In c hoosing an oil, you want the p rop er q uality and visc osity, as well
as one that will ad d to fuel ec onomy. The following tab le lists the rec -
ommend ed visc osities and ap p lic ab le temp eratures.
When ad d ing oil, d ifferent b rand s may b e used tog et her as long as
they are the same API c lassific ation and SAE visc os ity as those rec -

Power steering fluid
The p ower steering fluid exp and s g reatly as its tem
p erature rises; the
fluid level d iffers ac c ord ing to fluid temp erature. Therefore, the d ip stic k
has two d ifferent c hec king rang es for hot and c old fluid s.
Checking the fluid level when the fluid is hot
WARNING
Be careful not to burn yourself because the fluid may be hot.
CAUTION
When power steering fluid is being added, use only clean fluid,
and be careful not to allow any dirt into the tank. And never use
different brands together. Avoid spilling fluid when adding it in the tank.
Chec k the p ower steering fluid level monthly.
1. Drive the vehic le several miles to raise the temp erature of the p ow-
er steering fluid up to normal op erating temp eratur e, ab out 140F
(60 C).
2. Park the vehic le on a level surfac e, and stop the eng ine.
3. Turn the reservoir c ap c ounterc loc kwise to remove the fluid level
d ip stic k, wip e the d ip stic k c lean, and reinsert it.
