Starting and Stopping the Engine –
Frequently Asked Questions
Why is the engine idle speed high when I
am starting the engine?
The speed at which the engine idles
immediately after starting is optimized
to minimize vehicle emissions and
maximize cabin comfort and fuel
economy.
Why does the engine not crank? You can only attempt to start the engine
for a limited amount of time before the
starting system temporarily disables. If
you exceed the starting time limit, a
message may appear and you cannot
attempt to start the engine for at least
15 minutes. Why do I experience different driving
characteristics?
If you disconnect the battery, your
vehicle may exhibit some unusual
driving characteristics for approximately
5 mi (8 km) after you reconnect it. This
is because the engine management
system must realign itself with the
engine. You can disregard any unusual
driving characteristics during this period.
Why can I not start the engine? If you cannot start the engine after 3
attempts, wait 10 seconds and do the
following:
1. Fully press the brake pedal.
Note: Make sure that the parking brake is
applied.
Note: Make sure that the transmission is in
park (P) or neutral (N).
2. Fully press the accelerator pedal and hold it there.
3. Press the push button ignition switch.
Note: The engine cranks for a short period
of time and then it stops. 4. Release the accelerator pedal.
5. Press the push button ignition switch.
Why does the system not detect a passive
key?
If the system does not detect a passive
key and you are unable to start the
engine, insert the passive key into the
backup position and press the push
button ignition switch to start the
engine. See Accessing the Passive Key
Backup Position
(page 190).

WHAT IS AUTO-START-STOP
The system is designed to help reduce fuel
consumption and CO
2 emissions by stopping
the engine when it is idling, for example at
traffic lights.
AUTO-START-STOP PRECAUTIONS WARNING: Apply the parking brake,
shift into park (P), switch the ignition off
and remove the key before you leave your
vehicle. Failure to follow this instruction
could result in personal injury or death. WARNING: Apply the parking brake,
shift into park (P), switch the ignition off
and remove the key before you open the
hood or have any service or repair work
completed. If you do not switch the ignition
off, the engine could restart at any time.
Failure to follow this instruction could result
in personal injury or death. SWITCHING AUTO-START-STOP
ON AND OFF
Press the driver assistance button on the
instrument panel to access the
Auto-Start-Stop feature on the touchscreen.
Use the touchscreen to deactivate the
feature. Deactivating the feature lasts only
one key cycle. Use the touchscreen to
restore Auto-Start-Stop function.STOPPING THE ENGINE
Stop your vehicle, keep your foot on the
brake pedal and the transmission in drive
(D).
Note:
Power assist steering turns off when
the engine stops.
RESTARTING THE ENGINE
Release the brake pedal or press the
accelerator pedal.
A message appears in the information
display if the system requires you to take
action.
AUTO-START-STOP INDICATORS WARNING: The system may require
the engine to automatically restart when
the auto-start-stop indicator illuminates
green or flashes amber. Failure to follow
this instruction could result in personal
injury.

Note:
You can start your vehicle in this
position.
Drive (D)
Drive (D) is the normal driving position, and
allows automatic upshifts and downshifts
through all available gears.
Sport (S)
Putting the vehicle in sport (S):
• Provides additional engine braking and
extends lower gear operation to enhance
performance for uphill climbs, hilly terrain
or mountainous areas. This increases
engine RPM during engine braking.
• Provides additional lower gear operation
through the automatic transmission shift
strategy.
• Provides gear selection more quickly and
at higher engine speeds.
Note: You can shift into sport at any vehicle
speed. SHIFTING YOUR VEHICLE INTO
GEAR
The gear selector is located near the middle
of the instrument panel. Press a button to
select a gear.
•
Park (P)
• Reverse (R)
• Neutral (N)
• Drive (D)
• Sport (S) (If equipped)
Note: The gear selector prevents shifting out
of park (P) when the intelligent access key
is outside the vehicle. Note:
The gear selector will automatically
return to park (P) when you take actions
associated with leaving the vehicle. See
How Does Automatic Return to Park (P)
Work
(page 209).

PARKING AID PRECAUTIONS
WARNING: To help avoid personal
injury, always use caution when in reverse
(R) and when using the sensing system. WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care and
attention. Failure to take care may result
in a crash. WARNING:
Traffic control systems,
fluorescent lamps, inclement weather, air
brakes, external motors and fans may
affect the correct operation of the sensing
system. This may cause reduced
performance or false alerts. WARNING:
The system may not
detect small or moving objects, particularly
those close to the ground. WARNING:
The parking aid system
can only assist you to detect objects when
your vehicle is moving at parking speeds.
To help avoid personal injury you must
take care when using the parking aid
system. WARNING:
The system may not
function if the sensor is blocked. WARNING:
In cold and severe
weather conditions the system may not
function. Rain, snow and spray can all limit
sensor performance. WARNING:
If damage occurs in the
immediate area surrounding the sensor,
have your vehicle checked as soon as
possible.
Note: If your vehicle sustains damage
leaving the sensors misaligned, this will
cause inaccurate measurements or false
alerts. When you connect a trailer to your vehicle,
the rear parking aid detects the trailer and
provides an alert. Disable the parking aid
when you connect a trailer to prevent the
alert.
Note:
Certain add-on devices installed
around the bumper or fascia may create
false alerts, for example, large trailer hitches,
bike or surfboard racks, license plate
brackets, bumper covers or any other device
that could block the normal detection zone
of the parking aid system. Aftermarket spare
tires or spare tire covers mounted to the rear
tailgate could cause false alerts from the
park aid system. Remove the add-on device
to prevent false alerts.
Note: Keep the sensors free from snow, ice
and large accumulations of dirt. If the
sensors are covered, the system's accuracy
can be affected.
Do not clean the sensors with sharp objects.
Note: When using a programmed MyKey
you cannot switch this off.
See MyKey™
(page 84).

SWITCHING PARKING AID ON AND
OFF
Press the parking aid button and
use the menu to turn the system
on and off.
The system can also be turned off using the
pop-up message that appears when you are
in reverse (R).
REAR PARKING AID
What is the Rear Parking Aid
Rear parking sensors detect objects behind
your vehicle when in reverse (R).
Rear Parking Aid Limitations
There is a decreased coverage area at the
outer corners.
When using a programmed MyKey, you
cannot switch the rear parking aid off. The rear parking aid sensors are active when
your vehicle is in reverse (R) and the vehicle
speed is less than 3 mph (5 km/h).
The sensor coverage area is up to
71 in
(180 cm) from the rear bumper.
The rear parking aid detects large objects
when you shift into reverse (R) and any of
the following occur:
• Your vehicle is moving backward at a low
speed.
• Your vehicle is stationary but an object
is approaching the rear of your vehicle
at a low speed.
• Your vehicle is moving backward at a low
speed and an object is moving towards
your vehicle, for example another vehicle
at a low speed. Locating the Rear Parking Aid Sensors
The rear parking aid sensors are in the rear
bumper.
Rear Parking Aid Audible Warnings
A warning tone sounds when your vehicle
approaches an object. As your vehicle
moves closer to an object, the rate of the
tone increases. The warning tone
continuously sounds when an object is 12 in
(30 cm)
or less from the rear bumper.

Lane Centering Automatic Cancellation
When an external condition cancels the
system, for example, no lane markings
available, a tone sounds and a message
appears in the information display.
If your vehicle starts to slow down,
you must provide steering input to
the wheel and press and release
the button to regain full system performance.
Automatic cancellation can also occur if:
• The lane becomes too wide or too
narrow.
• The system cannot detect valid lane
markings.
• Lane markings cross over one another. Note:
The system disables until the next key
cycle if your vehicle slows down due to driver
inactivity twice within a key cycle.
Lane Centering Indicators Illuminates when you switch lane
centering on. The color of the
indicator changes to indicate the
system status.
Gray indicates the system is on but inactive.
Green indicates the system is active and
