Driving and Operating 9-27
{WARNING
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running unless you
have to. 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 level ground, always
set the parking brake and move
the shift lever to P (Park). See
Shifting Into Park on page 9‑23.Make sure the shift lever is fully in
P (Park) before starting the engine.
The vehicle has an automatic
transmission shift lock control
system. The regular brake must be
fully applied first and then the shift
lever button pressed before shifting
from P (Park) when the ignition key
is in ON/RUN. If you cannot shift out
of P (Park), ease pressure on the
shift lever, then push the shift lever
all the way into P (Park) as you
maintain brake application. Then
press the shift lever button and
move the shift lever into another
gear. See
Shifting out of Park on
page 9‑24. R (Reverse):
Use this gear to
back up.
Notice: 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 on page 9‑9.

Driving and Operating 9-31
Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The switch for the
EPB is in the center console. The
EPB can always be activated,
even if the ignition is off. To avoid
draining the battery, do not cycle the
EPB too often without the engine
running. The EPB can be left
applied while the vehicle is parked.
The system has a parking brake
status light and a parking brake
warning light. SeeBrake System
Warning Light on page 5‑16. There are also Driver Information Center
(DIC) messages. See
Brake System
Messages on page 5‑25 for more
information. In case of insufficient
electrical power, the EPB cannot be
applied or released.
Before leaving the vehicle, check
the parking brake status light to
ensure the parking brake is applied.
EPB Apply
The EPB can be applied any time
the vehicle is stopped. The EPB is
applied by momentarily lifting up on
the EPB switch. Once fully applied,
the parking brake status light will be
on. While the brake is being applied,
the status light will flash until full
apply is reached. If the light does
not come on, or remains flashing,
you need to have the vehicle
serviced. Do not drive the vehicle if
the parking brake status light is
flashing. See your dealer. See
Brake System Warning Light on
page 5‑16 for more information. If the EPB is applied while the
vehicle is in motion, a chime will
sound, and a DIC message will be
displayed. See
Brake System
Messages on page 5‑25. The
vehicle will decelerate as long as
the switch is held in the up position.
Releasing the EPB switch during
the deceleration will release the
parking brake. If the switch is held
in the up position until the vehicle
comes to a stop, the EPB will
remain applied.
If the parking brake status light
flashes continuously, the EPB is
only partially applied or released,
or there is a problem with the EPB.
A DIC message will be displayed.
See Brake System Messages on
page 5‑25. If this light flashes
continuously, release the EPB, and
attempt to apply it again. If this light
continues to flash, do not drive the
vehicle. See your dealer.
If the parking brake warning light
is on, the EPB has detected an
error in another system and is
operating with reduced functionality.

9-32 Driving and Operating
To apply the EPB when this light is
on, lift up on the EPB switch and
hold it in the up position. Full
application of the parking brake by
the EPB system may take a longer
period of time than normal when
this light is on. Continue to hold the
switch until the parking brake status
light remains on. If the parking
brake warning light is on, see your
dealer.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.
EPB Release
To release the EPB, place the
ignition in the ON/RUN position,
apply and hold the brake pedal,
and push down momentarily on
the EPB switch. If you attempt to
release the EPB without the brake
pedal applied, a chime will sound,and a DIC message will be
displayed. See
Brake System
Messages on page 5‑25. The EPB
is released when the parking brake
status light is off.
If the parking brake warning light is
on, the EPB has detected an error
in another system and is operating
with reduced functionality. To
release the EPB when this light is
on, push down on the EPB switch
and hold it in the down position.
EPB release may take a longer
period of time than normal when
this light is on. Continue to hold the
switch until the parking brake status
light is off. If the light is on, see your
dealer. Notice:
Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Make sure that the parking
brake is fully released and the
brake warning light is off before
driving.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to
drive away. Avoid rapid acceleration
when the EPB is applied, to
preserve parking brake lining life.
If you are towing a trailer and
parking on a hill, see Driving
Characteristics and Towing Tips on
page 9‑47 for more information.

10-10 Vehicle Care
It is possible that, if driving under
the best conditions, the oil life
system might indicate that an oil
change is not necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and, at this time, the system must
be reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
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
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Turn the ignition to ON/RUN withthe engine off.
2. Press the DIC MENU button on the turn signal lever to enter the
Vehicle Information Menu. Use
the thumbwheel to scroll through
the menu items until you reach
REMAINING OIL LIFE.
3. Press the SET/CLR button to reset the oil life at 100%.
4. Turn the ignition to LOCK/OFF.
The system is reset when the
CHANGE ENGINE OIL SOON
message is off and the REMAINING
OIL LIFE 100% message is
displayed. If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not been reset. Repeat
the procedure.
Automatic Transmission
Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check
the transmission fluid level.
A transmission fluid leak is the
only reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer and have it repaired as soon
as possible.
The vehicle is not equipped with a
transmission fluid level dipstick.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at the dealer. Contact the
dealer for additional information.
