Notice: Improperly tightened
wheel nuts can lead to brake
pulsation and rotor damage. To
avoid expensive brake repairs,
evenly tighten the wheel nuts in
the proper sequence and to the
proper torque specification. See
Capacities and Specifications on
page 12‑2 for the wheel nut
torque specification.
17. Tighten the wheel nuts firmly in a crisscross sequence, as
shown.
18. Lower the jack all the way and remove the jack from under the
vehicle.
19. Tighten the wheel nuts firmly with the wheel wrench.
When reinstalling the wheel cover
or center cap on the full-size tire,
tighten all five plastic caps hand
snug with the aid of the wheel
wrench and tighten them with
the wheel wrench an additional
one‐quarter of a turn. Notice:
Wheel covers will not fit
on the vehicle's compact spare.
If you try to put a wheel cover on
the compact spare, the cover or
the spare could be damaged.
Storing a Flat or Spare Tire
and Tools
{WARNING
Storing a jack, a tire, or other
equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or
collision, loose equipment could
strike someone. Store all these in
the proper place.
Store the spare or flat tire in one of
the ways shown below. Storage
instructions will vary depending on
the bolt that came with the vehicle
and how it attaches to the vehicle.
This vehicle will have a slide in
fastener or a screw in fastener.

fastener.
2. Replace the fastener with the one provided in the foam.
3. Turn the wrench clockwise to tighten the fastener.
4. Replace the foam, jack and tools, and the tire. 5. Turn the retainer nut clockwise
to secure the tire.
6. Place the floor cover on the wheel.
Storing a Flat or Spare Tire and
Tools With a Slide In Fastener
1. If the flat tire is larger than the spare tire, use the longer
mounting bolt from the tool bag.
2. Slide the shorter bolt to removeit from the floor and insert the
longer one. 3. Replace the jack and tools in
their original storage location.
4. Place the tire, lying flat, facing up in the spare tire well.
5. Turn the retainer nut clockwise to secure the tire.
6. Place the floor cover on the wheel.
To store the compact spare tire, use
the shorter mounting bolt.
The compact spare is for temporary

Compact Spare Tire
{WARNING
Driving with more than one
compact spare tire at a time could
result in loss of braking and
handling. This could lead to a
crash and you or others could be
injured. Use only one compact
spare tire at a time.
If this vehicle has a compact spare
tire, it was fully inflated when the
vehicle was new; however, it can
lose air after a time. Check the
inflation pressure regularly. It should
be 420 kPa (60 psi).
Stop as soon as possible and check
that the spare tire is correctly
inflated after installing the spare on
the vehicle. The compact spare is
designed to perform well at speeds
up to 105 km/h (65 mph) for
distances up to 5 000 km (3,000 mi), so a trip can be completed and the
full-size tire repaired or replaced
when possible. However, the
compact spare tire will last longer
and be in good shape if it is
replaced as soon as possible.
Notice:
When the compact spare
is installed, do not take the
vehicle through an automatic car
wash with guide rails. The
compact spare can get caught on
the rails which can damage the
tire, wheel, and other parts of the
vehicle.
Do not use the compact spare on
other vehicles.
Do not mix the compact spare tire or
wheel with other wheels or tires.
They will not fit. Keep the spare tire
and its wheel together.
Notice: Tire chains will not fit the
compact spare. Using them can
damage the vehicle and can
damage the chains too. Do not
use tire chains on the compact
spare.

Jump Starting (with or
without eAssist)
For more information about the
vehicle battery, seeBattery on
page 10‑29.
If the battery has run down, try to
use another vehicle and some
jumper cables to start your vehicle.
Be sure to use the following steps to
do it safely.
{WARNING
Batteries can hurt you. They can
be dangerous because:
.They contain acid that can
burn you.
.They contain gas that can
explode or ignite.
.They contain enough
electricity to burn you.
If you do not follow these steps
exactly, some or all of these
things can hurt you. Notice:
Ignoring these steps
could result in costly damage to
the vehicle that would not be
covered by the warranty.
Trying to start the vehicle by
pushing or pulling it will not
work, and it could damage the

These locations are used instead of
a direct connection to the battery.
1. Check the other vehicle. It musthave a 12-volt battery with a
negative ground system.
Notice: Only use a vehicle that
has a 12-volt system with a
negative ground for jump
starting. If the other vehicle does
not have a 12-volt system with a
negative ground, both vehicles
can be damaged.
2. Position the two vehicles so that they are not touching.
3. To avoid the possibility of the vehicles rolling, set the parking
brake firmly on both vehicles
involved in the jump start
procedure. Put an automatic
transmission in P (Park) or a
manual transmission in Neutral
before setting the parking brake. Notice:
If any accessories are left
on or plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible,
turn off or unplug all accessories
on either vehicle when jump
starting the vehicle.
4. Turn the ignition to LOCK/OFF
and switch off all lights and
accessories in both vehicles,
except the hazard warning
flashers if needed.
{WARNING
An electric fan can start up even
when the engine is not running
and can injure you. Keep hands,
clothing and tools away from any
underhood electric fan.
{WARNING
Using a match near a battery can
cause battery gas to explode.
People have been hurt doing this,
and some have been blinded.
Use a flashlight if you need more
light.
Be sure the battery has enough
water. You do not need to add
water to the battery installed in
your new vehicle. But if a battery
has filler caps, be sure the right
amount of fluid is there. If it is low,
add water to take care of that
first. If you do not, explosive gas
could be present.
Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, flush
the place with water and get
medical help immediately.

{WARNING
Fans or other moving engine
parts can injure you badly. Keep
your hands away from moving
parts once the engine is running.
5. Connect one end of the redpositive (+) cable to the jump
start positive (+) post (A). Use a
remote positive (+) terminal if the
vehicle has one. 6. Do not let the other end of the
red positive (+) cable touch
metal. Connect it to the
positive (+) terminal of the good
battery (B). Use a remote
positive (+) terminal if the vehicle
has one.
7. Connect one end of the black negative (–) cable to the
negative (–) terminal of the
good battery (C). Use a remote
negative (−) terminal if the
vehicle has one.
Do not let the other end touch
anything until the next step. The
other end of the negative (–)
cable does not go to the dead
battery. It goes to a heavy,
unpainted metal engine part or
to a remote negative (–) terminal
on the vehicle with the dead
battery. 8. Connect the other end of the
black negative (–) cable to an
unpainted heavy metal engine
part (D) away from the dead
battery, but not near engine
parts that move.
9. Start the engine in the vehicle with the good battery and run
the engine at idle speed for at
least four minutes.
10. Try to start the vehicle that had the dead battery. If it will not
start after a few tries, it
probably needs service.

connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.

jumper cables in the correct
order, making sure that the
cables do not touch each other or
other metal.
