.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
0 256.
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.
If stuck too severely for the
traction system to free the
vehicle, turn the traction
system off and use the rocking
method. See Traction Control/
Electronic Stability Control

267.
{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).
For All-Wheel Drive (AWD),
select Off-Road or AWD mode.
See Driver Mode Control
0 269 and
All-Wheel Drive 0263.
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
the transmission is in gear.
Slowly spinning the wheels in

the vehicle before shifting to
P (Park). The vehicle may
restart and move
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 0122.
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 Starts 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 0269.
.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 pressing
h.
Auto Stop/Start is enabled
each time you start the
vehicle.

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
Braking (FPB)
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.
(Continued)
Warning (Continued)
.Adjust the climate control
system to a setting that
brings in only outside air.
See“Climate Control
Systems” in the Index.
For more information about
carbon monoxide, see
Engine Exhaust 0256.
Towing a trailer requires
experience. The combination
of the vehicle and trailer is
longer and not as responsive
as the vehicle itself. Become
familiar to the handling and
braking by driving on a level
road surface before driving on
public roads.
The trailer structure, the tires,
and the brakes must be all be
rated to carry the intended
cargo. Inadequate trailer
equipment can cause the
combination to operate in an
unexpected or unsafe manner.
Before driving, inspect all
trailer hitch parts and

Quality grades can be
found where applicable on
the tire sidewall between
tread shoulder and
maximum section width.
For example:
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 tiresdepends 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
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
