Engine oil viscosity grades
SAE 5W-30 is the best viscosity
grade for your vehicle.
Do not use other viscosity grade oils
such as SAE 10W-30, 10W-40 or
20W-50.
Cold temperature operation:
If in an area of extreme cold, where
the temperature falls below -25°C, an
SAE 0W-30 oil should be used. An oil
of this viscosity grade will provide
easier cold starting for the engine at
extremely low temperatures. When
selecting an oil of the appropriate
Service and maintenance
viscosity grade be sure to always
select an oil that meets the dexos
specification.
■ Down to -25°C and below: 0W-30,
0W-40.
■ Down to -25°C: 5W-30, 5W-40.
■ Down to -20°C: 10W-30, 10W-40
(only for LXT).
■ Down to -15°C: 15W-30, 15W-40
(only for LXT).
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures.
The first figure, followed by a W,
indicates the low temperature
viscosity and the second figure the
high temperature viscosity.
Coolant and antifreeze
Use only silicate-free long life coolant
(LLC) antifreeze. approved for the
vehicle. Consult a workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C.

This concentration should be
maintained all year round. The use of
additional coolant additives that
intend to give additional corrosion
protection or seal against minor leaks
can cause function problems. Liability
for consequences resulting from the
use of additional coolant additives will
be rejected.
Brake and clutch fluid
Only use DOT4 brake fluid.
Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified
interval.
Brake fluid should be stored in a
sealed container to avoid water
absorption.
Ensure brake fluid does not become
contaminated.
Caution
Using brake fluid other than GM
recommended brake fluid may
cause corrosion to components of
