automatically. You may not
be able to release the EPB
using the EPB switch.
It should automatically
release when the vehicle is
shifted out of P (Park).
Leaving the Vehicle with
the Engine Running
{Warning
It can be dangerous to leave
the vehicle with the engine
running. It could overheat
and catch fire.
It is dangerous to get out of
the vehicle if the vehicle is
not in P (Park) with the
Electric Parking Brake (EPB)
set. The vehicle can roll.
Do not leave the vehicle
when the engine is running.
If you have left the engine
running, the vehicle can
move suddenly. You or
others could be injured. To
be sure the vehicle will not
move, even when you are on
fairly level ground, always
set the EPB and shift the
vehicle to P (Park). If you are
towing a trailer, see Driving

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.
See Shifting Into Park0263
and Engine Exhaust 0265.
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.

carbon monoxide (CO),
which cannot be seen or
smelled. Exposure to CO can
cause unconsciousness and
even death.

such as a bicyclist.
.If the pedestrian is
wearing certain types of
clothing.
.If headlamps are off,
except when parked.
.If the outside temperature
is higher than 30 °C
(86 °F).
.Due to poor visibility,
including in heavy fog, rain,
or snow.
.If the sensor is blocked by
dirt, snow, rain, or ice.
Be ready to take action and
apply the brakes. For more
information, see Defensive
Driving 0240. Keep the
Night Vision sensor clean
and in good repair. Pedestrian detection may not
be available in high outside
temperatures. An amber icon,
*, displays. The system does
not need service.
In rain, snow, or fog the image
may not be clear and the
direction of the road ahead
may not be seen. In more
severe weather conditions,
the image may be unclear and
unusable. The system does
not need service.
Keep the system sensor clean
by activating the rear window
washer when it is dark enough
for the system to operate.
If the Night Vision image still
looks blurry, use a soft wet
cloth to gently clean the
sensor camera lens and dry
thoroughly. The sensor is
behind the lower front grille
below the driver side
headlamp.
The camera must also be
aligned to work correctly.

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.

Engine Overheating
The vehicle has several
indicators to warn of the
engine overheating.
There is an engine coolant
temperature gauge on the
instrument cluster. See Engine
Coolant Temperature Gauge
0131. The vehicle may also
display a message on the
Driver Information
Center (DIC).
If the decision is made not to
lift the hood when this
warning appears, get service
help right away. See Roadside
Assistance Program 0470.
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, including the
pressure cap, is hot. Wait for
the cooling system and
pressure cap to cool.
If No Steam Is Coming
from the Engine
Compartment
If an engine overheat warning
is displayed but no steam can
be seen or heard, the problem
may not be too serious.
Sometimes the engine can get
a little too hot when the
vehicle:
.Climbs a long hill on a
hot day.
.Stops after high-speed
driving.
.Idles for long periods in
traffic.
If the overheat warning is
displayed with no sign of
steam: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and
to the highest fan speed.
Open the windows as
necessary.
