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 305). The
luggage compartment covers need to be
removed in order to access the reservoirs.
See Installing and Removing the
Luggage Compartment Cover (page 278).

Maintenance
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 392).
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 346).
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.
