104 INSTRUMENTS AND CONTROLS
This light flashes amber as a Lane
Departure Warning (LDW) alert, to
indicate that the lane marking has
been crossed.
LKA will not assist or alert if the turn
signal is active in the direction of lane
departure, or if LKA detects that you
are accelerating, braking, or actively
steering.
SeeLane Keep Assist (LKA) 0219.
Vehicle Ahead Indicator
If equipped, this indicator will display
green when a vehicle is detected
ahead and amber when you are
following a vehicle ahead much too
closely.
See Forward Collision Alert (FCA)
System 0211.
Pedestrian Ahead Indicator
If equipped, this indicator will display
amber when a nearby pedestrian is
detected in front of the vehicle.
See Front Pedestrian Braking (FPB)
System 0214.
Traction Off Light
This light comes on briefly while
starting the engine. If it does not,
have the vehicle serviced by your
dealer. If the system is working
normally, the indicator light then
turns off. The traction off light comes on when
the Traction Control System (TCS) has
been turned off by pressing and
releasing the TCS/StabiliTrak/
Electronic Stability Control (ESC)
button.
This light and the StabiliTrak OFF
light come on when StabiliTrak/ESC is
turned off.
If the TCS is off, wheel speed will be
limited when necessary to protect the
driveline from damage. Adjust driving
accordingly.
See
Traction Control/Electronic Stability
Control 0182.
StabiliTrak OFF Light
This light comes on briefly while
starting the engine. If it does not,
have the vehicle serviced by your
dealer.

INSTRUMENTS AND CONTROLS 105
This light comes on when the
StabiliTrak/Electronic Stability Control
(ESC) system is turned off.
If StabiliTrak/ESC is off, the Traction
Control System (TCS) is also off.
If StabiliTrak/ESC and TCS are off, the
system does not assist in controlling
the vehicle. Turn on the TCS and the
StabiliTrak/ESC systems, and the
warning light turns off.
SeeTraction Control/Electronic Stability
Control 0182.
Traction Control System
(TCS)/StabiliTrak Light
This light comes on briefly when the
engine is started.
If the light does not come on, have
the vehicle serviced by your dealer.
If the system is working normally, the
indicator light turns off. If the light is on and not flashing, the
TCS and potentially the StabiliTrak/
ESC system have been disabled.
A Driver Information Center (DIC)
message may display. Check the DIC
messages to determine which
feature(s) is no longer functioning and
whether the vehicle requires service.
If the light is on and flashing, the TCS
and/or the StabiliTrak/ESC system is
actively working.
See
Traction Control/Electronic Stability
Control 0182.
Engine Coolant
Temperature Warning Light
On some vehicles this light comes on
briefly while starting the vehicle. If it
does not, have the vehicle serviced by
the dealer. If the system is working
normally the indicator light goes off. For vehicles with the reconfigurable
cluster, this light may not come on
when starting the vehicle.
Caution
The engine coolant temperature
warning light indicates that the
vehicle has overheated. Driving with
this light on can damage the engine
and it may not be covered by the
vehicle warranty. See
Engine
Overheating 0250.
The engine coolant temperature
warning light comes on when the
engine has overheated.
If this happens pull over and turn off
the engine as soon as possible. See
Engine Overheating 0250.

DRIVING AND OPERATING 143
.Combine several trips into a
single trip.
. Replace the vehicle's tires with the
same TPC Spec number molded
into the tire's sidewall near
the size.
. Follow recommended scheduled
maintenance.
Distracted Driving
Distraction comes in many forms and
can take your focus from the task of
driving. Exercise good judgment and
do not let other activities divert your
attention away from the road. Many
local governments have enacted laws
regarding driver distraction. Become
familiar with the local laws in
your area.
To avoid distracted driving, keep your
eyes on the road, keep your hands on
the steering wheel, and focus your
attention on driving.
.Do not use a phone in demanding
driving situations. Use a
hands-free method to place or
receive necessary phone calls. .
Watch the road. Do not read, take
notes, or look up information on
phones or other electronic devices.
. Designate a front seat passenger
to handle potential distractions.
. Become familiar with vehicle
features before driving, such as
programming favorite radio
stations and adjusting climate
control and seat settings. Program
all trip information into any
navigation device prior to driving.
. Wait until the vehicle is parked to
retrieve items that have fallen to
the floor.
. Stop or park the vehicle to tend to
children.
. Keep pets in an appropriate carrier
or restraint.
. Avoid stressful conversations
while driving, whether with a
passenger or on a cell phone.
{Warning
Taking your eyes off the road too
long or too often could cause a
crash resulting in injury or death.
Focus your attention on driving.
Refer to the infotainment manual for
more information on using that
system and the navigation system,
if equipped, including pairing and
using a cell phone.
Defensive Driving
Defensive driving means “always
expect the unexpected.” The first step
in driving defensively is to wear the
seat belt. See Seat Belts044.
. Assume that other road users
(pedestrians, bicyclists, and other
drivers) are going to be careless
and make mistakes. Anticipate
what they may do and be ready.
. Allow enough following distance
between you and the driver in
front of you.
. Focus on the task of driving.

146 DRIVING AND OPERATING
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.
. Steering or Cornering Skid —too
much speed or steering in a curve
causes tires to slip and lose
cornering force.
. Acceleration Skid —too much
throttle causes the driving wheels
to spin.
Defensive drivers avoid most skids by
taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible.
If the vehicle starts to slide, follow
these suggestions:
. Ease your foot off the accelerator
pedal and steer the way you want
the vehicle to go. The vehicle may
straighten out. Be ready for a
second skid if it occurs. .
Slow down and adjust your driving
according to weather conditions.
Stopping distance can be longer
and vehicle control can be affected
when traction is reduced by water,
snow, ice, gravel, or other material
on the road. Learn to recognize
warning clues —such as enough
water, ice, or packed snow on the
road to make a mirrored surface
— and slow down when you have
any doubt.
. Try to avoid sudden steering,
acceleration, or braking, including
reducing vehicle speed by shifting
to a lower gear. Any sudden
changes could cause the tires to
slide.
Remember: Antilock brakes help avoid
only the braking skid.
Track Events and
Competitive Driving
(V-Series Only)
{Danger
High-performance features are
intended for use only on closed
tracks by experienced and qualified
drivers and should not be used on
public roads. High-speed driving,
aggressive cornering, hard braking,
and other high-performance driving
can be dangerous. Improper driver
inputs for the conditions may result
in loss of control of the vehicle,
which could injure or kill you or
others. Always drive safely.
Track events and competitive driving
may affect the vehicle warranty. See
the warranty manual before using the
vehicle for competitive driving.
