2007 Acura RDX engine

CONT INUED
The reading of the vehicle’s
temperature gauge on the
inf ormation display or multi-
inf ormation display (depending on
models) should stay in the midrange.
If it climbs to the H (Hot) mark, you
should determine the reason (hot
day, driving up a steep hill, etc.).If the temperature gauge reading
stays at the H (Hot) mark, turn of f
the engine. If you do not see steam or spray,
leave the engine running, and
watch the temperature gauge. If
the high heat is due to overloading,
the engine should start to cool
down almost immediately. If it
does, wait until the temperature
gauge comes down to the midpoint,
then continue driving. If you see steam and/or spray
coming f rom under the hood, turn
of f the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
If the coolant temperature rises to
224°F (118°C) or more, the
temperature gauge will appear on
the display and blink for several
times. At the same time, the beeper
will sound once.
If your vehicle overheats, you should
take immediate action. The only
indication may be the temperature
gauge climbing to the H (Hot) mark.
Or you may see steam or spray
coming f rom under the hood. Saf ely pull to the side of the road.
Put the transmission in Park, and
set the parking brake. Turn of f all
accessories, and turn on the
hazard warning indicators.

Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
Driving with the temperature gauge
reading at the H (Hot) mark can cause
serious damage to the engine.

Look for any obvious coolant leaks,
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
on page ).
If you don’t find an obvious leak,
check the coolant level in the
radiator reserve tank (see page
). 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.
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
befo re checking the radiato r. 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.
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. 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 on page ).

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.

Let the vehicle sit for a minute.
Op en the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers. If
the charging system
indicator comes on brightly
wh en the engine is running, the
battery is not being charged.
Safely
pull off the road, and shut
off the engine. Turn on the hazard
warning lights.
This
indicator should never
come on when the engine is
running. If it starts flashing or stays
on, the oil pressure has dropped very
low or lost pressure. Serious engine
damage is possible, and you should
take immediate action.
Start the engine, and watch the oil
pressure indicator. If it does not go
out within 10 seconds, turn off the
engine. There is a mechanical
problem that needs to be repaired
befo re you can continue driving
(see on page
). You
will also see a ‘‘CHECK
CHARGI NG SYSTEM’’ message on
the multi-information display (see
page ).
Immediately turn off all electri cal
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.
Go to a service station or garage
where you can get technical
assistance.
If
necessary, add oil to bring the
level back to the full mark on the
dipsti ck (see page ).
You
will also see an ‘‘OIL
PRESSURE LOW’’ message on the
multi-info rmation display (see page
). 1.

If the indicator comes on
while driving, it means one
of the engine’s emissions control
systems may have a problem. Even
though you may feel no difference in
your vehicle’s performance, it can
reduce your fuel economy and cause
increased emissions. Continued
operation may cause serious damag e.
If the indicator comes on repeatedly,
even though it may turn off as you
continue driving, have your vehicle
checked by your dealer as soon as
possible. If you have recently refueled your
vehicle, the indicator coming on
could be due to a loose or missing
fuel fill cap. Tighten the cap until it
clicks at least once. Tightening the
cap will not turn the indicator off
immediately; it can take several days
of norm al driving. The
indicator may also come on with
the ‘‘D’’ indicator.
You will also see a ‘‘CHECK
EMISSION SYSTEM’’ message on
the multi-information display (see
page ).
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics for the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not set,
the test cannot be completed.
If the battery in your vehicle has
been disconnected or gone dead,
these codes are erased. It takes at
least three days of driving under
various conditions to set the codes
again.
To check if they are set, turn the
ignition switch to the ON (II)
position, without starting the engine.
The malfunction indicator lamp will
come on for 20 seconds. If it then
goes off, the readiness codes are set.
If it blinks five times, the readiness
codes are not set. If possible, do not
take your vehicle for a state
emissions test until the readiness
codes are set. Ref er to for more
inf ormation (see page ). 418

Your vehicle has an electric vacuum
pump located in the engine
compartment. It enhances the
effectiveness of your vehic le’s brake
system more frequently when you
drive in cold weather or thinner air at
high altitude after the engine is
started.
When the electric vacuum pump is in
operation, it makes some mechanical
noises come from the engine
compartment. This is normal. The
brake system indicator (amber)
on the instrument panel norm ally
comes on for a few seconds when
you turn the ignition switch to the
ON (II) position. If it stays on after
the engine starts, press on the brake
pedal with your foot several times
until the indicator turns off. If the
indicator is still on or comes on again
after this procedure, there is a
problem in the brake system
including the electric vacuum pump.
If this happens, the brake pedal
might feel heavy when you press it.
Have your vehicle checked by your
dealer.
You will also see a ‘‘CHECK BRAKE
SYSTEM’’ message on the multi-
inf ormation display (see page ).
If you must drive the vehicle a short
distance in this condition, drive
slowly and caref ully.
If the ABS indicator and the VSA
system indicator come on with the
brake system indicator, have your
vehicle inspected by your dealer
immediately.

Your vehicle has several identif ying
numbers located in various places.
The vehicle identif ication number
(VIN) is the 17-digit number your
dealer uses to register your vehicle
f or warranty purposes. It is also
necessary f or licensing and insuring
your vehicle. The easiest place to
find the VIN is on a plate fastened to
the top of the dashboard. You can
seeitbylookingthroughthe
windshield on the driver’s side. It is
also on the certification label
attached to the driver’s doorjamb,
and is stamped on the engine
compartment bulkhead. The VIN is
also provided in bar code on the
certif ication label.
