Child Restraint
Everyone in your vehicle needs to be buckled up all the
time, including babies and children. Every state in the
United States and all Canadian provinces require that
small children ride in proper restraint systems. This is the
law, and you can be prosecuted for ignoring it.
Children 12 years and younger should ride properly
buckled up in a rear seat, if available. According to crash
statistics, children are safer when properly restrained in
the rear seats rather than in the front.

22. Anti-Lock Brake System (ABS) Warning LightThis light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON position and may
stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the Brake System Warning Light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefit of Anti-Lock
brakes. Furthermore, the ABS light should be checked
frequently to assure that it is operating properly. If the
light does not turn on, have the system checked by an
authorized dealer. (See page 328 for more information.) 23. Electronic Stability Program (ESP)/Traction
Control System (TCS) Indicator Light
If this indicator light flashes during accelera-
tion, ease up on the accelerator and apply as
little throttle as possible. Adapt your speed and
driving to the prevailing road conditions. (See
page 328 for more information.)
24. Malfunction Indicator Light (MIL) This light is part of an Onboard Diagnostic
system called OBD II. The OBD system monitors
emissions, engine, and automatic transaxle con-
trol systems. The MIL will turn on when the key is in the
ON position before engine start. If the MIL does not turn
on when turning the key from LOCK or ACC to ON, have
the condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the MIL after
engine start. The vehicle should be serviced if the MIL

304 STARTING AND OPERATING

CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the power transfer unit.
DRIVING ON SLIPPERY SURFACES
ACCELERATION
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the front wheels to pull errati-
cally to the right or left. This phenomenon occurs when
there is a difference in the surface traction under the front
(driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the
front wheels. You could lose control of the vehicle
and possibly have an accident. Accelerate slowly and
carefully whenever there is likely to be poor traction
(ice, snow, wet, mud, loose sand, etc.).
TRACTION
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is hydroplaning and may cause partial or
complete loss of vehicle control and stopping ability. To
reduce this possibility, the following precautions should
be observed:
1. Slow down during rainstorms or when roads are
slushy.
320 STARTING AND OPERATING

Anti-Lock Brake System (ABS)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lock-up to
help avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System (ABS)” under “Elec-
tronic Brake Control System” in this section for more
information.
WARNING!
The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. ABS
cannot prevent accidents, including those resulting
from excessive speed in turns, driving on very slip-
pery surfaces, or hydroplaning. Only a safe, attentive,
and skillful driver can prevent accidents. The capa-
bilities of an ABS-equipped vehicle must never be
exploited in a reckless or dangerous manner, which
could jeopardize the user’s safety or the safety of
others.

ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system commonly referred to as ESP. This
system includes Anti-Lock Brake System (ABS), Brake
Assist System (BAS), Traction Control System (TCS), Elec-
tronic Roll Mitigation (ERM), and Electronic Stability Pro-
gram (ESP). These systems work together to enhance both
vehicle stability and control in various driving conditions.
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most
braking conditions. The system automatically “pumps”
the brakes during severe braking conditions to prevent
wheel lock-up.
When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as some
related motor noises. These noises are the system per-
forming its self check cycle to ensure that the ABS isworking properly. This self check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).
ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
You also may experience the following when the brake
system goes into Anti-lock:•The ABS motor running (it may continue to run for a
short time after the stop),
•The clicking sound of solenoid valves,
•Brake pedal pulsations, and
•A slight drop or fall away of the brake pedal at the end
of the stop.
These are all normal characteristics of ABS.
328 STARTING AND OPERATING

Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS functions similar to a
limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESP are in the
“Partial Off” mode. Refer to “ESP (Electronic Stability
Program)” in this section for more information.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the
speed of the vehicle. When ERM determines that the rate
of change of the steering wheel angle and vehicle’s speed
are sufficient to potentially cause wheel lift, it then
applies the appropriate brake and may also reduce
engine power to lessen the chance that wheel lift will
occur. ERM will only intervene during very severe or
evasive driving maneuvers. ERM can only reduce the
chance of wheel lift occurring during severe or evasive
driving maneuvers. It cannot prevent wheel lift due to
other factors, such as road conditions, leaving the road-
way, or striking objects or other vehicles.
STARTING AND OPERATING 331

WARNING!
Many factors, such as vehicle loading, road condi-
tions, and driving conditions, influence the chance
that wheel lift or rollover may occur. ERM cannot
prevent all wheel lift or rollovers, especially those
that involve leaving the roadway or striking objects
or other vehicles. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of an
ERM-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopar-
dize the user’s safety or the safety of others.
Electronic Stability Program (ESP)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESP cor-
rects for over-steering and under-steering the vehicle byapplying the brake of the appropriate wheel. Engine
power may also be reduced to help the vehicle maintain
the desired path.
The ESP uses sensors in the vehicle to determine the path
that the driver intends to steer the vehicle and compares
it to the actual path of the vehicle. When the actual path
does not match the intended path, the ESP applies the
brake of the appropriate wheel to assist in counteracting
the condition of over-steer or under-steer.
•Over-steer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Under-steer - when the vehicle is turning less than
appropriate for the steering wheel position.
ESP/TCS Indicator Light
The ESP/TCS Indicator Light located in the
instrument cluster, starts to flash as soon as the
tires lose traction and the ESP system becomes
332 STARTING AND OPERATING

active. The ESP/TCS Indicator Light also flashes when
TCS is active. If the ESP/TCS Indicator Light begins to
flash during acceleration, ease up on the accelerator and
apply as little throttle as possible. Be sure to adapt your
speed and driving to the prevailing road conditions.
WARNING!
ESP cannot prevent the natural laws of physics from
acting on the vehicle, nor can it increase the traction
afforded by prevailing road conditions. ESP cannot
prevent accidents, including those resulting from
excessive speed in turns, driving on very slippery
surfaces, or hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The capabilities
of an ESP-equipped vehicle must never be exploited
in a reckless or dangerous manner, which could
jeopardize the user’s safety or the safety of others.
ESP Operating Modes
The ESP system has two available operating modes.
Full On
This is the normal operating mode for ESP. Whenever the
vehicle is started the system will be in this mode. This
mode should be used for most driving situations. ESP
should only be turned to “Partial Off” for specific reasons
as noted. Refer to “Partial Off” for additional informa-
tion.
Partial Off
The ESP OFF button is located in the switch bank above
the climate Control. To enter the “Partial Off” mode,
momentarily depress the ESP OFF button and the ESP/
TCS Indicator Light will illuminate. To turn the ESP on
again, momentarily depress the ESP OFF button and the
ESP/TCS Indicator Light will turn off. This will restore
the normal “ESP On” mode of operation.

TIRE QUALITY GRADES
The following tire grading categories were established by
the National Highway Traffic Safety Administration. The
specific grade rating assigned by the tire’s manufacturer
in each category is shown on the sidewall of the tires on
your vehicle.
All passenger car tires must conform to Federal safety
requirements in addition to these grades.
Treadwear
The Treadwear grade is a comparative rating, based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and one-half
times as well on the government course as a tire graded
100. The relative performance of tires depends upon the
actual conditions of their use, however, and may depart
significantly from the norm due to variations in driving
habits, service practices, and differences in road charac-
teristics and climate.
Traction Grades
The Traction grades, from highest to lowest, are AA, A, B,
and C. These grades represent the tire’s ability to stop on
wet pavement, as measured under controlled conditions
on specified government test surfaces of asphalt and
concrete. A tire marked C may have poor traction perfor-
mance.
