Caution
If the improper coolant mixture,
inhibitors, or additives are used in
the vehicle cooling system, the
engine could overheat and be
damaged. Too much water in the
mixture can freeze and crack
engine cooling parts. The repairs
would not be covered by the
vehicle warranty. Use only the
recommended engine coolant for
the cooling system. See
Recommended Fluids and
Lubricants 0257. Never dispose of engine coolant by
putting it in the trash, by pouring it
on the ground, or by pouring into
sewers, streams, or bodies of water.
Have the coolant changed by an
authorized service center, familiar
with legal requirements regarding
used coolant disposal. This will help
protect the environment and your
health.
Checking Engine Coolant
Level
{Warning
You can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene glycol
and it will burn if the engine parts
are hot enough. Do not spill
coolant on a hot engine.
Caution
This vehicle has a specific
coolant fill procedure. Failure to
follow this procedure could cause
the engine to overheat and be
severely damaged.
{Warning
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. Never turn
the cap when the cooling system,
including the surge tank pressure
cap, is hot. Wait for the cooling
system and surge tank pressure
cap to cool.
The vehicle must be on a level
surface when checking the coolant
level.

11683523) - 2018 - CRC - 7/10/17
Vehicle Care 189
Check the coolant level in the
reservoir when the engine is cold.
If the coolant level is below the MIN
level, add coolant to the MAX level.
If the reservoir is empty, check the
coolant level in the radiator when
the engine is cold. If there is
insufficient coolant in the radiator, fill
the radiator with coolant up to the
filler opening and also add it to the
reservoir up to the MAX level.
The vehicle contains long life
coolant. The life expectancy of the
factory-fill coolant is 168,000 km
(105,000 miles) or seven years.
Mixing any other type of coolant or
the use of non-distilled water willreduce the life expectancy of the
factory-fill coolant. Refer to the
Recommended Fluids and
Lubricants
0257 for more details.
The engine coolant reservoir is a
pressurized tank. When installing
the cap, tighten.
If the cooling system frequently
requires coolant, have it checked by
your dealer.
Changing Engine Coolant
A dealer can change the engine
coolant. The service procedure can
be found in the service manual. See
Service Publications Ordering
Information 0272.
Improper servicing can result in
reduced heater performance and
engine overheating.
{Warning
. To avoid the danger of
being scalded, never
change the coolant when
the engine is hot.
(Continued)
Warning (Continued)
.Never remove the radiator
or engine coolant reservoir
cap when the engine is hot.
Serious burns could be
caused by high pressure
fluid escaping from the
radiator.
. Avoid direct skin contact
with used coolant. If skin
contact is made, wash
thoroughly with soap or
hand cleaner as soon as
possible.
. Keep coolant out of the
reach of children and pets.
Engine coolant must be disposed of
properly. Check your local
regulations.

Engine Overheating
The vehicle has an engine coolant
temperature warning light on the
instrument cluster to warn of engine
overheating. SeeEngine Coolant
Temperature Warning Light 096.
If the decision is made not to lift the
hood when this warning appears,
but instead get service help right
away, see Roadside Assistance
Program 0267.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, the fans
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
See if the engine cooling fan speed
increases when idle speed is
doubled by pushing the accelerator
pedal down. If it does not, the
vehicle needs service. Turn off the
engine.Caution
Running the engine without
coolant may cause damage or a
fire. Vehicle damage would not be
covered by the vehicle warranty.
If Steam is Coming from the
Engine Compartment
{Warning
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the (Continued)
Warning (Continued)
engine if it overheats, and get out
of the vehicle until the engine
is cool.
Overheated Engine
Protection
Operating Mode
The engine has an engine
protection mode to reduce the
chance of damage if the coolant
temperature goes too high (for
example, when climbing steep
grades in high temperature with
heavy loads, such as when towing a
trailer). When the engine
temperature reaches a certain level:
.The engine coolant temperature
warning light will illuminate.
. Engine power may be reduced.
. The air conditioning cooling
function may be automatically
turned OFF for a short time (the
blower will continue to operate).

Vehicle Care 191
Engine power and under certain
conditions, vehicle speed will
decrease. Vehicle speed can be
controlled with the accelerator
pedal, but the vehicle may not
accelerate at the desired speed.
The transmission will downshift or
upshift as it reaches prescribed shift
points. You can also shift manually.
As driving conditions change and
engine coolant temperature is
reduced, vehicle speed can be
increased using the accelerator
pedal, and air conditioning cooling
function will automatically be turned
back ON.
If:1. The engine coolant temperature is not reduced.
2. The air conditioning cooling function does not turn
back ON.
3. The engine oil pressure low/ engine coolant temperature
high warning light illuminates,
this may indicate a malfunction.
Move the vehicle off the road in
a safe area and allow the engine to cool. If after checking
the oil and coolant, the oil
pressure low/engine coolant
temperature high warning light
remains on, do not continue to
drive. Call your dealer.
The malfunction indicator light may
also come on. If only it remains on,
you do not need to have the vehicle
towed, but have it inspected soon
by your dealer. For additional
information, see Malfunction
Indicator Lamp (Check Engine
Light) 091.
Washer Fluid
What to Use
When the vehicle needs windshield
washer fluid, 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 reservoir is full. See Engine
Compartment Overview 0181 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.

192 Vehicle Care
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 pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads 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.
{Warning
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Caution
Continuing to drive with worn-out
brake pads could result in costly
brake repair. Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear and
evenly tighten wheel nuts in the
proper sequence to torque
specifications. See
Capacities and
Specifications 0261.
Brake pads should be replaced as
complete sets.
Brake Pedal Travel
See your dealer if the brake pedal
does not return to normal height,
or if there is a rapid increase in
pedal travel. This could be a sign
that brake service may be required.
Replacing Brake System Parts
Always replace brake system parts
with new, approved replacement
parts. If this is not done, the brakes
may not work properly. The braking
performance expected can change
