AUTOMATIC TRANSMISSION
PRECAUTIONS
WARNING: Apply the parking
brake, shift into park (P), switch the
ignition off and remove the key before
you leave your vehicle. Failure to follow
this instruction could result in personal
injury or death. WARNING:
Do not use tow/haul
when the road surface is slippery. Failure
to follow this instruction could result in
the loss of control of your vehicle. WARNING:
When your vehicle is
stationary, keep the brake pedal fully
pressed when shifting gears. Failure to
follow this instruction could result in
personal injury, death or property
damage. WARNING:
Do not apply the brake
pedal and accelerator pedal
simultaneously. Applying both pedals
simultaneously for more than a few
seconds will limit engine performance,
which may result in difficulty maintaining
speed in traffic and could lead to serious
injury.
AUTOMATIC TRANSMISSION
POSITIONS
PARK (P)
This position locks the driveline and
prevents the wheels from turning. Come
to a complete stop before putting your
vehicle into and out of park (P). The electric parking brake could apply
when you shift to park (P) without the
brake pedal fully pressed. The electric
parking brake applies when you shift to
park (P) on large slopes. The electric
parking brake releases with the drive away
release function or manually. See Electric
Parking Brake
(page 311).
Note: A warning tone sounds if you open
the driver door and you have not shifted the
transmission selector to park (P).
See
Automatic Return to Park (P) (page 286).
REVERSE (R) WARNING:
Move the transmission
selector lever to reverse (R) only when
your vehicle is stationary and the engine
is at idle speed.
This position allows your vehicle to move
backward. Come to a complete stop
before shifting into and out of reverse (R).
NEUTRAL (N) WARNING:
In neutral (N) your
vehicle is free to roll.
In neutral (N) power is not transmitted to
the driven wheels.
DRIVE (D)
Drive (D) is the normal driving position, and
allows automatic upshifts and downshifts
through all available gears.
MANUAL (M)
To select manual mode press the (M)
button on the shifter.

Note:
Do not store objects in the selector
lever stow bin, and be sure that the bottom
selector lever tray mat is flat inside the
selector lever stow bin.
Note: If there are objects in the stow bin
while stowing the selector lever, the selector
lever could come back to the upright park
(P) position.
MANUAL PARK RELEASE
WHAT IS MANUAL PARK RELEASE
Manual park release allows you to move
your transmission out of the park (P)
position in the event of an electrical
malfunction or emergency.
MANUAL PARK RELEASE
PRECAUTIONS WARNING: When doing this
procedure, you need to take the
transmission out of park (P) which
means your vehicle can roll freely. To
avoid unwanted vehicle movement,
always fully apply the parking brake prior
to doing this procedure. Use wheels
chocks if appropriate. WARNING:
If the parking brake is
fully released, but the brake warning
lamp remains illuminated, the brakes
may not be working properly. Have your
vehicle checked as soon as possible. WARNING:
Do not drive your
vehicle until you verify that the
stoplamps are working.
Use the manual park release to move your
transmission from the park (P) position in
the event of an electrical malfunction or
emergency. See
Emergency Towing
(page 492).
Note: Do not engage the manual park
release with the engine on.
USING MANUAL PARK RELEASE
Activating the Manual Park
Release Cable
1. Apply the parking brake. See Electric
Parking Brake
(page 311).
Note: If vehicle battery is dead, for example,
no electrical power available, an external
power source may be required to apply the
parking brake.
2. Locate the manual park release cable access cover at the bottom of the
driver dash lower panel, under the
steering wheel.

(P) position and is free to roll. 6.
With your foot still fully applied on the
brake pedal, disengage the parking
brake. See Electric Parking Brake
(page 311).
7. Your vehicle remains in neutral (N) for emergency towing purposes.

BRAKE PRECAUTIONS
WARNING: Driving your vehicle
with the warning lamp on is dangerous.
A significant decrease in braking
performance may occur. It may take you
longer to stop your vehicle. Have your
vehicle checked as soon as possible.
Driving extended distances with the
parking brake engaged can cause brake
failure and the risk of personal injury.
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when leaving a car wash or
driving from standing water to dry the
brakes.
Note: Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, the stoplamps
could flash during heavy braking. Following
this the hazard warning flashers could also
turn on when your vehicle comes to a stop.
ANTI-LOCK BRAKING SYSTEM
ANTI-LOCK BRAKING SYSTEM
LIMITATIONS
The anti-lock braking system does not
eliminate the risk of crash when:
• You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal could pulse and travel further.
Maintain pressure on the brake pedal. BRAKE OVER ACCELERATOR
- RAPTOR
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Move the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Note:
Certain drive modes can disable
brake over accelerator for off-road driving.
BRAKE OVER ACCELERATOR
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Move the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.

BRAKES –
TROUBLESHOOTING
BRAKES – WARNING LAMPS
If the ABS indicator illuminates
when you are driving, this
indicates a malfunction. Your
vehicle continues to have normal braking
without the anti-lock braking system
function. See an authorized dealer.
It also momentarily illuminates when you
switch the ignition on to confirm the lamp
is functional. If it does not illuminate when
you switch the ignition on, or begins to
flash at any time, have the system checked
by an authorized dealer. The brake indicator momentarily
illuminates when you switch the
ignition on to confirm the lamp
is functional. It may also illuminate when
you apply the parking brake and the
ignition is on. If it illuminates when your
vehicle is moving, make sure the parking
brake is disengaged. If the parking brake
is disengaged, this indicates low brake fluid
level or a brake system fault. See an
authorized dealer.
BRAKES – FREQUENTLY ASKED
QUESTIONS
Is it normal for my brakes to make
noise?
Occasional brake noise is normal. If a
metal-to-metal, continuous grinding,
or continuous squeal sound is present,
the brake lining could be worn-out.
Have the system checked by an
authorized dealer. There is an electrical motor sound
when I press on the brake pedal or
activate the park brake switch. Is this
normal?
Yes, those sounds are the electronic
brake booster or the electronic park
brake operating.
Note: Brake dust could accumulate on the
wheels, even under normal driving
conditions. Some dust is normal as the
brakes wear and does not contribute to
brake noise. See Cleaning Wheels (page
535).
