270 Driving and Operating
If the remote key is not in
the vehicle, if there is
interference, or if the
remote key battery is low,
a Driver Information
Center (DIC) message will
display. See Remote Key
Operation09.
Caution
Cranking the engine for long
periods of time, by pressing
ENGINE START/STOP
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 hold it there, then press ENGINE
START/STOP 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 button
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.
Stopping the Engine
If the vehicle has an automatic
transmission, move the shift
lever to P (Park) and press and
hold ENGINE START/STOP on
the instrument panel, until the
engine shuts off. If the shift
lever is not in P (Park), the
engine shuts off and the
ignition goes to accessory
mode. The DIC displays SHIFT
TO PARK. Once the shift lever
is moved to P (Park), the
vehicle turns off.
If the vehicle has a manual
transmission, before getting
out of the vehicle, shift to
1 (First) or R (Reverse) and
apply the parking brake. Then
turn off the ignition off by
pressing ENGINE START/
STOP and release the clutch
pedal when the engine has
stopped.
If the remote key is not
detected inside the vehicle
when it is turned off the DIC
displays a message.
Stop/Start System
If equipped, the Stop/Start
system will shut off the engine
to help conserve fuel. It has
components designed for the
increased number of starts.

290 Driving and Operating
Warning (Continued)
use proper care when
driving may result in injury,
death, or vehicle damage.
See Defensive Driving0242.
When the vehicle is stopped
on a grade, Hill Start Assist
(HSA) temporarily prevents
the vehicle from rolling in an
unintended direction during
the transition from brake
pedal release to accelerator
pedal apply. The brakes
release when the accelerator
pedal is applied or
automatically release after a
few seconds. The brakes may
also release under other
conditions. Do not rely on HSA
to hold the vehicle.
HSA is available when the
vehicle is facing uphill in a
forward gear, or when facing
downhill in R (Reverse). The
vehicle must come to a
complete stop on a grade for
HSA to activate.
Automatic Vehicle
Hold (AVH)
{Warning
Do not rely on this feature.
It does not replace the need
to pay attention and drive
safely. You may not hear or
feel alerts or warnings
provided by this system.
Failure to use proper care
when driving may result in
injury, death, or vehicle
damage. When Automatic Vehicle Hold
(AVH) is turned on and the
vehicle is braked to a stop,
AVH prevents the vehicle from
moving during the transition
from brake pedal release to
accelerator pedal apply. The
brakes release when the
accelerator pedal is applied.
The brakes may also release
under other conditions. Do not
rely on AVH to hold the
vehicle.
If the accelerator pedal is not
applied within a few minutes,
the Electric Parking Brake will
apply. The parking brake will
also apply if the driver door is
opened or the driver seat belt
is unfastened while AVH is
holding the vehicle.
AVH can be turned on by
pressing AUTO HOLD. The
indicator light on the switch
will come on. The AVH light on
the instrument panel will come
on while AVH is actively

If equipped, the following
driver assistance features
should be turned to alert or
off when towing a trailer:
.Automatic Emergency
Braking (AEB)
.Intelligent Brake Assist (IBA)
.Front Pedestrian
Braking (FPB)
If equipped with Lane Change
Alert (LCA), the LCA detection
zones that extend back from
the side of the vehicle do not
move further back when a
trailer is towed. Use caution
while changing lanes when
towing a trailer.
If equipped with Rear Cross
Traffic Alert (RCTA), use
caution while backing up when
towing a trailer, as the RCTA
detection zones that extend out from the back of the
vehicle do not move further
back when a trailer is towed.
{Warning
To prevent serious injury or
death from carbon monoxide
(CO), when towing a trailer:
.Do not drive with the
liftgate, trunk/hatch,
or rear-most
window open.
.Fully open the air outlets
on or under the
instrument panel.
.Adjust the climate control
system to a setting that
brings in only outside air.
See
“Climate Control
Systems” in the Index.
For more information about
carbon monoxide, see
Engine Exhaust 0276.
Towing a trailer requires
experience. The combination
of the vehicle and trailer is
longer and not as responsive as the vehicle itself. Become
familiar with handling and
braking by driving on a level
road surface before driving on
public roads.
The trailer structure, the tires,
and the brakes must be all be
rated to carry the intended
cargo. Inadequate trailer
equipment can cause the
combination to operate in an
unexpected or unsafe manner.
Before driving, inspect all
trailer hitch parts and
attachments, safety chains,
electrical connectors, lamps,
tires, and mirrors. See Towing
Equipment
0371. If the trailer
has electric brakes, start the
combination moving and then
manually apply the trailer
brake controller to check the
trailer brakes work. During the
trip, occasionally check that
the cargo and trailer are
secure and that the lamps and
any trailer brakes are working.
