When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter
at the scheduled maintenance
intervals and replace them at
the first oil change after each
80 000 km (50,000 mile) interval.
SeeScheduled Maintenance on
page 11‑2 for more information.
If driving in dusty/dirty conditions,
inspect the filter at each engine oil
change. How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter,
remove the filter from the vehicle
and lightly shake the filter to release
loose dust and dirt. If the filter
remains caked with dirt, a new filter
is required.
To inspect or replace the engine air
cleaner/filter:
1. Open the hood. See
Hood on
page 10‑9.

WARNING (Continued)
SeeOverheated Engine
Protection Operating Mode on
page 10‑35 for information on
driving to a safe place in an
emergency.
If No Steam is Coming from
the Engine
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day
.Stops after high-speed driving
.Idles for long periods in traffic If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest
temperature and to the highest
fan speed. Open the windows as
necessary.
3. If in a traffic jam, shift to N (Neutral) while stopped. If it is
safe to do so, pull off the road,
shift to P (Park) or N (Neutral)
and let the engine idle.
If the temperature overheat gauge
is no longer in the overheat zone
or an overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle slowly
for about 10 minutes. Keep a safe
vehicle distance from the vehicle in
front. If the warning does not come
back on, continue to drive normally.
If the warning continues, pull
over, stop, and park the vehicle
right away. If there is no sign of steam, idle
the engine for three minutes
while parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see
“Overheated
Engine Protection Operating Mode”
next in this section.
Overheated Engine
Protection
Operating Mode
This emergency operating mode
lets the vehicle be driven to a
safe place, up to 80 km (50 mi),
in an emergency situation. If an
overheated engine condition exists
and the messages COOLANT
OVER TEMPERATURE and
REDUCED ENGINE POWER are
displayed, along with the check
engine light, an overheat protection
mode which alternates firing groups
of cylinders helps prevent engine
damage. In this mode, there is a
significant loss in power and engine
performance.

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.

Headlamp Aiming
Headlamp aim has been preset at
the factory and should need no
further adjustment.
However, if the vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to
the low-beam headlamps may be
necessary if oncoming drivers flash
their high-beam headlamps at you
(for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
the vehicle be taken to the dealer
for service.
Bulb Replacement
For the proper type of replacement
bulbs, seeReplacement Bulbs on
page 10‑50.
For any bulb‐changing procedure
not listed in this section, contact
your dealer.
Halogen Bulbs
{WARNING
Halogen bulbs have pressurized
gas inside and can burst if you
drop or scratch the bulb. You or
others could be injured. Be sure
to read and follow the instructions
on the bulb package.
High Intensity Discharge
(HID) Lighting
{WARNING
The low beam high intensity
discharge lighting system
operates at a very high voltage.
If you try to service any of the
system components, you could
be seriously injured. Have your
dealer or a qualified technician
service them.
The vehicle may have HID
headlamps. After an HID headlamp
bulb has been replaced, you may
notice that the beam is a slightly
different shade than it was originally.
This is normal.

to be replaced, see your dealer.
SeeHigh Intensity Discharge (HID)
Lighting on page 10‑48 for more
information. To replace a high-beam or front
parking/turn signal bulb:
1. Turn the wheel to allow access
to the wheel well.2. Remove the three outerfasteners to move the access
panel back.
3. Remove the outer cover to expose the high-beam headlamp
bulb socket.
4. Remove the headlamp bulb byreleasing the outer tabs from the
socket.
5. Remove the front parking/turn signal bulb by turning the bulb
socket counterclockwise.
6. Replace the high-beam headlamp bulb with a new bulb

Fuses and circuit breakers protect
the following in the vehicle:
.Headlamp Wiring
.Windshield Wiper Motor
.Power Windows and Other
Power Accessories
Replace a bad fuse with a new one
of the identical size and rating.
If there is a problem on the road
and a fuse needs to be replaced,
the same amperage fuse can be
borrowed. Choose some feature of
the vehicle that is not needed to use
and replace it as soon as possible.
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have
the headlamp wiring checked right
away if the lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using
the windshield wipers.
If the overload is caused by an
electrical problem and not snow
or ice, be sure to get it fixed.
Fuses and Circuit
Breakers
The wiring circuits in the vehicle
are protected from short circuits
by a combination of J-Case fuses,
mini-fuses and circuit breakers.
This greatly reduces the chance of
fires caused by electrical problems. Look at the silver-colored band
inside the fuse. If the band is broken
or melted, replace the fuse. Be sure
you replace a bad fuse with a new
one of the identical size and rating.
If you ever have a problem on the
road and do not have a spare fuse,
you can borrow one that has the
same amperage. Just pick some
feature of the vehicle that you can
get along without
—like the radio
or cigarette lighter —and use its
fuse, if it is the correct amperage.
Replace it as soon as you can.
Vehicles with the ZR‐1 package
have an intercooler relay located on
the fan shroud. See your dealer.
Vehicles with the ZR‐1 package also
have a fuel system mini-fuse. It is
located near the battery in the
battery storage compartment in
the rear of the vehicle.
