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.
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.
The cooling system allows the
vehicle to maintain the correct
working temperature.Checking Coolant
The coolant needs to be
replaced at the appropriate
interval. See Maintenance
Schedule
0376.
The coolant reservoir is in the
underhood compartment. See
Underhood Compartment
Overview 0312.
To access the coolant
reservoir under the hood, the
right side access cover needs
to be removed. 1. Park on a level surface and turn the vehicle off.
2. Open the hood. See Hood 0310.
3. The coolant reservoir is
under a cover and side
extension/shield in the
underhood compartment.
Unclip the right side of the
shield and remove the right
side access cover.

Battery - North
America
This vehicle has a high voltage
battery and a standard 12-volt
battery.
See your dealer if either the
12-volt or high voltage battery
needs service.
12–Volt Battery
The original equipment battery
is maintenance free. Do not
remove the cap and do not
add fluid.
Refer to the replacement
number shown on the original
battery label when a new
12-volt battery is needed. The
vehicle has an Absorbent
