Hydroplaning
Hydroplaning is dangerous. Water
can build up under the vehicle's
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
. Pass with caution.
. Keep windshield wiping
equipment in good shape.
. Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper
tread depth. See Tires0272.
. Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. See
“Mountain Mode” underDriver
Selected Operating Modes 0188.
Tips include:
. Keep the vehicle serviced and in
good shape.
. Check all fluid levels and brakes,
tires, cooling system, and
electric drive unit.
. Keep the vehicle in gear when
going down steep or long hills.
{Warning
Coasting downhill in N (Neutral)
or with the vehicle turned off is
dangerous. The brakes will have
to do all the work of slowing down
the vehicle and could become too
hot. Hot brakes may not be able
to slow the vehicle enough to
maintain speed and control. You
could crash. Always have the
(Continued)
Warning (Continued)
vehicle running and in gear
(preferably LOW range) when
going downhill. This will allow the
electric drive unit to assist in
slowing and maintaining speed.
. Drive at speeds to keep the
vehicle in its own lane. Do not
swing wide or cross the
center line.
. Be alert on top of hills.
Something could be in your lane
(e.g., stalled car, accident).
. Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and
the road creates less traction or
grip, so drive carefully. Wet ice can
occur at about 0 °C (32 °F) when

Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment: .
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0245.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a loop.
SeeEngine Compartment Overview
0 242 for the location of the engine
oil dipstick.

248 Vehicle Care
Cooling System (Engine)
1. Engine Coolant Surge Tankand Pressure Cap
2. Engine Cooling Fans (Out of View)
{Warning
The electric fans under the hood
can start up even when the
engine is not running and can
cause injury. Keep hands,
clothing, and tools away from any
underhood electric fan. If the coolant inside the coolant
surge tank is boiling, do not do
anything else until it cools down.
The vehicle should be parked on a
level surface.
The coolant level should be up to
the cold fill line. If it is not, there
might be a leak at the radiator
hoses, heater hoses, radiator, water
pump, or somewhere else in the
cooling system.
{Warning
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the vehicle if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
If there seems to be no leak, with
the engine on, check to see if the
cooling fans are running. If the
engine is overheating, the fans should be running. If it is not, the
vehicle needs service. Turn off the
vehicle.
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 required to
be filled with a 50/50 mixture of
DEX-COOL
®engine coolant and
ProCarManuals.com

Vehicle Care 249
deionized water. If using this
mixture, nothing else needs to be
added.
The coolant needs to be replaced at
the appropriate interval. See
Maintenance Schedule0318.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The high voltage battery coolant
reservoir is in the engine
compartment. See Engine
Compartment Overview 0242.
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.
These modules are kept below a
maximum temperature. If the
temperature rises above this
temperature, the electric cooling
fans will turn on to cool the coolant.
What to Use
The coolant reservoir for these
modules is filled with a 50/
50 mixture of DEX-COOL engine
coolant and deionized water. See
Recommended Fluids and
Lubricants 0327. If using this
mixture, nothing else needs to be
added.
The coolant needs to be replaced at
the appropriate interval. See
Maintenance Schedule 0318.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The reservoir is in the engine
compartment. See Engine
Compartment Overview 0242.
