.Always follow posted speed
limits or drive more slowly
when conditions require.
.Keep vehicle tires properly
inflated.
.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
section 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

Warning (Continued)
If the vehicle is stuck
in snow:
.Clear snow from the base
of the vehicle, especially
any blocking the
exhaust pipe.
.Open a window about
5 cm (2 in) on the vehicle
side that is away from the
wind, to bring in fresh air.
.Fully open the air outlets
on or under the
instrument panel.
.Adjust the climate control
system to circulate the air
inside the vehicle and set
the fan speed to the
highest setting. See
“Climate Control Systems.”
For more information about
CO, see Engine Exhaust
0 265.
To save fuel, run the engine
for short periods to warm the
vehicle and then shut the engine off and partially close
the window. Moving about to
keep warm also helps.
If it takes time for help to
arrive, when running the
engine, push the accelerator
pedal slightly so the engine
runs faster than the idle
speed. This keeps the battery
charged to restart the vehicle
and to signal for help with the
headlamps. Do this as little as
possible, to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle
when stuck in sand, mud, ice,
or snow.
The Traction Control System
(TCS) can often help to free a
stuck vehicle. See Traction
Control/Electronic Stability
Control
0276.
If TCS cannot free the vehicle,
turn TCS off and use the
rocking method. See “Rocking
the Vehicle to Get it Out”
following.
{Warning
If the vehicle's tires spin at
high speed, they can
explode, and you or others
could be injured. The vehicle
can overheat, causing an
engine compartment fire or
other damage. Spin the
wheels as little as possible
and avoid going above
56 km/h (35 mph).
Rocking the Vehicle to Get
it Out
Turn the steering wheel left
and right to clear the area
around the front wheels. Turn
off any traction system. Shift
back and forth between
R (Reverse) and a low forward
gear, spinning the wheels as
little as possible. To prevent
transmission wear, wait until
the wheels stop spinning
before shifting gears. Release
the accelerator pedal while
shifting, and press lightly on
the accelerator pedal when

Warning (Continued)
unexpectedly. Always shift
to P (Park), and then turn
the ignition off before
exiting the vehicle.
Auto Engine Stop/Start
When the brakes are applied
and the vehicle is at a
complete stop, the engine may
turn off. When stopped, the
tachometer displays AUTO
STOP. See Tachometer 0130.
When the brake pedal is
released or the accelerator
pedal is pressed, the engine
will restart.
To maintain vehicle
performance, other conditions
may cause the engine to
automatically restart before
the brake pedal is released.
Auto Stops may not occur
and/or auto restarts may
occur because:
.The climate control settings
require the engine to be
running to cool or heat the
vehicle interior.
.The vehicle battery needs to
charge.
.The vehicle battery has
recently been disconnected.
.Minimum vehicle speed has
not been reached since the
last Auto Stop.
.The accelerator pedal is
pressed.
.The engine or transmission
is not at the required
operating temperature.
.The outside temperature is
not in the required operating
range.
.The vehicle transmission is
shifted out of D (Drive) to
any gear other than P (Park).
.Certain driver modes have
been selected. See Driver
Mode Control 0278.
.The vehicle is on a steep hill
or grade.
.The driver door has been
opened or the driver seat
belt has been unbuckled.
.The hood has been opened.
.The Auto Stop has reached
the maximum allowed time.
Auto Stop Disable Switch
The automatic engine Stop/
Start feature can be disabled
and enabled by touching the
hsymbol. Auto Stop is
enabled each time you start
the vehicle.

trailer towing.
.Vehicles can tow in D (Drive).
If the transmission
downshifts too often, a
lower gear may be selected
using Manual Mode. See
Manual Mode0271.
If equipped, the following
driver assistance features
should be turned off when
towing a trailer:
.Adaptive Cruise
Control (ACC)
.Super Cruise Control
.Park Assist
.Automatic Parking
Assist (APA)
.Reverse Automatic
Braking (RAB)
If equipped, the following
driver assistance features
should be turned to alert or
off when towing a trailer:
.Automatic Emergency
Braking (AEB)
.Intelligent Brake Assist (IBA)
.Front Pedestrian

If equipped with Lane Change
Alert (LCA), the LCA detection
zones that extend back from
the side of the vehicle do not
move further back when a
trailer is towed. Use caution
while changing lanes when
towing a trailer.
If equipped with Rear Cross
Traffic Alert (RCTA), use
caution while backing up when
towing a trailer, as the RCTA
detection zones that extend out from the back of the
vehicle do not move further
back when a trailer is towed.
{Warning
To prevent serious injury or
death from carbon monoxide
(CO), when towing a trailer:
.Do not drive with the
liftgate, trunk/hatch,
or rear-most
window open.
.Fully open the air outlets
on or under the
instrument panel.
.Adjust the climate control
system to a setting that
brings in only outside air.

422 Vehicle Care
Treadwear 200 Traction AA
Temperature A
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 (1½) 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 drivinghabits, service practices
and differences in road
characteristics and climate.
Traction
The traction grades, from
highest to lowest, are AA,
A, B, and C. Those 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
performance. Warning: The
traction grade assigned to
this tire is based on
straight-ahead braking
traction tests, and does not
include acceleration,
cornering, hydroplaning,
or peak traction
characteristics.
Temperature
The temperature grades
are A (the highest), B, and
C, representing the tire's
resistance to the
generation of heat and its
ability to dissipate heat
when tested under
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 corresponds to a
level of performance which
all passenger car tires must
meet under the Federal
Motor Safety Standard
No. 109. Grades B and A
represent higher levels of
performance on the
laboratory test wheel than
the minimum required by
