performance braking system. This
brake system is designed for
superior fade resistance and
consistent operation using high
performance brake pads. Brake
squeal is normal and does not affect
system performance.
Tire Chatter/Hop
When driving at slow speeds and in
very tight turns, the vehicle may
have tire chatter/hop. This condition
is normal and the vehicle does not
require service.
Road Imperfections/Crown Effects
The vehicle's precise steering and
handling make it very responsive to
road surface feedback. A slight pull
may be felt in the steering
depending on the crown of the road
and/or other road surface variations
such as troughs or ruts. This is
normal and the vehicle does not
require service.Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays a CHANGE ENGINE
OIL SOON DIC message when it is
necessary to change the engine oil
and filter. The oil life system should
be reset to 100% only following an
oil change.
Resetting the Oil Life System
1. Scroll through the DIC InfoPages menu until the
REMAINING OIL LIFE
percentage is displayed. See
Driver Information Center (DIC)
on page 5-26.
2. Press and hold the SEL button on the DIC while the Oil Life
display is active. The oil life will
change to 100%.
See Engine Oil Life System on
page 10-18.
Car Wash Guidelines
{Caution
Some automatic car washes can
cause damage to the vehicle,
wheels, or convertible top,
if equipped. Automatic car
washes are not recommended,
due to lack of clearance for the
undercarriage and/or wide rear
tires and wheels. See "Washing
the Vehicle" under Exterior Care
on page 10-82

The immobilization system is
disarmed when the ignition is placed
in ACC/ACCESSORY or ON/RUN/
START and a valid transmitter is
found in the vehicle.
You do not have to manually arm or
disarm the system.
The system has one or more RKE
transmitters that are matched to an
immobilizer control unit in the
vehicle. Only a correctly matched
RKE transmitter starts the vehicle.
The vehicle may not start if the RKE
transmitter is damaged.
If the engine does not start and the
security light comes on, there may
be a problem with the immobilizer
system. Press the ENGINE START/
STOP button again.
If the vehicle does not start and the
RKE transmitter appears to be
undamaged, try another RKE
transmitter. Or, place the transmitter
in the transmitter pocket. See“NO
REMOTE DETECTED” underKey
and Lock Messages on page 5-38. Check the fuse. See
Fuses on
page 10-39. If the engine still does
not start with the other transmitter,
the vehicle needs service. If the
engine does start, the first
transmitter may be faulty. See your
dealer or have a new RKE
transmitter programmed to the
vehicle.
The immobilizer system can learn
new or replacement RKE
transmitters. Up to eight RKE
transmitters can be programmed for
the vehicle. To program additional
transmitters, see “Programming
Transmitters to the Vehicle” under
Remote Keyless Entry (RKE)
System Operation on page 2-3.
Do not leave the key or device that
disarms or deactivates the
theft-deterrent system in the vehicle.Exterior Mirrors
Convex Mirrors
{Warning
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.

Conditions such as severe cold or
ice may cause the window to

due to loss of power. Before
returning to the dealer for service,
perform the window indexing reset
procedure.
Window Indexing and
Express-Up Reset
Window indexing may be required if
the vehicle battery has been
recharged or disconnected, or is not
working. Express-up and the
