coolant temperature VOLVO V4 2002 Owners Manual

2 Clock
3 Tachometer
Reads thousands of engine rpm. The needle should never be in the solid red range.
4 Trip odometer reset button
Press the button to reset the trip odometer. The ignition must be switched on.
5 Odometer
6 Speedometer
7 Trip odometer
Used for measuring shorter distances. The last digit indicates 1/10 mile/kilometer.
8 Fuel gauge
Fuel tank capacity: 16 US gallons (60 liters).
When the warning light comes on there is approximately 1.9 US gal. (7 liters) of fuel remaining. See "Refueling"
for additional information. When refueling the fuel gauge needle will not register until the volume of gasoline in
the tank exceeds 3.2 US gal. (12 liters).
9 Trip Computer/Ambient temperature
NOTE: See page 27- 29
for information on the trip computer.
10 Temperature gauge (engine coolant)
Do not drive the car with the pointer in the red range. The pointer should be approximately midway on the
gauge face when driving. If the pointer approaches the red range repeatedly, check coolant level. See page 117
.

pg. 112 Fuel/emissions systems
Fuel system
The fuel system is all electronic and is microprocessor controlled. It can continually compensate for variation in engine
load, speed and temperature to give the best economy and power. A mass air flow sensor measures the inducted air. In
this way the system can make instantaneous adjustments for changes in air temperature or density, thus always
assuring the best economy with the lowest possible exhaust emissions.
Heated oxygen sensor
This is an emission control system designed to reduce emissions and improve fuel economy. The heated oxygen sensor
monitors the composition of the exhaust gases leaving the engine. The exhaust gas analysis is fed into an electronic
module. This adjusts the air-fuel ratio to provide optimum conditions for combustion and efficient reduction of the
three major pollutants (hydrocarbons, carbon monoxide and oxides of nitrogen (NOx) by a three-way catalytic
converter.
Crankcase ventilation
The engine is provided with positive crankcase ventilation which prevents crankcase gases from being released into the
atmosphere. Instead, the crankcase gases are admitted to the intake manifold and cylinders.
Evaporative control system
The car is equipped with an evaporative control system which prevents gasoline vapor from being released into the
