OWNER’S WARRANTY RESPONSIBILITIES:
As the motor vehicle engine owner, you are responsible for the performance of the required maintenance listed in this manual. Mack Trucks, Inc. recommends that you retain all receipts covering maintenance of your vehicle, but Mack Trucks, Inc. cannot deny warranty solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance listed in other manuals which were supplied with your vehicle.

You are responsible for presenting your motor vehicle engine to a MACK dealer as soon as a problem exists. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days. As the motor vehicle engine owner, you should also be aware that Mack Trucks, Inc. may deny you warranty coverage if your vehicle or a part has failed due to abuse, neglect, improper maintenance, or unapproved modifications.

Repairs by MACK Dealers,
Sub-Dealers and Service Dealers Repairs covered by the California Emission Control Systems Warranty will be performed by any authorized MACK repair facility at his place of business with no charge for parts and labor (including diagnosis), using MACK parts for any part of the emission control systems covered by this warranty and found defective.

Repairs by Non-MACK Facilities
Owners may elect to have maintenance, replacement, or repair of emission control systems performed by any repair facility, and may elect to use parts other than MACK parts without invalidating the warranty on other components, but the cost of such service or parts will not be covered by MACK under its warranty.

Use of Non-MACK Parts
Use of replacement parts which are not the equivalent of MACK parts may impair the effectiveness of emission control systems. If other than MACK parts are used, the owner should obtain assurances that such parts are warranted by their manufacturer to be the equivalent of MACK parts in performance and durability. MACK assumes no liability under this warranty with respect to parts other than MACK parts however, the use of non-MACK parts does not invalidate the warranty on other components unless non-MACK parts cause damage to warranted parts.

Maintenance and Maintenance Records
The vehicle owner is responsible for the performance of all required maintenance specified in this manual. MACK will not deny a warranty claim solely because there is no record of maintenance however, MACK may deny a warranty claim if failure to perform required maintenance results in the failure of a warranted part. Receipts or other records covering the performance of scheduled maintenance should be retained to answer questions that may arise concerning maintenance. Maintenance records should be transferred to subsequent owners if the vehicle is sold.

TRUCK-TRACTOR CONSPICUITY
To make the vehicle more conspicuous when approached from the rear (in times when visibility is reduced), all truck/tractors built on or after July 1, 1997 have reflective devices applied on the rear of the cab and on the mudflaps or mudflap hanger brackets if mudflaps or mudflap hanger brackets are supplied from the factory. If mudflaps or mudflap hanger brackets are not supplied from the factory, reflective devices will be applied on the rear, lower portion of the cab. Refer to the illustration. Locations of these reflective devices may vary from this illustration, depending on the cab model and/or equipment added to the rear of the cab.

  1. White Reflective Devices Back of Cab
  2. Red and White Reflective Devices (when not equipped with mudflaps and brackets)
  3. Red and White Reflective Devices on Mudflaps or Hanger Brackets

Note: The truck-tractor conspicuity standard is intended to make the tractor as visible as the trailer when the truck tractor is being operated in a bobtail condition.

Deck Plate Access
There may be a time when you will need to climb up behind the cab. If your vehicle is equipped with a deck access package, steps and a handhold are provided so you can get to this area safely. Review the rules in the Three-Limb Contact section before climbing behind the cab.

Climbing Up
These procedures are illustrated on the following page:

  1. Grab the handhold with both hands. Then move one foot to the bottom step. (See figure 1.)
  2. While still gripping the handhold, and with one foot planted firmly on the bottom step, move your other foot to the middle step. (See figure 2.)
  3. Then with one foot planted firmly on the middle step, move the other foot to the top step. (See figure 3.)
  4. Finally, move your other foot from the middle step onto the deck plate. (See figure 4.)

Climbing Down
To climb down from behind the cab, follow the illustrations in reverse order:

  1. Grab the handhold with both hands and move one foot to the top step. (See figure 4.)
  2. While firmly gripping the handhold, and with one foot on the top step, move your other foot to the middle step. (See figure 4.)
  3. Then with one foot planted firmly on the middle step, place the other foot on the bottom step. (See figure 3.)
  4. With both hands still gripping the handhold, move your other foot from the middle step to the ground. (See figure 2.)
  5. Finally, move foot from bottom step to the ground. (See figure 1.)

Outside Mirror Heater
In areas of frequent snowfall and ice, it may be beneficial to install heated mirrors which will defrost and de-ice cab mirrors. Heated mirrors eliminate the need to pull off the highway and stand on the roadside to scrape ice and snow from the mirrors during winter driving conditions. Heated mirrors are available either cab mounted or fender mounted.
