to low beams.
This indicator light turns on in the
instrument panel cluster when the
high beam headlamps are on.
Flash-to-Pass
Pull the turn signal lever toward you,
then release it, to signal that you are
going to pass.
If the headlamps are in the
automatic position or on low beam,
the high-beam headlamps will turn
on. They stay on as long as the
lever is held toward you. The
high-beam indicator on the
instrument panel cluster will come
on. Release the lever to return to
normal operation.
Daytime Running
Lamps (DRL)
Daytime Running Lamps (DRL) can
make it easier for others to see the
front of your vehicle during the day.
Fully functional daytime running
lamps are required on all vehicles
first sold in Canada.

6-4 Lighting
The DRL system comes on when
the following conditions are met:
.The ignition is on.
.The exterior lamps control is
in AUTO.
.The transmission is not in
P (Park), if the vehicle has 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
first sold in Canada, if parking lamps
are manually turned on, DRL will
stay on.
When it begins to get dark, the
automatic headlamp system
changes from DRL to the
headlamps.
The regular headlamp system
should be turned on when needed.
To turn off the DRL, see Exterior
Lamp Controls
on page 6‑1. Vehicles first sold in Canada
cannot turn off DRL unless certain
conditions are met. See
Exterior
Lamp Controls on page 6‑1.
Automatic Headlamp
System
When it is dark enough outside, the
automatic headlamp system turns
on after the transmission has been
shifted from P (Park) to D (Drive).
The headlamps, taillamps,
sidemarker, parking lamps, roof
marker lamps, and the instrument
panel lights turn on at normal
brightness. The radio lights will
become dimmer when the
headlights are off compared to
when the headlights are on.
The vehicle has a light sensor
located on the top of the instrument
panel. Do not cover the sensor,
or the system will be on whenever
the ignition is on. The system can turn on the
headlamps when driving in a
parking garage, through a tunnel or
when there is overcast weather.
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.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately.
Once the vehicle leaves the garage,
it takes about one minute for the
automatic headlamp system to
change to DRL if it is light outside.

8-2 Climate Controls
9(Fan Control): Turn clockwise or
counterclockwise to increase or
decrease the fan speed.
Air Delivery Mode Control: Turn
clockwise or counterclockwise to
change the direction of the airflow in
the vehicle. The airflow can be set
between modes.
To change the current mode, select
one of the following:
H (Vent): Air is directed to the
instrument panel outlets.
\(Bi-Level): Air is directed to the
instrument panel outlets, and the
remaining air to the floor outlets
and the defroster and side window
outlets. Cooler air is directed to the
upper outlets and warmer air to the
floor outlets. [
(Floor): Air is directed to the
floor outlets, side window outlets,
and defroster. Recirculation is not
available in this mode.
/ (Floor/Defog): This clears the
windows of fog and moisture. Air is
directed to the windshield, side
window, and floor outlets. The
system runs the air conditioning
unless the outside temperature is
near freezing or below. Recirculation
is not available in this mode.
0 (Defrost): This clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield and side window
outlets. The system runs the air
conditioning system unless the
outside temperature is near or
below freezing. Recirculation is
not available in this mode.
Do not drive the vehicle until all the
windows are clear. #
(Air Conditioning): Press to
turn the air conditioning system
on or off. An indicator light comes
on when the air conditioning is
turned on. This system cools and
dehumidifies the air entering the
vehicle.
The air conditioning will not
function if the fan is turned off.
If air conditioning is selected with
fan off, the indicator light flashes
three times and then turns off.
A slight change in engine
performance may occur when the
air conditioning compressor shuts
off and turns on again. This is
normal. The system is designed
to make adjustments to help with
fuel economy while still maintaining
the selected temperature.
The air conditioning system
removes moisture from the air, so
water might drip under the vehicle
while idling or after turning off the
engine. This is normal.

9-12 Driving and Operating
For mounds, washouts, loose
up-hill slopes, ditches, etc.
When wheel spin occurs as the
vehicle is moving, the driver
may notice a slight shaking or
shuddering of the vehicle. This
should be stopped as soon as
possible to prevent damage to
vehicle components. This is the
indication that a loss of traction is
occurring on this terrain. The
operator should:
1. Reduce speed and apply thebrakes.
2. Assess the terrain properly and adjust vehicle speed and gear
ranges accordingly: Four‐Wheel
High position for higher speeds
and Four‐Wheel‐Low Lock for
more torque and lower speeds.
Transmission 1 (First) gear is
generally recommended. 3. Apply slight pressure to the
brake when the shaking or
shuddering sensation is felt,
keeping the vehicle moving in
a controlled manner.
4. Be prepared to alternate between braking and
accelerating through the
adverse terrain.
Getting Familiar with Off-Road
Driving
It is a good idea to practice in an
area that is safe and close to home
before you go into the wilderness.
Off-roading requires some new and
different skills.
Tune your senses to different kinds
of signals. Your eyes need to
constantly sweep the terrain for
unexpected obstacles. Your ears
need to listen for unusual tire or
engine sounds. Use your arms,
hands, feet, and body to respond to
vibrations and vehicle bounce. Controlling the vehicle is the key to
successful off-road driving. One of
the best ways to control the vehicle
is to control the speed. At higher
speeds:
.You approach things faster and
have less time to react.
.There is less time to scan the
terrain for obstacles.
.The vehicle has more bounce
when driving over obstacles.
.More braking distance is
needed, especially on an
unpaved surface.
{WARNING
When you are driving off-road,
bouncing and quick changes in
direction can easily throw you
out of position. This could cause
you to lose control and crash.
So, whether you are driving on
or off the road, you and your
passengers should wear safety
belts.

9-36 Driving and Operating
To prevent gear damage, this
system also prevents cranking if
the engine is already running.
Engine cranking can be stopped
by turning the ignition switch to
ACC/ACCESSORY or
LOCK/OFF.
Notice: Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start
after 5‐10 seconds, especially
in very cold weather (below 0°F
or−18°C), it could be flooded
with too much gasoline. Push
the accelerator pedal all the way
to the floor and holding it there
as you hold the key in START
for a maximum of 15 seconds. Wait at least 15 seconds
between each try, to allow the
cranking motor to cool. When
the engine starts, let go of the
key and accelerator. If the
vehicle starts briefly but then
stops again, repeat the
procedure. This clears the extra
gasoline from the engine. Do not
race the engine immediately
after starting it. Operate the
engine and transmission gently
until the oil warms up and
lubricates all moving parts.
Notice: The engine is designed to
work with the electronics in the
vehicle. If you add electrical
parts or accessories, you could
change the way the engine
operates. Before adding electrical
equipment, check with your
dealer. If you do not, the engine
might not perform properly. Any
resulting damage would not be
covered by the vehicle warranty.Engine Coolant Heater
The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below −18°C (0°F). Vehicles
with an engine coolant heater
should be plugged in at least
four hours before starting. An
internal thermostat in the plug-end
of the cord may exist which will
prevent engine coolant heater
operation at temperatures
above −18°C (0° F).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap
the electrical cord. The cord
is located in the engine
compartment behind the
underhood fuse block on the
driver side of the vehicle.
