Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel bolts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, or brake fluid leaks are
suspected. The cause should be located and corrected
immediately.

Vehicles Equipped With Wheel Covers
1. Mount the road tire on the axle.
2. To ease the installation process for steel wheels withwheel covers, install two wheel bolts on the wheel.
Install the wheel bolts with the threaded end of the bolt
toward the wheel. Lightly tighten the wheel bolts. 3. Align the valve notch in the wheel cover with the valve
stem on the wheel. Install the cover by hand, snapping
the cover over the two wheel bolts. Do not use a
hammer or excessive force to install the cover.
4. Install the remaining wheel bolts with the threaded end of the wheel bolt toward the wheel. Lightly tighten the
wheel bolts.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not fully tighten the wheel bolts until the vehicle has
been lowered. Failure to follow this warning may
result in serious injury.
5. Lower the vehicle to the ground by turning the jack handle counterclockwise.
6. Finish tightening the wheel bolts. Push down on the wrench while holding at the end of the handle for
increased leverage. Tighten the wheel bolts in a star
pattern until each wheel bolt has been tightened twice.
Refer to “Torque Specifications” in “Technical Specifica-
tions” for correct wheel bolt torque.

Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles. Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice. Ensure that the socket is

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.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts fully until the vehicle has been
lowered. Failure to follow this warning may result in
personal injury.
FUEL REQUIREMENTS
2.4L Engine
All available gasoline engines are de-
signed to meet all emissions regulations
and provide excellent fuel economy and
performance when using high quality
unleaded “regular” gasoline having a
octane rating of 87 using the (R+M)/2
method. The use of premium gasoline is
not recommended, as it 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 your 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 consider-
ing service for the vehicle.
