The fuel door release
button is located on the
instrument panel to the
left of the steering wheel.
Push the button to release
the fuel door.
There is also a manual
fuel door release tab.
It is located against the
upper trim in the rear
compartment on the driver
side of the vehicle. Pull the
tab to release the fuel door.To remove the fuel cap, turn it slowly counterclockwise.
While refueling, let the cap hang by the tether below
the fuel ll opening.
{CAUTION:
Fuel can spray out on you if you open the fuel cap
too quickly. If you spill fuel and then something
ignites it, you could be badly burned. This spray
can happen if the tank is nearly full, and is more
likely in hot weather. Open the fuel cap slowly and
wait for any hiss noise to stop. Then unscrew the
cap all the way.

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 rmly.
{CAUTION:
The brake wear warning sound means that soon
the brakes will not work well. That could lead to an
accident. 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 rst 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.
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.Front

Brake Rotor Protector
{CAUTION:
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.
5-48

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/retailer.
Brake Pedal Travel
See your dealer/retailer 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.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. The vehicle
was designed and tested with top-quality brake parts.
When parts of the braking system are replaced — for
example, when the brake linings wear down and new
ones are installed — be sure to get new approved
replacement parts. If this is not done, the brakes might
not work properly. For example, if someone puts in
brake linings that are wrong for the vehicle, the balance
between the front and rear brakes can change — for the
worse. The braking performance expected can change in
many other ways if the wrong replacement brake parts
are installed.
5-49

To replace a high-beam or front parking/turn signal/
DRL bulb:
1. Turn the wheel to allow access to the wheel well.
2. Remove the three outer fasteners to move the
access panel back.
3. Remove the outer cover to expose the high-beam
headlamp bulb socket.4. Remove the headlamp
bulb by releasing 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 and reattach to the bulb socket.
Replace the front parking/turn signal bulb by turning
the bulb socket clockwise.
7. Reverse the Steps 2 through 4 to reinstall.

Low-Prole Performance Tire
The original equipment tires on your vehicle are
classied as low-prole performance tires. These
tires are designed for very responsive driving on
wet or dry pavement. You may also notice more
road noise with low-prole tires and that they tend
to wear faster.
Notice:If the vehicle has low-prole tires,
they are more susceptible to damage from road
hazards or curb impact than standard prole
tires. Tire and/or wheel assembly damage can
occur when coming into contact with road
hazards like, potholes, or sharp edged objects,
or when sliding into a curb. The vehicle
warranty does not cover this type of damage.
Keep tires set to the correct ination pressure
and, when possible avoid contact with curbs,
potholes, and other road hazards.
Winter Tires
If you expect to drive on snow or ice covered roads
often, you may want to get winter tires for your vehicle.
All season tires provide good overall performance
on most surfaces but they may not offer the traction
you would like or the same level of performance
as winter tires on snow or ice covered roads.
Winter tires, in general, are designed for increased
traction on snow and ice covered roads. With winter tires,
there may be decreased dry road traction, increased road
noise, and shorter tread life. After switching to winter
tires, be alert for changes in vehicle handling and braking.
See your dealer/retailer for details regarding winter tire
availability and proper tire selection. Also, seeBuying
New Tires on page 5-78.
If you choose to use winter tires:
Use tires of the same brand and tread type on all
four wheel positions.
Use only radial ply tires of the same size,
load range, and speed rating as the original
equipment tires.
Winter tires with the same speed rating as your original
equipment tires may not be available for H, V, W, Y,
and ZR speed rated tires. If you choose winter tires with
a lower speed rating, never exceed the tire’s maximum
speed capability.

(G) Maximum Cold Ination Load Limit:Maximum load that can be carried and the
maximum pressure needed to support that load.
Tire Size
The following illustration shows an example of a
typical passenger (p-metric) vehicle tire size.
(A) Passenger (P-Metric) Tire
:The United States
version of a metric tire sizing system. The letter P
as the rst character in the tire size means a
passenger vehicle tire engineered to standards
set by the U. S. Tire and Rim Association.
(B) Tire Width
:The three-digit number indicates
the tire section width in millimeters from sidewall
to sidewall.(C) Aspect Ratio
:A two-digit number that
indicates the tire height-to-width measurements.
For example, if the tire size aspect ratio is 60, as
shown in item C of the illustration, it would mean
that the tire’s sidewall is 60 percent as high as it
is wide.
(D) Construction Code
:A letter code is used to
indicate the type of ply construction in the tire. The
letter R means radial ply construction; the letter D
means diagonal or bias ply construction; and the
letter B means belted-bias ply construction.
(E) Rim Diameter
:Diameter of the wheel in
inches.
(F) Service Description
:These characters
represent the load range and speed rating of the
tire. The load index represents the load carry
capacity a tire is certied to carry. The load index
can range from 1 to 279. The speed rating is the
maximum speed a tire is certied to carry a load.
Speed ratings range from A to Z.
