WARNING:Do not use the speed control in heavy traffic or on
roads that are winding, slippery or unpaved.
Using speed controls
The speed controls are located on the steering wheel. The following
buttons work with speed control:
– SET +:Press to set a speed or to
increase or decrease the set speed.
CNCL (Cancel)/RSM (Resume):
Press to return cancel or resume a
set speed.
ON/OFF:Press to turn speed
control on or off.
The speed control system uses two
indicator lights in the
instrument cluster:
•an amber indicator light which illuminates when the system is on, and
•a green indicator light which illuminates when the system is engaged.
Setting speed control
To set speed control:
1. Press and release ON.
2. Accelerate to the desired speed.
3. Press and release SET +.
4. Take your foot off the accelerator pedal.
5. The green indicator
light on the instrument cluster will turn on.
Note:
•Vehicle speed may vary momentarily when driving up and down a
steep hill.
•If the vehicle speed increases above the set speed on a downhill, you
may want to apply the brakes to reduce the speed.
•If the vehicle speed decreases more than 10 mph (16 km/h) below
your set speed on an uphill, your speed control will disengage.

Safety belt systems equipped with an energy management retractor must
be replaced if they were in use during a frontal collision which resulted
in deployment of the frontal airbags. Refer to theSafety belt
maintenancesection in this chapter.
Safety belt locking modes
All safety restraints in the vehicle are combination lap and shoulder
belts. The driver safety belt and the optional front center seat’s safety
belt have the first locking mode only. All outboard passenger and rear
safety belts have both types of locking modes described as follows:
Vehicle sensitive mode
This is the normal retractor mode, which allows free shoulder belt length
adjustment to your movements and locking in response to vehicle
movement. For example, if the driver brakes suddenly or turns a corner
sharply, or the vehicle receives an impact of approximately 5 mph
(8 km/h) or more, the combination safety belts will lock to help reduce
forward movement of the driver and passengers.
In addition, the retractor is designed to lock if the webbing is pulled out
too quickly. If this occurs, let the belt retract slightly and pull webbing
out again in a slow and controlled manner.
Automatic locking mode
In this mode, the shoulder belt is automatically pre-locked. The belt will
still retract to remove any slack in the shoulder belt. The automatic
locking mode is not available on the driver safety belt or the optional
front seat’s center safety belt.
When to use the automatic locking mode
This mode should be usedany timea child safety seat is installed in a
front outboard passenger seating position in a Regular Cab / SuperCab /
SuperCrew or any rear seating position of a SuperCab or SuperCrew. The
optional front seat’s center safety belt has a cinch mechanism. Refer to
Safety belt with cinch tongue earlier in this chapter. Children 12 years
old and under should be properly restrained in a rear seat whenever
possible. Refer toSafety restraints for childrenorSafety seats for
childrenlater in this chapter.

GCW (Gross Combined Weight)– is the weight of the loaded vehicle
(GVW) plus the weight of the fully loaded trailer.
GCWR (Gross Combined Weight Rating)– is the maximum allowable
weight of the vehicle and the loaded trailer – including all cargo and
passengers – that the vehicle can handle without risking damage.
(Important: The towing vehicle’s braking system is rated for operation at
GVWR, not at GCWR.) Separate functional brakes should be used for
safe control of towed vehicles and for trailers where the GCW of the
towing vehicle plus the trailer exceed the GVWR of the towing vehicle.
The GCW must never exceed the GCWR.
Maximum Loaded Trailer Weight– is the highest possible weight of a
fully loaded trailer the vehicle can tow. It assumes a vehicle with only
mandatory options, no cargo (internal or external), a tongue load of
10–15% (conventional trailer) or king pin weight of 15–25% (fifth wheel
trailer), and driver only (150 lb. [68 kg]).Consult your authorized
dealer (or theRV and Trailer Towing Guideprovided by your
authorized dealer) for more detailed information.
Tongue Load or Fifth Wheel King Pin Weight– refers to the amount
of the weight that a trailer pushes down on a trailer hitch.
Examples:For a 5,000 lb. (2,268 kg) conventional trailer, multiply 5,000
by 0.10 and 0.15 to obtain a proper tongue load range of 500 to 750 lb.
(227 to 340 kg). For an 11,500 lb. (5,216 kg) fifth wheel trailer, multiply
by 0.15 and 0.25 to obtain a proper king pin load range of 1,725 to
2,875 lb. (782 to 1,304 kg)
WARNING:Do not exceed the GVWR or the GAWR specified on
the Safety Compliance Certification Label.
WARNING:Do not use replacement tires with lower load
carrying capacities than the original tires because they may
lower the vehicle’s GVWR and GAWR limitations. Replacement tires
with a higher limit than the original tires do not increase the GVWR
and GAWR limitations.

Note:Do not exceed trailer weight of 5,000 lb (2,268 kg) when towing
with bumper only.
Exceeding the maximum GCWR could result in extensive damage
to your vehicle and personal injury.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully periodically during, and after any towing operation.
Follow these guidelines to ensure safe towing:
•Do not tow a trailer until your vehicle has been driven at least
1,000 miles (1,600 km).
•Consult your local motor vehicle laws for towing a trailer.
•Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.
•Thoroughly prepare your vehicle for towing. Refer toPreparing to
towin this chapter.
•Stay within your vehicle’s load limits.
•Use extra caution when driving while trailer towing. Refer toDriving
while you towin this chapter.
•Service your vehicle more frequently if you tow a trailer. Refer to
Special operating conditionsin theScheduled Maintenance Guide
chapter.
For load specification terms found on the label and instructions on
calculating your vehicle’s load, refer toVehicle loading - with and
without a trailerin this chapter. Remember to figure in the tongue load
of your loaded vehicle when figuring the total weight.
WARNING:Do not exceed the GVWR or the GAWR specified on
the certification label.
WARNING:Towing trailers beyond the maximum recommended
gross trailer weight exceeds the limit of the vehicle and could
result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.

Weight-distributing hitch
When hooking-up a trailer using a weight-distributing hitch, always use
the following procedure:
1. Park the vehicle (without the trailer) on a level surface.
2. Measure the height of the top of the front wheel opening on the
fender, this is H1.
3. Attach the trailer to the vehicle without the weight distributing bars
connected.
4. Measure the height of the top of the front wheel opening on the
fender a second time, this is H2.
5. Install and adjust the tension in the weight distributing bars so that
the height of the front fender is approximately halfway between H1 and
H2.
6. Check that the trailer is level. If not level, adjust the ball height
accordingly and repeat Steps 3–6.
WARNING:Do not adjust a weight-distributing hitch to any
position where the rear bumper of the vehicle is higher than it
was before attaching the trailer. Doing so will defeat the function of
the weight-distributing hitch, which may cause unpredictable handling,
and could result in serious personal injury.
Safety chains
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle hitch. To connect the trailer’s safety chains, cross the
chains under the trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.
