GAUGES
Speedometer: Indicates the
current vehicle speed.
Engine coolant temperature
gauge: Indicates engine coolant
temperature. At normal operating
temperature, the needle will be in
the normal range (between “H” and
“C”). If it enters the red section,
the engine is overheating. Stop
the vehicle as soon as safely
possible, switch off the engine
and let the engine cool.

OVERHEATING
If the temperature gauge indicates overheating and you experience
power loss, you hear a loud knocking or pinging noise, the engine is
probably too hot.
If this happens: 1. Drive safely to the side of the road and park off the right-of-way.
2. Shift the automatic transmission into P (Park) or the manual transmission into the neutral position, and apply the parking brake.
3. Turn off the air conditioner.
WARNING: Steam from an overheated engine is dangerous. The
escaping steam could seriously burn you. Open the hood ONLY
after steam is no longer escaping from the engine.

6. Install the dipstick making sure it is fully seated in the filler tube.
7. Remove the dipstick and inspect the fluid level. The fluid should bein the designated area for normal operating temperature or ambient
temperature.
Low fluid level
Do not drive the vehicle if the fluid
level is at the bottom of the dipstick
and the ambient temperature is
above 10°C (50°F).
Correct fluid level
The transmission fluid should be checked at normal operating
temperature 66°C-77°C (150°F-170°F) on a level surface. The normal
operating temperature can be reached after approximately 30 km (20
miles) of driving.
You can check the fluid without driving if the ambient temperature is
above 10°C (50°F). However, if fluid is added at this time, an overfill
condition could result when the vehicle reaches normal operating
temperature.
The transmission fluid should be in
this range if at normal operating
temperature (66°C-77°C
[150°F-170°F]).
The transmission fluid should be in
this range if at ambient temperature
(10°C-35°C [50°F-95°F]).
High fluid level
Fluid levels above the safe range
may result in transmission failure.
An overfill condition of transmission
fluid may cause shift and/or
engagement concerns and/or
possible damage.
High fluid levels can be caused by an overheating condition.
Adjusting automatic transmission fluid levels
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick and also in the
Lubricant specifications section in this chapter.
