Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle’s
GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight, axle-by-axle and side-by-side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before
driving. If weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load is within
the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.NOTE:
•
Refer to the “Vehicle Certification Label” affixed to the
rear of the driver’s door for your vehicle’s GVWR and
GAWRs.
• Refer to the “Tire Placard” for your vehicle’s proper
tire pressure.
TRAILER TOWING
Trailer towing with this vehicle is not recommended.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Recreational towing (with all four wheels on the ground,
or using a towing dolly) is NOT ALLOWED. The only
acceptable method for towing this vehicle (behind an-
other vehicle) is on a vehicle trailer with all four wheels
OFF the ground.

CAUTION!
•When “rocking” a stuck vehicle by shifting be-
tween DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
• Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no trans-
mission shifting occurring).
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.
MANUAL PARK RELEASE — 8 SPEED

WARNING!
Always secure your vehicle by fully applying the
parking brake, before activating the Manual Park
Release. Activating the Manual Park Release will
allow your vehicle to roll away if it is not secured by
the parking brake or by proper connection to a tow

vehicle. Activating the Manual Park Release on an
unsecured vehicle could lead to serious injury or
death for those in or around the vehicle.
In order to move the vehicle in cases where the transmis-
sion will not shift out of PARK (such as a dead battery),
a Manual Park Release is available.
Follow these steps to use the Manual Park Release:
1. Firmly apply the parking brake.
2. Remove the console storage bin. 3. Remove plastic cover under the bin by using the slotprovided to access the Manual Park Release lever.
4. Using a small screwdriver or similar tool, fish the tether strap up through the opening in the console
base.

5. Insert the screwdriver into the slot in the center of thelever, and disengage the lever locking tab by pushing
it to the right.
6. While holding the locking tab in the disengaged position, pull the tether strap to rotate the lever up and
rearward, until it locks in place in the vertical position. The vehicle is now out of PARK and can be moved.
Release the parking brake only when the vehicle is
securely connected to a tow vehicle.
To Reset The Manual Park Release:
1. Push the latch (at the base of the lever, on the rear side) rearward (away from the lever) to unlatch the lever.

2. Rotate the Manual Park Release lever forward anddown, to its original position, until the locking tab
snaps into place to secure the lever.
3. Pull up gently on the tether strap to confirm that the lever is locked in its stowed position.
4. Tuck the tether strap into the base of the console. Reinstall the Manual Park Release cover and the
console storage bin.TOWING A DISABLED VEHICLE

Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equip-
ment manufacturer ’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing device to
main structural members of the vehicle, not to bumpers
or associated brackets. State and local laws regarding
vehicles under tow must be observed.
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.
If the key fob is unavailable, or the vehicle’s battery is
discharged, refer toManual Park Release in this section
for instructions on shifting the transmission out of PARK
for towing.CAUTION!
• DO NOT use sling-type equipment when towing.
Vehicle damage may occur.
• When securing the vehicle to a flatbed truck, do not
attach to front or rear suspension components.
Damage to your vehicle may result from improper
towing.
• The manufacturer does not recommend towing this
vehicle using a tow dolly. Vehicle damage may
occur.
The manufacturer recommends towing your vehicle with
all four wheels OFF the ground using a flatbed. If flatbed
equipment is not available, and the transmission is
operable, the vehicle may be flat towed (with all four
wheels on the ground) under the following conditions:

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light (MIL)”. It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emissions control system. It
could also affect fuel economy and driveability.
The vehicle must be serviced before any emissions
tests can be performed.
• If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Onboard Diagnostic System (OBD II)
Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to
