5. Run the engine until it reaches normal
operating temperature. While the
engine is warming up, complete the
following: Reset the clock. Reset the
power windows bounce-back feature.
See Windows and Mirrors (page 98).
Reset the radio station presets. See
Audio System (page 445).
6. Allow the engine to idle for at least one
minute.
7. Drive the vehicle at least 10 mi (16 km)
to completely relearn the idle trim and
fuel trim strategy.
Note: If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel
trim strategy.
Note: For flexible fuel vehicles, if you are
operating on E85, you may experience poor
starts or an inability to start the engine and
driveability problems until the fuel trim and
ethanol content have been relearned.
Make sure that you dispose of old batteries
in an environmentally friendly way. Seek
advice from your local authority about
recycling old batteries.
If storing your vehicle for more than 30
days without recharging the battery, we
recommend that you disconnect the
battery cables to maintain battery charge
for quick starting.
Battery Management System
(If
Equipped)
The battery management system monitors
battery conditions and takes actions to
extend battery life. If excessive battery
drain is detected, the system temporarily
disables some electrical systems to
protect the battery. Systems included are:
•
Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.
A message may appear in the information
displays to alert you that battery
protection actions are active. These
messages are only for notification that an
action is taking place, and not intended to
indicate an electrical problem or that the
battery requires replacement.
After battery replacement, or in some
cases after charging the battery with an
external charger, the battery management
system requires eight hours of vehicle sleep
time to relearn the battery state of charge.
During this time your vehicle must remain
fully locked with the ignition switched off.
Note: Prior to relearning the battery state
of charge, the battery management system
may temporarily disable some electrical
systems.
Electrical Accessory Installation
To make sure the battery management
system works correctly, do not connect an
electrical device ground connection
directly to the battery negative post. This
can cause inaccurate measurements of
the battery condition and potential
incorrect system operation.
Note: If you add electrical accessories or
components to the vehicle, it may adversely
affect battery performance and durability.
This may also affect the performance of
other electrical systems in the vehicle.

CHECKING THE WIPER
BLADES
Run the tip of your fingers over the edge of
the blade to check for roughness.
Clean the wiper blades with washer fluid
or water applied with a soft sponge or
cloth.
CHANGING THE WIPER
BLADES
You can manually move the wiper arms
when the ignition is off. This allows for ease
of blade replacement and cleaning under
the blades.
1. Pull the wiper blade and arm away
from the glass. 2. Release the wiper blade lock (A) and
separate the wiper blade from the
wiper arm.
3. Install in the reverse order.
Note: Make sure that the wiper blade locks
into place. Lower the wiper arm and blade
back on the windshield. The wiper arms will
automatically return to their normal position
when you turn the ignition on.
• Replace wiper blades at least once per
year for optimum performance.
• You can improve poor wiper quality by
cleaning the wiper blades and the
windshield.
ADJUSTING THE HEADLAMPS
Vertical Aim Adjustment
The headlamps on your vehicle are
properly aimed at the assembly plant. If
your vehicle has been in an accident, the
alignment of your headlamps should be
checked by your authorized dealer.
