2000 Acura RL cooling

Gauge
s

Outside Temperature Indicator
This indicator displays the outside temperature in Fahrenheit in U.S.
models, and in Centigrade inCanadian models.
The temperature sensor is located in the front bumper. Therefore, the
temperature reading can be affected
by heat reflection from the road sur-
face, engine heat, and the exhaust
from the surrounding traffic. This can cause the temperature reading
not to be correct when your speed is
under 19 mph (30 km/h).
In certain weather conditions,
temperature readings near freezing (32°F, 0°C) could mean that ice is
forming on the road surface. Temperatur
e Gaug e
This shows the temperature of the engine's coolant. During normal
operation, the pointer should rise
from the bottom white 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 white mark. If it reaches
the red (Hot) mark, pull safely to the side of the road. Turn to page 280 for
instructions and precautions on checking the engine's cooling

system.
Fue
l Gaug e
This shows how much fuel you have. It is most accurate when the car is on
level ground. It may show slightly more or less than the actual amount
when you are driving on curvy or hilly roads.
The gauge stays at the same fuel level reading after you turn off theignition. When you add fuel, the
gauge slowly changes to the new
reading after you turn the ignitionswitch back ON (II).
Instrument s an d Control s

Climat
e Contro l Syste m

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 flow from the vents in the center and each side ofthe dashboard is adjustable. Move
the tab in the center of each vent up- and-down and side-to-side.
The side vents can be opened and closed with the dials next to them.
In the rear seat, you can also adjust
the ventilation when the climate con-
trol system is on (see page 132 ).
CENTE
R VENT S

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.
SID
E VENT S
For the climate control system to
provide heating and cooling, the engine must be running.

Climat
e Control System

3.5 RL without Navigation System

Fully-automati c Operatio n
To put the Automatic Climate Control in fully-automatic mode,
press the AUTO button and set the fan control dial to AUTO, then set
the desired temperature by turning
the temperature control dial. You willsee FULL AUTO in the system's
display. The light above either the or button also goes
on to show you which is selected.
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 from its current level to
the set temperature.
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 full 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.
In cold weather, the fan will not
come on automatically until the car
has been driven for a short time and
the heater starts to develop warm air. Pressing the OFF button shuts the
climate control system completely
off. Keep the system completely off
only for short periods. To keep stale
air and mustiness from collecting,
you should have the fan running at all times.

to adjust the temperature of the air
flow to a comfortable setting.

Towin
g a Traile r

Additional Trailer Equipment Many states and Canadian provinces
require special outside mirrors when
towing a trailer. Even if they don't,
you should install special mirrors if
you cannot clearly see behind you, or if the trailer creates a blind spot.
Ask your trailer sales or rental agency if any other items are
recommended or required for your

towing situation.
Pre-To
w Checklis t
When preparing to tow, and before driving away, be sure to check the
following: The vehicle has been properly
serviced, and the tires, brakes,
suspension, and cooling system
are in good operating condition.
All weights and loads are within limits (see pages 194 and 195 ).
The hitch, safety chain, and any other attachments are secure. All items on and in the trailer are
properly secured and cannot shift
while you drive. The lights and brakes on your
vehicle and the trailer are working
properly. Your vehicle tires and spare are
properly inflated (see page 242 ),and the trailer tires and spare are
inflated as recommended by the
trailer maker.
