Tilt Wheel
A tilt wheel allows the steering wheel to be adjusted
before driving. It can be raised to allow more room for
the driver to enter and exit the vehicle.
The tilt lever is located on the left side of the steering
column, under the turn signal lever.
To tilt, hold the steering wheel and pull the tilt lever
toward you. Move the wheel to a comfortable level, then
release the tilt lever to lock the wheel in place.
Do not adjust the steering wheel while driving.

It works even if the headlamps are in the automatic
position.
To use it, pull the turn signal lever toward you, then
release it.
If your headlamps are in the automatic position or on
low beam, your high-beam headlamps will turn on. They
will stay on as long as you hold the lever toward you.

will come on. Release the lever to return to normal
operation.

Exterior Lamps
The control on the driver’s side of your instrument panel
operates the exterior lamps.
O(Exterior Lamps):Turn the knob, located to the
right of this symbol, to choose one of the four exterior
lamp positions.
O(Off):Turn the knob to this position to turn off all
exterior lamps, including the Daytime Running
Lamps (DRL). This is a momentary control that springs
back to AUTO when released. Vehicles rst sold in

unless the following conditions are met:
The vehicle has an automatic transmission.
The gear position is in PARK (P).
The headlamp switch is turned to the Off position.
AUTO (Automatic):Turn the knob to this position
to automatically turn on the headlamps at normal
brightness, together with the following:
Sidemarker Lamps

AUTO position.

and release the control. It will return back to
the AUTO position by itself.
Turn the headlamp control from the parking lamp or

and release the control. It will return back to
the AUTO position by itself.
Turn the headlamp control from AUTO to the
parking lamp or headlamp position.
SeeAutomatic Headlamp System on page 3-17for
more information.
Vehicles rst sold in Canada with an automatic
transmission cannot turn off automatic headlamps
unless the gear position is in PARK (P) and the
headlamp switch is turned to the Off position. Vehicles
rst sold in Canada with a manual transmission can
turn off the automatic headlamps with the headlamp
control; however, the parking lamps will remain on.
;(Parking Lamps):Turn the knob to this position to

the LOCK position of the ignition switch.
The headlamp reminder cannot be turned off if the
conditions listed above are met.

ignition is in ACC.
3-16

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
rst sold in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in PARK (P) if you have an
automatic transmission.
The light sensor determines it is daytime.
When the DRL are on, no other lamps are on. The
instrument panel will not be lit up either. For vehicles rst
sold in Canada, if parking lamps are manually turned
on, DRL will stay on.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
To turn off the DRL, seeExterior Lamps on page 3-15.Vehicles rst sold in Canada cannot turn off DRL unless
certain conditions are met. SeeExterior Lamps on
page 3-15.
Automatic Headlamp System
When it is dark enough outside, the automatic headlamp
system will turn on after the transmission has been
shifted from PARK (P) to DRIVE (D). The headlamps,
taillamps, sidemarker, parking lamps, roof marker lamps,
and the instrument panel lights will turn on at normal
brightness. The radio lights will become more dim when
the headlights are off compared to when the headlights
are on.
Your vehicle has a light sensor located on the top of the
instrument panel. Be sure it is not covered, or the
system will be on whenever the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp system so
that driving under bridges or bright overhead street lights
does not affect the system. The DRL and automatic
headlamp system will only be affected when the
light sensor detects a change in lighting lasting longer
than the delay.
