2012 Acura RDX check engine

If this indicator blinks while driving,
it indicates the differential
temperature is too high.
You will also see an‘‘SH-AWD DIFF
TEMP. HIGH ’’message on the multi-
information display (see page 80).
Pull to the side of the road when it is
safe, shift to Park, and let the engine
idle until the indicator goes out. If
the indicator does not go out, take
your vehicle to a dealer to have it
checked.
For more information, see page 385.Continuing to drive with the SH-AWD
indicator blinking may cause serious
damage to the system.
Low Tire Pressure/TPMS
Indicator
This indicator normally comes on for
a few seconds when you turn the
ignition switch to the ON (II)
position.
This indicator has two functions:
1. If it comes on while driving, it indicates that one or more of your
vehicle's tires are significantly low
on pressure. You will also see a
‘‘CHECK TIRE
PRESSURE ’’message on the multi-
information display (see page 79).
Check the tire pressure monitor on
the multi-information display and
determine the cause (see page 392).
If this happens, pull to the side of the
road when it is safe, check which tire
has lost pressure on the multi-
information display, and determine
the cause. If it is because of a flat tire,
have the flat tire repaired as soon as
possible. If two or more tires are
underinflated, call a professional
towing service. For more
information, see page 475.

SH-AWD Torque Distribution
MonitorOn SH-AWD modelsThis monitor shows how much
torque is being delivered to each
wheel. For more information, see
page 384.
Tire Pressure Monitor
You can see the pressure of each tire
in this monitor. If one or more tire
pressure are low, inflate them to the
correct pressure. For more
information, see page 392.Temperature Gauge
This shows the temperature of the
engine's coolant. During normal
operation, the reading should rise
from the
‘‘C (Cold)’’ 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 reading may rise to near
the ‘‘H (Hot) ’’mark of the gauge. If it
reaches the ‘‘H ’’mark, pull safely to
the side of the road. See page 463 for
instructions and precautions on
checking the engine's coolant
system.

If the engine has just been started, it
may take a short time for the system
to display the rearview.
The camera display brightness is
adjusted automatically by sensors. If
you use the camera display
continuously at high temperature,
the image will gradually dim and
eventually turn off automatically. If
you change to another shift position,
the camera display will come on
again when you return to reverse.
The inside mirror will be hot when
you use the monitor for an extended
period of time.
If a bright light (such as sunlight) is
reflected on the mirror, the image
may be difficult to see.
Rearview Camera Guide Line
The camera display has parking
guide lines that indicate distance
from your vehicle.
1st Line 24in (0.6m)
2nd Line 39in (1m)
3rd Line 79in (2m)
4th Line 118in (3m)
NOTE●The rearview camera has a unique
lens that makes objects appear
closer than they actually are.●The rearview camera display has a
limited coverage, and the size and
position of objects may appear
different than they actually are.
Make sure to check the
surrounding area carefully.
To turn the guide line on and off,
hold the power button for more than
3 seconds when the shift is in
reverse, the on/off setting will be
kept when you change gear and
return to reverse.

Before you begin driving your
vehicle, you should know what
gasoline to use and how to check the
levels of important fluids. You also
need to know how to properly store
luggage or packages. The
information in this section will help
you. If you plan to add any
accessories to your vehicle, please
read the information in this section

5. Screw the fuel fill cap back on untilit clicks at least once. If you do not
properly tighten the cap, you will
see a ‘‘TIGHTEN FUEL CAP ’’
message on the multi-information
display (see right column on this
page), and the malfunction
indicator lamp may also come on
(see page 466).
6. Push the fuel fill door closed until it latches. Tighten Fuel Cap Message
If your fuel fill cap is loose or
missing, a
‘‘TIGHTEN FUEL CAP ’’
message appears on the multi-
information display after you start the
engine. Turn the engine off, and confirm the
fuel fill cap is installed. If it is, loosen
it, then retighten it until it clicks at
least once. When you can restart the
engine, the message appears again.
The message goes off after several
days of normal driving once you
tighten or replace the fuel fill cap. To
scroll to another message, press the
INFO (
/
) button.
If the system still detects a leak in
your vehicle's evaporative emissions
system, the malfunction indicator
lamp (MIL) comes on. If the fuel fill
cap was not already tightened, turn
the engine off, and check or
retighten the fuel fill cap until it
clicks at least once. The MIL should
go off after several days of normal
driving once the cap is tightened or
replaced. If the MIL does not go off,
have your vehicle inspected by a
dealer. For more information, see
page 466.

To close the hood, lift it up slightly to
remove the support rod from the
hole. Put the support rod back into
its holding clip. Lower the hood to
about a foot (30 cm) above the
fender, then let it drop. Make sure it
is securely latched.Oil Check
Park the vehicle on a level surface.
Wait a few minutes after turning the
engine off before you check the oil.
1. Remove the dipstick (orange loop).
2. Wipe off the dipstick with a clean
cloth or paper towel.
3. Hold the dipstick with a clean cloth or paper towel, and then
insert it all the way back in its
hole.
Make sure the ‘‘UP ’’mark on the
loop is facing up when you insert
the dipstick.
4. Remove the dipstick again, and check the level. It should be
between the upper and lower
marks.
If it is near or below the lower mark,
see Adding Engine Oil on page 420.

Engine Coolant CheckLook at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, seeAdding
Engine Coolant on page 424 for
information on adding the proper
coolant. Refer to
Owner's Maintenance
Checks on page 417 for information
about checking other items on your
vehicle. Actual Mileage and EPA Fuel
Economy Estimates Comparison.
Fuel economy is not a fixed number.
It varies based on driving conditions,
driving habits and vehicle condition.
Therefore, it is not possible for one
set of estimates to predict fuel
economy precisely for all drivers in
all environments.
The EPA fuel economy estimates
shown in the example to the right are
a useful tool for comparison when
buying a vehicle. EPA estimates
include:
City MPG
－Represents urban
driving in a vehicle in light traffic. A
range of miles per gallon achieved is
also provided.
Highway MPG －Represents a
mixture of rural and interstate
driving, in a warmed-up vehicle,
typical of longer trips in free-flowing
traffic. A range of miles per gallon
achieved is also provided.

Improving Fuel EconomyVehicle MaintenanceA properly maintained vehicle
maximizes fuel economy. Poor
maintenance can significantly reduce
fuel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the
information display (seeOwner's
Maintenance Checks on page 417).
For example:●Use the required engine oil (see
page 420).●Maintain proper tire inflation －
An underinflated tire increases
‘‘ rolling resistance, ’’which reduces
fuel economy.●Avoid carrying excess weight in
your vehicle －It puts a heavier
load on the engine, increasing fuel
consumption.
●Keep your vehicle clean －In
particular, a build-up of snow or
mud on your vehicle's underside
adds weight and rolling resistance.
Frequent cleaning helps your fuel
economy.
Drive Efficiently●Drive moderately －Rapid
acceleration, abrupt cornering, and
hard braking increase fuel
consumption.●Observe the speed limit －
Aerodynamic drag has a big effect
on fuel economy at speeds above
45 mph (75 km/h). Reduce your
speed and you reduce the drag.
Trailers, car top carriers, roof
racks and bike racks are also big
contributors to increased drag.
