2008 Nissan Sentra Owner’s Manual — Questions and Answers

What is the maximum recommended antifreeze mixture ratio for coolant?

Only Genuine NISSAN Long Life Antifreeze/Coolant or an equivalent should be used, mixed at a 50% antifreeze to 50% demineralized or distilled water ratio. Using other coolant types or colors, such as orange, can damage the cooling system. Owner’s Manual, p. 250

How do I install a front-facing child seat using the LATCH anchors?

Position the child restraint on the seat following the maker’s instructions, then clip the restraint’s anchor attachments onto the vehicle’s LATCH lower anchors and confirm they’re locked in. Press down and back on the restraint with your knee to remove slack while pulling the webbing tight, then attach any top tether strap to its anchor point.

1. Position the child restraint on the seat per its manufacturer’s instructions.
2. Secure the anchor attachments to the LATCH lower anchors and verify proper attachment.
3. Make sure the restraint’s back sits firmly against the vehicle seatback.
4. For webbing-mounted restraints, press down and rearward with your knee while tightening the anchor webbing to remove slack.
5. If equipped, route and secure the top tether strap to the tether anchor point.
6. Push and tug the restraint near the LATCH attachment to confirm it moves less than 1 in (25 mm), retightening or repositioning if needed.

What should I check before adding coolant to a 2008 Nissan Sentra?

Make sure the engine is cold before checking, since the reservoir and radiator must not be opened hot. Check the reservoir level against the MIN and MAX marks, and if it’s empty, also check coolant level directly in the radiator before topping off.

1. Let the engine cool completely before opening any cap
2. Check the coolant level in the reservoir against MIN and MAX marks
3. If the reservoir is empty, check the radiator level too
4. Fill the radiator to the filler opening and the reservoir to MAX if needed

What does the front passenger air bag status light mean on a 2008 Nissan Sentra?

It shows whether the front passenger air bag is on or off. When installing a forward-facing child restraint up front, the seat must be moved to the rearmost position and this light must be illuminated to confirm the air bag is OFF. Owner’s Manual, p. 48

How often does a 2008 Nissan Sentra need an oil change under tough driving conditions?

A 2008 Nissan Sentra may need oil and filter changes more often than the standard schedule if driven mostly short cold-weather trips, in dusty areas, with extensive idling, while towing, or during stop-and-go commuting. Owner’s Manual, p. 290

How can you tell the 2008 Nissan Sentra keyless entry locked the doors?

When all doors are closed, pressing the keyfob button locks them while the horn beeps and hazard lights flash; if a door was open, doors still lock but the horn stays silent and lights don’t flash. Owner’s Manual, p. 121

Can I ride in a 2008 Nissan Sentra with the seatback reclined?

No. The 2008 Nissan Sentra manual warns against riding with the seatback reclined because the shoulder belt won’t rest against your body. In a crash you could be thrown into the belt or slide under the lap belt, causing serious neck or internal injuries. Owner’s Manual, p. 18
