minder System (BeltAlert ™ )  in the Occupant Restraints
section for more information.
14. Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. If the engine is critically hot, a continuous
chime will sound for 4 minutes. After the chime
turns off, the engine will still be critically hot until the
light turns off.
15. Vehicle Theft Alarm Light — If Equipped
This light will flash for approximately 15 sec-
onds when the vehicle theft alarm is arming.
(See page 26 for more information.)
16. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily. The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!Driving with a hot engine cooling system could
damage your vehicle. If temperature gauge reads (H),
pull over and stop the vehicle. Idle the vehicle with
the air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “ H ” , and you hear continuous chimes, turn the
engine off immediately, and call for service.208 UNDERSTANDING YOUR INSTRUMENT PANEL

“ R ” Reverse
Shift into this range only after the vehicle has come to a
complete stop.
“ N ” Neutral
Engine may be started in this range.
“ D ” Overdrive
For most city and highway driving, it provides smoothest
upshifts and downshifts and best fuel economy. When
frequent transmission shifting occurs while using the
“ D ” Overdrive position, such as when operating the
vehicle under heavy loading conditions, (i.e. in hilly
terrain, traveling into strong head winds or while towing
heavy trailers), using the “ 3 ” position will improve
performance and extend transmission life by reducing
excessive shifting and heat build-up.
“ 3 ” Drive
This range eliminates shifts into Overdrive. The transmis-
sion will operate normally in First, Second and Third while in this range. The “ 3 ” position should also be used
when descending steep grades to prevent brake system
distress.
NOTE: Using the “ 3 ” range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up.
“ L ” Low
This range should be used for engine braking when
descending very steep grades. In this range, upshifts will
occur only to prevent engine overspeed while downshifts
occur earlier than other gear range selections.
NOTE: The vehicle computer will over ride Overdrive
and “ 3 ” Drive ranges by changing shift points if the
transmission operating temperature exceeds acceptable
limits. This is done to prevent transmission damage due
to overheating.312 STARTING AND OPERATING

3) the tire size designed for your vehicle
4) the cold tire inflation pressures for the front, rear
and spare tires.
Loading
The vehicle maximum load on the tire must not exceed
the load carrying capacity of the tire on your vehicle. You
will not exceed the tire ’ s load carrying capacity if you
adhere to the loading conditions, tire size, and cold tire
inflation pressures specified on the “ Tire and Loading
Information ” placard and in the “ Vehicle Loading ” sec-
tion of this manual.
NOTE: Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWR ’ s) for the front and rear
axles must not be exceeded. For further information on
GAWR ’ s, vehicle loading, and trailer towing, refer to the
“ Vehicle Loading ” section of this manual. To determine the maximum loading conditions of your
vehicle, locate the statement “ The combined weight of
occupants and cargo should never exceed XXX kg or XXX
lbs. ” on the Tire and Loading Information placard. The
combined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never exceed
the weight referenced here.
Steps for Determining Correct Load Limit
1. Locate the statement “ The combined weight of occu-
pants and cargo should never exceed XXX pounds ” 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 pas-
sengers from XXX kilograms or XXX pounds. STARTING AND OPERATING 325
5

4. The resulting figure equals the available amount of
cargo and luggage load capacity. For example, if “ XXX ”
amount equals 1400 lbs. and there will be five 150 lb.
passengers in your vehicle, the amount of available cargo
and luggage load capacity is 650 lb. (since 5 x 150 = 750,
and 1400 – 750 = 650 lb.)
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.
NOTE: The following table shows examples on how to
calculate total load, cargo/luggage and towing capacities
of your vehicle with varying seating configurations and
number and size of occupants. This table is for illustra-
tion purposes only and may not be accurate for the
seating and load carry capacity of your vehicle.
NOTE: For the following example the combined weight
of occupants and cargo should never exceed 865 lbs. (392
Kg).326 STARTING AND OPERATING

TRAILER TOWING
In this section you will find safety tips and information
on limits to the type of towing you can reasonably do
with your vehicle. Before towing a trailer carefully re-
view this information to tow your load as efficiently and
safely as possible.
To maintain warranty coverage, follow the requirements
and recommendations in this manual concerning ve-
hicles used for trailer towing.350 STARTING AND OPERATING

Common Towing Definitions
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR.
Gross Trailer Weight (GTW)
The gross trailer weight (GTW) is the weight of the trailer
plus the weight of all cargo, consumables and equipment
(permanent or temporary) loaded in or on the trailer in its
 loaded and ready for operation  condition. The recom-
mended way to measure GTW is to put your fully loaded
trailer on a vehicle scale. The entire weight of the trailer
must be supported by the scale. Gross Combination Weight Rating (GCWR)
The gross combination weight rating (GCWR) is the total
permissible weight of your vehicle and trailer when
weighed in combination. (Note that GCWR ratings in-
clude a 150 lbs (68 kg) allowance for the presence of a
driver).
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR. STARTING AND OPERATING 351
5

WARNING!It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have an accident.
Tongue Weight (TW)
The downward force exerted on the hitch ball by the
trailer. In most cases it should not be less than 10% or
more than 15% of the trailer load. You must consider this
as part of the load on your vehicle.
Frontal Area
The maximum height and maximum width of the front of
a trailer.
Trailer Sway Control
The trailer sway control is a telescoping link that can be
installed between the hitch receiver and the trailer tongue that typically provides adjustable friction associated with
the telescoping motion to dampen any unwanted trailer
swaying motions while traveling.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch ball or
some other connecting point of the vehicle. These kind of
hitches are the most popular on the market today and
they ’ re commonly used to tow small- and medium-sized
trailers.
Weight-Distributing Hitch
A weight-distributing hitch includes a receiver attached
to the tow vehicle, plus a removable hitch head and
spring bar assembly that fits into the receiver opening
and hook up brackets that connect the spring bars to the
trailer frame.352 STARTING AND OPERATING

Trailer Hitch Classification
Your vehicle may be factory equipped for safe towing of
trailers weighing over 2,000 lbs (907 kg) with the optional
Trailer Tow Prep Package. See your dealer for package
content.
The following chart provides the industry standard for
the maximum trailer weight a given trailer hitch class can
tow and should be used to assist you in selecting the
