Towing Requirements — Tires
 Do not attempt to tow a trailer while using a compact
spare tire.
 Do not drive more than 50 mph (80 km/h) when towing
while using a full size spare tire.
 Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle
 Check the trailer tires for proper tire inflation pressures
before trailer usage.
 Check for signs of tire wear or visible tire damage
before towing a trailer page 416.
Ú
 For the proper tire replacement procedures
page 416. Replacing tires with a higher load carrying
Ú
capacity will not increase the vehicle's GVWR and
GAWR limits.
Towing Requirements — Trailer Brakes
 Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
 An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu-
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic
brake controller is not required.
 Trailer brakes are recommended for trailers over
1,000 lb (453 kg) and required for trailers in excess
of 2,000 lb (907 kg).
 Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have an
accident.
Ú page 416.
 Towing any trailer will increase your stopping
distance. When towing, you should allow for addi-
tional space between your vehicle and the vehicle in
front of you. Failure to do so could result in an acci-
dent.
If the trailer weighs more than 1,000 lb (453 kg)
loaded, it should have its own brakes and they should
be of adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal
effort, and longer stopping distances.
Integrated Trailer Brake Module (ITBM) —
If Equipped
Your vehicle may have an ITBM for Electric and Electric
Over Hydraulic (EOH) trailer brakes.
NOTE:
This module has been designed and verified with electric
trailer brakes and new electric over hydraulic systems.
Some previous EOH systems may not be compatible
with ITBM.
WARNING!
CAUTION!
STARTING AND OPERATING
Integrated Trailer Brake Module (ITBM)
1 — GAIN Adjustment Button
2 — GAIN Adjustment Button
3 — Manual Brake Control Lever
The user interface consists of the following:
Manual Brake Control Lever
Slide the manual brake control lever to the left to activate
power to the trailer's electric brakes independent of the
tow vehicle's brakes. If the manual brake control lever is
activated while the brake is also applied, the greater of the
two inputs determines the power sent to the trailer brakes.
The trailer and the vehicle's stop lamps will come on when
braking normally with the vehicle brake pedal. Only the
trailer stop lamps will come on when the manual brake
control lever is applied.
