With Rainsense, if the transmission is in
N (Neutral) and the vehicle speed is very
slow, the wipers will automatically stop at
the base of the windshield.
The wiper operations return to normal when
the transmission is no longer in N (Neutral)
or the vehicle speed has increased.
Rear Window Wiper/Washer
The rear window wiper/washer controls are
on the end of the windshield wiper lever.
Turn the controls to adjust the setting.
OFF :Turns the wiper off.
INT : Turns on the rear wiper with a delay
between wipes.
ON : Turns on the rear wiper.
1:Push the windshield wiper lever
forward to spray washer fluid on the rear
window and the rear camera lens,
if equipped. See Rear Camera Mirror 029.
The wipers will clear the rear window and
either stop or return to your preset speed.
For more washer cycles, push and hold the
lever.
The rear window wiper/washer will not
operate if the liftgate is open or ajar. If the
liftgate is opened while the rear wiper is on,
the wiper returns to the parked position and
stops.
Rear Wiper Arm Assembly Protection
When using an automatic car wash, 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 under the rear
spoiler.
The wiper operations return to normal when
the transmission is no longer in N (Neutral)
or the vehicle speed has increased.
Auto Wipe in Reverse Gear
If the rear wiper control is off, the rear
wiper will automatically operate
continuously when the transmission is in R (Reverse), and the front windshield wiper
is performing low or high speed wipes.
If the rear wiper control is off, the
transmission is in R (Reverse), and the front
windshield wiper is performing INT wipes,
then the rear wiper automatically performs
INT wipes.
This feature can be turned on or off. Go to
Settings > Vehicle > Comfort and
Convenience > Auto Wipe in Reverse Gear >
Select ON or OFF.
The windshield washer reservoir is used for
the windshield, rear window, and Rear
Camera Mirror, if equipped. See

about the operation of the vehicle is
projected onto the windshield. The image is
projected through the HUD lens on top of
the instrument panel. The information
appears as an image focused out toward the
front of the vehicle.
Caution
If you try to use the HUD image as a
parking aid, you may misjudge the
distance and damage your vehicle. Do not
use the HUD image as a parking aid.
The HUD information can be displayed in
various languages. The speedometer reading
and other numerical values can be displayed
in either English or metric units.
The language selection is changed through
the radio, and the units of measurement are
changed through the instrument cluster. See

Maintenance When Trailer Towing
The vehicle needs service more often when
used to tow trailers. SeeMaintenance
Schedule 0330. 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 0271.
Trailer Towing
Caution
Towing a trailer improperly can damage
the vehicle and result in costly repairs
not covered by the vehicle warranty. To
tow a trailer correctly, follow the
directions in this section and see your
dealer for important information about
towing a trailer with the vehicle. Trailering is different than just driving the
vehicle by itself. Trailering means changes in
handling, acceleration, braking, durability,
and fuel economy. Successful, safe trailering
takes correct equipment, and it has to be
used properly.
The following information has many
time-tested, important trailering tips and
safety rules. Many of these are important
for your safety and that of your passengers.
Read this section carefully before pulling a
trailer.
Trailer Weight
{Warning
Never exceed the towing capacity 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.
Trailer Weight Ratings
When towing a trailer, the combined weight
of the vehicle, vehicle contents, trailer, and
trailer contents must be below all of the
maximum weight ratings for the vehicle
including:
.Gross Combined Weight Rating (GCWR)
.Gross Vehicle Weight Rating (GVWR)
.Maximum Trailer Weight Rating
.Gross Axle Weight Rating-Rear (GAWR-RR)
.Maximum Trailer Tongue Weight Rating
See “Weight-Distributing Hitch Adjustment”
under Towing Equipment 0256 to
determine if equalizer bars are required to
obtain the maximum trailer weight rating.
See “Trailer Brakes” underTowing
Equipment 0256 to determine if brakes are
required based on the trailer weight.
The only way to be sure the weight is not
exceeding any of these ratings is to weigh
the tow vehicle and trailer combination,
fully loaded for the trip, getting individual
weights for each of these items.

Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system that
indicates when to change the engine oil and
filter. This is based on a combination of
factors which 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 may
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 willperform 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. Using the DIC controls on the right side of the steering wheel, display
REMAINING OIL LIFE on the DIC. See
Driver Information Center (DIC) 0111.
When remaining oil life is low, the
CHANGE ENGINE OIL SOON message will
appear on the display.
2. Press
Von the DIC controls and hold
down for a few seconds to clear the
CHANGE ENGINE OIL SOON message and
reset the oil life at 100%. Be careful not to reset the oil life display
accidentally at any time other than after
the oil is changed. It cannot be reset
accurately until the next oil change.
The system is reset when the CHANGE
ENGINE OIL SOON message is off.
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.
Automatic Transmission Fluid
A transmission fluid leak is the only reason
for fluid loss. If a leak occurs, take the
vehicle to your dealer and have it repaired
as soon as possible.
Caution
Use of the incorrect automatic
transmission fluid may damage the
vehicle, and the damage may not be
covered by the vehicle warranty. Always
use the correct automatic transmission
fluid. See Recommended Fluids and
Lubricants 0334.
See your dealer to have the fluid and filter
changed at the intervals listed in the
Maintenance Schedule 0330.
