The test will turn those lights off and then
illuminate the:
•
Park lights
• Side marker lights
• High beam headlamps
• Stop/Brake lights
After turning these lights off, the system
will resume testing the first set of lights.
The light test will eventually stop on its
own. The operator may interrupt the test by
turning the vehicle off or pressing the
switch a second time while the test is
running. The operator can verify light
functionality by visibly watching the lights
from outside the vehicle or by observing
the instrument cluster for lighting-related
warnings. The ELST will also start the
Systems Check (Systems Check on page
37).

Turn signal/wiper/lights
The turn signal lever is mounted on the left
side of the steering column. The lever
controls several functions: turn signal, high

Tilt/Telescoping Steering Wheel
Depending on your vehicle’s configuration,
you may have either a tilt/telescoping
feature.
• The tilt feature allows forward and
rearward movement of the wheel.
• The telescoping feature allows you
to move the wheel up and down.
WARNING
Make all adjustments to the steering
mechanism while the vehicle is stop-
ped. Adjusting the Tilt Telescoping
Steering Wheel while the vehicle is in
motion could cause loss of control.
You would not be able to steer proper-
ly and could have an accident resulting
in death or personal injury.
