Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches

282 STARTING AND OPERATING

•New vehicles from the dealership must have at least 30
miles (48 km) accumulated before the ParkSense Active
Park Assist system is fully calibrated and performs
accurately. This is due to the system’s dynamic vehicle
calibration to improve the performance of the feature.
The system will also continuously perform the dynamic
vehicle calibration to account for differences such as
over or under inflated tires and new tires.
Enabling And Disabling The ParkSense Active Park
Assist System
The ParkSense Active Park Assist system can be
enabled and disabled with the ParkSense Active
Park Assist switch, located on the switch panel
below the Uconnect display.
To enable the ParkSense Active Park Assist system, push
the ParkSense Active Park Assist switch once (LED turns
on).
To disable the ParkSense Active Park Assist system, push
the ParkSense Active Park Assist switch again (LED turns
off). The ParkSense Active Park Assist system will turn off
automatically for any of the following conditions:
•
The parking maneuver is completed.
• Vehicle speed greater than 18 mph (30 km/h) when
searching for a parking space.
• Vehicle speed greater than 5 mph (7 km/h) during active
steering guidance into the parking space.
• Touching the steering wheel during active steering guid-
ance into the parking space.
• Pushing the ParkSense Front and Rear Park Assist
switch.
• Driver’s door is opened.
• Rear liftgate is opened.
• Electronic Stability Control/Anti-lock Braking System
intervention.

STARTING AND OPERATING 333

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.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo loaded
into the vehicle. The front and rear curb weight values are
determined by weighing your vehicle on a commercial
scale before any occupants or cargo are added.
Loading
The actual total weight and the weight of the front and rear
of your vehicle at the ground can best be determined by
weighing it when it is loaded and ready for operation.The entire vehicle should first be weighed on a commercial
scale to insure that the GVWR has not been exceeded. The
weight on the front and rear of the vehicle should then be
determined separately to be sure that the load is properly
distributed over the front and rear axle. Weighing the
vehicle may show that the GAWR of either the front or rear
axles has been exceeded but the total load is within the
specified GVWR. If so, weight must be shifted from front to
rear or rear to front as appropriate until the specified
weight limitations are met. Store the heavier items down
low and be sure that the weight is distributed equally. Stow
all loose items securely before driving.
Improper weight distributions can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.

•Check the trailer tires for proper tire inflation pressures
before trailer usage.
• Check for signs of tire wear or visible tire damage before
towing a trailer. Refer to “Tires” in “Servicing And
Maintenance” for the proper inspection procedure.
• When replacing tires, refer to “Tires” in “Servicing And
Maintenance” for the proper tire replacement proce-
dures. Replacing tires with a higher load carrying capac-
ity will not increase the vehicle’s GVWR and GAWR
limits.
Towing Requirements — Trailer Brakes
•Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible per-
sonal injury.
• An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu-
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic
brake controller is not required. •
Trailer brakes are recommended for trailers over
1,000 lbs (453 kg) and required for trailers in excess of
2,000 lbs (907 kg).
CAUTION!
If the trailer weighs more than 1,000 lbs (453 kg)
loaded, it should have its own brakes and they should
be of adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal
effort, and longer stopping distances.
372 STARTING AND OPERATING

NOTE:
•When towing your vehicle, always follow applicable
state and provincial laws. Contact state and provincial
Highway Safety offices for additional details.
• Vehicles equipped with Quadra-Lift must be placed in
Transport Mode before tying them down (from the
body) on a trailer or flatbed truck. Refer to “Quadra-
Lift” in “Starting and Operating” for more information.
If the vehicle cannot be placed in Transport mode (for
example, engine will not run), tie-downs should be
fastened over the tires using specific straps (not to the
body). Failure to follow these instructions may cause
fault codes to be set and/or cause loss of proper
tie-down tension.
Recreational Towing — Two Wheel Drive Models
DO NOT flat tow this vehicle. Damage to the drivetrain
will result.
Recreational towing (for two-wheel drive models) is al-
lowed ONLY if the rear wheels are OFF the ground. This
may be accomplished using a tow dolly or vehicle trailer. If
using a tow dolly, follow this procedure: 1. Properly secure the dolly to the tow vehicle, following
the dolly manufacturer’s instructions.
NOTE: If vehicle is equipped with Quadra-Lift air suspen-
sion, ensure the vehicle is set to Normal Ride Height.
2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Shift the transmission into PARK.
4. Turn the ignition OFF.
5. Properly secure the rear wheels to the dolly, following the dolly manufacturer ’s instructions.
6. Install a suitable clamping device, designed for towing, to secure the front wheels in the straight position.
