Forward Collision Alert
(FCA) System
If equipped, FCA may help avoid or
reduce the harm caused by front-end
crashes. FCA provides a green
indicator,
V, when a vehicle is
detected ahead. This indicator
displays amber if you follow a vehicle
much too closely. When approaching a
vehicle ahead too quickly, FCA
provides a flashing red alert on the
windshield and rapidly beeps or pulses
the driver seat.
See Forward Collision Alert (FCA)
System 0260.
Night Vision System
If equipped, this system can help the
driver see and alert the driver to
pedestrians or large animals ahead of
the vehicle beyond the area lit by the
headlamps.
See Night Vision System 0266.
Forward Automatic
Braking (FAB)
If the vehicle has Forward Collision
Alert (FCA), it also has FAB, which
includes Intelligent Brake Assist (IBA).
When the system detects a vehicle
ahead in your path that is traveling in
the same direction that you may be
about to crash into, it can provide a
boost to braking or automatically
brake the vehicle. This can help avoid
or lessen the severity of crashes when
driving in a forward gear.
See Forward Automatic Braking (FAB)
0 262.
Front Pedestrian Braking
(FPB) System
If equipped, the FPB system may
help avoid or reduce the harm caused
by front-end crashes with nearby
pedestrians when driving in a
forward gear. FPB displays an amber
indicator,
~, when a nearby
pedestrian is detected directly ahead.
When approaching a detected
pedestrian too quickly, FPB provides a
red flashing alert on the windshield

Driving for Better Fuel
Economy (Gasoline Only)
Driving habits can affect fuel mileage.
Here are some driving tips to get the
best fuel economy possible.
.
Avoid fast starts and accelerate
smoothly.
. Brake gradually and avoid abrupt
stops.
. Avoid idling the engine for long
periods of time.
. When road and weather
conditions are appropriate, use
cruise control.
. Always follow posted speed limits
or drive more slowly when
conditions require.
. Keep vehicle tires properly
inflated.
. Combine several trips into a
single trip. .
Replace the vehicle's tires with the
same TPC Spec number molded
into the tire's sidewall near
the size.
. Follow recommended scheduled
maintenance.Driving for Better Energy
Efficiency (PLUG-IN Only)
Use the following tips to help
maximize energy efficiency and range.
In colder temperatures, while these
efficiency tips will help, the electric
vehicle driving range may be lower
due to higher energy usage.
Driving Style
Acceleration/Braking/Coasting
Avoid unnecessary rapid accelerations
and decelerations.
Electric range is maximized at
80 km/h (50 mph) and below. Higher
speeds use more energy and can
significantly reduce electric range.
Use cruise control when appropriate. Plan ahead for decelerations and coast
whenever possible. For example, do
not rush to traffic signals.
Do not shift to N (Neutral) to coast.
The vehicle recovers energy while
coasting and braking in D (Drive) or M
(Manual Mode).
Drive Mode and PRNDM Selection
Use Tour Mode when possible.
Sport Mode provides more responsive
acceleration than Tour Mode but can
reduce efficiency.
Use Hold Mode on a trip where it is
expected that all of the electric charge
will be depleted. Use Hold Mode
mainly during highway or high speed
driving to maximize both EV miles
and fuel efficiency.
Use M (Manual Model) in heavy
stop-and-go traffic or when traveling
downhill. M (Manual Mode) requires
less brake pedal application and
provides a controlled, efficient way to
slow the vehicle down.
