INSTRUMENT CLUSTER DESCRIPTIONS
1. Fuel Gauge
The pointer shows the level of fuel in the fuel tank when
the ignition switch is in the ON position.
2. Fuel Door Reminder
The arrow in this symbol is a reminder that the
Fuel Filler Door is located on the left side of the
vehicle.
3. 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
ªHª, 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 ªHº, and you hear continuous chimes,
turn the engine off immediately, and call an autho-
rized dealer for service.

REVERSE
Use REVERSE for moving the vehicle rearward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL
Shift the gear selector lever into this gear only after the
vehicle has come to a complete stop. The engine may be
started in this range.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have an accident.
DRIVE Ð Six-Speed Transmission
This range should be used for most city and highway
driving. It provides the smoothest upshifts, downshifts,
and best fuel economy. However, use the Electronic
Range Select (ERS) mode by moving the leverÐ/+and
select the ª5º range when frequent transmission shifting
occurs while using the DRIVE range, 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). Under these conditions,
using the ª5º range will improve performance and
extend transmission life by reducing excessive shifting
and heat build-up.
DRIVE Ð Four-Speed Transmission
This range should be used for most city and highway
driving. It provides the smoothest upshifts, downshifts,
and best fuel economy. However, select the ª3º range
when frequent transmission shifting occurs while using
the DRIVE range, such as when operating the vehicle
332 STARTING AND OPERATING
Page 335 of 531

under heavy loading conditions, (i.e., in hilly terrain,
traveling into strong head winds or while towing heavy
trailers). Under these conditions, using the ª3º range will
improve performance and extend transmission life by
reducing excessive shifting and heat build-up.
CAUTION!
If the transmission operating temperature exceeds
acceptable limits, the vehicle computer will override
DRIVE and select ª5º range (on six-speed transmis-
sions) or ª3º range (on four-speed transmissions) by
changing shift points. This is done to prevent trans-
mission damage due to overheating.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows
you to move the gear selector lever to the left (-) or right
(+) when the gear selector lever is in the D (Drive)position, this allows the selection of the desired top gear.
For example, if the driver shifts the transmission into 3rd
gear, the transmission will never shift above 3rd gear, but
can shift down to 2nd or 1st gear automatically, when
needed.
Switching from ERS to D-Mode (Drive) can be done at any
vehicle speed. To shift from ªDriveº mode to ªERSº mode,
move gear selector lever to the left (-) once. The current gear
will be maintained as the top gear. To disable ERS, simply
press and hold the gear selector lever to the right (+) until
ªDº is displayed in the instrument cluster odometer.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid causing an accident or
personal injury.

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 ªVehicle Loadingº section
of this manual.
NOTE:Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the front and rear
axles must not be exceeded. For further information on
GAWRs, vehicle loading, and trailer towing, refer to
ªVehicle Loadingº in this section.
To determine the maximum loading conditions of your
vehicle, locate the statement, ªThe combined weight of
occupants and cargo should never exceed XXX kg or XXX
lbs.º on the Tire and Loading Information placard. Thecombined 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, ªThe combined weight of occu-
pants and cargo should never exceed XXX kg or XXX lbsº
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 kg or XXX lbs.
4. The resulting figure equals the available amount of
cargo and luggage load capacity. For example, if ªXXXº
amount equals 1,400 lbs (635 kg) and there will be five
each 150 lb (68 kg) passengers in your vehicle, the

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 capaci-
ties of your vehicle with varying seating configurations
and number and size of occupants. This table is for
illustration purposes only and may not be accurate for
the seating and load carrying capacity of your vehicle.
NOTE:For the following example, the combined weight
of occupants and cargo should never exceed 865 lbs (392
kg).

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.
Common Towing Definitions
The following trailer towing-related definitions will as-
sist 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/luggage and
trailer 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
9loaded and ready for operation9condition. 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 68 kg (150 lbs) allowance for the presence of a
driver).
