CHECKING THE COOLANT WARNING:
Do not remove the
coolant reservoir cap when the vehicle
is on or the cooling system is hot. Wait
10 minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury. WARNING:
Do not put coolant in
the windshield washer reservoir. If
sprayed on the windshield, coolant could
make it difficult to see through the
windshield. WARNING:
Do not add coolant
further than the MAX mark.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
Your vehicle has a battery cooling system
and a motor electrical cooling system. See
Under Hood Overview
(page 303). The
luggage compartment covers need to be
removed in order to access the reservoirs.
See
Installing and Removing the
Luggage Compartment Cover (page 277). When the electric motor is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 390).
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between
-29–-35°F (-34–-37°C).
Check coolant concentration using a
refractometer. We do not recommend the
use of hydrometers or coolant test strips
for measuring coolant concentration.
Adding Coolant
It is very important to use prediluted
coolant approved to the correct
specification in order to avoid plugging the
small passageways in the electric motor
cooling system. See
Cooling System
Capacity and Specification (page 344).
Do not mix different colors or types of
coolant in your vehicle. Mixing of coolants
or using an incorrect coolant may harm the
electric motor or cooling system
components and may cause damage that
the vehicle warranty may not cover.
Note: Automotive fluids are not
interchangeable.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the electric
motor cooling or heating systems.

Note:
If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water. See
Cooling System Capacity and
Specification (page 344). Using water that
has not been deionized could contribute to
deposit formation, corrosion and plugging
of the small cooling system passageways.
Note: Coolants marketed for all makes and
models might not meet our specifications
and could cause damage to the cooling
system. Resulting component damage
could void the vehicle warranty.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
To top up the coolant level do the
following:
1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
2. Add prediluted coolant approved to the correct specification. See Cooling
System Capacity and Specification
(page 344).
3. Add enough prediluted coolant to reach the correct level.
4. Replace the coolant reservoir cap. Turn
the cap clockwise until it contacts the
hard stop.
5. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted coolant to bring the coolant
level to the correct level.
If you have to add more than
1.1 qt (1 L) of
coolant per month, have your vehicle
checked as soon as possible. Operating
your vehicle with a low level of coolant can
result in overheating and possible electric
motor damage. In case of emergency, you can add a large
amount of water without coolant in order
to reach a vehicle service location. In this
instance, have qualified personnel do the
following as soon as possible:
1. Drain the cooling system.
2. Chemically clean the coolant system.
3. Refill with coolant.
Water alone, without coolant, can cause
damage from corrosion, overheating or
freezing.
Do not use the following as a coolant
substitute:
•
Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
Alcohol and other liquids can cause
damage from overheating or freezing.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of
the coolant.
Recycled Coolant
We do not recommend the use of recycled
coolant, as an approved recycling process
is not yet available.
Dispose of used coolant in an appropriate
manner. Follow your community's
regulations and standards for recycling and
disposing of automotive fluids.

Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60%
provides improved freeze point
protection.
• Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and may
cause damage to the electric motor.
If you drive in extremely hot climates:
• You can decrease the coolant
concentration to 40%.
• A coolant concentration of 40%
provides improved overheat protection.
• Coolant concentrations below 40%
decrease the overheat and corrosion
protection characteristics of the
coolant and may cause damage to the
electric motor.
Coolant Change
Change the coolant at specific mileage
intervals listed in the scheduled
maintenance information. Add prediluted
coolant approved to the correct
specification. See Cooling System
Capacity and Specification (page 344).
AUTOMATIC TRANSMISSION
FLUID CHECK
If required, have an authorized dealer check
and change the transmission fluid at the
correct service interval. See
Scheduled
Maintenance (page 390).
The automatic transmission does not have
a transmission fluid dipstick. Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission
does not consume fluid. However, if you
notice a sign of leaking fluid, contact an
authorized dealer.
Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials may
affect transmission operation and result
in damage to internal transmission
components.
12V BATTERY
CHANGING THE 12V BATTERY
If the 12 volt battery needs servicing, see
your authorized dealer.
CHARGING THE 12V BATTERY
Your vehicle has a high voltage to low
voltage energy transfer feature that keeps
the 12 volt battery charged by the high
voltage battery. If the 12 volt battery level
is low, the high voltage battery transfers
energy to the 12 volt battery when the
vehicle is off.
12V BATTERY –
TROUBLESHOOTING
12V BATTERY – WARNING LAMPS
If it illuminates when the green
ready to drive indicator is
activated, this indicates your
vehicle requires service. Have your vehicle
checked as soon as possible.
