0 264. In addition to the engine oil life
system monitoring the oil life, additional
maintenance is recommended. See
Maintenance Schedule 0330.
The Oil Life display must be reset after each
oil change. It will not reset itself. Do not
reset the Oil Life display accidentally at any
time other than when the oil has just been
changed. It cannot be reset accurately until
the next oil change. To reset, see Engine Oil
Life System 0266.
Engine Air Filter Life : Displays an estimate
of the engine air filter’s remaining useful life
and the state of the system. Engine Air
Filter Life 95% means 95% of the current air
filter life remains. Messages are displayed
based on the engine air filter life and the
state of the system. When the REPLACE AT
NEXT OIL CHANGE message displays, the
engine air filter should be replaced at the
time of the next oil change. When the
REPLACE NOW message displays, the engine
air filter should be replaced as soon as
possible. To reset, see Engine Air Filter Life
System 0267. Fuel Economy :

fluid in either degrees Celsius (°C) or degrees
Fahrenheit (°F).
Oil Temperature : Displays the current oil
temperature in either degrees Celsius (°C) or
degrees Fahrenheit (°F).
Tire Pressure : Shows the approximate
pressures of all four tires. Tire pressure is
displayed in either kilopascal (kPa) or in
pounds per square inch (psi). If the pressure
is low, the value for that tire is shown in
amber. See Tire Pressure Monitor System

2. Push plastic hooks back to engage grilleslats. It is recommended to start with
the lower hooks at the center of the
grille.
3. Repeat for all hooks to fully engage cover to grille.
For vehicles equipped with a front license
plate bracket, only the outer clips will be
engaged on the upper row. Ensure the
top center portion of the cover is
positioned securely behind the license
plate bracket.
4. Make sure all clips remain engaged during installation. Cover should be
stretched to a tight fit when properly
installed.
Engine Heater
The engine heater, if available, can help in
cold weather conditions at or below
−18 °C (0 °F) for easier starting and better
fuel economy during engine warm-up. Plug
in the engine heater at least four hours
before starting the vehicle. An internal
thermostat in the plug end of the cord will
prevent engine heater operation at
temperatures above −18 °C (0 °F).
{Warning
Do not plug in the engine block heater
while the vehicle is parked in a garage or
under a carport. Property damage or
personal injury may result. Always park
the vehicle in a clear open area away
from buildings or structures.
To Use the Engine Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. The cord is located on the
passenger side of the compartment near
the air cleaner/filter. Check the heater cord for damage. If it is
damaged, do not use it. See your dealer
for a replacement. Inspect the cord for
damage yearly.
3. Plug it into a normal, grounded 110-volt AC outlet.
{Warning
Improper use of the heater cord or an
extension cord can damage the cord and
may result in overheating and fire.
.Plug the cord into a three-prong
electrical utility receptacle that is
protected by a ground fault detection
function. An ungrounded outlet could
cause an electric shock.
.Use a weatherproof, heavy-duty,
15 amp-rated extension cord if needed.
Failure to use the recommended
extension cord in good operating
condition, or using a damaged heater
or extension cord, could make it
overheat and cause a fire, property
damage, electric shock, and injury.

Doing Your
Own Service Work 0261.
Maintenance Schedule
Tire Rotation and Required Services
Every 12 000 km (7,500 mi)
Tires are rotated to achieve a more uniform
wear for all tires. The first rotation is the
most important.
Anytime unusual wear is noticed, rotate the
tires as soon as possible, check for proper
tire inflation pressure, and check for
damaged tires or wheels. If the unusual
wear continues after the rotation, check the wheel alignment. See
When It Is Time for
New Tires 0298 and
Wheel Replacement 0302.
.Perform Multi-Point Vehicle Inspection.
See Multi-Point Vehicle Inspection (MPVI)
0 332.
.Lubricate body components. See Exterior
Care 0321.
Additional Required Services —Normal
Service
Every 12 000 km (7,500 mi)
.Check engine oil level and oil
life percentage. If needed, change engine
oil and filter, and reset oil life system. Or
when the CHANGE ENGINE OIL SOON
message displays, have the engine oil and
filter changed within the next 1 000 km
(600 mi). If driven under the best
conditions, the engine oil life system may
not indicate the need for vehicle service
for up to a year. The engine oil and filter
must be changed at least once a year and
the oil life system must be reset. Your
trained dealer technician can perform this
work. If the engine oil life system is reset
accidentally, service the vehicle within
5 000 km (3,000 mi) since the last service.
