Vehicle Stability Assist
(VSA) System Indicator
This indicator normally comes on for
a few seconds when you turn the
ignition switch to the ON (II)
position.
If it comes on and stays on at any
other time, or it does not come on
when you turn the ignition switch to
the ON (II) position, there is a
problem with the VSA system. You
will also see a ‘‘CHECK VSA
SYSTEM ’’message on the multi-
information display (see page81).
Take your vehicle to a dealer to have
it checked. Without VSA, your
vehicle still has normal driving
ability, but will not have VSA traction
and stability enhancement. For more
information, see page359.
This indicator may also come on if
there is a problem with the trailer
stability assist function (see page
376).
VSA Activation Indicator
This indicator normally comes on for
a few seconds when you turn the
ignition switch to the ON (II)
position. For more information, see
page359.
This indicator has four functions.
1. It comes on as a reminder that you have turned off the vehicle stability
assist (VSA) system.
2. It flashes when VSA is active (see page359).
3. It flashes when trailer stability assist is activating (see page376).
4. It comes on along with the VSA system indicator if there is a
problem with the VSA system. You
will also see a ‘‘CHECK VSA
SYSTEM ’’message and a
‘‘ CHECK TRAILER STABILITY
ASSIST ’’message on the multi-
information display (see page81).
Turn Signal and
Hazard Warning
Indicators
The left or right turn signal indicator
blinks when you signal a lane change
or turn. If an indicator does not blink
or blinks rapidly, it usually means
one of the turn signal bulbs is burned
out (see page404).Replace the bulb
as soon as possible, since other
drivers cannot see that you are
signaling.
When you press the hazard warning
button, both turn signal indicators
and all turn signals on the outside of
the vehicle flash.

Headlight Aiming
The headlights were properly aimed
when your vehicle was new. If you
regularly carry heavy items in the
trunk or pull a trailer, readjustment
may be required. Adjustments
should be done by your dealer or
another qualified technician.
Low Beam Headlight Bulb
Replacement
The low beam headlight bulbs are a
type of high voltage discharge tube.
High voltage can remain in the
circuit even with the light switch off
and the key removed. Because of
this, you should not attempt to
examine or change a low beam
headlight bulb yourself. If a low
beam headlight bulb fails, take the
vehicle to your dealer to have it
replaced.Replacing a High Beam Headlight
Bulb
Your vehicle has halogen headlight
bulbs. When replacing a bulb, handle
it by its base, and protect the glass
from contact with your skin or hard
objects. If you touch the glass, clean
it with denatured alcohol and a clean
cloth.
Halogen headlight bulbs get very hot
when lit. Oil, perspiration, or a scratch
on the glass can cause the bulb to
overheat and shatter.
1. Open the hood.
2. Remove the front bulkhead cover
(see page392).
3. Remove the electrical connectorfrom the bulb by pushing on the
tab and pulling the connector
down.
4. Remove the bulb by turning it about one-quarter turn
counterclockwise.
