NOTE:Any chassis/suspension or tire size modifications
to the vehicle will effect the performance of the Adaptive
Cruise Control and Forward Collision Warning System.
Activating Adaptive Cruise Control (ACC)
You can only engage ACC if the vehicle speed is above
0 mph (0 km/h).
The minimum Set Speed for the ACC system is 20 mph
(32 km/h).
When the system is turned on and in the READY state, the
Electronic Vehicle Information Center (EVIC) or Driver
Information Display (DID) displays “ACC Ready.”
When the system is OFF, the EVIC/DID displays “Adap-
tive Cruise Control (ACC) Off.”
NOTE: You cannot engage ACC under the following
conditions:
• When in Four-Wheel Drive Low.

•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
• After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will vary its assist to provide

hydroplaning. ESC also cannot prevent accidents
resulting from loss of vehicle control due to inap-
propriate driver input for the conditions. Only a
safe, attentive, and skillful driver can prevent acci-
dents. The capabilities of an ESC equipped vehicle
must never be exploited in a reckless or dangerous
manner which could jeopardize the user ’s safety or
the safety of others.
• Vehicle modifications, or failure to properly main-
tain your vehicle, may change the handling charac-
teristics of your vehicle, and may negatively affect
the performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect
(Continued)
WARNING! (Continued)
ESC performance. Improperly inflated and un-
evenly worn tires may also degrade ESC perfor-
mance. Any vehicle modification or poor vehicle
maintenance that reduces the effectiveness of the
ESC system can increase the risk of loss of vehicle
control, vehicle rollover, personal injury and death.
ESC Operating Modes
NOTE:Depending upon model and mode of operation,
the ESC system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. When-
ever the vehicle is started, the ESC system will be in this
mode. This mode should be used for most driving
conditions. Alternate ESC modes should only be used for
specific reasons as noted in the following paragraphs.
528 STARTING AND OPERATING
CAUTION!(Continued)
tire chains or traction devices are used with origi-
nal equipment size tires.
• Damage to Four Wheel Drive (4WD) Trailhawk
Models may result if tire chains or traction devices
are used with original equipment size tires.
WARNING!
Using tires of different size and type (M+S, Snow)
between front and rear axles can cause unpredictable
handling. You could lose control and have a collision.
CAUTION!
To avoid damage to your vehicle or tires, observe the
following precautions:
• Because of restricted traction device clearance be-
tween tires and other suspension components, it is
important that only traction devices in good condi-
tion are used. Broken devices can cause serious
damage. Stop the vehicle immediately if noise
occurs that could indicate device breakage. Remove
the damaged parts of the device before further use.
• Install device as tightly as possible and then re-
tighten after driving about ½ mile (0.8 km).
• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.
•
Do not drive for a prolonged period on dry
pavement.

included on this label and indicates the Month, Day and
Hour of manufacture. The bar code that appears on the
bottom of the label is your VIN.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo.
The label also specifies maximum capacities of front and
rear axle systems (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.
Payload
The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the
driver, all passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles or suspension
components sometimes specified by purchasers for in-
creased durability does not necessarily increase the vehi-
cle’s GVWR.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.

• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to
the frame or hook retainers of the vehicle hitch.
Cross the chains under the trailer tongue and allow
enough slack for turning corners.
• Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. Put the tow vehicle transmission in
PARK. Always, block or chockthe trailer wheels.
• GCWR must not be exceeded.

WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause damage, or
even failure, of the axle and tires. A tire could
explode and injure someone. Do not spin your vehi-
cle’s wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without stop-
ping when you are stuck and do not let anyone near
a spinning wheel, no matter what the speed.
RECOVERY STRAP — IF EQUIPPED
Your vehicle may be included with a recovery strap.
Recovery straps do not act like traditional tow straps,
chains, or winch cables.
WARNING!
Recovery straps should only be used in emergencies to
rescue stranded vehicles. Only use Recovery straps on
vehicles that fit within the recommended GVW of your
recovery strap. Only attach recovery straps to OE
recommended anchor points or emergency towing an-
chor points. Never attach to tow ball or vehicle tie
down point, these are not designed for this purpose.
Never attach to vehicle steering, drive train, or any
other suspension components. NEVER pull a strap
over sharp edges or abrasive surfaces that can damage
the recovery strap. NEVER use a damaged strap, it has
reduced strength. DO NOT attempt to repair straps.
ONLY persons involved in the recovery should be in
either vehicle. No passengers. Anyone inside the ve-
hicles can be struck by strap recoil, causing serious
injury. MOVE bystanders at least 40 feet from the
recovery area when using the recovery strap.
650 WHAT TO DO IN EMERGENCIES
•Vehicles with a discharged battery or total electrical
failure when the electric parking brake (EPB) is engaged,
will need a wheel dolly or jack to raise the rear wheels
off the ground when moving the vehicle onto a flatbed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position. Note that the Safehold
feature will engage the Electric Park Brake whenever the
driver’s door is opened (if the ignition is ON, transmis-
sion is not in PARK, and brake pedal is released). If you
are towing this vehicle with the ignition in the ON/RUN
position, you must manually disable the Electric Park
Brake each time the driver’s door is opened, by pressing
the brake pedal and then pushing the EPB switch down.
If the key fob is unavailable, or the vehicle’s battery is
discharged, refer to “Shift Lever Override” in this section
for instructions on shifting the transmission out of PARK
so that the vehicle can be moved.
CAUTION!
• Do not use sling type equipment when towing.
Vehicle damage may occur.
• When securing the vehicle to a flat bed truck, do
not attach to front or rear suspension components.
Damage to your vehicle may result from improper
towing.
• Ensure that the Electric Park Brake is released, and
remains released, while being towed.
Front-Wheel Drive (FWD) Models
The manufacturer recommends towing your vehicle with
all four wheels OFFthe ground using a flatbed.
If flatbed equipment is not available, this vehicle must
towed with the front wheels OFF the ground (using a
towing dolly, or wheel lift equipment with the front
wheels raised).
