Vehicle Care 10-19
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 when the vehicle
is moving, except when applying the
brake pedal firmly.
{ WarningThe 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 on page 12-2 .
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
in many other ways if the wrong
replacement brake parts are
installed or parts are improperly
installed.
Brake Fluid
The brake master cylinder reservoir
is filled with DOT 3 brake fluid. See
Engine Compartment Overview on
page 10-7 for the location of the
reservoir.
There are only two reasons why the
brake fluid level in the reservoir
might go down: .
The brake fluid level goes down
because of normal brake lining
wear. When new linings are
installed, the fluid level goes
back up.

{ CautionSpilling liquid on any electrical
component on the vehicle may
damage it. Always keep the
covers on any electrical
component.
Pull the fuse box cover to remove.
Push the fuse box cover to install. Wheels and Tires Tires Every new GM vehicle has
high-quality tires made by a
leading tire manufacturer. See
the warranty manual for
information regarding the tire
warranty and where to get
service. For additional
information refer to the tire
manufacturer.
{ Warning .
Poorly maintained and
improperly used tires are
dangerous. .
Overloading the tires can
cause overheating as a
result of too much flexing.
There could be a blowout
(Continued) Warning (Continued)
and a serious crash. See
Vehicle Load Limits on
page 9-9 . .
Underinflated tires pose
the same danger as
overloaded tires. The
resulting crash could
cause serious injury.
Check all tires frequently
to maintain the
recommended pressure.
Tire pressure should be
checked when the tires
are cold. .
Overinflated tires are more
likely to be cut, punctured,
or broken by a sudden
impact — such as when
hitting a pothole. Keep
tires at the recommended
pressure.

Vehicle Care 10-27Warning (Continued) .
Worn or old tires can
cause a crash. If the tread
is badly worn,
replace them. .
Replace any tires that
have been damaged by
impacts with potholes,
curbs, etc. .
Improperly repaired tires
can cause a crash. Only
the dealer or an
authorized tire service
center should repair,
replace, dismount, and
mount the tires. .
Do not spin the tires in
excess of 56 km/h
(35 mph) on slippery
surfaces such as snow,
mud, ice, etc. Excessive
spinning may cause the
tires to explode. All-Season Tires This vehicle may come with
all-season tires. These tires are
designed to provide good overall
performance on most road surfaces
and weather conditions. Original
equipment tires designed to meet
all-season requirements have MS
molded onto the sidewall. This
symbol can usually be found
following the size designation.
Consider installing winter tires on
the vehicle if frequent driving on
snow or ice-covered roads is
expected. All-season tires provide
adequate performance for most
winter driving conditions, but they
may not offer the same level of
traction or performance as winter
tires on snow or ice-covered roads.
See Winter Tires on page 10-27 .
Winter Tires This vehicle was not originally
equipped with winter tires. Winter
tires are designed for increased
traction on snow and ice-covered roads. Consider installing winter
tires on the vehicle if frequent
driving on ice or snow covered
roads is expected. See your dealer
for details regarding winter tire
availability and proper tire selection.
Also, see Buying New Tires on
page 10-41 .
With winter tires, there may be
decreased dry road traction,
increased road noise, and shorter
tread life. After changing to winter
tires, be alert for changes in vehicle
handling and braking.
If using 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.
Black plate (28,1)Chevrolet City Express Owner Manual (GMNA-Localizing-U.S./Canada-
7707496) - 2015 - CRC - 11/26/14
10-28 Vehicle Care Winter tires with the same speed
rating as the original equipment tires
may not be available for H, V, W, Y,
and ZR speed rated tires. If winter
tires with a lower speed rating are
chosen, never exceed the tire's
maximum speed capability.
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. We recommend
installing winter tires 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 Tires on
page 10-27 . 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 on
page 10-39 .
Tire Sidewall Labeling Useful information about a tire is
molded into the sidewall. The
examples show a typical
passenger vehicle and light
truck tire sidewall. Passenger (P-Metric) Tire
(1) Tire Size :
The tire size code
is a combination of letters and
numbers used to define a
particular tire's width, height,
aspect ratio, construction type,
and service description. See the
“ Tire Size ” illustration later in this
section for more detail.
(2) DOT (Department of
Transportation) :
The
Department of Transportation
(DOT) code indicates that the
tire is in compliance with the
Black plate (29,1)Chevrolet City Express Owner Manual (GMNA-Localizing-U.S./Canada-
7707496) - 2015 - CRC - 11/26/14
Vehicle Care 10-29U.S. Department of
Transportation Motor Vehicle
Safety Standards.
DOT Tire Date of
Manufacture :
The last four
digits of the TIN indicate the tire
manufactured date. The first two
digits represent the week
(01-52) and the last two digits,
the year. For example, the third
week of the year 2010 would
have a four-digit DOT date
of 0310.
(3) Tire Identification Number
(TIN) :
The letters and numbers
following the DOT code are the
Tire Identification Number (TIN).
The TIN shows the
manufacturer and plant code,
tire size, and date the tire was
manufactured. The TIN is
molded onto both sides of the
tire, although only one side may
have the date of manufacture. (4) Tire Ply Material :
The type
of cord and number of plies in
the sidewall and under the tread.
(5) Uniform Tire Quality
Grading (UTQG) :
Tire
manufacturers are required to
grade tires based on three
performance factors: treadwear,
traction, and temperature
resistance. For more
information, see Uniform Tire
Quality Grading on page 10-44 .
(6) Maximum Cold Inflation
Load Limit :
Maximum load that
can be carried and the
maximum pressure needed to
support that load. For
information on recommended
tire pressure see Tire Pressure
on page 10-35 and Vehicle Load
Limits on page 9-9 . Light Truck (LT-Metric) Tire
(1) Tire Size :
The tire size code
is a combination of letters and
numbers used to define a
particular tire's width, height,
aspect ratio, construction type,

Load Range.
(7) Service Description :
The
service description indicates the
load index and speed rating of a
tire. If two numbers are given as
in the example, 120/116, then
this represents the load index for
single versus dual wheel usage
(single/dual). The speed rating is
the maximum speed a tire is
certified to carry a load. This
does not apply to Goodyear
LT225/75R16 G949 RSA and
