move the rear wiper control to OFF
to disable the rear wiper. In some
vehicles, if the transmission is in
N (Neutral) and the vehicle speed is
very slow, the rear wiper will
automatically park. The wiper operations return to
normal when the transmission is no
longer in N (Neutral) or the vehicle
speed has increased.
Reverse Gear Wipes
If the rear wiper control is off, the
rear wiper will automatically operate
continuously when the vehicle is in
R (Reverse) and the front
windshield wiper is performing low
or high speed wipes. If the rear
wiper control is off, the vehicle is in
R (Reverse), and the front
windshield wiper is performing
interval wipes, then the rear wiper
automatically performs interval
wipes.
This feature can be turned on or off.
See
Vehicle Personalization 0151.
The windshield washer reservoir is
used for the windshield and the rear
window. Check the fluid level in the
reservoir if either washer is not
working. See Washer Fluid 0276.

Maintenance When Trailer
Towing
The vehicle needs service more
often when used to tow trailers. See
theMaintenance Schedule 0350.
It is especially important to check
the automatic transmission fluid,
engine oil, axle lubricant, belts,
cooling system, and brake system
before and during each trip.
Check periodically that all nuts and
bolts on the trailer hitch are tight.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. See Engine Overheating
0 275.
Trailer Towing
Caution

correctly, follow the directions in
this section and see your dealer
for important information about
towing a trailer with the vehicle.
Trailer Weight
{Warning

for your vehicle.
Safe trailering requires monitoring
the weight, speed, altitude, road
grades, outside temperature,
dimensions of the front of the trailer,
and how frequently the vehicle is
used to tow a trailer.

include engine revolutions, engine
temperature, and miles driven.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably. For
the oil life system to work properly,
the system must be reset every time
the oil is changed.
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A CHANGE ENGINE
OIL SOON message comes on.
Change the oil as soon as possible
within the next 1 000 km (600 mi).
It is possible that, if driving under
the best conditions, the oil life
system might indicate that an oil
change is not necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and, at this time, the system must
be reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Display the REMAINING OIL LIFE on the DIC. See Driver
Information Center (DIC) (Base
and Midlevel) 0144 or
Driver Information Center (DIC)
(Uplevel) 0147.
2. Press and hold the thumbwheel on the DIC while
the Oil Life display is active.
3. Confirm yes, and the oil life will change to 100%. The oil life system can also be reset
as follows:
1. Place the ignition in Service Mode. See Ignition Positions
0 192.
2. Display REMAINING OIL LIFE on the DIC menu. See Driver
Information Center (DIC) (Base
and Midlevel) 0144 or
Driver Information Center (DIC)
(Uplevel) 0147.
3. Fully press and release the accelerator pedal three times
within five seconds.
4. If the display changes to 100%, the system is reset.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not been reset. Repeat
the procedure.

CHANGE message displays, the
engine air filter should be replaced
at the next engine oil change.
When the REPLACE ENGINE AIR
FILTER SOON message displays,
the engine air filter should be
replaced at the earliest
convenience. The system must be
reset after the engine air filter is
changed.
If the CHECK AIR FILTER SYSTEM
message displays, see your dealer.
