Door Locks
{WARNING
Unlocked doors can be
dangerous.
.Passengers, especially
children, can easily open the
doors and fall out of a moving
vehicle. 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
safety belts properly and
the doors should be locked
whenever the vehicle is
driven. (Continued)
WARNING (Continued)
.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 slowing or stopping
the vehicle. Lock the doors
to help prevent this from
happening.
To lock or unlock the door, use
the Remote Keyless Entry (RKE)
transmitter or the key from outside
the vehicle. Use the door lock knob
or switch from inside the vehicle.

Traction Control System
(TCS)/StabiliTrak®Light
This light comes on briefly while
starting the vehicle.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light then goes off.
If the light comes on and stays
on while driving, there could be a
problem with the TCS/StabiliTrak
system and the vehicle might need
service. When this warning light is
on, the TCS/StabiliTrak system is
off and does not limit wheel spin.
The light flashes if the system is
active and is working to assist the
driver with directional control of the
vehicle in difficult driving conditions.
Engine Coolant
Temperature Warning
Light
The engine coolant temperature
warning light comes on briefly when
the vehicle is started.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light then goes off.
If the light comes on and stays
on while driving, the vehicle may
have a problem with the cooling
system. Stop and turn off the
vehicle to avoid damage to the
engine. A warning chime sounds
when this light is on.
SeeEngine Overheating on
page 10‑23 for more information.
Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the vehicle is
in ON/RUN. It provides information
about tire pressures and the TPMS.
When the Light is On Steady
This indicates that one or more
of the tires are significantly
underinflated.
A message in the Driver Information
Center (DIC) may also display.
SeeTire Messages on page 5‑52
for more information. Stop as soon
as possible, and inflate the tires to
the pressure value shown on the
Tire and Loading Information Label.
See Tires on page 10‑48 for more
information.

Engine Cooling System
Messages
ENGINE OVERHEATED —
REDUCE SPEED
This message displays when the
engine coolant temperature or
engine oil is too hot. Reduce speed
and allow the vehicle to cool down.
ENGINE OVERHEATED —
TURN VEHICLE OFF
This message displays and a
continuous chime sounds if the
engine cooling system reaches
unsafe temperatures for operation.
Stop and turn off the vehicle as
soon as it is safe to do so to avoid
severe damage. This message
clears when the engine has cooled
to a safe operating temperature.
ENGINE RUNNING DUE TO
TEMPERATURE
This message displays when the
high voltage battery is charged but
the engine has to come on because
of the outside temperature or high
voltage battery temperature.

Vehicle Care 10-19
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 temperature rises above this
temperature, the battery cooling
system turns on the air conditioning
compressor and cools the coolant
until the correct temperature is
reached. If the temperature falls
below this temperature, a high
voltage heater, located in the
battery, heats the coolant until the
correct temperature is reached.
What to Use
The high voltage battery coolant
reservoir in the vehicle is filled
with a 50/50 mixture of DEX-COOL
engine coolant and deionized water.
If using this mixture, nothing else
needs to be added.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The high voltage battery
coolant reservoir is located
on the passenger side of the
engine compartment. SeeEngine
Compartment Overview on
page 10‑10 for more information
on location.Check to see if coolant is visible
in the high voltage battery coolant
reservoir. If coolant is visible but the
coolant level is below the cold fill
line, there could be a leak in the
cooling system.
The high voltage battery coolant
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.
If the temperature rises above
this temperature, the electric
engine 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 a 50/50 mixture
of DEX-COOL engine coolant
and deionized water. If using this
mixture, nothing else needs to
be added.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The power electronics and
charger modules coolant reservoir
is located on the driver side of the
engine compartment. SeeEngine
Compartment Overview on
page 10‑10 for more information
on location.
Check to see if coolant is visible in
the power electronics and charger
modules coolant reservoir. If coolant
is visible but the coolant level is
below the cold fill line, there could
be a leak in the cooling system.
The power electronics and charger
modules coolant should only be
serviced by a qualified technician.
