Maintenance
Passenger Compartment Air Filter
The filter reduces dust, pollen, and other
airborne irritants from outside air that is
pulled into the vehicle. The filter should be
replaced as part of routine scheduled
maintenance. See Maintenance Schedule
0 323. See your dealer regarding replacement of
the filter.
Service
All vehicles have a label underhood that
identifies the refrigerant used in the vehicle.
The refrigerant system should only be
serviced by trained and certified technicians.
The air conditioning evaporator should never
be repaired or replaced by one from a
salvage vehicle. It should only be replaced
by a new evaporator to ensure proper and
safe operation.
During service, all refrigerants should be
reclaimed with proper equipment. Venting
refrigerants directly to the atmosphere is
harmful to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite, or other
health-based concerns.
The air conditioning system requires periodic
maintenance. See
Maintenance Schedule
0 323.

will return to ACC/ACCESSORY and display
the message SHIFT TO PARK in the Driver
Information Center (DIC). When the vehicle
is shifted into P (Park), the ignition will
turn off.
Do not turn the engine off when the vehicle
is moving. This will cause a loss of power
assist in the brake and steering systems and
disable the airbags. If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steady pressure. Do not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving.
After shifting to N (Neutral), firmly apply
the brakes and steer the vehicle to a
safe location.
3. Come to a complete stop, shift to P (Park), and turn the ignition off. The
shift lever must be in P (Park) to turn the
ignition off.
4. Set the parking brake. See Electric

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 five to 10 seconds, especially in very cold
weather (below −18 °C or 0 °F), it could
be flooded with too much gasoline. Try
pushing the accelerator pedal all the way
to the floor and holding it there as you
press ENGINE START/STOP, for up to a
maximum of 15 seconds. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down. When
the engine starts, let go of the button
and the accelerator. If the vehicle starts
briefly but then stops again, do the
same thing. 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.

204 Driving and Operating
Stop/Start System
This vehicle has a Stop/Start system to shut
off the engine to help conserve fuel. It has
components designed for the increased
number of starts.
{Warning
The automatic engine Stop/Start feature
causes the engine to shut off while the
vehicle is still on. Do not exit the vehicle
before shifting to P (Park). The vehicle
may restart and move unexpectedly.
Always shift to P (Park), and then turn
the ignition off before exiting the vehicle.
Auto Engine Stop/Start
When the brakes are applied and the vehicle
is at a complete stop, the engine may turn
off. When stopped, the tachometer displays
AUTO STOP. See Tachometer0101. When
the brake pedal is released or the
accelerator pedal is pressed, the engine will
restart.
To maintain vehicle performance, other
conditions may cause the engine to
automatically restart before the brake pedal
is released. Auto Stops may not occur and/or auto
restarts may occur because:
.The climate control settings require the
engine to be running to cool or heat the
vehicle interior.
.The vehicle battery charge is low.
.The vehicle battery has recently been
disconnected.
.Minimum vehicle speed has not been
reached since the last Auto Stop.
.The accelerator pedal is pressed.
.The engine or transmission is not at the
required operating temperature.
.The outside temperature is not in the
required operating range.
.The vehicle is in any gear other than
D (Drive).
.Tow/Haul Mode or other driver modes
have been selected.
.The vehicle is on a steep hill or grade.
.The driver door has been opened or driver
seat belt has been unbuckled.
.The hood has been opened.
.The Auto Stop has reached the maximum
allowed time.
Engine Heater
The engine heater can provide easier
starting and better fuel economy during
engine warm-up in cold weather conditions
at or below 0 °F (−18 °C). Vehicles with an
engine heater should be plugged in at least
four hours before starting. Some models
may have an internal thermostat in the cord
which will prevent engine heater operation
at temperatures above 0 °F (−18 °C).
{Warning
Do not plug in the engine block heater
while the vehicle is parked in a garage or
under a carport. Property damage or
personal injury may result. Always park
the vehicle in a clear open area away

Driving and Operating 209
Caution
Shifting to R (Reverse) while the vehicle is
moving forward could damage the
transmission. The repairs would not be
covered by the vehicle warranty. Shift to
R (Reverse) only after the vehicle is
stopped.
To rock the vehicle back and forth to get
out of snow, ice, or sand without damaging
the transmission, see If the Vehicle Is Stuck
0 197.
N : In this position, the engine does not
connect with the wheels. To restart the
engine when the vehicle is already moving,
use N (Neutral) only.
{Warning
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is firmly on
the brake pedal, the vehicle could move
very rapidly. You could lose control and
hit people or objects. Do not shift into a
drive gear while the engine is running at
high speed.
Caution
Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may
damage the transmission. The repairs
would not be covered by the vehicle
warranty. Be sure the engine is not
running at high speed when shifting the
vehicle.
Caution
A transmission hot message may display
if the automatic transmission fluid is too
hot. Driving under this condition can
damage the vehicle. Stop and idle the
engine to cool the automatic
transmission fluid. This message clears
when the transmission fluid has cooled
sufficiently.
D : This position is for normal driving.
If more power is needed for passing, press
the accelerator pedal down.
Caution
If the vehicle does not shift gears, the
transmission could be damaged. Have the
vehicle serviced right away. If the vehicle is stopped on a hill, with your
foot off the brake pedal, the vehicle may
roll. This is normal and is due to the torque
converter designed to improve fuel economy
and performance. Use the brake to hold the
vehicle on a hill. Do not use the accelerator
pedal.
L :
This position gives you access to gear
ranges. This provides more engine braking
but lower fuel economy than D (Drive). You
can use it on very steep hills, or in deep
snow or mud. See Manual Mode0209.
Operating Modes : The transmission may
operate in a lower gear than normal to
improve vehicle performance. The engine
speed may be higher and there may be an
increase in noise during the following
conditions:
.When climbing a grade
.When driving downhill
.When driving in hot temperatures, or at
high altitude
Manual Mode
Electronic Range Select (ERS) Mode
ERS mode allows you to choose the top-gear
limit of the transmission and the vehicle's
speed while driving downhill or towing a

trailer. The vehicle has an electronic shift
position indicator within the instrument
cluster. When using the ERS mode a number
will display next to the L, indicating the
highest gear available for the range selected.
To use this feature:1. Press the shift lever button and move the shift lever to L (Low).
2. Press + (Plus) or −(Minus) on the shift
lever to increase or decrease the gear
range available.
When you shift from D (Drive) to L (Low),
the transmission will shift to a
pre-determined lower gear range. The
highest gear available for this
pre-determined range is displayed next to the L in the DIC. See
Driver Information
Center (DIC) 0111. The number displayed in
the DIC is the highest gear that the
transmission will be allowed to operate in.
This means that all gears below that
number are available. For example, when
4 (Fourth) is shown next to the L, 1 (First)
through 4 (Fourth) gears are automatically
shifted by the vehicle. The transmission will
not shift into 5 (Fifth) until the + (Plus)
button is used or you shift back into
D (Drive).
If the transmission is in 9 (ninth) gear when
L (low) is selected, a downshift to 7 (seventh)
will be commanded. If in 8 (eighth) through
2 (second), a single downshift will occur.
While in L (Low), the transmission will
prevent shifting to a lower gear range if the
engine speed is too high. You have a brief
period of time to slow the vehicle. If vehicle
speed is not reduced within the time
allowed, the lower gear range shift will not
be completed. You must further slow the
vehicle, then press −(Minus) to the desired
lower gear range.
Automatic Engine Grade Braking is not
available when the ERS is active. It is
available in D (Drive) for both normal driving and Tow/Haul Mode. While using the ERS,
cruise control and the Tow/Haul Mode can
be used. See
“Tow/Haul Mode” following.
