The climate control system will use the
previous settings during a remote start. The
rear defog may come on during remote
start based on cold ambient conditions. The
rear defog indicator light does not come on
during a remote start.
Laws in some local communities may restrict
the use of remote starters. For example,
some laws require a person using remote
start to have the vehicle in view. Check local
regulations for any requirements.
If the vehicle is low on energy, do not use
the remote start feature. The vehicle may
run out of energy.
The RKE transmitter range may be less while
the vehicle is running.
Other conditions can affect the performance
of the transmitter. SeeRemote Keyless Entry
(RKE) System 07.
Remote Starting the Vehicle
To remote start the vehicle:
1. Press and release
Qon the RKE
transmitter.
2. Immediately press and hold
/for at
least four seconds or until the turn
signal lamps flash. 3. After entering the vehicle during a
remote start, press POWER
Owith the
brake pedal applied to start the vehicle
and operate as normal.
Remote start will automatically shut off
after 20 minutes unless a time extension
is done.
When the vehicle starts, the parking lamps
will turn on. Remote start run time can be
extended.
Extending Vehicle Run Time
The vehicle run time can also be extended
by another 20 minutes, if after 30 seconds
and during the first 20 minutes Steps 1 and
2 are repeated while the vehicle is running.
This provides a total of 40 minutes.
The remote start can only be extended once.
A maximum of two remote starts, or a
single start with an extension, are allowed
between ignition cycles using POWER
O.
For additional remote starts, turn the vehicle
on with the transmitter in the vehicle.
Canceling Remote Start
To cancel a remote start, do any of the
following:
.Press and hold/until the parking lamps
turn off.
.Turn on the hazard warning flashers.
.Press POWEROwith the brake pedal
applied, then press POWER
Oagain to
turn the vehicle off.
Conditions in Which Remote Start Will
Not Work
The remote vehicle start feature will not
operate if:
.The RKE transmitter is in the vehicle.
.The ignition is on.
.The hood is not closed.
.The hazard warning flashers are on.
.The electric drive unit coolant
temperature is too high.
.Two remote vehicle starts, or a single
remote start with an extension, have
already been used.
.The vehicle is not in P (Park).

Cooling System
It is not necessary to regularly check coolant
unless a leak is suspected or an unusual
noise is heard. A coolant loss could indicate
a problem. Have it inspected and repaired
by your dealer.
The following explains the cooling systems
and how to check coolant levels.
.High Voltage Battery
.Single Power Inverter Module (SPIM),
Accessory Power Module (APM), and
Charger Module
.Cabin Heating
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
outside the battery on a cradle, heats the
coolant until the correct temperature is
reached.
Single Power Inverter Module (SPIM),
Accessory Power Module (APM), and
Charger Module
The SPIM, APM, and charger module are
cooled using a separate coolant loop. These
modules are kept below a maximum
temperature. If the temperature rises above
this temperature, the electric cooling fan will
turn on to cool the coolant.
Cabin Heating
Cabin heating is maintained by coolant
heated by the Coolant Heater Control
Module (CHCM), separate from the power
electronics and battery coolant loops. This
module heats the coolant based on
temperature inputs from the cabin climate
control systems.
Hybrid Cooling System Pressure Caps
The hybrid cooling system reservoirs have
tamper resistant pressure caps. The coolant
should only be serviced by a qualified
technician.
Checking Coolant
The coolant needs to be replaced at the
appropriate interval. See Maintenance
Schedule 0276.
The coolant reservoirs are in the underhood
compartment. See Underhood Compartment
Overview 0220.

1. Park on a level surface and turn thevehicle off.
2. After the system has completely cooled, check that the coolant level is at the cold
fill mark on the reservoirs.
3. If the coolant level is not visible or needs to be adjusted within the reservoirs,
contact your dealer.
Washer Fluid
What to Use
When windshield washer fluid is needed, be
sure to read the manufacturer's instructions
before use. If operating the vehicle in an
area where the temperature may fall below
freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
Open the cap with the washer symbol on it.
Add washer fluid until the tank is full. See
Underhood Compartment Overview 0220 for
reservoir location.
Caution
.Do not use washer fluid that contains
any type of water repellent coating.
This can cause the wiper blades to
chatter or skip, and may also clog the
washer nozzle.
(Continued)
Caution (Continued)
.Do not use engine coolant (antifreeze)
in the windshield washer. It can
damage the windshield washer system
and paint.
.Do not mix water with ready-to-use
washer fluid. Water can cause the
solution to freeze and damage the
washer fluid tank and other parts of
the washer system.
.When using concentrated washer fluid,
follow the manufacturer instructions
for adding water.
.Fill the washer fluid tank only
three-quarters full when it is very cold.
This allows for fluid expansion if
freezing occurs, which could damage
the tank if it is completely full.
Brakes
Disc brake linings have built-in wear
indicators that make a high-pitched warning
sound when the brake linings are worn and
new linings are needed. The sound can come
and go or can be heard all the time when
the vehicle is moving, except when applying
the brake pedal firmly.
