Door Locks
{Warning
Unlocked doors can be
dangerous.
. Passengers, especially
children, can easily open
the doors and fall out of a
moving vehicle. The doors
can be unlocked and
(Continued)
Warning (Continued)
opened while the vehicle is
moving. The chance of
being thrown out of the
vehicle in a crash is
increased if the doors are
not locked. So, all
passengers should wear
seat belts properly and the
doors should be locked
whenever the vehicle is
driven.
. Young children who get into
unlocked vehicles may be
unable to get out. A child
can be overcome by
extreme heat and can suffer
permanent injuries or even
death from heat stroke.
Always lock the vehicle
whenever leaving it.
. Outsiders can easily enter
through an unlocked door
when you slow down or stop
the vehicle. Locking the
doors can help prevent this
from happening.

attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0243.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.

Vehicle Care 247
{Warning
An underhood electric fan can
start up even when the engine is
not running and can cause injury.
Keep hands, clothing, and tools
away from any underhood
electric fan.
If the coolant inside the coolant
surge tank is boiling, do not do
anything else until it cools down.
The vehicle should be parked on a
level surface.
The coolant level should be up to
the cold fill line. If it is not, there
might be a leak at the radiator
hoses, heater hoses, radiator, water
pump, or somewhere else in the
cooling system.
{Warning
Do not touch heater or radiator
hoses, or other engine parts.
They can be very hot and can (Continued)
Warning (Continued)
burn you. Do not run the engine if
there is a leak; all coolant could
leak out. That could cause an
engine fire and can burn you. Fix
any leak before driving the
vehicle.
If there seems to be no leak, with
the engine on, check to see if the
cooling fans are running. If the
engine is overheating, the fans
should be running. If they are not,
the vehicle needs service. Turn off
the vehicle.
Engine Coolant
The engine cooling system in the
vehicle is filled with GM Premix
DEX-COOL engine coolant. See
Recommended Fluids and
Lubricants 0329. The coolant
requires changing at certain
intervals. See Maintenance
Schedule 0321. The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
see
Engine Overheating 0252.
What to Use
{Warning
Plain water, or other liquids such
as alcohol, can boil before the
proper coolant mixture will. With
plain water or the wrong mixture,
the engine could get too hot but
there would not be an overheat
warning. The engine could catch
fire and you or others could be
burned.
Use GM Premix DEX-COOL engine
coolant. This mixture:
. Gives freezing protection down
to−37 °C (−34 °F), outside
temperature.
. Gives boiling protection up to
129 °C (265 °F), engine
temperature.

.Protects against rust and
corrosion.
. Will not damage aluminum parts.
. Helps keep the proper engine
temperature.
Caution
Do not use anything other than a
pre-mix of DEX-COOL coolant
that meets GM Standard
GMW3420 and deionized water.
Anything else can cause damage
to the hybrid cooling system
components and the vehicle,
which would not be covered by
the vehicle warranty.
Never dispose of engine coolant by
putting it in the trash, pouring it on
the ground, or into sewers, streams,
or bodies of water. Have the coolant
changed by an authorized service
center, familiar with legal
requirements regarding used
coolant disposal. This will help
protect the environment and your
health.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible in
the coolant surge tank. If the coolant
inside the coolant surge tank is
boiling, do not do anything else until
it cools down. If coolant is visible
but the coolant level is not at or
above the cold fill line, add GM
Premix DEX-COOL engine coolant.
Be sure the cooling system is cool
before this is done. See Engine
Overheating 0252.
The coolant surge tank is on the
driver side of the engine
compartment. See Engine
Compartment Overview 0240.
The coolant level should be at or
above the cold fill line on the
coolant surge tank. If it is not, there
could be a leak in the cooling
system.
How to Add Coolant to the
Coolant Surge Tank
{Warning
Spilling coolant on hot engine
parts can burn you. Coolant
contains ethylene glycol and it will
burn if the engine parts are hot
enough.

Caution
If the pressure cap is not tightly
installed, coolant loss and engine
damage may occur. Be sure the
cap is properly and tightly
secured.
Cooling System (High
Voltage Battery)
During vehicle operation and also
during charging, the high voltage
battery cells in the vehicle are kept
within a normal operating
temperature range. If the high
voltage battery cell temperature
rises above the normal operating
temperature range, the battery
cooling system turns on the air
conditioning compressor and cools
the coolant until the correct battery
cell temperature is reached. If the
high voltage battery cell temperature
falls below the normal operating
temperature range, a high voltage
heater, located in the battery, heats
the coolant until the correct battery
cell temperature is reached.During high voltage battery system
cooling, you may feel temperature
changes at the air vents due to the
extra load on the system.
What to Use
The high voltage battery coolant
reservoir in the vehicle is filled with
GM Premix DEX-COOL engine
coolant. See
Recommended Fluids
and Lubricants 0329. If using this
mixture, nothing else needs to be
added.
The coolant needs to be replaced at
the appropriate interval. See
Maintenance Schedule 0321.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The high voltage battery coolant
reservoir is located in the engine
compartment. See Engine
Compartment Overview 0240.
1. High Voltage Battery
Coolant Reservoir
2. Power Electronics Coolant Reservoir
Check to see if coolant is visible in
the high voltage battery coolant
reservoir (1). If coolant is visible but
the coolant level is below the cold
fill line on the side of the reservoir,
there could be a leak in the cooling
system.
The high voltage battery cooling
system supports the operation of
sensitive electronics that are critical
to vehicle operation.

Vehicle Care 251
The high voltage battery cooling
system should only be serviced by a
qualified technician.
Cooling System (Power
Electronics and Charger
Modules)
The power electronics and charger
modules are cooled using the same
coolant loop.
The power electronics and charger
modules in the vehicle are kept
below a maximum temperature
threshold. If the coolant temperature
rises above this temperature
threshold, the electric cooling fans
will turn on and cool the coolant
until the correct temperature is
reached.
What to Use
The power electronics and charger
modules coolant reservoir in the
vehicle is filled with GM Premix
DEX-COOL engine coolant. See
Recommended Fluids and
Lubricants0329. If using this
mixture, nothing else needs to be
added.
The coolant needs to be replaced at
the appropriate interval. See
Maintenance Schedule 0321.

there could be a leak in the cooling
system.
The power electronics cooling
