SAFETY AND ENVIRONMENT PROTECTION
Warning symbols in this guide
How can you reduce the risk of personal injury to yourself or others? In
this guide, answers to such questions are contained in comments
highlighted by the warning triangle symbol. These comments should be
read and observed.
Warning symbols on your vehicle
When you see this symbol, it is
imperative that you consult the
relevant section of this guide before
touching or attempting adjustment
of any kind.
Protecting the environment
We must all play our part in
protecting the environment. Correct
vehicle usage and the authorized
disposal of waste, cleaning and
lubrication materials are significant
steps towards this aim. Information in this respect is highlighted in this
guide with the tree symbol.
BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles (1,600 km) of
new vehicle operation. Vary your speed frequently in order to give the
moving parts a chance to break in.
Drive your new vehicle at least 500 miles (800 km) before towing a
trailer.
Do not add friction modifier compounds or special break-in oils during
the first few thousand miles (kilometers) of operation, since these
additives may prevent piston ring seating. SeeEngine oilin the
Maintenance and Specificationschapter for more information on oil
usage.

This system is not designed to prevent contact with small or
moving objects. The system is designed to provide a warning to
assist the driver in detecting objects to avoid damaging the vehicle.
The system may not detect smaller objects, particularly those close to
the ground.
Certain add-on devices such as large trailer hitches, bike or
surfboard racks and any device that may block the normal
detection zone of the extended rear park aid system may create false
beeps.
The system will assist the driver in detecting certain objects while the
vehicle slowly moves in reverse at speeds less than 6 mph (10 km/h).
The system is not effective at speeds greater than 6 mph (10 km/h) and
may not detect certain angular or moving objects.
The system detects obstacles within approximately 16 feet (five meters),
at speeds above 2 mph [3 km/h]) behind the rear bumper with a
decreased coverage area at the outer corners of the bumper. If vehicle
speed is below 2 mph (3 km/h), the system detects obstacles within
approximately 10 feet (three meters) behind the rear bumper with a
decreased coverage area at the outer corners of the bumper. In the
figure, the smaller objects behind the vehicle represent the near-vehicle
and bumper corner coverage area of the park aid system and the large
object represents the extended coverage area. As you move closer to the
obstacle, the rate of the tone increases. When the distance to the
obstacle is less than 18 inches (45.0 cm), the tone will sound
continuously. If the system detects an object that is approaching the
vehicle at such as rate that rapid braking is required, a very high rate
tone will sound. If this tone is heard while reversing, the driver is
advised to slow down immediately until the tone either changes to a
slower rate or stops. While receiving a warning the radio volume will be
reduced to a predetermined level. After the warning goes away, the radio
will return to the previous volume. The radio volume may be overridden
using the radio volume control.

VEHICLE LOADING–WITH AND WITHOUT A TRAILER
This section will guide you in the proper loading of your vehicle and/or
trailer, to keep your loaded vehicle weight within its design rating
capability, with or without a trailer. Properly loading your vehicle will
provide maximum return of vehicle design performance. Before loading
your vehicle, familiarize yourself with the following terms for determining
your vehicle’s weight ratings, with or without a trailer, from the vehicle’s
Safety Certification Label and Tire Label:
Base Curb Weight–is the weight of the vehicle including a full tank of
fuel and all standard equipment. It does not include passengers, cargo, or
optional equipment.
Vehicle Curb Weight–is the weight of your new vehicle when you
picked it up from your dealer plus any aftermarket equipment.
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 driver’s door or B-Pillar. The total load on each
axle must never exceed its GAWR.
Exceeding the Safety 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
dealership.
GVW (Gross Vehicle Weight)–is the Vehicle Curb Weight + cargo +
passengers.
GVWR (Gross Vehicle Weight
Rating)–is the maximum
allowable weight of the fully loaded
vehicle (including all options,
equipment, passengers and cargo).
The GVWR is shown on the
Safety Compliance Certification
Label located on the driver’s
door or B-Pillar. The GVW must
never exceed the GVWR.
Exceeding the Safety Certification Label vehicle 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.

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 lbs [68 kg]).Consult your dealership (or
theRV and Trailer Towing Guideprovided by your dealership) 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 lbs. (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 lbs. (227 to 340 kg). For an 11,500 lbs. (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 lbs. (782 to 1,304 kg)
Do not exceed the GVWR or the GAWR specified on the
certification label.
Do not use replacement tires with lower load carrying capacities
than the originals because they may lower the vehicle’s GVWR
and GAWR limitations. Replacement tires with a higher limit than the
originals do not increase the GVWR and GAWR limitations.

Exceeding any vehicle weight rating limitation could result in
serious damage to the vehicle and/or personal injury.
TRAILER TOWING
Your vehicle is classified as a light duty towing vehicle. Do not tow a
trailer until your vehicle has been driven at least 2,000 miles (3,200 km).
Towing a trailer places an additional load on your vehicle’s engine,
transmission, brakes, tires and suspension. Inspect these components
carefully after towing.
Your loaded trailer should weigh no more than 2,000 lbs. (907 kg).Do
not exceed the GVWR specified on the certification label.
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.
The GCW of your vehicle and trailer should not exceed 6,600 lbs. (2,993 kg).
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
Hitches
Do not use hitches that clamp onto the vehicle bumper. Use a load
carrying hitch. You must distribute the load in your trailer so that
10–15% of the total weight of the trailer is on the tongue.
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.
