Instrument  CIuster 
Your instrument  cluster is designed  to  let  you  know  at  a  glance  how  your 
vehicle  is  running.  You’ll  know  how  fast  you’re  going,  ab\
out  how  much  fuel 
you  have  and  many  other  things  you’ll  need  to  know  to  driv\
e  safely  and economically. 
Tachometer  Cluster 
If you  have  the  tachometer  cluster,  it  looks  different  but  will  t\
ell  you 
everything  the  standard  cluster  does,  with  the  addition 
of displaying  your 
engines  revolutions  per  minute  (rpm). 
Speedometer  and  Odometer 
K2322 
Your  speedometer  lets  you  see  your  speed  in  both  miles  per  hour  (\
mph)  and 
kilometers  per  hour  (kmlh).  Your  odometer  shows  how  far  your  vehicle  has 
been  driven,  in  either  miles  (used  in the  U.S.)  or  kilometers  (used  in 
Canada). 
If you  have  the  Sport  Performance  Model  (RPO  B4U),  your  speedome\
ter 
reading  will 
go to 110 mph (1 80 km/h). 
Tamper-Resistant  Odometer 
Your  odometer  is  tamper-resistant.  The  odometer  will  show  silver  line\
s 
between  the  numbers 
if someone  tries  to  turn it back. 
You  may  wonder  what  happens 
if your  vehicle  needs  a  new  odometer 
installed. 
If the  new  one  can  be  set  to the  mileage  total  of the  old  odometer, 
then  it must  be.  But 
if it  can’t,  then  it’s  set  at  zero,  and  a  label  must  be  p\

Heater  Output 
Optional Engine Block Heater 
If  your  engine  is equipped  with  an  optional  engine  block  heater,  you  can  use 
it  during  initial start-up  in  cold  weather  (20”F, 
-8”C, or  lower) to help  heat  the 
passenger  compartment  faster.  Because  an  engine  block  heater  war\
ms  the 
engine  coolant,  your  vehicle’s  heating  system  can  provide  som\
e  heat  as  soon 
as  you  start  the  engine. 
The  use 
of an  engine  block  heater  also  reduces  the  time  it takes  for  the 
engine  to reach  normal  operating  temperature,  and  shortens  the  time  it takes 
the  heater  to reach  full output.  For  more  information,  See  “Engine  Block 
Heater”  in  the  Index. 
Diesel Engine 
If you  idle  your  diesel  engine  for  a  long  time  when  it’s  cold\
  outside,  your 
heater  may  blow  out  cool  air.  This  is  normal.  When  you  increase  the \
 engine 
speed,  your  heater  should  blow  out  warmer  air. 
If it  doesn’t,  your  coolant 
level  may  be 
low. See  “Engine  Coolant’’  in the  Index  to find  out  how to 
check  your  coolant  level.
