background image

When stopped in congested or

heavy traffic during hot

weather, place the gearshift in

position P to aid engine and

transmission cooling and to
help A/C performance.

Turn off the speed control with
heavy loads or in hilly terrain.
The speed control may turn off
automatically when you are
towing on long, steep grades.

Shift to a lower gear when
driving down a long or steep
hill. Do not apply the brakes
continuously, as they may

overheat and become less

effective.

If your transmission is equipped
with a Grade Assist or

Tow/Haul feature, use this

feature when towing. This

provides engine braking and

helps eliminate excessive

transmission shifting for
optimum fuel economy and

transmission cooling.

If your vehicle is equipped with

AdvanceTrac with RSC, this

system may turn on during
typical cornering maneuvers

with a heavily loaded trailer.
This is normal. Turning the

corner at a slower speed while

towing may reduce this

tendency.

If you are towing a trailer

frequently in hot weather, hilly

conditions, at the gross

combined weight rating (or any

combination of these factors),
consider refilling your rear axle
with synthetic gear lubricant (if
the axle is not already filled
with it). See Capacities and
Specifications (page 301).

Allow more distance for
stopping with a trailer
attached. Anticipate stops and
brake gradually.

Avoid parking on a grade.

However, if you must park on a

grade:

1. Turn the steering wheel to

point your vehicle tires away

from traffic flow.

2. Set your vehicle parking brake.
3. Place the automatic

transmission in position P.

4. Place wheel chocks in front

and back of the trailer wheels.
(Chocks not included with

vehicle.)

Your vehicle may be equipped
with a temporary or conventional

spare tire. A "temporary" spare tire
is different in size (diameter or

width), tread-type (All-Season or

All Terrain) or is from a different

manufacturer than the road tires
on your vehicle. Consult
information on the tire label or
Safety Compliance label for
limitations when using.
