FIRST (1): This position gives you even more power
than SECOND (2). You can use it on very steep hills,
or in deep snow or mud. (If the shift lever is put in
FIRST (1), the transaxle won't shift into first gear until
the vehicle is going slowly enough.)
NOTICE:
If your front wheels can't turn, don't try to drive.
This might happen if you were stuck in very deep
sand or mud or were up against a solid object.
You could damage your transaxle.
Also, if you stop when going uphill, don't hold
your vehicle there with only the accelerator
pedal. This could cause overheating and damage
the transaxle. Use your brakes to hold your
vehicle in position on a hill.
Performance Shifting (DTS Only)
When your vehicle detects a change in driving
conditions, it will automatically initiate the appropriate
performance shift mode. When this occurs the gear
display on the instrument panel cluster will change to
indicate that the transaxle has shifted to a different gear.
For example, the gear display on the cluster may
indicate D, 3, 2, or 1 even though the gearshift is still
in DRIVE (D). Once the performance shift mode ends,
the gear display on the instrument panel cluster will
return to normal.

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 ªTraction
Control Systemº in the Index. When road conditions
allow you to safely use it again, you may turn the cruise
control back on.Setting Cruise Control
CAUTION:
If you leave your cruise control switch 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.
1. Press the CRUISE ON/OFF button to turn cruise
control on. (The button is located on the bottom left
of the steering wheel.) 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. (The button is
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.

3-9 Ventilation System
Your vehicle's flow-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the heater or the air
conditioning fan is running.
The front outlets are located in the center and at each
side of the instrument panel. You can adjust the
direction of airflow by moving the center control levers
or you can stop the airflow by moving the thumbwheels
located on each side of the outlets downward.Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of the windows.

Keep the air path under the front seats clear of
objects. This helps circulate air throughout
your vehicle.
Passenger Compartment Air Filter
This ventilation system includes a charcoal air filter that
helps to remove dust, pollen, etc. from the air flowing
into your vehicle. A restriction in the airflow coming
into the passenger compartment could be the result of
dirt in the filter. For more information, see ªPassenger
Compartment Air Filter Replacementº in the Index.
Also see the Maintenance Schedule booklet for when to
change the filter.

3-10 HVAC Steering Wheel Controls
(If Equipped)
Some heating and cooling
controls can be adjusted at
the steering wheel. Other
touch controls operate some
audio controls. See ªAudio
Steering Wheel Controlsº in
the Index.
FAN SPEED: Press the up arrow lever to
increase the fan speed and the down arrow lever to
decrease fan speed.
TEMP: Press the up arrow lever to increase
the temperature and the down arrow lever to
decrease temperature.
Climate Control Personalization
(If Equipped)
With this feature, your vehicle will recall the latest
climate control settings as adjusted the last time your
vehicle was operated. This feature allows two different
drivers to store and recall their own climate control
settings. The settings recalled by the climate control
system are determined by which remote keyless entry
transmitter (ª1º or ª2º) was used to enter the vehicle.
The number on the back of the remote keyless entry
transmitter corresponds to driver 1 or to driver 2. After
the unlock button is pressed on the remote keyless entry
transmitter or the ignition key is placed in the ignition
(the ignition must be turned to OFF), the climate control
settings will automatically adjust to where they were
last set. The settings can also be changed by briefly
pressing the memory seat buttons 1 or 2 located on the
driver's door.

Here's how anti-lock works. Let's say the road is wet.
You're driving safely. Suddenly an animal jumps out in
front of you.
You slam on the brakes and continue braking.
Here's what happens with ABS.
A computer senses that wheels are slowing down. If one
of the wheels is about to stop rolling, the computer will
separately work the brakes at each front wheel and at
both rear wheels.The anti
-lock system can change the brake pressure faster
than any driver could. The computer is programmed to
make the most of available tire and road conditions.
This can help you steer around the obstacle while
braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.

4-9
Remember: Anti-lock doesn't change the time you need
to get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front of you, you won't have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you have
anti
-lock brakes.
Using Anti
-Lock
Don't pump the brakes. Just hold the brake pedal down
firmly and let anti
-lock work for you. You may hear the
anti
-lock pump or motor operate, and feel the brake
pedal pulsate, but this is normal.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Traction Control System
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 ªDriver Information
Center Messagesº in the Index. 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
in the Index.United States Canada
This warning light will come on to let you know if
there's a problem with your traction control system.
See ªTraction Control System Warning Lightº in the
Index. When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.

4-11 Steering Tips
Driving on Curves
It's important to take curves at a reasonable speed.
A lot of the ªdriver lost controlº accidents mentioned
on the news happen on curves. Here's why:
Experienced driver or beginner, each of us is subject
to the same laws of physics when driving on curves.
The traction of the tires against the road surface makes it
possible for the vehicle to change its path when you turn
the front wheels. If there's no traction, inertia will keep
the vehicle going in the same direction. If you've ever
tried to steer a vehicle on wet ice, you'll understand this.
The traction you can get in a curve depends on the
condition of your tires and the road surface, the angle
at which the curve is banked, and your speed. While
you're in a curve, speed is the one factor you can control.
Suppose you're steering through a sharp curve. Then you
suddenly accelerate. Both control systems
-- steering and
acceleration
-- have to do their work where the tires meet
the road. Adding the sudden acceleration can demand too
much of those places. You can lose control. Refer to
ªTraction Control Systemº in the Index.What should you do if this ever happens? Ease up on
the accelerator pedal, steer the vehicle the way you want
it to go, and slow down.
If you have Stabilitrak

, you may see the STABILITY
SYS ENGAGED message on the Driver Information
Center. See ªStability Sys Engaged Messageº in
the Index.
Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds are
based on good weather and road conditions. Under less
favorable conditions you'll want to go slower.
If you need to reduce your speed as you approach a
curve, do it before you enter the curve, while your front
wheels are straight ahead.
Try to adjust your speed so you can ªdriveº through
the curve. Maintain a reasonable, steady speed. Wait
to accelerate until you are out of the curve, and then
accelerate gently into the straightaway.
To help you steer in the direction you want to go,
during certain sharp or sudden cornering maneuvers,
gear selection is controlled. This will maximize the
available drive wheel torque and minimize the transaxle
response time and shift activity. During this kind of
maneuver, the transaxle shifts automatically as vehicle
speed changes.
