Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness
and reduces brake pad life. In
addition, f uel economy can be
reduced. It also keeps your brake
lights on all the time, conf using
drivers behind you.
Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. The anti-lock
brake system (ABS) helps you retain
steering control when braking very
hard.
Always use the parking brake when
you park your vehicle. Make sure
the parking brake is set f irmly, or
your vehicle may roll if it is parked
on an incline.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear.
Make sure the convertible top and
the windows are closed.
Make sure the removable hardtop
is properly installed and the
windows are closed.
Make sure the parking brake is
f ully released bef ore driving away.
Driving with the parking brake
partially set can overheat or
damage the rear brakes.
If the vehicle is f acing downhill,
turn the front wheels toward the
curb, and put the transmission in
reverse gear.
If the vehicle is f acing uphill, turn
the front wheels away from the
curb, and put the transmission in
f irst gear.
Never park over dry leaves, tall
grass, or other f lammable materials. The hot three way
catalytic converter could cause
these materials to catch on fire.
Lock the doors.
Place any packages, valuables, etc.,
in the trunk or take them with you.
Turn of f the lights.

beam headlight bulb fails, take the
vehicle to your dealer to have it
replaced.Halogen bulbs are used f or the high
