GENERAL INFORMATION
Note: Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked as soon as possible. If the
vehicle has continuous vibration or shudder
in the steering wheel while braking, have the
system checked as soon as possible.
All standard equipment brakes are
self-adjusting. Automatic adjustment,
when required, occurs whenever you apply
and release the brakes during forward or
reverse operation.
Know the required stopping distances for
all driving conditions you may encounter.
For longer brake lining life, take full
advantage of engine braking power when
coming to a stop.
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
If the brakes do not grip well:
• Check brake adjustment.
• Check the brake linings for excessive
wear.
• Check the system air pressure on
vehicles with air brakes.
• Let the brakes cool if you have been
using them excessively, as in mountain
driving or after several fast, high-speed
stops.
• If you have been driving through deep
water, gently apply the brakes several
times while your vehicle is moving
slowly.
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
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking.
If the light does not illuminate
during start up, remains on or
flashes, the system may be
disabled. 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.
E210335
If you connect a PLC trailer with
the ignition on, the trailer ABS
light also illuminates. If the light
fails to illuminate, if it remains on after you
start the vehicle or continues to flash, have
the system serviced immediately.
See Warning Lamps and Indicators
(page 66).

Brakes

E209041
If the system is disabled, normal
braking is still effective. If the
brake warning lamp illuminates
with the parking brake released, have the
system checked immediately. 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.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock brake system does not
eliminate the risks 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 may travel further.
Maintain pressure on the brake pedal. You
may also hear a noise from the system. This
is normal.
PARKING BRAKE
Hydraulic Brakes (If Equipped)
WARNING: Always set the parking
brake and leave your vehicle with the
transmission in park (P).
WARNING: This control is for
parking only. Do not leave the vehicle
unattended after setting the parking
brake without placing the transmission
in park (P). We recommend using wheel
chocks for hilly or off-road
circumstances.
WARNING: Unexpected and
possibly sudden vehicle movement may
occur if you do not take these
precautions.
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.
Apply the parking brake whenever the
vehicle is parked. To set the parking brake,
pull the handle up until it snaps into the
locked position.
When the parking brake is out of
adjustment, seek service immediately.

The parking brake warning lamp
in the instrument cluster
illuminates, and remains
illuminated (when you switch on the
ignition), until you release the parking
brake.

Brakes

Push the palm release lever (A) on the
parking brake handle (B) and push down
as far as possible to release the brake.
Driving with the parking brake on causes
the brakes to wear out quickly and reduces
fuel economy.
We recommend you not use the parking
brake to stop a moving vehicle. However,
if the normal brakes fail, you can use the
parking brake to stop your vehicle in an
emergency. Since the parking brake only
applies retardation to the rear wheels, the
vehicle's stopping distance increases
greatly and the handling of your vehicle is
adversely affected.
Releasing Spring Manually
WARNING: Do not attempt to
disassemble the parking brake air
chamber under any circumstances as
this may cause serious injury.
WARNING: Block the wheels to
help prevent the vehicle from moving.
WARNING: Unexpected and
possibly sudden vehicle movement may
occur if you do not take these
precautions.
If you release hydraulic pressure from the
spring brake chamber, the power spring
applies the brake. If the hydraulic pressure
can be re-established, you must release
the spring brake in order to move your
vehicle.
Air Brakes (If Equipped)
WARNING: This control is for
parking only. Do not leave the vehicle
unattended after setting the parking
brake without placing the transmission
in park (P). We recommend using wheel
chocks for hilly or off-road
circumstances.
If the service brakes fail to operate while
your vehicle is moving, you can make an
emergency stop with the parking brake.
Since the parking brake only applies
stopping power to the rear wheels, your
vehicle’s stopping distance greatly
increases and the handling of your vehicle
is adversely affected. Make repairs
immediately to an inoperative air brake
system circuit.

The radar sensor has a limited field of view.
It may not detect vehicles at all or detect
a vehicle later than expected in some
situations. The lead vehicle graphic does
not illuminate if the system does not
detect a vehicle in front of you.
Detection issues can occur:
When driving on a different line
than the vehicle in front. A
With vehicles that edge into your
lane. The system can only detect
these vehicles once they move
fully into your lane. B
There may be issues with the
detection of vehicles in front
when driving into and coming out
of a bend or curve in the road. CIn these cases, the system may brake late
or unexpectedly. You should stay alert and
take action when necessary. If something
hits the front end of your vehicle or damage
occurs, the radar-sensing zone may
change. This could cause missed or false
vehicle detection.
System Not Available
Conditions that can cause the system to
deactivate or prevent the system from
activating when requested include:
• A blocked sensor.
• High brake temperature.
• A failure in the system or a related
system.
Blocked Sensor

Cruise Control - Vehicles With: Adaptive Cruise Control

A message displays if something obstructs
the radar signals from the sensor. The
sensor is in the lower grille. The system
cannot detect a vehicle ahead and does
not function when something blocks the
sensor.Note:You cannot see the sensor. It is
behind a fascia panel.
Keep the front of your vehicle free of dirt,
metal badges or objects. Vehicle front
protectors and aftermarket lights may also
block the sensor.
Possible causes and actions for the blocked sensor message displaying:
Action Cause
Clean the grille surface in front of the radar
or remove the object causing the obstruc-
tion. The surface of the radar is dirty or
obstructed
Wait a short time. It may take several
minutes for the radar to detect that it is free
from obstruction. The surface of the radar is clean but the
message remains in the display.
Do not use the system in these conditions
because it may not detect any vehicles
ahead. Heavy rain or snow is interfering with the
radar signals
Do not use the system in these conditions
because it may not detect any vehicles
ahead. Water, snow or ice on the surface of the
road may interfere with the radar signals.
Do not use the system in these conditions
because it may not detect any vehicles
ahead. You are in a desert or remote area with no
other vehicles and no roadside objects.
Due to the nature of radar technology, it is possible to get a blockage warning with no
actual block. A false blocked condition either self-clears, or clears after you restart your
vehicle.
