brake Acura RDX 2012 Workshop Manual

The reading of the vehicle's
temperature gauge on the multi-
information display 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 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 from under the hood.
Driving with the temperature gauge
reading at the H (Hot) mark can cause
serious damage to the engine.
Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
1. Safely pull to the side of the road. Put the transmission in Park, and
set the parking brake. Turn off all
accessories, and turn on the
hazard warning lights. 2. If you see steam and/or spray
coming from under the hood, turn
off the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
3. 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.
4. If the temperature gauge reading stays at the H (Hot) mark, turn off
the engine.

Brake System Indicator
(Red)U.S. CanadaThe brake system indicator (red)
normally comes on when you turn
the ignition switch to the ON (II)
position, and as a reminder to check
the parking brake. It will stay on if
you do not fully release the parking
brake.
If the brake system indicator (red)
comes on while driving, the brake
fluid level is probably low. Press
lightly on the brake pedal to see if it
feels normal. If it does, check the
brake fluid level the next time you
stop at a service station (see page
429).
You will also see a‘‘BRAKE FLUID
LOW ’’message on the multi-
information display (see page 79). If the fluid level is low, take your
vehicle to a dealer, and have the
brake system inspected for leaks or
worn brake pads.
However, if the brake pedal does not
feel normal, you should take
immediate action. A problem in one
part of the system's dual circuit
design will still give you braking at
two wheels. You will feel the brake
pedal go down much farther before
the vehicle begins to slow down, and
you will have to press harder on the
pedal.
You will also see a
‘‘CHECK BRAKE
SYSTEM ’’message on the multi-
information display (see page 79). Slow down by shifting to a lower
gear, and pull to the side of the road
when it is safe. Because of the long
distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed, and repaired as
soon as possible (see
Emergency
Towing on page 475).
If you must drive the vehicle a short
distance in this condition, drive
slowly and carefully.
If the ABS indicator and the VSA
system indicator come on with the
brake system indicator, have your
vehicle inspected by your dealer
immediately.

Brake System Indicator
(Amber)U.S. CanadaYour vehicle has an electric vacuum
pump located in the engine
compartment. It enhances the
effectiveness of your vehicle'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 normally
comes on when you turn the ignition
switch to the ON (II) position and
goes off after the engine starts. If it
comes on at any other time, 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-
information display (see page 79).Brake System Indicator46811/06/16 17:42:51 12 ACURA RDX MMC North America Owner's M 50 31STK650 enu

If your vehicle needs to be towed,
call a professional towing service or
organization. Never tow your vehicle
with just a rope or chain. It is very
dangerous.(On SH-AWD models)The only way you can safely tow
your vehicle is with flat-bed
equipment.The operator will load
your vehicle on the back of a truck.
Any other method of towing will
damage the drive system. When you
contact the towing agency, inform
them a flat-bed is required.Towing with only two tires on the
ground will damage parts of the all-
wheel-drive system. Your vehicle should
be transported on a flat-bed truck or
trailer.
(Execpt SH-AWD models)There are two ways to tow your
vehicle:Flat-bed Equipment
－ The operator
loads your vehicle on the back of a
truck. This is the best way to
transport your vehicle.
Wheel-lift Equipment
－ The tow
truck uses two pivoting arms that go
under the front tires and lift them off
the ground. The rear tires remain on
the ground. This is an acceptable
way to tow your vehicle. If, due to damage, your vehicle must
be towed with the front wheels on
the ground, do this:
●Start the engine.●Shift to the D position and hold for
5 seconds, then to N.●Turn off the engine.●Leave the ignition switch in the
ACCESSORY (I) position so the
steering wheel does not lock.●Release the parking brake.

8. Select a nearby lightly traveledmajor highway where you can
maintain a speed of 50 to 60 mph
(80 to 100 km/h) for at least 20
minutes. Drive on the highway in
D. Do not use the cruise control.
When traffic allows, drive for 90
seconds without moving the
accelerator pedal. (Vehicle speed
may vary slightly; this is okay.) If
you cannot do this for a continuous
90 seconds because of traffic
conditions, drive for at least 30
seconds, then repeat it two more
times (for a total of 90 seconds). 9. Then drive in city/suburban traffic
for at least 10 minutes. When
traffic conditions allow, let the
vehicle coast for several seconds
without using the accelerator pedal
or the brake pedal.
10. Make sure the vehicle has been parked with the engine off for 30
minutes.
If the testing facility determines the
readiness codes are still not set, see
your dealer.
