Driving and Operating 169
To shift out of P (Park), the vehicle
must be in ON/RUN and the brake
pedal must be applied.
Stopping the Engine/OFF (No
Indicator Lights) :When the
vehicle is stopped, press ENGINE
START/STOP once to turn the
engine off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory
Power (RAP) 0173.
If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display a
message in the Driver Information
Center (DIC). See Transmission
Messages 0133. When the vehicle
is shifted into P (Park), the ignition
system will switch to OFF.
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 shut 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). Turn the ignition to
LOCK/OFF.
4. Set the parking brake. See Parking Brake 0181.
{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 shut 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
ENGINE START/STOP 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
run down.
ON/RUN/START (Green Indicator
Light) : This mode is for driving and
starting. With the ignition off, and
the brake pedal applied, pressing
ENGINE START/STOP once will
place the ignition system in ON/
RUN/START. Once engine cranking
begins, release the button. Engine
cranking will continue until the

170 Driving and Operating
engine starts. SeeStarting the
Engine 0170. The ignition will then
remain in ON/RUN.
Service Only 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 ENGINE
START/STOP for more than
five seconds will place the vehicle in
Service Only 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 Only
Mode. Press ENGINE START/STOP
again to turn the vehicle off.Starting the Engine
Place the transmission in the
proper gear.
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.
See Add-On Electrical Equipment
0 209.
Move the shift lever to P (Park) or
N (Neutral). To restart the vehicle
when it 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. 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
your engine gets warm. Do not
race the engine immediately
after starting it.
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

178 Driving and Operating
Warning (Continued)
You could lose control and hit
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Caution
Shifting out of P (Park) or
N (Neutral) with the engine
running at high speed may
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle.
D : This position is for normal
driving. It provides the best fuel
economy. If more power is needed
for passing, and the vehicle is:
. Going less than 56 km/h
(35 mph), push the accelerator
pedal about halfway down. .
Going about 56 km/h (35 mph) or
more, push the accelerator all
the way down.
Caution
If the vehicle does not shift gears,
the transmission could be
damaged. Have the vehicle
serviced right away.
Operating Modes
The transmission may operate in a
lower gear than normal to improve
vehicle performance. The engine
speed may be higher and there may
be an increase in noise during the
following conditions:
. When climbing a grade.
. When driving downhill.
. When driving in hot
temperatures or at high altitude.
Manual Mode
Driver Shift Control (DSC)
Caution
Driving with the engine at a high
rpm without upshifting while using
Driver Shift Control (DSC), could
damage the vehicle. Always
upshift when necessary while
using DSC.

9804381) - 2017 - crc - 8/30/16
Driving and Operating 179
DSC allows you to shift an
automatic transmission similar to a
manual transmission. To use the
DSC feature:1. Move the shift lever to the left from D (Drive) into the side
gate marked with (+) and (−).
2. Press the shift lever forward to upshift or rearward to
downshift.
While using the DSC feature, the
vehicle will have firmer, quicker
shifting. You can use this for sport
driving or when climbing or
descending hills, to stay in gear
longer, or to downshift for more
power or engine braking.
The transmission will only allow you
to shift into gears appropriate for the
vehicle speed and engine
revolutions per minute (rpm). The
transmission will not automatically
shift to the next lower gear if the
engine rpm is too high, nor to the
next higher gear when the maximum
engine rpm is reached. While in the DSC mode, the
transmission will automatically
downshift when the vehicle comes
to a stop. This will allow for more
power during take-off.
When accelerating the vehicle from
a stop in snowy and icy conditions,
you may want to shift into second
gear. A higher gear allows the
vehicle to gain more traction on
slippery surfaces. Vehicles with a
turbocharged engine may also start
in third gear.Drive Systems
All-Wheel Drive
If equipped, this feature transfers
torque to the rear wheels as
required. It is fully automatic, and
adjusts itself as needed for road
conditions.
All-Wheel Drive (AWD) performance
is automatically reduced when you
use the compact spare. To restore
full AWD performance, and prevent
excessive wear to the clutch in the
AWD system, replace the compact
spare tire with a full-size tire as
soon as possible. See
Compact
Spare Tire 0277.
