Using Cruise Control on Hills
How well your cruise control works on hills depends
upon your speed, load, and the steepness of the
hills. When going up steep hills, you might want
to step on the accelerator pedal to maintain the
vehicle speed. When going downhill, you might
have to brake or shift to a lower gear to keep the
vehicle speed down. Of course, applying the brake
turns off the cruise control. Many drivers nd this
to be too much trouble and do not use cruise control
on steep hills.
Ending Cruise Control
To turn off the cruise control, do one of the following:
Step lightly on the brake pedal.
Move the cruise control switch to off.
Lightly tap or press the clutch, if you have
a manual transmission.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
the cruise control set speed memory is erased.
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.
162

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 turn on the parking lamps, together
with the following:
Sidemarker Lamps
Taillamps
License Plate Lamps
Instrument Panel Lights
2(Headlamps):Turn the knob to this position
to turn on the headlamps, together with the
previously listed lamps and lights.
You can switch your headlamps from low to high
beam by pushing the turn signal/multifunction
lever toward the instrument panel.
Headlamps on Reminder
A headlamp reminder chime will sound if the
following conditions are met:
The driver door is open.
Parking lamps or headlamps are manually
turned on.
The key is either not in the ignition switch, or it
is in the LOCK position of the ignition switch.
The headlamp reminder cannot be turned off if
the conditions listed above are met.
In the automatic mode, the headlamps turn off
once the ignition is in ACC.
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.
164

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 162.
Vehicles rst sold in Canada cannot turn
off DRL unless certain conditions are met.
SeeExterior Lamps on page 162.
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.
165

If you start your vehicle in a dark garage, the
automatic headlamp system will come on
immediately. Once you leave the garage, it will
take about one minute for the automatic headlamp
system to change to DRL if it is light outside.
During that delay, the instrument panel cluster
may not be as bright as usual. Make sure
the instrument panel brightness control is in
the full bright position. SeeInstrument Panel
Brightness on page 167.
Off-Road Lamps
The off-road lamps, if the vehicle has them,
provide auxiliary lighting when the vehicle is
used off road. These lamps are not intended to
be used in place of existing vehicle lighting.
The lamps are not to be used on any public street
or highway and are to be covered when not in
use. Check your state and local laws before
installing or using any auxiliary lighting. In some
states it may be necessary to remove the roof
lamps when operating the vehicle on the highway.The switches for the off-road lamps are located in
the center of the instrument panel below the climate
controls. One switch is used for the front lower-grille
mounted off-road lamps, if the vehicle has them,
and the other switch is used for the roof-mounted
off-road lamps, if the vehicle has them.
To use the lamps, remove the covers from the
lamps and press the switch to turn them on or
off. An indicator light on the switch will turn
on when the lamps are on.
Notice:Turning on the off-road lamps before
removing the lamp covers could damage the
off-road lamps and the covers. Always remove
the covers before turning on the off-road lamps.
The off-road lamps remain on even after the ignition
is turned off. The off-road lamp switch must be
pressed to turn them off.

Dome Lamp Override
E(Dome Lamp Override):You can use the
dome override button, located below the exterior
lamps control, to set the dome and footwell
lamps to come on automatically when a door is
opened, or to remain off. To turn the lamps
off, press the button into the in position. With the
button in this position, the dome lamps will
remain off when the doors are open. To return
the lamps to automatic operation, press the
button again and return it to the out position.
With the button in this position, the dome lamps
will come on when you open a door.
Exit Lighting
With exit lighting, the interior lamps will come
on when you remove the key from the ignition.
The lamps will not come on if the dome override
button is pressed in.
Reading Lamps
Your vehicle has reading lamps. Press the button
located next to the lamp to turn them on or off.
These lamps will not come on with the dome lamps.
Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It then adjusts the voltage for best
performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage, you may
see the voltage move up or down. This is normal.
If there is a problem, an alert will be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to
produce all the power that is needed for very
high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.

Battery Run-Down Protection
This feature shuts off the dome lamp if it is left
on for more than 20 minutes when the ignition
is in LOCK. This will help prevent your battery
from running down.
Accessory Power Outlet(s)
Your vehicle has accessory power outlets.
With accessory power outlets you can plug in
auxiliary electrical equipment such as a cellular
telephone or CB radio.
Your vehicle has two accessory power outlets
located on the lower part of the instrument panel
below the climate control system and there
may be one located in the rear cargo area.
A small cap must be pulled down to access an
accessory power outlet. When not using an outlet,
be sure to cover it with the protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always
unplug electrical equipment when not in use
and do not plug in equipment that exceeds the
maximum amperage rating of 20 amperes.Certain electrical accessories may not be
compatible with the accessory power outlet and
could result in blown vehicle or adapter fuses.
If you experience a problem, see your dealer for
additional information on accessory power outlets.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should.
The repairs would not be covered by your
warranty. Do not use equipment exceeding
maximum amperage rating of 20 amperes.
Check with your dealer before adding electrical
equipment.
When adding electrical equipment, be sure to
follow the proper installation instructions included
with the equipment.
Notice:Improper use of the power outlet
can cause damage not covered by your
warranty. Do not hang any type of accessory
or accessory bracket from the plug because
the power outlets are designed for accessory
power plugs only.
