JACKING AND TIRE
CHANGING
WARNING!
• Do not attempt to change a tire on theside of the vehicle close to moving traf-
fic. Pull far enough off the road to avoid
the danger of being hit when operating
the jack or changing the wheel.
• Being under a jacked-up vehicle is dan-
gerous. The vehicle could slip off the
jack and fall on you. You could be
crushed. Never put any part of your body
under a vehicle that is on a jack. If you
need to get under a raised vehicle, take
it to a service center where it can be
raised on a lift.
• Never start or run the engine while the
vehicle is on a jack.
• The jack is designed to be used as a tool
for changing tires only. The jack should
not be used to lift the vehicle for service
purposes. The vehicle should be jacked
on a firm level surface only. Avoid ice or
slippery areas.
Jack Location/Spare Tire Stowage
The jack, wheel chocks and spare tire are
stowed under the load floor behind the rear
seat.
1. Open the liftgate.
2. Lift the access cover using the load floor handle. 3. Remove the hook from the stowed posi-
tion on the back side of the load floor and
place the hook over the top body flange
and weather seal. This will hold the load
floor up while obtaining the jack and spare
tire.
4. Remove the fastener securing the jack and spare tire.
5. Remove the chocks.
6. Remove the scissors jack and wheel bolt wrench from the spare wheel as an assem-
bly. Turn the jack screw to the left to
loosen the wheel bolt wrench, and remove
the wrench from the jack assembly.
NOTE:
The jack handle attaches to the side of the
jack with two attachment points. When
the jack is partially expanded, the tension
between the two attachment points holds
the jack handle in place.
7. Remove the spare tire.

WARNING!
• If working on or near a roadway, beextremely careful of motor traffic.
• To assure that spare tires, flat or in-
flated, are securely stowed, spares must
be stowed with the valve stem facing the
ground.
CAUTION!
Do not attempt to raise the vehicle by
jacking on locations other than those indi-
cated in the Jacking Instructions for this
vehicle.
1. Remove the spare tire, jack, and wheel bolt wrench.
2. If equipped with aluminum wheels where the center cap covers the wheel bolts, use
the wheel bolt wrench to pry the center
cap off carefully before raising the
vehicle.
3. Before raising the vehicle, use the wheel bolt wrench to loosen, but not remove, the
wheel bolts on the wheel with the flat tire.
Turn the wheel bolts counterclockwise one
turn while the wheel is still on the ground. 4. Place the jack underneath the lift area
that is closest to the flat tire. Turn the jack
screw clockwise to firmly engage the jack
saddle with the lift area of the sill flange,
centering the jack saddle inside the cut-
out in the sill cladding.

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 equipment manufac-
turer’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing
devices to main structural members of the
vehicle, not to bumpers or associated brack-
ets. State and local laws regarding vehicles
under tow must be observed.
NOTE:
• You must ensure that the Auto Park Brakefeature is disabled before towing this ve-
hicle, to avoid inadvertent Electric Park
Brake engagement. The Auto Park Brake
feature is enabled or disabled via the cus-
tomer programmable features in the
Uconnect Settings.
• Vehicles with a discharged battery or total electrical failure when the electric park
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, de-
frosters, etc.) while being towed, the ignition
must be in the ON/RUN mode, not the ACC
mode.
Note that the Safehold feature will engage
the Electric Park Brake whenever the driver's
door is opened (if the battery is connected,
ignition is ON, transmission is not in PARK,
and brake pedal is released). If you are towing
this vehicle with the ignition in the ON/RUN
mode, you must manually disable the Elec-
tric Park Brake each time the driver's door is
opened, by pressing the brake pedal and then
releasing the EPB.
If the vehicle’s battery is discharged, refer to
“Gear Selector Override” in this section for
instructions on shifting the automatic trans-
mission 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 flatbed
truck, do not attach to front or rear
CAUTION!
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.
Without The Key Fob
Special care must be taken when the vehicle
is towed with the ignition in the LOCK/OFF
mode. The only approved method of towing
without the key fob is with a flatbed truck.
Proper towing equipment is necessary to pre-
vent damage to the vehicle.
Front-Wheel Drive (FWD) Models — With
Key Fob
The manufacturer recommends towing your
vehicle with all four wheels OFFthe ground
using a flatbed.

ENHANCED ACCIDENT
RESPONSE SYSTEM (EARS)
This vehicle is equipped with an Enhanced
Accident Response System.
Please refer to “Occupant Restraint Sys-
tems” in “Safety” for further information on
the Enhanced Accident Response System
(EARS) function.
EVENT DATA RECORDER
(EDR)
This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an EDR
is to record data that will assist in under-
standing how a vehicle’s systems performed
under certain crash or near crash-like situa-
tions, such as an air bag deployment or hit-
ting a road obstacle.
Please refer to “Occupant Restraint Sys-
tems” in “Safety” for further information on
the Event Data Recorder (EDR).

WARNING!
for your vehicle is also identified on the
original factory installed hydraulic mas-
ter cylinder reservoir.
• To avoid contamination from foreign
matter or moisture, use only new brake
fluid or fluid that has been in a tightly
closed container. Keep the master cylin-
der reservoir cap secured at all times.
Brake fluid in a open container absorbs
moisture from the air resulting in a lower
boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake fail-
ure. This could result in a collision.
• Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot en-
gine parts, causing the brake fluid to
catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should
be taken to avoid its contact with these
surfaces.
WARNING!
• Do not allow petroleum based fluid tocontaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This
could result in a collision.
Manual Transmission — If Equipped
Fluid Level Check
Check the fluid level by removing the fill
plug. The fluid level should be between the
bottom of the fill hole and a point not more
than 3/16 inch (4.7 mm) below the bottom of
the hole.
Add fluid, if necessary, to maintain the
proper level.
Please see your authorized dealer for service.
Automatic Transmission
Fluid Level Check
The fluid level is preset at the factory and
does not require adjustment under normal
operating conditions. Routine fluid level
checks are not required; therefore the trans-
mission has no dipstick. An authorized dealer
can check your transmission fluid level using
special service tools. If you notice fluid leak-
age or transmission malfunction, visit an au-
thorized dealer immediately to have the
transmission fluid level checked. Operating
the vehicle with an improper fluid level can
cause severe transmission damage.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An au-
thorized dealer has the proper tools to
adjust the fluid level accurately.
