down condition; check for improper
tongue load, overload, worn suspension
or other possible causes of either condi-
tion.
. Always secure items in the trailer to
prevent load shift while driving.
. Keep the cargo load as low as possible in
the trailer to keep the trailer center of
gravity low.
. Load the trailer so approximately 60% of
the trailer load is in the front half and
40% is in the back half. Also make sure
the load is balanced side to side.
. Check your hitch, trailer tire pressure,
vehicle tire pressure, trailer light opera-
tion, and trailer wheel lug nuts every time
you attach a trailer to the vehicle.
. Be certain your rearview mirrors conform
to all federal, state or local regulations. If
not, install any mirrors required for
towing before driving the vehicle.
. Determine the overall height of the
vehicle and trailer so the required clear-
ance is known.
Trailer towing tips
In order to gain skill and an understanding of
the vehicle’s behavior, you should practice
turning, stopping and backing up in an area
which is free from traffic. Steering stability,
and braking performance will be somewhat different than under normal driving condi-
tions.
.
Always secure items in the trailer to
prevent load shift while driving.
. Lock the trailer hitch coupler with a pin or
lock to prevent the coupler from inad-
vertently becoming unlatched.
. Avoid abrupt starts, acceleration or
stops.
. Avoid sharp turns or lane changes.
. Always drive your vehicle at a moderate
speed. Some states or provinces have
specific speed limits for vehicles that are
towing trailers. Obey the local speed
limits.
. When backing up, hold the bottom of the
steering wheel with one hand. Move
your hand in the direction in which you
want the trailer to go. Make small
corrections and back up slowly. If possi-
ble, have someone guide you when you
are backing up.
Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is
not recommended; however, if you must do
so:
CAUTION
If you move the shift lever to the P
(Park) position before blocking the
wheels and applying the parking brake,
transmission damage could occur.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the downhill side of the vehicle and trailer
wheels.
3. After the wheel blocks are in place, slowly release the brake pedal until the
blocks absorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park).
6. Four-Wheel Drive (4WD) models:
Make sure that the 4WD shift switch is
engaged in the AUTO, 4HI or 4LO
position and the Automatic Transmission
(AT) park warning light is turned off.
7. Turn off the engine.
To drive away:
1. Apply and hold the brake pedal.
2. Start the engine.
3. Shift the transmission into gear.
Technical and consumer information10-27

— the Forward Emergency Braking(FEB) with pedestrian detection sys-
tem
— the Predictive Forward Collision Warning (PFCW) system
. Some states or provinces have specific
regulations and speed limits for vehicles
that are towing trailers. Obey the local
speed limits.
. Check your hitch, trailer wiring harness
connections, and trailer wheel lug nuts
after 50 miles (80 km) of travel and at
every break.
. When launching a boat, do not allow the
water level to go over the exhaust tail
pipe or rear bumper.
. Make sure you disconnect the trailer
lights before backing the trailer into the
water or the trailer lights may burn out.
When towing a trailer, the transmission
fluid should be changed more frequently.
For additional information, see “9. Main-
tenance and schedules” section.
TOW mode
Using TOW mode is recommended when
pulling a heavy trailer or hauling a heavy
load. Push the TOW mode switch to activate
TOW mode. The TOW mode indicator light
in the meter illuminates when TOW mode is
selected. Push the TOW mode switch again to turn TOW mode off. TOW mode is
automatically cancelled when the ignition
switch is placed in the OFF position.
TOW mode includes the following features:
.
Grade logic — Adjusts transmission shifts
when pulling a trailer or hauling a load up
a grade.
. Downhill Speed Control (DSC) — auto-
matically downshifts when driving down
a grade with a trailer or heavy load to
help control vehicle speed.
Driving the vehicle in the TOW mode with no
trailer/load or light trailer/light load will not
cause any damage. However, fuel economy
may be reduced and the transmission/
engine driving characteristics may feel unu-
sual.
When towing a trailer, the transmission
fluid should be changed more frequently.
For additional information, see “9. Main-
tenance and schedules” section.
Trailer Sway Control
To minimize trailer sway, your vehicle may
apply braking to individual wheels based on
input from your vehicle sensors and vehicle
speed. Trailer Sway Control is a function of
the Vehicle Dynamic Control (VDC) system
and is active when the VDC function is
enabled.
CAUTION
If the VDC OFF switch is on (meaning
VDC system OFF), the Trailer Sway
Control is also disabled.
When Trailer Sway Control is in operation,
the VDC warning light blinks. When vehicle
control is regained, VDC warning light will
turn OFF.
For additional information about the VDC
system, see “Vehicle Dynamic Control (VDC)
system” (P.5-133).
If Trailer Sway Control activates:
1. Take your foot off the accelerator pedal to allow the vehicle to coast and steer as
straight ahead as the road conditions
allow. This combination will help stabilize
the vehicle.
CAUTION
Do not try to correct trailer sway by
steering or applying the brakes.
2. When the trailer sway stops, gently apply the brakes and pull to the side of
the road in a safe area.
