Maintenance
Passenger Compartment Air Filter
The filter removes dust, pollen, and other
airborne irritants from outside air that is
pulled into the vehicle.
The filter should be replaced as part of
routine scheduled maintenance. To find out
what type of filter to use, seeMaintenance
Replacement Parts 0330.
1. Open the glove box.
2. Squeeze both sides of the glove box bin inward to lower beyond the stops.
3. Release the latches on either side of theservice door. Open the service door and
remove the old filter.
4. Install the new air filter. Ensure air filter orientation is correct.
5. Close the service door completely.
6. Reverse the steps to reinstall the glove box.
See your dealer if additional assistance is
needed.
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. See your dealer for service.

190 Driving and Operating
Driving for Better Fuel Economy
Driving habits can affect fuel mileage. Here
are some driving tips to get the best fuel
economy possible:
.Set the climate controls to the desired
temperature after the engine is started,
or turn them off when not required.
.Avoid fast starts and accelerate smoothly.
.Brake gradually and avoid abrupt stops.
.Avoid idling the engine for long periods
of time.
.When road and weather conditions are
appropriate, use cruise control.
.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 driving
defensively is to wear the seat belt. See
Seat Belts 042.

Driving and Operating 205
Parking over Things That Burn
{Warning
Things that can burn could touch hot
exhaust parts under the vehicle and
ignite. Do not park over papers, leaves,
dry grass, or other things that can burn.
Active Fuel Management
This vehicle's engine may be equipped with
Active Fuel Management, which allows the
engine to operate on either all of its
cylinders, or in reduced cylinder operation
mode, depending on the driving conditions.
When less power is required, such as
cruising at a constant vehicle speed, the
system will operate in reduced cylinder
operation mode, allowing the vehicle to
achieve better fuel economy. When greater
power demands are required, such as
accelerating from a stop, passing,
or merging onto a freeway, the system will
maintain full-cylinder operation. If the
vehicle has an Active Fuel Management
indicator, see Driver Information Center (DIC)
for more information on using this display.
Extended Parking
It is best not to park with the vehicle
running. If the vehicle is left running, be
sure it will not move and there is adequate
ventilation.
SeeShifting Into Park 0204 and
Engine Exhaust 0205.
If the vehicle is left parked and running with
the remote key outside the vehicle, it will
continue to run for up to 15 minutes.
If the vehicle is left parked and running with
the remote key inside the vehicle, it will
continue to run for up to 30 minutes.
The vehicle could turn off sooner if it is
parked on a hill, due to lack of
available fuel.
The timer will reset if the vehicle is taken
out of P (Park) while it is running.
Engine Exhaust
{
Warning
Engine exhaust contains carbon monoxide
(CO), which cannot be seen or smelled.
Exposure to CO can cause
unconsciousness and even death.
Exhaust may enter the vehicle if:
.The vehicle idles in areas with poor
ventilation (parking garages, tunnels,
deep snow that may block underbody
airflow or tail pipes).
.The exhaust smells or sounds strange
or different.
.The exhaust system leaks due to
corrosion or damage.
.The vehicle exhaust system has been
modified, damaged, or improperly
repaired.
.There are holes or openings in the
vehicle body from damage or
aftermarket modifications that are not
completely sealed. (Continued)

it is fully engaged.
The transmission does not operate when the
vehicle is off.
If the vehicle is in ACC/ACCESSORY, the
transmission can be shifted into P (Park).
If ENGINE START/STOP is pressed twice while
at a relatively high speed, the engine will
turn off and the transmission will automatically shift into N (Neutral). Once
the vehicle is stopped, P (Park) can be
selected.
P :
This position locks the drive wheels. Use
P (Park) when starting the vehicle to ensure
the vehicle does not move.
{Warning
It is dangerous to get out of the vehicle
if the transmission is not in P (Park) with
the parking brake set. The vehicle
can roll.
Do not leave the vehicle when the engine
is running. If the engine has been left
running, the vehicle can move suddenly.
You or others could be injured. To be
sure the vehicle will not move, even
when on fairly level ground, always set
the parking brake and place the

Weather Conditions Affecting ACC
System operation may be limited under
snow, heavy rain, or road spray conditions.
Accessory Installations and Vehicle
Modifications
Do not install or place any object around
the front camera windshield area that would
obstruct the front camera view.
Do not install objects on top of the vehicle
that overhang and obstruct the front
camera, such as a canoe, kayak, or other
items that can be transported on a roof rack
system. SeeRoof Rack System 080.
Do not modify the hood, headlamps, or fog
lamps, as this may limit the camera’s ability
to detect an object.
Cleaning the Sensing System
The camera sensor on the windshield ahead
of the rearview mirror and the radar sensors
on the front of the vehicle can become
blocked by snow, ice, dirt, mud, or debis.
These areas need to be cleaned for ACC to
operate properly. If ACC will not operate, regular cruise control
may be available. See
“Switching Between
ACC and Regular Cruise Control” in this
section. Always consider driving conditions
before using either cruise control system.
For cleaning instructions, see “Washing the
Vehicle” underExterior Care 0311.
Driver Assistance Systems
This vehicle may have features that work
together to help avoid crashes or reduce
crash damage while driving, backing, and
parking. Read this entire section before
using these systems.
{Warning
Do not rely on the Driver Assistance
Systems. These systems do not replace
the need for paying attention and driving
safely. You may not hear or feel alerts or
warnings provided by these systems.
Failure to use proper care when driving
may result in injury, death, or vehicle
damage. See Defensive Driving 0190.

disappears after a short period of time.
If the vehicle has a trailer hitch attached,
select ON - ATTACHED using the
infotainment system menus to allow Park
Assist to function properly. Park Assist is
able to compensate for a trailer hitch up to
0.3 m (1 ft) in length and width. Park Assist
may not function properly with larger trailer
hitches and provide inaccurate information
of objects in the rear.
Turn off Park Assist when towing a trailer to
prevent unwanted beeps and when a bike
rack is attached to ensure proper operation.
The Park Assist System can also be turned
on or off using the infotainment system.
SeeVehicle Personalization 0110.
When the System Does Not Seem to Work
Properly
If a service message displays, check the
following conditions:
.The sensors may not be clean. Keep the
vehicle's front and rear bumpers free of
mud, dirt, snow, ice, and slush. For
cleaning instructions, see Exterior Care
0 311.
.The Park Assist sensors may be covered
by frost or ice. Frost or ice can form
around and behind the sensors and may
not always be seen; this can occur after
washing the vehicle in cold weather. The
message may not clear until the frost or
ice has melted.
If a service message displays and the above
conditions do not exist, take the vehicle to
your dealer for repairs.
If the Park Assist System does not activate
due to a temporary condition, a system off
message is shown on the display. This can
occur under the following conditions:
.The driver has disabled the system.
.An object is currently blocking the rear
sensors (for example, bike rack, tailgate,
trailer hitch, etc.). Once the object is
removed, Park Assist will return to normal
operation.
.The bumper is damaged. Take the vehicle
to your dealer for repairs.
.Other conditions, such as vibrations from
a jackhammer or the compression of air
brakes on a very large truck, are affecting
system performance.
Automatic Parking Assist (APA)
Enhanced Automatic Parking Assist (APA)
If equipped, under certain conditions
Enhanced Automatic Parking Assist (APA) can
use sensors based on sonar technology
along the vehicle’s front, rear and sides to
detect a parking spot and automatically park
the vehicle. The vehicle will automatically
maneuver into a detected spot moving at or
near idle speed. It does this by
automatically steering, braking, accelerating,
and gear shifting. The driver must always be
prepared to apply braking if necessary. A
display and beeps help to guide the parking
maneuvers.
{Warning
APA may not always detect objects in the
parking space, objects that are not rigid
(e.g. shrubs and chain-link fences), objects
below the bumper, objects high off the
ground (e.g. flatbed trucks), hanging
objects, objects below ground level such
(e.g. large potholes), or moving objects
(e.g. pedestrians, cyclists, vehicles).
Always verify that the parking space is
appropriate for parking a vehicle. APA (Continued)

.The driver manually steers the vehicle.
.The maximum allowed speed is exceeded.
.There is a failure with the APA system.
.Electronic stability control or antilock
brakes are activated.
.The parking brake is applied or vehicle is
shifted into Park (P).
.Driver unbuckles seat belt and
opens door. System Limitations
Automatic Parking Assist has certain
limitations. The system cannot:
.The system cannot continue to operate if
the maneuver speed exceeds
5 km/h (3 mph).
.Detect whether a parking space is legal or
restricted.
.Detect pavement markings or lines
.Park the vehicle closely lined up with the
vehicle next to it, particularly if the spot
is approached at an angle or if the
parking space is angled.
.Park exactly centered in a very large spot.
.Always detect short curbs.
.Operate while towing any trailer.
.Function the vehicle is raised or lowered
by air suspension (if equipped).
.Detect or automatically react to
approaching traffic when exiting a
