Uniform Tire Quality Grading
is a tire information system devel
oped by the United States Nation
al Highway Traffic Safety Admin
istration (NHTSA) that is designed
to help buyers make relat ive com
parisons among tires . The UTQG
is not a safety rating and not a
guarantee that a tire will last for
a prescribed number of mi les
(kilometers) or perform in acer
tain way. It simply gives t ire buy
e rs add itional informa tion to
combine with other considera
tions, such as p rice, brand loya lty
and dealer recommendations . Un
der UTQG, tires are graded by t he
tire manufacturers in th ree areas:
treadwear, traction, and tempera
ture res istance. The UTQG infor
mation on the tires, molded into
the s idewalls .
U.S. DOT Tire Identification
Number (TIN)
This is the tire's "serial number".
It beg ins with the le tters "DO T"
and indicates that the tire meets
all federal standards . T he nex t
two numbers or letters indicate
the plant where it was manufac
tured , and the last fo ur numbers
represent the week and yea r of
manufacture. For examp le,
Wheels
DOT ... 2215 ...
means that the tire was produced
in the 22nd week o f 2015. The
other numbers are marketing co des that may or may not be used
by the t ire manufact urer. This in
formation is used to contact con sumers if a tire defec t req uires a
reca ll.
Vehicle capacity weight
means the rated cargo and lug
gage load plus 150 lbs . (68 k ilo
grams) t imes the vehicle's desig

Vehicle maximum load on the
tire
means that load on an ind iv idual
tire tha t is determined by dist rib
ut ing to eac h ax le its share of the
maximum loaded vehic le weight
and dividing by two.
Vehicle normal load on the tire
means that load on a n individual
tire that is determined by dist rib

increase the risk of the loss of
vehicle control.
- The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has
been overloaded can fail sud
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to
tal load being transported -
including the weight of a trail
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu
late the total weight of the pas
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload
ed.
Wheels
Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OCCU
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
~ page 227, fig. 190.
2.
Determine the combined
weight of the driver and pas
sengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver and passengers
from
" XXX " kilograms or "XXX "
pounds shown on the sticker
¢page 227, fig. 190.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex
ample, if the
" XXX " amount
equals
1400 lbs. and there will
be five
150 lbs. passengers in
your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs.
(1400-750 (5 X 150) = 650
lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle.

Emergency situations
Emergency situations
General
This chapter is intended for trained emergency crews and working personnel who have the nec
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
CD Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine con be started by con
necting it to the battery of another vehicle.
If the engine should fail to start because of a dis
charged or weak battery, the battery can be con
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently largecross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
clamps which are distinctly marked :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black.
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in
jury. Follow the instructions below for
safe
handling of your vehicle's battery.
-Always shield your eyes and avoid leaning
over the battery whenever possible.
-A discharged battery can freeze at tempera
tures just below 32 °F (0 °C). Before con
necting a jumper cable, you must thaw the
250
frozen battery completely, otherwise it could explode.
- Do not allow battery acid to contact eyes or
skin. Flush any contacted area with water immediately.
- Improper use of a booster battery to start a
vehicle may cause an explosion.
- Vehicle batteries generate explosive gases.
Keep sparks, flame and lighted cigarettes
away from batteries.
- Do not try to jump start any vehicle with a
low acid level in the battery.
- The voltage of the booster battery must also
have a 12-Volt rating. The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batteries of different voltage or substantial
ly different "Ah" rating may cause an explo
sion and personal injury.
- Never charge a frozen battery. Gas trapped in the ice may cause an explosion.
- Never charge or use a battery that has been
frozen . The battery
case may have be weak
ened .
- Use of batteries of different voltage or sub
stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
~page 203.
CD Note
-Applying a higher voltage booster battery
will cause expensive damage to sensitive
electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between
the vehicles as otherwise current could al
ready start to flow as soon as the positive
(+) terminals are connected.
@ Tips
The discharged battery must be properly con-
nected to the vehicle's electrical system. .,..

(D Note
- Be aware of the fo llowing po ints befo re lift
ing the vehicle:
- The vehicle should never be lifted or
jacked up from underneath the engine oil pan, the transmission housing, the front
or rear axle or the body side members .
This could lead to serious damage .
- To avoid damage to the underbody or
chassis frame, a rubber pad must be in
serted between the floor jack and the lift
points.
- Before driving over a workshop hoist,
check that the vehicle weight does not
exceed the permissible lifting capacity of
the hoist.
- Before driving over a workshop hoist , en
sure that there is sufficient clearance be
tween the hoist and low parts of the ve
h icle.
