brake status light is off. If either light
stays on after release is attempted,
see your dealer.
Caution
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.
The EPB can also be used to
prevent roll back for vehicles with a
manual transmission taking off on a
hill. When no roll back is desired, an
applied EPB will allow both feet to
be used for the clutch and
accelerator pedals in preparation for
starting the vehicle moving in theintended direction. In this case,
there is no need to push the switch
to release the EPB.
If parking on a hill, or if the vehicle
is pulling a trailer, see
Driving
Characteristics and Towing
Tips 0221.
Brake Assist
The Brake Assist feature is
designed to assist the driver in
stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsation or
pedal movement during this time is
normal and the driver should
continue to apply the brake pedal as the driving situation dictates. The
Brake Assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly
decreased.
Hill Start Assist (HSA)
This vehicle has a Hill Start Assist
(HSA) feature, which may be useful
when the vehicle is stopped on a
grade (less than 10%). This feature
is designed to prevent the vehicle
from rolling, either forward or
rearward, during vehicle drive off.
After the driver completely stops
and holds the vehicle in a complete
standstill on a grade, HSA will be
automatically activated and the DIC
will display the HILL START ASSIST
ACTIVE message. During the
transition period between when the
driver releases the brake pedal and
starts to accelerate to drive off on a
grade, HSA holds the braking
pressure to ensure that there is no
rolling. The brakes will automatically
release after three seconds or when
the accelerator pedal is applied
within the three-second window.

brakes might have to be used so
much that they would get hot and no
longer work well.
The vehicle can tow in D (Drive).
Use a lower gear if the transmission
shifts too often.
When towing at high altitude on
steep uphill grades, engine coolant
boils at a lower temperature than at
normal altitudes. If the engine is
turned off immediately after towing
at high altitude on steep uphill
grades, the vehicle could show
signs similar to engine overheating.
To avoid this, let the engine run
while parked, preferably on level
ground, with the transmission in
P (Park) for a few minutes before
turning the engine off. If the
overheat warning comes on, see
Engine Overheating0244.Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn
the wheels into the curb if
facing downhill or into traffic if
facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the brake pedal
until the chocks absorb
the load.
4. Reapply the brake pedal. Then apply the parking brake and
shift into P (Park). 5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal
while you:
1.1. Start the engine.
1.2. Shift into a gear.
1.3. Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See the
Maintenance Schedule 0305.
Things that are especially important
in trailer operation are automatic
transmission fluid, engine oil, axle
lubricant, belts, cooling system, and
brake system. Inspect these before
and during the trip.

The TPMS sensor matching
process is:1. Set the parking brake.
2. Put an automatic transmission in P (Park) or a manual
transmission in 1 (First) or
R (Reverse).
3. Turn the ignition to ON/RUN with the engine off or place the
vehicle power mode in ON/
RUN/START. See Ignition
Positions (Keyless Access)
0 186 orIgnition Positions (Key
Access) 0188.
4. Use the MENU button to select the Vehicle Information Menu
in the Driver Information
Center (DIC).
5. Use the thumbwheel to scroll to the Tire Pressure Menu Item
screen.
6. Press the SET/CLR button to begin the sensor matching
process.
A message asking if the
process should begin should
appear. 7. Press the SET/CLR button
again to confirm the selection.
The horn sounds twice to
signal the receiver is in relearn
mode and the TIRE
LEARNING ACTIVE message
displays on the DIC screen.
8. Start with the driver side front tire.
9. Place the relearn tool against the tire sidewall, near the valve
stem. Then press the button to
activate the TPMS sensor.
A horn chirp confirms that the
sensor identification code has
been matched to this tire and
wheel position.
10. Proceed to the passenger side front tire, and repeat the
procedure in Step 8.
11. Proceed to the passenger side rear tire, and repeat the
procedure in Step 8.
12. Proceed to the driver side rear tire, and repeat the procedure
in Step 8. The horn sounds two
times to indicate the sensor
identification code has been matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the DIC
display screen goes off.
13. Turn the ignition to LOCK/OFF or press STOP to turn the
ignition off.
14. Set all four tires to the recommended air pressure
level as indicated on the Tire
and Loading Information label.
Tire Inspection
We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected
for signs of wear or damage at
least once a month.
Replace the tire if:
.The indicators at three or
more places around the tire
can be seen.
.There is cord or fabric
showing through the tire's
rubber.

be badly injured or killed if the
vehicle slips off the jack. If a jack
is provided with the vehicle, only
use it for changing a flat tire.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place, well off the road,
if possible. Turn on the hazard
warning flashers. See Hazard
Warning Flashers 0134.
{Warning
Changing a tire can be
dangerous. The vehicle can slip
off the jack and roll over or fall
causing injury or death. Find a
level place to change the tire. To
help prevent the vehicle from
moving:
1. Set the parking brake firmly. (Continued)
Warning (Continued)
2. Put an automatictransmission in P (Park) or a
manual transmission in
1 (First) or R (Reverse).
3. Turn off the engine and do not restart while the vehicle
is raised.
4. Do not allow passengers to remain in the vehicle.
5. Place wheel blocks, if equipped, on both sides of
the tire at the opposite
corner of the tire being
changed.
When the vehicle has a flat tire (2),
use the following example as a
guide to assist in the placement of
the wheel blocks (1), if equipped.
