TECHNICAL SPECIFICATIONS
VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is found on the left front corner of the
instrument panel, visible through the windshield.
Vehicle Identification Number

NOTE:It is illegal to remove or alter the VIN.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems lose
normal capability, the remaining system will still
function. However, there will be some loss of
overall braking effectiveness. You may notice
increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake System Warning Light.
In the event power assist is lost for any reason
(i.e., repeated brake applications with the engine
off), the brakes will still function. However, the
effort required to brake the vehicle will be much
greater than that required with the power system
operating.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to the
vehicle. Any time a wheel has been removed and
reinstalled on the vehicle, the lug nuts/bolts
should be torqued using a properly calibrated
torque wrench using a six-sided (hex) deep wall
socket.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended lug
nuts/bolts and clean or remove any dirt or oil
before tightening.CAUTION!
If the Brake System Warning Light remains on
with the parking brake released, a brake system
malfunction is indicated. Have the brake system
serviced by an authorized dealer immediately.

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).
Torque Patterns

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.
FUEL REQUIREMENTS

While operating on gasoline with the required octane
number, 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 a lower than
recommended octane number 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.
3.6L ENGINE
This engine is designed to meet all
emission regulations and provide
optimum fuel economy and performance
when using high quality unleaded regular
gasoline having a posted octane number of 87
as specified by the (R+M)/2 method. The use of
higher octane premium gasoline is not required,
as it will not provide any benefit over regular
gasoline in these engines.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.
