NOTE:
• Tighten the fuel filler cap until you hear a “clicking”sound. This is an indication that the fuel filler cap is prop -
erly tightened.
• If the gas cap is not tightened properly, the MIL may come on. Be sure the gas cap is tightened every time the vehicle
is refueled.
VEHICLE LOADING
As required by National Highway Traffic Safety Administra -
tion regulations, your vehicle has a certification label affixed
to the driver's side door or B-Pillar.
If seats are removed for carrying cargo, do not exceed the
specified GVWR and GAWR.
Vehicle Certification Label
Your vehicle has a Vehicle Certification Label affixed to the
drivers side B-Pillar or the rear of the driver’s door.
The label contains the following information:
• Name of manufacturer
• Month and year of manufacture
• Gross Vehicle Weight Rating (GVWR)
• Gross Axle Weight Rating (GAWR) front
• Gross Axle Weight Rating (GAWR) rear
• Vehicle Identification Number (VIN)
• Type of vehicle
• Month, Day, and Hour of manufacture (MDH)
The bar code allows a computer scanner to read the VIN.
• A fire may result if gasoline is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place gas containers on the ground
while filling.
CAUTION!
• Damage to the fuel system or emissions control system could result from using an improper fuel tank filler
tube cap. A poorly fitting cap could let impurities into
the fuel system and may cause the “Malfunction Indi -
cator Light (MIL)” to turn on, due to fuel vapors
escaping from the system.
• To avoid fuel spillage and overfilling, do not “top off” the fuel tank after filling.
WARNING! (Continued)

192 STARTING AND OPERATING
Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-pin
wiring harness. Use a factory approved trailer harness and
connector.
NOTE:
Do not cut or splice wiring into the vehicle’s wiring harness.
The electrical connections are all complete to the vehicle but
you must mate the harness to a trailer connector. Refer to the
following illustrations.NOTE:
• Disconnect trailer wiring connector from the vehicle
before launching a boat (or any other device plugged into
vehicle’s electrical connect) into water.
• Be sure to reconnect once clear from water area.
Four-Pin Connector
CAUTION!
If the trailer weighs more than 1,000 lbs (453 kg) loaded,
it should have its own brakes and they should be of
adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal effort,
and longer stopping distances.

194 STARTING AND OPERATING
Electronic Range Select (ERS)
• When using the ERS shift control, select the highest gearthat allows for adequate performance and avoids frequent
downshifts. For example, choose “5” if the desired speed
can be maintained. Choose “4” or “3” if needed to main -
tain the desired speed.
• To prevent excess heat generation, avoid continuous driving at high RPM. Reduce vehicle speed as necessary to
avoid extended driving at high RPM. Return to a higher
gear range or vehicle speed when grade and road condi -
tions allow.
Speed Control — If Equipped
• Do not use on hilly terrain or with heavy loads.
• When using the Speed Control, if you experience speed drops greater than 10 mph (16 km/h), disengage until you
can get back to cruising speed.
• Use Speed Control in flat terrain and with light loads to maximize fuel efficiency. Cooling System
To reduce potential for engine and transmission over
-
heating, take the following actions:
City Driving
• In city traffic — while stopped, place the transmission in NEUTRAL, but do not increase engine idle speed.
Highway Driving
• Reduce speed.
• Temporarily turn off air conditioning.

STARTING AND OPERATING 197
Driving Through Water
Driving through water more than a few inches/centimeters
deep will require extra caution to ensure safety and prevent
damage to your vehicle.
Flowing/Rising WaterShallow Standing Water
Although your vehicle is capable of driving through shallow
standing water, consider the following Cautions and Warn
-
ings before doing so.
WARNING!
Do not drive on or across a road or path where water is
flowing and/or rising (as in storm run-off). Flowing
water can wear away the road or path's surface and cause
your vehicle to sink into deeper water. Furthermore,
flowing and/or rising water can carry your vehicle away
swiftly. Failure to follow this warning may result in
injuries that are serious or fatal to you, your passengers,
and others around you.
WARNING!
• Driving through standing water limits your vehicle’s traction capabilities. Do not exceed 5 mph (8 km/h)
when driving through standing water.
• Driving through standing water limits your vehicle’s braking capabilities, which increases stopping
distances. Therefore, after driving through standing
water, drive slowly and lightly press on the brake pedal
several times to dry the brakes.
• Failure to follow these warnings may result in injuries that are serious or fatal to you, your passengers, and
others around you.

Rear Jacking Location3. Turn the handle on the jack screw to the right until the
jack head is properly engaged in the described location.
Do not raise the vehicle until you are sure the jack is
securely engaged.
4. Raise the vehicle by turning the jack screw to the right until the tire just clears the surface and enough clearance
is obtained to install the spare tire. Minimum tire lift
provides maximum stability.
5. Remove the wheel lug bolts. For vehicles with wheel covers, remove the cover from the wheel by hand. Do not
pry the wheel cover off. Then pull the wheel off the hub.
6. Install the spare tire. Lightly tighten the wheel lug bolts using the bolt install wrench.
WARNING!

Being under a jacked-up vehicle is dangerous. The vehicle
could slip off the jack and fall on you. You could be
crushed. Never get any part of your body under a vehicle
that is on a jack. If you need to get under a raised vehicle,
take it to a service center where it can be raised on a lift.

CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in the Jacking
Instructions for this vehicle.
WARNING!
Raising the vehicle higher than necessary can make the
vehicle less stable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
remove the tire.
