This vehicle has an airbag system. Before attempting to
do your own service work, seeServicing Your
Airbag-Equipped Vehicle on page 1-67.
Keep a record with all parts receipts and list the mileage
and the date of any service work performed. See
Maintenance Record on page 7-17.
Adding Equipment to the Outside of
the Vehicle
Things added to the outside of the vehicle can affect the
airow around it. This can cause wind noise and can
affect fuel economy and windshield washer performance.
Check with your dealer/retailer before adding equipment
to the outside of the vehicle.
Fuel
Use of the recommended fuel is an important part of the
proper maintenance of this vehicle. To help keep the
engine clean and maintain optimum vehicle
performance, we recommend the use of gasoline
advertised as TOP TIER Detergent Gasoline.
This vehicle can use either unleaded gasoline or
ethanol fuel containing up to 85% ethanol (E85). See
Gasoline Octane on page 6-5andFuel E85 (85%
Ethanol) on page 6-8.
Gasoline Octane
Use premium unleaded gasoline with a posted octane
rating of 91 or higher. You can also use regular
unleaded gasoline rated at 87 octane or higher, but the
vehicle’s acceleration could be slightly reduced, and
you might notice a slight audible knocking noise,
commonly referred to as spark knock. If the octane is
less than 87, you might notice a heavy knocking
noise when you drive. If this occurs, use a gasoline
rated at 87 octane or higher as soon as possible.
Otherwise, you could damage the engine. If you are
using gasoline rated at 87 octane or higher and you hear
heavy knocking, the engine needs service.
6-5

Do not top off the brake uid. Adding uid does not
correct a leak. If uid is added when the linings
are worn, there will be too much uid when new brake
linings are installed. Add or remove brake uid, as
necessary, only when work is done on the brake
hydraulic system.
{CAUTION:
If too much brake uid is added, it can spill on the
engine and burn, if the engine is hot enough. You
or others could be burned, and the vehicle could
be damaged. Add brake uid only when work is
done on the brake hydraulic system. See
“Checking Brake Fluid” in this section.
When the brake uid falls to a low level, the brake
warning light comes on. SeeBrake System Warning
Light on page 3-33.
Refer to the Maintenance Schedule to determine when
to check the brake uid. SeeScheduled Maintenance
on page 7-4.
Checking Brake Fluid
Check brake uid by looking at the brake uid reservoir.
SeeEngine Compartment Overview on page 6-14.
The uid level should be
above MIN. If it is not,
have the brake hydraulic
system checked to
see if there is a leak.
After work is done on the brake hydraulic system,
make sure the level is above the MIN but not over the
MAX mark.

{CAUTION:
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.
{CAUTION:
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 ashlight 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 ller caps, be
sure the right amount of uid is there. If it is low,
add water to take care of that rst. If you do not,
explosive gas could be present.
CAUTION: (Continued)
CAUTION: (Continued)
Battery uid contains acid that can burn you. Do
not get it on you. If you accidentally get it in your
eyes or on your skin, ush the place with water
and get medical help immediately.
{CAUTION:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.
5. Check that the jumper cables do not have loose or
missing insulation. If they do, you could get a
shock. The vehicles could be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+) will go to
positive (+) or to a remote positive (+) terminal if
the vehicle has one. Negative (−) will go to a heavy,
unpainted metal engine part or to a remote
negative (−) terminal if the vehicle has one.
