Oil pressure/Engine coolant
This light will come on when the
key is in the ON position and the:
²engine coolant temperature is
very high
²engine oil pressure is low
The light serves as a notice that a system needs your attention and to
check the engine coolant temperature gauge and the engine oil pressure
gauge.
Refer toEngine coolant temperature gaugeandEngine oil pressure
gaugein this chapter for more information.
Transmission control indicator light (TCIL) (if equipped)
Illuminates when the Transmission
Control Switch (TCS), refer to
Overdrive controlin theControls
and Featureschapter, has been
pushed turning the transmission
overdrive function OFF. When the TCIL (the word OFF on the gear
shift) light is on, the transmission does not operate in the overdrive
mode, refer to theDrivingchapter for transmission function and
operation.
The light may also flash steadily if a transmission malfunction is
detected. If the light does not come on when the Transmission Control
Switch is depressed or if the light flashes steadily, have your vehicle
serviced as soon as possible, damage to the transmission could occur.
Four wheel drive low (if equipped)
Momentarily illuminates when the
ignition is turned to the ON/START
position. Illuminates when
four-wheel drive low is engaged. If
the light continues to flash have the system serviced.
Four wheel drive indicator (if equipped)
Momentarily illuminates when the
ignition is turned to the ON/START
position. Illuminates when 4x4 range
is engaged. If the light continues to flash have the system serviced.

Installing the snowplow
Removing the blocker beam without installing snowplow
attachment hardware may affect air bag deployment in a crash.
Do not operate the truck unless either the blocker beam or snowplow
attachment hardware is installed on the vehicle.
Read the following instructions before installing a snowplow:
²Front GAWR must not exceed 63% of the GVW. Add ballast weight to
the back of the vehicle, if necessary. Refer to the Safety Compliance
Certification Label to find Front GAWR.
²The Front Axle Accessory Reserve Capacity and the Total Accessory
Reserve Capacity listed on the bottom right of the Safety Compliance
Certification Label will determine whether or not the addition of a
snowplow will overload your vehicle.
²The weight of the snowplow and supporting components distributed to
the front axle must not exceed the front accessory reserve capacity.
²The total weight of the snowplow and aftermarket equipment must
not exceed the Total Accessory Reserve Capacity.
²The weight of the installed snowplow and aftermarket equipment must
not load the vehicle beyond the GAWR (front/rear) and GVWR listed
on the Safety Compliance Certification Label.
²The total weight of the snowplow and aftermarket equipment must be
considered part of the payload and must not exceed the Gross
Combined Weight Rating (GCWR) for towing.
²Federal and most local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your dealer for additional
information.
²After installing a snowplow to the vehicle, ensure the vehicle's front
toe alignment and front ride height are within specification (reset if
required). These specifications are located in the vehicle's Workshop
Manual. Adherence to the toe, tire pressures and ride height
specification is important for proper tire wear, ride, handling and
headlight aim. Also, maintain the engine oil and transmission fluid
change intervals following the severe duty schedule.
Do not exceed the GVWR or the GAWR specified on the
certification label.

ENGINE OIL
Checking the engine oil
Refer to the scheduled maintenance guide for the appropriate intervals
for checking the engine oil.
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait a few minutes for the oil to drain into the
oil pan.

3. Set the parking brake and ensure the gearshift is securely latched in P
(Park) (automatic transmission) or 1 (First) (manual transmission).
4. Open the hood. Protect yourself from engine heat.
5. Locate and carefully remove the
engine oil level indicator (dipstick).
6. Wipe the indicator clean. Insert the indicator fully, then remove it
again.
²If the oil level isbetween the MIN and MAX marks,the oil level is
acceptable.DO NOT ADD OIL.

Maintenance
²Keep tires properly inflated and use only recommended size.
²Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
²Use recommended engine oil. Refer toLubricant Specifications.
²Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle scheduled maintenance guide.
Conditions
²Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
²Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
²Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
²To maximize the fuel economy, drive with the tonneau cover installed
(if equipped).
²Using fuel blended with alcohol may lower fuel economy.
²Fuel economy may decrease with lower temperatures during the first
12±16 km (8±10 miles) of driving.
²Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
²Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
²Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
²Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window sticker. Contact your
dealer if the window sticker is not supplied with your vehicle. The EPA
window sticker should be your guide for the fuel economy comparisons
with other vehicles.

fluid. However, these dual usage fluids may be used in transmissions that
require the MERCONtV type fluid.
MERCONtand MERCONtV type fluids are not interchangeable.
DO NOT mix MERCONtand MERCONtV. Use of a transmission
fluid that indicates dual usage (MERCONtand MERCONtV) in
an automatic transmission application requiring MERCONtmay
cause transmission damage. Use of any fluid other than the
recommended fluid may cause transmission damage.
