{WARNING
Batteries have acid that can burn
you and gas that can explode.
You can be badly hurt if you are
not careful. SeeJump Starting
(On-board with eAssist Only) on
page 10‑89 orJump Starting (with
or without eAssist) on page 10‑91
for tips on working around a
battery without getting hurt.
Infrequent Usage: Remove the
12‐volt battery black, negative (−)
cable from the battery to keep the
battery from running down.
Extended Storage: Remove the
12‐volt battery black, negative (−)
cable from the battery or use a
battery trickle charger.
Remember to reconnect the battery
when ready to drive the vehicle.
Starter Switch Check
{WARNING
When you are doing this
inspection, the vehicle could
move suddenly. If the vehicle
moves, you or others could be
injured.
1. Before starting this check, be sure there is enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular brake.
See Parking Brake on
page 9‑34.
Do not use the accelerator
pedal, and be ready to turn off
the engine immediately if it
starts. 3. For automatic transmission
vehicles, try to start the engine
in each gear. The vehicle
should start only in P (Park) or
N (Neutral). If the vehicle starts
in any other position, contact
your dealer for service.
For manual transmission
vehicles, put the shift lever in
Neutral, push the clutch pedal
down halfway, and try to start
the engine. The vehicle should
start only when the clutch pedal
is pushed down all the way to
the floor. If the vehicle starts
when the clutch pedal is not
pushed all the way down,
contact your dealer for service.

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.

procedure may be repeated
again. If the vehicle start is still
unsuccessful, the jump start can be
attempted using the following jump
starting procedure under
“Jump
Starting (with or without eAssist).”
On‐board jump starting may be
unavailable due to the 12-volt
battery charge level, the eAssist
battery charge level, power
capability, or an issue with the
eAssist system. In these cases, the
display will not be available because
of the power issue, or the DIC will
display JUMP START DISABLED

Jump Starting (with or

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

10-92 Vehicle Care
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.

cables do not touch each other or
other metal.
Jumper Cable Removal
