Engine oil pressure gauge:
Indicates engine oil pressure. The
needle should stay in the normal
operating range (between “L” and
“H”). If the needle falls below the
normal range, stop the vehicle, turn
off the engine and check the engine
oil level. Add oil if needed. If the oil
level is correct, have your vehicle checked at your authorized dealer.
Fuel gauge: Indicates
approximately how much fuel is left
in the fuel tank (when the ignition
is in the on position). The fuel
gauge may vary slightly when the
vehicle is in motion or on a grade.
The FUEL icon and arrow indicates
which side of the vehicle the fuel
filler door is located.
Refer to Filling the tank in the Maintenance and Specifications
chapter for more information.
Battery voltage gauge (manual
transmission only): Indicates the
battery voltage when the ignition is
in the on position. If the pointer
moves and stays outside the normal
operating range, have the vehicle’s
electrical system checked as soon as
possible.
Transmission fluid temperature gauge (automatic transmission
only): If the gauge is in the:
Normal area– the transmission
fluid is within the normal operating
temperature (between “H” and “C”). Instrument Cluster

Operating tips
• To reduce fog build up on the windshield during humid weather, place
the air flow selector in the
position.
• To reduce humidity build up inside the vehicle, do not drive with the
air flow selector in the O (Off) position.
• Do not put objects under the front seats that will interfere with the
airflow to the rear seats.
• Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
• To improve the A/C cool down, drive with the windows slightly open
for 2–3 minutes after start up or until the vehicle has been “aired out.”
During extreme high ambient temperatures when idling stationary for
extended periods of time in gear, it is recommended to run the A/C in
the MAX A/C position, reduce blower fan speed from the highest setting
and put the vehicle’s transmission into the P (PARK) gear position
(automatic transmission only) to continue to receive cool air from your
A/C system.
For maximum cooling performance in MAX A/C mode:
1. Move the temperature control to the coolest setting.
2. Set the fan to the highest speed initially, then adjust in order to
maintain comfort.
To aid in side window defogging and demisting in cold weather:
1. Select
.
2. Select A/C.
3. Set the temperature control to maintain comfort.
4. Set the fan speed to highest setting.
5. Direct the outer instrument panel vents towards the side windows. Climate Controls

Operating tips
• To reduce fog build up on the windshield during humid weather, place
the air flow selector in the position.
• To reduce humidity build up inside the vehicle, do not drive with the
system off, or with recirculated air engaged and A/C off.
• Do not put objects under the front seats that will interfere with the
airflow to the back seats.
• Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
• To improve the A/C cool down, drive with the windows slightly open

For maximum cooling performance (MAX A/C):
Automatic operation:
1. Press AUTO for full automatic operation.
2. Do not override A/C or (recirculated air).
3. Set the temperature to 60°F (16°C).
Override operation:
1. Select air distribution.
2. Select A/C and (recirculated air). Use (recirculated air) with
A/C to provide colder airflow.
3. Set the temperature to 60°F (16°C).
4. Set highest fan speed initially, then adjust to maintain comfort. Climate Controls

Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. Contact your authorized dealer or a
reliable trailer dealer as soon as possible if you require assistance. Tires, Wheels and Loading

• Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
• To eliminate excessive transmission shifting, activate the Tow/Haul
feature. This will also assist in transmission cooling. For additional
information, refer to Automatic transmission operation in the
Driving chapter.
• Anticipate stops and brake gradually.
• Do not exceed the GCWR rating or transmission damage may occur.
• Your vehicle may be equipped with a temporary or conventional spare
tire. If the spare tire is different in size (diameter and/or width), tread
type (All-Season or All-Terrain) or is from a different manufacturer
other than the road tires on your vehicle, your spare tire is considered
“temporary”. Consult information on the spare Tire Label or Safety
Compliance Certification Label for limitations when using.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your scheduled maintenance
information for more information.
Trailer towing safety tips
General
• Ensure that the trailer, safety chains and 7–pin electrical connectors
are securely fastened.
• Make sure the truck receiver, draw bar, and coupler are properly
connected and adjusted.
• Check rear view and side mirrors for proper visibility especially when
towing trailer wider than the truck.
• When turning make wide turns to allow trailer tires to properly clear
any obstacles.
• When towing, operate the vehicle at lower speeds than you would
when not towing a trailer. The likelihood of trailer sway is greater at
higher speeds.
• Be prepared for trailer sway due to buffeting when larger vehicles
pass in either direction.
• 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 lubricant if not already soTires, Wheels and Loading
