Some gasolines, mainly high octane
racing gasolines, can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). Do not use
gasolines and/or fuel additives with
MMT as they will reduce spark plug
life and affect emission control system. The malfunction indicator
lamp may turn on. If this occurs, see
your dealer for service.
California Fuel
Requirements
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications. See

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

11683523) - 2018 - CRC - 7/10/17
194 Vehicle Care
After work is done on the brake
hydraulic system, make sure the
level is above the MIN but not over
the MAX mark.
If the brake fluid is below the MIN
line, the brake warning light will
illuminate. Add brake fluid up to the
MAX line.
What to Add
Use only new DOT 3 brake fluid
from a sealed container. See
Recommended Fluids and
Lubricants0257.
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it. This
helps keep dirt from entering the
reservoir.
{Warning
With the wrong kind of fluid in the
brake hydraulic system, the
brakes might not work well. This
could cause a crash. Always use
the proper brake fluid.
Caution
. Using the wrong fluid can
badly damage brake
hydraulic system parts. For
example, just a few drops of
mineral-based oil, such as
engine oil, in the brake
hydraulic system can
damage brake hydraulic
system parts so badly that
they will have to be
replaced. Do not let
someone put in the wrong
kind of fluid.
. If brake fluid is spilled on
the vehicle's painted
surfaces, the paint finish
can be damaged. Be careful
not to spill brake fluid on the
vehicle. If you do, wash it off
immediately.

202 Vehicle Care
Summer Tires
This vehicle may come with high
performance summer tires. These
tires have a special tread and
compound that are optimized for
maximum dry and wet road
performance. This special tread and
compound will have decreased
performance in cold climates, and
on ice and snow. It is recommended
that winter tires be installed on the
vehicle if frequent driving at
temperatures below approximately
5 °C (40 °F) or on ice or snow
covered roads is expected. See
Winter Tires0201.
Caution
High performance summer tires
have rubber compounds that lose
flexibility and may develop
surface cracks in the tread area
at temperatures below −7 °C (20 °
F). Always store high
performance summer tires
indoors and at temperatures
(Continued)
Caution (Continued)
above−7 °C (20 °F) when not in
use. If the tires have been
subjected to −7 °C (20 °F) or less,
let them warm up in a heated
space to at least 5 °C (40 °F) for
24 hours or more before being
installed or driving a vehicle on
which they are installed. Do not
apply heat or blow heated air
directly on the tires. Always
inspect tires before use. See Tire
Inspection 0213.
All-Terrain Tires
This vehicle may have All-Terrain
Tires. These tires provide good
performance on most road surfaces,
weather conditions, and for off-road
driving.
The tread pattern on these tires may
wear more quickly than other tires.
Consider rotating the tires more
frequently than at 8 000 km
(5,000 mi) intervals if irregular wear is noted when the tires are
inspected. See
Tire Inspection
0 213.
