Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There is an engine coolant
temperature gauge on the
instrument panel cluster.
SeeEngine Coolant Temperature
Gauge on page 5‑15. The vehicle
may also display a COOLANT
OVER TEMPERATURE message
on the Driver Information
Center (DIC). See Engine Cooling
System Messages on page 5‑39
for more information.
If the decision is made not to lift the
hood but to get service help right
away. See Roadside Assistance
Program (United States and
Canada) on page 13‑8 orRoadside
Assistance Program (Mexico) on
page 13‑10.
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 fan is running. If the engine
is overheating, the fan should be
running. If it is not, do not continue
to run the engine and have the
vehicle serviced.
Notice:
Engine damage from
running your engine without
coolant is not covered by the
vehicle warranty. See Overheated
Engine Protection Operating
Mode for information on driving
to a safe place in an emergency.
Notice: If the engine catches fire
while driving with no coolant, the
vehicle can be badly damaged.
The costly repairs would not be
covered by the vehicle warranty.
See Overheated Engine
Protection Operating Mode on
page 10‑35 for information on
driving to a safe place in an
emergency.
If Steam is Coming from the
Engine
{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. 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
vehicles engine is overheated,
the liquids in it can catch fire.
You or others could be badly
burned. Stop the engine if it
overheats, and get out of the
vehicle until the engine is cool.

Brakes
Brake Wear (Except ZR1)
This vehicle has disc 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 be
heard all the time 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.Notice:
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.
Brake linings should always be
replaced as complete axle sets.
Brake Wear (ZR1 Only)
The ZR1 model does not have
built-in brake pad wear indicators
and periodic visual inspection of the
brake pads is required to determine
when to replace the brake pads. Notice:
Continuing to drive with
worn-out brake pads could result
in costly brake repair.
.Make sure that the brakes have
been given sufficient time to cool
and then set the park brake.

Front
.Brake pads can be visually
inspected through the wheel by
inspecting the outer brake pads
at each wheel.
.Brake pads should be replaced
when worn to two mm of pad
thickness. New pads are 10 mm
thick.
.In addition, brake pad inspection
is required any time the tires are
removed.
The ZR1 also has an electronic
brake pad wear sensor system.
When pads are worn, the CHANGE
BRAKE PADS message displays
in the Driver Information Center.
SeeBrake System Messages on
page 5‑36.
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.
Brake linings should always be
replaced as complete axle sets. Brake Rotor Wear
ZR1 models have ceramic brake
rotors. Rotors should be visually
inspected whenever the brake pads
are replaced. Rotors also need to
be weighed before brake pads are
replaced to confirm that the rotor
mass is greater than the wear‐out
mass printed on the rotor. The rotor
can be reused if the weight of the
rotor is above the mass limit. Rotor
inspection and weighing methods
can be found in the service manual.
See
Service Publications Ordering
Information on page 13‑15.

Brake Rotor Protector
{WARNING
Ceramic rotors will be very hot
after operation and touching them
may cause burns. Be sure brake
system is completely cool prior to
installation of protector, or coming
in contact with them.
Notice: Rotors may be chipped
if hard contact is made with the
wheel during wheel installation
or removal. Always use the rotor
protectors. Be sure to carefully
follow wheel removal and
installation instructions.
A rotor protector should always be
installed before any wheel removal.
The protector can be installed by
feeding it through the wheel spokes
and slipping it over the outer edge
of the rotor. Leave the protector in
place, over the rotor edge, until
the wheel is re‐installed. Rotor
protectors are available through
your dealer.
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 might
be required.
Brake Adjustment
Every brake stop, the disc brakes
automatically adjust for wear.

Notice:
.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.

Rear Axle
When to Check Lubricant
It is not necessary to regularly
check rear axle fluid unless a leak
is suspected or an unusual noise is
heard. A fluid loss could indicate a
problem. Have it inspected and
repaired.
How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.If the level is below the bottom of
the fill plug hole, some lubricant will
need to be added. Add enough
lubricant to raise the level to the
bottom of the fill plug hole.
What to Use
To add lubricant when the level
is low or to completely refill after
draining, see
Recommended Fluids
and Lubricants on page 11‑6. Then
fill to the bottom of the fill plug hole
with the required lubricant.
