284SERVICING AND MAINTENANCE
(Continued)
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning,
keep the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever
necessary, install ONLY the correct type ther-
mostat. Other designs may result in unsatis -
factory engine coolant (antifreeze)
performance, poor gas mileage, and
increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance,
all brake system components should be
inspected periodically. Refer to the
“Maintenance Plan” in this section for the
proper maintenance intervals.
Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder
immediately if the brake system warning light
indicates system failure.
Check the fluid level in the master cylinder
when performing underhood services.
Clean the top of the master cylinder area before
removing the cap. Add fluid to bring the level up
to the top of the “FULL” mark on the side of the
master cylinder reservoir.
Overfilling of fluid is not recommended because
it may cause leaking in the system.
Add enough fluid to bring the level up to the
requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear.
However, low fluid level may be caused by a
leak and a checkup may be needed.
Use only brake fluid that has been
recommended by the manufacturer, and has
been kept in a tightly closed container to avoid
contamination from foreign matter or moisture.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your foot
resting or riding on the brake pedal can result
in abnormally high brake temperatures,
excessive lining wear, and possible brake
damage. You would not have your full braking
capacity in an emergency.
WARNING!

Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri -
cants” in “Technical Specifications” for
further information. Using the wrong type
of brake fluid can severely damage your
brake system and/or impair its perfor -
mance. The proper type of brake fluid for
your vehicle is also identified on the orig -
inal factory installed hydraulic master
cylinder reservoir.
To avoid contamination from foreign
matter or moisture, use only new brake
fluid or fluid that has been in a tightly
closed container. Keep the master
cylinder reservoir cap secured at all times.
Brake fluid in a open container absorbs
moisture from the air resulting in a lower
boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake failure.
This could result in a collision.

TECHNICAL SPECIFICATIONS309
SRT Model Vehicle

**Use only authorized dealer recommended lug
nuts/bolts and clean or remove any dirt or oil before
tightening.

Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.

Wheel Mounting Surface

Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice. Ensure
that the socket is fully engaged on the lug nut/
bolt (do not insert it halfway). NOTE:
If in doubt about the correct tightness, have
them checked with a torque wrench by an
authorized dealer or service station.
After 25 miles (40 km), check the lug nut/bolt
torque to be sure that all the lug nuts/bolts are
properly seated against the wheel.

Torque Patterns
FUEL REQUIREMENTS
3.6L ENGINE

This engine is designed to meet all
emissions regulations and provide
excellent fuel economy and
performance when using high-quality
unleaded “Regular” gasoline having an octane
rating of 87 as specified by the (R+M)/2 method.
The use of higher octane “Premium” gasoline will
not provide any benefit over “Regular” gasoline in
these engines.

While operating on gasoline with an octane
number of 87, hearing a light knocking sound
from the engine is not a cause for concern.
However, if the engine is heard making a heavy
knocking sound, see a dealer immediately. Use
of gasoline with an octane number lower than
87 can cause engine failure and may void or not
be covered by the New Vehicle Limited
Warranty.
Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand
of gasoline before considering service for the
vehicle.

WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts/bolts fully
until the vehicle has been lowered. Failure to
follow this warning may result in personal
injury.
