Power Outlets
You can plug in auxiliary electrical
equipment. Just flip the outlet cover
open from the left edge of the cover
and follow the proper installation
instructions that are included with
any electrical equipment you install.
These circuits are protected by a
fuse and have maximum current
loads.
SeePower Outlets 067.
Performance and
Maintenance
Driving for Better Fuel
Economy
Economical Driving
How you drive, where you drive and
when you drive all affect fuel
economy.
Driving too fast, driving so slowly
that the engine knocks, driving with
the exhaust brake switched on all
the time, and frequently using the
exhaust brake to adjust your speed
can lead to poor fuel economy.
Drive at a constant speed as much
as possible. When accelerating,
increase your speed gently and
slowly, and up-shift early.
Maintain a constant cruising speed,
as traffic allows, and avoid sudden
stops. Frequent short trips, excessive
idling and use of the air conditioner
in cool weather when "Vent" would
provide adequate comfort, can all
lead to decreased fuel economy.
Warming up the engine for longer
than necessary, driving with the
vehicle overloaded and revving the
engine are a waste of fuel.
Overcooling of the engine not only
accelerates wear of the vital engine
parts but also hurts fuel economy.
The careful attention you give your
vehicle, as far as maintenance is
concerned, will also help fuel
economy.
Protection of Engine against
Overcooling
Overcooling of the engine not only
accelerates wear of the vital engine
parts but also hurts fuel economy.

24 In Brief
Diesel Exhaust Fluid
Diesel Exhaust Fluid (DEF) is used
with diesel engines to reduce the
amount of regulated emissions
produced. The DEF system must be
maintained for the vehicle to run
properly.
DEF is not a fuel additive. For
refilling instructions, seeDiesel
Exhaust Fluid 0170. DEF should
not be mixed with or added to diesel
fuel. DEF freezes when exposed to
temperature below −11 °C (12 ° F).
Locating Diesel Exhaust Fluid
DEF can be purchased at a dealer.
It can also be purchased at
authorized vehicle and truck
dealerships. Additionally, some
diesel truck fueling stations or
retailers may have DEF for
purchase. See Recommended
Fluids and Lubricants 0326. When the remaining level of DEF
becomes excessively low the DEF
gauge will change color from green
to amber. In addition, warning and
indicator lights will come on and
engine power will be reduced so the
vehicle speed will not exceed
89 km/h (55 MPH). See
Diesel
Exhaust Fluid 0170.

Storage 63
Do not Carry Fuel and Spray Cans
in the Cab
{Danger
It is extremely dangerous to carry
fuel and spray cans in the cab.
If such a container were to ignite
or rupture, it could cause a fire or
explosion. You and others could
be seriously injured.

Instruments and Controls 71
Speedometer
The speedometer shows the
vehicle's speed in either kilometers
per hour (km/h) or miles per
hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
Each time the reset knob is pressed
with the engine control switch in the
ON position, the odometer/trip meter
shows ODO, TRIP A, and TRIP B in
this sequence. With the key
removed, the odometer and trip
meter continue to indicate for about
five minutes.
Odometer Check Switch
Press the Odometer Check switch
to display the odometer and trip
meter mileage after the key is
turned off. The fuel gauge will also
operate when this switch is pressed.
The DIC and some lights will
illuminate on the instrument panel.
Trip Odometer
The trip odometer shows how far
the vehicle has been driven since
the trip odometer was last reset.
Press the trip odometer reset stem
next to the odometer to switch
between the odometer and trip
odometer.
To reset the trip odometer to zero,
press and hold the trip odometer
reset stem while TRIP A or TRIP B
is displayed. The engine control
switch should be in the ON position.When the battery is disconnected,
TRIP A and TRIP B will be reset to
zero. The per trip fuel economy is
also reset by the TRIP B reset. See
Driver Information Center (DIC)

82.
When you turn the engine control
switch to the ON position, the
odometer/trip odometer shows what
was displayed the last time the
engine control switch was turned to
LOCK or ACC.
To set the odometer to display each
time you turn the engine control
switch to the ON position, turn the
engine control switch to LOCK or
ACC while the odometer is
displayed. With the reset stem
pressed, turn the engine control
switch to the ON position and then
within three seconds, turn the
engine control switch back to the
LOCK or ACC position. Follow the
same procedure to cancel the
setting.

72 Instruments and Controls
Tachometer
The tachometer displays the engine
speed in revolutions per
minute (rpm). The red zone
indicates a range of dangerous
engine speeds beyond permissable
levels. Do not drive your vehicle
with the needle in the red zone.
Caution
Excercise extreme care when
shifting down on a steep
downslope. The engine speed
may exceed the critical speed,
which can damage the vehicle.
Fuel Gauge
With the engine control switch in the
ON position, the fuel gauge
indicates about how much fuel is left
in the tank.
To check the fuel level with the
engine control switch in the LOCK
position, press the Odometer Check
switch.
Fill the tank well before it
approaches empty. After filling up
the fuel tank, it takes awhile for the
fuel gauge needle to stabilize after
the engine control switch is turned
to the ON position. If the fuel tank is
filled while the engine is off, but theengine control switch is in the ON
position, the fuel gauge needle
takes awhile to show the correct
reading.
See
“Low Fuel Warning Light” in
Driver Information Center (DIC) 082
and Running Out of Fuel 0212.
Engine Coolant
Temperature Gauge
With the engine control switch in the
ON position, this gauge indicates
the temperature of the engine
coolant. “C”means cold while “H”
means hot. During operation, the
