Cruise Control
With cruise control, you can maintain a speed of
approximately 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This is helpful on
long trips. Cruise control does not work at speeds
below about 25 mph (40 km/h). When cruise control is
on, you will see a CRUISE light on the instrument panel
cluster.When you apply your brakes, the cruise control shuts off.
{CAUTION:
·Cruise control can be dangerous where
you can't drive safely at a steady speed.
So, don't use your cruise control on
winding roads or in heavy traffic.
·Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
needless wheel spinning, and you could
lose control. Don't use cruise control on
slippery roads.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. See
Traction
Control System (TCS) on page 4-9. When road
conditions allow you to safely use it again, you may turn
the cruise control back on.
3-12

Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you're
not using cruise, you might hit a button and go
into cruise when you don't want to. You could
be startled and even lose control. Keep the
cruise control switch off until you want to use
cruise control.
The buttons to operate cruise control are located on the
steering wheel.1. Press the CRUISE ON/OFF button, located on the
bottom left of the steering wheel, to turn cruise
control on. An indicator light will come on to show
that the cruise control is on.
2. Get up to the speed you want.
3. Press the SET/CST (coast) button located on the
bottom right of the steering wheel. The CRUISE
light will display on the instrument panel cluster.
4. Remove your foot from the accelerator pedal.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This shuts off the
cruise control. But you don't need to reset it.
Once the vehicle is traveling approximately 25 mph
(40 km/h) or more, you can press the RES/ACC
(resume/accelerate) button to return to your desired
preset speed. The CRUISE light will be displayed again.
The vehicle will return to and stay at your preset
speed. If you press and hold the RES/ACC button, the
vehicle speed will increase until you release the
button or apply the brake. Unless you want to go faster,
do not press and hold the RES/ACC button.
3-13

Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
·Use the accelerator pedal to get to the higher
speed. Press the SET/CST button, then release the
button and the accelerator pedal. You will now
cruise at the higher speed.
·Press the RES/ACC button. Hold it there until you get
up to the speed that you want, and then release the
button. To increase your speed in very small
amounts, brie¯y press the RES/ACC button and then
release it. Each time you do this, your vehicle will
speed up approximately 1 mph (1.6 km/h).
The accelerate feature will only work after you have set
the cruise control speed by pressing the SET/CST button.
Reducing Speed While Using Cruise
Control
There are two ways to reduce your speed while using
cruise control:
·Press the SET/CST button until you reach the lower
speed you want, then release it.
·To slow down in very small amounts, push the
SET/CST button brie¯y. Each time you do this,
the vehicle will slow down approximately 1 mph
(1.6 km/h).
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the hills.
When going up steep hills, you may have to step on the
accelerator pedal to maintain your speed. When going
downhill, you may have to brake or shift to a lower gear to
keep your speed down. Applying the brake or shifting into
a lower gear will take you out of cruise control. If you
need to apply the brake or shift to a lower gear due to the
grade of the downhill slope, you may not want to attempt
to use your cruise control feature.
Ending Cruise Control
To turn off the cruise control, step lightly on the brake
pedal, or press the CRUISE ON/OFF button on the
steering wheel.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.

Cruise Control Light
This light comes on
whenever the cruise
control system is in use. It
will go out when the
system is turned off.
See ªCruise Controlº under
Turn Signal/Multifunction
Lever on page 3-8for more information.
Fuel Gage
The fuel gage shows
approximately how much
fuel is in the tank. It
works only when the
ignition is in ON.
If the fuel supply gets down to approximately 3 gallons
(11.4 L) of fuel remaining in the tank, the FUEL
LEVEL LOW message will appear on the Driver
Information Center (DIC) and a single chime will sound.
On the digital cluster, if the fuel is less than
approximately 1.2 gallons (4.7 L) the E segment on the
gage will ¯ash. The fuel range on the Driver Information
Center (DIC) will display ªLO.º

Traction Control System (TCS)
Your vehicle has a traction control system that limits
wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that one or both of the front wheels are spinning or
beginning to lose traction. When this happens,
the system works the front brakes and reduces engine
power to limit wheel spin.
The TRACTION ENGAGED message will display on the
Driver Information Center when the traction control
system is limiting wheel spin. See
DIC Warnings and
Messages on page 3-60. You may feel or hear the
system working, but this is normal.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
reengage the cruise control. See ªCruise Controlº under
Turn Signal/Multifunction Lever on page 3-8.This warning light will come on to let you know if there's
a problem with your traction control system.
See
Traction Control System (TCS) Warning Light on
page 3-48. When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.
The traction control system automatically comes
on whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to. You
should turn the system off if your vehicle ever gets stuck
in sand, mud or snow and rocking the vehicle is
required. See ªRocking Your Vehicle To Get It Outº

If You Are Stuck: In Sand, Mud, Ice or Snow on

Engine Cooling System Inspection
Inspect the hoses and have them replaced if they
are cracked, swollen or deteriorated. Inspect all pipes,
®ttings and clamps; replace as needed. Clean the
outside of the radiator and air conditioning condenser.
To help ensure proper operation, a pressure test of
the cooling system and pressure cap is recommended
at least once a year.
Throttle System Inspection
Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts
as needed. Replace any components that have high
effort or excessive wear. Do not lubricate accelerator
and cruise control cables.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
cha®ng, etc. Inspect disc brake pads for wear and rotors
for surface condition. Inspect other brake parts,
including calipers, parking brake, etc. You may need to
have your brakes inspected more often if your driving
habits or conditions result in frequent braking.
