The Active stability
control (ASC) takes
overall control of the
anti-lock braking sys-
tem, traction control function and skid controlfunction to help maintain the vehicle’s control and traction. Please read

junction with the page on the anti-lock brak-ing system, traction control function and skid control function. Anti-lock braking system

On slippery surfaces, the traction control function prevents the drive wheels from spin-
ning excessive, thus helping the vehicle to start moving from a stopp
ed condition.
It also
provides sufficient driv
ing force and steering
performance as the vehicle turns while press- ing the acceleration pedal.
N00559300051
The skid control function is designed to helpthe driver maintain control of the vehicle onslippery roads or during rapid steering maneuvers. It works by controlling the engine output and the brake on each wheel.

The ASC is automatically activated when theignition switch is turned to the “ON” position or the operation mode is put in ON. You can
Active stability control (ASC)
CAUTION Do not over-rely on the ASC. Even the ASC cannot prevent the natural laws of physicsfrom acting on the vehicle. This system, like any other system, has
limits and cannot help
you to maintain traction and control of thevehicle in all circumstances. Reckless driv- ing can lead to accidents. It is the driver’s responsibillty to drive carefully, This meanstaking into account the tr
affic, road and envi-
ronmental conditions. Be sure to use the same specified type and size of tire on all four wheels. Otherwise, the ASC may not work properly.
 Do not install any aftermarket limited slip differential (LSD) on your vehicle. The ASCmay stop functioning properly.NOTE
 An operating sound or vibration may be emitted from under the body in the followingsituations. The sound or
vibration is associ-
ated with checking th
e operations of the
ASC. At this time, you may feel a shockfrom under the body and the brake pedal if you depress it. These do
not indicate a mal-
function. • When the ignition switch is turned to the “ON” position or the operation mode is putin ON. • When the vehicle is driven for a while after the engine is turned on.
 When the ASC is acti
vated, you may feel a
vibration in the vehicle body or hear a whin- ing sound from the engine compartment. This indicates that the system is operatingnormally. It does not i
ndicate a malfunction.
 When the anti-lock braking system warning light is illuminated, the ASC is not active.

CAUTION
CAUTION When driving a vehicle on a snowy or icy road, be sure to install snow tires and drive the vehicle at moderate speeds.
Skid control function
NOTE
 The skid control function operates at speeds of about 9 mph (15 km/h) or higher.

deactivate the system
by pressing down the
“ASC OFF” switch for
3 seconds or longer.
When the ASC is deactivated, the indica- tor will turn on. To reactivate the ASC, momentarily press the “ASC OFF” switch; the indicator is turned off.

If an abnormal condition occurs in the sys- tem, the following i
ndicator will turn on.
CAUTIONFor safety reasons, the “ASC OFF” switch should be operated when your vehicle isstopped.  Be sure to keep the ASC on while driving in normal circumstances.NOTE
 Using the “ASC OFF” switch turns off both the stability control function and the traction control function.
 When moving out of mud, sand or fresh snow, pressing the accelerator pedal may notallow the engine speed to increase. In suchsituations, temporarily turning off ASC with the “ASC OFF” switch will make it easier to move out your vehicle.  If you continue to press the “ASC OFF” switch after the ASC is turned off, the “mis-taken operation
protection function” will
activate and
the ASC will turn back on.
ASC operation indicator or ASC OFF indicator
-
ASC operation indicator The indicator will blink when the ASC is operating.
-
ASC OFF indicator This indicator will turn on when the ASC is turned off with the “ASCOFF” switch.
CAUTION When indicator blinks, ASC is operating, which means that the road is slippery or that your vehicle’s wheels are beginning to slip. If this happens, drive slower with less accel-erator input.NOTE
NOTE
 The indicator may turn on when you start the engine. This means
that the battery volt-
age momentarily dropped when the enginewas started. It does not
indicate
a malfunc-
tion, provided that the display goes out immediately.  When a compact spare tire has been put on your vehicle, the grippi
ng ability of the tire
will be lower, making it more likely that the indicator will blink.

EXAMPLE: 95H Maximum load indicates the maximum load this tire is designed to carry.
Maximum Pressure indicates the maximum permissible cold tire
inflation pressure for
this tire. The TIN may be found on one or both sides of the tire but the da
te code may only be on
one side. Look for the TIN on the outboard side of tires as mounted
on the vehicle. If the
TIN is not found on the outboard side thenyou will find it on the inboard side of the tire. EXAMPLE: DOT MA L9 ABCD 1504
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specifiedgovernment test course
. For example, a tire
graded 150 would wear one and one-half (11/2) times as well on the government course
as a tire graded 100.
The relative performance
of tires depends upon the actual conditions oftheir use, however, and may depart signifi- cantly from the norm due to variations in driving habits, service practices and differ-ences in road characteristics and climate.

Speed symbol A symbol indicating the range of speeds at which a tire can carry a load corresponding to its load index under certain operating con- ditions. The maximum speed correspond-ing to the speed symbol should only be achieved under specified operating conditions.

The traction grades, from highest to lowest, are AA, A, B and C. Those grades representthe tire’s ability to
stop on wet pavement as
measured under controlled conditions on specified government te
st surfaces of asphalt
and concrete. A tire marked C may have poor traction performance. The temperature grades are A (the highest), B and C, representing the ti
re’s resistance to the
generation of heat and it
s ability to dissipate
heat when tested un
der controlled conditions
on a specified indoor
laboratory test wheel.
Sustained high temperature can cause the material of the tire to
degenerate and reduce
tire life, and excessive temperature can lead to sudden tire failure. The grade C corre- sponds to a level of
performance which all
passenger car tires must
meet under the Fed-
eral Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels ofperformance on the laboratory test wheel than the minimum required by law.

Proper tire inflation pre
ssure is essential for
the safe and satisfac
tory operation of your
vehicle. The wrong tire pressure will cause problems in three major areas:  Safety Too little pressure increases flexing in the tire and can cause tire failure. Too much pressure can cause a tire to lose its abilityto cushion shock. Objects on the road and potholes could then cause tire damage that may result in tire failure. Economy The wrong tire pressure can cause uneven wear patterns in the tire tread. These abnormal wear patterns will reduce the tread life, and the tire will have to bereplaced sooner. Too little pressure also
makes it harder for
the tire to roll, and this uses up more fuel. Ride comfort and vehicle stability The superior riding ex
perience built into
your vehicle partly depends on the correcttire pressure. Too much pressure gives an uncomfortable and ja
rring ride. Too little
pressure feels as if
your vehicle is slow to
respond. Unequal tire pressure
s can make steering
your vehicle uneven
and unpredictable.
The tire pressure for your vehicle under nor- mal driving conditions is listed on the placard attached to the driver’s door sill. (Refer to “Tire and loading information plac-ard” on page 11-3.)
The recommended infl
ation pressures under
normal driving conditions should be used forthe tires listed below. Tire pressures should be checked, and adjusted if necessary,
at least once a month.
Pressures should be checked more often whenever weather temperatures changeseverely, becaus
e tire pressures change with
outdoor temperatures. The pressures listed are always “cold inflation pressure”.Cold inflation pressure is measured after the vehicle has been parked
for at least three
hours or is driven less than 1 mile (1.6 km)after having been parked for three hours. Cold inflation pressure
must not go above the
maximum values molded into the tire side-wall. After driving se
veral miles, your tire
inflation pressure may increase 2 to 6 psi (14 to 41 kPa) from the cold inflation pressure.Do not let air out of the tires to get back to the
