engine is first started. If the light stays on or comes on
while driving, stop the vehicle and shut off the engine.
DO NOT operate the vehicle until the cause is corrected.
NOTE:This light does not indicate how much oil is in
the engine. The engine oil level must be checked under
the hood.
Charge System Light
A red LED light on the Voltage gauge will illumi-
nate when there is a charging system malfunction
or a possible accessory drive belt failure.
CAUTION!
The accessory belt also drives the water pump.
Operating the vehicle with a failed belt can cause
engine overheating and possible severe engine dam-
age.

Gauges
Tachometer
This gauge shows engine speed in revolutions-
per-minute (RPM) times 1,000. Avoid excessive
engine speeds in any part of the red warning
zone, particularly when driving downhill or in
lower gears.
Coolant Temperature Gauge
This gauge shows the engine coolant tempera-
ture. The gauge pointer will likely show higher
temperatures when driving in hot weather, up
mountain grades, or in heavy stop and go
traffic. If the red LED light turns on, stop the vehicle and
turn off the engine until the cause is corrected.
Oil Temperature Gauge
This gauge shows the oil temperature. The
gauge pointer will likely show higher tempera-
tures when driving in hot weather, up moun-
tain grades, or in heavy stop and go traffic. If
the red LED light turns on, stop the vehicle and turn off
the engine until the cause is corrected.
Oil Pressure Gauge
This gauge shows engine oil pressure when the
engine is running. The pressure will vary with
engine speed, oil viscosity, and engine tem-
perature. Oil pressures will be higher as the
engine is warming up. The normal operating pressure is
between 20 and 80 psi (pounds per square inch). If the
pointer remains in the red range, turn off the engine until
the cause is corrected.

Recommended Shift Speeds
To use your manual transmission for fuel economy it
should be upshifted as listed below. Shift at the vehicle
speeds listed for acceleration. Earlier upshifts during
cruise conditions (relatively steady speeds) will result in
increased fuel economy, and may be used as indicated.
MANUAL TRANSMISSION
RECOMMENDED SHIFT SPEEDS
1-2 2-3 3-4 4-5 5-6
MPH 15 25 40 45 50
(km/h) (24) (40) (64) (72) (80)
Higher upshift speeds may be used to obtain a desired
acceleration rate.
Skip Shift Light
There are times when you must shift directly from First to
Fourth gear instead of from First to Second. An amber
(LED) arrow on the instrument cluster will light up
during these times. This is to help you get the best
possible fuel economy.
The shift arrow will light up when engine coolant is
higher than 106ÉF (41ÉC), vehicle speed is greater than 12
MPH and less than 20 MPH, engine speed is less than
1322 RPM, you are in 1st gear and you are at 1/4 throttle
or less.
When the arrow is lit, the shift mechanism will only
allow shifts from First to Fourth gears. After you shift to
Fourth gear, you can press the clutch in and shift to
another forward gear.
Downshifting - Proper downshifting will improve fuel
economy and prolong engine life.

²In city trafficÐWhile moving, shift into the highest
gear possible to reduce engine RPM.
NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the cooling system and turning off the A/C removes this
heat. You can also turn the Temperature control to
maximum heat, the Mode control to floor, and the fan
control to High. This allows the heater core to act as a
supplement to the radiator and aids in removing heat
from the cooling system.WARNING!
A hot cooling system is dangerous. You or others
could be badly burned by steam or boiling coolant.
If your temperature gauge pointer is in the red area,
turn off the engine immediately. You may want to
call a service center for service. If you decide to look
under the hood yourself, see Section 7 of this
manual. Follow the warnings under the Radiator
Cap paragraph.

Cooling System
WARNING!
You or others can be badly burned by hot coolant or
steam from your radiator. If you see or hear steam
coming from under the hood, don't open the hood
until the radiator has had time to cool. Never try to
open a cooling system pressure cap when the radia-
tor is hot.
Inspection
Coolant protection checks should be made every 12
months (before the onset of freezing weather, where
applicable). If coolant is dirty or rusty in appearance, the
system should be drained, flushed and refilled with fresh
coolant. Check the front of the radiator for any accumu-
lation of bugs, leaves, etc.Check the coolant bottle tubing for condition and tight-
ness of connection at reserve tank and radiator. Inspect
the entire system for leaks.
NOTE:Check the front of the radiator for debris (leaves,
paper, etc.) regularly. A build up of such material could
lead to engine overheating.
Do not remove the cooling system pressure cap when the
cooling system is hot.
Cooling System Ð Drain, Flush and Refill
The cooling system should be drained, flushed and
refilled at the intervals shown on the Maintenance Sched-
ules.
If the solution is dirty and contains a considerable
amount of sediment, clean and flush with a reliable
cooling system cleaner. Follow with a thorough rinsing to
remove all deposits and chemicals. Discard old antifreeze
solution according to recommended procedure.

Engine Coolant Disposal
Used ethylene glycol based engine coolant is a regulated
substance requiring proper disposal. Check with your
local authorities to determine the disposal rules for your
community. Do not store ethylene glycol based engine
coolant in open containers or allow it to remain in
puddles on the ground. Prevent ingestion by animals or
children. If ingested by a child, contact a physician
immediately.
Selection Of Coolant
Use only the manufacturer's recommended coolant. Re-
fer to the Recommended Fluids, Lubricants and Genuine
Parts section for the correct coolant type.
CAUTION!
Mixing of coolants other than specific (non-HOAT),
may result in engine damage that may not be cov-
ered under the new vehicle warranty, and decreased
corrosion protection. If a non-HOAT coolant is intro-
duced into the cooling system in an emergency, it
should be replaced with the specified coolant as
soon as possible.
Do not use plain water alone or alcohol base anti-
freeze products. Do not use additional rust inhibi-
tors or antirust products, as they may not be compat-
ible with the radiator coolant and may plug the
radiator.
This vehicle has not been designed for use with
Propylene Glycol based coolants. Use of Propylene
Glycol based coolants is not recommended.

Adding Coolant
DO NOT remove the pressure cap when checking cool-
ant. When adding coolant or refilling system, a 50%
solution of ethylene glycol antifreeze coolant in water
should be used. Higher concentrations (not to exceed
65%) are required if temperatures below ±37ÉF are antici-
pated.
Use only high purity water such as distilled or deionized
water when mixing the water / antifreeze solution. The
use of lower quality water will reduce the amount of
corrosion protection in the engine cooling system.
NOTE:It is the owner's responsibility to maintain the
proper level of protection against freezing according to
the temperatures occurring in the area where the vehicle
is operated.WARNING!
Never add coolant to the radiator when the engine is
overheated. Do not loosen or remove pressure cap to
cool overheated engine. The coolant is under pres-
sure and severe scalding could result.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
coolant, and to insure that coolant will return to the
radiator from the coolant reserve tank.
The pressure cap should be inspected and cleaned if there
is any accumulation of foreign material on the sealing
surfaces.

WARNING!
The warning words ªDO NOT OPEN HOTº on the
pressure cap are a safety precaution. Never add
coolant to the radiator when the engine is over-
heated. Do not loosen or remove the pressure cap to
cool overheated engine. Heat causes pressure to
build up in the cooling system. To prevent scalding
or injury, do not remove the pressure cap while the
system is hot or under pressure.
Coolant Level
The coolant recovery bottle provides a visual method for
checking the coolant level without removing the pressure
cap.
With the engine warmed up, the coolant level should be
between MIN and MAX on the coolant recovery bottle.

When additional coolant is needed to maintain the
proper level, it should be added to the coolant recovery
bottle.
Points to Remember
²
Do not overfill the bottle.
²Check coolant freeze point in the coolant bottle. If
antifreeze needs to be added, contents of the coolant
bottle also must be protected against freezing.
²If frequent coolant additions are required, or if the
level in the bottle does not drop when the engine cools,
the cooling system should be pressure tested for leaks.
²Maintain coolant concentration of 50% ethylene glycol
(minimum) with recommended antifreeze for proper
corrosion protection of your engine that contains alu-
minum components.
²Make sure that the radiator and bottle overflow hoses
are not kinked or obstructed.
²Keep the front of the radiator clean. If your vehicle has
air conditioning, keep the front of the condenser clean
also.
²Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory cooling performance.
Hoses and Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, checking, tears, cuts, abrasions,
and excessive swelling suggest deterioration of the rub-
ber. Pay particular attention to those hoses nearest to
high heat sources such as the exhaust manifold. Inspect
