floor vents and the defroster vents at
the base of the windshield. To Turn Everything Off
If you press the OFF button, the
climate control system shuts off
completely.
●Keep the system off for short
periods only.●To keep stale air and mustiness
from collecting, you should have
the fan running at all times.

Dual Temperature Control
Your vehicle has four temperature
control buttons, two for the driver,
and two for the front passenger.
The driver's side and the passenger's
side can be controlled independently
by adjusting these buttons when the
indicator in the DUAL button is lit.
Temperature Control Buttons
To set the driver's side temperature
to a different value than the
passenger's, press the DUAL button,
then press the temperature control
buttons (
or
) on the driver's side.
To set the passenger's side to a
different value than the driver's,
press the temperature control
buttons (
or
) on the passenger's
side. You can adjust the passenger's
side without pressing the DUAL
button first.

Audio AntennaYour vehicle is equipped with an
antenna at the rear of the roof. Before
using a‘‘drive-through ’’car wash,
remove the antenna by unscrewing it by
hand. This prevents the antenna from
being damaged by the car wash
brushes. Intercooler
Your vehicle is equipped with a
intercooler on the engine to cool the
air flow from a turbo charger into the
engine. The intercooler fins bend
easily. Do not push them with your
finger.
Do not spray water (from such sources
as garden hoses, high pressure
sprayers) into the engine compartment.
It may cause serious damage to your
vehicle, and could also damage the
intercooler fins.
Dust and Pollen Filter
This filter removes the dust and
pollen that is brought in from the
outside through the climate control
system.
Have your dealer replace the filter
when this service is indicated by a
maintenance message on the multi-
information display. It should be
replaced every 15,000 miles (24,000
km) if you drive primarily in urban
areas that have high concentrations
of soot in the air, or if the flow from
the climate control system becomes
less than usual.

Although this seems like a simple
procedure, you should take several
precautions.
A battery can explode if you do
not follow the correct
procedure, seriously injuring
anyone nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery.
You cannot start your vehicle by
pushing or pulling it.
To Jump Start Your Vehicle:1. Open the hood, and check the physical condition of the battery.
In very cold weather, check the
condition of the electrolyte. If it
seems slushy or frozen, do not try
jump starting until it thaws.If a battery sits in extreme cold, the
electrolyte inside can freeze. Attempting
to jump start with a frozen battery can
cause it to rupture.
2. Turn off all electrical accessories:heater, A/C, climate control, audio
system, lights, etc. Put the
transmission in Park, and set the
parking brake.
The numbers in the illustration
show you the order to connect the
jumper cables.

5. Look for any obvious coolantleaks, such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you
continue driving (see Emergency
Towing on page 475).
6. If you do not find an obvious leak, check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
7. If there was no coolant in the reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the reading
reaches the middle of the
temperature gauge or lower before
checking the radiator.
Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.
8. Using gloves or a large heavy cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. After the
pressure releases, push down on
the cap, and turn it until it comes
off. 9. Start the engine, and set the
temperature to maximum heat
(climate control to AUTO at
‘‘
’’). Add coolant to the radiator
up to the base of the filler neck. If
you do not have the proper coolant
mixture available, you can add
plain water. Remember to have the
cooling system drained and refilled
with the proper mixture as soon as
you can.
10. Put the radiator cap back on tightly. Run the engine, and watch
the temperature gauge. If it goes
back to the H mark, the engine
needs repair (see Emergency
Towing on page 475).
11. If the temperature stays normal, check the coolant level in the
radiator reserve tank. If it has gone
down, add coolant to the MAX
mark. Put the cap back on tightly.

The tires on your vehicle meet all
U.S. Federal Safety Requirements.
All tires are also graded for
treadwear, traction, and temperature
performance according to
Department of Transportation (DOT)
standards. The following explains
these gradings.
Uniform Tire Quality Grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:Treadwear 200
Traction AA
Temperature A
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades. Treadwear
The treadwear grade is a
comparative rating based on the wear
rate of the tire when tested under
controlled conditions on a specified
government test course. For
example, a tire graded 150 would
wear one and one-half (1 1/2) times
as well on the government course as
a tire graded 100. The relative
performance of tires depends upon
the actual conditions of their use,
however, and may depart
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.
Traction
The traction grades, from highest to
lowest, are AA, A, B, and C. Those
grades represent the tire's ability to
stop on wet pavement as measured
under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction
performance.
Warning: The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.DOT Tire Quality Grading (U.S. Vehicles)48211/06/16 17:42:51 12 ACURA RDX MMC North America Owner's M 50 31STK650 enu

The burning of gasoline in your
vehicle's engine produces several by-
products. Some of these are carbon
monoxide (CO), oxides of nitrogen
(NOx), and hydrocarbons (HC).
Gasoline evaporating from the tank
also produces hydrocarbons.
Controlling the production of NOx,
CO, and HC is important to the
environment. Under certain
conditions of sunlight and climate,
NOx and HC react to form
photochemical‘‘smog. ’’Carbon
monoxide does not contribute to
smog creation, but it is a poisonous
gas. The Clean Air Act
The United States Clean Air Act
ᤳ
sets standards for automobile
emissions. It also requires that
automobile manufacturers explain to
owners how their emissions controls
work and what to do to maintain
them. This section summarizes how
the emissions controls work.
Scheduled maintenance is on page
418.ᤳIn Canada, Acura vehicles comply
with the Canadian emission
requirements, as specified in an
agreement with Environment
Canada, at the time they are
manufactured. Crankcase Emissions Control
System
Your vehicle has a positive crankcase
ventilation system. This keeps
gasses that build up in the engine's
crankcase from going into the
atmosphere. The positive crankcase
ventilation valve routes them from
the crankcase back to the intake
manifold. They are then drawn into
the engine and burned.
Evaporative Emissions Control
System
As gasoline evaporates in the fuel
tank, an evaporative emissions
control canister filled with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is off. After
the engine is started and warmed up,
the vapor is drawn into the engine
and burned during driving.
