{CAUTION:
If you have a manual transmission removing
the key from the ignition switch will lock the
steering column and result in a loss of ability
to steer the vehicle. This could cause a
collision. If you need to turn the engine off
while the vehicle is moving, turn the key to
ACC/ACCESSORY.
ACC (ACC/ACCESSORY):This position operates
some of your electrical accessories. It unlocks the
steering wheel and ignition.
R(ON/RUN):This is the position the switch returns
to after you start your engine and release the switch.
The switch stays in the ON/RUN position when the
engine is running. But even when the ignition is
not running, you can use ON/RUN to operate your
electrical accessories and to display some warning
and indicator lights.The battery could be drained if you leave the key in
the ACC/ACCESSORY or ON/RUN position with
the engine off. You may not be able to start your
vehicle if the battery is allowed to drain for an extended
period of time.
/(START):This position starts the engine. When
the engine starts, release the key. The ignition switch
will return to ON/RUN for normal driving.
A warning tone will sound if you open the driver’s door
while in LOCK/OFF or ACC/ACCESSORY, when
the key has not been removed from the ignition.
Key In the Ignition
Never leave your vehicle with the keys inside, as it is
an easy target for joy riders or thieves. If you leave the
key in the ignition and park your vehicle, a chime will
sound, when you open the driver’s door. Always
remember to remove your key from the ignition and take
it with you. This will lock your ignition and transmission.
Also, always remember to lock the doors.
The battery could be drained if you leave the key in the
ignition while your vehicle is parked. You may not be
able to start your vehicle after it has been parked for
an extended period of time.

This position must be selected in order for the Wiper
Activated Headlamps to be activated. SeeWiper
Activated Headlamps on page 3-13.
P(Off/On):When operating in AUTO, a momentary
turn of the switch to Off/On will turn the Automatic
Headlamp System off or back on. For vehicles rst sold
in Canada, the transmission must be in the PARK (P)
position, before the Automatic Headlamp System can be
turned off.
Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers are turned on. For this
feature to work, automatic lighting must be enabled.
SeeHeadlamps on page 3-12for additional information.
When the ignition is turned off, the wiper-activated
headlamps will immediately turn off. They will also turn
off 15 seconds after the windshield wiper control is
turned off.
Headlamps on Reminder
If the driver’s door is opened with the ignition off and
the lamps on, a warning chime will sound. This lets you
know that the headlamps are still on.
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 vehicle has a light sensor on
top of the instrument panel. Make sure it is not covered,
or the head lamps will be on when not needed.
The DRL system will make the headlamps come on
when the following conditions are met:
The ignition is on.
The exterior lamps control is in AUTO or the
parking lamps only position.
The light sensor detects daytime light.
The parking brake is released.
When the DRL system is on, the taillamps, sidemarker
lamps, parking lamps, and instrument panel lights
will not be illuminated unless you have turned the
exterior lamps control to the parking lamp position.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Warning Lights, Gages, and
Indicators
This section describes the warning lights and gages on
your vehicle.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. Some
warning lights come on briey when you start the engine
just to let you know they are working. If you are
familiar with this section, you should not be alarmed
when this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there is a problem with your vehicle.
When one of the warning lights comes on and stays on
as you are driving, or when one of the gages shows
there may be a problem, check the section that tells
you what to do about it. Follow this manual’s advice.
Waiting to do repairs can be costly and even dangerous.

DIC Warnings and Messages
These messages appear if there is a problem detected
in one of your vehicle’s systems.
A message clears when the vehicle’s condition is no
longer present. To acknowledge a message and clear it
from the display, press and hold any of the DIC buttons.
If the condition is still present, the warning message
comes back on the next time the vehicle is turned
off and back on. With most messages, a warning chime
sounds when the message displays. Your vehicle
may have other warning messages.
AUTO (Automatic) LIGHTS OFF
This message displays if the automatic headlamp
system is disabled with the headlamp switch.
AUTO (Automatic) LIGHTS ON
This message displays if the automatic headlamp
system is enabled with the headlamp switch.
BRAKE FLUID
This message displays, while the ignition is on, when
the brake uid level is low. The brake system warning
light on the instrument panel cluster also comes on.
SeeBrake System Warning Light on page 3-31for more
information. Have the brake system serviced by your
dealer/retailer as soon as possible.
CHANGE OIL SOON
This message displays when the life of the engine oil
has expired and it should be changed.
When this message is acknowledged and cleared from
the display, the engine oil life system must still be
reset separately. SeeEngine Oil Life System on
page 5-16andScheduled Maintenance on page 6-4
for more information.
CHECK GAS CAP
This message displays if the fuel cap has not been fully
tightened. Recheck the fuel cap to make sure that it
is on properly. A few driving trips with the cap properly
installed should turn the message off.
CHECK TIRE PRESS (Pressure)
This message displays when the pressure in one or
more of the vehicle’s tires needs to be checked. If a tire
pressure message appears on the DIC, stop as soon
as you can. Have the tire pressures checked and set to
those shown on the Tire Loading Information label.
SeeTires on page 5-49,Loading Your Vehicle on
page 4-27, andInflation - Tire Pressure on page 5-56.
The DIC also shows the tire pressure values. See
DIC Operation and Displays on page 3-40. If the tire
pressure is low, the low tire pressure warning light
comes on. SeeTire Pressure Light on page 3-34.
3-43

Traction Control Operation
Traction control limits wheel spin by reducing engine
power to the wheels (engine speed management)
and by applying brakes to each individual wheel
(brake-traction control) as necessary.
The traction control system is enabled automatically
when you start your vehicle, and it will activate and ash
the ESC/TCS light and display the LOW TRACTION
message if it senses that any of the wheels are spinning
or beginning to lose traction while driving. For more
information on the LOW TRACTION message,
seeDriver Information Center (DIC) on page 3-40.
Notice:If you allow the wheel(s) of one axle to spin
excessively while the ESC/TCS, ABS and Brake
warning lights and the SERVICE ESC and/or
SERVICE TRACTION messages are displayed, you
could damage the differential. The repairs would not
be covered by your warranty. Reduce engine
power and do not spin the wheel(s) excessively
while these lights and this message are displayed.Notice:When traction control is turned off, or
Competitive Driving Mode is active, it is possible to
lose traction. If you attempt to shift with the front
wheels spinning with a loss of traction, it is possible
to cause damage to the transmission. Do not
attempt to shift when the front wheels do not have
traction. Damage caused by misuse of the vehicle
is not covered. See your warranty book for
additional information.
The traction control system may activate on dry or
rough roads or under conditions such as heavy
acceleration while turning or abrupt upshifts/downshifts
of the transmission. When this happens, you may notice
a reduction in acceleration, or may hear a noise or
vibration. This is normal.
If your vehicle is in cruise control while the system
activates, the ESC/TCS light ashes and the cruise
control automatically disengages. When road conditions
allow you to use cruise control again, you may
re-engage the cruise control. SeeCruise Control on
page 3-10.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
