Vehicle Care 10-13
Automatic Transmission
Fluid
It is not necessary to check
the transmission fluid level.
A transmission fluid leak is the
only reason for fluid loss. If a leak
occurs, take the vehicle to the
dealer and have it repaired as
soon as possible.
Change the fluid at the intervals
listed inScheduled Maintenance on
page 11‑2, and be sure to use
the transmission fluid listed in
Recommended Fluids and
Lubricants on page 11‑7.
Notice: Use of the incorrect
automatic transmission fluid
may damage the vehicle, and the
damages may not be covered by
the vehicle warranty. Always use
the automatic transmission fluid
listed in Recommended Fluids
and Lubricants on page 11‑7. The transmission fluid will not
reach the end of the dipstick unless
the transmission is at operating
temperature. If you need to check
the transmission fluid level, please
take the vehicle to your dealer.
Engine Air Cleaner/Filter
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at
the scheduled maintenance
intervals and replace it at the first
oil change after each 80 000 km
(50,000 mi) interval. See
Scheduled
Maintenance on page 11‑2 for more
information. If driving in dusty/dirty
conditions, inspect the filter at each
engine oil change.
See Engine Compartment Overview
on page 10‑6 for the location of the
engine air cleaner/filter.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter,
remove the filter from the vehicle
and lightly shake the filter (away
from vehicle) to release loose dust
and dirt. If the filter remains covered
with dirt, a new filter is required.
To inspect or replace the engine air
cleaner/filter, do the following:
1. Remove the engine cover. See Engine Cover on page 10‑7.

to P (Park). Then release the
parking brake followed by the
regular brake.
Contact your dealer if service is
required.
Wiper Blade Replacement
Windshield wiper blades should
be inspected for wear or cracking.
See Scheduled Maintenance on
page 11‑2 for more information.
Replacement blades come in
different types and are removed in
different ways. To replace the wiper
blade assembly:
1. Pull the windshield wiper arm away from the windshield.
2. Press the button in the middle ofthe wiper arm connector and pull
the wiper blade away from the
arm connector.
3. Install the new wiper blade and make sure the wiper blade locks
into place.
For the proper size and type see
Maintenance Replacement Parts on
page 11‑9.
Backglass Wiper Blade
To replace the backglass wiper
blade:
1. Pull the wiper blade assembly away from the backglass.
The backglass wiper blade will
not lock in a vertical position
so care should be used when
pulling it away from the vehicle.
2. Rotate the wiper blade assembly, hold the wiper arm in
position, and push the blade
away from the wiper arm.
3. Replace the wiper blade.
4. Return the wiper arm and blade assembly to the rest position on
the glass.

for HUD or the HUD image may
look out of focus.

10-52 Vehicle Care
Tire Rotation
Tires should be rotated every
12 000 km (7,500 miles).
SeeScheduled Maintenance on
page 11‑2.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the vehicle
continues to perform most like
it did when the tires were new.
The first rotation is the most
important. See Scheduled
Maintenance on page 11‑2.
Any time you notice unusual
wear, rotate the tires as soon
as possible and check wheel
alignment. Also check for
damaged tires or wheels.
See When It Is Time for New
Tires on page 10‑53 andWheel
Replacement on page 10‑59.
When rotating the vehicle's tires,
always use the correct rotation
pattern shown here.
If the vehicle has a compact
spare tire, do not include it in
the tire rotation.
After the tires have been
rotated, adjust the front and rear
inflation pressures as shown on
the Tire and Loading Information
label. See Tire Pressure on
page 10‑45 andVehicle Load
Limits on page 9‑12. Reset the Tire Pressure Monitor
System. See
Tire Pressure
Monitor Operation on
page 10‑48.
Make certain that all wheel
nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and Specifications on
page 12‑2.
{WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle.
In an emergency, use a cloth or
a paper towel to do this; but be
sure to use a scraper or wire
brush later, if needed, to get all
the rust or dirt off. See If a Tire
Goes Flat on page 10‑61.
