test, or replace the high voltage
battery. See your dealer if the high
voltage battery needs service. The
dealer has information on how to
recycle the high voltage battery.
The hybrid high voltage battery is
cooled with air drawn from the
vehicle interior. The cold air intake
for the battery is under the rear
seat. Do not block the area in front
of the cold air intake.
{Warning
Damage to the high voltage
battery or high voltage system
can create a risk of electric shock,
overheating, or fire.
If the vehicle is damaged from a
moderate to severe crash, flood,
fire, or other event, the vehicle
should be inspected as soon as
possible. Until the vehicle has
been inspected, store it outside at
least 15 m (50 ft) from any(Continued)

structure or anything that can
burn. Ventilate the vehicle by
opening a window or a door.
Contact Customer Assistance as
soon as possible to determine
whether an inspection is needed.

0 377.
Stop/Start System
If equipped with the 1.5L L4 engine,
the vehicle has a Stop/Start system
to shut off the engine to help
conserve fuel. See Starting the
Engine 0218.
Vehicles with a 1.5L engine have an
Absorbed Glass Mat (AGM) 12-volt
battery. Installation of a standard
12-volt battery will result in reduced
12-volt battery life.
When using a 12-volt battery
charger on the 12-volt AGM battery,
some chargers have an AGM
battery setting on the charger. If available, use the AGM setting on
the charger, to limit charge voltage
to 14.8 volts.
{Warning
WARNING:
Battery posts,
terminals, and related
accessories contain lead and lead
compounds, chemicals known to

cancer and birth defects or other
reproductive harm. Batteries also
contain other chemicals known to
the State of California to cause
cancer. WASH HANDS AFTER

high-quality tires made by a
leading tire manufacturer. See
the warranty manual for
information regarding the tire
warranty and where to get
service. For additional
information refer to the tire
manufacturer.
{Warning
.Poorly maintained and
improperly used tires are
dangerous.
.Overloading the tires can
cause overheating as a
result of too much
flexing. There could be a
blowout and a serious
crash. See Vehicle Load
Limits 0212.

Treadwear Indicators:Narrow
bands, sometimes called wear
bars, that show across the tread
of a tire when only 1.6 mm
(1/16 in) of tread remains. See
When It Is Time for New Tires
0 323.
UTQGS (Uniform Tire Quality
Grading Standards)
:A tire
information system that provides
consumers with ratings for a
tire's traction, temperature, and
treadwear. Ratings are
determined by tire
manufacturers using
government testing procedures.
The ratings are molded into the
sidewall of the tire. See Uniform
Tire Quality Grading 0326.
Vehicle Capacity Weight
:The
number of designated seating
positions multiplied by
68 kg (150 lb) plus the rated
cargo load. See Vehicle Load
Limits 0212. Vehicle Maximum Load on the
Tire
:Load on an individual tire
due to curb weight, accessory
weight, occupant weight, and
cargo weight.
Vehicle Placard
:A label
permanently attached to a
vehicle showing the vehicle
capacity weight and the original
equipment tire size and
recommended inflation pressure.
See “Tire and Loading
Information Label” underVehicle
Load Limits 0212.
Tire Pressure
Tires need the correct amount of
air pressure to operate
effectively. Caution
Neither tire underinflation nor
overinflation is good.
Underinflated tires, or tires
that do not have enough air,
can result in:
.Tire overloading and
overheating which could
lead to a blowout.
.Premature or
irregular wear.
.Poor handling.
.Reduced fuel economy.
Overinflated tires, or tires that
have too much air, can
result in:
.Unusual wear.
.Poor handling.
.Rough ride.
.Needless damage from
road hazards.
