For persons under 21, it is against the law in every
U.S. state to drink alcohol. There are good medical,
psychological, and developmental reasons for
these laws.
The obvious way to eliminate the leading highway
safety problem is for people never to drink alcohol
and then drive.
Medical research shows that alcohol in a person's
system can make crash injuries worse, especially
injuries to the brain, spinal cord, or heart. This means
that when anyone who has been drinking—driver or
passenger —is in a crash, that person's chance of
being killed or permanently disabled is higher than if
the person had not been drinking.
Control of a Vehicle
The following three systems help to control the vehicle
while driving —brakes, steering, and accelerator. At
times, as when driving on snow or ice, it is easy to ask
more of those control systems than the tires and road
can provide. Meaning, you can lose control of the
vehicle. See Traction Control System (TCS)
on
page 5‑9, Enhanced Traction System (ETS)on
page 5‑11, and Electronic Stability Control (ESC)on
page 5‑6.
Adding non‐dealer/non‐retailer accessories can affect
vehicle performance. See Accessories and
Modifications on page 6‑3.
Braking
See Brake System Warning Light on page 4‑30.
Braking action involves perception time and reaction
time. Deciding to push the brake pedal is perception
time. Actually doing it is reaction time.
Average reaction time is about three‐fourths of a
second. But that is only an average. It might be less
with one driver and as long as two or three seconds or
more with another. Age, physical condition, alertness,
coordination, and eyesight all play a part. So do alcohol,
drugs, and frustration. But even in three‐fourths of a
second, a vehicle moving at 100 km/h (60 mph) travels
20 m (66 feet). That could be a lot of distance in an
emergency, so keeping enough space between the
vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement or
gravel; the condition of the road, whether it is wet, dry,
or icy; tire tread; the condition of the brakes; the weight
of the vehicle; and the amount of brake force applied.

Brake Assist
If this vehicle has ESC with ABS, it also has a Brake
Assist feature designed to assist the driver in stopping
or decreasing vehicle speed in emergency driving
conditions. This feature uses the stability system
hydraulic brake control module to supplement the power
brake system under conditions where the driver has
quickly and forcefully applied the brake pedal in an
attempt to quickly stop or slow down the vehicle. The
stability system hydraulic brake control module
increases brake pressure at each corner of the vehicle
until the ABS activates. Minor brake pedal pulsations or
pedal movement during this time is normal and the
driver should continue to apply the brake pedal as the
driving situation dictates The Brake Assist feature will
automatically disengage when the brake pedal is
released or brake pedal pressure is quickly decreased.
Electronic Stability Control (ESC)
The vehicle has an Electronic Stability Control (ESC)
system which combines antilock brake, and traction and
stability control systems that help the driver maintain
directional control of the vehicle in most driving
conditions.
When the vehicle is started and begins to move, the
system performs several diagnostic checks to ensure
there are no problems. The system may be heard or felt
while it is working. This is normal and does not mean
there is a problem with the vehicle. The system should
initialize before the vehicle reaches 20 mph (32 km/h).
If the system fails to turn on or activate, the ESC/TCS
light comes on, and the ESC OFF and/or SERVICE
ESC message displays.
For more information, seeDriver Information Center
(DIC)
on page 4‑46and Electronic Stability Control
(ESC)/Traction Control System (TCS) Indicator/Warning
Light on page 4‑33.

This light flashes on the
instrument panel cluster
when the ESC system is
on and activated.
ESC activates when the computer senses a
discrepancy between the intended path and the
direction the vehicle is actually traveling. ESC
selectively applies braking pressure at any one of the
vehicle's brakes to help steer the vehicle in the intended
direction.
When the system activates, an ESC ACTIVE message
displays on the Driver Information Center. See DIC
Warnings and Messages
on page 4‑48. This light also
flashes on the instrument panel cluster when the ESC
system is on and activated. Noise or vibration may be
felt in the brake pedal. This is normal. Continue to steer
the vehicle in the desired direction.
When the light is on solid and the message(s),
SERVICE ESC, ESC OFF, or both display, the system
will not assist the driver in maintaining directional
control of the vehicle. Adjust your driving accordingly.
See DIC Warnings and Messages on page 4‑48. The Electronic Stability Control (ESC) system is
automatically enabled whenever the vehicle is started.
To assist the driver with vehicle directional control,
especially in slippery road conditions, always leave the
system on. ESC can be turned off if needed.
If the vehicle is in cruise control when the system
begins to assist the driver maintain directional control of
the vehicle, the ESC/TCS light will flash and the cruise
control will automatically disengage. The cruise control
can be re-engaged when road conditions allow. See
Cruise Control on page 4‑8.
The ESC/TCS button is
located on the instrument
panel.
The traction control system can be turned off or back
on by pressing the ESC/TCS button. To disable both
traction control and ESC, press and hold the button
from five to ten seconds.
