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 toTrailer towingfound in
this chapter or theRV and Trailer Towing Guideprovided 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.
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 vehicles’ 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.
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 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.
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:
2007 Monterey(mty)
Owners Guide (post-2002-fmt)
USA(fus)
Tires, Wheels and Loading
202

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.
TRAILER TOWING
Your vehicle is capable either of towing Class I trailers or up to Class II
trailers when equipped with the optional trailer tow package.
If your vehicle does not have the optional trailer tow package your
vehicle is partially prepped for trailer tow lamp wiring but you will also
need to install electrical kit (15A416). This kit contains fuses and relays
to isolate the vehicle lighting circuitry from the trailer lighting and an
adapter wiring harness containing the standard 4-pin trailer plug. Refer
to theTrailer lampssection in this chapter for additional information.
Do not tow above 2,000 lb. (907 kg) without the
manufacturer-installed trailer tow package.
A new underbody wiring harness (14406) will be a component to this kit
and will need to be installed, if applicable, per instructions located in the
service kit.
If your vehicle has the optional trailer tow package it comes with heavy
duty cooling fans, auxiliary transmission fluid cooler, an auxiliary engine
oil cooler, heavy duty battery, trailer tow wiring (including fuses and
relays to isolate the vehicle lighting circuitry from the trailer lighting)
and a kit (in a cardboard box) that includes an adapter wiring harness
that contains the standard 4-pin trailer plug.
Trailer towing puts additional loads on your vehicle’s engine,
transmission, axle, brakes, tires, and suspension. For your safety and to
maximize vehicle performance, be sure to use the proper equipment
while towing.
Follow these guidelines to ensure safe towing procedure:
•Stay within your vehicle’s load limits. If exceeded, cargo should be
removed from the trailer and/or the vehicle until all weights are within
specified limits.
•Thoroughly prepare your vehicle for towing. Refer toPreparing to
towin this chapter.

•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 the scheduled maintenance
information.
•Do not tow a trailer until your vehicle has been driven at least
500 miles (800 km).
•Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.

Do not exceed the maximum loads listed on the Safety Compliance
Certification label. For load specification terms found on the label, refer
toVehicle loadingin this chapter. Remember to figure in the tongue
load of your loaded trailer when figuring the total weight.
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 control
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
Do not use hitches that clamp onto the vehicle bumper. Use a load
carrying hitch that does not exceed your vehicle’s capability. See the
Tongue Loadsection in the trailer towing chart earlier in this section for
range details on a specific trailer load.
Safety chains
Always connect the trailer’s safety chains to the hook retainers on the
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
Be sure your trailer conforms to all applicable local and Federal
Regulations regarding trailer braking. If your trailer is equipped with
electronically controlled brakes you will need to have an electronic brake
controller with associated wiring installed to your vehicle by an
authorized dealer.
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.
Do not splice into the vehicle lamp wiring for trailer lamps. Your
vehicle uses an advanced electronic module to control and
monitor your vehicle lamps. Splicing into the wiring or attaching
wiring to the vehicle bulb. may DISABLE the rear vehicle lamps
or cause them not to function properly. Your lamp outage feature
may also be disabled or provide incorrect information.
See your authorized dealer or trailer rental agency for proper
instructions and equipment for hooking up trailer lamps.

Driving while you tow
When towing a trailer:
•Keep your speed no faster than 70 mph (112 km/h) during the first
500 miles (800 km) of towing a trailer, and don’t make full throttle
starts.
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Consult your local motor vehicle speed regulations for towing a trailer.
•To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to
Understanding the gearshift positions of the 4–speed automatic
transmissionin theDriving chapter.
•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourScheduled Maintenance
Informationfor more information.
Trailer towing tips
•Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•Allow more distance for stopping with a trailer attached.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to theMaintenance and Specificationschapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 500 miles (800 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (112 km/h) with no full throttle starts.

•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
RECREATIONAL TOWING
Follow these guidelines for your specific powertrain combination to tow
your vehicle with all four wheels on the ground (such as behind a
recreational vehicle).
These guidelines are designed to ensure that your transmission is not
damaged due to insufficient lubrication.
All Front Wheel Drive (FWD) vehicles:
It is not recommended to tow front wheel drive vehicles with the front
drive wheels on the ground. It is recommended to tow your vehicle with
the drive wheels on a dolly or two wheel car hauling trailer.
In case of a roadside emergency with a disabled vehicle (without access
to wheel dollies, car hauling trailer or flatbed transport vehicle) your
vehicle can be flat towed (all wheels on the ground) under the following
conditions:
•Place the transmission in N (Neutral).
•Maximum speed is 35 mph (56 km/h).
•Maximum distance is 50 miles (80 km).

•Maneuvering quickly to avoid an accident, pedestrian or obstacle
•Hitting a patch of ice
•Changing lanes on a snow-rutted road
•Entering a snow-free road from a snow-covered side street, or vice
versa
•Entering a paved road from a gravel road, or vice versa
•Hitting a curb while turning
•Cornering at excessive speeds while towing a heavily loaded trailer

The AdvanceTrac
system automatically turns on when the engine is
started. However, the system does not function when the vehicle is
traveling in R (Reverse).
If you are operating the speed control system and road conditions
change causing the AdvanceTrac
to activate, the AdvanceTrac
will
disengage the speed control. When driving conditions permit, you can
return to speed control by pressing RESUME. Refer toSpeed controlin
theDriver controlschapter.
The AdvanceTrac
button allows the
driver to control the availability of
the AdvanceTrac
system.
AdvanceTrac
system status is
indicated by the AdvanceTrac

indicator light in the instrument
cluster when the system is
deactivated.
If a failure is detected in the AdvanceTrac
system, the AdvanceTrac

indicator light in the instrument cluster will stay on. Have the vehicle
system serviced by an authorized dealer immediately.
If the vehicle is stuck in snow or mud or when driving in deep sand,
switching off the AdvanceTrac
system may be beneficial so the wheels
are allowed to spin. If your vehicle seems to lose engine power while
driving in deep sand or very deep snow, switching off the AdvanceTrac

stability enhancement feature will restore full engine power and will
enhance momentum through the obstacle.
Some drivers may notice a slight movement of the brake pedal when the
AdvanceTrac
performs a system self-check. During AdvanceTrac

operation you may experience the following:
•A rumble or grinding noise
