WARNING
Working on the batteries or the electrical system in your vehicle can cause serious acid
burns, fires, explosions, or electrical shocks. Always read and heed the following WARNINGS
and safety precautions before working on the batteries or the electrical system.
x Before working on the electrical system, always switch off the ignition and all electrical
consumers and disconnect the negative (-) cable from the standard 12 Volt battery.
x When you change a light bulb, always switch off the light first.
x Always keep children away from battery acid and vehicle batteries in general.
x Always wear eye protection. Never let battery acid or lead particles come into contact with
your eyes, skin, or clothing.
x Sulfuric battery acid is very corrosive. It can burn unprotected skin and cause blindness.
Always wear protective gloves and eye protection. To reduce your risk of injury, never tilt the
batteries, as this could spill acid through the vents and burn you.
x If you get battery acid in your eyes or on your skin, immediately rinse with cold water for
several minutes and then get immediate medical attention. If you swallow any battery acid,
get medical attention immediately.
x When disconnecting the batteries from the vehicle electrical system, always disconnect
the negative cable (-) first and then the positive cable (+).
x Always switch off all electrical consumers before reconnecting 12 Volt batteries.
Reconnect the plus cable (+) first and then the negative cable (-). Never reverse the polarity of
the connections. This could cause a fire.
x A highly explosive mixture of gases is given off when the battery is being charged.
x Do not smoke and avoid fires, sparks, and open flames when working. Never create
sparks or electrostatic charges when handling cables and electrical equipment. Never short
circuit the battery terminals. High-energy sparks can cause serious personal injury.
x Never use or attempt to charge a damaged or frozen battery, or a battery that was frozen
but has thawed. Charging a frozen or thawed battery could cause explosions and chemical
burns! Replace damaged or frozen vehicle batteries immediately. A dead battery can freeze at
temperatures around +32 °F (0 °C).
x If the battery has a vent line or tube, make sure that it is properly connected to the battery.

WARNING
California Proposition 65 Warning
x Battery posts, terminals, and related accessories contain lead and lead components,
chemicals known to the State of California to cause cancer and reproductive harm. Wash
your hands after handling.

NOTICE
x Do not expose the vehicle battery to direct sunlight for an extended period of time as
ultraviolet rays may damage the battery housing.
x If the vehicle is left standing in the cold for a long time, protect the vehicle battery from
freezing. A battery will be permanently damaged by freezing.
Emergency starting and starting the engine with a very weak vehicle battery or after the vehicle
battery has been replaced may change or delete system settings (including time, date, personal
convenience settings, and programming). Check the settings and correct as necessary once the
vehicle battery has built up a sufficient charge.
Warning light

WARNING
After the vehicle has been washed, the wet brakes or, in winter, brake discs or pads coated
with ice, react slower and need longer stopping distances.
x Always dry the brakes and clean off any ice coatings with a few careful applications of the
brake. Make sure not to endanger other motorists or cyclists or disobey legal requirements.

NOTICE
x Water temperature should not be more than +140 °F (+60 °C).
x To help prevent damage to the paint, do not wash the vehicle in direct sunlight.
x Do not clean icy or snow-covered windows with a power washer.
x When washing or rinsing the vehicle in cold weather, do not let water get into the lock
cylinders or point the hose at gaps around the doors, hood, or luggage compartment lid. The
water could freeze on the locks and seals and make it difficult to open the vehicle!
Undercoating

WARNING
Improper use of a spare wheel or a compact spare wheel can cause loss of vehicle control, a
crash or other accident, and serious personal injury.
x Never use a spare wheel or compact spare wheel if it is damaged or worn down to the
wear indicators.
x In some vehicles, the spare wheel or compact spare wheel is smaller than the original tire.
A smaller compact spare wheel is identified with a sticker and the words “50 mph” or
“80 km/h”. This is the maximum permissible speed when driving with this tire.
x Never drive faster than 50 mph (80 km/h) with a compact spare wheel. Avoid full-throttle
acceleration, heavy braking, and fast cornering!
x Never drive more than 125 miles (200 km) if a compact spare wheel is installed on the front
axle (drive axle).
x Replace the compact spare with a normal wheel and tire as soon as possible. Compact
spare tires are designed for brief use only.
x Regularly check the U.S. DOT Tire Identification Number (TIN) to determine the age of the
compact spare wheel . Tires age even if they are not being used and can fail suddenly,
especially at higher speeds.
x Tires that are more than 6 years old can only be used in an emergency and then with
special care and at lower speeds.
x The compact spare wheel must always be secured with the wheel bolts provided by the
factory.
x Never drive using more than one compact spare wheel.
x After installing the compact spare wheel, the tire pressure must be checked as soon as
possible .
x Snow chains cannot be used on the compact spare wheel. If you must use snow chains
and have a compact spare wheel mounted, move the compact spare wheel to the rear axle if a
front tire has to be replaced. The tire taken off the rear axle can then be used to replace the
flat front tire. Be sure you do not change the tire's direction of rotation. Install the snow
chains on the full-sized road tire.

NOTICE
When the spare wheel or compact spare is being used, the TPMS indicator light can come on
after a couple of minutes .
If possible, attach the spare wheel, compact spare wheel, or wheel you took off the vehicle
securely in the luggage compartment.

Speed rating (letter code)
A standardized letter code indicating the maximum speed at which a tire is designed to be driven for
extended periods of time. The ratings range from 93 mph or 150 km/h (“P”) to 186 mph or (300 km/h)
“Y”.
The speed rating letter code, where applicable, is molded on the tire sidewall . You may not find this
information on all tires because it is not required by law.
Tire Pressure Monitoring System
A system that detects when at least one of a vehicle's tires is underinflated and illuminates a low tire-
pressure warning light.
Tread
The portion of a tire that normally touches the road.
Tread rib
A tread section running circumferentially around a tire.
Tread separation
Tire failure caused by the tread pulling away from the tire carcass.
Tread wear indicators (TWI)
Raised areas within the main tread grooves that show, visually, when tires are worn and near the end
of their useful life , Tread depth and tread wear indicators.
Uniform Tire Quality Grading (UTQG)
A tire information system developed by the U.S. National Highway Traffic Safety Administration
(NHTSA) that is designed to help buyers compare tires. UTQG is not a safety rating, nor is it a
guarantee that a tire will last for a certain number of miles or perform a certain way. It gives tire buyers
more information to compare with factors such as price, brand loyalty and dealer recommendations.
Under UTQG, tires are graded by the tire manufacturers in 3 areas: tread wear, traction and
temperature resistance. UTQG information is molded into the tire sidewalls.
U.S. DOT Tire Identification Number (TIN)
A tire's serial number. It begins with the letters “DOT” (“Department of Transportation”) and indicates
that the tire meets all federal standards. The next 2 numbers or letters indicate the plant where the tire
was manufactured. The last 4 numbers represent the week and year of manufacture.
For example, the numbers 1709 mean that the tire was produced in the 17th week of 2009. Any other
numbers are marketing codes used by the tire manufacturer. This information is used to help identify
affected consumers if a tire defect requires a recall.
Vehicle capacity weight
The total rated cargo, luggage and passenger load. Passenger load is 150 lbs (68 kilograms) times the
vehicle's total seating capacity (as listed on the label inside the driver door).
Vehicle maximum load on the tire
The load on an individual tire that is determined by taking each axle's share of the maximum loaded
vehicle weight (GAWR) and dividing by 2.
Vehicle normal load on the tire
The load on an individual tire that is determined by taking each axle's share of the curb weight,
accessory weight, and normal occupant weight (distributed according to the table below) and dividing
by 2.
