Maintenance
Passenger
Compartment Air
Filter
The filter reduces dust, pollen,
and other airborne irritants
from outside air that is pulled
into the vehicle. The filtershould be replaced as part of
routine scheduled
maintenance. See
Maintenance Schedule
0454.
See your dealer regarding
replacement of the filter.
Service
All vehicles have a label
underhood that identifies the
refrigerant used in the vehicle.
The refrigerant system should
only be serviced by trained
and certified technicians. The
air conditioning evaporator
should never be repaired or
replaced by one from a
salvage vehicle. It should only
be replaced by a new
evaporator to ensure proper
and safe operation.
During service, all refrigerants
should be reclaimed with
proper equipment. Venting
refrigerants directly to the
atmosphere is harmful to the
environment and may also
create unsafe conditions based on inhalation,
combustion, frostbite, or other
health-based concerns.
The air conditioning system
requires periodic maintenance.

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

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.
