2003 Acura CL cooling

This indicator displays the outside
temperature in Fahrenheit in U.S.
models, and in Centigrade in
Canadian models.
In certain weather conditions,
temperature readings near f reezing
(32°F, 0°C) could mean that ice is
f orming on the road surf ace. The temperature sensor is located in
the f ront bumper. Theref ore, the
temperature reading can be af f ected
by heat ref lection f rom the road sur-
f ace, engine heat, and the exhaust
f rom the surrounding traf f ic. This
can cause the temperature reading
not to be correct when your speed is
under 19 mph (30 km/h).This shows how much f uel you have.
It is most accurate when the car is on
level ground. It may show slightly
more or less than the actual amount
whenyouaredrivingoncurvyor
hilly roads.
This shows the temperature of the
engine’s coolant. During normal
operation, the pointer should rise
from the bottom mark to about the
middle of the gauge. In severe
driving conditions, such as very hot
weather or a long period of uphill
driving, the pointer may rise to near
the upper red mark. If it reaches the
red (Hot) mark, pull saf ely to the
side of the road. Turn to page f or
instructions and precautions on
checking the engine’s cooling
system. The needle returns to the bottom
after you turn off the ignition. The
gauge shows the f uel level reading
immediately af ter you turn the
ignition switch back ON (II).

Avoid driving with an extremely low
f uel level. Running out of f uel could
cause the engine to misf ire, damaging
the catalytic converter.

The automatic climate control
system in your Acura picks the
proper combination of air condi-
tioning, heating, and ventilation to
maintain the interior temperature
you select. The system also adjusts
the fan speed and air flow levels.
The direction of air f low f rom the
vents in the center and each side of
the dashboard is adjustable. Move
the tab in the center of each vent up-
and-down and side-to-side.The climate control system draws air
through the exterior vents at the
bottom of the windshield. Keep
these vents clear of leaves and other
debris.For the climate control system to
provide heating and cooling, the
engine must be running.

When you set the temperature to its
lower limit (60°F/18°C) or its upper
limit (90°F/32°C), the system runs
at f ull cooling or heating only. It does
not regulate the interior temperature. When the temperature is set
between the lower and upper limits,
the system regulates the interior
temperature to the set value.
The system automatically selects the
proper mix of conditioned and/or
heated air that will, as quickly as
possible, raise or lower the interior
temperature f rom its current level to
the set temperature.
