If the CHANGE ENGINE OIL
SOON message is not on, the
system is reset.
See Engine Oil Life System 0309.
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.

INSTRUMENTS AND CONTROLS 165
Oil Life :Shows an estimate of the
oil's remaining useful life.
If REMAINING OIL LIFE 99% is
displayed, that means 99% of the
current oil life remains.
When the remaining oil life is low, the
CHANGE ENGINE OIL SOON message
will appear on the display. The oil
should be changed as soon as
possible. See Engine Oil0307. In
addition to the engine oil life system
monitoring the oil life, additional
maintenance is recommended. See
Maintenance Schedule 0390.
The Oil Life display must be reset
after each oil change. It will not reset
itself. Do not reset the Oil Life display
accidentally at any time other than
when the oil has just been changed.
It cannot be reset accurately until the
next oil change. To reset the engine
oil life system, press and hold SEL for
several seconds while the Oil Life
display is active. See Engine Oil Life
System 0309.
Tire Pressure : Shows the
approximate pressures of all four tires.
Tire pressure is displayed in either
kilopascal (kPa) or in pounds per square inch (psi). If the pressure is
low, the value for that tire is shown in
amber.
See
Tire Pressure Monitor System 0349
and Tire Pressure Monitor Operation
0 350.
Vehicle Odometer (Base Cluster) :
Shows the odometer.
Blank Page : Allows for no
information to be displayed in the
cluster info display areas.
Head-Up Display (HUD)
{Warning
If the HUD image is too bright or
too high in your field of view, it
may take you more time to see
things you need to see when it is
dark outside. Be sure to keep the
HUD image dim and placed low in
your field of view.
If equipped with HUD, some
information concerning the operation
of the vehicle is projected onto the
windshield. The image is projected
through the HUD lens on top of the instrument panel. The information
appears as an image focused out
toward the front of the vehicle.
Caution
If you try to use the HUD image as
a parking aid, you may misjudge
the distance and damage your
vehicle. Do not use the HUD image
as a parking aid.
The HUD information can be
displayed in various languages in
some vehicles. The speedometer
reading and other numerical values
can be displayed in either English or
metric units.
The language selection is changed
through the radio and the units of
measurement is changed through the
instrument cluster. See Vehicle
Personalization 0170 and “Cluster
Options Menu ”under Instrument
Cluster (Base Level) 0127 or
Instrument Cluster (Uplevel) 0130.
