most passenger car tires. The
Uniform Tire Quality Grading
(UTQG) system does not apply
to deep tread, winter tires,
compact spare tires, tires with
nominal rim diameters of
10 to 12 inches (25 to 30 cm),
or to some limited-production
tires.
While the tires available on
General Motors passenger cars
and light trucks may vary with
respect to these grades, they
must also conform to federal
safety requirements and
additional General Motors Tire
Performance Criteria (TPC)
standards.
Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width. For
example:Treadwear 200 Traction AA
Temperature A
All Passenger Car Tires Must
Conform to Federal Safety
Requirements In Addition To
These Grades.
Treadwear
The treadwear grade is a
comparative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course. For example, a tire
graded 150 would wear one and
one-half (1½) times as well on
the government course as a tire
graded 100. The relative
performance of tires depends
upon the actual conditions of
their use, however, and may
depart significantly from the
norm due to variations in driving
habits, service practices and
differences in road
characteristics and climate.Traction
The traction grades, from
highest to lowest, are AA, A, B,
and C. Those grades represent
the tire's ability to stop on wet
pavement as measured under
controlled conditions on
specified government test
surfaces of asphalt and
concrete. A tire marked C may
have poor traction performance.
Warning: The traction grade
assigned to this tire is based on
straight-ahead braking traction
tests, and does not include
acceleration, cornering,
hydroplaning, or peak traction
characteristics.
Temperature
The temperature grades are A
(the highest), B, and C,
representing the tire's resistance
to the generation of heat and its
ability to dissipate heat when
tested under controlled
conditions on a specified indoor

Warning (Continued)
Use another type of traction
device only if its manufacturer
recommends it for the vehicle's
tire size combination and road
conditions. Follow that
manufacturer's instructions. To
avoid vehicle damage, drive slow
and readjust or remove the
traction device if it contacts the
vehicle. Do not spin the wheels.
If traction devices are used, install
them on the front tires.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires
are maintained properly. SeeTires
0 261. If air goes out of a tire, it is
much more likely to leak out slowly.
But if there is ever a blowout, here
are a few tips about what to expect
and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop, well off the
road, if possible.
A rear blowout, particularly on a
curve, acts much like a skid and
may require the same correction as
used in a skid. Stop pressing the
accelerator pedal and steer to
straighten the vehicle. It may be
very bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.
{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
underinflated or flat may cause a
blowout and a serious crash.
Never attempt to re-inflate a tire
that has been driven on while
severely underinflated or flat.
Have your dealer or an authorized
tire service center repair or
replace the flat tire as soon as
possible.
{Warning
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the
appropriate safety equipment and
training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could
be badly injured or killed if the
vehicle slips off the jack. If a jack
is provided with the vehicle, only
use it for changing a flat tire.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place, well off the road,
if possible. Turn on the hazard
warning flashers. See Hazard
Warning Flashers 0149.
{Warning
Changing a tire can be
dangerous. The vehicle can slip
off the jack and roll over or fall

4. Make the final connection to aheavy, unpainted metal engine
part or to the remote
negative (−) terminal on the
other vehicle with the run-down
battery.
5. Press POWER
Oto start the
Volt. This will wake up the
electronics on the Volt. The
engine will only start if it is
needed.
6. Try to start the other vehicle that had the run-down battery.
If it will not start after a few
tries, it probably needs service.
Disconnecting the Jumper Cables 1. Disconnect the black negative (−) jumper cable from
the other vehicle that had the
run-down battery. Do not let the
other end of the cable touch
anything until after the
next step.
2. Disconnect the black negative (−) jumper cable from
the Volt. 3. Disconnect the red positive (+)
jumper cable from the Volt. Do
not let the other end of the
cable touch anything until after
the next step.
4. Disconnect the red positive (+) jumper cable from the other
vehicle.
5. Return the positive (+) and negative (−) terminal covers to
their original positions.
After starting the disabled vehicle
and removing the jumper cables,
allow it to idle for several minutes.
Towing the Vehicle
Caution
Incorrectly towing a disabled
vehicle may cause damage to the
vehicle. The disabled vehicle
should be towed on a flatbed car
carrier. Use care when there is
low ground clearance and/or
special equipment. Attempting to
pull the vehicle onto a flatbed
without following the proper steps
could damage the vehicle.
Use the tow eye for towing a
disabled vehicle or loading it onto a
flatbed car carrier. The tow eye
should not be used to recover a
vehicle from an off road situation.
Caution
Improper use of the tow eye can
cause vehicle damage. Use
caution and low speeds to
prevent damage to the vehicle.

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S/Canada/Mexico-
9159388) - 2016 - crc - 5/20/15
Vehicle Care 301
Consult your dealer or a
professional towing service if the
disabled vehicle must be towed.
To load a vehicle onto a flatbed
carrier:1. The vehicle must be on a flat surface.
2. The front tires must be properly inflated. If necessary, move a
rear tire to the front to replace
a flat or damaged tire.
If equipped, use the spare tire
to replace a flat or
damaged tire.
3. Remove the tow eye bolt from
the rear storage area. 4. Remove the front bumper tow
eye cover.
5. Screw the tow eye bolt into the bumper.
The tow cable can hook into
the tow eye bolt and pull the
vehicle onto the flatbed tow
truck.
6. Ramps are required for thefront fascia to clear the flatbed.
Caution
If ramps are not used, the front
fascia will come into contact with
the flatbed and may cause
damage. Always use ramps.
7. Use the proper nylon strap harnesses around the tires to
secure them to the flatbed car
carrier.
8. If the car is parked at an angle so that the front toe eye cannot
be accessed, wrap a tow strap
around both of the rear trailing
arms and pull the vehicle onto
a flat surface. Do not wrap the
tow strap around the rear
torque tube.

General Information
Your vehicle is an important
investment. This section describes
the required maintenance for the
vehicle. Follow this schedule to help
protect against major repair
expenses resulting from neglect or
inadequate maintenance. It may
also help to maintain the value of
the vehicle if it is sold. It is the
responsibility of the owner to have
all required maintenance performed.
Your dealer has trained technicians
who can perform required
maintenance using genuine
replacement parts. They have
up-to-date tools and equipment for
fast and accurate diagnostics. Many
dealers have extended evening and
Saturday hours, courtesy
transportation, and online
scheduling to assist with service
needs.
Your dealer recognizes the
importance of providing
competitively priced maintenance
and repair services. With trained
technicians, the dealer is the place
for routine maintenance such as oil changes and tire rotations and
additional maintenance items like
tires, brakes, batteries, and wiper
blades.
Caution
Damage caused by improper
maintenance can lead to costly
repairs and may not be covered
by the vehicle warranty.
Maintenance intervals, checks,
inspections, recommended fluids,
and lubricants are important to
keep the vehicle in good working
condition.
The Tire Rotation and Required
Services are the responsibility of the
vehicle owner. It is recommended to
have your dealer perform these
services every 12 000 km/7,500 mi.
Proper vehicle maintenance helps to
keep the vehicle in good working
condition, improves fuel economy,
and reduces vehicle emissions.
Because of the way people use
vehicles, maintenance needs vary.
