One to Four Shift Light
When this light comes on, you can
only shift from 1 (First) to 4 (Fourth)
instead of 1 (First) to 2 (Second).
The light will be displayed on theinstrument panel cluster and a
message will be displayed in
the Driver Information Center.
You must complete the shift into
4 (Fourth) to turn off this feature.
This helps you get the best possible
fuel economy.
After shifting to 4 (Fourth), you may
downshift to a lower gear if you
prefer.
Notice:Forcing the shift lever
into any gear except FOURTH (4)
when the 1 TO 4 SHIFT light
comes on may damage the
transmission. Shift only from
FIRST (1) to FOURTH (4) when the
light comes on.
This light will come on when:
The engine coolant temperature
is higher than 169°F (76°C),
you are going 15 to 19 mph
(24 to 31 km/h) and
you are 21 percent throttle
or less.

Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
Driving with the park brake applied
will cause a warning chime to
sound and the Park Brake message
to appear in the DIC. The message
will remain on until:
the park brake is released
the vehicle comes to a stop.
If you are towing a trailer and you
are parking on a hill, seeTowing a
Trailer on page 9-89.
Shifting Into Park
(Automatic
Transmission)
{CAUTION
It can be dangerous to get out of
the vehicle if the shift lever is not
fully in P (Park) with the parking
brake rmly set. The vehicle can
roll. If you have left the engine
running, the vehicle can move
suddenly. You or others could be
injured. To be sure the vehicle will
not move, even when you are on
fairly level ground, use the steps
that follow. If you are pulling a
trailer, seeTowing a Trailer on
page 9-89.Use this procedure to shift into
P (Park):
1. Hold the brake pedal down and
set the parking brake.
SeeParking Brake on page 8-11
for more information.
2. Move the shift lever into P (Park)
by holding in the button on the
shift lever and pushing the
lever all the way toward the front
of the vehicle.
3. Turn the ignition key to
LOCK/OFF.
4. Remove the key and take it with
you. If you can leave the vehicle
with the ignition key in your
hand, the vehicle is in P (Park).
8-12 Driving and Operating

Parking the Vehicle
(Manual Transmission)
If the vehicle has a manual
transmission, before you get out of
the vehicle, move the shift lever into
R (Reverse), and rmly apply the
parking brake. Once the shift lever
has been placed into R (Reverse)
with the clutch pedal pressed in,
turn the ignition key to LOCK/OFF,
remove the key and release the
clutch.
If you are parking on a hill, or if the
vehicle is pulling a trailer, see
Towing a Trailer on page 9-89.
Parking Over Things
That Burn
{CAUTION
Things that can burn could touch
hot exhaust parts under the vehicle
and ignite. Do not park over
papers, leaves, dry grass, or other
things that can burn.
Engine Exhaust
{CAUTION
Engine exhaust contains Carbon
Monoxide (CO) which cannot be
seen or smelled. Exposure to CO
can cause unconsciousness and
even death.
Exhaust may enter the vehicle if:
The vehicle idles in areas
with poor ventilation (parking
garages, tunnels, deep snow
that may block underbody
airow or tail pipes).
The exhaust smells or
sounds strange or different.
(Continued)
8-14 Driving and Operating

{CAUTION
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. The brakes will have
to do all the work of slowing down
and they could get so hot that
they would not work well. You
would then have poor braking or
even none going down a hill. You
could crash. Always have the
engine running and the vehicle in
gear when going downhill.
Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in your
own lane.
Top of hills: Be alert — something
could be in your lane (stalled car,
accident).
Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the road,
creating less traction or grip. Wet ice
can occur at about 32°F (0°C) when
freezing rain begins to fall, resulting
in even less traction. Avoid driving on
wet ice or in freezing rain until roads
can be treated with salt or sand.
Drive with caution, whatever the
condition. Accelerate gently
so traction is not lost. Accelerating
too quickly causes the wheels
to spin and makes the surface under
the tires slick, so there is even
less traction.

Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that lets you know when to change
the engine oil and lter. This is
based on engine revolutions and
engine temperature, and not
on mileage. Based on driving
conditions, the mileage at which an
oil change will be indicated can
vary considerably. For the oil
life system to work properly, you
must reset the system every
time the oil is changed.
When the system has calculated
that oil life has been diminished,
it will indicate that an oil change is
necessary. The Service Engine
Oil message will be displayed.Change the oil as soon as possible
within the next 600 miles (1 000 km).
It is possible that, if you are driving
under the best conditions, the oil life
system might not indicate that an oil
change is necessary for over a year.
However, the engine oil and lter
must be changed at least once a
year and at this time the system must
be reset. Your dealer/retailer has
trained service people who will
perform this work using genuine
parts and reset the system. It is also
important to check the oil regularly
and keep it at the proper level.
If the system is ever reset
accidentally, you must change
the oil at 3,000 miles (5 000 km)
since the last oil change. Remember
to reset the oil life system whenever
the oil is changed.
How to Reset the Engine Oil
Life System
The Engine Oil Life System
calculates when to change the
engine oil and lter based on vehicle
use. Whenever the oil is changed,
reset the system so it can calculate
when the next oil change is required.
If a situation occurs where you
change the oil prior to the Service
Engine Oil message being displayed,
reset the system.
After changing the engine oil, reset
the system:
1. Turn the ignition key to ON/RUN
with the engine off.
2. Fully press and release the
accelerator pedal three times
within ve seconds.
If the Service Engine Oil
message does not appear,
the system is reset.
If the Service Engine Oil message
displays, reset the system again.

If no coolant is visible in the surge
tank, add coolant as follows:
1. Check the engine coolant
reservoir level and, if required,
top with coolant. SeeEngine
Coolant on page 9-15Engine
Coolant.
2. Locate the radiator cap.
3. Cover the cap with a thick
cloth and turn it slowly
counterclockwise and remove.4. If there is no coolant or the level is
low, slowly ll the system through
the radiator cap opening with a
50/50 mixture of clean, drinkable
water and a DEX-COOL
®coolant
until full. Wait 30 seconds for
coolant to settle and top off if the
level drops.
Do not spill coolant on the
accessory drive belts.
If a spill occurs, rinse the belt
with fresh water.
5. Start the engine.
6. With the engine idling, top off the
coolant through the radiator cap
opening until full.
Wait 30 seconds for the coolant
to settle and top off, if the
level drops.
7. Once the system is full, put the
radiator cap back on by turning
clockwise.8. Turn off the ignition.
9. Check the coolant level in the
reservoir and ll it until the
level is at the top of the dipstick.
Notice:If the pressure cap is
not tightly installed, coolant loss
and possible engine damage
may occur. Be sure the cap is
properly and tightly secured.
Pressure Cap
Notice:If the pressure cap is
not tightly installed, coolant loss
and possible engine damage
may occur. Be sure the cap is
properly and tightly secured.

3. Wipe the cap and the top of the
reservoir clean.
4. Turn the cap counterclockwise
and pull it straight up.
5. When the engine is hot, the level
should be at the hot MAX level.
When the engine is cold, the
uid level should be between
MIN and MAX on the dipstick.
6. Replace the cap.
Adding Power Steering Fluid
To determine what kind of uid
to use, seeRecommended Fluids
and Lubricants on page 11-12.
Always use the proper uid. Failure
to use the proper uid can cause
leaks and damage hoses and seals.
1. Turn the ignition to LOCK/OFF.
2. Top off with power steering
uid. Do not overll the reservoir.
