cruise control Acura RL 2007 Owner's Guide

With ACC on, the distance between
your vehicle and the vehic le ahead of
you is controlled and maintained.
You can change this distance to one
of three ranges: long, middle, or
short. To
change the range, press the
DISTANCE button. Each time you
press the button, the range changes
from Long, to Middle, and then to
Short.
The higher your vehicle speed is, the
longer the distan ce between the
vehicle in front will be set as shown
below.
When that vehicle changes lanes or
goes out of ACC range, a beeper
sounds once. If there is no vehicle
ahead of you within ACC range, a
dotted-line vehicle icon will be on the
multi-inf ormation display.

while this indicator is on.
When
ACC is automatically
cancelled, the beeper sounds three
times, and an ACC OFF message
appears on the multi-info rmation
display for 3 seconds.
Any of these conditions may cause
ACC to cancel:

below22mph(35km/h). Driving
on a mountainous road, or
driving off road for extended
periods.

When
the ABS or VSA is activated.
Abrupt
steering wheel movement.
If ACC is cancelled by any these
conditions, wait until the condition
improves, then press the RES/
ACCEL button to restore ACC.
When you do this, the vehicle will

Frequent cleaning helps your f uel

Each torque indicator is displayed
as a bar graph divided into 5
segments. The number of
segments represents the amount
of torque distributed to each
wheel.
The SH-AWD torque distribution
monitor on the multi-inf ormation
display shows you the amount of
torque being sent to the wheels.
Each wheel: right f ront (RF), lef t
front(LF),rightrear(RR),andleft
rear (LR), has its own torque
indicator. When cruise control is on while
driving, the torque distribution
monitor is not shown.
The SH-AWD system is a full time
all-wheel-drive system that
automatically controls and transfers
varying amounts of engine torque to
all wheels independently, according
to the driving conditions.
When there is only a slight change in
torque distribution while driving,
such as cruising on level roads at the
same speed, the torque distribution
monitor may stop displaying the
amount of torque. This is not a
system problem. The monitor will
show the amount if the system
senses any change in torque
distribution.
While the SH-AWD system helps to
enhance the vehicle’s driving
stability in all situations, it is still
your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.

If one or more tires have low
pressure, the low tire pressure
indicator on the instrument panel
also comes on (see page ).
When cruise control is on while
driving, the pressure reading cannot
be checked by the tire pressure
monitor on the multi-inf ormation
display.
If the low tire pressure indicator and
the low tire position on the low tire
pressure monitor do not go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible.
When the TPMS is functioning
normally, you can see the tire
pressure readings of each tire in psi
(U.S. models) or kPa (Canadian
models) by pressing the SEL/
RESET button while the multi-
inf ormation display shows the tire
pressure monitor. 365

Select a nearby lightly traveled
major highway where you can
maintain a speed of 50 to 60 mph
f or at least 20 minutes. Drive on
the highway in D. Do not use the
cruise control. When traf f ic allows,
drive f or 90 seconds without
moving the accelerator pedal.
(Vehicle speed may vary slightly;
this is okay.) If you cannot do this
f or a continuous 90 seconds
because of traf f ic conditions, drive
f or at least 30 seconds, then repeat
it two more times (f or a total of 90
seconds).
