ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should
be checked at the mileage intervals in the scheduled
maintenance guide. The coolant concentration
should be maintained at 50/50 coolant and water,
which equates to a freeze point of -36°C (-34°F).
Coolant concentration testing is possible with a
hydrometer or antifreeze tester (such as the
Rotunda Battery and Antifreeze Tester, 014–R1060).
The level of coolant should be maintained at the
“cold full”of“cold fill range”level in the coolant
reservoir. If the level falls below, add coolant per the
instructions in theAdding Engine Coolantsection.
Your vehicle was factory-filled with a 50/50 engine
coolant and water concentration. If the
concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not
work properly.A50–50 mixture of coolant and
water provides the following:
•freeze protection down to -36°C (-34°F)
•boiling protection up to 129°C (265°F)
•protection against rust and other forms of
corrosion
•enables calibrated gages to function properly

injury. If fuel is swallowed, call a physician
immediately, even if no symptoms are immediately
apparent. The toxic effects of fuel may not be
visible for hours.
•Avoid inhaling fuel vapors. Inhaling too much fuel
vapor of any kind can lead to eye and respiratory
tract irritation. In severe cases, excessive or
prolonged breathing of fuel vapor can cause
serious illness and permanent injury.
•Avoid getting fuel liquid in your eyes. If fuel is
splashed in the eyes, remove contact lenses (if
worn), flush with water for 15 minutes and seek
medical attention. Failure to seek proper medical
attention could lead to permanent injury.
•Fuels can also be harmful if absorbed through the
skin. If fuel is splashed on the skin and/or
clothing, promptly remove contaminated clothing
and wash skin thoroughly with soap and water.
Repeated or prolonged skin contact with fuel
liquid or vapor causes skin irritation.
•Be particularly careful if you are taking
“Antabuse”or other forms of disulfiram for the
treatment of alcoholism. Breathing gasoline
vapors, or skin contact could cause an adverse
reaction. In sensitive individuals, serious personal
injury or sickness may result. If fuel is splashed
on the skin, promptly wash skin thoroughly with
soap and water. Consult a physician immediately
if you experience an adverse reaction.
When refueling always shut the engine off
and never allow sparks or open flames near
the filler neck. Never smoke while refueling. Fuel
vapor is extremely hazardous under certain
conditions. Care should be taken to avoid inhaling
excess fumes.
The flow of fuel through a fuel pump nozzle
can produce static electricity, which can
cause a fire if fuel is pumped into an ungrounded
fuel container.

•Adding certain accessories to your vehicle (for
example bug deflectors, rollbars/light bars,
running boards, ski/luggage racks) may reduce
fuel economy.
•Using fuel blended with alcohol may lower fuel
economy.
•Fuel economy may decrease with lower
temperatures during the first 12–16 km
(8–10 miles) of driving.
•Driving on flat terrain offers improved fuel
economy as compared to driving on hilly terrain.
•Transmissions give their best fuel economy when
operated in the top cruise gear and with steady
pressure on the gas pedal.
•Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window
sticker. Contact your dealer if the window sticker is
not supplied with your vehicle. The EPA window
sticker should be your guide for the fuel economy
comparisons with other vehicles.
It is important to note the box in the lower left
corner of the window sticker. These numbers
represent the Range of L/100 km (MPG) expected
on the vehicle under optimum conditions. Your fuel
economy may vary depending upon the method of
operation and conditions.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission
control components and a catalytic converter which
will enable your vehicle to comply with applicable
exhaust emission standards. To make sure that the
catalytic converter and other emission control
components continue to work properly:
•Use only the specified fuel listed.
•Avoid running out of fuel.
•Do not turn off the ignition while your vehicle is
moving, especially at high speeds.

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 (1 1/2) 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 AA A B C
The traction grades, from highest to lowest are AA,
A, B, and C. The 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.
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 A B C
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 laboratory test wheel. Sustained
high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The
grade C corresponds to a level of performance which
all passenger car tires must meet under the Federal
Motor Vehicle Safety Standard No. 109. Grades B
and A represent higher levels of performance on the
laboratory test wheel than the minimum required by
law.

Tire inflation pressure
Use a tire gauge to check the tire inflation pressure,
including the spare, at least monthly and before long
trips. You are strongly urged to buy a reliable tire
pressure gauge, as automatic service station gauges
may be inaccurate.
Use the recommended cold inflation pressure for
optimum tire performance and wear. Under-inflation
or over-inflation may cause uneven treadwear
patterns.
Under-inflation is the most common cause of
tire failures and may result in severe tire
cracking, tread separation orblowout, with
unexpected loss of vehicle control and increased
risk of injury. Under-inflation increases sidewall
flexing and rolling resistance, resulting in heat
buildup and internal damage to the tire. It also
may result in unnecessary tire stress, irregular
wear, loss of vehicle control and accidents. A tire
can lose up to half of its air pressure and not
appear to be flat!
When weather temperature changes occur, tire
inflation pressures also change. A 10 degree
temperature change causes a corresponding drop of
7 kPa (1 psi) in inflation pressure. Check your tire
pressures frequently and adjust them to the proper
pressure which can be found on the tire label or
certification label.
If checking tire pressure when the tire is hot, (i.e.
driven more than 1.6 km [1mile]), never“bleed”or
reduce air pressure. The tires are hot from driving
and it is normal for pressures to increase above
recommended cold pressures. A hot tire at or below
recommended cold inflation pressure could be
significantly under-inflated.
To check the pressure in your tire(s):
1. Make sure the tires are cool, meaning they are not
hot from driving even a mile.
Note:If you have to drive a distance to get air for
your tire(s), check and record the tire pressure first
