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.

{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 044.
.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.
Impaired Driving
Death and injury associated with impaired
driving is a global tragedy.

Driving and Operating 193
Stopping the Engine/Off (No Indicator
Lights)
When the vehicle is stopped, press ENGINE
START/STOP once to turn the engine off.
To shift out of P (Park), the vehicle must be
on and the brake pedal must be applied.
If the vehicle is in P (Park), the ignition will
turn off, and Retained Accessory Power
(RAP) will remain active. SeeRetained
Accessory Power (RAP) 0199
If the vehicle is not in P (Park), the ignition
will return to ACC/ACCESSORY and display
the message SHIFT TO PARK in the Driver
Information Center (DIC).
When the vehicle is shifted into P (Park), the
ignition system will turn off.
The vehicle may have an electric steering
column lock. The lock is activated when the
vehicle is turned off and either front door is
opened. A sound may be heard as the lock
actuates or releases. The steering column
lock may not release with the wheels turned
off center. If this happens, the vehicle may
not start. Move the steering wheel from left
to right while attempting to start the
vehicle. If this does not work, the vehicle
needs service. Do not turn the engine off when the vehicle
is moving. This will cause a loss of power
assist in the brake and steering systems and
disable the airbags.
If the vehicle must be turned off in an
emergency:
1. Brake using a firm and steady pressure. Do not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving.
After shifting to N (Neutral), firmly apply
the brakes and steer the vehicle to a
safe location.
3. Come to a complete stop. Shift to P (Park) and turn the ignition off.
4. Set the electric parking brake. See Electric
Parking Brake 0205
{Warning
Turning off the vehicle while moving may
cause loss of power assist in the brake
and steering systems and disable the
airbags. While driving, only shut the
vehicle off in an emergency. If the vehicle cannot be pulled over and
must be turned off while driving, press and
hold ENGINE START/ STOP for longer than
two seconds, or press twice in five seconds.
ACC/ACCESSORY (Amber Indicator Light)
This mode allows you to use some electrical
accessories when the engine is off.
With the ignition off, pressing the button
one time without the brake pedal applied
will place the ignition system in ACC/
ACCESSORY.
The ignition will switch from ACC/
ACCESSORY to OFF after five minutes to
prevent battery rundown.
ON/RUN/START (Green Indicator Light)
This mode is for driving and starting. With
the ignition off and the brake pedal applied,
pressing the button once will place the
ignition system in ON/RUN/START. Once
engine cranking begins, release the button.
Engine cranking will continue until the
engine starts. See
Starting the Engine 0194.
The ignition will then remain in ON/RUN.

194 Driving and Operating
Service Mode
This power mode is available for service and
diagnostics, and to verify the proper
operation of the malfunction indicator lamp
as may be required for emission inspection
purposes. With the vehicle off and the brake
pedal not applied, pressing and holding the
button for more than five seconds will place
the vehicle in Service Mode. The instruments
and audio systems will operate as they do
in ON/RUN, but the vehicle will not be able
to be driven. The engine will not start in
Service Mode. Press the button again to turn
the vehicle off.
Starting the Engine
Move the shift lever to P (Park) or
N (Neutral). The engine will not start in any
other position. To restart the engine when
the vehicle is already moving, use
N (Neutral) only.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you could
damage the transmission. Shift to P (Park)
only when the vehicle is stopped.
Caution
If you add electrical parts or accessories,
you could change the way the engine
operates. Any resulting damage would
not be covered by the vehicle warranty.
SeeAdd-On Electrical Equipment 0241.
Starting Procedure (Key Access)
1. With your foot off the accelerator pedal,
turn the ignition key to START. When
the engine starts, let go of the ignition.
The idle speed will go down as the
engine gets warm. Do not race the
engine immediately after starting it.
Operate the engine and transmission
gently to allow the oil to warm up and
lubricate all moving parts.
Caution
Cranking the engine for long periods of
time, by returning the ignition to the
START position immediately after
cranking has ended, can overheat and
damage the cranking motor, and drain
the battery. Wait at least 15 seconds
between each try, to let the cranking
motor cool down. 2. If the engine does not start after five to
10 seconds, especially in very cold
weather (below −18 °C or 0 °F), it could
be flooded with too much gasoline. Try
pushing the accelerator pedal all the way
to the floor and holding it there as you
hold the key in START for up to a
maximum of 15 seconds. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down. When
the engine starts, let go of the key and
the accelerator. If the vehicle starts
briefly but then stops again, do the
same thing. This clears the extra gasoline
from the engine.
Do not race the engine immediately
after starting it.
Operate the engine and transmission
gently until the oil warms up and
lubricates all moving parts.Starting Procedure (Keyless Access)
1. With the Keyless Access system, the Remote Keyless Entry (RKE) transmitter
must be in the vehicle. Press ENGINE
START/STOP with the brake pedal
applied. When the engine begins
cranking, let go of the button.

14400528) - 2021 - CRC - 11/7/19
204 Driving and Operating
Press the AWD switch on the center console
to activate the system. The AWD light will
flash briefly while the system is engaging
and stay lit to indicate AWD is active. Press
the switch again to disable the system. The
light will flash briefly while the system
disables and then stay off.
The AWD Mode will stay selected until the
mode is changed.
When operated in two-wheel drive, the
vehicle will deliver power to the front
wheels only and may provide better fuel
economy.
When using a compact spare tire on an
AWD vehicle, the system automatically
detects the compact spare and reduces AWDperformance to protect the system. To
restore full AWD operation and prevent
excessive wear on the system, replace the
compact spare with a full-size tire as soon as
possible. See
Compact Spare Tire 0301.
Brakes
Electric Brake Boost
Vehicles equipped with electric brake boost
have hydraulic brake circuits that are
electronically controlled when the brake
pedal is applied during normal operation.
The system performs routine tests and turns
off within a few minutes after the vehicle is
turned off. Noise may be heard during this
time. If the brake pedal is pressed during
the tests or when the electric brake boost
system is off, a noticeable change in pedal
force and travel may be felt. This is normal.
Antilock Brake System (ABS)
The Antilock Brake System (ABS) helps
prevent a braking skid and maintain steering
while braking hard. ABS performs a system check when the
vehicle is first driven. A momentary motor
or clicking noise may be heard while this
test is going on, and the brake pedal may
move slightly. This is normal.
If there is a problem with ABS, this warning
light stays on. See
Antilock Brake System
(ABS) Warning Light 099.
ABS does not change the time needed to
get a foot on the brake pedal and does not
always decrease stopping distance. If you
get too close to the vehicle ahead, there will
not be enough time to apply the brakes if
that vehicle suddenly slows or stops. Always
leave enough room ahead to stop, even
with ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down firmly. Hearing or feeling ABS
operate is normal.

Driving and Operating 209
Sport Mode
Use Sport Mode where road conditions or
personal preference demand a more
controlled response. Sport Mode improves
vehicle handling and acceleration on dry
pavement. When active, Sport Mode
modifies steering efforts, transmission
shifting, and suspension tuning, if equipped.
Snow/Ice Mode (FWD Vehicles Only)
Snow/Ice Mode improves vehicle
acceleration on snow and ice covered roads.
When active, Snow/Ice Mode will adjust
acceleration to optimize traction on slippery
surfaces. This mode can compromise the
acceleration on dry asphalt.
This feature is not intended for use when
the vehicle is stuck in sand, mud, ice, snow,
or gravel. If the vehicle becomes stuck, seeIf
the Vehicle Is Stuck 0187.
Cruise Control
The cruise control lets the vehicle maintain a
speed of about 40 km/h (25 mph) or more
without keeping your foot on the
accelerator. Cruise control does not work at
speeds below 40 km/h (25 mph).
{Warning
Cruise control can be dangerous where
you cannot drive safely at a steady
speed. Do not use cruise control on
winding roads or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could lose
control. Do not use cruise control on
slippery roads.
With the Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control (ESC),
the system may begin to limit wheel spin
while you are using cruise control. If this
happens, the cruise control will
automatically disengage. See Traction
Control/Electronic Stability Control 0206.

6. Verify coolant level after the engine isshut off and the coolant is cold.
If necessary, repeat coolant fill procedure
Steps 1–6.
If the coolant still is not at the proper
level when the system cools down again,
see your dealer.
Caution
If the pressure cap is not tightly installed,
coolant loss and engine damage may
occur. Be sure the cap is properly and
tightly secured.
Automatic Coolant Service Fill Instruction
If equipped, this feature assists in filling and
removing air from the cooling system after
service of components or when coolant is
added after being too low.
To activate the fill and air removal process:
1. With a cold system, open the surge tank cap and add coolant to the indicated
mark on the surge tank.
2. Connect the vehicle to a battery charger.
3. Turn the ignition to Service Mode. See Ignition Positions (Key Access) 0191 or
Ignition Positions (Keyless Access) 0192.
4. Turn off the air conditioning. 5. Set the parking brake.
6. At the same time, press the accelerator
and the brake for two seconds, then
release.
At the end of the cycle, check the coolant
level in the surge tank and add coolant if it
is low. Turn off the vehicle, allow the Engine
Control Module (ECM) to go to sleep, about
two minutes, and repeat Steps 3-7.
Listen for pump activation and movement of
the control valves while watching the level
of the coolant in the surge tank. If the tank
empties, turn the ignition off, carefully
remove the surge tank cap, refill to the
indicated mark, and repeat Steps 4-7. The fill
and air removal process will run for
approximately 10 minutes.
Engine Overheating
The vehicle has an engine coolant
temperature gauge to warn of the engine
overheating. See Engine Coolant
Temperature Gauge 094.
If the decision is made not to lift the hood
when this warning appears, get service help
right away. See Roadside Assistance Program
0 335. If the decision is made to lift the hood,
make sure the vehicle is parked on a level
surface.
Then check to see if the engine cooling fan
is running. If the engine is overheating, the
fan should be running. If it is not, do not
continue to run the engine. Have the vehicle
serviced.
Caution
Do not run the engine if there is a leak
in the engine cooling system. This can
cause a loss of all coolant and can
damage the system and vehicle. Have
any leaks fixed right away.
If Steam Is Coming from the Engine
Compartment
{Warning
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system,
