Tire Pressure Monitor
This vehicle may have a Tire Pressure
Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in pressure
of one of the vehicle's tires. If the
warning light comes on, stop as soon
as possible and inflate the tires to the
recommended pressure shown on the
Tire and Loading Information label.
See Vehicle Load Limits 0213. The
warning light will remain on until the
tire pressure is corrected. The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the tire
pressures are getting low and the tires
need to be inflated to the proper
pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.

Fuel (2.0L L4 Turbo Engine)
Premium Recommended Fuel
Use premium 93 octane unleaded
gasoline in your vehicle. Unleaded
gasoline with an octane rating as low
as 87 may be used, but it will reduce
performance and fuel economy. See
Fuel 0286.

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.

SEATS AND RESTRAINTS 89
Both roof-rail airbags will inflate when
either side of the vehicle is struck,
if the sensing system predicts that the
vehicle is about to roll over on its
side, or in a severe frontal impact.
In any particular crash, no one can
say whether an airbag should have
inflated simply because of the vehicle
damage or repair costs.
What Makes an Airbag
Inflate?
In a deployment event, the sensing
system sends an electrical signal
triggering a release of gas from the
inflator. Gas from the inflator fills the
airbag causing the bag to break out of
the cover. The inflator, the airbag, and
related hardware are all part of the
airbag module.
For airbag locations, seeWhere Are the
Airbags? 086.
How Does an Airbag
Restrain?
In moderate to severe frontal or near
frontal collisions, even belted
occupants can contact the steering wheel or the instrument panel. In
moderate to severe side collisions,
even belted occupants can contact the
inside of the vehicle.
Airbags supplement the protection
provided by seat belts by distributing
the force of the impact more evenly
over the occupant's body.
Rollover capable roof-rail airbags are
designed to help contain the head and
chest of occupants in the outboard
seating positions in the first and
second rows. The rollover capable
roof-rail airbags are designed to help
reduce the risk of full or partial
ejection in rollover events, although
no system can prevent all such
ejections.
But airbags would not help in many
types of collisions, primarily because
the occupant's motion is not toward
those airbags. See
When Should an
Airbag Inflate? 088.
Airbags should never be regarded as
anything more than a supplement to
seat belts.
What Will You See after an
Airbag Inflates?
After frontal, knee, and seat-mounted
side impact airbags inflate, they
quickly deflate, so quickly that some
people may not even realize the
airbags inflated. Roof-rail airbags may
still be at least partially inflated for
some time after they inflate. Some
components of the airbag module may
be hot for several minutes. For
location of the airbags, see Where Are
the Airbags? 086.
The parts of the airbag that come into
contact with you may be warm, but
not too hot to touch. There may be
some smoke and dust coming from
the vents in the deflated airbags.
Airbag inflation does not prevent the
driver from seeing out of the
windshield or being able to steer the
vehicle, nor does it prevent people
from leaving the vehicle.

INSTRUMENTS AND CONTROLS 143
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio and
air conditioner.
Charge Cord Connected
(PLUG-IN Only)
This light comes on when a charge
cord is connected to the vehicle.
Malfunction Indicator Lamp
(Check Engine Light)
This light is part of the vehicle’s
emission control on-board diagnostic
system. If this light is on while the
engine is running, a malfunction has
been detected and the vehicle may
require service. The light should come
on to show that it is working when
the ignition is in Service Mode. See
Ignition Positions0217.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when it
comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not run
smoothly. This could lead to costly
repairs that might not be covered
by the vehicle warranty.
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not meet
the original tire specifications, can
cause this light to come on. This
could lead to costly repairs not
covered by the vehicle warranty.
This could also affect the vehicle’s
ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications 0298.
If the light is f lashing : A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service may
be required.
To help prevent damage, reduce
vehicle speed and avoid hard
accelerations and uphill grades.
If towing a trailer, reduce the amount
of cargo being hauled as soon as
possible.

144 INSTRUMENTS AND CONTROLS
If the light continues to flash, find a
safe place to park. Turn the vehicle off
and wait at least 10 seconds before
restarting the engine. If the light is
still flashing, follow the previous
guidelines and see your dealer for
service as soon as possible.
If the light is on steady :A
malfunction has been detected.
Diagnosis and service may be
required.
Check the following:
. If fuel has been added to the
vehicle using the capless fuel
funnel adapter, make sure that it
has been removed. See “Filling the
Tank with a Portable Gas Can ”
under Filling the Tank 0288. The
diagnostic system can detect if the
adapter has been left installed in
the vehicle, allowing fuel to
evaporate into the atmosphere.
A few driving trips with the
adapter removed may turn off the
light.
. Poor fuel quality can cause
inefficient engine operation and
poor driveability, which may go
away once the engine is warmed up. If this occurs, change the fuel
brand. It may require at least one
full tank of the proper fuel to turn
the light off. See
Fuel0286.
If the light remains on, see your
dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering wheel.
Connecting devices that are not used
to perform an Emissions Inspection/
Maintenance test or to service the
vehicle may affect vehicle operation.
See Add-On Electrical Equipment 0295.
See your dealer if assistance is needed. The vehicle may not pass
inspection if:
.
The light is on when the engine is
running.
. The light does not come on when
the ignition is in Service Mode.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if the
12-volt battery has recently been
replaced or run down, or if the
vehicle has been recently serviced.
See your dealer if the vehicle will not
pass or cannot be made ready for
the test.
