System Limitations
WARNING
The collision warning system’s
brake support can only help
reduce the speed at which a collision
occurs if the driver applies the
vehicle’s brakes. The brake pedal
must be pressed just like any typical
braking situation.
Due to the nature of radar technology,
there may be certain instances where
vehicles do not provide a collision
warning. These include: • Stationary vehicles or vehicles
moving below 6 mph (10 km/h).
• Pedestrians or objects in the roadway.
• Oncoming vehicles in the same lane.
• Severe weather conditions (see blocked sensor section).
• Debris build-up on the grille near the headlamps (see blocked
sensor section).
• Small distance to vehicle ahead.
• Steering wheel and pedal movements are large (very active
driving style).

Driving Aids

If the front end of the vehicle is hit or
damaged, the radar sensing zone may
be altered causing missed or false
collision warnings. See your
authorized dealer to have your
collision warning radar checked for
proper coverage and operation.
STEERING
Electric Power Steering
WARNINGS
The electric power steering
system has diagnostic checks
that continuously monitor the system
to ensure proper operation. When a
system error is detected a steering
message will appear in the
information display.
The electric power steering
system has diagnostic checks
that continuously monitor the system
to ensure proper operation of the
electronic system. When an electronic
error is detected, a message will be
displayed in the information display.
If this happens, stop the vehicle in a
safe place, and turn off the engine.
After at least 10 seconds, reset the
system by restarting the engine, and
watch the information display for a
steering message. If a steering
message returns, or returns while
driving, take the vehicle to your dealer
to have it checked.
WARNINGS
Obtain immediate service if a
system error is detected. You
may not notice any difference in the
feel of your steering, but a serious
condition may exist. Failure to do so
may result in loss of steering control.
Your vehicle is equipped with an
electric power-assisted steering
system. There is no fluid reservoir to
check or fill.
If your vehicle loses electrical power
while you are driving (or if the ignition
is turned off), you can steer the
vehicle manually, but it takes more
effort. Extreme continuous steering
may increase the effort it takes for you
to steer. This occurs to prevent
internal overheating and permanent
damage to your steering system. If this
should occur, you will neither lose the
ability to steer the vehicle manually
nor will it cause permanent damage.
Typical steering and driving
maneuvers will allow the system to
cool and steering assist will return to
normal.
Steering Tips
If the steering wanders or pulls, check
for:
• an improperly inflated tire
• uneven tire wear
• loose or worn suspension components
• loose or worn steering components
• improper vehicle alignment

WARNING
The appropriate loading
capacity of your vehicle can
be limited either by volume
capacity (how much space is
available) or by payload capacity
(how much weight the vehicle
should carry). Once you have
reached the maximum payload of
your vehicle, do not add more
cargo, even if there is space
available. Overloading or
improperly loading your vehicle
can contribute to loss of vehicle
control and vehicle rollover.

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.
E143819
GCW GVW
GCW (Gross Combined Weight)
- is the Gross Vehicle Weight 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
228
Load Carrying

for operation at Gross Vehicle
Weight Rating, not at Gross
Combined Weight Rating.)
Separate functional brakes should
be used for safe control of towed
vehicles and for trailers where the
Gross Combined Weight of the
towing vehicle plus the trailer
exceed the Gross Vehicle Weight
Rating of the towing vehicle.The
Gross Combined Weight must
never exceed the Gross
Combined Weight Rating.
Maximum Loaded Trailer
Weight - is the highest possible
weight of a fully loaded trailer the
vehicle can tow. It assumes a
vehicle with mandatory options,
driver and front passenger weight
(150 pounds [68 kilograms]
each), no cargo weight (internal
or external) and a tongue load of
10–15% (conventional trailer) or
king pin weight of 15–25% (fifth
wheel trailer). Consult an
authorized dealer (or the RV and
Trailer Towing Guide available at
an 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 5000 pound
(2268 kilogram) conventional
trailer, multiply 5000 by 0.10 and
0.15 to obtain a proper tongue
load range of 500 to 750 pounds
(227 to 340 kilograms). For an
11500 pound (5216 kilogram) fifth
wheel trailer, multiply by 0.15 and
0.25 to obtain a proper king pin
load range of 1725 to 2875 pounds
(782 to 1304 kilograms).
WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
Safety Compliance Certification
Label.
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.
Exceeding any vehicle weight
rating limitation could result
in serious damage to the vehicle
and/or personal injury.
Steps for determining the
correct load limit:
1. Locate the statement "The combined weight of occupants
and cargo should never exceed
XXX kg or XXX lb." on your
vehicle’s placard.

Load Carrying

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
certification label.
Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of your vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of vehicle control,
vehicle rollover and personal
injury.
Note: There may be electrical
items such as fuses or relays that
can affect trailer towing operation.
See Fuses (page 255).
Weight, not volume designates
your vehicle's load capacity. 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 periodically
during, and after, any towing
operation. Load Placement
To help minimize how trailer
movement affects the vehicle
when driving:
• Load the heaviest items closest
to the trailer floor.
• Load the heaviest items in the center of the left and right side
trailer tires.
• Load the heaviest items above the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
• Select a tow bar with the correct rise or drop. When both
the loaded vehicle and trailer
are connected, the trailer frame
should be level, or slightly
angled down toward the
vehicle, when viewed from the
side.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in the Load Carrying
chapter. See Load Limit (page
224). You can also find the
information in the RV & Trailer
Towing Guide, available at an
authorized dealer.

ESSENTIAL TOWING
CHECKS
Follow these guidelines for safe
towing:
• Do not tow a trailer until you driveyour vehicle at least 1000 miles
(1600 kilometers).
• Consult your local motor vehicle laws for towing a trailer.
• See the instructions included with towing accessories for the proper
installation and adjustment
specifications.
• Service your vehicle more frequently if you tow a trailer. See
your scheduled maintenance
information.
• If you use a rental trailer, follow the instructions the rental agency gives
you.
You can find information on load
specification terms found on the tire
label and Safety Compliance label as
well as instructions on calculating
your vehicle's load in the Load
Carrying chapter. See Load Limit
(page 224).
Remember to account for the trailer
tongue weight as part of your vehicle
load when calculating the total
vehicle weight.
Hitches
Do not use a hitch that either clamps
onto the bumper or attaches to the
axle. Distribute the trailer load so 10-15%
of the total trailer weight is on the
tongue.
Safety Chains
Note:
Never attach safety chains to
the bumper.
Always connect the safety chains to
the hook retainers of your vehicle
hitch.
To connect the safety chains, cross
them under the trailer tongue and
allow enough slack for turning tight
corners. Do not allow the chains to
drag on the ground.
Trailer Brakes
WARNING
Do not connect a trailer's
hydraulic brake system directly
to your vehicle's brake system. Your
vehicle may not have enough braking
power and your chances of having a
collision greatly increase.
Electric brakes and manual,
automatic or surge-type trailer brakes
are safe if you install them properly
and adjust them to the
manufacturer's specifications. The
trailer brakes must meet local and
federal regulations.
The rating for the tow vehicle's
braking system operation is at the
gross vehicle weight rating, not the
gross combined weight rating.

Towing

Trailer Lamps
WARNING
Never connect any trailer lamp
wiring to the vehicle's tail lamp
wiring; this may damage the electrical
system resulting in fire. Contact your
authorized dealer as soon as possible
for assistance in proper trailer tow
wiring installation. Additional
electrical equipment may be required.
Trailer lamps are required on most
towed vehicles. Make sure all running
lights, brake lights, turn signals and
hazard lights are working.
Before Towing a Trailer
Practice turning, stopping and backing
up to get the feel of your
vehicle-trailer combination before
starting on a trip. When turning, make
wider turns so the trailer wheels clear
curbs and other obstacles.
When Towing a Trailer
• Do not drive faster than 70 mph (113 km/h) during the first 500
miles (800 kilometers).
• Do not make full-throttle starts.
• Check your hitch, electrical connections and trailer wheel lug
nuts thoroughly after you have
traveled 50 miles (80 kilometers).
• When stopped in congested or heavy traffic during hot weather,
place the gearshift in position P to
aid engine and transmission
cooling and to help A/C
performance. • Turn off the speed control with
heavy loads or in hilly terrain. The
speed control may turn off
automatically when you are towing
on long, steep grades.
• Shift to a lower gear when driving down a long or steep hill. Do not
apply the brakes continuously, as
they may overheat and become
less effective.
• If your transmission is equipped with a Grade Assist or Tow/Haul
feature, use this feature when
towing. This provides engine
braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping with a trailer attached. Anticipate
stops and brake gradually.
• Avoid parking on a grade. However, if you must park on a grade:
• Turn the steering wheel to pointyour vehicle tires away from
traffic flow.
• Set your vehicle parking brake.
• Place the automatic transmission in position P.
• Place wheel chocks in front and back of the trailer wheels.
(Chocks not included with
vehicle.)
Launching or Retrieving a Boat
or Personal Watercraft (PWC)
Note: Disconnect the wiring to the
trailer before backing the trailer into
the water.
