{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.
Caution
Ignoring these steps could result in
costly damage to the vehicle that
would not be covered by the vehicle
warranty. Trying to start the vehicle
by pushing or pulling it will not
work, and it could damage the
vehicle.
1. Discharged Battery Remote Positive Terminal
2. Discharged Battery Negative Grounding Point
3. Good Battery Negative Terminal
4. Good Battery Positive Terminal
The jump start positive terminal (4)
and negative post (3) are on the
battery of the vehicle providing the

terminal.
1. Check the other vehicle. It must have a 12-volt battery with a
negative ground system.
Caution
If the other vehicle does not have a
12-volt system with a negative

cause unintended acceleration and/
or increased stopping distance
which can cause a crash and injury.
Make sure the floor mat does not
interfere with the pedals.
Use the following guidelines for
proper floor mat usage.
.The original equipment floor mats
were designed for your vehicle.
If the floor mats need replacing, it

pedals.
Cleaning Rubber Floor Mats
(All-Weather Mats and Floor
Liners)
{Warning
Do not use cleaners that contain
silicone, wax-based products,
or cleaners that increase gloss on
rubber floor mats/liners. These
cleaners can permanently change
the appearance and feel of the
rubber and can make the floor
mats/liners slippery. Your foot
could slip while operating the
vehicle, and you could lose control,
resulting in a crash. You or others
could be injured.
Use a soft cloth and/or a brush
dampened with water to remove dust
and loose dirt. For more thorough
cleaning, use a mild soap solution.
