Then, check that the nozzle holes are not
clogged; use a needle to unblock them if
necessary.
Exhaust System
Adequate maintenance of the engine
exhaust system represents the best
protection against leaks of carbon
monoxide into the passenger
compartment.
If an unusual noise from the exhaust or
the presence of smoke in the passenger
compartment is identified, or if the
underbody or rear section of the vehicle
have been damaged, have the entire
exhaust system and adjoining bodywork
areas checked at your authorized dealer
to identify any components which are
broken, damaged, worn or have moved
from their correct fitting position.Open welding or loose connections may
permit exhaust gas to enter the
passenger compartment.
Have the exhaust system checked every
time the vehicle is raised. Replace the
components where necessary (for these
operations, contact an authorized
dealer).
In normal operating conditions, the
catalytic converter does not require
maintenance. To ensure that it operates
correctly, however, and prevent it from
getting damaged, it is extremely
important that the engine operates
perfectly.
To minimize the risk of damaging the
catalytic converter, proceed as follows:
Do not stop the engine or deactivate
the ignition with gear engaged and
vehicle in motion.
Do not attempt to start the engine by
bump starting.
Do not persist in using the vehicle if
idling is very irregular or the operating
conditions are very notably irregular.
Warning!
Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventually
poison you.
A hot exhaust system can start a fire if
you park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system.
Do not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.
Cooling System
Warning!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open the
hood until the radiator has had time to cool.
Never open a cooling system pressure cap
when the radiator or coolant bottle is hot.
Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when the
hood is raised. The fan starts automatically
and may start at any time, whether the
engine is running or not.
When working near the radiator cooling
fan, disconnect the fan motor lead or turn
the ignition to the OFF mode. The fan is
temperature controlled and can start at any
time the ignition is in the ON mode.

Frequency Of Oil Changes
In normal vehicle operating conditions, it
is not necessary to change the
transmission oil.
Caution!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately.
Replacing The Battery
If necessary, replace the battery with
another battery with the same
specifications. It is advised to contact an
authorized dealer for replacement.
Follow the battery manufacturer's
instructions for maintenance.
Note:It will not be possible to open the
trunk with a key or by pressing the button
in the passenger compartment when the
battery is disconnected. So, always
position the manual trunk opening strap
on the trunk lock before disconnecting
the battery. The procedure is described in
the "Storing The Vehicle" section in this
chapter.
RAISING THE VEHICLE
If the vehicle requires lifting, visit an
authorized dealer which is equipped with
shop jacks or jack arms.
The vehicle lifting points are marked on
the side skirts with the

Tire Terminology And Definitions
TermDefinition
B-Pillar The
vehicle B-Pillar is the structural member of the body located behind the front door.
Cold Tire Inflation Pressure Cold tire inflation pressure is defined as the tire pressure after the vehicle has not
been driven for at least three hours, or driven less than 1 mile (1.6 km) after sitting for
a minimum of three hours. Inflation pressure is measured in units of PSI (pounds per
square inch) or kPa (kilopascals).
Maximum Inflation Pressure The maximum inflation pressure is the maximum permissible cold tire inflation
pressure for this tire. The maximum inflation pressure is molded into the sidewall.
Recommended Cold Tire Inflation Pressure Vehicle manufacturer's recommended cold tire inflation pressure as shown on the tire
placard.
Tire Placard A label permanently attached to the vehicle describing the vehicle’s loading capacity,
the original equipment tire sizes and the recommended cold tire inflation pressures.
Tire Loading And Tire Pressure
Note:
The proper cold tire inflation
pressure is listed on the driver’s side
B-Pillar or the rear edge of the driver's
side door.
Check the inflation pressure of each tire,
including the spare tire (if equipped), at
least monthly and inflate to the
recommended pressure for your vehicle.

Tire And Loading Information Placard
This placard tells you important
information about the:
1. Number of people that can be carried
in the vehicle.
2. Total weight your vehicle can carry.
3. Tire size designed for your vehicle.
4. Cold tire inflation pressures for the
front, rear, and spare tires.
Loading
The vehicle maximum load on the tire
must not exceed the load carrying
capacity of the tire on your vehicle. You
will not exceed the tire's load carrying
capacity if you adhere to the loading
conditions, tire size, and cold tire
inflation pressures specified on the Tire
and Loading Information placard in
“Vehicle Loading” in the “Starting And
Operating” section of this manual.Note:
Under a maximum loaded vehicle
condition, gross axle weight ratings
(GAWRs) for the front and rear axles
must not be exceeded. For further
information on GAWRs, vehicle loading,
and trailer towing, refer to “Vehicle
Loading” in the “Starting And Operating”
section of this manual.
To determine the maximum loading
conditions of your vehicle, locate the
statement “The combined weight of
occupants and cargo should never
exceed XXX kg or XXX lbs” on the Tire
and Loading Information placard. The
combined weight of occupants,
cargo/luggage and trailer tongue weight
(if applicable) should never exceed the
weight referenced here.
Steps For Determining Correct Load
Limit—
(1) Locate the statement “The
combined weight of occupants and
cargo should never exceed XXX kg or
XXX lbs.” on your vehicle's placard.
(2) Determine the combined weight
of the driver and passengers that will
be riding in your vehicle.
(3) Subtract the combined weight of
the driver and passengers from
XXX kg or XXX lbs. (4) The resulting figure equals the
available amount of cargo and
luggage load capacity. For example,
if “XXX” amount equals 1400 lbs. and
there will be five 150 lb passengers
in your vehicle, the amount of
available cargo and luggage load
capacity is 650 lbs. (1400-750
(5x150) = 650 lbs.)
(5) Determine the combined weight
of luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo and
luggage load capacity calculated in
Step 4.
(6) If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and
luggage load capacity of your vehicle.

Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential
to the safe and satisfactory operation of
your vehicle. Four primary areas are
affected by improper tire pressure:
Safety and Vehicle Stability
Economy
Tread Wear
Ride Comfort
Safety
Warning!
Improperly inflated tires are dangerous
and can cause collisions.
Underinflation increases tire flexing and
can result in overheating and tire failure.
Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that result in
tire failure.
Overinflated or underinflated tires can
affect vehicle handling and can fail
suddenly, resulting in loss of vehicle control.
Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.
Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
Always drive with each tire inflated to the
recommended cold tire inflation pressure.
Both under-inflation and over-inflation
affect the stability of the vehicle and can
produce a feeling of sluggish response or
over responsiveness in the steering.
Note:
Unequal tire pressures from side to
side may cause erratic and
unpredictable steering response.
Unequal tire pressure from side to
side may cause the vehicle to drift left or
right.
Fuel Economy
Underinflated tires will increase tire
rolling resistance resulting in higher fuel
consumption.
Tread Wear
Improper cold tire inflation pressures can
cause abnormal wear patterns and
reduced tread life, resulting in the need
for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a
comfortable ride. Over-inflation
produces a jarring and uncomfortable
ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is
listed on the driver's side B-Pillar or rear
edge of the driver's side door.
At least once a month:
Check and adjust tire pressure with a
good quality pocket-type pressure gauge.
Do not make a visual judgement when
determining proper inflation. Tires may
look properly inflated even when they are
under-inflated.
Inspect tires for signs of tire wear or
visible damage.
Caution!
After inspecting or adjusting the tire
pressure, always reinstall the valve stem
cap. This will prevent moisture and dirt from
entering the valve stem, which could
damage the valve stem.
Inflation pressures specified on the
placard are always “cold tire inflation
pressure”. Cold tire inflation pressure is
defined as the tire pressure after the
vehicle has not been driven for at least
three hours, or driven less than 1 mile
(1.6 km) after sitting for a minimum of
three hours. The cold tire inflation
pressure must not exceed the maximum
inflation pressure molded into the tire
sidewall.
216
SERVICING AND MAINTENANCE

Check tire pressures more often if
subject to a wide range of outdoor
temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately
1 psi (7 kPa) per 12°F (7°C) of air
temperature change. Keep this in mind
when checking tire pressure inside a
garage, especially in the Winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature =
32°F (0°C) then the cold tire inflation
pressure should be increased by 3 psi
(21 kPa), which equals 1 psi (7 kPa) for
every 12°F (7°C) for this outside
temperature condition.
Tire pressure may increase from 2 to
6 psi (13 to 40 kPa) during operation.
DO NOT reduce this normal pressure
build up or your tire pressure will be too
low.Tire Pressures For High Speed
Operation
The manufacturer advocates driving at
safe speeds and within posted speed
limits. Where speed limits or conditions
are such that the vehicle can be driven at
high speeds, maintaining correct tire
inflation pressure is very important.
Increased tire pressure and reduced
vehicle loading may be required for
high-speed vehicle operation. Refer to
your authorized tire dealer or original
equipment vehicle dealer for
recommended safe operating speeds,
loading and cold tire inflation pressures.
Warning!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to fail.
You could have a serious collision. Do not
drive a vehicle loaded to the maximum
capacity at continuous speeds above
75 mph (120 km/h).
Recommended Cold Tire Inflation
Pressures
For vehicle speeds below 100 mph
(160 km/h), recommended cold tire
inflation pressures are listed on the Tire
And Loading Information Placard located
on driver’s side B-Pillar or the rear edge
of the driver's side door.
When driving at speeds 100 mph
(160 km/h) and above, increased tire
pressures and reduced vehicle loading
are required for high-speed vehicle
operation.
For driving speeds above 100 mph
(160 km/h) recommended cold tire
inflation pressures are listed below
under "High Speed Tire Inflation
Pressure". Vehicle loading condition
must not exceed 688 lbs. (312 kg)
(driver + three passengers + 88 lbs.
(40kg) luggage).
Warning!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to fail.
You could have a serious collision.
