298 STARTING AND OPERATING
Brake Alert
NOTE:
The “Brake!” Screen in the instrument cluster display is a
warning for the driver to take action and does not necessarily
mean that the Forward Collision Warning system is
applying the brakes autonomously.
Trailer Detect — If Equipped
When a trailer is detected, the ACC system automatically
defaults to the longest setting (four bars). The setting can be
overridden by pushing the Distance Button on the steering
wheel. Overtake Aid
When driving with ACC engaged and following a vehicle,
the system will provide an additional acceleration up to the
ACC set speed to assist in passing the vehicle. This addi -
tional acceleration is triggered when the driver utilizes the
left turn signal and will only be active when passing on the
left hand side.
ACC Operation At Stop
In the event that the ACC system brings your vehicle to a
standstill while following a target vehicle, if the target
vehicle starts moving within two seconds of your vehicle
coming to a standstill, your vehicle will resume motion
without the need for any driver action.
If the target vehicle does not start moving within two
seconds of your vehicle coming to a standstill, then ACC will
cancel and the driver must take over braking. When the
target vehicle drives off, ACC can be resumed by releasing
the brake and pushing the RES (+) button.

STARTING AND OPERATING 347
(Continued) Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact spare
tire.
• Do not drive more than 50 mph (80 km/h) when towing
while using a full size spare tire.WARNING!
• Make certain that the load is secured in the trailer and
will not shift during travel. When trailering cargo that
is not fully secured, dynamic load shifts can occur that
may be difficult for the driver to control. You could lose
control of your vehicle and have a collision.
• When hauling cargo or towing a trailer, do not overload
your vehicle or trailer. Overloading can cause a loss of
control, poor performance or damage to brakes, axle,
engine, transmission, steering, suspension, chassis
structure or tires.
• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
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. For
four-wheel drive vehicles, make sure the transfer case
is not in NEUTRAL. Always, block or "chock" the
trailer wheels.
• GCWR must not be exceeded. • Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
• GVWR
• GTW
• GAWR
• Tongue weight rating for the trailer hitch utilized. WARNING! (Continued)

Recreational towing (for two-wheel drive models) is allowed
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.
2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Place automatic trans -
mission in PARK.
4. Properly secure the rear wheels to the dolly, following the
dolly manufacturer's instructions.
5. Turn the ignition OFF and remove the key fob.
6. Install a suitable clamping device, designed for towing, to
secure the front wheels in the straight position. Recreational Towing — Four-Wheel Drive Models
NOTE:
Both the manual shift and electronic shift transfer cases must
be shifted into NEUTRAL (N) for recreational towing. Auto -
matic transmissions must be shifted into PARK for recre -
ational towing. Refer to the following for the proper transfer
case NEUTRAL (N) shifting procedure for your vehicle. CAUTION!
• Towing with the rear wheels on the ground will cause
severe transmission damage. Damage from improper
towing is not covered under the New Vehicle Limited
