10-22 Vehicle Care
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible
in the coolant surge tank. If the
coolant inside the coolant surge
tank is boiling, do not do anything
else until it cools down. If coolant
is visible but the coolant level is not
at or above the cold fill mark, add
a 50/50 mixture of clean, drinkable
water and DEX-COOL coolant at the
coolant surge tank, but be sure the
cooling system is cool before this is
done. SeeEngine Overheating on
page 10‑23 for more information.
The coolant reservoir is located
on the passenger side of the
engine compartment. See Engine
Compartment Overview on
page 10‑10 for more information
on location. The coolant level should be at
or above the cold fill line on the
coolant surge tank. If it is not,
there could be a leak in the
cooling system.
How to Add Coolant to the
Coolant Surge Tank
{WARNING
You can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene glycol
and it will burn if the engine parts
are hot enough. Do not spill
coolant on a hot engine.
Notice: This vehicle has a
specific coolant fill procedure.
Failure to follow this procedure
could cause the engine to
overheat and be severely
damaged.
{WARNING
The electric cooling fans under
the hood can start up even when
the engine is not running and
can cause injury. Keep hands,
clothing, and tools away from
any underhood electric fan.
{WARNING
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. They are
under pressure, and if you
turn the surge tank pressure
cap —even a little —they can
come out at high speed. Never
turn the cap when the cooling
system, including the surge tank
pressure cap, is hot. Wait for the
cooling system and surge tank
pressure cap to cool if you ever
have to turn the pressure cap.

Vehicle Care 10-27
Checking Brake Fluid
Check brake fluid by looking at the
brake fluid reservoir. SeeEngine
Compartment Overview on
page 10‑10.
With the vehicle not running for at
least one minute, the maximum fluid
level (A) is at the top of the reservoir
body. With the vehicle running, the
fluid level should be in the proper
operating range (B) between the
MIN and MAX marks. 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, with the vehicle running, is
in the proper operating range (B)
between the MIN and MAX marks.
What to Add
Use only new DOT 3 brake
fluid from a sealed container.
See
Recommended Fluids and
Lubricants on page 11‑6.
Always clean the brake fluid
reservoir cap and the area
around the cap before removing it.
This helps keep dirt from entering
the reservoir.
{WARNING
With the wrong kind of fluid in
the brake hydraulic system,
the brakes might not work well.
This could cause a crash. Always
use the proper brake fluid. Notice
.Using the wrong fluid
can badly damage brake
hydraulic system parts.
For example, just a few
drops of mineral-based oil,
such as engine oil, in the
brake hydraulic system can
damage brake hydraulic
system parts so badly that
they will have to be replaced.
Do not let someone put in
the wrong kind of fluid.
.If brake fluid is spilled on the
vehicle's painted surfaces,
the paint finish can be
damaged. Be careful not
to spill brake fluid on the
vehicle. If you do, wash
it off immediately.

11-2 Service and Maintenance
{WARNING
Performing maintenance work can
be dangerous. Some jobs can
cause serious injury. Perform
maintenance work only if you
have the required know-how and
the proper tools and equipment.
If in doubt, see your dealer to
have a qualified technician do
the work. SeeDoing Your Own
Service Work on page 10‑8.
At your dealer, you can be
certain that you will receive the
highest level of service available.
Your dealer has specially trained
service technicians, uses genuine
replacement parts, as well as,
up‐to‐date tools and equipment
to ensure fast and accurate
diagnostics. The proper replacement parts,
fluids, and lubricants to use are
listed in
Recommended Fluids
and Lubricants on page 11‑6 and
Maintenance Replacement Parts on
page 11‑7. We recommend the use
of genuine parts from your dealer.
Rotation of New Tires
To maintain ride, handling, and
performance of the vehicle, it is
important that the first rotation
service for new tires be performed.
Tires should be rotated every
12 000 km/7,500 mi. See Tire
Rotation on page 10‑61.
Scheduled

more information.
.Fluids visual leak check. A leak
in any system must be repaired
and the fluid level checked.

.Check the engine oil filter for
corrosion if driving in a corrosive
environment, such as areas of
high humidity, along an ocean
coast, and/or areas that apply
road salt during winter.
Have the engine oil and filter
changed if the filter shows signs
of corrosion. After each oil and
filter change, the oil life system
must be reset. See Engine Oil
Life System on page 10‑15.
.Cooling systems inspection.
Visually inspect the hoses,
pipes, fittings, and clamps.
Replace, if needed.
.Windshield wiper blade
inspection for wear, cracking,
or contamination and windshield
and wiper blade cleaning,
if contaminated. See Exterior
Care on page 10‑89. Worn
or damaged wiper blade
replacement. See Wiper Blade
Replacement on page 10‑31.
.Engine air cleaner filter
inspection. See Engine Air
Cleaner/Filter on page 10‑16.
.Brake system inspection.
See your dealer.
.Steering and suspension
inspection. Visual inspection
for damaged, loose, or missing
parts or signs of wear.
.Body hinges and latches and
key lock cylinders lubrication.
See Recommended Fluids
and Lubricants on page 11‑6.
More frequent lubrication may
be required when the vehicle
is exposed to a corrosive
environment, such as areas of
high humidity, along an ocean
coast, and/or areas that apply
road salt during winter. Applying
silicone grease on weatherstrips
with a clean cloth makes them
last longer, seal better, and not
stick or squeak.
.Restraint system component
check. See Safety System
Check on page 3‑23.
