When inflating your tires

When putting air into your tires (such as at a gas station or in your
garage), the Tire Pressure Monitoring System may not respond
immediately to the air added to your tires.

It may take up to two minutes of driving over 20 mph (32 km/h) for the
light to turn OFF after you have filled your tires to the recommended
tire pressure.

How temperature affects your tire pressure

The Tire Pressure Monitoring System (TPMS) monitors tire pressure in
each pneumatic tire. While driving in a normal manner, a typical
passenger tire inflation pressure may increase approximately 2 to 4 psi
(14 to 28 kPa) from a cold start situation. If the vehicle is stationary
over night with the outside temperature significantly lower than the
daytime temperature, the tire pressure may decrease approximately 3 psi
(20.7 kPa) for a drop of 30° F (16.6° C) in ambient temperature. This
lower pressure value may be detected by the TPMS as being lower than
the recommended inflation pressure and activate the TPMS warning for
low tire pressure. If the low tire pressure warning light is ON, visually
check each tire to verify that no tire is flat. If one or more tires are flat,
repair as necessary. Check air pressure in the road tires. If any tire is

underinflated, carefully drive the vehicle to the nearest location where
air can be added to the tires. Inflate all the tires to the recommended
inflation pressure.

SNOW TIRES AND CHAINS

WARNING: Driving too fast for conditions creates the
possibility of loss of vehicle control. Driving at very high speeds
for extended periods of time may result in damage to vehicle
components.

NOTE: Snow tires must be the same size and grade as the tires you
currently have on your vehicle.

The tires on your vehicle have all weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains. If you need to use snow tires and chains, it is
recommended that steel wheels are used of the same size and
specifications as those originally installed.

Follow these guidelines when using snow tires and chains:
• Do not use tire chains on aluminum wheels. Chains may chip the

wheels.

• Use only SAE Class S chains.
• Install chains securely, verifying that the chains do not touch any

wiring, brake lines or fuel lines.

Drive cautiously. Ensure you obtain the proper cables or chains
for you vehicle. Test fit the cables or chains before using them in
snow and/or ice. If you hear the cables or chains rub or bang
against the vehicle, stop and retighten them. If this does not
work, remove the cables or chains to prevent vehicle damage.
Have the cables or chains fitted by a professional before
proceeding.
• If possible, avoid fully loading your vehicle.
• Remove the tire chains when they are no longer needed. Do not use

tire chains on dry roads.

• The suspension insulation and bumpers will help prevent vehicle

damage. Do not remove these components from your vehicle when
using snow tires and chains.

VEHICLE LOADING – WITH AND WITHOUT A TRAILER

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
Tire Label or Safety Compliance Certification 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 authorized dealer plus any aftermarket
equipment.

Tires, Wheels and Loading

136

Payload – is the combined weight of cargo and passengers that the
vehicle is carrying. The maximum payload for your vehicle can be found
on the Tire Label on the B-Pillar or the edge of the driver’s door
(vehicles exported outside the US and Canada may not have a Tire
Label). Look for “THE COMBINED WEIGHT OF OCCUPANTS AND
CARGO SHOULD NEVER EXCEED XXX kg OR XXX lb.” for
maximum payload. The payload listed on the Tire Label is the maximum
payload for the vehicle as built by the assembly plant. If any aftermarket
or authorized-dealer installed equipment has been installed on the
vehicle, the weight of the equipment must be subtracted from the
payload listed on the Tire Label in order to determine the new payload.

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.

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.

Note: For trailer towing information refer to Trailer towing found in
this chapter or the RV and Trailer Towing Guide provided by your
authorized dealer.

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 B-Pillar or
the edge of the driver’s door.
The GVW must never exceed the
GVWR.

WARNING: Exceeding the Safety Compliance 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 lb. [68 kg]). Consult your authorized
dealer (or the RV and Trailer Towing Guide provided 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 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.

WARNING: 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 lbs.” on your vehicle’s placard.

2. Determine the combined weight of the driver and passengers that

will be riding in your vehicle.

3. Subtract the combined weight of the driver and passengers from

XXX kg or XXX lbs.

4. The resulting figure equals the available amount of cargo and

luggage load capacity. For example, if the “XXX” amount equals
1,400 lbs. and there will be five 150 lb. passengers in your vehicle,
the amount of available cargo and luggage load capacity is 650 lbs.
(1400-750 (5 x 150) = 650 lb.). In metric units (635-340 (5 x 68) =
295 kg.)

5. Determine the combined weight of luggage and cargo being loaded

on the vehicle. That weight may not safely exceed the available
cargo and luggage load capacity calculated in Step 4.

6. If your vehicle will be towing a trailer, load from your trailer will be

transferred to your vehicle. Consult this manual to determine how
this reduces the available cargo and luggage load capacity of your
vehicle.

The following gives you a few examples on how to calculate the available
amount of cargo and luggage load capacity:
• Another example for your vehicle with 1400 lb. (635 kg) of cargo and

luggage capacity. You decide to go golfing. Is there enough load
capacity to carry you, 4 of your friends and all the golf bags? You and
four friends average 220 lb. (99 kg) each and the golf bags weigh
approximately 30 lb. (13.5 kg) each. The calculation would be: 1400 -
(5 x 220) - (5 x 30) = 1400 - 1100 - 150 = 150 lb. Yes, you have
enough load capacity in your vehicle to transport four friends and
your golf bags. In metric units, the calculation would be: 635 kg - (5 x
99 kg) - (5 x 13.5 kg) = 635 - 495 - 67.5 = 72.5 kg.

• A final example for your vehicle with 1400 lb. (635 kg) of cargo and

luggage capacity. You and one of your friends decide to pick up
cement from the local home improvement store to finish that patio

you have been planning for the past 2 years. Measuring the inside of
the vehicle with the rear seat folded down, you have room for 12-100
lb. (45 kg) bags of cement. Do you have enough load capacity to
transport the cement to your home? If you and your friend each weigh
220 lb. (99 kg), the calculation would be: 1400 - (2 x 220) - (12 x
100) = 1400 - 440 - 1200 = - 240 lb. No, you do not have enough
cargo capacity to carry that much weight. In metric units, the
calculation would be: 635 kg - (2 x 99 kg) - (12 x 45 kg) = 635 - 198 -
540 = -103 kg. You will need to reduce the load weight by at least 240
lb. (104 kg). If you remove 3-100 lb. (45 kg) cement bags, then the
load calculation would be:

1400 - (2 x 220) - (9 x 100) = 1400 - 440 - 900 = 60 lb. Now you have
the load capacity to transport the cement and your friend home. In
metric units, the calculation would be: 635 kg - (2 x 99 kg) - (9 x 45
kg) = 635 - 198 - 405 = 32 kg.

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 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

WARNING: For important information regarding safe operation
of this type of vehicle, see the Preparing to drive your vehicle
section in the Driving chapter of this Owner’s Guide.

WARNING: 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

Your vehicle may tow a class I, II or III 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.

Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.

WARNING: Do not exceed the GVWR or the GAWR specified on
the certification label.

The certification label is found on the driver’s door latch pillar.

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.

Preparing to tow

Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your authorized dealer or a
reliable trailer dealer if you require assistance.

Hitches

For towing trailers up to 2,000 lb. (907 kg), use a weight carrying hitch
and ball which uniformly distributes the trailer tongue loads through the

Do not install a single or multi-clamp type bumper hitch, or a hitch
which attaches to the axle. Underbody mounted hitches are acceptable if
they are installed properly. Follow the towing instructions of a reputable
rental agency.

Whenever a trailer hitch and hardware are removed, make sure all
mounting holes in the underbody are properly sealed to prevent noxious
gases or water from entering.

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.

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.

The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.

Trailer lamps

Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. See your
authorized dealer or trailer rental agency for proper instructions and
equipment for hooking up trailer lamps.

Using a step bumper

The optional step bumper is equipped with an integral hitch and requires
only a ball with a 3/4 inch (19 mm) shank diameter. The bumper has a
2,000 lb. (907 kg) trailer weight and 200 lb. (91 kg) tongue weight
capability.
