in the
following text). This calculation will give you the maximum trailer
weight possible for your vehicle.
For chassis cabs and pickup trucks with aftermarket equipment:
Weigh your vehicle at a certified scale and subtract this actual curb
weight, hitch hardware, and the driver’s weight from the GCWR listed for
your vehicle series, engine, transmission and drive axle ratio(refer to
the chart/table in the following text). This calculation will give you the
maximum trailer weight possible for your vehicle.

The weight of all additional cargo and passengers must be subtracted
from the maximum trailer weight calculated above.
Further trailer/hitch restrictions and limitations exist depending on the
type of trailer and hitch used. These additional maximum trailer weight
and tongue load limitations are listed in the chart/table that follows the
listing of GCWRs.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully prior to and after any towing operation. Refer to
Transmission fluid temperature gaugein theInstrument Cluster
chapter for the transmission fluid temperature information.
Note:Do not exceed the GCWR listed for your vehicle on the following
chart/table, or the GVWR, GAWR or tire ratings specified on the Tire
Label or Safety Compliance Certification Label.
Towing trailers beyond the maximum recommended trailer
weight which exceeds the limit of the vehicle’s GCWR, GVWR,
GAWR or tire ratings could result in engine damage, transmission
damage, structural damage, loss of vehicle control, vehicle rollover and
personal injury.
